Description

Secondary plug

Technical Field

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

Background

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

Disclosure of Invention

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

In order to achieve the purpose, the utility model discloses a secondary plug, include the mounting bracket, set up multiunit plug assembly in the mounting bracket side by side, plug assembly include plug, apron, set up two contact pieces on the plug both sides respectively, the apron setting on the plug, and be formed with two centre gripping spaces between apron and the plug, two contact pieces block respectively in two centre gripping spaces, contact piece one end be provided with binding post, the other end of contact piece has the contact site, is provided with the protruding muscle of contact on the contact site.

The beneficial effect of above-mentioned structure is: the contact convex rib is arranged on the contact part of the contact piece, so that the contact pressure of the contact piece is improved, the contact of the contact piece and the secondary socket is more reliable, the contact piece is clamped between the plug and the cover plate, the contact piece is convenient to assemble with the plug and the cover plate, and the assembly is more convenient. Therefore, the secondary plug has the advantages of simple structure, stable and reliable performance, convenience in assembly and reliability in connection.

Particularly, the tail part of the contact part is provided with a bending limiting part, the plug is provided with a limiting groove corresponding to the bending limiting part, and the bending limiting part is clamped in the limiting groove and forms clamping fit of the contact part and the plug. The bending limiting part of the contact part is clamped in the limiting groove, so that the contact part and the plug can be connected more compactly.

Particularly, an elastic supporting sheet is arranged on the plug corresponding to the middle of the contact part and abuts against the lower end face of the contact part. The elastic support piece can increase the contact pressure of the contact part and can ensure the connection reliability of the secondary plug.

Particularly, the elastic supporting sheet is provided with a limiting block which is abutted against one side of the contact part, and the contact part is in limiting fit with the limiting block. The limiting block is abutted against one side of the contact part, so that the contact part can be more compactly connected with the plug, and the contact part can be prevented from loosening and falling off.

Particularly, the contact strip on have the joint portion of bending, the plug 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 plug and contact piece. The contact piece is clamped in the clamping groove of the contact, so that the connection between the contact piece and the plug can be more compact, and the working reliability of the secondary plug is improved.

Detailed Description

As shown in fig. 1 and 2, the embodiment of the present invention is a secondary plug, including the mounting bracket 10, set up multiunit plug assembly 20 in the mounting bracket 10 side by side, plug assembly 20 include plug 21, apron 22, set up two contact pieces 23 on plug 21 both sides respectively, apron 22 set up on plug 21, and be formed with two centre gripping spaces 200 between apron 22 and the plug 21, two contact pieces 23 block respectively in two

centre gripping spaces

200, 23 one end of contact piece be provided with binding post 231, the other end of contact piece 23 has contact part 232, is provided with the protruding muscle 234 of contact on the contact part 232. The tail of the contact part 232 is provided with a bending limiting part 235, the plug 21 is provided with a limiting groove 211 corresponding to the bending limiting part 235, the bending limiting part 235 is clamped in the limiting groove 211, and the contact part 232 is in clamping fit with the plug 21. The bending limiting part of the contact part is clamped in the limiting groove, so that the contact part and the plug can be connected more compactly. An elastic supporting piece 212 is arranged in the middle of the plug 21 corresponding to the contact portion 232, and the elastic supporting piece 212 abuts against the lower end face of the contact portion 232. The elastic support sheet can increase the contact pressure of the contact part and ensure the connection reliability of the secondary plug. The elastic support piece 212 is provided with a limit block 213 which is pressed against one side of the contact part 232, and the limit fit of the contact part 232 and the limit block 213 is formed. The limiting block is abutted against one side of the contact part, so that the contact part can be more compactly connected with the plug, and the contact part can be prevented from loosening and falling off. The contact piece 23 on have the joint portion 236 of bending, the plug 21 on be provided with the joint groove 214 of bending joint portion 236 matched with, the joint portion 236 block of bending in joint groove 214, and constitute the joint cooperation of plug 21 and contact piece 23. The contact piece is clamped in the clamping groove of the contact, so that the connection between the contact piece and the plug can be more compact, and the working reliability of the secondary plug is improved.

Be provided with the protruding muscle of contact on the contact site of contact piece, be favorable to improving the contact pressure of contact piece to can guarantee that the contact of contact piece and secondary socket is more reliable, and the contact piece block is between plug and apron, thereby the assembly of the contact piece of being convenient for and plug, apron, it is more convenient to assemble. Therefore, the secondary plug has the advantages of simple structure, stable and reliable performance, convenience in assembly and reliability in connection.
