Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a vehicle connector device. Background Technology

[0002] Connectors are common components used for electrical connections in automotive control circuits. They are usually connected to microswitches, resistors, etc. When in contact, this structure can transmit information or current, and is also called a connector.

[0003] In existing technologies, contact devices employ over-constraint to fit the pins and sockets in a shaft-hole fit to ensure stability during use and prevent plug and socket detachment. This results in excessive insertion and extraction forces, excessive wear or even damage to the pin holes. Alternatively, while spring-loaded locking and unlocking devices can buffer the constraint force and reduce shaft hole damage caused by over-constraint, the small spring contact area is prone to misalignment under vibration, leading to locking failure or jamming, affecting subsequent insertion and removal. Furthermore, overly complex locking structures complicate contact device connections, occupy more space, and make assembly of the connector inconvenient and compromise waterproofing. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defects of the locking structure in the prior art, thereby providing a vehicle connector device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A vehicle connector includes a first connector and a second connector, which are interlocked. The first connector has multiple pins near the second connector, and the second connector has multiple holes corresponding to the pins. A locking member is also threaded onto the second connector and is also interlocked with the first connector. A locking groove is provided on the first connector corresponding to the locking member. The locking member includes a water-blocking member abutting against the surface of the first connector and a locking member inserted into the first connector. The locking member is located on opposite sides of the water-blocking member.

[0007] By adopting the above technical solution, a locking component is set to ensure a tight connection between the first connector and the second connector, effectively preventing the connection from shaking, loosening, or falling off during movement, thereby avoiding signal transmission interruption or power failure. Compared with the existing over-restraint locking structure, this locking component design is simpler. The use of a locking plate and an elastic pad can reduce the point contact of the spring, preventing the spring from easily misaligning under vibration, which could lead to locking failure or jamming. In addition, the elastic pad can facilitate the smooth sliding of the locking plate, reducing the friction surface during connection, thereby reducing lock insertion wear and extending the service life of the connecting components.

[0008] Furthermore, the first connector includes a pin socket and a cable tray arranged side by side. The pin socket is snapped into the cable tray. Multiple snap-fit ​​strips extend from the side of the pin socket near the cable tray. The cable tray has multiple snap-fit ​​slots corresponding to the pin socket. A positioning card extends from one end of each snap-fit ​​slot. The positioning card is arranged along the length of the snap-fit ​​slot. The snap-fit ​​strip has a positioning groove corresponding to the positioning card.

[0009] By adopting the above technical solution, the pin socket achieves plug-in mating, and the additional cable rack is detachable, which facilitates the pulling out of other cables from the connector for operation, thus improving the functional selectivity of the connector; the positioning groove and positioning card cooperate to ensure a firm and stable connection between the cable rack and the pin socket.

[0010] Furthermore, a wire harness tube with its axis arranged along the length of the cable frame is fixed on the cable frame. The wire harness tube is located on the side of the cable frame away from the pin socket. A tightening tube extends from the end of the wire harness tube away from the second connector. The diameter of the tightening tube is smaller than the diameter of the wire harness tube. An outlet is provided above the end of the wire harness tube away from the tightening tube. The connection between the outlet and the wire harness tube is a rounded transition.

[0011] By adopting the above technical solution, the cable is gathered together by the tightening cylinder and introduced into the cable harness cylinder, and then led out through the outlet, which protects the cable at the end and avoids the cable at the end from breaking due to excessive bending.

[0012] Furthermore, a rectangular pin seat groove is provided on the side of the pin seat near the second connector. The corners at both ends of one long side of the pin seat groove are rounded. Multiple pins are provided in the pin seat groove. The pins extend out of the pin seat. A protective shell extends from the side of the pin seat away from the second connector. The protective shell is provided around the pins.

[0013] By adopting the above technical solution, the pin seat groove enables the insertion and snapping of the second connector, which facilitates the normal use of the connector device. The rounded corner on the front side of the pin seat groove makes it easy to distinguish the front and back of the second connector, thus facilitating the alignment of the pin and the socket. The protective shell protects the extended pin.

[0014] Furthermore, the second connector includes a socket and a connecting wire. The connecting wire is cylindrical and is located on the side of the socket away from the pin socket. The socket is shaped to correspond to the pin socket groove. The socket is also provided with multiple insertion holes corresponding to the pins. A protective seat is provided at the connection between the connecting wire and the socket. The protective seat is integrally formed with the socket and surrounds the outside of the socket.

[0015] By adopting the above technical solution, the socket and connecting wire configuration realize the function of the second connector, and the protective socket protects the connection between the connecting wire and the socket, thus extending the service life of the second connector.

[0016] Furthermore, the water-blocking component includes a connecting sleeve that is threadedly connected to the protective seat and a waterproof sleeve integrally formed with the connecting sleeve. The waterproof sleeve covers the outside of the socket and has a protective groove in the middle to accommodate the socket. The shape of the waterproof sleeve is similar to that of the socket. The connecting sleeve and the waterproof sleeve are also provided with through openings.

[0017] By adopting the above technical solution, the water-blocking component and the connecting line can be disassembled as a whole, which can be set according to needs, and does not affect the internal structure of the second connector, making it easy to disassemble directly in the future; the waterproof sleeve abuts against the surface of the first connector to reduce water vapor infiltration and increase the external protection of the second connector.

[0018] Furthermore, locking components are hinged to opposite sides of the waterproof sleeve along its length. Each locking component includes a locking plate, a locking clip, an abutment post, and a control shaft. The locking clip is fixed to one end of the locking plate near the protective shell and is located on the side where the two locking plates are close to each other. The locking clip has an inclined surface on the side away from the locking plate. Two fixing clips extend from the side of the locking groove near the pin seat groove, corresponding to the locking clip. The fixing clips abut against both ends of the locking clip. The abutment post is cylindrical and its axis is set along the width direction of the locking plate. The abutment post is fixed to the locking plate near the waterproof sleeve. The control shaft is fixed to the side wall of the waterproof sleeve. The abutment post is sleeved on the control shaft and rotatably connected to the control shaft.

[0019] Furthermore, the locking plate is provided with a retaining pad connected to the waterproof sleeve at the end away from the locking card. Under normal conditions, the locking plate and the waterproof sleeve are set perpendicularly. An elastic pad is also fixed in the locking groove on the side away from the pin seat groove. The elastic pad is set along the depth direction of the locking groove. The side of the elastic pad near the locking plate is inclined. The side area of ​​the elastic pad near the second connector is smaller than the side area away from the second connector. The side of the locking plate near the elastic pad is also provided with an inclined surface corresponding to the elastic pad.

[0020] By adopting the above technical solution, the locking plate is inserted into the locking groove. Upon insertion, the locking plate squeezes the elastic pad, allowing the locking clip to smoothly engage between the two fixing clips. During unlocking and disassembly, one end of the locking plates on both sides is operated and pinched. Due to the presence of the control shaft and the abutment post, the locking plate tilts away from the pinched end, squeezing the elastic pad and causing the locking clip to disengage from the fixing clips. The locking plate can then be easily pulled out. The inclined surface of the elastic pad cooperates with the inclined surface of the locking plate, allowing the locking plate to be smoothly inserted and locked. The inclined surface reduces friction during insertion, facilitating the locking plate to slide smoothly into the bottom, thus engaging the locking clip with the fixing clips and preventing the first and second connectors from falling off.

[0021] In summary, the technical solution of this utility model has the following advantages:

[0022] 1. The vehicle connector device provided by this utility model is equipped with a locking component to ensure a tight connection between the first connector and the second connector, effectively preventing the connection from shaking, loosening or falling off during movement, thereby avoiding signal transmission interruption or power failure. Compared with the existing over-restraint locking structure, the design of this locking component is simpler.

[0023] 2. The vehicle connector device provided by this utility model uses a locking plate and an elastic pad to reduce the point contact of the spring, avoid the spring from being easily misaligned under vibration, which could lead to locking failure or locking jamming, and the elastic pad can facilitate the smooth sliding of the locking plate, reduce the friction surface during connection, thereby reducing the wear of the locking insertion and extending the service life of the connecting parts.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0032] A vehicle connector, such as Figure 1 and Figure 2 As shown, the connector includes a first connector 1 and a second connector 2, which are interlocked. The first connector 1 has multiple pins 3 extending through it, and the second connector 2 has multiple holes 21 corresponding to the pins 3. A locking element 4 is also threaded onto the second connector 2 and is interlocked with the first connector 1. A locking groove 11 is provided on the first connector 1 corresponding to the locking element 4. The locking element 4 includes a water-blocking element 5 abutting against the surface of the first connector 1 and a locking element 6 inserted into the first connector 1. The locking element 6 is located on the upper and lower sides opposite to the water-blocking element 5. The locking element 4 ensures a tight connection between the first connector 1 and the second connector 2, effectively preventing connection wobbling, loosening, or detachment during movement, thus avoiding signal transmission interruption or power failure. Compared to existing over-restraint locking structures, this locking element 6 design is simpler.

[0033] like Figure 1 , Figure 2 and Figure 3As shown, the first connector 1 includes a pin socket 12 and a cable tray 13 arranged vertically side by side. The cable tray 13 is positioned above the pin socket 12. The pin socket 12 and the cable tray 13 are snapped together. Two snap-fit ​​strips 121 extend from the side of the pin socket 12 near the cable tray 13. The cable tray 13 has two snap-fit ​​slots 131 corresponding to the pin socket 12. A positioning clip 1311 extends from the left end of each snap-fit ​​slot 131. The positioning clip 1311 is located in the middle of the left end of the snap-fit ​​slot 131 and is positioned along the length of the snap-fit ​​slot 131. A positioning groove 1211 is formed at the position of the positioning clip 1311 corresponding to the positioning clip 1311. The pin socket 12 enables insertion and engagement. The additionally provided cable tray 13 is detachable, facilitating the routing of other cables from the connector for operation, thus improving the functional selectivity of the connector. The positioning grooves 1211 and positioning clips 1311 cooperate to ensure a firm and stable connection between the cable tray 13 and the pin socket 12.

[0034] A cable harness tube 132 with its axis aligned along the length of the cable rack 13 is fixed on the cable rack 13. The cable harness tube 132 is positioned above the cable rack 13. A tightening tube 1321 extends from the left end of the cable harness tube 132. The inner and outer diameters of the tightening tube 1321 are both smaller than the diameter of the cable harness tube 132. An outlet 1322 is provided above the right end of the cable harness tube 132, and the connection between the outlet 1322 and the cable harness tube 132 is a rounded transition. The cable is gathered together by the tightening tube 1321 and introduced into the cable harness tube 132 before being exited through the outlet 1322, thus protecting the cable at the end and preventing breakage due to excessive bending.

[0035] A rectangular pin seat groove 122 is provided on the left side of the pin seat 12. The corners at the top and bottom of the long front side of the pin seat groove 122 are rounded. The pin seat groove 122 enables the second connector 2 to be inserted and snapped in, which facilitates the normal use of the connector. The rounded corners on the front side of the pin seat groove 122 make it easier to distinguish the front and back of the second connector 2, thereby facilitating the alignment of the pin 3 with the insertion hole 21.

[0036] Multiple connector pins 3 are provided in the pin seat groove 122. The connector pins 3 pass through the pin seat 12 and extend out of the pin seat 12. A rectangular protective shell 123 extends to the right side of the pin seat 12. The protective shell 123 is provided around the connector pins 3 and protects the connector pins 3 that extend outward.

[0037] like Figure 2 and Figure 3As shown, the second connector 2 includes a socket 22 and a connecting wire 23. The connecting wire 23 is cylindrical and located on the right side of the socket 22. The socket 22 is shaped to correspond to the pin seat groove 122. The socket 22 also has multiple insertion holes 21 corresponding to the insertion pins 3. A protective seat 231 is provided at the connection between the connecting wire 23 and the socket 22. The protective seat 231 is integrally formed with the socket 22 and surrounds the outside of the socket 22. The socket 22 and the connecting wire 23 enable the function of the second connector 2. The protective seat 231 protects the connection between the connecting wire 23 and the socket 22, extending the service life of the second connector 2.

[0038] The water-blocking component 5 includes an integrally formed connecting sleeve 51 and a waterproof sleeve 52. The connecting sleeve 51 is threadedly connected to the protective seat 231. The waterproof sleeve 52 covers the outside of the socket 22 and has a protective groove 521 in the middle to accommodate the socket 22. The shape of the waterproof sleeve 52 is similar to that of the socket 22. The waterproof sleeve 52 abuts against the surface of the first connector 1 to reduce water vapor infiltration and increase the external protection of the second connector 2. The connecting sleeve 51 and the waterproof sleeve 52 are also provided with a through opening 53. The water-blocking component 5 and the connecting line 23 are connected by the opening 53 and the thread, which can be disassembled. This can be set according to needs, and it does not affect the internal structure of the second connector 2, making it easy to remove directly later.

[0039] like Figure 2 , Figure 3 and Figure 4 As shown, locking components 6 are arranged opposite each other on the upper and lower sides of the waterproof sleeve 52. The locking components 6 include a locking plate 61, a locking clip 62, an abutment post 63, and a control shaft 64. The locking clip 62 is fixed below the locking plate 61 near the left end. The lower side of the locking clip 62 is a slope that is lower on the left and higher on the right. In the locking groove 11, on the side near the pin seat groove 122, two fixing clips 111 extend corresponding to the locking clip 62. The fixing clips 111 abut against the left and right ends of the locking clip 62.

[0040] The abutment post 63 is cylindrical and its axis is set along the width direction of the locking plate 61. The abutment post 63 is fixed to the locking plate 61 near the waterproof sleeve 52. The control shaft 64 is fixed to the side wall of the waterproof sleeve 52. The abutment post 63 is sleeved on the control shaft 64 and rotatably connected to the control shaft 64. A clamping pad 611 is also fixedly installed at the lower left end of the locking plate 61 where it connects with the waterproof sleeve 52. Under normal conditions, the locking plate 61 is set perpendicular to the waterproof sleeve 52. At this point, the locking plate 61, the clamping pad 611, and the waterproof sleeve 52 are bonded and fixed.

[0041] An elastic pad 112 is fixed inside the locking groove 11 on the side away from the pin seat groove 122. The elastic pad 112 is set along the depth direction of the locking groove 11. The side of the elastic pad 112 near the locking plate 61 is inclined, and the area of ​​the right side of the elastic pad 112 is smaller than that of the left side. The upper side of the locking plate 61 near the elastic pad 112 is also provided with an inclined surface corresponding to the elastic pad 112. The inclined surface of the elastic pad 112 cooperates with the inclined surface of the locking plate 61, so that the locking plate 61 can be smoothly inserted and locked. The inclined surface reduces friction during insertion, making it easier for the locking plate 61 to slide smoothly into the bottom, so that the locking clip 62 and the fixing clip 111 can be engaged, thereby preventing the first connector 1 and the second connector 2 from falling off.

[0042] The locking plate 61 is inserted into the locking groove 11. When it enters, the inclined surface of the locking card 62 rubs against the fixed card 111 and the locking plate 61 squeezes the elastic pad 112, thereby making the locking card 62 snap into the two fixed cards 111. Then, under the reaction force of the elastic pad 112, the locking card 62 is pressed against the locking plate 62. When unlocking and disassembling, operate and pinch one end of the two locking plates 61. With the distance of the upper locking plate 61, pinch the right end of the upper locking plate 61 and squeeze the pressing pad 611 downward. Due to the presence of the control shaft 64 and the abutment post 63, the locking plate 61 becomes a lever structure, so the left end of the locking plate 61 tilts upward and squeezes the elastic pad 112, thereby disengaging the locking card 62 from the fixed card 111. Then the locking plate 61 can be pulled out smoothly. After being pulled out, with the elasticity of the pressing pad 611, the locking plate 61 returns to its original position and is set perpendicular to the waterproof sleeve 52.

[0043] The working principle and usage of this vehicle connector device are as follows: Before use, assemble the first connector 1 by snapping the pin socket 12 with the cable tray 13, and aligning the snap-fit ​​strip 121 with the snap-fit ​​groove 131 and the positioning groove 1211 with the positioning clip 1311; then assemble the locking piece 4 on the second connector 2, and then insert the locking piece 4 and the second connector 2 together with the first connector 1 to complete the connection of the connector; when unlocking and disassembling, squeeze the locking plate 61 to compress the elastic pad 112 and then directly insert or remove the second connector 2 and the locking piece 4.
