[0004] Although the above technical solution completes the connection between the male end body and the female end body by pressing the pressing block to make the connecting block fit with the connecting rod, the staff needs to press the pressing block to complete the docking when the male end and the female end are docked, which increases the labor intensity of disassembly and assembly, and the pressing block is not provided with an anti-accidental touch structure. The pressing block may be subjected to external pressure, causing the connecting rod to separate from the connecting block, and then causing the male end to be disconnected from the female end, causing an accident. Therefore, we need to propose an arc-proof high-voltage interlocking connector. Utility Model Content

[0005] The purpose of the utility model is to provide an arc-proof high-voltage interlocking connector, which can be connected by just pressing the docking button during installation, with high installation efficiency. When disassembling, it is necessary to open the anti-accidental-touch structure, and then open the snap-on mechanism to achieve separation between the male end and the female end, improve the stability of the connection, avoid accidental touch separation, and improve the safety of the connection between the male end and the female end, so as to solve the problems raised in the above-mentioned background technology.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model mainly cooperates between the anti-mistouch component, the limit component, the locking plate, the movable reaming hole and the slot. When the male end body and the female end body need to be separated, the protective plate is first pushed to make the fixing pin slide in the movable reaming hole toward the male end body, thereby making the card strip on the locking strip disengage from the slot on the locking plate, and then the protective plate is flipped over to separate the locking strip from the locking plate, so as to facilitate the separation of the male end body and the female end body. Under the buckling action of the two sets of locking plates and the locking strip, the connection between the male end body and the female end body is stable, thereby improving the stability of the current connection.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5The utility model provides a technical solution: an arc-proof high-voltage interlocking connector, comprising a male end body 1 and a female end body 2, two sets of locking plates 5 are fixedly connected to the upper surface of the male end body 1, a limiting frame 8 is integrally formed on the upper surface of the female end body 2, a limiting component 10 is fixedly connected to one side of the inner side of the limiting frame 8, and an anti-mistaken touch component 9 is hinged on the outer side of the limiting frame 8;

[0025] The anti-accidental touch assembly 9 includes a protective plate 91, and side plates 92 are fixedly connected to both sides of the protective plate 91. The opposite sides of the two sets of side plates 92 are plugged with fixing pins 94. Both sides of the limit frame 8 are provided with movable hinge holes 11 for sliding connection of the fixing pins 94. The lower surface of the protective plate 91 is fixedly connected with two sets of locking strips 96 and two sets of double-plate connecting seats 98.

[0026] The limiting assembly 10 includes a fixing plate 101 fixedly connected to one side of the limiting frame 8, two sets of mounting grooves 102 are opened at one end of the upper surface of the fixing plate 101, and telescopic rods 103 are hinged inside the two sets of mounting grooves 102, the upper end of the telescopic rod 103 is hinged to the double-plate connecting seat 98, and the outer side of the telescopic rod 103 is sleeved with a tension spring 105, and the two ends of the tension spring 105 are respectively fixed to the lower end of the double-plate connecting seat 98 and the upper surface of the fixed block.

[0027] Two sets of protrusions 104 are symmetrically welded at both ends of the telescopic rod 103 , and both ends of the telescopic rod 103 are respectively hinged to the double-plate connecting seat 98 and the mounting groove 102 through the protrusions 104 .

[0028] One side of the two sets of locking strips 96 is integrally formed with a clamping strip 97, and one side of the two sets of locking plates 5 is provided with a clamping slot 6 for the clamping strip 97 to be inserted into. The clamping strip 97 fits with the clamping slot 6 to facilitate the position limitation of the protective plate 91, thereby preventing the locking plate 5 from separating from the locking strip 96.

[0029] The cross-section of the clamping strip 97 is set in a quarter circle, and the upper end of the other side of the locking plate 5 is set in a circular chamfer. The contact ends of the clamping strip 97 and the locking plate 5 are both set in an arc shape, which reduces the friction of the conflict and facilitates the docking of the male end body 1 and the female end body 2.

[0030] The cross-section of the movable reaming hole 11 is T-shaped, and the width of the movable reaming hole 11 is greater than the outer diameter of the fixing pin 94. The movable reaming hole 11 facilitates the sliding movement of the fixing pin 94, thereby facilitating the flipping of the protective plate 91. If the protective plate 91 is not pushed, the protective plate 91 is limited by the clamping strip 97 and cannot be opened, thereby avoiding accidental touch that causes the male end body 1 and the female end body 2 to separate.

[0031] The outer side of the male end body 1 is integrally formed with multiple groups of reinforcing ribs 3, and the four sides of the female end body 2 are integrally formed with docking parts 7 for the multiple groups of reinforcing ribs 3 to be plugged in. Two groups of limiting ribs 4 are arranged on the upper surface of the male end body 1, and the opposite sides of the two groups of limiting ribs 4 are respectively in conflict with the other two sides inside the limiting frame 8. Two groups of locking plates 5 are arranged on the opposite sides of the two groups of limiting ribs 4. Through the reinforcing ribs 3 and the docking part 7, the stability of the docking between the male end body 1 and the female end body 2 is improved, thereby improving the stability of the connection and ensuring the stability of the flow of current.

[0032] A first anti-slip groove 93 is provided at one end of the upper surface of the protective plate 91, and a second anti-slip groove 95 is provided on the opposite side of the two sets of side plates 92. The first anti-slip groove 93 facilitates pushing the protective plate 91 to separate the card strip 97 from the card slot 6. The second anti-slip groove 95 increases the friction when flipping the protective plate 91, thereby preventing the protective plate 91 from slipping and making it difficult to flip over.

[0033] When in use, the male end body 1 is directly inserted into the female end body 2, and then the two groups of limiting ribs 4 are inserted into the limiting frame 8, the circular chamfers on the two groups of locking plates 5 conflict with the locking strips 96 on the lower surface of the protective plate 91, and then the protective plate 91 is flipped around the fixing pin 94 as the axis, so that the two groups of locking plates 5 conflict with the two groups of locking strips 96 respectively, and under the elastic action of the tension spring 105, the lower surface of the protective plate 91 conflicts with the upper surface of the limiting rib 4, and then the card groove 6 on the locking plate 5 is matched with the card strip 97 on the locking strip 96, so as to avoid the male end body 1 and the female end body 2 from being disconnected during use, thereby improving the stability after docking. And to prevent accidental touch from causing the male end body 1 to separate from the female end body 2, when the male end body 1 is separated from the female end body 2, the first anti-slip pattern 93 is used to push the protective plate 91 close to the male end body 1, so that the fixing pin 94 on the side plate 92 slides a certain distance in the movable hinge hole 11, so that the card strip 97 on the locking strip 96 is separated from the card slot 6 on the locking plate 5, and the protective plate 91 is flipped up through the second protective pattern on the two side plates 92, so that the protective plate 91 is flipped over with the fixing pin 94 as the axis, so that the locking strip 96 is higher than the locking plate 5, and then the male end body 1 is pulled out of the female end body 2, which is convenient for disassembly and improves the convenience of maintenance.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
