Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to a connection component with a grounding structure. Background Technology

[0002] In existing connector technologies, such as sockets, grounding is essential. When electrical equipment leaks current, especially when the equipment has a metal casing, both the socket and the equipment casing become live. If a person touches the equipment directly, the current will flow through the person and be conducted to the ground, causing harm. By grounding the wire, the current flows into the ground through the wire, thus preventing electric shock and protecting personal safety.

[0003] In industrial operations, where space is large and equipment sometimes needs to be moved, grounding is inconvenient. If the connector itself can be directly grounded, it would ensure both safety and ease of use of the equipment. Therefore, it is necessary to design a connection component with a grounding structure. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a connection component with a grounding structure to solve the problem of lacking a ground wire in special circumstances.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0035] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0037] In one embodiment, refer to the accompanying drawings. Figures 1 to 8 The figure shows a connection assembly with a grounding structure, including a female connector 10 and a male connector 20 that matches the female connector. The female connector 10 includes a female connector housing 11 with protrusions (not marked) on both sides and screw holes (111). Screws 12 pass through the screw holes to connect and fix the female connector 10 and the male connector 20.

[0038] The female housing 11 includes an extended cable clamp 13, a waterproof gasket 14 inside the cable clamp, and an outer cover 15 adapted to the cable clamp. The connection hole 133 of the cable clamp extends into the interior of the female housing. The outer surface of the cable clamp 13 is provided with an external thread 131. Adjacent to the external thread are several claws 132 forming a circumference. The claws are made of elastic material and there is a gap between the claws.

[0039] The waterproof pad 14 consists of a threaded part 141, a column 142 and a central hole 143. The threaded part 141 is located to the left of the column 142 and has fewer turns than the external thread 131 of the cable clamp to increase the friction between the claw 132 and the waterproof pad 14. The column 142 matches the connecting hole 133. The column has a central hole 143 and a crack (not marked) on the side of the side to facilitate the placement of the cable.

[0040] The outer cover 15 consists of an internal thread 151, vertical grooves 152, and a wire hole 153. The internal thread 151 is compatible with the external thread 131. Several vertical grooves 152 are evenly arranged around the outer surface of the outer cover 15 to facilitate friction when screwed onto the cable clamp 13. The wire hole 153 can hold the cable, the waterproof pad 14, and the cable clamp 13. When the outer cover 15 is screwed onto the cable clamp 13, the claw 132 retracts and tightly grips the waterproof pad 14 and the cable in the connection hole 133, reducing the gap between the cable and the waterproof pad 14 to achieve a waterproof effect.

[0041] The female connector housing 11 is equipped with a female connector waterproof ring 16, a plug core n, a grounding terminal 17, a switch terminal 18, and a brake terminal m. The grounding terminal 17, the switch terminal 18, and the brake terminal m are inserted into the corresponding grooves of the plug core n, and then placed into the corresponding positions inside the female connector housing 11. The female connector waterproof ring 16 is placed inside the female connector housing 11 and is adjacent to the plug core n inside the housing.

[0042] The male connector 20 housing 21 is equipped with a grounding terminal (pin) 25, a power terminal (pin) group 26, and a brake terminal (pin) 27. The grounding terminal (pin) 25 is injection molded into the male connector housing 21 and fixed by inserting a pin (not marked) through the pin hole 213. After molding, the grounding terminal (pin) 25 is divided into a plug part 251, a connecting part 252, and a ring part 253.

[0043] The plug portion 251 has a "T-shaped" structure and a truncated bevel at the bottom for insertion into the grounding terminal 17 of the female connector. It also includes two limiting arms 2511 that hold the grounding terminal (pin) 25 inside the male connector housing. The connecting portion 252, located between the two limiting arms 2511, has a "Z-shaped" structure and extends with a slanted arm 2521 attached to the surface of the male connector housing 21. The connecting portion connects the plug portion 251 and the grounding ring 253, which is located on one of the four corner screw holes 211 in the male connector housing 21. The four corner screws 23 pass through the four corner screw holes 211 and then through the hole b of the grounding ring 253, placing them on the back of the mating surface a. The hole b is the same size as the four corner screw holes 211. After the female connector 10 and the male connector 20 are matched and connected, the grounding terminal 17 of the female connector 10 is connected and connected to the grounding terminal (pin) 25 of the male connector. The nut of the four corner screws 23 contacts the grounding terminal (pin) 25, and the screws lock with the male connector housing 21 to achieve grounding.

[0044] The power terminal (pin) group 26 consists of three identical power terminals (pins) arranged at equal intervals. The power terminal (pin) plug portion 261 and the grounding terminal (pin) plug portion 251 are both "T-shaped" structures, and the lower part of the plug portion is a truncated pyramid to facilitate connection to the switch terminal 18 of the female socket. The connecting shaft 262 is "arc-shaped" to connect the plug portion 261 and the "U-shaped" transmission portion 263. The male housing 21 has a slot 215 for a pair of brake terminals (pins) 27 to be fitted and a fixing slot 214 for the power terminal (pin) group plug portion 261 to pass through. The fixing slot has a narrow slot (not marked). When assembling the power terminals (pins), the plug portion 261 passes through the fixing slot 214. When the locking arms 2611 are located on both sides of the plug portion 261 and are locked into the narrow slot (not marked) of the fixing slot, the connecting shaft 262 and the transmission portion 263 are located above the wide slot (not marked) of the fixing slot with a certain curvature.

[0045] Two brake terminals (pins) 27 are inserted into corresponding slots 215 and then connected to corresponding brake terminals m. The structure of brake terminals (pins) 27 is similar to that of power terminals (pins), both consisting of a "T-shaped insertion part," an "arc-shaped connection part," and a "U-shaped transmission part." The "T-shaped insertion part" of brake terminals (pins) 27 is narrower in width than insertion part 261, and the corresponding truncated pyramid below the "insertion part" is smaller. Grounding terminals (pins) 25 and power terminals (pins) 26 are arranged vertically in one row, while brake terminals (pins) 27 are arranged in another row.

[0046] The male connector housing 21 has four equally sized corner screw holes 211 at its four corners, and corner screws 23 that fit into the corner screw holes to fix the male connector 20 to other equipment, allowing the equipment to be placed on the ground. There are through holes (not marked) between the four corner screw holes 211 on both the left and right sides, each for a nut 22. The outer side of the nut has a serrated stop 222 to position the nut within the through hole. The nut has internal threads 221 that match the screw 12. For ease of installation, the thickness of the male connector housing has been reduced by 0.2 mm from the original 3.45 mm. The round protrusion 223 of the nut protrudes from the male connector housing 21 and fits into the screw hole 111 of the female connector housing.

[0047] The male connector housing 21 has a groove 212 that fits the male connector waterproof ring 24 so that the waterproof ring 24 surrounds the grounding terminal (pin) 25, the power terminal (pin) group 26 and the brake terminal (pin) 27.

[0048] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0049] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
