Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to a pin-type connector socket. Background Art

[0002] In the prior art, the connector socket generally includes a shell, and terminals responsible for current transmission and signal transmission are arranged in this shell. The conventional operation of this type of connector is to fix it directly on the circuit board and use flexible wires to achieve electrical connection with the circuit board. However, flexible wires can solve multi-directional electrical connections, but the stress and wear introduced by long-term deflection in the narrow space inside the equipment directly affect the service life of the product, and due to the wiring problem of the wiring socket, there is a risk of misassembly during assembly. In addition, in some specific application scenarios, the installation position of the connector is not the circuit board, but is transferred to a mounting panel. This change makes it difficult to accurately control the relative position between the connector and the circuit board due to the lack of a direct positioning mechanism, which in turn affects the stability of the electrical contact between the terminal and the circuit board, and may cause connection failure in extreme cases. Summary of the invention

[0003] In order to overcome the defects of the prior art and address the problems of unreliable and inconvenient connection of flexible wires, the utility model provides a pin-type connector socket.

[0004] The technical solution of the utility model: a pin-type connector socket, including a shell and a circuit board, the shell is equipped with a guide pin and a signal pin, the guide pin and the signal pin are both made of rigid metal material, the guide pin and the signal pin both include an insert segment and a fixed segment, the insert segment and the fixed segment are both in sheet shape, the insert segment is fixedly inserted in the shell, the insert segment and the fixed segment form an angle by bending, the end of each fixed segment extends integrally to form at least one needle body, the needle body penetrates upward from the bottom surface of the circuit board and is welded to a preset position of the circuit board.

[0005] By adopting the above technical solution, the guide pins and signal pins made of rigid metal materials can enhance the mechanical strength of the connection and the stability of the electrical contact compared to flexible wires. Even in a complex environment where the installation panel and the circuit board are not directly connected, the high reliability of the connection can be ensured, avoiding the problem of connection failure caused by position deviation; the bending design of the inserted segment and the fixed segment can flexibly adapt to its installation environment and optimize the electrical path; the design of the pin body directly passing through the bottom surface of the circuit board and welded at a preset position simplifies the assembly steps and reduces human errors during the assembly process; the rigid metal material and fixed plug-in method reduce the wire stress and wear caused by frequent bending in a small space, thereby significantly improving the durability and service life of the product and reducing maintenance costs.

[0006] In a possible design, a bending segment is integrally connected between the insert segment and the fixed segment, and the bending segment includes at least two obtuse corners.

[0007] With the above design, the design of multiple obtuse corners can disperse the stress of the bent segments, reduce thermal stress concentration, and improve structural strength. In addition, there is a makeshift space on the outside of the corner, which can more efficiently arrange the pins in a limited installation space, ensuring the effective length of the pins to achieve good electrical contact without excessively occupying space. It can also better adapt to the installation requirements of circuit boards at different angles.

[0008] In a possible design, a fixing frame is fixedly mounted on the bottom of the circuit board, and a plurality of fixing holes are formed on the fixing frame. The fixing segments are inserted into the fixing holes and the needles pass through the fixing holes.

[0009] With the above design, the fixing frame provides a solid mechanical support for the fixing segment of the pin, avoiding displacement caused by vibration or external force, thereby improving the stability and reliability of the entire connector socket; the fixing frame also ensures the precise positioning of each pin, and the worker only needs to align the fixing segment of the pin with the fixing hole and insert it, so that each pin body can accurately correspond to the predetermined welding position on the circuit board, improving the accuracy and consistency of the connection and reducing the difficulty of assembly.

[0010] In a possible design, the insert segment and the fixed segment are respectively provided with a plurality of limiting barbs in an integral manner in the width direction and are embedded and fixed with the corresponding housing and the fixing frame through the limiting barbs.

[0011] The above design prevents the corresponding pins from shifting due to vibration or external force during use, thereby improving the stability of the connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1-4 The pin connector socket shown includes a housing 1 and a circuit board 2. The housing 1 is equipped with a current guide pin 3 and a signal pin 4, which are used as terminals for current transmission and signal transmission respectively. The current guide pin 3 and the signal pin 4 are made of rigid metal materials, and can be made of copper, aluminum and other materials. The current guide pin 3 and the signal pin 4 are in a shape similar to the letter "L". Both include an insert segment 31 and a fixed segment 32. The insert segment 31 and the fixed segment 32 are in the shape of a sheet. The insert segment 31 is fixedly inserted into the housing 1. The insert segment 31 and the fixed segment 32 are bent to form an angle. The angle can be adjusted according to the installation environment, and the angle is mostly a right angle. The end of each fixed segment 32 extends integrally to form at least one needle body 33. The needle body 33 penetrates upward from the bottom surface of the circuit board 2 and is welded to a preset position of the circuit board 2. The number of pin bodies of the current guide pin 3 and the signal pin 4 can be adjusted according to specific application requirements. In the figure, the current guide pin 3 has three pin bodies 33 to meet the larger current carrying requirements, while the signal pin 4 has a single pin body 33 to ensure the pure transmission of the signal. The pin body 33 is actually stamped and formed by the fixed segment 32, and is connected to the fixed segment 32 as a whole, which reduces the additional parts assembly steps, simplifies the production process, and reduces the manufacturing cost. The integrated connection also helps to improve the overall strength and reliability of the product.

[0022] A bending segment 34 is integrally connected between the insert segment 31 and the fixed segment 32, and the bending segment 34 includes at least two obtuse corners 341. For example, the design of a right angle between the insert segment 31 and the fixed segment 32 can be achieved through two obtuse corners 341, otherwise the stress is concentrated at the right angle position, and it is easy to break, etc., thereby improving the overall structural strength and durability of the connector and ensuring stability under long-term use. The space left at the outer position of each corner 341 not only realizes the efficient layout of the pins in a compact installation environment, but also ensures sufficient pin length to maintain electrical contact performance, while avoiding unnecessary space occupation, so that the connector can more flexibly adapt to various installation angles and space constraints, and broaden the scope of use.

[0023] A fixing frame 5 is fixedly installed at the bottom of the circuit board 2. A plurality of fixing holes 51 are opened on the fixing frame 5. Each fixing segment 32 is inserted into the corresponding fixing hole 51, and the needle body 33 passes through the corresponding fixing hole 51. The fixing segments 32 of each pin are integrated and limitedly installed in the same fixing frame 5, which effectively resists the displacement caused by external vibration and ensures the installation stability of each pin. At the same time, the pin fixing segments 32 form a plug-and-play positioning, which simplifies the assembly process. The shape of the fixing hole 51 can be a large hole adapted to the fixing segment 32 dispersed into a plurality of small holes adapted to the needle body 33, which ensures the accurate positioning of the needle body 33 in the fixing frame 5 and avoids misalignment during installation. At the same time, the layout of the plurality of small holes around the large hole and the position between the adjacent small holes can support the needle body 33 and enhance the structural strength of the needle body 33.

[0024] The inserted segment 31 and the fixed segment 32 are respectively provided with a plurality of limiting barbs 35 in the width direction and are embedded and fixed with the corresponding shell 1 and the fixing frame 5 through the limiting barbs 35. These limiting barbs form a stable embedding fit with the shell 1 and the fixing frame 5, reducing the problems of poor contact or loose connection that may be encountered during long-term use.
