Description

Technical Field

[0001] This utility model relates to the field of wire harness connector technology, and in particular to a high-efficiency heat dissipation and insulation protection structure for wire harness connectors. Background Technology

[0002] Wire harness connectors are electromechanical components used to achieve detachable connections between wires and between wires and equipment in electrical circuits. They reliably connect the pins of each wire in the wire harness through mechanical connection, realizing the functions of circuit conduction and signal transmission. They play a key role in electrical systems. Currently, the male and female sockets of wire harness connectors are connected by threads to achieve compression and sealing of the connection part of the rubber gasket, so as to prevent external humid air and moisture from entering the pin part and causing damage to the wire harness connector.

[0003] Existing wire harness connectors lack a locking mechanism for their tightening caps. This makes the tightening caps prone to loosening due to external vibrations after connection, causing the sealing connection between the male and female connectors to fail. External moisture and air can easily enter the pins, damaging the wire harness connector. As a result, the connector has poor stability and limited practicality. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Please refer to Figures 1 to 5 Example 1:

[0029] This utility model proposes a high-efficiency heat dissipation and insulation protection structure for wire harness connectors, including: a connector body and a connecting wire harness 3; the connector body is composed of a female connector 1 and a male connector mechanism 2;

[0030] The male connector mechanism 2 includes a male connector 201, a tightening seat 202, a locking disc 203, and an unlocking disc 204. The male connector 201 and the female connector 1 are interlocked, and different connecting wire harnesses 3 are fixedly connected to the sides of the male connector 201 and the female connector 1, respectively. The tightening seat 202 is inserted into the outside of the male connector 201, the locking disc 203 is inserted into the side of the male connector 201, and the unlocking disc 204 is inserted into the outside of the male connector 201. The locking disc 203 and the unlocking disc 204 are located on the inner and outer sides of the tightening seat 202, respectively. The tightening seat 202 is screwed onto the outside of the female connector 1 by threads, and a sealing gasket 4 is provided at the insertion and abutment parts of the female connector 1 and the male connector 201. The male connector 201 can be connected to the female connector 1 via the tightening seat 202, thereby connecting two sections of the wire harness 3 to realize the connection between wires and wires, and between wires and equipment in electrical circuits. After the male connector 201 is inserted into the side of the female connector 1, the tightening seat 202 is screwed onto the outside of the female connector 1. The tightening seat 202 can abut and squeeze the male connector 201 to make it tightly connected to the female connector 1. The sealing gasket 4 will be squeezed by the male connector 201 and the female connector 1, thereby deforming the sealing gasket 4 to seal the connection part of the male connector 201 and the female connector 1, thereby preventing external moisture and other substances from entering the pin part and causing damage to the connector body, thus protecting safety and stability.

[0031] The female connector 1 is provided with heat dissipation fins 101 on its exterior, and the male connector 201 cannot rotate inside the female connector 1. The locking disc 203 cannot rotate inside the male connector 201. The heat dissipation fins 101 can improve the heat dissipation effect of the connector body by increasing the heat dissipation surface area. The heat dissipation fins 101 are located on the exterior of the female connector 1. After absorbing heat through heat conduction, they use their large surface area to contact the air, accelerating the heat convection process. When the air flows through the heat dissipation fins 101, the low-temperature fluid exchanges heat with the high-temperature fins, carrying away the heat and dissipating it into the environment, further improving the stability of the device.

[0032] The locking disc 203 contains a locking top spring 2031, with its two ends abutting against the side of the locking disc 203 and the inside of the connecting seat 201, respectively. Both the locking disc 203 and the tightening seat 202 have locking toothed rings 2032 on their opposite sides, each tooth of which has a right-angled triangular cross-section. When the tightening seat 202 rotates in the direction of loosening, the straight edges of the teeth of the locking disc 203 and the tightening seat 202 engage with each other. During use, the connecting seat mechanism 2 has a locking structure, effectively preventing the tightening seat 202 from loosening due to external vibrations, ensuring stable operation. After the connector body is connected, the locking top spring 2031 locks the connection. The locking tooth rings 2032 of the stop plate 203 and the tightening seat 202 are interlocked. Since the male connector 201 cannot rotate inside the female connector 1, the locking plate 203 cannot rotate inside the male connector 201. Thus, under the snapping action of the straight edges of the two sets of locking tooth rings 2032, the tightening seat 202 cannot rotate in the direction of loosening, thereby ensuring that the connector body is in a stable sealed connection device, which is stable in use. When the tightening seat 202 rotates in the tightening direction, the inclined edges of the teeth of the two sets of locking tooth rings 2032 abut against each other, causing the locking plate 203 to move to one side to avoid the rotation action of the tightening seat 202. This does not hinder the tightening seat 202's connection and pressing action on the male connector 201 and the female connector 1, making operation convenient.

[0033] The unlocking disc 204 has an unlocking stop 2041 on its side, and the block of the unlocking stop 2041 passes through the interior of the tightening seat 202. The unlocking disc 204 also has a reset spring 2042 on its side, with both ends of the reset spring 2042 abutting against the side of the unlocking disc 204 and the side of the tightening seat 202, respectively. Under the action of the reset spring 2042, when the unlocking disc 204 is not pressed by external force, the unlocking stop 2041 separates from the locking tooth ring 2032 of the locking disc 203. In use, the locking structure of the male seat mechanism 2 does not hinder the normal disassembly of the connector body, facilitating subsequent inspection and maintenance. When disassembly is required, the connector body is in a connected position... When disassembling the connector body, simply press the unlocking disc 204 and then rotate the tightening seat 202 in the direction of loosening. When the unlocking disc 204 is pressed, it will compress the reset top spring 2042, and the unlocking disc 204 can drive the unlocking block 2041 to move synchronously. When the unlocking block 2041 moves, it will press the locking disc 203, thereby releasing the jamming relationship between the two sets of locking tooth rings 2032. After that, the tightening seat 202 can freely reverse to complete the disassembly operation of the connector body. Disassembly is convenient. After disassembly, after releasing the unlocking disc 204, the unlocking disc 204 will automatically reset under the action of the reset top spring 2042, in preparation for the subsequent installation and locking of the connector body.

[0034] The working principle of this embodiment is as follows: The male connector 201 can be connected to the female connector 1 through the tightening seat 202, thereby connecting the two sections of the wire harness 3 to realize the connection between wires and wires, and between wires and equipment in the electrical circuit. After the male connector 201 is inserted into the side of the female connector 1, the tightening seat 202 is screwed onto the outside of the female connector 1. The tightening seat 202 can abut and squeeze the male connector 201 to make it tightly connected to the female connector 1. The sealing gasket 4 is squeezed by the male connector 201 and the body of the female connector 1, so that the sealing gasket 4 will deform and seal the connection part of the male connector 201 and the female connector 1, thereby preventing external moisture and other substances from entering the pin part and causing damage to the connector body. The outer surface of the connector 1 is provided with heat dissipation fins 101, which can improve the heat dissipation effect of the connector body by increasing the heat dissipation surface area. The heat dissipation fins 101 are located on the outside of the connector 1. After absorbing heat through thermal conduction, they use their large surface area to contact the air, accelerating the heat convection process. When the air flows through the heat dissipation fins 101, the low-temperature fluid exchanges heat with the high-temperature fins, carrying away the heat and dissipating it into the environment. The male connector mechanism 2 has a locking structure, which can effectively prevent the tightening seat 202 from loosening due to external vibration and other factors during use, ensuring stable use. After the connector body is connected, under the action of the locking top spring 2031, the locking disc 203 and the locking tooth ring 2032 of the tightening seat 202 are interlocked. Since the male connector 201 cannot rotate inside the female connector 1, the locking disc 203 cannot rotate inside the male connector 201. Therefore, under the locking action of the straight edges of the two sets of locking toothed rings 2032, the tightening seat 202 cannot rotate in the direction of loosening. This ensures that the connector body is in a stable sealed connection device, ensuring stable operation. Furthermore, when the tightening seat 202 rotates in the tightening direction, the inclined edges of the teeth of the two sets of locking toothed rings 2032 abut against each other, causing the locking disc 203 to move to one side to avoid the rotation of the tightening seat 202. This does not obstruct the tightening action of the tightening seat 202 on the male connector 201 and the female connector 1. The locking structure of the male connector mechanism 2 does not hinder the normal disassembly of the connector body, facilitating easy disassembly. For subsequent inspection and maintenance, when it is necessary to disassemble the connector body in the connecting device, simply press the unlocking disc 204 and then rotate the tightening seat 202 in the direction of loosening. When the unlocking disc 204 is pressed, it will compress the reset top spring 2042, and the unlocking disc 204 can drive the unlocking block 2041 to move synchronously. When the unlocking block 2041 moves, it will press the locking disc 203, thereby releasing the jamming relationship between the two sets of locking toothed rings 2032. After that, the tightening seat 202 can freely reverse to complete the disassembly operation of the connector body. Disassembly is convenient. After disassembly, after releasing the unlocking disc 204, the unlocking disc 204 will automatically reset under the action of the reset top spring 2042, in preparation for the subsequent installation and locking of the connector body.
