Abstract
The utility model relates to a branching joint for a connection box, which is suitable for conducting branching T connection for cables in a supply line of a high building. The utility model is provided with a strip-shaped insulated joint seat of which both ends are provided with a wiring clip, and the utility model is provided with locking screws. When the utility model is used, perpendicular input cables of each layer are not needed to be cut, and the branching T connection can be conducted. Therefore, the utility model saves wire material, simplifies the structure of the connection box, reduces the size of the box body of the connection box and raises further the conveying reliability and safety of conducting wires.
Description
The utility model relates to a kind of being suitable for and in the supply line of high buildings and large mansions cable or wire is carried out junction box's branch joint that the T of branch connects, and it is disposed at the junction box, and the controller switching equipment performance of occasion electric power systems such as skyscraper is further improved.
At present, in the power supply distribution line of some occasions such as high buildings and large mansions, the T of branch of cable or wire connects the normal disjunction formula that adopts among the junction box, be under every layer of electric wire during to following one deck, electric wire is blocked, and junction box's upper end porcelain knob is inserted in electric wire lower end, upper strata, and lower floor inserts junction box lower end porcelain knob in the electric wire upper end, upper and lower porcelain knob links to each other with copper bar, and this layer outlet is then by telling with being connected of copper bar.The junction box adopts this kind structure accessory to come separated time to have following problem: one, it is many to connect the position, complex structure, and the size of junction box's casing is big, they are two years old, cable or wire is blocked, and will cause no small waste to cable and lead, and also ten minutes trouble of connection is installed, the 3rd, connect the position and be easy to produce the phenomenon of loose contact more,, influence the transportation performance of whole circuit down to accidents caused.
The purpose of this utility model is to provide a kind of junction box's branch joint that need not block transportion wire and make junction box's structure obtain simplifying at the deficiency of above-mentioned existence.
The purpose of this utility model is realized by following technical scheme: has the insulating joint seat 1 of a strip and block, is provided with binding clip 4 at the two ends of insulating joint seat, and configuration lock-screw 3.
According to such scheme, during use, every layer vertical input cable need not to block in the junction box again, only needs strip off one economize on electricity cable, the cable core of strip off is pressed to be clipped on the binding clip then, connects the outlet of drawing this layer from binding clip again, can finish the task that the T of branch connects.The utility model is not owing to block cable, thereby not only saved wire rod, dwindled the space of wiring separated time among the junction box, simplified junction box's structure, junction box's box sizes dwindled, and can improve lead delivery reliability and fail safe further.
Fig. 1 is the front view of an embodiment of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the top perspective view of the utility model user mode.
An embodiment of the present utility model such as Fig. 1, shown in 2, I shape insulating joint seat 1 with a strip, offer arc groove and set binding clip 4 at the two ends of insulating joint seat, the last lower clamping piece that binding clip is arched by the middle part is formed, lock-screw 3 by both sides links to each other with the insulating joint seat, for ease of installing of lock-screw, can offer straight trough 5 corresponding to lock-screw in the both sides of two terminations of insulating joint seat, the rear end of straight trough is established the groove shoulder and is laid nut 6 and connects with lock-screw 3, in addition, the interlude of insulating joint seat also offers connecting hole 2, about two, be used for linking with junction box's supporting frame plate 7.
The user mode situation of the utility model in the junction box as shown in Figure 3, be fixed on the supporting frame plate 7 that overhangs in the junction box by screw 9 from a distance with two branch joints, the I-shaped of insulating joint seat faces up vertical with the lead of cross-under, binding clip on 4 terminations of two branch joints is 3 live wires of cross-under and 1 zero line respectively, the T of branch of every phase connects also and draws from binding clip simultaneously, supporting frame plate 7 joins by the flanging 10 of inboard and the base plate among the junction box, and the outboard end of supporting frame plate can be installed ground wire intermediate plate 8.
