Description

Technical Field

[0001] The utility model relates to the technical field of connecting accessory equipment, in particular to a pin and sleeve structure for circuits. Background Art

[0002] Pin sockets, also known as connectors, are devices that connect two active devices. They are usually installed between blocked or isolated circuits in a circuit to build a conductive bridge, transmit current or signals, and enable the circuit to achieve its intended function. The old pin socket mating parts require a beryllium bronze inner mesh ring to reduce the electrical gap and achieve the function of low resistance. However, when using an inner mesh ring of this structure, the contact resistance between the pin and the inner mesh ring is high. A high contact resistance value will increase energy consumption, thereby increasing costs. In addition, the old pin socket mating parts also require a stainless steel retaining ring to achieve a retaining function, which increases the number of accessories and complicates the installation process.

[0003] After searching, a Chinese patent with publication number CN217507803U discloses a new type of pin-socket fitting, including a pin and a socket, wherein a plug-in portion is provided at one end of the pin, a socket hole is provided in the socket, the plug-in portion can be inserted into the socket hole, a mesh ring portion is integrally formed on the socket, the mesh ring portion is bent and protruded into the socket hole, when the plug-in portion is inserted into the socket hole, the mesh ring portion conflicts with the plug-in portion, the pin is further provided with a limiting step for limiting the depth of the plug-in portion inserted into the socket hole, a large diameter portion is further provided at the end of the limiting step away from the plug-in portion, a plurality of pin spring pieces are provided on the large diameter portion, and the large diameter portion is provided with a plurality of pin spring pieces. A pin connecting part is provided at one end of the part, and a pin clip is provided at one end of the pin connecting part. The new pin-socket matching part has a plug-in part at one end of the pin, and a socket hole is provided in the socket, and the plug-in part can be inserted into the socket hole. A mesh ring part is also integrally formed on the socket, and the mesh ring part is bent and protruded into the socket hole. When the plug-in part is inserted into the socket hole, the mesh ring part conflicts with the plug-in part. By selecting new materials, the mesh ring is made on the body to replace the beryllium bronze inner mesh ring, so that the inner mesh ring and the socket are integrally formed, thereby greatly reducing the electrical gap and achieving the function of low resistance. At the same time, the number of accessories is reduced, the cost is saved, and the assembly is simplified.

[0004] While the above solution significantly reduces electrical clearance, achieving low resistance, and reducing the number of components, saving costs, and simplifying assembly, the mesh ring, when pressed against the plug over time, accelerates the loss of elasticity in the mesh sleeve, making it impossible to ensure a secure connection between the pin and the sleeve. To address this, we have developed a circuit pin-sleeve structure to address these issues. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 1-7 As shown, the utility model provides a technical solution: a pin and socket structure for a circuit, comprising a socket 1 and a pin 4. A first wiring mechanism 2 is provided on the left side of the socket 1, and the first wiring mechanism 2 comprises a first wire pressing frame 201 and a first screw 205. The right side of the first wire pressing frame 201 is fixedly connected to the left end of the socket 1, and a first wire pressing cavity 202 is provided on the right side of the first wire pressing frame 201.

[0029] Here, the material of the first wire pressing plate 204 is preferably copper, and the first wire pressing plate 204 is connected to the conductive component inside the socket 1. By inserting the socket end terminal into the first wire pressing cavity 202 and below the first wire pressing plate 204, and then controlling the first screw 205 to rotate clockwise, the first wire pressing plate 204 is driven to slide backward inside the first wire pressing cavity 202 and tighten the terminal terminal, thereby achieving the purpose of quickly connecting the socket end circuit of this device.

[0030] A socket 3 is provided inside the socket 1, a plug 5 is provided on the left side of the pin 4, and a clamping mechanism 6 is provided on the outside of the plug 5. The clamping mechanism 6 includes a clamping frame 601, the left end of the clamping frame 601 is fixedly connected to the right end of the socket 1, and a clamping cavity 602 is provided at the right end of the clamping frame 601. The inner side wall of the clamping cavity 602 is provided with a clamping groove 603, and two groups of mutually symmetrical clamping plates 604 are clamped inside the clamping groove 603. The right sides of the two groups of clamping plates 604 are fixedly connected to the first connecting ring 605, the right side of the first connecting ring 605 is fixedly connected to the left end of the pin 4, and the right side of the first connecting ring 605 is provided with a first through hole 606.

[0031] Here, the socket 1 and the socket 3 together constitute a socket component, and the pin 4 and the plug 5 together constitute a pin component.

By controlling the insertion of the clamping plate 604 into the clamping cavity 602, the clamping plate 604 is given an extruding force. When the clamping plate 604 is fully inserted into the inside of the clamping cavity 602, the elastic action of the clamping plate 604 makes the clamping plate 604 quickly clamped into the inside of the clamping groove 603, so that the plug 5 can be inserted into the inside of the first wiring mechanism 2, thereby achieving the purpose of efficiently docking the pin and socket of this device.

[0032] An anti-slip mechanism 7 is provided on the outside of the clamping mechanism 6, and the anti-slip mechanism 7 includes an anti-slip cylinder 701, the right end of the anti-slip cylinder 701 is fixedly connected to the left end of the pin 4, and an anti-slip cavity 702 is provided at the right end of the anti-slip cylinder 701, and the inner side wall of the anti-slip cavity 702 is slidably connected to the outer surface of the clamping frame 601 and the first connecting ring 605.

[0033] The material of the limit plate 704 here is preferably alloy memory metal, and when the limit plate 704 is fully inserted into the limit groove 703, the protruding block on the right side of the limit plate 704 can be clamped in the circular groove of the limit groove 703, and the connection of the pin and sleeve can drive the limit plate 704 to be inserted into the limit groove 703, thereby giving the limit plate 704 an extruding force. When the limit plate 704 is fully inserted into the limit groove 703, the elastic action of the limit plate 704 makes the limit plate 704 quickly clamped in the limit groove 703, thereby achieving the purpose of preventing the pin and sleeve of this device from falling off.

[0034] A second wiring mechanism 8 is provided on the right side of the pin 4, and the second wiring mechanism 8 includes a second wire pressing frame 801 and a second screw 805.

[0035] Here, the material of the second wire pressing plate 804 is preferably copper, and the second wire pressing plate 804 is connected to the conductive component inside the pin 4. By inserting the pin end terminal connector into the second wire pressing cavity 802 and placing it below the second wire pressing plate 804, and then controlling the second screw 805 to rotate clockwise, the second wire pressing plate 804 is driven to slide backward inside the second wire pressing cavity 802 and tighten the terminal connector, thereby achieving the purpose of quickly connecting the pin end circuit of this device.

[0036] Working principle: When docking the pin and socket, the clamping plate 604 is controlled to be inserted into the inside of the clamping cavity 602, thereby giving the clamping plate 604 an extruding force. When the clamping plate 604 is fully inserted into the inside of the clamping cavity 602, the elastic action of the clamping plate 604 makes the clamping plate 604 quickly snap into the inside of the clamping groove 603, so that the plug 5 can be inserted into the inside of the first wiring mechanism 2, achieving the purpose of efficient docking of the pin and socket of this device. Through the docking of the pin and socket, the limiting plate 704 is driven to be inserted into the inside of the limiting groove 703, thereby giving the limiting plate 704 an extruding force. When the limiting plate 704 is fully inserted into the inside of the limiting groove 703, the elastic action of the limiting plate 704 makes the limiting plate 704 quickly snap into the inside of the limiting groove 703, achieving the purpose of docking the pin and socket of this device.

When connecting the wires of the pin part, the pin end terminal is inserted into the second wire pressing cavity 802 and is below the second wire pressing plate 804, and then the second screw 805 is controlled to rotate clockwise, thereby driving the second wire pressing plate 804 to slide backward inside the second wire pressing cavity 802 and press the wire end tightly, thereby achieving the purpose of quickly connecting the pin end circuit of the device.
