Description

Technical Field

[0001] This utility model relates to the field of connectors, specifically a connector that is easy to install. Background Technology

[0002] Female headers are a type of electronic connector widely used in electronic products. They are typically used with pin headers and consist of multiple neatly arranged sockets to receive the pins of the pin header, enabling board-to-board connections. Female headers generally consist of a housing, pins, and sockets. The housing is usually made of insulating materials such as plastic, while the pins and sockets are typically made of metal. The working principle of a female header is to transmit electrical signals through the contact between the pins and sockets, thereby achieving the transmission of current or signals. Due to their easy insertion and removal design, female headers are widely used in devices that require frequent disassembly and reassembly.

One end of the first groove has a boss, and the bottom of the first groove has a first pin hole that communicates with the first groove and the second groove. A pin block is fixed inside the first groove. A third groove corresponding to the boss is provided on the pin block for cooperation. Blind holes are provided on the two opposite sidewalls of the pin block corresponding to the threaded holes. The pin block has a second pin hole. By using a detachable pin block, and by selecting pin blocks of different thicknesses according to the length of the pin, the pin is protected and easily replaced.

[0004] The existing female header connectors are fixed to the circuit board by soldering the lower end of the pin header, which makes the installation of the female header connectors relatively troublesome. At the same time, the disassembly is also troublesome when the female header connector is damaged and repaired. Therefore, there is an urgent need in the market to develop a connector that is easy to install to help people solve the existing problems. Utility Model Content

[0009] Preferably, the four second L-shaped connecting plates at the lower end of the busbar are all fixed to the circuit board mounting position by first screws passing through the rectangular pressure ring and the second L-shaped connecting plates in sequence.

[0010] Preferably, both the front and rear ends of the lower end face of the rectangular pressure ring are in contact with the upper end face of the L-shaped connecting part at the lower end of the arrayed pins.

[0011] Preferably, the lower end of the sub-row is fixedly provided with a plug-in part, and the main row and the sub-row are connected by inserting the plug-in part into the plug-in slot for limiting connection.

[0012] Preferably, elastic fixing plates are fixedly connected to the upper middle part of both ends of the busbar.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a connector that is easy to install, including a busbar 1 and a daughter busbar 4. The upper surface of the busbar 1 is provided with a insertion groove 101. Multiple pins 2 are arrayed on the lower surface inside the insertion groove 101. All pins 2 are fixedly connected to the lower surface of the insertion groove 101 inside the busbar 1. The lower ends of the pins 2 extend out of the lower surface of the busbar 1 and are fixedly connected to L-shaped connecting portions 201. First L-shaped connecting plates 102 are fixedly connected to both sides of the lower surface of the busbar 1. The front and rear ends of the lower surface of the busbar 1 are connected to... Each busbar 1 is fixedly connected with a second L-shaped connecting plate 103. A rectangular pressure ring 3 is provided on the outer side of the busbar 1 at the upper ends of the two first L-shaped connecting plates 102 and the four second L-shaped connecting plates 103. The two first L-shaped connecting plates 102 at the lower end of the busbar 1 are connected to the circuit board mounting position by second screws 302, which pass through the rectangular pressure ring 3 and the first L-shaped connecting plate 102 in sequence, and are then threadedly fixed to the circuit board. The four second L-shaped connecting plates 103 at the lower end of the busbar 1 are connected to the circuit board mounting position by first screws 301, which pass through the first screws 301 in sequence. The rectangular pressure ring 3 and the second L-shaped connecting plate 103 are then threaded and fixed to the circuit board. The rectangular pressure ring 3 and the two first L-shaped connecting plates 102 are fixed to the circuit board using second screws 302, thus fixing the busbar 1. Then, the front and rear ends of the rectangular pressure ring 3 and the second L-shaped connecting plate 103 are fixed to the circuit board using first screws 301. Both the front and rear ends of the lower end face of the rectangular pressure ring 3 are in contact with the upper end face of the lower L-shaped connecting part 201 of the arrayed pin header 2. The second L-shaped connecting plate 103... When fixed, the front and rear ends of the rectangular pressure ring 3 will simultaneously press down on the upper surface of the L-shaped connecting part 201 at the lower end of the arrayed pin header 2, thereby causing the L-shaped connecting part 201 to deform slightly downward and fit with the electrical connection points arrayed on the circuit board, realizing electrical connection between the pin header 2 and the circuit board. There is no need to solder the L-shaped connecting part 201 and the circuit board in the traditional way, which improves production efficiency. At the same time, by removing the first screw 301 and the second screw 302, the busbar 1 can be separated from the circuit board, which is convenient for maintenance and replacement of the busbar 1.

[0024] Please see Figure 1-3 The sub-row 4 is located on the upper end of the main row 1. The lower end of the sub-row 4 is fixedly provided with a plug-in part 401. The main row 1 and the sub-row 4 are connected by inserting the plug-in part 401 into the plug-in slot 101 for limiting connection. The upper middle part of the upper end of both sides of the main row 1 is fixedly connected with an elastic fixing piece 104. The upper end of the two elastic fixing pieces 104 extends out of the upper end of the main row 1 and a trapezoidal limiting block 105 is fixedly provided on the inner end face of each. The upper end of both sides of the sub-row 4 is provided with a rectangular slot 402. After the sub-row 4 and the main row 1 are plugged in, the trapezoidal limiting blocks 105 on the two elastic fixing pieces 104 slide into the two rectangular slots 402 respectively to limit the distance between the sub-row 4 and the main row 1. By pulling the elastic fixing pieces 104 outward, the trapezoidal limiting blocks 105 are disengaged from the rectangular slots 402, and the sub-row 4 can be pulled out upward.

[0025] Working principle: In use, firstly, align the busbar 1 with the corresponding position on the circuit board via the first L-shaped connecting plate 102 and the second L-shaped connecting plate 103 at its lower end. Then, use the second screw 302 to pass through the rectangular pressure ring 3 and the first L-shaped connecting plate 102 to fix them to the circuit board. Next, use the first screw 301 to pass through the rectangular pressure ring 3 and the second L-shaped connecting plate 103 to further fix them to the circuit board. In this way, the rectangular pressure ring 3 ensures that the L-shaped connecting part 201 at the lower end of the pin 2 is in close contact with the electrical connection point on the circuit board during the tightening process, achieving electrical connection without soldering. Next, align the plug-in part 401 at the lower end of the sub-busbar 4 with the plug-in slot 101 at the upper end of the busbar 1 and insert it until the rectangular slots 402 on both sides of the sub-busbar 4 meet and engage with the trapezoidal limiting blocks 105 on the elastic fixing plates 104 on both sides of the busbar 1, completing the stable connection between the sub-busbar 4 and the busbar 1. When disassembly or repair is required, simply reverse the operation. First, pull the elastic fixing piece 104 to make the trapezoidal limiting block 105 come out of the rectangular slot 402, which can easily separate the sub-bar 4 and the busbar 1. Then, loosen the first screw 301 and the second screw 302 one by one to remove the busbar 1 from the circuit board. The entire installation and disassembly process is simple and quick, which greatly improves work efficiency.
