Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an electrical connector. Background Technology

[0002] Electrical connector assemblies, also known as circuit connectors, are conductor devices used to bridge two conductors in a circuit, allowing current or signals to flow from one conductor to the other. They are widely used in various electrical circuits to connect or disconnect current or signals.

[0003] A connector consists of a plug assembly and a socket. The socket typically contains multiple rows of terminals (at least two rows). In production, the terminals are usually arranged in several rows, and then the rear ends of the multiple rows of terminals are bent and soldered directly onto a circuit board, also arranged in the same array. This requires a lot of space at the back of the socket for soldering the terminals, meaning it occupies a lot of space and requires a longer circuit board to accommodate the multiple rows of terminals. If there are many rows of terminals (more than three rows), the required length of the circuit board is also large, which is not conducive to reducing the overall size of the connector and makes it difficult to install it on the corresponding products.

[0004] Therefore, it is necessary to propose an electrical connector to reduce the space occupied by the plug terminals soldered on the circuit board, while increasing the fixing force of the plug terminals, and ultimately reducing the overall size of the connector to facilitate subsequent installation. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes an electrical connector that reduces the space occupied by the plug terminals soldered onto the circuit board, while simultaneously increasing the fixing force of the plug terminals, ultimately reducing the overall size of the connector and facilitating subsequent installation.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes an electrical connector, including a plug assembly and a socket. The plug assembly and the socket are detachably connected and electrically connected. The socket includes a first ribbon cable assembly, a second ribbon cable assembly, and a fixing base. The fixing base is fixedly connected to a PCB board. One end of the first ribbon cable assembly and one end of the second ribbon cable assembly both pass through the fixing base and are fixedly connected to and flush with the fixing base. The other ends of the first ribbon cable assembly and the other ends of the second ribbon cable assembly are both bent and staggered and fixedly connected to the PCB board and electrically connected to the PCB board. The fixing base has a ribbon cable fixing part. One end of the first ribbon cable assembly and one end of the second ribbon cable assembly both pass through the ribbon cable fixing part and are fixedly connected to the ribbon cable fixing part. The ribbon cable fixing part includes a support plate, a first ribbon cable fixing frame, and a second ribbon cable fixing frame. The first ribbon cable fixing frame and the second ribbon cable fixing frame are both fixedly connected to one side of the support plate. The first ribbon cable assembly passes through the first ribbon cable fixing frame and is fixedly connected to the first ribbon cable fixing frame. The second ribbon cable assembly passes through the second ribbon cable fixing frame and is fixedly connected to the second ribbon cable fixing frame.

[0008] Furthermore, the first ribbon cable assembly includes a plurality of first connecting posts arranged in sequence, and the second ribbon cable assembly includes a plurality of second connecting posts arranged in sequence. One end of each of the plurality of first connecting posts and one end of each of the plurality of second connecting posts penetrates the fixing base and is fixedly connected to the fixing base and arranged flush with it. The other end of each of the plurality of first connecting posts is bent and fixedly connected to the PCB board in a staggered manner and is electrically connected to the PCB board. The plurality of first connecting posts are staggered from the plurality of second connecting posts.

[0009] Furthermore, the length of the first connecting post is a, and the length of the second connecting post is b, where a is less than b.

[0010] Furthermore, the PCB board is provided with a plurality of first insertion holes and a plurality of second insertion holes. The plurality of first insertion holes are arranged sequentially, and the plurality of second insertion holes are arranged sequentially and staggered on one side of the plurality of first insertion holes. One end of the plurality of first connecting posts corresponds to one of the plurality of first insertion holes, and one end of the first connecting post is inserted into the first insertion hole. One end of the plurality of second connecting posts corresponds to one of the plurality of second insertion holes, and one end of the second connecting post is inserted into the second insertion hole.

[0011] Furthermore, the second cable holder is located above the first cable holder.

[0012] Furthermore, mounting bosses are provided on both sides of the mounting base, and the mounting bosses are fixedly connected to the PCB board.

[0013] Furthermore, the mounting boss is provided with a first fixing hole, and the PCB board is provided with a second fixing hole, with the first fixing hole and the second fixing hole aligned.

[0014] Furthermore, the fixing base is provided with a plug slot and two limiting plates. One end of the first ribbon cable assembly and one end of the second ribbon cable assembly both extend into the plug slot. The two limiting plates are fixedly connected to the groove wall of the plug slot and are symmetrically arranged. The plug assembly is inserted into the plug slot and electrically connected to the first ribbon cable assembly and the second ribbon cable assembly. One side of the plug assembly is provided with two limiting grooves, and the two limiting grooves correspond one-to-one with the two limiting plates. The limiting plates are received in the limiting grooves.

[0015] The beneficial effects of this utility model are:

[0016] This invention uses a cable fixing part on a fixing base to fix one end of the first cable assembly and one end of the second cable assembly. A support plate enhances the stability of the first and second cable fixing brackets. These brackets respectively fix the first and second cable assemblies, thereby improving their stability. This ensures that one end of each cable assembly extends into the fixing base and is flush with it, thus maintaining the original insertion method and facilitating plug insertion. The other ends of the first and second ribbon cable assemblies are bent and staggered and fixed to the PCB board. Because the connection positions are staggered, the area occupied behind the fixing base is reduced, thereby reducing the length of the PCB board and reducing the external space occupied by the connector. In summary, this electrical connector can effectively reduce the space occupied by the plug terminals on the circuit board, thereby reducing the size of the connector, without hindering the normal insertion of the plug assembly, while improving the fixing force of the plug terminals, ultimately reducing the overall size of the connector and facilitating subsequent installation.

Detailed Implementation

[0024] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0025] Please refer to Figures 1-4 This utility model proposes an electrical connector, including a plug assembly 1 and a socket 2. The plug assembly 1 and the socket 2 are detachably connected and electrically connected. The socket 2 includes a first ribbon cable assembly 22, a second ribbon cable assembly 23, and a fixing seat 24. The fixing seat 24 is an integral structure and is fixedly connected to a PCB board 21. One end of the first ribbon cable assembly 22 and one end of the second ribbon cable assembly 23 pass through the fixing seat 24 and are fixedly connected to the fixing seat 24 and flush with it. The other end of the first ribbon cable assembly 22 and the other end of the second ribbon cable assembly 23 are bent and staggered and fixedly connected to the PCB board 21 and are electrically connected to the PCB board 21.

[0026] In this embodiment, during the assembly of the first ribbon cable assembly 22 and the second ribbon cable assembly 23, a fixing seat 24 is used to fix one end of the first ribbon cable assembly 22 and one end of the second ribbon cable assembly 23, so that one end of the first ribbon cable assembly 22 and one end of the second ribbon cable assembly 23 extend into the fixing seat 24 and are flush. This does not change the original insertion method and facilitates the insertion of the plug assembly 1. The other ends of the first ribbon cable assembly 22 and the second ribbon cable assembly 23 are bent and staggered and fixedly connected to the PCB board 21. Since the connection positions of the other ends of the first ribbon cable assembly 22 and the second ribbon cable assembly 23 with the PCB board 21 are staggered, a part of the second ribbon cable assembly 23 can still be placed in the space inside the first ribbon cable assembly 22. This reduces the area occupied behind the fixing seat 24, thereby reducing the length of the PCB board 21 and reducing the external space occupied by the plug socket 2.

[0027] In summary, this electrical connector can effectively reduce the space occupied by the soldered terminals on the circuit board, thereby reducing the size of the socket, without hindering the normal insertion of the plug assembly, ultimately reducing the overall size of the connector and facilitating subsequent installation.

[0028] In this embodiment, the first ribbon cable assembly 22 includes a plurality of first connecting posts 221 arranged sequentially, and the second ribbon cable assembly 23 includes a plurality of second connecting posts 231 arranged sequentially. One end of each of the plurality of first connecting posts 221 and one end of each of the plurality of second connecting posts 231 penetrates through the fixing base 24 and is fixedly connected to the fixing base 24 and arranged flush with it. The other ends of the plurality of first connecting posts 221 are bent and staggered and fixedly connected to the PCB board 21 and are all electrically connected to the PCB board 21. The plurality of first connecting posts 221 and the plurality of second connecting posts 231 are staggered and distributed. The plurality of first connecting posts 221 and the plurality of second connecting posts 231 are soldered to the PCB board 21. When the first connecting post 221 is located on one side of the second connecting post 231, and the first connecting post 221 is staggered on one side between the second connecting post 231, which effectively reduces the external space occupied by the first ribbon cable assembly 22 and the second ribbon cable assembly 23 when connected to the PCB board 21; one end of the first connecting post 221 is provided with a first connecting rod 2211, and one end of the second connecting post 231 is provided with a second connecting rod 2311. The first connecting rod 2211 and the second connecting rod 2311 are aligned vertically. The first connecting rod 2211 and the second connecting rod 2311 are both located in the fixing seat 24. The first connecting rod 2211 and the second connecting rod 2311 are both used to form an electrical connection with the plug assembly 1.

[0029] In this embodiment, the length of the first connecting post 221 is a, and the length of the second connecting post 231 is b, where a is less than b. This ensures that when the first connecting post 221 and the second connecting post 231 are bent at 90 degrees, the second connecting post 231 can be located outside the first connecting post 221.

[0030] In this embodiment, the PCB board 21 is provided with a plurality of first insertion holes 211 and a plurality of second insertion holes 212. The plurality of first insertion holes 211 are arranged sequentially, and the plurality of second insertion holes 212 are arranged sequentially and staggered on one side of the plurality of first insertion holes 211. One end of a plurality of first connecting posts 221 corresponds to one of the plurality of first insertion holes 211 and is inserted into the first insertion hole 211. One end of a plurality of second connecting posts 231 corresponds to one of the plurality of second insertion holes 211. 212 correspond one-to-one, with one end of the second connecting post 231 inserted into the second insertion hole 212; both the first insertion hole 211 and the second insertion hole 212 are electrically connected to the PCB board. When multiple first connecting posts 221 are inserted into the PCB board 21, they are inserted into multiple first insertion holes 211 respectively and then fixed by soldering. When multiple second connecting posts 231 are inserted into the PCB board 21, they are inserted into multiple second insertion holes 212 respectively and then fixed by soldering.

[0031] In this embodiment, the mounting base 24 is provided with a ribbon cable fixing part 241, which is set perpendicular to the PCB board 21. One end of the first ribbon cable assembly 22 and one end of the second ribbon cable assembly 23 pass through the ribbon cable fixing part 241 and are fixedly connected to the ribbon cable fixing part 241. The ribbon cable fixing part 241 is used to fix the first ribbon cable assembly 22 and the second ribbon cable assembly 23. When assembling the first ribbon cable assembly 22 and the second ribbon cable assembly 23, one end of the first ribbon cable assembly 22 and one end of the second ribbon cable assembly 23 can be directly inserted into the ribbon cable fixing part 241.

[0032] In this embodiment, the ribbon cable fixing part 241 includes a support plate 2411, a first ribbon cable fixing bracket 2412, and a second ribbon cable fixing bracket 2413. The support plate 2411 is perpendicular to the PCB board 21. The first ribbon cable fixing bracket 2412 and the second ribbon cable fixing bracket 2413 are both fixedly connected to one side of the support plate 2411. The first ribbon cable assembly 22 passes through the first ribbon cable fixing bracket 2412 and is fixedly connected to the first ribbon cable fixing bracket 2412. The second ribbon cable assembly 23 passes through the second ribbon cable fixing bracket 2413 and is fixedly connected to the second ribbon cable fixing bracket 2413. When assembling the first ribbon cable assembly 22 and the second ribbon cable assembly 23, the first ribbon cable assembly 22 is aligned with the first ribbon cable fixing bracket 2412 and inserted and passed through, and the second ribbon cable assembly 23 is aligned with the second ribbon cable fixing bracket 2413 and inserted and passed through.

[0033] In this embodiment, since the length of the second ribbon cable assembly 23 is greater than the length of the first ribbon cable assembly 22, it is necessary to set the second ribbon cable fixing bracket 2413 above the first ribbon cable fixing bracket 2412.

[0034] In this embodiment, mounting bosses 242 are provided on both sides of the mounting base 24. The mounting bosses 242 are fixedly connected to the PCB board 21 by rivets or screws. The mounting bosses 242 are provided with a first fixing hole 2421, and the PCB board 21 is provided with a second fixing hole 213. The first fixing hole 2421 and the second fixing hole 213 are aligned. When the mounting bosses 242 are installed on the PCB board 21, screws or rivets are sequentially locked into the first fixing hole 2421 and the second fixing hole 213 to fix the mounting bosses 242 on the PCB board 21.

[0035] In this embodiment, the fixing base 24 is provided with a plug slot 243 and two limiting plates 244. One end of the first ribbon cable assembly 22 and one end of the second ribbon cable assembly 23 extend into the plug slot 243. The two limiting plates 244 are fixedly connected to the groove wall of the plug slot 243 and are symmetrically arranged. The plug assembly 1 is inserted into the plug slot 243 and is electrically connected to the first ribbon cable assembly 22 and the second ribbon cable assembly 23. Two limiting grooves 11 are provided on one side of the plug assembly 1, and the two limiting grooves 11 correspond one-to-one with the two limiting plates 244. The limiting plate 244 is housed in the limiting groove 11. When the plug assembly 1 is plugged into the socket 2, the plug assembly 1 is aligned with the socket 243 and then inserted into the socket 243. After the plug assembly 1 is fully inserted, the plug assembly 1 forms a contact electrical connection with the first ribbon cable assembly 22 and the second ribbon cable assembly 23. During the insertion process, the two limiting plates 244 respectively form a sliding engagement with the two limiting grooves 11 to limit the sliding trajectory of the plug assembly 1, thereby enabling the plug assembly 1 to be inserted smoothly.

[0036] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
