Abstract
Description
Technical Field
[0001] This utility model relates to the field of coupler technology, specifically to a coupler. Background Technology
[0002] Chinese Patent Publication No. CN222338562U discloses a coupler assembly, including an upper coupler and a lower coupler that cooperate with each other. The bottom of the upper coupler housing is recessed upward to form a receiving cavity. A first row of pins and a second row of pins are arranged in the receiving cavity. The number of pins in the first row of pins is greater than the number of pins in the second row of pins. The pins of the two rows of pins are staggered to form a trapezoidal structure. The wires connected to the pins of the second row of pins can pass through the gaps between the pins of the first row of pins and then extend out of the upper coupler housing on one side of the first row of pins together with the wires connected to the pins of the first row of pins. This allows the wires connected to the pins of the second row of pins to connect to the electronic devices on the side of the first row of pins without bending, avoiding wire compression and clamping phenomena that are prone to occur at the bending part of the wires during coupler installation. Without bending the wires, the probability of wire damage is reduced and the service life of the wires is improved.
[0003] In the aforementioned patent, the pins are not isolated from each other, resulting in multiple sets of pins being in a large space. Since the pins are thin and have low strength, they are easily damaged by external forces (such as bending, deformation, or mismatch between the spacing and the socket). Pins that are in the same large space are more likely to be damaged by external objects, and in most cases, multiple sets are damaged at the same time. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A coupler includes an upper coupling member and a lower coupling member, wherein the upper coupling member and the lower coupling member are plugged into each other, and the lower coupling member is provided with a plurality of pins electrically connected to the upper coupling member, wherein the plurality of pins are separated into different receiving cavities by an isolation protective plate.
[0007] Preferably, a limiting platform is provided at the lower end of the lower coupling member.
[0008] Preferably, a second terminal block is fixedly connected to the limiting platform, and the second terminal block is electrically connected to the pin.
[0009] Preferably, the upper coupling member is provided with a plurality of contact end sleeves, and both the upper coupling member and the contact end sleeves are fixedly connected to the terminal fixing base, with the upper coupling member sleeved outside the contact end sleeves.
[0010] Preferably, a space is provided between the plurality of contact end sleeves to accommodate the isolation and protective plate.
[0011] Preferably, the contact end sleeve is provided with a socket for inserting a pin.
[0012] Preferably, a first wiring terminal is fixedly connected to the terminal holder.
[0013] Preferably, a spring contact assembly is provided in the socket, the spring contact assembly is used to contact the pin, and the spring contact assembly is electrically connected to the first terminal block.
[0014] Preferably, the spring assembly includes a fixing plate, an elastic plate, and a pressure plate. The fixing plate and the pressure plate are arranged in parallel. The fixing plate is fixedly connected to the inner wall of the socket. The fixing plate and the pressure plate are connected by an elastic plate. The elastic plate is arc-shaped in its natural state.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:
[0017] This application provides an isolation and protective plate around the pin, which creates a small space between the isolation and protective plate and the edge of the lower coupling member to accommodate the pin. This makes it difficult for foreign objects to enter this space and damage the pin. Even if damage occurs in individual cases, it is highly likely to be limited to a single group of pins, and it is unlikely to cause widespread damage. Attached Figure Description

[0025] Example 1
[0026] Please see Figures 1-3 The present invention provides an embodiment of a coupler, comprising an upper coupling member 1 and a lower coupling member 2, wherein the upper coupling member 1 and the lower coupling member 2 are plugged into each other, and the lower coupling member 2 is provided with a plurality of pins 10 electrically connected to the upper coupling member 1, wherein the plurality of pins 10 are separated into different receiving cavities 8 by an isolation protective plate 9.
[0027] The lower coupling member 2 is provided with a limiting platform 6 at its lower end.
[0028] A second terminal 7 is fixedly connected to the limiting platform 6, and the second terminal 7 is electrically connected to the pin 10.
[0029] The upper coupling member 1 is provided with a plurality of contact end sleeves 3. The upper coupling member 1 and the contact end sleeves 3 are both fixedly connected to the terminal fixing seat 4. The upper coupling member 1 is sleeved on the outside of the contact end sleeves 3.
[0030] A spacer for accommodating the isolation and protective plate 9 is provided between several of the contact end sleeves 3.
[0031] The contact end sleeve 3 is provided with a socket 11, which is used to insert the pin 10.
[0032] The terminal block 4 is fixedly connected to the first terminal 5.
[0033] The working principle and beneficial effects of the above scheme are as follows:
[0034] This application provides an isolation and protection plate 9 around the pin 10, so that the isolation and protection plate 9 and the edge of the lower coupling member 2 form a small space to accommodate the pin 10, making it difficult for foreign objects to enter this space and damage the pin 10. Even if damage occurs in individual cases, it is highly likely to be limited to a group of damages, and it is not easy for large-scale damage to occur.
[0035] During use, the limiting platform 6 contacts the lower end of the upper coupling component 1 to prevent damage caused by excessive insertion.
[0036] Example 2
[0037] Please see Figure 4 , Figure 5 Based on Embodiment 1, a spring assembly 12 is provided in the socket 11. The spring assembly 12 is used to contact the pin 10 and is electrically connected to the first terminal 5.
[0038] The spring assembly 12 includes a fixing piece 13, an elastic piece 14, and a pressure piece 15. The fixing piece 13 and the pressure piece 15 are arranged in parallel. The fixing piece 13 is fixedly connected to the inner wall of the insertion hole 11. The fixing piece 13 and the pressure piece 15 are connected by the elastic piece 14. The elastic piece 14 is arc-shaped in its natural state.
[0039] A first connecting seat 16 is fixedly connected to the pressure plate 15, and a second connecting seat 17 is fixedly connected to the fixing plate 13. A connecting rod 18 is fixedly connected to the first connecting seat 16, and the connecting rod 18 is inserted and slidably inserted into the second connecting seat 17. A spring 19 is provided between the first connecting seat 16 and the second connecting seat 17, and the spring 19 is sleeved on the connecting rod 18.
[0040] The working principle and beneficial effects of the above scheme are as follows:
[0041] When the pin 10 is inserted into the socket 11, the pin 10 presses the elastic sheet 14, causing the elastic sheet 14 to deform. Under the action of the elastic sheet 14, the pressure sheet 15 moves relative to the fixed sheet 13, compressing the spring 19. The elastic force of the spring 19 acts on the elastic sheet 14 through the pressure sheet 15 and the first connecting seat 16, so that most of the elastic sheet 14 is in contact with the pin 10, increasing the contact area between the pin 10 and the elastic sheet 14, and ensuring good contact.
[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
