Description

Technical Field

[0001] The utility model belongs to the technical field of anti-misinsertion equipment for electrical connectors, and particularly relates to an anti-misinsertion device for electrical connectors. Background Art

[0002] Energy storage connectors are usually used for high current connections and can be applied in a variety of connector fields, such as military industry, aviation, urban rail transit, new energy vehicle charging stations, large-scale electrical equipment, and automated control systems. When energy storage is introduced into the power production system, demand management can be effectively performed, peaks can be cut and valleys can be leveled, and loads can be smoothed. Power equipment can be used more effectively, power supply costs can be reduced, and the application of renewable energy can be promoted. It is also a means to improve the stability of power system operation and adjust the frequency. In the process of using existing energy storage connectors, when children insert metal objects into the energy storage connectors, they are prone to electric shock. In addition, when the existing energy storage connectors collide during use, the connection between the energy storage connectors is easily loosened, and in severe cases, they may fall off.

[0003] For example, a utility model with a publication number of CN218732089U discloses a novel energy storage connector. The technical solution of this patent includes a plug connector and a socket. The plug connector includes a plug connector front shell, a plug connector rear shell and a plug connector lower shell. The plug connector front shell and the plug connector rear shell are threadedly connected to form a cavity structure with openings at both ends and a hollow interior. A plug connector conductor, a cable connector, a plug and a clamping claw are arranged in the cavity. An installation groove is provided on the plug connector front shell, and a locking device is installed in the installation groove. The plug connector lower shell cover is arranged at the installation groove. The socket includes a socket shell and a socket conductor. The socket conductor is arranged through the socket shell. The socket shell extends outward near one end of the plug connector to form a circular convex edge. The circular convex edge is limitedly connected to the locking device. The device does not have an anti-error mechanism during use, and the mechanism is prone to loosening or even falling off during collision. Therefore, an anti-misinsertion device for an energy storage connector is proposed. Utility Model Content

[0004] In view of this, the utility model aims to provide an anti-misinsertion device for electrical connectors to address the deficiencies of the prior art. The device can not only achieve a better connection, but also prevent children from misinserting the connector when not in use, thereby causing electric shock. The device can also be connected quickly and prevent power outages during collisions.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an anti-misinsertion device for an electrical connector, comprising a base, a plurality of circular holes are respectively arranged at the four corners of the right end of the base, two support rods are arranged on the front side of the right end of the base, the inner ends of the two support rods are respectively provided with rotating shafts, the ends of the inner ends of the two rotating shafts are jointly provided with a cover plate, a worm gear is arranged on the top of the top rotating shaft, two support plates are arranged on the top of the top support rod, a worm meshing with the worm gear is jointly arranged in the middle of the two support plates, a rotating motor connected to the worm gear is arranged on the front side of the front support plate, and clamping mechanisms are respectively arranged at the upper and lower ends of the base.

[0006] As a further improvement of the present invention, the clamping mechanism includes fixed blocks respectively arranged at the upper and lower ends of the base, the middle parts of the two fixed blocks are respectively provided with through holes, the middle parts of the two fixed blocks are also provided with square holes intersecting with the through holes, the outer ends of the two fixed blocks are respectively provided with circular grooves connected with the square holes, the bottoms of the two square holes close to the base are respectively provided with multiple springs, the multiple springs are welded to the fixed blocks, slides are respectively slidably arranged inside the two square holes, clamping holes are respectively provided in the middle parts of the two slides, cylinders connected with the slides are respectively provided at the outer ends of the two slides, the cylinders and the slides are welded, and pressure heads are respectively provided at the outer ends of the two cylinders.

[0007] As a further improvement of the utility model, a plug is provided at the right end of the base, a connecting plate is provided at the right end of the plug, four connecting columns corresponding to the round holes are provided on the left side of the connecting plate, card joints corresponding to the through holes are provided at the upper and lower ends of the connecting plate, a card plate is provided on the right side of the connecting plate, a handle is provided on the right side of the card plate, a plurality of arc grooves are provided on the handle, an electric wire is provided at the bottom of the handle, a fixing plate is provided at the left end of the base, connecting holes are respectively provided at the four corners on the fixing plate, and a copper piece is provided on the left side of the fixing plate.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] First, start the rotating motor. The rotation of the rotating motor drives the worm to rotate, and the worm drives the worm wheel meshing with it to rotate, which in turn drives the rotating shaft to rotate, and then causes the cover to rotate. Therefore, when the base is not in use, the cover will cover the base to prevent misinsertion.

[0010] Secondly, when the plug needs to be plugged into the base, the card connector needs to be aligned with the through hole, and then the plug and the base need to be forced to match the circular hole with the connecting column, so that the connection between the two is successful and will not be disconnected due to external force collision.

[0011] Thirdly, when the base and the plug need to be separated, a manual pressing head is required. The pressing of the pressing head causes the cylinder to push the slide plate to move, thereby compressing the spring, so that the card hole on the lower slide plate corresponds to the through hole on the fixed block, thereby removing the card joint and separating the base and the plug.

[0012] Fourthly, the arc groove provided on the handle makes it convenient for users to manually hold the device and prevent the device from slipping. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to better understand the present invention, the content of the present invention is further clearly described below in conjunction with the embodiments, but the protection content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0020] like Figure 1 , 3As shown, an anti-misinsertion device for an electrical connector includes a base 101, a plurality of circular holes 102 are respectively arranged at the four corners of the right end of the base 101, two support rods 103 are arranged on the front side of the right end of the base 101, the inner ends of the two support rods 103 are respectively provided with rotating shafts 104, the ends of the inner ends of the two rotating shafts 104 are jointly provided with a cover plate 105, a worm gear 106 is arranged on the top of the top rotating shaft 104, two support plates 107 are arranged on the top of the top support rod 103, a worm 108 meshing with the worm gear 106 is jointly arranged in the middle of the two support plates 107, a rotating motor 109 connected to the worm 108 is arranged on the front side of the front support plate 107, and a clamping mechanism is respectively arranged at the upper and lower ends of the base 101.

[0021] like Figure 1 , 2 As shown in , 4, the clamping mechanism includes fixed blocks 110 respectively arranged at the upper and lower ends of the base 101, through holes 111 are respectively arranged in the middle of the two fixed blocks 110, and square holes 112 intersecting the through holes 111 are also arranged in the middle of the two fixed blocks 110, and circular grooves 113 connected with the square holes 112 are respectively arranged at the outer ends of the two fixed blocks 110, and a plurality of springs 114 are respectively arranged at the bottom of the two square holes 112 close to the base 101, and the plurality of springs 114 are welded to the fixed blocks 110, and slide plates 115 are respectively slidably arranged inside the two square holes 112, and clamping holes 116 are respectively arranged in the middle of the two slide plates 115, and cylinders 117 connected with the slide plates 115 are respectively arranged at the outer ends of the two slide plates 115, and the cylinders 117 and the slide plates 115 are welded, and pressure heads 118 are respectively arranged at the outer ends of the two cylinders 117.

[0022] like Figure 1 As shown, a plug 119 is provided at the right end of the base 101, a connecting plate 120 is provided at the right end of the plug 119, four connecting columns corresponding to the round holes 102 are provided on the left side of the connecting plate 120, and card connectors 201 corresponding to the through holes 111 are provided at the upper and lower ends of the connecting plate 120, a card plate 202 is provided on the right side of the connecting plate 120, a handle 203 is provided on the right side of the card plate 202, a plurality of arc grooves 204 are provided on the handle 203, and an electric wire 205 is provided at the bottom of the handle 203, a fixing plate 206 is provided at the left end of the base 101, connecting holes are respectively provided at the four corners on the fixing plate 206, and a copper piece 207 is provided on the left side of the fixing plate 206.
