Abstract

The utility model provides an electric wire connecting card, which is in a 'T'-shaped tubular structure which is formed by hinging with an upper card seat and a lower card seat by a pin shaft, wherein a screw thread structure on the leading-out terminal of a branch line in the electric wire connecting card is matched with a locking screw cap to play a part in fixing and compacting. A tubular space structure which is formed by the upper card seat and the lower card seat under the locking status is internally provided with an elastic conducting strip which is connected with a branch leading-out line and is fused on the lower card seat. The centers of the leading-out terminals of the branch lines of the upper card seat and the lower card seat are provided with grooves and tenons which are mutually corresponding with each other to play a part in location. Under the locking status of the upper card seat and the lower card seat, the inner side of the tubular space which is visible at the end faces of the two sides is provided with a structure for tightly pressing a guide line insulation layer. The inner wall of the tubular space is provided with a layer of elastic soft cushion layer so as to guarantee a metal lead to be reliably contacted with the elastic electric conduction piece. The surface of the locking screw cap is provided with anti-skidding thread.

Description

Wiring card

Technical field

The utility model relates to a kind of clamping apparatus that is used for electric wire, cable connection.Especially for a kind of Quick Connect Kit of on basic routing line, drawing branch's lead-in wire.

Background technology

At present in the installation and maintenance process of industry and civil buildings electric wiring, usually the main method that adopts has 2 kinds: for example when mounting receptacle, first method is as interface with the terminals of each socket (post), make it to gang up with a wire, reach the purpose of a plurality of sockets in parallel in an electric loop, the shortcoming of doing like this is that whole circuit just has a breakpoint in the position of terminals respectively, this breakpoint is to bring in connection by the wiring of socket, if the socket of front end goes wrong, will certainly have influence on the normal use of the socket of back; Second method is under the situation that does not disconnect basic routing line, and " T " picks out a bit of lead-out wire on the line, and then inserts socket, the potential influence that so just can avoid first kind of installation method to bring by lead-out wire; But such method can be subject to operating personnel's technical capability and qualification, should twine the 6-8 circle by the regulation and stipulation branch line on basic routing line is advisable, but because the external diameter of backbone and branch line is different, the length that will accurately estimate the lead that need separate in advance is not easy to accomplish, if it is not enough or twine untight words to twine the number of turns, it is bigger than normal to produce contact resistance, and the wiring position has the hidden danger of heating; And final shaping is not attractive in appearance, and quality is uneven, and efficient is not high yet, especially is being awkward especially than narrow space, stays hidden danger of quality.

The utility model content

At above-mentioned situation, the utility model provides a kind of jockey of drawing branched line fast on basic routing line.Two semicanal type T shape members that link is continuous are fastened on the metallic conduction part of trunk lead, make its connection that can carry out circuit fast, easily combination.

Basic structure form of the present utility model is hinged manner.Main body is two "T"-shaped tubular structures that similar semicanal type T shape component composition forms, and its two parts are associated in together by linked set, and the hollow part is equipped with the structure with lead conductor clamping or crimping, and links to each other with the branch lead-out wire.The a bit of screw thread and the conical surface are arranged on the branch end of "T"-shaped tubular structure, the nut that matches with it can be fixed as a whole, and be provided with groove and the tenon structure that to locate in the centre of branch's exit, guarantee that two semicanal type T shape members can accurate in locating behind fastening.Two end face area inboards at "T"-shaped tubular structure are useful on the structure that compresses wire insulation, when snapping together, two semicanal type T shape members can compress the insulating barrier on the lead, prevent that the metal that conducts electricity from partly exposing from the wiring card two ends, and can prevent wiring card sliding transfer on lead.Inwall in the cast space has one deck elastic cushion layer, when two semicanal type T shape members snap together, elastic conducting strip is formed certain pressure, guarantees that plain conductor reliably contacts with elastic conducting strip.

The using method of the wiring card of the utility model said structure form is very simple.Needs install branch line the trunk lead on strip out the metallic conductor of suitable length, exposed plain conductor is connected in the elastic conducting strip, fasten two semicanal type T shape members, use the nut that is inserted in by the branch line exit to tighten, can on the trunk lead, connect required branch's lead-in wire.Be appreciated that thus above-mentioned operation is not only convenient and swift, even and if also can finish more easily at the small space that is awkward.

According to foregoing, under the prerequisite that does not break away from the above-mentioned basic fundamental thought of the utility model,, modification, replacement or the change of various ways can also be arranged to its content according to the ordinary skill knowledge and the customary means of this area.

Below in conjunction with the embodiment of drawings attached illustrated embodiment, foregoing of the present utility model is described in further detail again.But this should be interpreted as that scope of the present utility model only limits to following example.All technology that is realized based on the utility model foregoing all belong to scope of the present utility model.
