Abstract
The utility model relates to a terminal box which comprises a box body, a box cover, a metallic connecting piece on a wire holder, and connecting joints, wherein, the wire holder for connection is arranged inside the box body; the metallic connecting piece is arranged on the wire holder; the box body and the box cover are connected with each other through involution; the connecting joints for connecting plugs to insert in are distributed on the side face of the box body. The utility model is characterized in that: a card is arranged on the side face of the box body close to the connecting joints; clamping feet are arranged on the card; correspondingly, clamping teeth matching with the clamping feet are formed on the nut surface of the connecting joints. The utility model has the advantages of simple and practical structure, difficult to loosen of nuts, capability of making the connection of plug components be more stable and longer, improvement of use safety, easy production, low cost and good effect.
Description
Technical field
The utility model relates to the terminal box in a kind of electric appliance component.
Background technology
At present, in China's electron trade, connect the general compression joint type connection that locks electric wire with screw of adopting for lead, this connected mode will can be finished the wiring process by corresponding instrument, and wiring speed is slow, also usually come off for screw occurring, loss and stripped thread phenomenon, influence connects electric safety and operate as normal, causes man power and material's waste again; In addition, the screw of this its connection of the mode of connection usually is outside being exposed to, the careless danger that also has electric shock.The inventor has at length reported a kind of terminal box of capable of being combined and dismounting in the patent No. is 03232075.2 Chinese patent " quick connector " for this reason.In the patent No. is that 03232075.2 Chinese patent also discloses another kind of terminal box.They all improve to some extent, and have certain progressive meaning.But, a fly in the ointment is, the wiring joint that they are provided with on box body for the plug-assembly insertion, generally be to adopt nut to fix plug-assembly, by the fluting flexible flaps on the nut screwing clamping compressing wiring pipe fitting, the wiring joint is connected fast go up plug-assembly, in using, practice shows, this connection also exists improvement necessary, because nut is by being threaded on the wiring pipe fitting time one length, loosening easily, cause nut can't compress the fluting flexible flaps, plug-assembly is deviate from from the wiring joint easily, cause the accident.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple and practical, nut to be not easy to become flexible, make plug-assembly to connect firm more permanent terminal box at existing background technology.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of terminal box, it includes box body, lid, metal connecting piece on the junction block, the wiring joint, wherein be provided with in the box body to be distributed with to connect and use junction block, metal connecting piece is arranged on the junction block, box body and lid are involutory to be formed by connecting, the box body side is distributed with the wiring joint that inserts for connection plug, it is characterized in that described box body side is being provided with card near the wiring joint area, have card base on the card, accordingly, the nut of wiring joint surface ring week forms the latch that cooperates with card base.
As improvement, described card is the position, both sides that is arranged on the wiring joint in couples, makes stressed more even.
At last, described card is made of one structure with box body.
Compared with prior art, advantage of the present utility model is: simple and practical, nut is not easy to become flexible, and it is firm more permanent that plug-assembly is connected, and improves the fail safe of using, and manufactures easily, with low cost, effective.
Description of drawings

Fig. 2 is the partial structurtes enlarged drawing (forward) of the utility model terminal box;
Fig. 3 is the exploded view of the utility model terminal box.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Anticipate as Figure 1-3, a kind of terminal box, it includes metal connecting piece, wiring joint on box body 1, lid 2, the junction block, wherein be provided with in the box body 1 to be distributed with to connect and use junction block, metal connecting piece is arranged on the junction block, box body 1 and lid 2 involutory being formed by connecting, box body 1 side is distributed with the wiring joint 3 that inserts for connection plug, it is invented crucial part and is that box body 1 side is being provided with card 4 near the wiring joint area, have card base 5 on the card 4, accordingly, the 6 surface ring weeks of nut of wiring joint form the latch 7 that cooperates with card base.As improvement, card 4 can be the position, both sides that is arranged on wiring joint 3 in couples.Card 4 is to be made of one structure by plastics molding process and box body 1.
Its operation principle is such, after plug-assembly is inserted into wiring joint 3, the hand-tight make-up nut 6 then, nut 6 is under the promotion of staff, make latch 7 on the nut can overcome card base 5 on the card 4, constantly tighten, thereby plug-assembly is fixed on the wiring joint 3, and after moving outside the hand, card base 5 on the card 4 is returned to the origin-location under elastic reaction, be stuck in engagement on the latch 7 on the nut 6, can prevent effectively that nut from falling back back, plug-assembly can for a long time firmly be connected on the wiring joint 3, can not become flexible.
