Description

Technical Field

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

[0002] In recent years, with the rapid advancement of information technology and the multifunctional integration of electronic devices, the performance requirements for connectors are no longer limited to basic electrical connections, but have expanded to higher data transmission speeds, more stable signal quality, and stronger environmental adaptability. In traditional connector socket designs, flexible wires are often used as connecting wires for terminals. Although this solution provides flexibility and convenience in connection to a certain extent, especially in scenarios that need to adapt to complex or non-standard interfaces, it has exposed a series of limitations in long-term use.

[0003] The primary problem is the stability and integrity of signal transmission. Due to their physical properties, flexible wires are easily affected by external forces such as bending and stretching, which causes changes in the internal structure of the conductor and, in turn, changes in resistance, which is particularly unfavorable for high-current transmission applications. Secondly, the durability and long-term reliability of flexible wires are also problems to be solved, especially under harsh conditions such as frequent plugging and unplugging, high temperature, and vibration. The wires are prone to wear and breakage, shortening the service life of the connector. Summary of the invention

[0004] In order to overcome the defects of the prior art, the utility model provides a welding wire type connector socket in view of the problems that the flexible wire connection is unreliable and not durable.

[0005] The technical solution of the utility model includes: a shell and a circuit board, the shell is equipped with a guide pin and a signal terminal, the guide pin is made of a rigid metal material, and includes 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 extends upward from the bottom surface of the circuit board and is welded to a preset position of the circuit board; the signal terminal includes a terminal wire and a pin piece, the pin piece is made of a rigid metal material, the terminal wire extends from the shell and is connected to one end of the pin piece, and the other end of the pin piece extends upward from the bottom surface of the circuit board and is welded to the circuit board.

[0006] By adopting the above technical solution, the current guide pins and signal terminal pins made of rigid metal materials have higher mechanical strength and deformation resistance than traditional flexible wires or other softer materials. The fixed structure and pin body design formed by bending ensure that the stability of the connector is enhanced during long-term use and multiple plugging and unplugging, reducing failures caused by physical wear or stress accumulation, extending the service life, and effectively reducing the resistance and interference in the current guide transmission process, improving the current transmission efficiency, which is especially suitable for high current transmission application scenarios; and the bending design of the insert segment and the fixed segment can be flexibly adapted to The electrical path is optimized according to its installation environment; the design of the pin body and the pin part directly passing through the bottom surface of the circuit board and being welded at the preset position constitutes a welding wire connection method, which simplifies the production and assembly process, improves production efficiency, and optimizes the wiring space of the circuit board to meet the needs of circuit integration; the terminal wire can provide the necessary flexibility in the signal terminal. If the signal path needs to be changed or a terminal needs to be replaced, the terminal wire connection method is easier to operate, and the peripheral space of the terminal wire has been supported by the guide pin, which is not easily affected by external forces such as bending and stretching, and can ensure the reliability of signal transmission.

[0007] In one possible design, a fixing frame is fixedly installed at the bottom of the circuit board, and a plurality of limiting holes are provided on the fixing frame; the pin component includes a needle head, a limiting portion, and a tail clamping portion for clamping and fixing the terminal wire, the limiting portion has a wedge-shaped protrusion, and one side of the limiting hole has an elastic card block, and the wedge-shaped protrusion and the elastic card block are snap-fitted to fix the pin component.

[0008] With the above design, the fixing frame provides a solid mechanical support for the pin component, avoiding displacement caused by vibration or external force, thereby improving the stability and reliability of the entire connector socket; the wedge-shaped protrusion and the elastic card block form a tight snap fit, ensuring the precise positioning of the pin component on the circuit board, preventing the pin component from shifting during welding or use, and enhancing the stability of the overall structure.

[0009] In one possible design, the needle penetrates the circuit board, and the cross-section of the needle is "C"-shaped, which is surrounded by two parallel plates and one vertical connecting plate. The needle is integrally connected to the limiting part and is stamped from the same piece of metal sheet.

[0010] With the above design, the "C"-shaped cross-sectional shape can provide lateral support for the needle, enhance the needle's anti-bending ability and holding force, and the enclosure features in the structure help shield external electromagnetic interference and maintain signal purity. It is particularly suitable for high-frequency signal transmission, reducing signal attenuation and distortion, and improving the stability and integrity of signal transmission. In addition, integrated stamping molding helps reduce processing difficulty, simplify the production process, and reduce manufacturing costs.

[0013] 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.

[0014] 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 guide pins in a limited installation space, ensuring the effective length of the guide 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.

[0028] like Figure 1-6 The soldering wire connector socket shown in the figure includes a housing 1 and a circuit board 2. The housing 1 is equipped with a guide pin 3 and a signal terminal 4. The guide pin 3 is made of a rigid metal material and is in an "L" shape. It includes an insert segment 31 and a fixed segment 32. The insert segment 31 and the fixed segment 32 are both in the form of a sheet. The insert segment 31 is fixedly inserted in 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. 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 passes upward from the bottom surface of the circuit board 2 and is welded to a preset position of the circuit board 2. The signal terminal 4 includes a terminal wire 41 and a pin member 42. The pin member 42 is made of a rigid metal material. The terminal wire 41 extends from the housing 1 and is connected to one end of the pin member 42. The other end of the pin member 42 passes upward from the bottom surface of the circuit board 2 and is welded to the circuit board 2. The rigid metal material can be copper, aluminum and other materials, which can meet the rigidity continuity requirements while also providing a certain rigidity strength. The number of pin bodies 33 of the guide pin 3 can be adjusted according to the specific application requirements. In the figure, the guide pin 3 has two pin bodies 33 to meet the current carrying requirements of a certain requirement, while the signal terminal 4 is a single pin part 42 to ensure the pure transmission of the signal. The pin body 33 is actually formed by stamping 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. The use of terminal wires 41 and pin parts 42 in the signal terminal 4 allows flexible adjustment of the wiring path to adapt to the complex and changeable layout requirements on the circuit board 2, and can be directly welded and fixed to the circuit board 2 to achieve an integrated plug-in connection with the guide pin 3 to ensure the efficiency of the connection.

[0029] like Figure 4 , 6As shown, a fixing frame 5 is fixedly installed at the bottom of the circuit board 2, and a plurality of limiting holes 51 are formed on the fixing frame 5; the pin member 42 includes a needle head 421, a limiting portion 422, and a tail clamping portion 423 for clamping and fixing the terminal wire 41, the limiting portion 422 has a wedge-shaped protrusion 4221, and a side of the limiting hole 51 has an elastic block 52, and the wedge-shaped protrusion 4221 and the elastic block 52 are snap-fitted to fix the pin member 42. When the pin member 42 is inserted, the wedge-shaped protrusion 4221 gradually penetrates into the limiting hole 51, and the wedge-shaped protrusion 4221 and the elastic block 52 form a tight snap-fit. The elasticity of the elastic block 52 can be reversed to release the snap-fit ​​and easily disassemble the pin member 42, so as to adapt to the configuration of pin members 42 of different specifications or quantities, thereby enhancing the adaptability of the product. In addition, the elastic block 52 can also provide a certain buffering effect when the needle head 421 is plugged in, so as to prevent the signal terminal 4 from being damaged during the plugging process.

[0030] like Figure 6 As shown, the needle 421 penetrates the circuit board 2, and the cross section of the needle 421 is "C" shaped, which is respectively surrounded by two parallel pieces 4211 and one vertical connecting piece 4212. The "C" shaped cross section shape can provide lateral support for the needle 421, and can effectively prevent the needle 421 from deforming or breaking even when subjected to a large insertion force or unexpected lateral pressure, thereby ensuring long-term stable contact and reliable electrical performance. The needle 421 is integrally connected with the limiting portion 422 and is stamped and formed from the same piece of metal sheet, which enhances the structural strength, helps reduce the difficulty of processing, simplifies the production process, and reduces manufacturing costs.

[0031] like Figure 5 As shown, the fixing frame 5 is provided with a plurality of fixing holes 53, the fixing segments 32 are inserted through the fixing holes 53, the hole wall of the fixing holes 53 is provided with positioning blocks 54, the fixing segments 32 are provided with positioning holes 321, and the positioning blocks 54 are embedded in the positioning holes 321. The fixing segments 32 are passed through and fixed in the fixing holes 53, and the interaction between the positioning blocks 54 and the positioning holes 321 effectively enhances the mechanical stability of the connector, and even when subjected to external impact or vibration, the positional relationship between the components can be kept unchanged, reducing interference with current transmission and loosening of the connection. The fixing segments 32 and the pin members 42 of each guide pin 3 are integrated and limitedly installed in the same fixing frame 5, which effectively resists displacement caused by external vibration and ensures the installation stability of the connector.

[0032] like Figure 1-3As shown in 6, 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 guide pin 3 in a compact installation environment, but also ensures sufficient length of the guide pin 3 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.

[0033] like Figure 3 As shown, the insert segment 31 is integrally provided with a plurality of limiting barbs 35 in the width direction and is embedded and fixed with the shell 1 through the limiting barbs 35. These limiting barbs 35 and the shell 1 form a stable embedding fit, reducing the problems of poor contact or loose connection that may be encountered during long-term use.
