Abstract
The invention relates to a wiring connection structure for a buried wiring switch socket base box, comprising two or more box bodies, wherein threading holes are formed at the side edges of the box bodies, and blind holes are formed at the four corners of the bottom wall inside the box bodies; a fixing stud and a trimming stud for fixing a switch socket panel are arranged at two inner sides of the box body perpendicular to the inner bottom wall; the base boxes are connected by means of a base box connecting piece; the base box connecting piece comprises a base box connecting sheath and two hexagonal external threaded pipe joints respectively matching the internal threads at the two ends of the base box connecting sheath, which facilitates adjustment of the levelness, the perpendicularity and the distance between centers after the two base boxes are connected, thereby preventing the cement motor from infiltrating the base boxes; a line pipe joint comprises a line pipe connecting sheath and a line pipe external thread joint, and a circular arc corner is formed at the place where the hexagonal flange end face of the joint and the central hole intersects, thereby avoiding cutting wires or signal/data lines; and the shortest distance between the edges of the threading holes and the outer end faces is 13-16mm, which increases the thickness between the line pipe and the cement motor on the wall surface, increasing the strength and preventing the wall surface from cracking.
Description
Technical field
The present invention relates to building materials field, specifically is a kind of recessed switch socket back box wire connection structure.
Background technology
Existing recessed switch socket back box structure is a cubic box; All be to be embedded in the body of wall during installation, only expose the combined socket and switch cover plate again above the wall, when a plurality of recessed switch socket back of needs box is installed side by side; The normally used method of upfitter is range estimation or with the distance of each end box of tape measure assessment and just; And then landfill cement is husky fixing, and this construction method is unstable, and whether the arrangement of end box neatly is difficult to hold.To this problem; Go out case connecting structure of a kind of end on the market; The end box of this structure is that the box two corresponding outsides are provided with caulking groove and abaculus respectively the end of at, and two end boxes are connected with abaculus through caulking groove, yet though should connect more stable than original; But end box is in the landfill cement mortar, and it is dirty and occupy box space, the end that cement mortar infilters box lanes and alleys, the end from the through wires hole between two end boxes easily.Moreover, the end box of this structure and the joint of spool normally adopt pipe box and male connection; Because the right angle, edge that the end face of flange of male connection and endoporus intersect is more sharp-pointed; During installation, after being fixed on the body of wall, sometimes need spur electric wire or holding wire or data wire to end box; Sharp-pointed right angle exposes the metal core to the insulation sheath of electric wire or holding wire or data wire incised wound easily, exposes the metal core and has grown to make moist easily service time and be short-circuited even initiation fire.In addition, the through wires hole of the end box of these structures since from the distance of outside end face about 10mm, when end box is embedded in when filling in cement mortar in the wall; Spool is shorter from the distance on wall surface; It covers the thinner thickness of cement mortar, and intensity is lower, and the time has been grown the metope cracking that makes this part easily.
Summary of the invention
The objective of the invention is to above-mentioned existing problems and deficiency, provide to connect between the box of a kind of end and stablize neatly, prevent that cement mortar from infiltering end box, being hurt, prevent to cover the recessed switch socket back box wire connection structure that metope ftractures on the spool when avoiding electric wire or holding wire or data wire pulling.
Technical scheme of the present invention is achieved in that a kind of recessed switch socket back box wire connection structure; Comprise two or more box bodys; The side of said box body is provided with through wires hole; Diapire is provided with blind hole for four jiaos in the box body, and diapire was provided with the fixed bolt and fine setting double-screw bolt of floatless switch socket panel in box body two inner side edges were vertical, also comprised:
Two end box connectors; Box connector of the said end comprise end box adapter sleeve and respectively with two hexagonal male connectors of the screw-internal thread fit at box adapter sleeve two ends, the end; The hexagonal male connector is a hollow bolt; The one of which end is provided with connector hexagonal flange, and connector hexagonal end face of flange and mesopore intersect the position and be provided with the cut-protection arc chord angle, and the outside dimension of connector hexagonal flange is bigger than through wires hole diameter dimension; The end outer surface of box adapter sleeve is provided with kerve; End box adapter sleeve is provided with and the suitable internal thread of the external screw thread of hexagonal male connector, and said two hexagonal male connectors match with the internal thread at box adapter sleeve two ends, the end and are fixed together two end box box bodys from the interior through wires hole that passes two box bodys outward through its screwed pipe respectively;
The spool joint; Said spool joint comprises that spool connects pipe box and spool male connection; Said spool male connection is a hollow bolt; The one of which end is provided with joint hexagonal flange, and the outside dimension of joint hexagonal flange is bigger than through wires hole diameter dimension, and said joint hexagonal end face of flange and mesopore intersect the arc chord angle that the position is provided with cut-protection electric wire or signal or data wire; The endoporus that said spool connects pipe box one end is provided with and the suitable internal thread of the external screw thread of spool male connection, and the other end diameter of bore of spool connection pipe box and the external diameter of spool are suitable.
In order to increase the thickness of spool from the wall surface, prevent to cover the metope cracking on the spool, the beeline of the edge of said through wires hole far from the box body outer face is 13-16mm.
In order to increase frictional force, improve simultaneously and cement mortar between adhesive strength, the outer surface that said spool connects pipe box and spool male connection link is provided with anti-skidding line.
For making end box connector be fit to the switch jack panel of different model, the length of end box adapter sleeve is 13-40mm.
The present invention is owing to adopt end box connector to connect between two end boxes; The structure of end box connector comprise end box adapter sleeve and respectively with two hexagonal male connectors of the screw-internal thread fit at box adapter sleeve two ends, the end, can be convenient to two end boxes are coupled together levelness, perpendicularity and center distance after box connects at the bottom of two of the convenient adjustment; It is smooth stable that two end boxes connect the back; Can prevent during installation that cement mortar from infiltering in the end box from through wires hole, guarantee that end box is inner clean, has also avoided cement mortar to occupy box inner space, the end; End while box adapter sleeve outer surface is made kerve, is beneficial to the adhesive strength between raising and the cement mortar; Intersect the structure that the position is provided with fillet at joint hexagonal end face of flange and mesopore, when circuit and maintenance circuit being installed needing pulls wire, prevent to hurt electric wire or signal or data wire; The edge of through wires hole is the structure of 14-16mm far from the beeline of outer face, has increased the thickness of spool from wall wash cement mortar, has improved the intensity of later stage sealing groove cement mortar, has prevented that the metope wire casing from criticizing the cover cracking.
Below in conjunction with accompanying drawing the present invention is further described.
