Description

Technical Field

[0001] This utility model relates to the field of connector fixing technology, specifically a self-locking mechanism for a vertical side-clamp connector. Background Technology

[0002] Traditional wire-to-board connectors are connection components that electrically connect wires to circuit boards. Their advantage is that they do not need to be soldered to the circuit board, allowing users to easily achieve electrical connection by plugging and unplugging.

[0003] To prevent the ribbon cable from coming loose after being inserted into the connector slot, most existing connectors use elastic clips to secure the cable. The ribbon cable has slots on both sides, and the elastic clips engage within these slots. For easy insertion and removal, the elastic clips have beveled edges on both sides to guide the cable insertion and removal. The slots containing the ribbon cable require a relatively precise fit with the beveled edges of the elastic clips; after repeated insertions and removals, jamming may occur.

[0004] Therefore, this utility model provides a vertical edge connector self-locking mechanism to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a self-locking mechanism for a vertical edge connector, which at least solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A self-locking mechanism for a vertical edge-lock connector includes a connector frame and a guide pin module. The guide pin module is inserted into the inside of the connector frame to form the connector body. Lock bodies are inserted into both sides of the connector frame, and lock heads are rotatably connected to the outer side of the lock bodies. The lower end of the connector frame has a placement slot for placing the guide pin module and a fixed bayonet. During the assembly of the connector, the guide pin module is inserted into the bottom end of the connector frame to form the basic internal structure of the connector.

[0007] As a further embodiment of this utility model, a housing is slidably fitted onto the outside of the connector frame, and grooves are provided on both sides of the inside of the housing. The housing fits onto the outside of the connector frame and plays the role of protecting the main body of the connector. At the same time, the grooves are concave rectangular grooves.

[0008] As a further embodiment of this utility model, the front and rear ends of the connector frame are fixedly connected with slide rails. The housing can slide on the slide rails of the connector frame through the slide grooves to realize the assembly and fixation of the housing and the connector frame. Locking grooves are opened at the upper ends of both sides of the connector frame, and the slide rails of the connector frame are L-shaped slide rails.

[0009] As a further embodiment of this utility model, a sealing plate is attached to the lower part of the connector frame, and round holes are opened on both sides of the surface of the sealing plate, and multiple pinholes are opened on the surface of the sealing plate.

[0010] As a further embodiment of this utility model, the lock head has a locking block fixedly connected to both the front and rear ends at the middle position, and a rotating shaft fixedly connected to both the front and rear ends at the lower end position. A raised anti-collision part is provided on one side of the lock head. The locking block is a triangular prism with a slope that extends outward, and the surface of the locking block is provided with anti-slip texture to increase the friction of the locking block.

[0011] As a further embodiment of this utility model, a slot is provided on the outer side of the lock body, and a rotating slot is provided at the front and rear ends of the inner side of the lock body. A connecting line is fixedly connected to one side of the connector frame, and the rotating shaft is composed of two semicircles with a gap in the middle.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. When this utility model is used, through the lock body and lock tongue structure, the connector frame presses down on the lower end of the lock head, so that the lock head rotates in the lock body through the rotating shaft. When the lock head rotates to the vertical state, the lock tongue at the upper end of the lock head is close to the inside of the lock groove, realizing the self-locking function of the connector and increasing the strength of the connector connection.

[0013] 2. When this utility model is used, by setting the sliding groove and other structures of the housing, the housing can slide on the slide rail of the connector frame through the sliding groove, so as to realize the assembly and fixation of the housing and the connector frame, which facilitates the assembly of the connector and facilitates the disassembly of the connecting wire for maintenance.

[0020] To address the problem of this situation, this utility model provides a vertical edge-locking connector self-locking mechanism.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 This utility model provides a self-locking mechanism for a vertical edge connector, including a connector frame 2 and a guide pin module 3. The guide pin module 3 is inserted into the inside of the connector frame 2 to form the connector body. Lock bodies 4 are inserted into both sides of the connector frame 2, and lock heads 5 are rotatably connected to the outer side of the lock bodies 4.

[0023] The lower end of the connector frame 2 is provided with a placement slot for the guide pin module 3 and a fixed bayonet. During the assembly of the connector, the guide pin module 3 is inserted into the bottom of the connector frame 2 to form the basic internal structure of the connector. The two sides of the connector frame 2 are provided with cavities to accommodate the lock body 4. The lock body 4 can be slidably inserted into the cavity to be fixed to the two sides of the connector frame 2. The lower end of the lock head 5 is rotatably connected to the inside of the lock body 4. The upper end of the lock head 5 is a forward-extending rectangular lock tongue structure, and the front end can extend to the inside of the two sides of the connector frame 2.

[0024] Please see Figure 2 In some embodiments, the connector frame 2 is slidably sleeved with a housing 1, and the housing 1 has sliding grooves 101 on both sides inside. The connector frame 2 is fixedly connected to slide rails 21 at both the front and rear ends. The housing 1 can slide on the slide rails 21 of the connector frame 2 through the sliding grooves 101 to realize the assembly and fixation of the housing 1 and the connector frame 2. Locking grooves 22 are provided at the upper ends of both sides of the connector frame 2.

[0025] The housing 1 is sleeved on the outside of the connector frame 2 to protect the main body of the connector. Meanwhile, the slide groove 101 is a concave rectangular groove, and the slide rail 21 of the connector frame 2 is an L-shaped slide rail. When the sliding cover of the housing 1 is attached to the outer end of the connector frame 2, the horizontal plate at the lower end of the L-shape can limit the housing 1 to prevent the housing 1 from being lifted directly in the vertical direction and causing the housing 1 to fall off. The rectangular locking tongue structure at the upper end of the locking head 5 can extend into the locking groove 22 inside the connector frame 2 to lock the connector frame 2.

[0026] Please see Figure 3 In some embodiments, a sealing plate 6 is attached to the lower part of the connector frame 2, and round holes are opened on both sides of the surface of the sealing plate.

[0027] Multiple pinholes are provided on the surface of the sealing plate 6, allowing the guide pins of the guide pin module 3 installed in the connector housing 2 to extend to the outside, enabling the connector to transmit data normally with the connected device. When the housing 1 is attached to the upper end of the connector housing 2, the sealing plate 6 and the housing 1 can be connected together by setting threaded nails or expansion screws at the round holes on both sides of the sealing plate 6 to realize the assembly of the connector.

[0028] Please see Figure 4 In some embodiments, the lock head 5 has a locking block 51 fixedly connected to both the front and rear ends of the middle position, a rotating shaft 52 fixedly connected to both the front and rear ends of the lower position, and a protruding anti-collision part 53 provided on one side of the lock head 5.

[0029] The locking block 51 is a sloping triangular prism with the slope extending outwards. The surface of the locking block 51 is provided with anti-slip texture to increase the friction of the locking block 51. The locking head 5 is rotatably connected to the inside of the lock body 4 through the rotating shaft 52. The anti-collision part 53 is made of soft plastic material. When the locking head 5 locks the connector frame 2, it prevents the locking force from being too great and causing damage to the connector frame 2, thus playing a role in protecting the connector frame 2.

[0030] In some embodiments, a slot 42 is provided on the outer side of the lock body 4, and a rotating slot 41 is provided at the front and rear ends of the inner side of the lock body 4. A connecting wire 7 is fixedly connected to one side of the connector frame 2.

[0031] The rotating shaft 52 consists of two semicircles with a gap in the middle. When the lock head 5 is rotatably connected to the inside of the lock body 4 through the rotating shaft 52, the semicircles of the rotating shaft 52 are engaged in the rotating groove 41 to realize the rotation of the lock head 5 and its engagement in the inside of the lock body 4. At the same time, the overall structure of the lock head 5 can rotate freely in the slot position of the lock body 4. The width of the slot 42 is slightly larger than the width of the middle position of the lock head 5, but the total width of the locking block 51 set in the middle position of the lock head 5 and the middle position of the lock head 5 is greater than the width of the slot 42. Therefore, when the lock head 5 is engaged in the inside of the lock groove 22, the locking blocks 51 at the front and rear ends of the lock head 5, through the relationship of the width being greater than the slot 42 and friction, fix the lock head 5 in the position of the slot 42, so that the lock head 5 always remains locked in the state of the connector frame 2 during the use of the connector.

[0032] When this utility model is used, when the connector is pressed onto the connecting device, due to the influence of the pressure reaction force, the lower end of the connector frame 2 presses down on the lock head 5, causing the lock head 5 to rotate inside the lock body 4 via the rotating shaft 52. When the lock head 5 rotates to a vertical state, the locking tongue at the upper end of the lock head approaches the inside of the lock groove 22, realizing the self-locking function of the connector and increasing the strength of the connector connection.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
