Smart locks are different from traditional mechanical locks, but they are also based on the structure of traditional locks, combined with the application of biometric technology, and now there are locks with a higher level of technology and intelligence. A more intelligent lock in terms of user identification, safety and management, and the execution component of the door lock in the access control system. Different from traditional mechanical locks, smart locks are composite locks with safety, convenience and advanced technology. Mature technologies that use non-mechanical keys as user identification IDs, such as fingerprint locks, iris recognition access control (biometric identification, high security, no loss or damage; but inconvenient configuration, high cost), magnetic cards, radio frequency cards (non-contact Type, high safety, plastic material, easy to configure and carry, low price), TM card (contact type, high safety, stainless steel material, very convenient to configure and carry, low price). The structure of the smart lock is composed of mechanical inserts, electronic motherboards, fingerprint collectors and other components. The cooperation of these components gives the smart door locks more intelligence. 1. Panel The materials used in smart lock panels on the market are: zinc alloy, stainless steel, aluminum alloy, plastic and so on. 2. Lock body The material of the lock body is mainly stainless steel, but iron is also available. The lock body is mainly divided into two types: standard conventional lock body and non-standard lock body. 3. Circuit board The circuit board is the core of the smart lock, and the quality of the circuit board will affect the performance of the smart lock. 4. Motor The motor is the motor powered by the smart lock, and the power consumption is very small. When using a password or swiping a card or fingerprint to unlock, you will hear the sound of the motor turning. 5. Handle There are two types of handles: long handles and round handles. Different smart lock handles can be purchased according to different needs. 6. Decorative circle Not all smart locks are equipped with a decorative ring. Smart locks equipped with a decorative ring look more atmospheric, but the cost will be slightly higher. 7. Display The display screen has a blue light display and a white light display. Smart locks equipped with a display screen are more intuitive and easier to operate, but not all smart locks are equipped with a display screen. 8. Keyboard The keyboard of the smart lock usually uses the reflection of light to judge the input, and the keyboard light is mainly divided into two types: blue light and white light. Generally, the reflection of white light will be better than blue light, and the input will be more sensitive. 9. Fingerprint head There are two main types of fingerprint heads for smart locks, optical fingerprint heads and semiconductor fingerprint heads. Generally speaking, the price of semiconductor fingerprint heads is higher than that of optical fingerprint heads, but some optical fingerprint heads with more recognition points are more expensive than low-end semiconductor fingerprint heads. 10. Lock core The lock cylinder is an important factor in judging the price of a smart lock, because different levels of lock cylinder security levels are not the same, the use of ultra-C lock cylinder smart locks will be more secure in preventing technical mechanical unlocking. 11. Battery slot The current mainstream smart lock battery slots are 4 batteries and 8 batteries. 12. Anti-lock knob Basically all household smart locks are equipped with anti-lock knobs. 13. Slide cover There are two types of smart locks with sliding cover and without sliding cover (straight plate). The smart lock with sliding cover can effectively protect the smart operation unlocking part of the smart lock, such as the keyboard, fingerprint head, and display screen. This depends on the difference. Choose according to the occasion. 14. Bluetooth module This is the IoT part of the smart lock. The smart locks of some modules, coupled with the wifi magic box, can realize the IoT of the smart lock (it is also the most popular remote unlocking in recent years, online information push, online viewing of unlocking records). The communication protocol used by the smart lock is different, and the IoT part used inside the smart lock will also be different. 1. Pure mechanical lock body. As the name implies, the lock body has no electronic part, it is a simple mechanical structure, and it is no different from an ordinary mechanical lock body. For such lock bodies, manufacturers often adopt a through-hole design for the convenience of production and installation. What is through-hole design? A complete set of locks is divided into 3 parts, the front panel, the lock body and the rear panel. The transmission between the front and rear panels and the lock body (the lock tongue on the lock body will shrink when the handle on the panel is pressed as follows) is connected The square shaft between them (a long steel bar of 4 squares) is realized. The through-hole design means that a square shaft penetrates the entire lock body to connect the front and rear panels. Where is the smart lock? The smart part of the lock with this structure focuses on the outer panel, yes, you read that right, it is on the outer panel exposed to the outside. 2. Mechanical intelligent integrated lock body. As the name suggests, it is a lock body that combines intelligence and machinery. The most notable feature is that it drags a small tail (data cable), which needs to be connected to the inner panel. The working principle of this lock body is to use an intelligent system to control whether the internal mechanism of the lock body is combined with the square shaft to achieve the purpose of opening the door. In other words, the lock body is designed with two square shafts inside and outside, cutting the two square shafts inside and outside. Both are combined with the handle, the user needs to control the square shaft and the lock body to open the door, so no matter how you turn the square shaft outside the door without proper authorization, the door will not open. Understand the structure of smart door locks, and have a certain understanding of the internal lock body structure. Nowadays, there are many types of smart door locks, and the quality is mixed. How should we choose smart door locks to be more secure? The anti-theft structure of the smart lock is more secure, the anti-theft structure of the smart lock must meet the following conditions: Anti-drill, anti-pry panel, anti-small black box, anti-hacking. 1. The lock cylinder has an anti-drilling structure The lock cylinder is the heart of the smart lock, and the smart lock cylinder opens as soon as the lock is unlocked. The anti-theft lock cylinder must be an anti-drilling lock cylinder. The lock cylinder must be built-in anti-drilling beads, anti-drilling bolts, and anti-drilling pieces to protect the marbles and blades of the lock cylinder so that it will not be easily drilled when the electric drill is unlocked . This is the difference between anti-theft smart lock and non-theft smart lock. The anti-drilling lock core is not afraid of electric drills, and the non-drilling lock core can be opened as soon as it is drilled. 2. Smart lock with anti-theft structure The anti-theft structure of the smart lock must have: 1. The anti-drill lock cylinder has a protective cover, the protective cover must have an anti-drilling piece, and the lock cylinder needs a key to open the lock after the panel is pryed. 4. A two-stage unlocking method must be adopted. In this way: the lock core has two layers of anti-drilling protection, and the electric drill cannot be easily drilled. Even if the panel is picked, the lock cylinder is still fixed on the lock body and the lock cannot be opened. This is the basic condition for anti-drilling and anti-prying. Two-stage unlocking can increase the difficulty of unlocking the high-frequency device. 3. The main transmission structure is placed on the rear panel The motor, the mechanism linking the motor, the control switch, and the smart lock with the main circuit board on the back panel of the lock are safer. Under normal circumstances, it is safer to have the front panel to protect it. If the front panel is picked, it will not be opened. The shielding ability of the rear motor and the main transmission mechanism is also higher than that of the front smart door lock. 4. Data transmission is encrypted and protected A secure smart lock must be: an encryption chip, strict data encryption and decryption, and cloud server authentication. Unencrypted smart locks are very risky. 5. Anti-high frequency transmitter (small black box) to unlock The safe smart lock must add overload short circuit protection and voltage stabilization module to ensure that it will not restart when Tesla interferes, and the software design should add a restart and will not automatically unlock the protection program.
Antenk DIN41612 Connectors are a versatile two piece PCB connector set with feaures useful for many applications including connections for plug-in card and back-panel wiring, PCB to PCB attachment and peripheral connections for external interfaces. Features include a multitude of body sizes and styles with options that include selective contact loading, make and break contacts, contact lead length choices and contact plating variations each in .100" [2.54mm] or .200" [5.08mm] centerline spacing.
The DIN 41612 standard covers a series of two-piece backplane connectors widely used in rack-based telecommunication, computing, process control, medical, industrial automation, test and measurement and military/aerospace systems where long-term reliability is required. They consist of one to three rows of contacts in combinations of 16, 32, 48, 64, or 96 contacts on a 0.1-inch (2.54 mm) grid pitch. The 3 rows are labelled a, b and c and connectors up to 64 way if using a 96 way body can use either rows a+b or a+c. DIN 41612 Signal connectors can be rated to 1.5 amps per signal pin, at 500 volts, although these figures may be de-rated according to safety requirements or environmental conditions. Several hybrid power and coaxial configurations are available that can handle up to 5.6A or even 15A. This wealth of variations explains the very wide range of applications that they`re put to. For over 30 years these DIN 41612 `Euro Card` connectors to IEC 60603-2 have offered a highly reliable system for board interconnects. Precision contact density, low mating forces, a two piece protective design and many contact termination styles offer unlimited design opportunities. Termination methods include – straight PC, solder eyelet, wire wrap, crimp and [press fit" terminals. Insertion and removal force are controlled, and three durability grades are available. Standardisation of the connectors is a prerequisite for open systems, where users expect components from different suppliers to operate together; ept and Conec DIN 41612 are therefore fully intermateable with all other similarly compliant products from other manufacturers like Harting, Erni, Hirose and TE Connectivity, etc.
DIN 41612 Connectors are widely used in rack-based electrical systems. The standard performance of these connectors is a 2 A per pin current carrying capacity and 500 V working voltage. Both figures may be variable due to safety and environmental conditions.

The most common connector in the DIN product line is type C, which is widely used in VMEbus systems, the DIN 41612 standard has been upgraded to meet international standards IEC 60603-2 and EN 60603-2. In the past, ept used a comb supported press-fit tool for their type C and B press-fit female connectors. To be more competitive, ept has changed to flat-rock technology (just a flat piece of steel pushed on the top of the connector) as used by many other manufacturers.
