Description

Technical Field

[0001] The present invention relates to the technical field of FPC connectors, and in particular to a connector with stable component connection. Background Art

[0002] FPC connector is an electronic component used to connect flexible printed circuit boards (FPCs). It is mainly used to realize signal and power transmission between FPC and other circuit boards or electronic devices. FPC connectors usually consist of two parts: a socket and a plug. The stability of the connection is ensured by a precise contact structure. Its small size and adaptability to bending make it widely used in various electronic devices. In order to ensure the connection stability of the socket and the plug, it is usually necessary to set a locking component on the socket or the plug. This locking component is usually a screw.

[0003] A Chinese invention patent with announcement number CN102709736A discloses an FPC connector for connecting an FPC with a circuit board, comprising: an insulating body, a plurality of conductive terminals mounted on the insulating body, and a pressure plate device fixed on the insulating body. The insulating body is provided with a docking space. The conductive terminal has a contact arm, a pressure arm, and a connecting portion connected to the circuit board. Both the contact arm and the pressure arm extend into the docking space. The pressure plate device comprises a pressure plate. A plurality of grooves and a convex shaft located in the grooves are provided at one end edge of the pressure plate. The pressure arm passes through the grooves and presses against the top of the convex shaft. A pressure block is formed on the bottom side of the pressure plate. The pressure plate device also comprises a stopper portion that cooperates with the free end of the pressure arm to limit the displacement of the end of the pressure arm along the height direction of the FPC connector. The overall structure of the connector of the present invention is simple and can provide a greater holding force for the FPC.

[0004] The above-mentioned patent does not use screws, but is realized by a pressure plate structure fixed on the insulating body. Although the connection stability of the FPC connector is improved to a certain extent, the structure is complex, the production cost is high, and the installation is not convenient enough. In view of this, the present application is filed. Summary of the invention

[0005] To this end, the present invention provides a connector with stable component connection to solve the above-mentioned problem.

[0006] The present invention provides the following technical solution: a connector with stable component connection, comprising a shell, a detachable clamping piece placed in the shell, and a connecting terminal installed in the shell by the detachable clamping piece, wherein the shell is provided with a contact terminal for contacting and connecting with the connecting terminal, the detachable clamping piece is composed of a main body and a connecting piece arranged on one side of the main body, and a through-fixing groove for the connecting terminal to be inserted is provided in the connecting piece. In the present invention, the connecting terminal is locked and fixed by the detachable clamping piece, and when the connecting terminal is not inserted, only the upper connecting guide rod of the detachable clamping piece is placed in the limiting groove of the shell, and the detachable clamping piece can be easily taken out by lifting it upwards, and when the connecting terminal is connected, the detachable clamping piece and the shell need to be inserted simultaneously. Inside the body, the lateral movement of the detachable clip is blocked by the limit groove, and it can only perform a short-distance rotational movement around the connecting guide rod. After the connecting terminal is inserted, the detachable clip is pressed downward again, so that the detachable clip and the connecting terminal form a mutually restrained structure, thereby realizing the locking and fixation of the connecting terminal. When disassembly is required, it is only necessary to lift one end of the detachable clip upward to make the detachable clip break away from the restricting effect on the connecting terminal, and then the connecting terminal can be removed. Compared with the existing connector structure, the present invention has a simple structure while still maintaining a better locking and fixing effect. Due to the relatively simple structure, the preparation and production process is also relatively simple, the production cost is low, and the operation is also relatively simple and quick, without the need for cumbersome operations, and has a high application value.

[0007] As a preferred solution of the present invention, insulating sheets are provided on both sides of the shell, and an external bracket is provided on the outer side of the insulating sheet for welding to a specified position of the circuit board. In order to meet the basic usage requirements of the present invention, the setting of the insulating sheet improves the insulation effect between the connector and the external structure to avoid being easily affected by other structures.

[0008] As a preferred solution of the present invention, limiting plates are provided on both sides of the main board body to limit the main board body from entering too deep into the shell, so that the detachable clip is not a simple sheet structure, avoiding the main board body from directly entering the shell during use. The limiting plates can be located outside the shell to form a fitting structure.

[0009] As a preferred solution of the present invention, connecting guide rods are symmetrically arranged on both sides of the connecting plate, and a limiting groove for inserting the connecting guide rods is opened in the shell. With the cooperation of the connecting guide rods and the limiting plates, the detachable clip can maintain a relatively stable state after being installed on the shell, and the overall structure is a state that can rotate within a certain range but will not be too loose.

[0010] As a preferred solution of the present invention, a longitudinally penetrating heat conduction groove is provided at the bottom of the shell, and the heat conduction groove is located below the connecting terminal to provide a certain heat dissipation effect for the connecting terminal to avoid serious heating at the terminal that affects use.

[0011] As a preferred solution of the present invention, a rear slot is opened on the bottom side of the inner wall of the shell, and the bottom of the connecting terminal is clamped in the rear slot. The setting of the rear slot provides an installation space for the rear half of the connecting terminal, which improves stability and increases the fitting area, which helps heat dissipation.

[0012] As a preferred solution of the present invention, the connecting terminal includes a main terminal, an upper connecting end arranged above the front end of the main terminal, a lower connecting end arranged below the front end of the main terminal, and a rear connecting end arranged below the rear side of the main terminal.

[0013] As a preferred solution of the present invention, the upper connecting end is inserted into the fixing groove of the detachable clamping member and then enters the housing to connect with the contact terminal. The shape of the upper connecting end is specifically a horizontally placed L-shape. Figure 2 As shown, through this structural design, the upper connecting end can be effectively combined with the connecting piece after being inserted into the fixing groove, so that after the connecting piece is pressed down, the upper connecting end can be effectively clamped in the shell, and the locking effect is better. The rear connecting end is inserted into the rear slot, which improves stability and increases the fitting area, which helps heat dissipation.

[0014] As a preferred solution of the present invention, the method for preparing the connecting terminal is: S1. Material pre-processing: select metal materials with good conductivity and corrosion resistance as raw materials, which can maintain stable performance under various stress conditions. Specifically, it can be any one of copper, aluminum and copper-aluminum alloy. Wash the raw materials with water and dry them, and then cut them into the required approximate size to obtain terminal blanks, so as to facilitate subsequent processing and molding. The specific shape will be processed in subsequent steps; S2, forming. This step requires that the cutting data be preset on the cutting machine according to the shape of the connection terminal, and then the subsequent processing can be carried out. The terminal blank is heated to make the material soft. The heating temperature and time are adaptively adjusted according to the type and thickness of the material to prevent overheating from causing the material performance to deteriorate. Then the terminal blank is placed on the cutting machine, and the excess part of the terminal blank is cut off by the cutting machine to form a sheet terminal. This step has formed the basic shape of the terminal; S3, finishing, grinding the surface of the sheet terminal, so that the burrs and protrusions generated during the cutting process of the sheet terminal can be removed, to prevent the burrs and protrusions from affecting the subsequent electroplating effect; S4, post-processing, cleaning and degreasing the terminals to remove oil and oxides on the terminal surface to provide a good environment for electroplating; S5, electroplating treatment, immerse the terminal in an electroplating solution containing tin ions, and deposit a layer of tin on the surface of the terminal through electrolysis. After the electroplating is completed, the terminal is cleaned and dried. Electroplating can effectively improve the conductivity, corrosion resistance and aesthetics of the terminal.

[0015] The beneficial effects of the present invention are as follows: In the present invention, the connecting terminal is locked and fixed by a detachable clamping piece. When the connecting terminal is not inserted, only the upper connecting guide rod of the detachable clamping piece is placed in the limiting groove of the shell. The detachable clamping piece can be easily taken out by lifting it upward. When the connecting terminal is connected, it is necessary to insert the detachable clamping piece and the inside of the shell at the same time. The lateral movement of the detachable clamping piece is blocked by the limiting groove and can only perform a short-distance rotational movement around the connecting guide rod. After the connecting terminal is inserted, the detachable clamping piece is pressed downward again, so that the detachable clamping piece and the connecting terminal form a mutually restrained structure, thereby realizing the locking and fixing of the connecting terminal. Compared with the connector in the prior art, the connector of the present invention has a simple structure and low cost, does not require the use of screws, is quick to operate, achieves an excellent locking and fixing effect at a relatively low cost, and has a great technical progress.
