Description

Technical Field

[0001] The utility model relates to the technical field of plug devices, in particular to a protective cover plate and a plug assembly. Background Art

[0002] With the rapid development of the energy storage industry, industry customers have increasingly higher requirements for the quality stability, protection performance, cost and wiring efficiency of energy storage connectors.

[0003] The existing traditional energy storage connector plugs are mostly rubber-coated plug sleeves, crimped cables, and matched with seals and nuts to achieve the IP67 protection requirements of the cable end and IP20 protection requirements of the plug-in. This solution has more plug parts and higher cable costs. In order to reduce costs and improve wiring efficiency, the copper busbar quick plug solution came into being. However, although the copper busbar quick plug meets the IP67 protection requirements of the cable end, the IP20 protection requirements of the plug-in port are not well solved. Generally, a hinged cover or a separate disposable cover is used to achieve IP20 protection. The former has a complex mold and an unstable hinge structure, and the latter cover is easy to lose and needs to be improved. Utility Model Content

[0004] In order to solve at least one of the above technical defects, the utility model provides the following technical solutions:

[0005] The first aspect of the present application document discloses a protective cover plate, which is connected to a plug socket to form a protection. The cover plate has a positioning column on the plate body that is plugged and fixed with a slot at the plug socket. The cover plate has protruding support blocks on both sides of the top surface of the plate body, and the support blocks are used to support the snap-on parts at the plug socket.

[0006] In this solution, a cover plate structure is designed. The cover plate is fixed at the socket of the plug through a positioning column. The cover plate blocks the socket to form a protection, and a support block is designed. When the cover plate is inserted into the socket, the support block abuts against the fastener to form a support. When the cover plate is installed on the plug, it can effectively provide protection for the internal components of the socket. The support block supports the fastener to form a protection to prevent the fastener from being significantly deformed due to impact.

[0007] Furthermore, the positioning column protrudes outwardly from the side surface of the plate body and its bottom end passes over the bottom surface of the plate body. The bottom end of the positioning column passes over the bottom surface of the plate body to facilitate the mating with the socket.

[0008] Furthermore, the positioning posts are located at the front and rear sides, and the support blocks are located at the left and right positions of the top surface. The overall distribution is a cross configuration, and the reasonable layout is convenient for docking with the plug socket.

[0009] Furthermore, the support blocks all incline outwards and the ends of the support blocks protrude from the side surface of the plate body. During the docking process between the support blocks and the plug sockets, the outer side surfaces of the support blocks abut against the fasteners at the sockets and cause them to rotate outwards, facilitating installation.

[0010] Furthermore, reinforcing ribs are arranged between the inner side surfaces of the support blocks and the corresponding top surfaces of the plate bodies to improve the structural strength.

[0011] The second aspect of this application document discloses a plug assembly, including a plug and the above-mentioned cover plate. Fasteners are arranged on the opposite side surfaces of the upper sockets of the plug. The leading ends of the fasteners extend above the sockets. Slots for plugging and cooperating with positioning columns are arranged at the socket walls of the plug. When the positioning columns at the cover plate are plugged into the slots at the sockets, the support blocks are located between the leading ends of the two fasteners.

[0012] The cover plate is fixedly connected by plugging the positioning columns into the slots at the sockets. The cover plate seals the sockets to improve the protection ability. Slots are formed at the socket walls, such as the peripheral walls of the sockets, facilitating docking with the positioning columns and avoiding a great impact on the structure of the plug.

[0013] When the cover plate is installed on the plug socket, the support blocks are located between the leading ends of the two fasteners. When the fasteners are rotated towards the support blocks under the influence of external forces, the support blocks abut against the fasteners to form a support, which helps to limit the rotation range of the fasteners, thereby extending the service life.

[0014] Furthermore, slots for plugging and cooperating with positioning columns for fixing are also arranged at the end of the plug opposite to the position of the socket. When the plug is in use, the cover plate needs to be removed, and then it can be directly plugged and fixed at the end of the plug opposite to the socket, without structures such as hinges, avoiding loss.

[0015] Furthermore, ribs are arranged on the side surfaces of the plug. Slots are formed between adjacent ribs on the side surfaces of the socket and on the side surface of the end of the plug opposite to the socket. Strengthening the structural strength of the plug side with ribs is a conventional design. The size of the positioning columns can be predetermined to meet the plugging into the gap between adjacent ribs, reducing the impact on the structure of the plug.

[0016] Furthermore, the support blocks abut against the leading ends of the fasteners to form a support, further limiting the rotation range of the fasteners.

[0017] Furthermore, the fastener includes a wrench part, a hook part and a connecting part. The wrench part is connected to the hook part. The connecting part is arranged at the connection or near the connection between the wrench part and the hook part. The connecting part is connected to the side surface of the socket. The end of the hook part is above the socket.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] 1. The present utility model designs a cover plate to better dock with the plug, improve the protection performance of the internal components of the plug, better support the buckle member, and help extend its service life.

[0020] 2. In this plug assembly, the position of the cover plate can be adjusted without structures such as hinges, reducing the phenomenon of the cover plate being lost. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following further illustrates the present utility model in conjunction with the drawings and specific embodiments.

[0030] Embodiment 1

[0031] In this example, a plug assembly includes a plug and a cover plate. As Figure 3 shown, the cover plate 2 is placed at the socket 14 of the plug 1 to block the socket to form protection, reduce the entry of sundries, and also avoid the internal components in the plug cavity from being damaged by impact. In addition, as Figure 4 shown, when the plug 1 is in use, the cover plate 2 can also be detached from the socket 14 and placed at the end of the plug opposite to the position where the socket is located to avoid loss.

[0032] In this example, the cover plate structure is as follows Figure 1 , Figure 2 As shown, the plate body 21 of the cover plate 2 is provided with a positioning post 22, which is integrally formed at the opposite side of the plate body 21 and protrudes outward from the opposite side, so that the positioning post is plugged into the slot at the socket. Figure 3 As shown, a groove is formed on the side opposite to the socket 14 of the plug 1, namely, the slot 13, and the slot 13 faces upward. When in use, after the positioning column of the cover plate corresponds to the slot of the slot, the cover plate is pressed down to insert the positioning column into the slot and fix it by interference fit, and the plate body of the cover plate 2 blocks part of the socket or blocks all the sockets. For the convenience of plugging, the bottom end of the positioning column 22 in this example passes over the bottom surface of the plate body 21, which is convenient for limiting the size of the plate body, such as the length and width of the plate body is slightly larger than the length and width of the socket. After the positioning column is plugged into the slot, the plate body covers the socket to block it. The shape of the plate body can be rectangular, circular, etc.

[0033] In this example, the cover plate 2 has protruding blocks on both sides of the top surface, namely support blocks 23, which support the latch at the plug socket. The support blocks can be on the same side or different sides as the positioning column according to needs. In this example, different sides are used as examples for demonstration. Figure 1 , Figure 2 As shown, the positioning posts 22 are distributed at the front and rear sides, and the support blocks 23 are located at the left and right sides. The two are distributed in a cross shape as a whole, which is convenient for adapting to conventional plugs.

[0034] like Figure 3 , Figure 5 As shown, the fasteners 11 are arranged on both sides of the socket 14 of the plug 1, and the head end of the fastener 11 extends above the socket 14. When the cover 2 is placed on the socket, the support block 23 is located between the head ends of the two fasteners 11. The support block can directly abut the fastener or reserve an appropriate gap, such as Figure 5 As shown, according to the height of the head end of the buckle 11, the length of the support block is predetermined, and when the cover is placed in the socket, the head end of the buckle directly abuts the support block. The buckle is limited inwardly by the support block to avoid the buckle from rotating inwardly and causing damage.

[0035] In this example, the support blocks 23 are all tilted outwards and the ends of the support blocks 23 protrude outwards from the side of the plate body 21. The degree of tilting outwards is determined according to the structure of the latch at the docking plug. Figure 1 , Figure 5As shown in the figure, when the cover plate is moved downward and placed in the socket, it is necessary to meet the requirement that the end of the buckle 11 abuts against the outer side of the support block 23. During the downward movement of the support block, the buckle is urged to rotate outward to make room. The inclination degree of the support block and the like are determined according to the position of the end of the buckle of the docking plug. After the cover plate is installed in place, the buckle is reset, and the two support blocks 23 are located between the first ends of the buckle 11, and the top of the support block 23 abuts against the inner side of the first end of the buckle 11.

[0036] To improve the structural strength, a reinforcing rib 24 can also be formed between the inner side of the support block 23 and the top surface of the corresponding plate body 21.

[0037] The support block, the positioning post and the plate body can be separately and independently formed and assembled later. It is preferably integrally formed, such as by injection molding.

[0038] In addition, as Figure 4 shown in the figure, in this example, a slot 13 that is inserted and matched with the positioning post 22 is also formed at the end of the plug 1 opposite to the position of the socket 14. For example, the slot 13 is formed at the end face or side face of the plug end. The cover plate 2 removed from the socket can be placed at the end of the plug 1 opposite to the socket to avoid loss.

[0039] For the formation of the slot, to reduce the influence on the plug structure, in this example, a rib 12 is formed on the side of the plug 1, and the gap between the adjacent ribs at the side of the socket and the side of the end of the plug opposite to the socket forms the slot 13. The size, shape, etc. of the positioning post can be predetermined to meet the insertion with the gap between the adjacent ribs. For example, the positioning post is rectangular, cylindrical, T-shaped, trapezoidal, etc., and the shape of the slot is the same as that of the positioning post.

[0040] Regarding the structure of the buckle, as Figure 5 shown in the figure, the buckle 11 includes a wrench part 111, a hook part 112 and an elastic connecting part 113. A gap is maintained between the inner side of the wrench part 111 and the side of the plug 1 to facilitate pressing movement. The end of the wrench part 111 is connected to the end of the hook part 112. The connecting part 113 is strip-shaped, and one end thereof is located at or near the connection part between the wrench part 111 and the hook part 112. The other end of the connecting part 113 is connected to the side of the socket 14. When the wrench part is pressed, the hook part rotates outward. The buckle is preferably integrally formed with the plug. The first end of the L-shaped hook part 112 of the buckle is above the socket 14, and the first end of the support block 23 abuts against the first end of the hook part 112. For example, the hook end of the hook part is hooked to the first end of the support block.

[0041] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
