Description
Technical field
The utility model relates to a kind of Built-in terminal box, particularly a kind of metal connection magazine.
Background technology
In architectural engineering or all kinds of decoration construction, Built-in terminal box is necessary electrician's aid, can play the connection electric wire, the transition of various electric appliance circuits, the effect of protection circuit safety.Built-in terminal box mainly is divided into metal material and PVC material, the Built-in terminal box of metal material is better than the Built-in terminal box of PVC material at aspects such as earthing type, fire protecting performance, hardness, and the Built-in terminal box insulation property of PVC material are better, can select according to varying environment the Built-in terminal box of unlike material during construction.
For keeping the neat and artistic of building sides, Built-in terminal box generally all needs to carry out pre-buried installation.Therefore,, for the Built-in terminal box of metal material, be embedded in interior of building and need possess certain sealing property, prevent that silt from entering box body inside; Also to have certain rustless property, prevent from affecting because getting rusty at interior of building use.Have in prior art and adopt complete stretch to obtain Built-in terminal box, although one-body moldedly reach good sealing property, but because stretched portion is larger, be easy in forming process form cut at box surface, not only outward appearance is not beautiful, in use, the rustless property at these cut place a little less than, box body also easily starts to get rusty from this.In addition, the full Built-in terminal box that stretches is had relatively high expectations to material, and need reserve larger surplus to meet operation requirements, has caused the waste of material.
, for avoiding the problems referred to above, box body can be divided into the plurality of plates assembled formation.Modal is that the metallic plate of polylith well cutting is welded along the sidewall connecting line.But welding can form crator, stain at box surface, causes the box body that obtains not attractive in appearance.Therefore, also occurred adopting the mode of riveting to connect the Built-in terminal box of polylith metallic plate.For example, the disclosed terminal box of Chinese patent literature CN201927959U, comprise body and two baffle plates, the two relative sides that described body is provided with bottom surface and with described bottom surface, is connected, form an opening shape box body after described body and two described baffle plate assemblings, be equipped with a plurality of fixed legs to described box body internal protrusion on described bottom surface and two described sides, described fixed leg consists of a plurality of stators, and is provided with gap between stator; Two described baffle plates are provided with a plurality of described stators fixing hole of correspondence respectively.Insert in fixing hole corresponding on described baffle plate by the fixed leg with on described body, more a plurality of stators that will form fixed leg are dispersion shape and are pressed on baffle plate, and then play fixation.Aforesaid way, avoided the not beautiful problem of outward appearance that adopts welding to cause, and can guarantee stable fixing.But, also there is following problem: in the prior art, by being molded over the fixing hole on box body, and be arranged on box body with fixing hole and be used in conjunction with, afterbody is provided with that the fixed leg that is dispersion shape is used in conjunction with, when box body is made, the technique that needs to increase the moulding fixing hole and make a plurality of stators of fixed leg and fixed leg, thus cause the production cost of product itself and the increase of difficulty.
The utility model content
For this reason, technical problem to be solved in the utility model is that Built-in terminal box of the prior art processing, assembling process are complicated and loaded down with trivial detailsly causes the production cost of Built-in terminal box itself and the problem that difficulty increases, and then provides that a kind of specious, good airproof performance, processing are simple, the rear firm Built-in terminal box of assembling.
For solving the problems of the technologies described above, Built-in terminal box of the present utility model comprises: body, the side plate that described body comprises top board and is positioned at described top board both sides; The side assembled plate, described side assembled plate has two, is assembled in respectively on described body, is suitable for being connected to form uncovered box body with the end of described top board and side plate; Base plate, be connected with described side plate and described side assembled plate, forms sealing box body; Between described body edges and described bottom edge, between described body edges and described side assembled plate edge, be respectively equipped with the section of being connected between described bottom edge and described side assembled plate edge, the described section of being connected comprises projection and is suitable for described projection and embeds the groove that connects.
Described projection and described groove are interference fit, are suitable for adopting cold punching power to make after described projection and described groove stress deformation closely chimeric.Certainly, it is not unique mode that the mode of employing cold punching force deformation makes described projection and described groove closely chimeric, also can utilize the character of expanding with heat and contract with cold of material, make described projection and described groove be in respectively under different temperatures, and then generation deformation, fasten again, it can be guaranteed closely chimeric under normal temperature and working temperature.
Described projection is rectangle, and the height of protrusion equals to make the thickness of the sheet metal of Built-in terminal box.
Described body is formed in one, and described top board is provided with the KO hole of drawing and forming.The KO hole is used for passing of electric wire, cable etc., and while not using, the available lid that coordinates with it covers.
Described side assembled plate, described side plate, described base plate are provided with several and can strike hole.
The area of the rectangle that the area of described base plate surrounds greater than described side plate and described side assembled plate, the edge of described base plate forms the fixing hole of fixing described Built-in terminal box.
Built-in terminal box described in the utility model has the following advantages:
(1) Built-in terminal box described in the utility model, in each face joint setting section that is connected, the section of being connected comprises projection and groove, described projection and described groove are suitable for mutually chimeric.Projection embeds the connected mode of groove, not only avoided adopting the not U.S. problem of outward appearance of welding, and processing is simple, only need to cut more or cut less along edge the sheet material of pre-sizing when cutting metallic plate, can form described projection and described groove, its assembling process is easy operating also, only described projection and chimeric the linking closely of described groove is got final product, reduce the difficulty of production, assembling, also saved human cost.
(2) be interference fit with described projection and described groove, can guarantee that described projection and described groove are closely chimeric.Not only guaranteed sealing, the sheet material of each assembling of Built-in terminal box that obtains can firmly be connected.
(3) the described projection of Built-in terminal box described in the utility model is rectangle, and the height of protrusion equals to make the thickness of the sheet metal of Built-in terminal box.Such design, after described Built-in terminal box assembling was completed, described projection can not given prominence to the surface of box body, can save material, has guaranteed the attractive in appearance of box body yet.
(4) described body is formed in one, and described top board is provided with the KO hole of drawing and forming.Direct drawing and forming KO hole on described body, stretched portion is less, is not prone to the surface scratch of drawing process, and comparatively saves material.
