Description

Technical Field

[0002] Electrical connector contacts are the core components of electrical connectors that enable circuit connection and signal transmission. They play a crucial role in the entire electrical connection system. Electrical connector contacts are the parts in electrical connectors used for direct contact, conduction of current or transmission of signals. They are also called contacts or pins and sockets. In the circuit system, they undertake the important functions of current conduction and signal transmission, just like a "bridge" in the circuit, ensuring reliable transmission of electrical energy and signals between different devices and components.

[0003] In high-precision fields such as aerospace, high-speed trains, and industrial automation, the reliability and vibration resistance of electrical connectors are crucial. For contact components with leaf spring structures in electrical connectors, due to structural limitations, the electrical performance parameters and product stability under harsh operating conditions after contact component mating are important indicators that determine the quality of product performance. Therefore, the vibration-resistant design of the contact points after mating is of paramount importance.

[0004] However, the existing electrical connector contacts are not conducive to ensuring the stability of the electrical connector contacts. When faced with severe vibration and frequent plugging and unplugging, traditional electrical connector contacts are prone to problems such as poor contact and unstable signal transmission, which seriously affect the normal operation of the system.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0033] This invention provides a highly reliable and vibration-resistant claw spring type electrical connector contact, which helps ensure the stability of the contact during use. When faced with severe vibration and frequent insertion and removal, it can avoid problems such as poor contact and unstable signal transmission, thus helping to ensure the normal operation of the system. The elastic claw spring has the advantages of simple structure, high shock resistance, durability, reliability, and high stability. Furthermore, the multiple elastic claws in the elastic claw spring and the redundant contact design of the elastic claw spring can maintain more than 80% conductivity even after a single point failure.

[0034] Please see Figure 1-8 A highly reliable and vibration-resistant claw spring type electrical connector contact includes a connector contact body 1. A claw spring hole 8 is formed in the middle of one end of the connector contact body 1. An elastic claw spring 7 is inserted and installed in the claw spring hole 8 on the connector contact body 1. The elastic claw spring 7 includes a plurality of elastic claws arranged at intervals along the circumferential direction at one end. The included angle between adjacent elastic claws on the elastic claw spring 7 is 60° to 90°. A plurality of arc-shaped... The outer side of the elastic plate 5, which is located outside the elastic claw spring 7, is fitted with a cylindrical claw spring hole sleeve 9. This helps to ensure the stability of the contact parts of the electrical connector during use. When faced with severe vibration and frequent insertion and removal, it can avoid problems such as poor contact and unstable signal transmission, and help ensure the normal operation of the system. The elastic claw spring 7 has the advantages of simple structure, high shock resistance, durability and reliability, and high stability. Moreover, the multiple elastic claws in the elastic claw spring 7 and the redundant contact design of the elastic claw spring 7 can still maintain more than 80% conductivity after a single point failure.

[0035] In this design, each elastic claw on the elastic claw spring 7 deforms independently and contacts the external pins that need to be inserted through an arc-shaped transition section. The elastic claws on the elastic claw spring 7 achieve 360° full-circumferential redundant contact with the external pins that need to be inserted. An elastic block 6 is fixed at the end of the arc-shaped elastic plate 5 away from the main body of the electrical connector contact. A matching slot 10 is opened on the inner ring surface of the cylindrical claw spring hole sleeve 9 corresponding to the elastic block 6. The part of the cylindrical claw spring hole sleeve 9 corresponding to the elastic block 6 and the slot 10 is in a pressable and deformable state. A retaining ring 11 is fixed on the surface of the cylindrical claw spring hole sleeve 9 away from the main body of the electrical connector contact. An annular pad 12 is fixed on the side surface of the retaining ring 11 near the cylindrical claw spring hole sleeve 9 located inside the cylindrical claw spring hole sleeve 9. The side surface of the annular pad 12 near the elastic claw spring 7 is in contact with the corresponding position on the elastic claw spring 7. The annular pad 12 helps to block and limit the elastic claw spring 7.

[0036] A first insertion groove 2 is provided in the middle of the electrical connector contact body 1 near the elastic claw spring 7. The first insertion groove 2 on the electrical connector contact body 1 is connected to the claw spring hole 8 on the electrical connector contact body 1. The inner ring diameter of the first insertion groove 2 on the electrical connector contact body 1 is smaller than the inner ring diameter of the claw spring hole 8 on the electrical connector contact body 1. A second insertion groove 3 is provided in the middle of the electrical connector contact body 1 away from the elastic claw spring 7. An arc-shaped cut surface 13 is provided on the upper side of the electrical connector contact body 1 near the second insertion groove 3.

[0037] A positioning hole 4 is provided on the upper side of the contact body 1 near the first insertion slot 2, corresponding to the first insertion slot 2. The positioning hole 4 on the contact body 1 is connected to the first insertion slot 2 on the contact body 1. The positioning hole 4 facilitates the positioning of the plug inserted into the first insertion slot 2 by means of an external positioning pin. An external threaded cylinder 14 is rotatably mounted on the outer side of the middle of the outer ring surface of the contact body 1 through a bearing. A rotating ring 15 is fixed on the surface of the external threaded cylinder 14 near the first insertion slot 2. The rotating ring 15 helps to rotate the external threaded cylinder 14.

[0038] A fixing block 22 is fixed on the upper side of the outer ring surface of the contact body 1 of the electrical connector, on the side of the rotating ring 15 away from the external threaded cylinder 14. A limiting groove 23 is opened in the middle of the upper side of the fixing block 22. A limiting block 21 is slidably installed in the limiting groove 23 on the fixing block 22 in the horizontal direction. A resistance pad 24 that fits tightly in the limiting groove 23 is fixed on the outer side of the limiting block 21. The resistance pad 24 helps to increase the frictional resistance between the limiting block 21 and the limiting groove 23. A connecting block 20 is fixed on the upper surface of the limiting block 21. A push-pull block 19 is fixed on the upper surface of the connecting block 20. A horizontal limiting rod 18 is fixed in the middle of the surface of the push-pull block 19 near the rotating ring 15. A number of limiting holes 17 that match the limiting rod 18 are opened at intervals along the circumferential direction on the rotating ring 15. A number of protrusions 16 are fixed at intervals along the circumferential direction on the outer ring surface of the rotating ring 15. The protrusions 16 can prevent slippage on the outer ring surface of the rotating ring 15.

[0039] The working principle of this invention is as follows: During use, the push-pull block 19 is pulled, causing it to move away from the rotating ring 15. When the push-pull block 19 moves, it can drive the limiting rod 18 to move, causing the limiting rod 18 to disengage from the limiting hole 17 on the rotating ring 15. The limiting rod 18 will then release its limitation on the rotating ring 15, aligning the external threaded cylinder 14 on the outer side of the middle of the outer ring surface of the electrical connector contact body 1 with the external position where it needs to be fixed and installed. Furthermore, the rotating ring 15 is rotated by the protrusion 16, which provides anti-slip properties on the outer ring surface of the rotating ring 15, facilitating stable rotation of the rotating ring 15. When the rotating ring 15 rotates, it can drive the external threaded cylinder 14 to rotate, causing the external threaded cylinder 14 to be threaded into the external position where it needs to be installed, thereby fixing and installing the electrical connector contact body 1.

[0040] Further pushing the push-pull block 19 toward the rotating ring 15, the push-pull block 19 moves and drives the limiting rod 18 to move, so that the limiting rod 18 is inserted into the corresponding limiting hole 17 on the rotating ring 15. The push-pull block 19 can position the rotating ring 15 through the limiting rod 18 and the limiting hole 17, so as to limit the rotation between the rotating ring 15 and the electrical connector contact body 1, which can prevent the electrical connector contact body 1 from rotating and misaligned, and help to use the electrical connector contact body 1 stably. When the push-pull block 19 moves, it will drive the limiting block 21 and the resistance pad 24 to move along the limiting groove 23 on the fixed block 22 through the connecting block 20. The resistance pad 24 can increase the frictional resistance between the fixed block 22 and the limiting block 21 in the upper limit groove 23, so as to position the push-pull block 19 after it moves.

[0041] Further, the plugs that need to be connected to the outside are inserted into the first insertion slot 2 and the second insertion slot 3 on the contact body 1 of the electrical connector. When the external pin is inserted into the first insertion slot 2, the pin will pass through the inside of the elastic claw spring 7. The elastic claw on the elastic claw spring 7 will be squeezed and clamped to connect the pin. The contact body 1 of the electrical connector can limit the cylindrical claw spring hole sleeve 9 through the arc-shaped elastic plate 5, the elastic block 6 and the slot 10. The cylindrical claw spring hole sleeve 9 can fix and limit the retaining ring 11 and the annular pad 12, which facilitates the stable use of the retaining ring 11 and the annular pad 12. The annular pad 12 can block and limit the elastic claw spring 7, which helps to stabilize the use of the elastic claw spring 7 and ensures the vibration resistance of the elastic claw spring 7.

[0042] When the elastic claw spring 7 needs to be disassembled, press the position of the elastic locking block 6 on the cylindrical claw spring hole sleeve 9, so that the elastic locking block 6 and the arc-shaped elastic plate 5 deform inward, so that the cylindrical claw spring hole sleeve 9 moves away from the electrical connector contact body 1. After the cylindrical claw spring hole sleeve 9 is removed, the cylindrical claw spring hole sleeve 9 will drive the retaining ring 11 and the annular pad 12 to be removed, so that the annular pad 12 can no longer block and limit the elastic claw spring 7, so that the elastic claw spring 7 can be disassembled and removed. When the elastic claw spring 7 needs to be assembled, place the elastic claw spring 7 into the claw spring hole 8 on the electrical connector contact body 1, and reset the cylindrical claw spring hole sleeve 9 and put it on the outside of the elastic locking block 6 and the arc-shaped elastic plate 5, so that the elastic locking block 6 is locked into the slot 10 on the cylindrical claw spring hole sleeve 9 to limit the cylindrical claw spring hole sleeve 9, thus completing the assembly of the elastic claw spring 7.

[0043] During use, it helps to ensure the stability of the contacts of this electrical connector. When faced with severe vibration and frequent plugging and unplugging, it can avoid problems such as poor contact and unstable signal transmission, which helps to ensure the normal operation of the system. The elastic claw spring 7 has the advantages of simple structure, high shock resistance, durability and reliability, and high stability. Moreover, the multiple elastic claws in the elastic claw spring 7 and the redundant contact design of the elastic claw spring 7 can still maintain more than 80% conductivity after a single point failure.

[0044] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
