Description

Technical Field

[0001] This utility model relates to the field of electronic device technology, specifically to a ground wire integrated electrical connector. Background Technology

[0002] Grounding connectors are suitable for electrical equipment that requires multiple grounding terminals, especially in situations where electromagnetic shielding requirements are high and space is limited, such as electronic equipment, communication equipment, and industrial automation equipment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model provides a technical solution:

[0028] A ground-connected electrical connector, comprising:

[0029] The electrical connector body 1 has a socket 2 at one end and a locking frame 3 at the other end.

[0030] The first circuit board 4 and the second circuit board 5 are provided with a locking plate 6 at one end of the first circuit board 4 and the second circuit board 5. The locking plate 6 is locked in the locking frame 3 and the first circuit board 4 and the second circuit board 5 are locked together. The two locking plates 6, the first circuit board 4 and the second circuit board 5 are each provided with an L-shaped plate 10 opposite to each other, and the two locking plates 6, the first circuit board 4 and the second circuit board 5 are each provided with an L-shaped groove 11 for the L-shaped plate 10 to be locked.

[0031] When connecting the first circuit board 4 and the second circuit board 5, the L-shaped plates 10 disposed opposite to each other on the first circuit board 4 and the second circuit board 5 are engaged in the L-shaped groove 11, which can engage and connect the first circuit board 4 and the second circuit board 5. Disassembly is possible in case of damage, and the different functions of the connector can be designed as independent modules. In this way, when a module fails, it can be replaced or repaired individually without affecting the use of the entire connector. This ensures standardized interfaces between modules, facilitating quick connection and disassembly, which not only improves maintenance efficiency but also reduces maintenance costs.

[0032] Furthermore, both sides of the two locking plates 6 are provided with arc-shaped protrusions 12, and the locking frame 3 is provided with arc-shaped grooves 13 for the arc-shaped protrusions 12 to engage.

[0033] When connecting the first circuit board 4 and the second circuit board 5 to the electrical connector body 1, the locking plate 6 is locked in the locking frame 3, and the arc-shaped protrusions 12 on both sides of the locking plate 6 are locked in the arc-shaped groove 13, so that the locking plate 6 can be locked and fixed in the locking frame 3, and the first circuit board 4 and the second circuit board 5 are connected to the electrical connector body 1.

[0034] The cable body 8 has one end connected to the first circuit board 4 and the second circuit board 5. The connector body 1 is fitted with a connecting cover 9. The connecting cover 9 and the cable body 8 are connected by a snap-fit ​​assembly.

The first triangular blocks 23 and the second triangular blocks 24 are snap-fitted together.

[0035] When the cable body 8 is engaged with the electrical connector body 1, the connecting cover 9 moves on the electrical connector body 1. Due to the elasticity of the lever 22, the inclined surfaces of the first triangular block 23 and the second triangular block 24 are in contact with each other, pushing the connecting cover 9. The lever 22 deforms, and the right-angled surface of the first triangular block 23 is in contact with the right-angled surface of the second triangular block 24, thus engaging the connecting cover 9 with the cable body 8. The connecting cover 9 can also protect the first circuit board 4 and the second circuit board 5.

One end of it is provided with a ground terminal body 14, which can be connected to a corresponding ground terminal body 14 on the first circuit board 4, realizing electrical conduction between the electrical connector body 1 and the first circuit board 4 on the grounding line, and providing a reliable grounding path for the entire system; at the same time, one end of the electrical connector body 1 is also provided with a signal terminal body 16, which is connected to a signal terminal pad 17 on another locking plate 6, realizing the electrical connection of the signal terminal.

[0038] One end of the cable body 8 is equipped with a grounding cable 18, which is connected to the ground pad 19 on the first circuit board 4, further enhancing the stability and reliability of the system grounding. This design ensures that during operation, any static electricity or other interference currents that may be generated can be promptly introduced to the ground, guaranteeing the normal operation of the equipment and the safety of personnel.

[0039] In addition, the other end of the cable body 8 is provided with a signal cable body 20, which is connected to the signal cable pad 21 on the second circuit board 5. Through this connection method, signal transmission between the cable body 8 and the second circuit board 5 is realized, enabling the device to accurately receive and process various signal commands and complete corresponding functional operations;

[0040] The connection layout between the electrical connector body 1, the cable body 8, and the circuit board rationally plans the grounding line and signal transmission line, which not only ensures the electrical safety of the system, but also ensures the accuracy and stability of signal transmission, laying a solid foundation for the normal operation of the entire electronic device.
