Description

The cellular-type Safety terminal box

The utility model relates to a kind of electric and electronic circuit annex, specially refer to a kind of in lead connection, separated time, intersection, bunchy, (plate) through walls, cross the pipe place and require occasions such as insulation, thermal insulation, electromagnetic shielding, damp proof insulation, dustproof, corrosion protection, wear-resisting, crashworthiness lead middle and terminal attachment of employed electric and electronic circuit and when layer being stereo structure and separating by row, column.

Existing such electric and electronic circuit annex has terminal box, porcelain connector, junction box, porcelain bushing, crosses wall dividing plate etc.They or be electrically connected poor performance, dangerous phenomenon such as easily produce contact resistance increase, loose contact, open circuit; Perhaps out of phase or current potential lead are crowded together, have hidden danger such as short circuit, be not suitable for heavy current circuit especially; Perhaps distributed capacitance is big; Perhaps inconvenience is installed and is taken off, changes; Perhaps a place uses many, and it is big to take up space, and seems very too fat to move.

The purpose of this utility model is, be electrically connected the good advantage of performance, separate the function of lead, the purposes that is fit to specific environment and requirement, beautifying and decorating effect etc. and roll into one what above-mentioned annex had respectively, design a kind of novel, safe and reliable electric and electronic circuit annex.

Briefly, the utility model comprises three partly.First is a box body, is provided with the projective structure with box body design one group of post that is parallel to each other of all-in-one-piece (sheet, plate, band, grid etc.) shape; One group connects box body becomes box (pipe, tube etc.) shape closed container with lid syndeton, and the position of syndeton needs to decide on separation.Projective structure and syndeton can be separated according to phase sequence the lead that is contained in the box by row, column.Second portion is a lid, is provided with and one group of syndeton that matches with syndeton on the box body of lid design all-in-one-piece; One group on box body projective structure fixedly the time with its jack that matches (groove).They with on the supporting box body structure play compartmentation jointly.The box ear and the lead that cover and open usefulness can be set on box body and the lid import and export, convex tendon and the thick edge rigidity with strengthen box can be set, colour-coded can be set indicate phase sequence.Box body and lid are the indispensable two parts of the utility model.Box can be designed to shape closed containers such as box that profile is appearance such as polyhedron, rotary body, ring body, cylinder, cone, stage body, object or animals and plants, pipe, tube as required; Be designed to various colors and pattern.Third part is a dividing plate, and the clamp port (hole, groove) of usefulness is put into and taken out in through wires hole (groove, mouth), the confession of be provided with the embedded hole (groove, mouth) that passes for aforementioned projective structure and syndeton, passing for lead.Dividing plate can be stereo structure according to the branch road order by layer and separates being contained in lead in the box.Whether the dividing plate setting reaches that piece is several to be decided according to the branch road layering needs.The structure of box body, lid and dividing plate, shape, size, Material Selection, the position of projective structure and syndeton, quantity, shape etc., all according to lead be in that butt joint, T-shaped connect, cross joint, separated time, change fork, bunchy, (plate) through walls and cross pipe, single-phase, phase three-wire three and three-phase and four-line, little electric current and current state, and require occasion such as insulation, thermal insulation, electromagnetic shielding, damp proof insulation, dustproof, anticorrosion corrosion, wear-resisting, crashworthiness and decide, with suitable simply attractive in appearance being advisable.Edges and corners are with round-corner transition.In case of necessity, box body and lid joint can be designed to helicitic texture or import and export with lead that be designed to can be by material seals such as the insulation of environment for use requirements usefulness, thermal insulation, damp proof insulation, secluding airs.The visual material of three parts (as plastics, porcelain, cast iron) with injection moulding, fire, technology one-shot forming such as casting, punching press.

The major function of the annex of the multiple class purposes of the existing electric and electronic circuit of the utility model case and advantage are, it is little to have the terse compact volume of structure, the simple cost of manufacturing process is low, it is wide that the convenient purposes of replacing is installed, it is good to be electrically connected performance, characteristics such as personnel's equipment safety operation is reliable, also have the beautifying and decorating effect, can be used for single-phase and three-phase, the lead of little electric current and heavy current circuit is connected, separated time, intersect, bunchy, (plate) through walls and pipe place and requirement insulation excessively, adiabatic, electromagnetic shielding, moistureproof, dustproof, the anticorrosion corrosion, wear-resisting, occasions such as crashworthiness.
