Description

Technical Field

[0001] This utility model relates to the field of connector terminal assemblies, specifically a drawer-type quick-release connector terminal assembly. Background Technology

[0002] In the field of electronic equipment and electrical connections, connector terminal assemblies are key components for realizing electrical connections. The stability and reliability of their performance directly affect the normal operation of the entire system. Among them, drawer-type quick-release connector terminal assemblies are widely used in various scenarios that require frequent plugging and unplugging due to their convenient installation and disassembly characteristics, such as module connections inside electronic equipment and rapid inspection and replacement of electrical equipment.

[0003] Traditional drawer-type quick-release connector terminal assemblies typically achieve electrical connection through the mutual insertion of male and female connectors. The fixing method relies primarily on the angled latch on the male connector and the corresponding side groove on the female connector for locking. When the male connector plug is inserted into the drawer-type slot of the female connector, the angled latch is compressed and elastically deformed during insertion. Once fully inserted, the latch retracts into the side groove due to its elastic restoring force, thus achieving a secure connection between the male and female connectors. Disassembly is easy by simply pressing the angled latch to dislodge it from the side groove, allowing the male connector to be easily pulled out of the female connector. However, because the angled latch is exposed on the outside of the connector terminal assembly, workers may accidentally touch it during daily operation or equipment operation. If accidentally touched, the latch may partially or completely dislodge from the side groove, causing the connection between the male and female connectors to loosen. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a drawer-type quick-release connector terminal assembly to solve the technical problem that the traditional drawer-type quick-release connector terminal assembly is prone to loosening of the male and female connectors due to the exposed angled flip-out tabs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drawer-type quick-release connector terminal assembly, including a female terminal and a male terminal, wherein the top front end and bottom front end of the female terminal and the male terminal are provided with anti-accidental contact components for locking the female terminal and the male terminal, the anti-accidental contact components including a fixing mechanism and a socketing mechanism, the fixing mechanism being fixedly connected to the female terminal, and the socketing mechanism being fixedly connected to the male terminal.

[0006] By adopting the above technical solution, anti-accidental contact components are set at the top and bottom front of the female and male terminals, which can effectively prevent the connection from becoming loose or disconnected due to accidental contact during use, ensuring the stability of the connection and improving the reliability and safety of the connector terminal assembly.

[0007] Furthermore, the fixing mechanism includes a fixing seat, and the back of the fixing seat is provided with an annular fixing groove.

[0008] By adopting the above technical solution, an annular fixing groove is opened on the back of the fixing seat of the fixing mechanism, which can accurately match the corresponding parts of the socketing mechanism to achieve stable socketing, enhance the locking effect of the anti-accidental contact component, and prevent the female terminal and male terminal from being accidentally separated.

[0009] Furthermore, the sleeve mechanism includes two mounting ears, and the inner sides of the two mounting ears are rotatably connected to two spring sleeves via bearings, with a collar provided at the sliding rod end of the spring sleeve.

[0010] By adopting the above technical solution, the inner sides of the two mounting ears of the sleeve mechanism are rotatably connected to the spring sleeve through bearings, and a collar is set at the end of the slide rod, making the sleeve operation flexible and convenient, and easily cooperating with the fixing mechanism to realize the quick locking and unlocking of the anti-accidental contact component.

[0011] Furthermore, the collar is fitted into the fixing groove, and the anti-accidental touch component is made of engineering plastic.

[0012] By adopting the above technical solution, the collar and the fixing groove are fitted together, which can firmly connect the fixing mechanism and the fitting mechanism, effectively preventing the anti-accidental touch component from loosening. The use of engineering plastic material makes the anti-accidental touch component lightweight and durable, reducing costs while ensuring performance.

[0013] Furthermore, the female terminal includes a female body, and the top and bottom rear ends of the female body are provided with viewing ports, and the viewing ports are provided with transparent glass.

[0014] By adopting the above technical solution, the top and bottom rear ends of the female connector body are provided with viewing ports with transparent glass, which allows operators to directly observe the status of the pins in the drawer-type slot, promptly detect problems such as dust and damage, facilitate maintenance and repair, and ensure the normal operation of the connector.

[0015] Furthermore, one end of the female connector body is provided with a drawer-type slot, and the drawer-type slot is provided with multiple pins. The male connector terminal includes a male connector body, one end of which is provided with a plug, and the plug is provided with multiple sockets.

[0016] By adopting the above technical solution, the female connector body is equipped with a drawer-type slot and pins, and the male connector body is equipped with a plug and a socket. This structure makes the connection operation simple and intuitive, and the pins and sockets are precisely aligned to ensure stable signal transmission and improve the connection efficiency and reliability of the connector terminal assembly.

[0017] Furthermore, the female head body has side grooves on both sides, the male head body has back pressure grooves on both sides, and the inner wall of the back pressure groove has a spring groove at the rear end.

[0018] By adopting the above technical solution, the female connector body has side grooves on both sides, and the male connector body has back pressure grooves and spring grooves on both sides.

[0020] By adopting the above technical solution, the reset rod and spring in the spring groove cooperate, and the inclined pry bar in the back pressure groove engages with the side groove, making connection and disassembly smoother. The spring provides elasticity, allowing the inclined pry bar to accurately engage and disengage, ensuring connection stability and ease of operation.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. This utility model incorporates an anti-accidental contact component. When the male and female terminals are connected, the operating mechanism rotates the spring sleeve, causing the collar to engage with the fixing groove, thus locking the male and female terminals at the top and bottom front ends. This locking method conceals the critical fixing parts inside the component. Furthermore, the engineering plastic anti-accidental contact component possesses sufficient strength and stability, making it less susceptible to accidental contact that could alter its connection state.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] Example 1:

[0031] A drawer-type quick-release connector terminal assembly, such as Figure 1-4As shown, the connector includes a female terminal 1 and a male terminal 2. The top and bottom front ends of both terminals are equipped with anti-accidental contact components 3 for locking them in place. These components include a fixing mechanism 301 and a socketing mechanism 302. The fixing mechanism 301 is fixedly connected to the female terminal 1, and the socketing mechanism 302 is fixedly connected to the male terminal 2. This structure, with the anti-accidental contact components 3 at the top and bottom front ends of the female and male terminals, offers significant advantages. In daily use, connector terminal assemblies may be subjected to external forces such as impacts and pulling. Without the anti-accidental contact components 3, accidental contact could easily cause the female terminal 1 and male terminal 2 to separate, leading to circuit interruption. The anti-accidental contact components 3 provide a locking function, securing the two terminals from both the top and bottom, greatly enhancing connection stability, reducing malfunctions caused by misoperation, and improving the reliability and safety of the connector terminal assembly. This makes it suitable for various scenarios requiring stable connections.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The fixing mechanism 301 includes a fixing seat 3011, with an annular fixing groove 3012 on its back. This annular fixing groove 3012 on the back of the fixing seat 3011 plays a crucial role. When the anti-accidental contact component 3 is working, it needs to reliably connect with the socketing mechanism 302 to lock the female terminal 1 and male terminal 2. The annular fixing groove 3012 provides a precise socketing position for the corresponding components of the socketing mechanism 302, allowing them to fit tightly together and form a stable connection structure. This design enhances the locking effect of the anti-accidental contact component 3, effectively preventing the female terminal 1 and male terminal 2 from accidentally separating under external force, thus ensuring the connection stability and safety of the connector terminal assembly.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4The sleeve mechanism 302 includes two mounting ears 3021. Two spring sleeves 3022 are rotatably connected to the inner sides of the two mounting ears 3021 via bearings. A collar 3023 is provided at the sliding end of each spring sleeve 3022. This structure provides numerous conveniences. When it is necessary to lock the female terminal 1 and male terminal 2 of the anti-accidental contact component 3, the position of the collar 3023 can be flexibly adjusted by rotating the spring sleeve 3022, allowing it to accurately align with the corresponding part of the fixing mechanism 301 for sleeve engagement. The bearing rotation connection makes operation smoother, reduces friction, and lowers the difficulty of operation. Similarly, during unlocking, the spring sleeve 3022 can be easily rotated to disengage the collar 3023, achieving rapid locking and unlocking of the anti-accidental contact component 3 and improving efficiency.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The collar 3023 engages with the fixing groove 3012. The anti-accidental contact component 3 is made of engineering plastic, and this engagement plays a crucial role in its stability. During the use of the connector terminal assembly, it is essential to ensure a stable connection between the female terminal 1 and the male terminal 2 to prevent connection failure due to loosening of the anti-accidental contact component 3. The precise engagement of the collar 3023 with the fixing groove 3012 provides reliable connection force, ensuring a tight fit between the fixing mechanism 301 and the engagement mechanism 302, effectively resisting external vibrations and tension. Furthermore, the use of engineering plastic, a material known for its light weight, high strength, and corrosion resistance, reduces the overall weight of the component, facilitating installation and use, while ensuring long-term stable operation in various environments, thus extending the service life of the connector terminal assembly.

[0035] Example 2:

[0036] See Figure 1 , Figure 2 , Figure 3 , Figure 4The female connector 1 includes a female connector body 101. The top and bottom rear ends of the female connector body 101 are provided with viewing ports 104, and transparent glass is provided on the viewing ports 104. This structure, with its transparent glass viewing ports 104 on the top and bottom rear ends of the female connector body 101, offers significant convenience. During the use of the connector terminal assembly, the state of the pins 103 within the drawer-type slot 102 is crucial to the stability and reliability of the connection. However, because the pins 103 are located inside the slot, it is difficult to directly observe their condition with traditional connectors. The viewing ports 104 allow operators to visually inspect the pins 103 for dust accumulation, damage, or bending without disassembling the connector. Once a problem is detected, it can be cleaned or repaired promptly, preventing connection failures caused by pin 103 issues, ensuring the normal operation of the connector terminal assembly, and improving the efficiency and stability of the equipment.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The female connector body 101 has a drawer-type slot 102 at one end, and multiple pins 103 are arranged inside the drawer-type slot 102. The male connector terminal 2 includes a male connector body 201, and a plug 202 is provided at one end of the male connector body 201. The plug 202 has multiple sockets. The female connector body 101 has a drawer-type slot 102 and pins 103, while the male connector body 201 has a plug 202 and sockets. This structural design has significant advantages. During the connection operation, the operator only needs to insert the plug 202 of the male connector terminal 2 along the drawer-type slot 102 of the female connector body 101, and the pins 103 and sockets can achieve precise alignment. The drawer-type slot 102 provides a clear insertion direction and space for the plug 202, making the connection process simpler and more intuitive, greatly reducing the difficulty of operation and improving the connection efficiency. At the same time, precise alignment can ensure that the signal is not interfered with during transmission, reduce signal loss and errors, improve the stability and reliability of signal transmission, and thus improve the overall performance of the connector terminal assembly.

[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4The female connector body 101 has side grooves 105 on both sides, and the male connector body 201 has back pressure grooves 203 on both sides. A spring groove 204 is formed at the rear end of the inner wall of the back pressure groove 203. This structure provides crucial assurance for the stable connection of the connector terminal assembly. During connection, the inclined tabs 207 within the back pressure grooves 203 on both sides of the male connector body 201 need to engage with the side grooves 105 on both sides of the female connector body 101 to achieve a fixed connection between the female terminal 1 and the male terminal 2. The back pressure grooves 203 provide space for the inclined tabs 207 to be installed and moved, allowing them to rotate and elastically deform under external force. The spring groove 204 provides a placement position for the relevant elastic elements. Through the action of the elastic elements, the inclined rocker arm 207 can be accurately inserted into the side groove 105 after being inserted into place, which enhances the stability of the connection and effectively prevents the female terminal 1 and the male terminal 2 from accidentally separating during use.

[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A reset rod 206 is slidably connected within the spring groove 204, and a spring 205 is provided at the end of the reset rod 206. Two inclined pry bars 207 are rotatably connected to the front end of the inner wall of the back pressure groove 203. The two inclined pry bars 207 can engage with the side groove 105. The reset rod 206 slides within the spring groove 204, cooperating with the spring 205, the rotatable inclined pry bars 207 within the back pressure groove 203, and the side groove 105 to achieve stable connection and quick assembly / disassembly. The spring 205 assists in the movement of the inclined pry bars 207, improving the user experience.

[0040] The implementation principle of this embodiment is as follows: First, when connecting the female terminal 1 and the male terminal 2, the plug 202 of the male terminal 2 is aligned with the drawer-type slot 102 of the female terminal 1 and inserted. During the insertion process, the two inclined pry bars 207 rotatably connected to the front end of the inner wall of the back pressure groove 203 on both sides of the male body 201 will rotate and generate elastic deformation due to the pressure of the female body 101. At the same time, the reset rod 206 in the spring groove 204 at the rear end of the inner wall of the back pressure groove 203 provides a certain buffer and reset assistance for the inclined pry bars 207 under the action of the spring 205. When the plug 202 is fully inserted, the inclined pry bars 207 are stuck into the side grooves 105 opened on both sides of the female body 101 due to their own elastic restoring force, thus initially realizing the connection and fixation of the female terminal 1 and the male terminal 2.

[0041] Subsequently, the anti-accidental contact component 3 is operated to further lock the female terminal 1 and the male terminal 2. Since the socketing mechanism 302 is fixedly connected to the male terminal 2 and the fixing mechanism 301 is fixedly connected to the female terminal 1, by rotating the two spring sleeves 3022 connected to the inner side of the mounting ear 3021 in the socketing mechanism 302 through the bearing, the collar 3023 at the sliding end of the spring sleeve 3022 gradually approaches the annular fixing groove 3012 opened on the back of the fixing seat 3011 in the fixing mechanism 301, and the collar 3023 is put into the fixing groove 3012. At this time, the anti-accidental contact component 3 locks the female terminal 1 and the male terminal 2 from the top front end and the bottom front end. The anti-accidental contact component 3 is made of engineering plastic material, which has a certain strength and stability. It can effectively prevent the operator from accidentally touching the inclined pry bar 207 during daily operation or equipment operation, causing it to fall out of the side groove 105, thus avoiding the loosening of the connection between the female terminal 1 and the male terminal 2.

[0042] When it is necessary to disassemble the female terminal 1 and the male terminal 2, first unlock the anti-accidental contact component 3. By rotating the spring sleeve 3022 in the opposite direction, the collar 3023 is dislodged from the fixing groove 3012, releasing the lock of the anti-accidental contact component 3 on the female terminal 1 and the male terminal 2. Then, press the inclined pry bar 207 in the back pressure groove 203 on both sides of the male body 201 to dislodge the inclined pry bar 207 from the side groove 105. At this time, the male terminal 2 can be easily pulled out from the female terminal 1.

[0043] In addition, during the use of the connector terminal assembly, the viewing ports 104 provided at the top and bottom rear ends of the female head body 101 have transparent glass that allows staff to directly observe the connection status between the pins 103 in the drawer-type slot 102 and the sockets on the plug 202. For example, they can check whether there is dust or debris accumulation affecting the contact, or whether the pins are bent or misaligned, so as to clean or repair them in time and ensure the normal use of the connector terminal assembly.
