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 develop, connectors are key components for circuit connection and signal transmission. Their performance and quality directly affect the stability and reliability of the entire electronic system. As electronic products develop towards miniaturization, high performance and multi-functionality, the requirements for connectors are getting higher and higher. They not only need to have good electrical performance, but also need to be able to adapt to complex usage environments and frequent plug-in and unplug operations. This has prompted the industry to continuously explore and improve the design and manufacturing technology of connectors to meet the growing market demand. At the same time, connectors are also widely used in many fields such as automobiles, aerospace, and industrial automation. The advancement of their technology is of great significance to promoting the development of these fields.

[0004] When assembling traditional connectors, the connection method between the terminal and the shell is relatively complicated, usually by welding or screw fastening. The welding process requires professional equipment and skilled workers to operate, which not only increases production costs, but also makes it easy for welding points to have 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 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 defects of the prior art lead to low efficiency of connector assembly, increased labor costs and time costs, and problems such as poor contact and looseness are prone to occur during use, affecting the normal operation of electronic equipment. In particular, in some fields with high requirements for stability and reliability, the limitations of traditional connectors are more obvious. Summary of the invention

In addition, side wall grooves are provided on the opposite inner walls on both sides of the groove. After the locking piece 6 is installed in place, the staff can take out the locking piece 6 through the side wall grooves. Three locking rods 7 are integrally connected to the locking piece 6, and each locking rod 7 is correspondingly inserted into a locking channel. In addition, a clamping groove is provided on the clamping plate 201, and a convex block 8 is fixedly connected to the locking rod 7 on the locking piece 6 close to the clamping plate 201, and the convex block 8 extends into the clamping groove, thereby making the locking rod 7 and the clamping plate 201 snap-fitted and fixed. After the locking rod 7 is installed in place, the locking rod 7 abuts against the first terminal, thereby locking the first terminal.

[0033] Refer to Figure 3 , the two clamping plates 201 and the first insertion block 202 cooperate to form an installation groove 9. In addition, three guide rods 10 extending into the installation groove 9 are fixedly connected to the side wall of the first insertion block 202, and two of the guide rods 10 are fixedly connected to the inner wall of the installation groove 9. In addition, a second insertion block 203 is inserted into the installation groove 9, and the second insertion block 203 and the clamping plate 201 are detachably connected by a snap connection. Three rows of second insertion slot rows arranged horizontally between the two clamping plates 201 are provided in the second insertion block 203, and seven second insertion slots 11 arranged along the length direction of the clamping plate 201 are provided in each row of second insertion slot rows.

[0034] Refer to Figure 3 , Figure 4, a guiding groove is formed in the side wall of the second plugging block 203, and two adjacent guiding grooves communicate with each other, thereby forming three guiding channels in the second plugging block 203. The guiding rods 10 are respectively inserted into the corresponding guiding channels, and the guiding rods 10 are in contact with the second terminals, thereby locking the second terminals. In addition, two second limiting strips 13 and two third limiting strips 14 are fixedly connected to the inner wall of the installation groove 9. Among them, the second limiting strip 13 and the inner wall of the installation groove 9 cooperate to form an anti-fooling groove. An anti-fooling strip is fixedly connected to the second plugging block 203, and an anti-fooling block is fixedly connected to the second plugging block 203. After being installed in place, the anti-fooling strip extends into the anti-fooling groove, and the anti-fooling block is in contact with the third limiting strip 14.

[0035] Refer to Figure 2 , Figure 5 , a clamping groove 15 is formed in the outer shell 1, and two first limiting strips 12 are fixedly connected to the inner wall of the clamping groove 15. The first limiting strip 12 and the inner wall of the clamping groove 15 cooperate to form a limiting groove. In addition, a clamping hole is formed in the inner wall of the clamping groove 15, and a clamping member 16 is fixedly connected to the outer wall of the clamping plate 201 far away from the first plugging block 202. The clamping member 16 extends into the clamping hole, thereby enabling the terminal seat 2 to be snap-connected to the outer shell 1. When the outer shell 1 is snap-connected to the terminal seat 2, the clamping plate 201 is inserted into the corresponding limiting groove. At the same time, a plugging hole 17 adapted to the first terminal and the second terminal is formed in the clamping groove 15, so that an external plug can pass through the corresponding plugging hole 17 to communicate with the first terminal or the second terminal. At the same time, an anti-misoperation plate 18 is fixedly connected to the connection part of the outer shell 1 and the terminal seat 2 to prevent the terminal seat 2 from being disengaged from the outer shell 1 during normal use of the outer shell 1.

[0036] 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 outer shell 1. The rotating rod 301 rotates on the surface of the outer shell 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 close to the rotating shaft 302. After the outer shell 1 and the socket are installed in place and the rotating rod 301 rotates, the two clamping blocks 303 cooperate to snap-fix the outer shell 1 and the socket.

[0037] A wire bundling plate 304 is fixedly connected to one side of the outer shell 1 far away from the plugging hole 17. The wire bundling plate 304 is smoothly transitioned with the surface of the outer shell 1. At the same time, a wire bundling groove communicating with the clamping groove 15 is arranged in the wire bundling plate 304. After the terminal seat 2 is installed in place and the terminal seat 2 is snap-fixed to the outer shell 1, the wires on the terminal seat 2 are pressed against the inner wall of the wire bundling groove, thereby controlling the extending direction of the wires.

[0038] Refer to Figure 2 , Figure 6, the wire bundling plate 304 is provided with an arc surface, and a relief hole is formed 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 both the wire bundling plate 304 and the outer shell 1, and 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.

[0039] The side of the cross bar of the rotating rod 301 close to the outer shell 1 is set as an inclined surface, and this inclined surface is matched with the side of the limiting block 306 away from the outer shell 1, so that when the rotating rod 301 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 towards the inside of 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 outer shell 1 is fixedly buckled with the socket, 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.

[0040] Refer to Figure 5 , three insertion strips 19 are fixedly connected to both opposite side walls of the outer shell 1 close to the insertion hole 17, and the positions of the insertion strips 19 on both sides on the outer shell 1 do not correspond to each other, so that when the outer shell 1 is inserted into the socket, the insertion strips 19 have an anti-fooling function, and at the same time, the insertion strips 19 are in contact with the inside of the socket, thereby increasing the stability after the outer shell 1 is inserted.

[0041] Refer to Figure 2 、 Figure 5 、 Figure 6 . The outer shell 1 is fixedly connected with a clamping convex 308 on two opposite side walls. The clamping convex 308 is provided with a rounded corner part, and the side away from the rounded corner part is set as an inclined surface. When the outer shell 1 is not fixedly buckled with the socket, the rotating rod 301 abuts against the insertion strip 19 and the clamping convex 308 to limit the position of the rotating rod 301 to prevent the rotating rod 301 from rotating during transportation and causing wear to the rotating shaft 302. It should be noted that at this time, the rounded corner part of the clamping convex 308 abuts against the rotating rod 301. In addition, a sliding groove is formed in 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 clamping convex 308.

[0042] The implementation principle of Embodiment 1 of this application is as follows: By the snap connection between the terminal block 2 and the housing 1, the assembly speed of the connector can be facilitated for the staff. Among them, the first terminal is installed on the terminal block 2 through the first insertion block 202 fixedly connected to itself, and the second terminal is installed on the terminal block 2 through the second insertion block 203 snap-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 functions after the connector is connected. In addition, when the terminal block 2 is connected to the housing 1, through the cooperation of the clamping plate 201 and the first limiting strip 12, the wrong connection between the terminal block 2 and the housing 1 can be avoided.

[0043] After the first terminal is connected to the first insertion block 202, the first terminal and the first insertion block 202 are locked through the cooperation of the locking piece 6 and the locking rod 7 to prevent the first terminal from detaching from the first insertion block 202 when the terminal block 2 is in normal use. At the same time, when connecting the second insertion block 203, the wrong connection of the second insertion block 203 can be avoided through the guide rod 10, the second limiting strip 13, and the third limiting strip 14. And, by inserting the guide rod 10 into the second insertion block 203, the second terminal is locked to the second insertion block 203 to prevent the second terminal from detaching from the second insertion block 203 when the terminal block 2 is in normal use.

[0044] After the terminal block 2 is correctly connected to the housing 1, the wire bundling plate 304 can control the direction of the wire connected to the terminal, thereby preventing the wire from being scattered and reducing the connection difficulty when the staff inserts the housing 1 into the socket. When inserting the housing 1 into the socket, the staff can align the housing 1 with the socket through the insertion strip 19, thereby calibrating the insertion position of the housing 1. At the same time, the cooperation between the insertion strip 19 and the socket can effectively increase the stability of the housing 1.

[0045] After the housing 1 is correctly inserted into the socket, the staff can drive the rotating rod 301 to rotate. And the rotating rod 301 is made of plastic material. When the rotating rod 301 is squeezed by the convex 308, the rotating rod 301 is deformed so that the convex 308 extends into the sliding groove. The further rotation of the rotating rod 301 causes the two clamping blocks 303 to cooperate with the blocks on the socket, thereby snap-fixing the housing 1 to the socket. When the housing 1 is pulled out of the socket, the staff can press the limiting block 306 so that the limiting block 306 extends into the wire slot and at the same time drives the rotating rod 301 to reset. At this time, the clamping block 303 is disengaged from the block on the socket. Embodiment

The rotating rod 301 is rotatably connected to the surface of the connecting block 20 through a rotating shaft 302.

[0047] The second fixing component 4 includes two groups of arc-shaped block groups, and the two groups of arc-shaped block groups are respectively arranged on the surfaces of the two connecting blocks 20 away from the anti-misoperation plate 18. Among them, each group of arc-shaped block groups includes a first arc-shaped block 401 and a second arc-shaped block 402, and the first arc-shaped block 401 is arranged at the edge of the connecting block 20 close to the outer shell 1. In addition, when the rotating rod 301 is in the initial position, the first arc-shaped block 401 and the second arc-shaped block 402 are located between the rotating rod 301 and the connecting block 20. At the same time, a rotating gap is provided between the rotating rod 301 and the first arc-shaped block 401 and the second arc-shaped block 402 to prevent the surface of the rotating rod 301 from rubbing against the surface of the first arc-shaped block 401 or the second arc-shaped block 402 during rotation.

[0048] Refer to Figure 7 , Figure 8 , Figure 9 , a connecting groove 21 communicating with the clamping groove 15 is opened in the connecting block 20, second rotating grooves are opened on the inner walls of the opposite sides of the connecting groove 21, and in addition, a second arc-shaped groove communicating with the connecting groove 21 is opened on the second arc-shaped block 402. A damping plate 403 is slidably connected to the inner wall of the second arc-shaped groove, and a second clamping column is fixedly connected to one end of the damping plate 403 away from the second arc-shaped block 402. The second clamping column is inserted into the second rotating groove, so that the damping plate 403 can rotate along the inner wall of the second arc-shaped groove with the second clamping column as the center. After the damping plate 403 is installed in place, the damping plate 403 is inclined with respect to the side wall of the connecting groove 21, and the damping plate 403 and the bottom of the connecting groove 21 cooperate to form a damping cavity.

[0049] A locking spring 404 located in the damping cavity is fixedly connected to the damping plate 403, a resisting block 405 is fixedly connected to the side of the locking spring 404 away from the damping plate 403, and in addition, a through hole for the resisting block 405 to pass through is opened on the connecting block 20. Among them, when the rotating rod 301 is in the initial position, the resisting block 405 passes through the through hole and abuts against the rotating rod 301; when the rotating rod 301 rotates and the outer shell 1 is snap-connected to the socket, the locking spring 404 pushes the resisting block 405 into the socket, so that the resisting block 405 is inserted into the socket.

[0050] A first rotation groove is formed in the connection groove 21, and the first rotation groove is located between the second rotation groove and the clamping groove 15. A first arc groove communicating with the connection groove 21 is formed in the first arc block 401. A plugging plate 406 arranged parallel to the damping plate 403 is slidably connected to the inner wall of the first arc groove. A first clamping column is fixedly connected to the side of the plugging plate 406 away from the first arc block 401. The first clamping column is inserted into the first rotation 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, an "L"-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 to the plugging plate 406, and a fixing groove is fixedly connected to the other end of the elastic sheet cover 407. At the same time, a fixing block is fixedly connected to the connection block 20. After the elastic sheet cover 407 rotates along the first clamping column, the fixing groove is clamped with the fixing block, and at this time, the elastic sheet cover 407 abuts against the connection block 20.

[0051] A relief groove 22 is formed in the plugging plate 406, and a first elastic sheet 408 is embedded between the inner walls of the first arc block 401 and the relief groove 22 of the plugging plate 406. The first elastic sheet 408 includes a bent section 4081, a locking section 4082, and a damping section 4083. The bent section 4081 is embedded in the plugging plate 406. The locking section 4082 is fixedly connected to both ends of the bent section 4081 close to the terminal block 2. The damping section 4083 is fixedly connected to the middle of the bent section 4081 close to 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 wave shape, and the orientations of the wave bending parts of the locking section 4082 and the damping section 4083 are opposite.

[0052] A third elastic sheet 410 is fixedly connected to the side of the clamping plate 201 close to the plugging plate 406. The third elastic sheet 410 is an elastic plastic sheet. The end of the third elastic sheet 410 away from the first arc block 401 bends towards the elastic sheet cover 407. In addition, a fixing buckle 411 is fixedly connected to the elastic sheet cover 407. The third elastic sheet 410 extends into the fixing buckle 411 and is snap-fixed with the fixing buckle 411. And, a elastic sheet groove 23 is formed in the third elastic sheet 410. A second elastic sheet 409 is fixedly connected to the inner wall of the elastic sheet groove 23 away from the fixing buckle 411, and the other end of the second elastic sheet 409 is fixedly connected to the inner wall of the elastic sheet groove 23 close to the fixing buckle 411. Among them, the second elastic sheet 409 is arranged in a wave shape, and the orientation of the wave bending part of the second elastic sheet 409 is the same as that of the wave bending part of the locking section 4082 of the first elastic sheet 408. After being installed in place, the second elastic sheet 409 abuts against the locking section 4082 of the first elastic sheet 408, and the wave bending part of the second elastic sheet 409 abuts against the wave bending part of the damping section 4083 of the first elastic sheet 408.

[0053] The implementation principle of Embodiment 2 of this application is as follows: During assembly, first, one end of the damping plate 403 is inserted obliquely into the inner wall of the second arc-shaped groove, then the second clamping post is inserted into the second rotating groove, and the abutting block 405 passes through the through hole and abuts against the rotating rod 301. Subsequently, the plugging plate 406 and the first elastic piece 408 are assembled. Then, one end of the plugging plate 406 is inserted obliquely into the inner wall of the first arc-shaped groove, and the first clamping post is inserted into the first rotating groove, and the plugging plate 406 is parallel to the damping plate 403. At the same time, the damping section 4083 of the first elastic piece 408 is between the plugging plate 406 and the damping plate 403, and the damping section 4083 of the first elastic piece 408 abuts against the damping plate 403, and the plugging plate 406 and the connecting block 20 are snap-fixed by the elastic piece cover 407.

[0054] The assembled terminal block 2 is installed with the housing 1 from the clamping groove 15. At this time, the second elastic piece 409 slides along the surface of the first elastic piece 408. And during the installation process of the terminal block 2, the second elastic piece 409 and the third elastic piece 410 gradually push the plugging plate 406 and the damping plate 403 to slide away from the terminal block 2, and the locking spring 404 deforms and compresses. When the locking spring 404 cannot deform and compress, the first elastic piece 408 deforms and elongates. When the insertion of the terminal block 2 is completed, the third elastic piece 410 and the connecting block 20 are snap-fixed, the first elastic piece 408 abuts against the second elastic piece 409, and at this time, the damping section 4083 of the first elastic piece 408 will be slightly longer than the locking section 4082 of the first elastic piece 408 due to elastic deformation.

[0055] At this time, the locking section 4082 of the first elastic piece 408 fits with the second elastic piece 409, and the damping section 4083 of the first elastic piece 408 abuts against the second elastic piece 409, and thereby the terminal block 2 and the housing 1 are locked. In addition, the first elastic piece 408 exerts a lateral elastic pressure on the terminal block 2 through the damping section 4083 and a longitudinal elastic pressure on 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 received by the terminal block 2 can be weakened through the deformation of the damping section 4083 or the locking section 4082 of the first elastic piece 408.

[0056] In addition, when the housing 1 is snap-connected to the socket and the rotating rod 301 is rotated, the locking spring 404 deforms and elongates, and the abutting block 405 is pushed out and inserted into the socket. At the same time, the elastic forces received by the damping plate 403 and the first elastic piece 408 decrease, and at the same time, the damping plate 403 can further slide, thereby providing a deformation space for the first elastic piece 408, so as to increase the damping capacity of the connector during use.

Identical components are denoted by the same reference numerals.
