Description

Technical Field

[0001] This invention relates to the field of power component technology, specifically to a tensile-resistant and compression-resistant miniature threaded safety electrical connector. Background Technology

[0002] In modern electronic devices and electrical systems, electrical connectors, as key components for circuit connections, directly impact the stability and reliability of the entire system. With the rapid development of electronic technology, devices are increasingly miniaturized and integrated, placing higher demands on electrical connectors. They not only need excellent conductivity but also must ensure connection stability and security in complex operating environments. Traditional miniature threaded electrical connectors have revealed numerous problems in practical applications, severely restricting their use in high-end electronic devices and critical electrical systems.

[0003] During equipment operation, electrical connectors are inevitably subjected to various external forces, such as vibration and tension. Traditional miniature threaded electrical connectors are prone to loosening under these forces, leading to poor contact and affecting the normal conduction of the circuit. In the aerospace field, aircraft experience intense vibrations and impacts during flight; loosening of traditional electrical connectors can cause serious electrical faults, threatening flight safety.

[0004] When electrical connectors are compressed, their internal structure is easily deformed and damaged. Inside some compact electronic devices, where space is limited between components, electrical connectors may be subjected to compression from surrounding parts. Traditional electrical connectors lack effective compression resistance design; once compressed, this can lead to problems such as insulation layer cracking and pin deformation, potentially causing short circuits or open circuits and affecting the normal operation of the device.

[0005] Some traditional electrical connectors lack adequate insulation, posing safety hazards during use. Workers operating or maintaining the equipment may suffer electric shock from contact with live parts. Furthermore, the lack of corresponding safety protection mechanisms when connectors malfunction, such as overheating or short circuits, could lead to more serious accidents like fires.

[0006] Traditional miniature threaded electrical connectors often fail to adequately consider actual usage needs and environmental factors in their structural design. Connection and disassembly are inconvenient, time-consuming, and labor-intensive. Furthermore, their internal layout hinders heat dissipation; under high-load operating conditions, heat accumulation may accelerate component aging and reduce the connector's lifespan. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a tensile and compression-resistant miniature threaded safety electrical connector. This solves the problems of unstable electrical connection, poor device connection, and inability to withstand axial tension, which leads to easy damage of the connector.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a tensile and compression-resistant miniature threaded safety electrical connector, comprising an insulating shell, an outer casing fixedly connected to the outer surface of the insulating shell, a connecting device sleeved on the bottom of the insulating shell, an adapter compression device fixedly connected inside an opening on the surface of the insulating shell, a limiting ring plate fixedly connected to the bottom of the outer casing, an outer ring plate fixedly connected to the outer surface of the top of the insulating shell, a connecting rod fixedly connected to the top of the adapter compression device, a connecting end fixedly connected to the top of the connecting rod, and a connecting threaded rod fixedly connected to the outer surfaces between the opposing surfaces of the connecting rod. By using the connecting threaded rod, during electrical connection, the connecting device can be directly rotated counterclockwise through the connecting threaded rod into the device, achieving a stable electrical connection. Simultaneously, the insulating shell and the outer casing effectively seal the electrical connection components, preventing electric shock to workers during operation.

[0009] Preferably, the adapter extrusion device includes a connecting rod, the bottom of which is fixedly connected to the outer surface of the insulating shell, both sides of the outer surface of the connecting rod are fixedly connected to the inner wall of the opening on the surface of the insulating shell, the top of the connecting rod is fixedly connected to the bottom of the connecting rod, and the connecting rod has an internal groove, and an inner protruding pressure rod and a locking plate are fixedly connected inside the internal groove.

[0010] Preferably, the inner convex pressure rod penetrates the insulating shell and extends to the outside, and the inner convex pressure rod is pressed and adapted to the inner surface of the outer shell. The locking plate is disposed in the inner cavity of the insulating shell, and the outer surface of the locking plate has a side groove, the side of which is designed to connect a connecting spring. When the sleeve device is screwed into the insulating shell, the connecting rod, through its own elasticity, cooperates with the locking plate to achieve a close fit with the sleeve device. At the same time, in case of excessive compression, the inner convex pressure rod can press the outer shell outward to prevent internal structural damage and improve service life.

[0011] Preferably, the sleeve device includes a sleeve housing, an external collar is fixedly connected to the outer surface of the sleeve housing, an elastic pull rod is fixedly connected to the top of the external collar, and a limit ring is fixedly connected to the top of the elastic pull rod.

[0012] Preferably, an inner hook rod is fitted into the recessed hole at the top of the sleeve housing. A side wiring is fixedly connected to the bottom of the inner hook rod, and a pressure-resistant device is fixedly connected to the bottom of the side wiring. The pressure-resistant device is fitted onto the bottom of the sleeve housing. A side fixing plate is fixedly connected between the opposite faces of the inner hook rod, and an inner spring plate is fixedly connected to the inner surface of the side fixing plate. The inner spring plate on the side of the side fixing plate is fitted into the connecting threaded rod. The inner spring plate can lock the connecting threaded rod during rotation, achieving a connection locking effect. At the same time, the outer limiting ring and elastic pull rod can protect the connector when the external environment pulls on the connector.

[0013] Preferably, the pressure-resistant device includes a connecting block, the outer surface of which is fitted onto the bottom of the sleeve shell, an inner plate is fixedly connected to the top of the outer surface of the connecting block, and an elastic block is fixedly connected to the surface of the inner plate.

[0014] Preferably, a buckle plate is fixedly connected to the top of the internal mounting plate, and the outer surface of the elastic block is fixedly connected to the bottom end of the side wiring. The buckle plate and the opposite surfaces of the side wiring are pressed together. When the electrical connector is subjected to axial tension, the buckle plate can resist the side wiring, improving the device's pressure resistance under axial force.

[0015] This invention provides a tensile and compression-resistant miniature threaded safety electrical connector. It offers the following advantages:

[0016] (i) The tensile and compression resistant miniature threaded safety electrical connector, through the setting of the connecting thread rod, can directly turn the socket device counterclockwise into the device through the connecting thread rod when connecting it, so as to achieve a stable connection effect. At the same time, the insulating shell and the outer shell can effectively seal the connecting parts to prevent workers from being electrocuted during operation.

[0017] (ii) The tensile and compression resistant miniature threaded safety electrical connector achieves the effect of the connecting rod engaging with the connecting plate through its own elasticity when the socket is screwed into the insulating shell. At the same time, when the compression is excessive, the inner convex pressure rod can squeeze the outer shell outward to prevent the internal structure from being crushed and damaged, thus improving the service life.

[0018] (III) The tensile and compression resistant miniature threaded safety electrical connector has an inner spring plate on the side of the side fixing plate that is fitted inside the connecting thread rod. The inner spring plate can lock the connecting thread rod during rotation, achieving the effect of electrical locking. At the same time, the outer limiting ring and elastic pull rod can protect the connector when the external environment pulls on the connector.

[0019] (iv) The tensile and compression resistant miniature threaded safety electrical connector improves the device's pressure resistance when subjected to axial force by having the buckle plate counteract the side wiring when the electrical connector is subjected to axial tension.

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

[0027] like Figure 1-2As shown, this invention provides a technical solution: a tensile and compression-resistant miniature threaded safety electrical connector, comprising an insulating shell 5, an outer casing 3 fixedly connected to the outer surface of the insulating shell 5, a connecting device 4 sleeved on the bottom of the insulating shell 5, an adapter compression device 9 fixedly connected inside the opening on the surface of the insulating shell 5, a limiting ring plate 8 fixedly connected to the bottom of the outer casing 3, an outer ring plate 10 fixedly connected to the outer surface of the top of the insulating shell 5, a connecting rod 11 fixedly connected to the top of the adapter compression device 9, a connecting end 1 fixedly connected to the top of the connecting rod 11, and an electric threaded rod 7 fixedly connected to the outer surfaces between the opposite faces of the connecting rod 11. Through the setting of the electric threaded rod 7, when making an electric connection, the connecting device 4 can be directly rotated counterclockwise through the electric threaded rod 7 into the device, achieving a stable connection effect. Simultaneously, the insulating shell 5 and the outer casing 3 can effectively seal the connecting components, preventing electric shock to workers during operation.

[0028] This embodiment has the following working steps:

[0029] The connection threaded rod 7 allows the connecting device 4 to be directly rotated counterclockwise through the connection threaded rod 7 into the device during electrical connection, achieving a stable electrical connection effect. At the same time, the insulating shell 5 and the outer shell 3 can effectively seal the electrical connection components, preventing workers from being electrocuted during operation. Example

[0030] like Figure 3 As shown, based on Embodiment 1, the present invention provides a technical solution: the adapter extrusion device 9 includes a connecting rod 92, the bottom of which is fixedly connected to the outer surface of the insulating shell 5, both sides of the outer surface of the connecting rod 92 are fixedly connected to the inner wall of the opening on the surface of the insulating shell 5, the top of which is fixedly connected to the bottom of the connecting rod 11, and the connecting rod 92 has an internal groove 93, and an internal protruding pressure rod 94 and a locking plate 95 are fixedly connected inside the internal groove 93.

[0031] The inner convex pressure rod 94 penetrates the insulating shell 5 and extends to the outside, and the inner convex pressure rod 94 is pressed and adapted to the inner surface of the outer shell 3. The locking plate 95 is disposed in the inner cavity of the insulating shell 5, and the outer surface of the locking plate 95 has a side groove 96, the side of which is designed to connect a connecting spring piece 91. When the sleeve device 4 is screwed into the insulating shell 5, the connecting rod 92, through its own elasticity, cooperates with the locking plate 95 to achieve a close fit with the sleeve device 4. At the same time, when excessive pressure is applied, the inner convex pressure rod 94 can press the outer shell 3 outward to prevent internal structural damage and improve service life.

[0032] This second embodiment has the following working steps:

[0033] When the socket 4 is screwed into the insulating shell 5, the connecting rod 92 uses its own elasticity to engage with the connecting plate 95 to achieve a close fit with the socket 4. At the same time, when the pressure is excessive, the inner convex pressure rod 94 can push the outer shell 3 outward to prevent the internal structure from being crushed and to improve the service life. Example

[0034] like Figure 4-5 As shown, based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution: the sleeve device 4 includes a sleeve housing 41, an external collar 42 is fixedly connected to the outer surface of the sleeve housing 41, an elastic pull rod 43 is fixedly connected to the top of the external collar 42, and a limit ring 48 is fixedly connected to the top of the elastic pull rod 43.

[0035] An inner hook rod 44 is fitted into the recessed hole at the top of the sleeve housing 41. A side-mounted wiring 45 is fixedly connected to the bottom of the inner hook rod 44. A pressure-resistant device 49 is fixedly connected to the bottom of the side-mounted wiring 45. The pressure-resistant device 49 is fitted into the bottom of the sleeve housing 41. A side fixing plate 47 is fixedly connected between the opposite faces of the inner hook rod 44. An inner hanging spring plate 46 is fixedly connected to the inner surface of the side fixing plate 47. The inner hanging spring plate 46 on the side of the side fixing plate 47 is fitted into the connecting threaded rod 7. The inner hanging spring plate 46 can lock the connecting threaded rod 7 during rotation, achieving the effect of electrical locking. At the same time, the outer limiting ring 48 and the elastic pull rod 43 can protect the connector when the external environment pulls on the connector.

[0036] The pressure-resistant device 49 includes a power connector 494, the outer surface of which is fitted onto the bottom of the sleeve housing 41. An inner plate 493 is fixedly connected to the top of the outer surface of the power connector 494, and an elastic block 495 is fixedly connected to the surface of the inner plate 493.

[0037] A buckle plate 492 is fixedly connected to the top of the internal mounting plate 493, and the outer surface of the elastic block 495 is fixedly connected to the bottom end of the side wiring 45. The buckle plate 492 and the side wiring 45 are pressed and fitted together. When the electrical connector is subjected to axial tension, the buckle plate 492 can resist the side wiring 45, thereby improving the device's pressure resistance under axial force.

[0038] This embodiment three has the following working steps:

[0039] Step 1: The inner spring plate 46 on the side of the side fixing plate 47 is fitted inside the connecting threaded rod 7. The inner spring plate 46 can lock the connecting threaded rod 7 during rotation, achieving the effect of electrical locking. At the same time, the outer limiting ring 48 and the elastic pull rod 43 can protect the connector when the external environment pulls on the connector.

[0040] Step 2: When the electrical connector is subjected to axial tension, the buckle plate 492 can counteract the side wiring 45, thereby improving the device's pressure resistance when subjected to axial force.

[0041] The electrical connector provided in this embodiment achieves a stable electrical connection through a unique structural design, such as the threaded engagement between the connecting threaded rod and the socket device, effectively preventing loosening. The inner protruding pressure rod and locking plate in the compression device ensure a tight connection while effectively preventing damage to the internal structure due to compression, thus improving compression resistance. The insulating shell and outer casing fit tightly together, completely enclosing the electrical components, greatly enhancing safety performance and effectively preventing electric shock to personnel. Furthermore, the elastic pull rod and limiting ring in the socket device, as well as the buckle plate in the compression-resistant device, provide excellent buffering and pressure-bearing properties when the electrical connector is subjected to axial tension, further enhancing connection stability (emphasizing core advantages such as strong tensile strength, compression resistance, and safety performance). These innovative designs effectively solve the problems existing in traditional electrical connectors, providing reliable assurance for the stable operation of electronic equipment and electrical systems, and promoting the advancement of power component technology.
