Description

Technical Field

[0001] This utility model relates to the field of high-speed connector technology, specifically a connector with a tightening mechanism. Background Technology

[0002] With the continuous improvement of high-speed connector signal rates, a new structure is needed to ensure signal stability and contact stability. This structure not only satisfies the reliability of terminal-PCB contact but also ensures that the connector is not displaced when offset loads are applied or the connector is roughly handled, thereby improving the connector's durability. Utility Model Content

[0003] The purpose of this invention is to provide a connector for a tightening mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A connector for a tightening mechanism includes a fixed cover and terminals. The fixed cover is an L-shaped stainless steel cover covering the rear end of the terminals. The fixed cover is characterized by having a right end cover and a left end cover installed on both sides of the fixed cover. The upper ends of the left end cover and the right end cover are connected to the two sides of the fixed cover by a snap-fit ​​structure. The lower ends of the left end cover and the right end cover are connected to a PCB board. The PCB board is fixedly connected to the left end cover and the right end cover on the upper left and right sides of the board by two fixing screws passing through the board body from the lower end of the PCB board.

[0006] As a further embodiment of this utility model, the left and right end caps are provided with observation holes on their sides, so that when the screw fixes the terminal to the PCB board, the tail end of the screw can be observed through the observation holes.

[0007] As a further improvement of this utility model, the lower ends of the left and right end covers are provided with floating grooves, which are formed by... Figure 4 It can be seen that a gap of 0.19 mm is reserved between the width of the floating groove and the connection of the terminal.

[0008] As a further embodiment of this utility model, both the left and right end caps are provided with buckles at their upper ends, one end of the fixed cap has a comb-tooth structure, and a horizontally placed limiting plate is provided in front of the buckles. The limiting plate and the end cap are integrally formed.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. When this utility model is used, the left end cover and the right end cover have observation holes on their sides. When the screw fixes the terminal to the PCB board, the tail end of the screw can be observed through the observation holes. When the tail end of the screw does not protrude from the observation holes, it can be determined that the screw is not locked in place. This serves to observe whether the screw is locked in place and ensure the stability of the terminal.

[0011] 2. In use, the lower ends of the left and right end covers are provided with floating grooves, which allow for the movement of the material. Figure 4 It can be seen that a gap of 0.19 mm is reserved between the width of the floating groove and the connection of the terminal. This gap ensures that the floating end cap does not break the terminal cover during transportation. Attached Figure Description

[0017] 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.

[0018] In this invention, the term "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described as "exemplary" in this invention is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to implement and use this invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of this invention with unnecessary detail. Therefore, this invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed herein.

[0019] Example

[0020] Please see Figures 1-4 In this embodiment of the utility model, a connector with a tightening mechanism includes a fixed cover 1 and a terminal 5. The fixed cover 1 is an L-shaped stainless steel cover covering the rear end of the terminal 5. The fixed cover 1 is characterized by having a right end cover 2 and a left end cover 3 installed on both sides of the fixed cover 1. The upper ends of the left end cover 3 and the right end cover 2 are connected to the two sides of the fixed cover 1 through a snap-fit ​​structure. The specifications of the right end cover 2 are the same as those of the left end cover 3. The lower ends of the left end cover 3 and the right end cover 2 are connected to a PCB board 4. The PCB board 4 is fixedly connected to the left end cover 3 and the right end cover 2 on the upper left and right sides of the board body by two fixing screws passing through the lower end of the PCB board body. The screws tighten the crimped connector onto the PCB board 4, so that the terminal head is in complete contact with the PCB board 4, ensuring stable signal contact.

[0021] The left end cover 3 and the right end cover 2 have observation holes 21 on their sides. When the screw fixes the terminal to the PCB board 4, the tail end of the screw can be observed through the observation hole 21. When the tail end of the screw does not protrude from the observation hole, it can be determined that the screw is not locked in place. This serves to observe whether the screw is locked in place and ensure the stability of the terminal.

[0022] The lower ends of the left end cap 3 and the right end cap 2 are provided with floating grooves 22, which are formed by... Figure 4 It can be seen that a gap of 0.19 mm is reserved between the width of the floating groove 22 and the connection of the terminal 5. This gap ensures that the floating end cap does not break the terminal cover during transportation.

[0023] Both the left end cover 3 and the right end cover 2 are provided with buckles 23 at their upper ends. One end of the fixed cover 1 has a comb tooth structure. The buckles 23 can slide into the gaps of the comb teeth of the fixed cover 1 to realize the assembly of the fixed cover 1, the left end cover 3 and the right end cover 2. A horizontal limiting plate 24 is also provided in front of the buckles 23. The limiting plate 24 is integrally formed with the end cover and can prevent the fixed cover 1 from tilting up.

[0024] 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.
