Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a connector that is easy to assemble. Background Art

[0002] Plug-in connectors (connectors for short) are the core components for achieving electrical connections in automotive circuits. Circuit conduction is completed through the mechanical insertion of plugs and sockets. They mainly establish electrical connections through metal terminals (such as copper alloy pins / sockets) and support DC / AC current transmission.

[0003] As electronic devices continue to evolve, connectors, as key components for circuit connectivity and signal transmission, have a significant impact on the stability and reliability of the entire electronic system. As electronic products evolve towards miniaturization, higher performance, and greater multifunctionality, connectors are increasingly demanding, requiring not only excellent electrical performance but also the ability to adapt to complex operating environments and frequent plugging and unplugging. This has driven the industry to continuously explore and improve connector design and manufacturing technologies to meet growing market demand. Connectors are also widely used in numerous fields, including automotive, aerospace, and industrial automation, and advances in connector technology are crucial for driving development in these sectors.

[0004] When assembling traditional connectors, the connection method between the terminals and the housing is relatively complicated, usually using welding or screw fastening methods. The welding process requires professional equipment and skilled workers to operate, which not only increases production costs, but also makes the welding points prone to problems such as cold soldering and desoldering, affecting the electrical performance and stability of the connector. Screw fastening requires frequent tightening and loosening of screws, which is cumbersome and time-consuming, and is not conducive to large-scale production and rapid assembly. When connecting the connector to the socket, it generally relies on simple plug-in and pull-out matching, lacking effective fixing measures, which can easily cause the connector to loosen or fall off during use, thereby affecting the normal connection of the circuit and signal transmission. In addition, traditional connectors have poor compatibility with different types of terminals and can often only connect to a single type of terminal, making it difficult to meet diverse application requirements.

[0005] These shortcomings of existing technologies lead to low connector assembly efficiency, increased labor and time costs, and are prone to problems such as poor contact and looseness during use, affecting the normal operation of electronic equipment. The limitations of traditional connectors are particularly evident in areas where high stability and reliability are required. Summary of the Invention

After being installed in place, the anti-fool bar extends into the anti-fool groove, and the anti-fool block abuts against the third limit bar 14.

[0057] Reference Figure 2 、 Figure 5 , a snap-in slot 15 is provided on the housing 1, and two first limiting strips 12 are fixedly connected to the inner wall of the snap-in slot 15, and the first limiting strips 12 cooperate with the inner wall of the snap-in slot 15 to form a limiting slot. In addition, a snap-in hole is provided on the inner wall of the snap-in slot 15, and a snap-in member 16 is fixedly connected to the outer wall of the snap-in plate 201 away from the first plug-in block 202, and the snap-in member 16 extends into the snap-in hole so that the terminal block 2 is snap-connected to the housing 1. When the housing 1 is snap-connected to the terminal block 2, the snap-in plate 201 is inserted into the corresponding limiting slot. At the same time, a plug-in hole 17 adapted to the first terminal and the second terminal is provided in the snap-in slot 15, so that an external plug can pass through the corresponding plug-in hole 17 to communicate with the first terminal or the second terminal. At the same time, an anti-accidental touch plate 18 is fixedly connected to the housing 1 at the connection with the terminal block 2 to prevent the terminal block 2 from being disengaged from the housing 1 during normal use.

[0058] The first fixing component 3 includes a rotating rod 301 in a "C" shape. Both ends of the rotating rod 301 are provided with rotating shafts 302 fixedly connected to the surface of the housing 1. The rotating rod 301 rotates on the surface of the housing 1 with the rotating shaft 302 as the center. And, two clamping blocks 303 are fixedly connected to the two ends of the rotating rod 301 near the rotating shaft 302. After the housing 1 and the socket are installed in place and the rotating rod 301 rotates, the two clamping blocks 303 cooperate to snap-fix the housing 1 and the socket.

[0059] A wire bundling plate 304 is fixedly connected to the side of the housing 1 away from the insertion hole 17. The wire bundling plate 304 is smoothly transitioned with the surface of the housing 1. At the same time, a wire bundling groove communicating with the clamping groove 15 is provided in the wire bundling plate 304. After the terminal block 2 is installed in place and the terminal block 2 is snap-fixed to the housing 1, the wires on the terminal block 2 are pressed against the inner wall of the wire bundling groove, thereby controlling the extending direction of the wires.

[0060] Refer to Figure 2 、 Figure 6 The wire bundling plate 304 is provided with an arc surface, and a relief hole is provided in the arc surface. An elastic plate 305 is fixedly connected to the side wall of the relief hole. A limiting block 306 is fixedly connected to the surface of the elastic plate 305 on the side outside the wire bundling groove. In addition, convex strips 307 are fixedly connected to the edges of the wire bundling plate 304 and the housing 1. The convex strips 307 are fixedly connected to the anti-misoperation plate 18. At the same time, a clamping plate is fixedly connected to the inner wall of the wire bundling groove, and the clamping plate is used to limit the bending radian of the elastic plate 305 towards the inside of the wire bundling groove.

[0061] The side of the cross bar of the rotating rod 301 close to the housing 1 is set as an inclined surface, and the inclined surface is matched with the side of the limiting block 306 away from the housing 1. When the rotating rod 30l rotates to the position of the limiting block 306, the cross bar of the rotating rod 301 can press the limiting block 306, thereby pushing the limiting block 306 to slide into the wire bundling groove. When the rotating rod 301 further rotates and is located between the limiting block 306 and the convex strip 307, the housing 1 and the socket are snap-fixed, and, the side surface of the limiting block 306 abuts against the surface of the cross bar of the rotating rod 301, and the limiting block 306 and the convex strip 307 cooperate to limit the position of the rotating rod 301.

[0062] Refer to Figure 5 ,Three insertion strips 19 are fixedly connected to the positions of the two opposite side walls of the housing 1 close to the insertion hole 17, and the positions of the insertion strips 19 on the two sides on the housing 1 do not correspond to each other. In this way, when the housing 1 is inserted into the socket, the insertion strips 19 have an anti-fooling function, and at the same time, the insertion strips 19 abut against the inside of the socket, thereby increasing the stability after the housing 1 is inserted.

[0063] Refer to Figure 2 、 Figure 5 、 Figure 6. The two opposite side walls of the housing 1 are fixedly connected with a locking protrusion 308, which is provided with a rounded corner portion, and the side away from the rounded corner portion is provided with an inclined surface. When the housing 1 is not fixed to the socket buckle, the rotating rod 301 abuts against the insertion strip 19 and the locking protrusion 308 to limit the position of the rotating rod 301 to prevent the rotating rod 301 from rotating during transportation and causing wear on the rotating shaft 302. It should be noted that at this time, the rounded corner portion of the locking protrusion 308 abuts against the rotating rod 301. In addition, a sliding groove is provided on the inner wall of the rotating rod 301, and the inner wall of the sliding groove is inclined. When the rotating rod 301 is reset, the inner wall of the sliding groove abuts against the inclined surface on the locking protrusion 308.

[0064] The implementation principle of Example 1 of the present application is as follows: by means of a snap connection between the terminal block 2 and the housing 1, the speed at which the connector is assembled by the staff can be facilitated, wherein the terminal block 2 is installed with a first terminal by means of a first plug-in block 202 fixedly connected to itself, and the terminal block 2 is installed with a second plug-in block 203 snap-in connected to itself, and the first terminal and the second terminal are two different types of terminals, so that the terminal block 2 can be connected to two different types of terminals, thereby increasing the functionality of the connector after connection. In addition, when the terminal block 2 is connected to the housing 1, the cooperation between the snap-in plate 201 and the first limit strip 12 can prevent the terminal block 2 from being incorrectly connected to the housing 1.

[0065] After the first terminal is connected to the first plug-in block 202, the first terminal is locked to the first plug-in block 202 by the cooperation of the locking piece 6 and the locking rod 7, so as to prevent the first terminal from being detached from the first plug-in block 202 during normal use of the terminal block 2. At the same time, when connecting the second plug-in block 203, the guide rod 10, the second limiting strip 13, and the third limiting strip 14 can prevent the second plug-in block 203 from being incorrectly connected. Moreover, the guide rod 10 is inserted into the second plug-in block 203 to lock the second terminal to the second plug-in block 203, so as to prevent the second terminal from being detached from the second plug-in block 203 during normal use of the terminal block 2.

[0066] Once the terminal block 2 is properly connected to the housing 1, the wire tie plate 304 controls the direction of the wires connected to the terminals, preventing them from becoming tangled and making it easier for the operator to insert the housing 1 into the socket. When inserting the housing 1 into the socket, the operator can align the insertion bar 19 with the socket to calibrate the insertion position of the housing 1. Furthermore, the fit of the insertion bar 19 with the socket effectively increases the stability of the housing 1.

[0067] After the housing 1 is properly inserted into the socket, the operator can rotate the rotating rod 301, which is made of plastic. When the rotating rod 301 is pressed against the latching protrusion 308, the rotating rod 301 deforms, allowing the latching protrusion 308 to extend into the sliding groove. Further rotation of the rotating rod 301 causes the two engaging blocks 303 to engage with the blocks on the socket, thus securing the housing 1 to the socket. When the housing 1 is removed from the socket, the operator can press the limit block 306, causing it to extend into the cable trough and simultaneously drive the rotating rod 301 to reset. At this time, the engaging blocks 303 disengage from the blocks on the socket. Example

[0069] The second fixing assembly 4 includes two sets of curved blocks, each of which is positioned on the surface of the two connecting blocks 20 away from the anti-inadvertent touch plate 18. Each set of curved blocks includes a first curved block 401 and a second curved block 402, with the first curved block 401 positioned on the edge of the connecting block 20 near the housing 1. Furthermore, when the rotating rod 301 is in its initial position, the first curved block 401 and the second curved block 402 are positioned between the rotating rod 301 and the connecting block 20. A rotational clearance is provided between the rotating rod 301 and the first and second curved blocks 401, 402 to prevent friction between the rotating rod 301 and the surfaces of the first and second curved blocks 401, 402 during rotation.

[0070] Reference Figure 7 、 Figure 8 、 Figure 9 The connecting block 20 includes a connecting groove 21 that communicates with the engaging groove 15. Second rotation grooves are defined on the inner walls of the connecting groove 21 on opposite sides. Furthermore, a second arcuate groove is defined on the second arcuate block 402, which communicates with the connecting groove 21. A vibration damping plate 403 is slidably connected to the inner wall of the second arcuate groove. A second clamping post is fixedly connected to the end of the vibration damping plate 403 facing away from the second arcuate block 402. The second clamping post is inserted into the second rotation groove, allowing the vibration damping plate 403 to rotate along the inner wall of the second arcuate groove, centered around the second clamping post. After the vibration damping plate 403 is installed, it is tilted relative to the sidewalls of the connecting groove 21, and the vibration damping plate 403 cooperates with the bottom of the connecting groove 21 to form a vibration damping cavity.

[0071] The damping plate 403 is fixedly connected with a locking spring 404 located in the damping cavity. One side of the locking spring 404 away from the damping plate 403 is fixedly connected with a blocking block 405. In addition, a through hole for the blocking block 405 to pass through is provided on the connecting block 20. Among them, when the rotating rod 301 is in the initial position, the blocking block 405抵触 the rotating rod 301 after passing through the through hole; when the rotating rod 301 rotates and the outer shell 1 is snap-connected with the socket, the locking spring 404 pushes the blocking block 405 to extend into the socket, so that the blocking block 405 is inserted into the socket.

[0072] A first rotating groove is provided in the connecting groove 21, and the first rotating groove is located between the second rotating groove and the clamping groove 15. A first arc groove communicating with the connecting groove 21 is provided on the first arc block 401. The inner wall of the first arc groove is slidably connected with a plugging plate 406 arranged parallel to the damping plate 403. One side of the plugging plate 406 away from the first arc block 401 is fixedly connected with a first clamping column. The first clamping column is inserted into the first rotating groove, so that the plugging plate 406 can rotate along the inner wall of the first arc groove with the first clamping column as the center. In addition, a "C"-shaped elastic sheet cover 407 is connected between the plugging plate 406 and the first clamping column. One end of the elastic sheet cover 407 is rotatably connected with the plugging plate

[0073] A让位槽 22 is provided on the plugging plate 406, and a first elastic sheet 408 is embedded between the inner walls of the first arc block 401 and the让位槽 22 of the plugging plate 4 The first elastic sheet 408 includes a bending section 4081, a locking section 4082, and a damping section 4083, where the bending section 4081 is embedded in the plugging plate 406, the locking section 4082 is fixedly connected to both ends of the bending section 4081靠近 the terminal block 2, and the damping section 4083 is fixedly connected to the middle of the bending section 4081靠近 the damping plate 403, so that the damping section 4083 and the locking section 4082 are arranged in a staggered manner. In addition, both the locking section 4082 and the damping section 4083 are arranged in a wavy shape, and the orientation of the wavy bending part of the locking section 4082 is opposite to the orientation of the wavy bending part of the damping section 4083.

[0074] It should be noted that there are some unclear or incomplete expressions in the original text, such as "抵触" in which may need further clarification to ensure more accurate translation. Also, "让位槽 22" in is not clear what it exactly means in Chinese, and the translation is a bit tentative.A third spring clip 410 is fixedly connected to the side of the snap-in plate 201 near the plug-in plate 406. The third spring clip 410 is an elastic plastic sheet. The end of the third spring clip 410 away from the first curved block 401 is bent toward the spring clip cover 407. Furthermore, a fixing buckle 411 is fixedly connected to the spring clip cover 407. The third spring clip 410 extends into the fixing buckle 411 and is fixed thereto. Furthermore, the third spring clip 410 is provided with a spring clip slot 23. The inner wall of the spring clip slot 23 away from the fixing buckle 411 is fixedly connected to the second spring clip 409. The other end of the second spring clip 409 is fixedly connected to the inner wall of the spring clip slot 23 near the fixing buckle 411. Among them, the second spring piece 409 is set to be wavy, and the direction of the wavy curved part of the second spring piece 409 is consistent with the direction of the wavy curved part of the locking section 4082. After being installed in place, the second spring piece 409 conflicts with the locking section 4082 of the first spring piece 408, and the wavy curved part of the second spring piece 409 conflicts with the wavy curved part of the vibration-damping section 4083 of the first spring piece 408.

[0075] The implementation principle of Example 2 of the present application is as follows: during assembly, one end of the vibration damping plate 403 is first inserted obliquely into the inner wall of the second arc-shaped groove, and then the second clamping column is inserted into the second rotating groove, so that the through hole of the abutment block 405 contacts the rotating rod 301. Subsequently, the plug-in board 406 is assembled with the first elastic piece 408, and then one end of the plug-in board 406 is inserted obliquely into the inner wall of the first arc-shaped groove, and then the first clamping column is inserted into the first rotating groove, so that the plug-in board 406 is parallel to the vibration damping plate 403, and at the same time, the vibration damping section 4083 of the first elastic piece 408 is between the plug-in board 406 and the vibration damping plate 403, and the vibration damping section 4083 of the first elastic piece 408 contacts the vibration damping plate 403, and the plug-in board 406 is fixed to the connecting block 20 by the elastic piece cover 407.

[0076] The assembled terminal block 2 is installed on the housing 1 through the snap-in slot 15. At this time, the second spring piece 409 slides along the surface of the first spring piece 408. During the installation of the terminal block 2, the second spring piece 409 and the third spring piece 410 gradually push the plug-in board 406 and the vibration-damping plate 403 to slide away from the terminal block 2, causing the locking spring 404 to deform and compress. When the locking spring 404 cannot deform and compress, the first spring piece 408 deforms and extends. When the terminal block 2 is inserted, the third spring piece 410 is fixed to the connecting block 20, the first spring piece 408 contacts the second spring piece 409, and the vibration-damping section 4083 of the first spring piece 408 is slightly longer than the locking section 4082 of the first spring piece 408 due to elastic deformation.

[0077] At this time, the locking section 4082 of the first spring piece 408 fits against the second spring piece 409, and the vibration-damping section 4083 of the first spring piece 408 contacts the second spring piece 409, thereby locking the terminal block 2 to the housing 1. In addition, the first spring piece 408 applies lateral elastic pressure to the terminal block 2 through the vibration-damping section 4083, and applies longitudinal elastic pressure to the terminal block 2 through the locking section 4082. When the terminal block 2 is subjected to a lateral or longitudinal impact force, the impact force on the terminal block 2 can be reduced by the deformation of the vibration-damping section 4083 of the first spring piece 408 or the locking section 4082 of the first spring piece 408.

[0078] In addition, when the shell 1 is connected to the socket buckle and the rotating rod 301 is rotated, the locking spring 404 is deformed and elongated, and the stop block 405 is pushed out and inserted into the socket. At the same time, the elastic force acting on the vibration damping plate 403 and the first spring piece 408 decreases, and the vibration damping plate 403 can slide further, thereby providing deformation space for the first spring piece 408, thereby increasing the vibration damping ability of the connector when in use.

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
