Description

Technical Field

[0001] This utility model belongs to the field of rectangular connectors, and more specifically, relates to a rectangular connector for shielded cables. Background Technology

[0002] A rectangular connector is a connector with a rectangular interface shape, typically containing multiple contact pairs (pins / jacks) for transmitting signals, data, and power between circuits, components, or devices.

[0003] Traditional rectangular connectors typically employ locking methods such as screw fastening and snap-locking to meet the connection speed and reliability requirements of various application scenarios. However, in practical applications, screw fastening results in repetitive disassembly and low connection efficiency, while snap-locking causes severe wear on the snap-lock connection structure, leading to deformation over long-term use and inconvenience in maintenance. Therefore, we propose a rectangular connector for shielded cables to address these issues. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a rectangular connector for shielded cables.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: a rectangular connector for shielded cables, the rectangular connector including a plug and a socket, both the plug and the socket including an insulating plate, a locking member fixed on the insulating plate, the locking member including two and symmetrically arranged at both ends of the rectangular connector, each locking member including a fixed platform and a connecting platform, the fixed platform being fixedly connected to the insulating plate of the plug, the top of the fixed platform having a recessed slot, the slot being able to accommodate the fixed platform, and a guide groove being provided at one end of the inner wall along the height direction, and a locking groove being recessed on the surface of the other end, the connecting platform being fixedly connected to the insulating plate of the socket, the connecting platform being movably connected to an exposed guide post, the guide post being able to extend and retract in a direction perpendicular to the height axis of the connecting platform, the connecting platform being inserted into the top slot of the fixed platform and slidingly contacting the guide groove, when the plug and the socket are inserted, the guide post being embedded and fixed in the locking groove, the outer wall of the fixed platform having a pin hole communicating with the locking groove at the center of the corresponding locking groove.

[0006] Furthermore, the plug includes a rectangular outer shell with a hollow interior and multiple rows of first pins inserted and fixed inside. The socket includes a rectangular inner shell with multiple rows of socket holes on the top of the outer shell. Each socket hole has a second pin of the exposed socket fixed at the bottom end opposite to the inner shell. The socket holes correspond one-to-one with the first pins. The inner shell can be inserted into the hollow part of the outer shell.

[0007] Furthermore, the insulating plate is square and is respectively fitted onto the outside of the plug and the socket.

[0008] Furthermore, the guide groove is arc-shaped, and the locking groove is conical.

[0009] Furthermore, the connecting platform includes a connecting part and a mating part. The connecting part is a cuboid, and its bottom is fixedly connected to the insulating plate of the socket. The mating part includes a first truncated cone, a second truncated cone, and a spring. The first truncated cone and the second truncated cone are disposed opposite each other at the top ends of the connecting part. The bottom surfaces of the first truncated cone and the second truncated cone are both flat, and the top surfaces are smooth arc surfaces to mate with the guide groove and the locking groove, respectively. The bottom surfaces of the first truncated cone and the second truncated cone have concave connecting grooves to connect the two ends of the spring, respectively. The first truncated cone is integrally formed with the top of the connecting part and is exposed outside the connecting part. The top of the connecting part has an arc-shaped groove at the position opposite to the first truncated cone. The conical surface of the second truncated cone fits against the inner wall of the arc-shaped groove and keeps the top end exposed outside the arc-shaped groove.

[0010] Furthermore, a recessed limiting port is also opened on the conical surface of the exposed arc-shaped groove of the second truncated cone, and the limiting port can abut against the outer wall of the arc-shaped groove to limit the movement.

[0011] Furthermore, the maximum extension or retraction of the spring is not less than the depth of the locking groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention achieves a stable connection between the plug and socket by using a fixed platform that is simultaneously inserted into the slot at the top of the fixed platform during the connection process. First, the guide groove provides vertical guidance, and then the movable and telescopic guide post cooperates with the locking groove to achieve locking and fixation. This is convenient and reliable, and more efficient than traditional screw fixing. The movable and telescopic structure also avoids the hard contact method of traditional buckles.

[0015] The present invention will be further described below with reference to specific embodiments.

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the rectangular connector used for shielding the cable includes a plug 1 and a socket 2. Both the plug 1 and the socket 2 include an insulating plate 3. Specifically, the plug 1 includes a rectangular outer shell 11 with multiple rows of first pins 12 inserted and fixed inside. The socket 2 includes a rectangular inner shell 13 with multiple rows of insertion holes 14 on the top of the outer shell 11. Each insertion hole 14 has a second pin 15 of the socket 2 fixed at the end opposite to the inner shell 13. The insertion holes 14 correspond one-to-one with the first pins 12. The inner shell 13 can be inserted into the hollow part of the outer shell 11. The insulating plate 3 is square and is respectively sleeved on the outside of the plug 1 and the socket 2.

[0017] As can be seen, the connection of this connector is achieved by the mutual insertion of the plug 1 and the socket 2. During the insertion process, the inner shell 13 can be embedded in the hollow part at the top of the outer shell 11, and the first pins 12 laid inside the outer shell 11 can be inserted into the sockets 14 at the top of the outer shell 11 one by one, so as to achieve conduction with the second pins 15 set at the bottom of the sockets 14. The connection method is the conventional method of rectangular connectors, which will not be described in detail. However, in order to avoid the limitations of traditional rectangular connectors (low efficiency and high repeatability of screw tightening, deformation problem of snap locking), this utility model achieves the mutual connection of the connectors through the mutual cooperation of the connecting platform 5 and the fixing platform 4. Locking components are fixed on the insulating plate 3. The locking components include two and are symmetrically arranged at both ends of the rectangular connector. Each locking component includes a fixing platform 4 and a connecting platform 5. The fixing platform 4 is fixedly connected to the insulating plate 3 of the plug 1. The top of the fixing platform 4 has a recessed slot 6, which can accommodate the fixing platform 4. A guide groove 7 is opened at one end of the inner wall along the height direction, and a locking groove 8 is recessed on the surface of the other end. The connecting platform 5 is fixedly connected to the insulating plate 3 of the socket 2. An exposed guide post 9 is movably connected inside the connecting platform 5. The guide post 9 can be extended and retracted in a direction perpendicular to the height axis of the connecting platform 5. After the connecting platform 5 is inserted into the top slot 6 of the fixing platform 4, it slides in contact with the guide groove 7. When the plug 1 is inserted into the socket 2, the guide post 9 is embedded and fixed in the locking groove 8.

[0018] With the above structure, the connection between plug 1 and socket 2 is achieved by the fixed platform 4 being inserted into the top slot 6 of the fixed platform 4 simultaneously during the connection process. First, the guide groove 7 provides vertical guidance, and then the movable and telescopic guide post 9 and the locking groove 8 cooperate to achieve locking and fixation. This is convenient and reliable, and the connection efficiency is higher than that of traditional screw fixing. The movable and telescopic structure also avoids the hard contact method of traditional buckles. The physical deformation caused by repeated connection is small, and the long-term connection is more stable.

[0019] More specifically, regarding the telescopic fixing of the guide post 9 and the locking groove 8, in this embodiment, as follows: Figure 4 and Figure 5 As shown, the guide groove 7 is arc-shaped, and the locking groove 8 is conical. Further, the connecting platform 5 includes a connecting part 16 and a mating part 17. The connecting part 16 is a cuboid, and its bottom is fixedly connected to the insulating plate 3 of the socket 2. The mating part 17 includes a first truncated cone 19, a second truncated cone 20, and a spring 18. The first truncated cone 19 and the second truncated cone 20 are disposed opposite each other at the top ends of the connecting part 16. The bottom surfaces of the first truncated cone 19 and the second truncated cone 20 are both flat, and the top surfaces are smooth arc surfaces to mate with the guide groove 7 and the locking groove 8, respectively. The bottom surfaces of the first truncated cone 19 and the second truncated cone 20 are recessed with connecting grooves 21 to connect the two ends of the spring 18, respectively. The first truncated cone 19 is integrally formed with the top of the connecting part 16 and is exposed outside the connecting part 16. The top of the connecting part 16 has an arc-shaped groove 22 at the position opposite to the first truncated cone 19. The conical surface of the second truncated cone 20 fits against the inner wall of the arc-shaped groove 22 and keeps the top end exposed outside the arc-shaped groove 22.

[0020] After the connecting platform 5 is inserted into the slot 6 at the top of the fixing platform 4, it first contacts the inner wall of the slot 6 through the mating part 17. The contact process involves two aspects: first, the top arc surface of the first cone 19 cooperates with the arc-shaped guide groove 7 to achieve vertical guidance; second, the side arc surface of the second cone 20 contacts the inner wall of the slot 6. Due to the taper of the arc surface itself, the second cone 20 can be pushed by the corresponding taper, thereby compressing the spring 18. Then, the top arc surface of the second cone 20 makes smooth contact with the inner wall of the slot 6 and is stably guided downward through the guide groove 7. During this process, the spring 18 will continue to press the second cone 20 towards the inner wall of the slot 6 due to the reset action, until the top arc surface of the second cone 20 enters the locking groove 8. At this time, the spring 18 resets to a certain extent, realizing the mating limit between the second cone 20 and the locking groove 8. Due to the corresponding height design, the mating position is the conduction position of the first pin 12 and the second pin 15, realizing a stable connection of the connector.

[0021] Similarly, to prevent the compression of spring 18 from becoming uncontrolled, this embodiment also includes an inwardly recessed limiting port 23 on the conical surface of the exposed arcuate groove 22 of the second cone 20. The limiting port 23 can abut against the outer wall of the arcuate groove 22 to limit the compression. The maximum extension of spring 18 is not less than the depth of the locking groove 8.

[0022] If you want to disconnect the socket 2 from the plug 1 later, you can do so through the pin hole 10 on the outer wall of the fixed platform 4. The position of the pin hole 10 corresponds to the center of the locking groove 8. You can apply external force by using the matching pin to compress the spring 18 and separate the second cone 20 from the locking groove 8. Then you can pull out the plug 1. Similarly, the matching pin can be designed to be made of rubber and integrally connected to the outer wall of the fixed platform 4 for convenience and reliability.

[0023] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
