Description

Technical Field

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

[0002] In the modern electronics industry, stable connections between circuit boards and other electronic devices are crucial for reliable data transmission. To achieve this, a variety of connector designs have emerged on the market, which enable communication between circuit boards and electronic devices through physical and electrical connections.

[0003] Existing connector technology typically uses a single-particle design, where multiple copper pins are injection-molded at a fixed pitch. Laser welding is then used to stack two thinner copper pins into a single pin to meet specific thickness requirements. These pins are then soldered using automated equipment to connect the circuit board to the electronic device.

[0004] However, existing technologies have some limitations:

[0005] 1. This single-particle connector lacks a positioning function, so only one connector can be welded at a time, resulting in low efficiency. 2. Achieving accurate and efficient single-particle welding requires high-precision automation, which is costly and difficult to maintain. 3. To achieve the required thickness, each copper pin on this connector is laser-welded by stacking two thinner pins, resulting in high processing costs and unstable performance. 4. Short circuits between the pins are prone to occur. Utility Model Content

[0040] Reference Figures 1 to 3 , the utility model provides a connector, comprising: a connector body 1;

[0041] The connector body 1 is also provided with a plurality of positioning holes 101, and adjacent positioning holes 101 are arranged at equal distances to ensure the positioning accuracy when the connector is connected to other electronic devices;

[0042] The connector body 101 has multiple plating areas 2 and pre-cut wires 3 located on top of the plating areas 2. Each plating area 2 corresponds to a positioning hole 101 located above it. Adjacent plating areas 2 are equidistantly spaced. The pre-cut wires 3 facilitate the removal of the positioning portion after the soldering process is completed, simplifying the production process and facilitating the subsequent packaging and sale of individual finished products.

[0043] Each of the electroplating areas 2 is provided with a plurality of conductive areas 201 and an insulating component 202 disposed around the conductive areas 201;

[0044] Each of the conductive areas 201 is provided with a PIN copper pin 4. The insulating assembly 202 is used to insulate two adjacent PIN copper pins 4, ensuring good insulation between adjacent PIN copper pins 4 and preventing short circuits. Each PIN copper pin 4 is provided with two solder points 401, which improves soldering reliability and connector stability. The conductive area 201 is a waist-shaped conductive area with a length of 1.5 mm and a width of 0.3 mm.

[0045] Furthermore, in order to prevent poor electrical conduction caused by oxidation due to long-term exposure of the conductive area 201, the conductive area 201 is electroplated with gold, palladium or platinum. Gold, palladium or platinum have excellent chemical stability. Electroplating these materials can improve the corrosion resistance of the connector; at the same time, they have high electrical conductivity, which can ensure that the connector has excellent conductive performance. The electroplating layer increases the hardness of the conductive area, improves the wear resistance, and extends the service life of the connector.

[0046] Furthermore, the diameter of the positioning hole 101 is 1.5mm, and the center distance between two adjacent positioning holes 101 is 8.0mm; it is used to solve the problem of precise positioning of the connector and the circuit board when multiple welding is achieved at one time. The conventional practice of the production line is to weld a whole line (8 products) at the same time. This circular positioning hole 101 effectively and uniquely plays the role of precise positioning of each product, and efficiently solves the problem of precise positioning of 8 products welded at the same time; the diameter of the positioning hole 1 can be changed to meet the positioning requirements of different devices. The number of positioning holes 1 can also be increased to meet the positioning requirements of different devices, such as adding a positioning hole between two adjacent positioning holes, but the horizontal hole spacing of the added positioning holes must be 8.0mm.

[0047] Furthermore, the insulating component 202 is PCL insulating glue, wherein the PCL insulating glue provides excellent electrical insulation performance to prevent electrical short circuits between adjacent PIN copper needles; PCL (polycaprolactone) is a biodegradable polymer with good environmental adaptability.

[0048] Furthermore, the PIN copper pin 4 is 0.58mm thick and is formed by cold stamping, cold extrusion, and 180-degree bending, followed by stacking to form a double-layer or multi-layer structure. This cold stamping and cold extrusion process is efficient and stable, with a simplified process flow that reduces manufacturing costs and improves product competitiveness. The cold extrusion and reverse bending process enhances the mechanical strength of the copper pin, and its uniform thickness helps ensure a stable electrical connection.

[0049] Furthermore, the number of the plurality of positioning holes 101 is three, and correspondingly, the number of the plurality of electroplating areas 2 is also three. Each electroplating area 2 has eight conductive areas 201, correspondingly, eight PIN copper pins 4, and sixteen solder points 401. The sixteen solder points 401 serve as contact points between the connector and the circuit board during soldering, also known as solder creep points. After the tin on the circuit board melts at high temperatures, it is adsorbed on the solder points, thereby connecting the eight PIN copper pins and the circuit board together to transmit signals to external electronic devices.

[0050] Furthermore, the material of the connector body 1 is H65 copper; the connector body 1 is a plate-like structure and is used for welding connection with a circuit board. H65 copper has sufficient strength and hardness and is suitable as the material of the connector body and can withstand certain mechanical stress. H65 copper has good welding performance and is easy to be welded to a circuit board or other electronic components; using H65 copper as the material of the connector body can provide lower contact resistance and better signal transmission performance.

[0054] The connector body 1 has multiple electroplated areas 2 at its lower portion, each corresponding to a positioning hole 101 above. The electroplated areas 2 are plated with gold, palladium, or platinum. These precious metals provide excellent conductivity and corrosion resistance, ensuring stable and reliable signal transmission.

[0055] Each electroplating area 2 is provided with multiple conductive areas 201, which are the key parts for establishing electrical connections between the connector and external electronic devices; the conductive areas 201 are surrounded by insulating components 202 made of PCL insulating glue. These insulating components 202 effectively isolate adjacent PIN copper needles 4, prevent electrical short circuits and cross interference, and ensure the safety of signal transmission.

[0056] PIN copper pin 4 design:

[0057] Each conductive area 201 houses a PIN copper pin 4 with two solder points 401. The copper pins are 0.58 mm thick and are formed in one step through a stamping, cold extrusion, and 180-degree reverse bending process, resulting in a stable double-layer or multi-layer structure that enhances the pin's mechanical strength and electrical conductivity. The pins align with pads on the circuit board, creating an electrical connection through soldering, enabling data and power transmission.

[0058] Welding and connection of this utility model:

[0059] The connector body 1 is a plate-like structure that facilitates soldering to a circuit board. During the soldering process, the solder joints come into contact with the pads on the circuit board. After heating, the solder melts and fills the gap between the joints and pads, forming a stable solder joint, thereby achieving a secure connection between the connector and the circuit board.
