Description

Secondary socket

Technical Field

The utility model relates to an electric power wiring accessory technical field, concretely relates to secondary socket.

Background

The secondary plug-in is suitable for low-voltage draw-out type complete switch equipment, and the draw-out type functional unit realizes isolation or connection of auxiliary circuits (output and input). The structural design of current secondary socket is unreasonable, and when this secondary socket was pegged graft mutually with the secondary plug, the contact of the contact piece of secondary socket and secondary plug was unreliable, had the risk of instantaneous interruption to this secondary socket has the performance unreliable, assembles not convenient, connects insecure defect.

Disclosure of Invention

An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance are reliable, the assembly is convenient, connect reliable secondary socket.

In order to realize the above object, the utility model discloses a secondary socket, include the support, set up a plurality of socket subassemblies in the support respectively, socket subassembly include casing, two contact pieces, the casing include the pedestal, set up the apron on the pedestal, pedestal and apron between be formed with the grafting passageway, two contact piece symmetries set up in the grafting passageway, the one end of two contact pieces be provided with respectively and expose the binding post outside the casing, two contact pieces on have the protruding contact site of arc, the protruding contact site of arc of two contact pieces between be formed with and supply secondary plug male grafting space.

The beneficial effect of above-mentioned structure is: arc-shaped protruding contact parts are arranged on the two contact pieces, and when the secondary socket is plugged with the secondary plug, the arc-shaped protruding contact parts can be abutted against the secondary plug, so that the secondary socket can be more reliably connected with the secondary plug. And two contact pieces are clamped in the shell, so that the two contact pieces are convenient to assemble with the shell, and the assembly is more convenient. Therefore, the secondary socket has the advantages of simple structure, stable and reliable performance, convenience in assembly and reliability in connection.

Particularly, the other ends of the two contact pieces are provided with two limiting pieces, limiting grooves are arranged in the seat body corresponding to the two limiting pieces, and the limiting pieces are clamped in the limiting grooves and form limiting matching of the two contact pieces and the seat body. The two contact pieces and the base body are assembled in a limiting matching mode, so that the two contact pieces are connected with the base body more compactly, and the two contact pieces cannot be loosened.

Particularly, the base body is internally provided with a limit lug which is abutted against the two contact pieces and forms limit matching of the limit lug and the two contact pieces. The limiting convex block is abutted against the contact piece, so that the contact piece can be ensured to be reliably contacted with the secondary plug, and the working reliability of the secondary socket is improved.

Particularly, two contact pieces on be provided with the joint portion of bending respectively, the pedestal on be provided with the joint groove of the joint portion matched with of bending, the joint portion block of bending in the joint inslot, and constitute the joint cooperation of two contact pieces and pedestal. Two contact pieces and pedestal adopt the joint cooperation mode to be connected to the assembly of two contact pieces and pedestal of being convenient for, the assembly is more convenient.

Particularly, a guide inclined plane is arranged at the position, corresponding to the socket of the insertion channel, on the base body. The guide inclined plane can play a role in guiding the secondary plug, so that the secondary plug and the secondary socket can be reliably plugged.

Detailed Description

As shown in fig. 1-3, the embodiment of the present invention is a secondary socket, including support 10, a plurality of socket components 20 respectively arranged in support 10, socket components 20 include casing 21, two contact pieces 22, casing 21 include pedestal 211, set up the apron 212 on pedestal 211, pedestal 211 and apron 212 between be formed with grafting passageway 200, two contact pieces 22 symmetry set up in grafting passageway 200, two contact pieces 22 one end be provided with respectively and expose the binding post 23 outside casing 21, two contact pieces 22 on have arc protruding contact part 221, the arc protruding contact part 221 of two contact pieces 22 between be formed with and supply secondary plug male grafting space 220. The other end of the two contact pieces 22 is provided with two limiting pieces 222, limiting grooves 213 are arranged in the seat body 211 corresponding to the two limiting pieces 222, and the limiting pieces 222 are clamped in the limiting grooves 213 to form limiting matching of the two contact pieces 22 and the seat body 211. Two contact pieces and pedestal adopt spacing cooperation mode assembly to can guarantee that two contact pieces are compacter with being connected of pedestal, two contact pieces can not loosen and take off. The base body 211 is provided with a limit bump 214 respectively abutting against the two contact pieces 22, and the limit bump 214 is in limit fit with the two contact pieces 22. The limiting lug is abutted against the contact piece, so that the contact piece can be ensured to be reliably contacted with the secondary plug, and the working reliability of the secondary socket is improved. Two contact pieces 22 on be provided with the joint portion 223 of bending respectively, pedestal 211 on be provided with the joint groove 215 that bends joint portion 223 matched with, the joint portion 223 block of bending in joint groove 215, and constitute the joint cooperation of two contact pieces 22 and pedestal 211. Two contact pieces and pedestal adopt the joint cooperation mode to be connected to the assembly of two contact pieces and pedestal of being convenient for, the assembly is more convenient. A guiding inclined plane 216 is arranged on the seat body 211 corresponding to the socket of the plugging channel 200. The guide inclined plane can play a role in guiding the secondary plug, so that the secondary plug and the secondary socket can be reliably plugged.

Arc-shaped protruding contact parts are arranged on the two contact pieces, and when the secondary socket is plugged with the secondary plug, the arc-shaped protruding contact parts can be abutted against the secondary plug, so that the secondary socket can be more reliably connected with the secondary plug. And two contact pieces are clamped in the shell, so that the two contact pieces are convenient to assemble with the shell, and the assembly is more convenient. Therefore, the secondary socket has the advantages of simple structure, stable and reliable performance, convenience in assembly and reliability in connection.
