Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connections, and in particular to a high-voltage socket module with integrated protection. Background Technology
[0002] High-voltage socket modules are widely used in power systems, industrial equipment, and new energy fields (such as electric vehicle charging sockets and battery swapping connectors). The high-voltage socket and high-voltage terminals are coupled to achieve the function of a high-voltage connector. To ensure the reliability and safety of the high-voltage socket module, it typically has IPXXB anti-finger contact protection before coupling. However, this protection has a drawback: in harsh operating environments where high-voltage socket modules are surrounded by dust, particulate matter, or other hard contaminants, these contaminants can easily penetrate the interior of the high-voltage socket, potentially leading to poor electrical contact, short circuits, poor insulation, and even burning, thus reducing product reliability and increasing maintenance costs.

The anti-touch finger cap is axially slidably connected to the insulating shaft. The end sealing ring is fixedly sleeved on the outer peripheral wall of the anti-touch finger cap. The sealing ring is fixedly sleeved on the outer peripheral wall of the end sealing ring and elastically fits the insertion hole. The damping spring is sleeved on the outside of the insulating shaft and its two ends fit the inner end wall of the insertion hole and the inner wall of the anti-touch finger cap. Under the elastic force of the damping spring, the anti-touch finger cap slides outward to fit the lower end face of the stop shoulder and the end sealing ring and sealing ring connected thereto seal the outer port of the insertion hole.
[0008] When the high-voltage socket module and the pin module are coupled, the damping spring is compressed and the integrated protection part slides to the inner end of the socket; when the two are decoupled, the elastic restoring force of the damping spring causes the integrated protection part to return to the outer port of the socket to seal.

[0010] In some implementations, the upper positioning shoulder is a chamfered groove surface, and the stop shoulder is an inverted frustum.
[0011] In some embodiments, the lower end of the cap body is also provided with a cylindrical internal storage groove.
[0012] In some embodiments, the cap body is provided with at least one axially penetrating elastic opening; the lower end face of the cap body is provided with an angled guide surface, and the upper end of the damping spring is sleeved on the guide surface.
[0013] In some embodiments, an insulating cap is fixedly connected to the outer end of the insulating shaft, and the insulating cap fits against the upper end face of the connecting stop shoulder. In its natural state, it can slide into the outer receiving groove.
[0014] In some embodiments, the front end of the socket body is further provided with an annular mounting groove, and a torsion spring is interference-fitted into the mounting groove, and the torsion spring is interference-fitted into the pin.
[0015] In some implementations, the internal threaded hole at the center of the inner wall of the socket body is connected to the stud end of the insulating shaft;
[0016] The positioning shoulder at the upper end of the stud fits against the inner wall of the connecting socket.
[0017] In some embodiments, an inner sealing groove is provided in the middle of the outer peripheral wall of the end seal ring to fit an interference fit sealing ring.
[0018] In some implementations, the damping spring is a tower spring;
[0019] The anti-touch finger cap, end sealing ring, and insulating cap are made of elastic insulating material;
[0020] Alternatively, the socket body may be made of copper, and the insulating shaft may be made of plastic.
[0021] The beneficial effects of this integrated protective high-voltage socket module are as follows: First, it integrates dustproof and finger-proof functions, providing high safety protection performance and improving the protection level of the socket module, effectively achieving single-end dustproofing of the socket cavity; Second, the high protection level prevents dust, particulate matter, or other hard contaminants from easily intruding into the interior of the high-voltage socket, effectively protecting electrical contact parts such as rotating springs, ring springs, and torsion springs inside the socket cavity, improving the stability of electrical contact, enhancing product reliability, reducing product cleaning and maintenance costs, and extending product lifespan; Third, the integrated protective components reduce the number of parts, lowering the cost of parts and reducing the cost of product use and maintenance.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, while the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.
[0033] Figures 1 to 6 A schematic diagram illustrates an integrated protective high-voltage socket module according to one embodiment of the present invention. As shown in the figure, the integrated protective high-voltage socket module includes: a socket body 1, an insulating shaft 2, and an integrated protective part 00;
[0034] One end of the socket body 1 is provided with an axial insertion hole 10, which is usually a blind hole structure; preferably, the front end of the socket body 1 is also provided with an annular mounting groove 11, and a torsion spring 8 is interference-fitted in the mounting groove 11, and the torsion spring 8 is interference-fitted in the pin module 02.
[0035] The insulating shaft 2 is coaxially disposed inside the insertion hole 10 and its inner end is threaded to the inner end wall of the insertion hole 10. The outer end of the insulating shaft 2 is provided with a stop shoulder 21.
[0036] The integrated protective unit 00 includes a finger cap 3, an end sealing ring 4, a sealing ring 5, and a damping spring 6.
[0037] The anti-touch finger cap 3 is axially slidably connected to the insulating shaft 2.
[0038] End sealing ring 4 is fixedly connected to the outer peripheral wall of anti-touch finger cap 3.
[0039] The sealing ring 5 is fixedly sleeved on the outer peripheral wall of the end sealing ring 4 and elastically fits the insertion hole 10. In a preferred fixing structure, the outer peripheral wall of the end sealing ring 4 is provided with an inner sealing groove 41, and the sealing ring 5 is radially elastically interference-fitted into the inner sealing groove 41. The sealing ring 5 is preferably an O-ring rubber ring, which can effectively seal the insertion hole without gaps.
[0040] The damping spring 6 is sleeved outside the insulating shaft 2, with both ends fitting against the inner end wall of the insertion hole 10 and the inner wall of the anti-touch finger cap 3. Under the elastic force of the damping spring 6, the anti-touch finger cap 3 slides outward to fit against the lower end face of the connecting stop shoulder 21 and the end sealing ring 4 and sealing ring 5 connected thereto, sealing the outer port of the insertion hole 10. The damping spring 6 is preferably a tower spring, which can achieve good elastic recovery and has a stable structure, avoiding the shaking, skewing and jamming of the integrated protective part 00.
[0041] When the high-voltage socket module 01 and the pin module 02 are coupled, the damping spring 6 is compressed and the anti-touch finger cap 3, end sealing ring 4 and sealing ring 5 of the integrated protection part 00 slide to the inner end of the socket 10; when the two are decoupled, the elastic restoring force of the damping spring 6 causes the anti-touch finger cap 3, end sealing ring 4 and sealing ring 5 of the integrated protection part 00 to return to the outer port of the sealing socket 10.
[0042] This integrated protection high-voltage socket module has an integrated protection part 00. Before coupling, the integrated protection part 00 seals the socket 10. When coupling, the pin module 02 pushes the integrated protection part 00, the damping spring 6 is compressed, the integrated protection part 00 slides axially to the inner end, and the coupling connection is released. Under the action of the damping spring 6, the integrated protection part 00 automatically resets. The integrated protection part 00 achieves dustproof and IPXXB anti-finger-touch functions before coupling. The integrated protection unit 00 achieves complete sealing of the plug hole 10 through the anti-touch finger cap 3, end sealing ring 4, and sealing ring 5. Dust, solid particles, and other contaminants are blocked from the outside of the plug hole, protecting the electrical contact components (such as torsion spring 20) inside the plug hole. This reduces the risk of internal parts being scratched by hard particles during insertion and removal, improves the stability and reliability of electrical contact, and reduces the use and maintenance costs of the product. The anti-touch finger cap 3 is installed at the front end of the insulating shaft 2 to prevent spherical objects (such as fingers) from touching live parts and causing danger. The anti-touch finger reaches level B (that is, when the equipment is tilted at 15°, it can prevent spherical objects (such as fingers) with a diameter greater than 12.5mm from touching live parts inside the shell or parts that may cause danger due to movement).
[0043] The beneficial effects of this integrated protective high-voltage socket module are as follows: First, it integrates dustproof and finger-proof functions, providing high safety protection performance and improving the protection level of the socket module, effectively achieving single-end dustproofing of the socket cavity; Second, the high protection level prevents dust, particulate matter, or other hard contaminants from easily intruding into the interior of the high-voltage socket, effectively protecting electrical contact parts such as rotating springs, ring springs, and torsion springs inside the socket cavity, improving the stability of electrical contact, enhancing product reliability, reducing product cleaning and maintenance costs, and extending product lifespan; Third, the integrated protective components reduce the number of parts, lowering part costs and reducing product usage and maintenance costs.
[0044] Furthermore, the anti-touch cap 3 includes a circular cap body 30, with an axial slide 31 slidably connected to the middle section of the insulating shaft 2. The upper positioning shoulder 32 of the cap body 30 can fit against the stop shoulder 21, and the cylindrical outer receiving groove 33 at the upper end of the cap body 30 passes through the stop shoulder 21 with a small gap. Preferably, the upper positioning shoulder 32 is a chamfered groove surface in the shape of an inverted frustum, and the stop shoulder 21 is an inverted frustum. Its beneficial effect is that this arrangement can achieve a good contact sealing position.
[0045] Preferably, the lower end of the cap body 30 is also provided with a cylindrical internal storage groove 34, and the upper end of the damping spring 6 is located in the internal storage groove 34 or the positioning shoulder 23 of the insulating shaft 2 can enter the internal storage groove 34. The beneficial effect is that this setting can reduce the size of the parts.
[0046] Preferably, the cap body 30 is provided with at least one axially penetrating elastic opening slit 35; its advantage is that this arrangement can achieve good elastic clamping and separation.
[0047] Preferably, the lower end face of the cap body 30 is provided with an angled guide surface 36, and the upper end of the damping spring 6 is sleeved on the guide surface 36.
[0048] Furthermore, the outer end 20 of the insulating shaft 2 is fixedly connected to the insulating cap 7, which fits against the upper surface of the connecting stop shoulder 21. In its natural state, it can slide into the outer receiving groove 33. Preferably, the outer end 20 includes a cylindrical outer locking platform 201 and an annular groove-shaped inner locking groove 202 arranged sequentially. The inner locking groove of the insulating cap 7 elastically fits onto the outer locking platform 201, and its annular outer buckle 71 connects to the inner locking groove 202. Its beneficial effect is that this arrangement can achieve a better anti-finger-touch function.
[0049] Furthermore, the inner wall of the insertion body 1 has an internally threaded hole 12 with an axial blind hole structure at its center, and the internally threaded hole 12 is connected to the stud end 22 of the insulating shaft 2; the upper end of the stud end 22 is provided with a positioning shoulder 23, which fits against the inner end wall of the insertion body 1. The beneficial effect is that this setting facilitates assembly and disassembly.
[0050] Furthermore, the other end of the socket body 1 is provided with a rectangular anti-rotation surface and the center of the end face is provided with an external thread blind hole 15 for connecting the aluminum bar;
[0051] The insertion body 1 is also provided with several external sealing grooves 13 and radial through holes 14 that are respectively connected to the external thread blind hole 15 and the insertion hole 10. The external sealing grooves 13 are used to place sealing elements, and the radial through holes 14 are used to install temperature detection elements.
[0052] Preferably, the finger-proof cap 3, end sealing ring 4, and insulating cap 7 are made of elastic insulating material. The beneficial effect is that this design achieves excellent finger-proof functionality.
[0053] Preferably, the socket body 1 is made of copper, and the insulating shaft 2 is made of plastic. The advantages are that copper has good electrical conductivity, thermal conductivity, ductility, and corrosion resistance.
