Abstract
The utility model discloses a kind of terminal box, comprise terminal block housings and connector cover, described terminal block housings offers wiring hole, described terminal block housings inside is also provided with leg, and described leg solderless wrapped connection string holes edge is fixed on terminal block housings.Described leg offers chamfering away from wiring hole and with one end of line contacts.Main purpose of the present utility model is that providing a kind of plays certain protective role to electric wire, and the terminal box that coefficient of safety is more increased.
Description
Technical field
The utility model relates to electric component field, and more particularly, it relates to a kind of terminal box.
Background technology
In electric wiring; terminal box is one of electrician's auxiliary material; because the electric wire in electric wiring is poling or walks cable testing bridge, and at the joint area of electric wire, such as circuit is long; or conduit wants corner; just adopt terminal box as transition use, conduit is connected with terminal box, and the electric wire inside spool links up in terminal box; play protection electric wire and the effect being connected electric wire, this is exactly terminal box.
Due to the effect of terminal box, need to offer wiring hole so result on terminal box body, facilitate the access of circuit and pick out.And traditional terminal box, the setting of this wiring hole, being only simple through hole is arranged, and such setting, will produce some problems.Electric wire, through after wiring hole, often has bending, and when this bending, wiring hole will produce friction to the epidermis of electric wire, produces adverse influence to electric wire, reduces its useful life, turn increases security risk during use.
Utility model content
For the deficiency that prior art exists, main purpose of the present utility model is that providing a kind of plays certain protective role to electric wire, and the terminal box that coefficient of safety is more increased.
For realizing above-mentioned main purpose, the utility model adopts following technical scheme: a kind of terminal box, comprise terminal block housings and connector cover, described terminal block housings offers wiring hole, described terminal block housings inside is also provided with leg, and described leg solderless wrapped connection string holes edge is fixed on terminal block housings.
By adopting technique scheme; the setting of leg; can increase the length of wiring hole to a certain extent, such electric wire is when passing from wiring hole when electric wire, and wiring hole can have larger contact area; which increase contact area; reduce pressure, thus the effect of protection is served to electric wire, add useful life; be not easy the epidermis of electric wire to gall, more there is safety guarantee.
The utility model is set to further: described leg offers chamfering away from wiring hole and with one end of line contacts.
The utility model is set to further: described wiring hole offers chamfering towards one end of terminal block housings outside.
By adopting technique scheme, at electric wire through after wiring hole, the phenomenon of bending can be produced unavoidably, and this bending can have a friction with the edge of wiring hole, so just certain impact is created on the life-span of electric wire, electric wire is easily worn, thus causes potential safety hazard.And the setting of chamfering here can when electric wire bending, there is a relatively large contact area to it, thus just little to the pressure of electric wire, make the possibility that it is worn.
The utility model is set to further: described leg and terminal block housings one-body molded.
By adopting technique scheme, the position that leg and terminal block housings can be made to have a common boundary is more firm, and compare welding or other mode, the structural strength of whole terminal block housings is more outstanding.Serve the effect of reinforcement to a certain extent.
The utility model is set to further: described leg height 10mm-20mm, the thick 1mm-5mm of described leg.
By adopting technique scheme, show that the height of leg is between 10mm-20mm by concrete experiment, when thickness is between 1mm-5mm, namely the integral layout of junction box is not affected, can make again electric wire that a larger contact area can be had to contact with terminal block housings, be not easy wearing and tearing.Further, such setting can play good structural booster action.
The utility model is set to further: the inside of described terminal box is also provided with boss, and described boss is arranged on the angle of terminal box.
By adopting technique scheme, the angle of junction box is also provided with boss, the structural strength that this boss can make terminal box entirety is more strong, can avoid the collision of terminal box in transportation and damage, further can increase the useful life of terminal box.
Accompanying drawing explanation
Fig. 1 is the structure chart of the utility model terminal box embodiment.
In figure: 1, terminal block housings; 2, connector cover; 3, wiring hole; 4, leg; 5, chamfering; 6, boss.
Embodiment
With reference to Fig. 1, the utility model terminal box embodiment is described further.
A kind of terminal box as shown in Figure 1, comprise terminal block housings 1 and connector cover 2, here terminal block housings 1 offers wiring hole 3, and terminal block housings 1 inside here is also provided with leg 4, and leg 4 solderless wrapped connection string holes 3 edge is here fixed on terminal block housings 1.The setting of leg 4; the length of wiring hole 3 can be increased to a certain extent; such electric wire is when passing from wiring hole 3 when electric wire; larger contact area can be had with wiring hole 3, which increase contact area, reduce pressure; thus electric wire is served to the effect of protection; add useful life, be not easy the epidermis of electric wire to gall, more there is safety guarantee.Leg 4 offers chamfering 5 away from wiring hole 3 and with one end of line contacts in the present embodiment, and wiring hole 3 offers chamfering 5 towards one end of terminal block housings 1 outside.Like this be arranged on electric wire through after wiring hole 3, can produce the phenomenon of bending unavoidably, and this bending can there is a friction with the edge of wiring hole 3, so just creates certain impact to the life-span of electric wire, electric wire is easily worn, thus causes potential safety hazard.And the setting of chamfering 5 here can when electric wire bending, there is a relatively large contact area to it, thus just little to the pressure of electric wire, make the possibility that it is worn.In the present embodiment, leg 4 is one-body molded with terminal block housings 1.Here be only a kind of preferred embodiment, leg 4 also for stick in terminal block housings 1 by glue, also can be bolted with housing.The position that integrated set-up mode can make leg 4 and terminal block housings 1 have a common boundary is more firm, and compare welding or other mode, the structural strength of whole terminal block housings 1 is more outstanding.Serve the effect of reinforcement to a certain extent.In the present embodiment, the high 15mm of leg 4, the thick 4mm of described leg 4.Drawn by a large amount of experimental datas, namely such set-up mode does not affect the integral layout of junction box, can make again electric wire that a larger contact area can be had to contact with terminal block housings 1, be not easy wearing and tearing.Further, such setting can play good structural booster action.In the present embodiment, the inside of terminal box is also provided with boss 6, and described boss 6 is arranged on the angle of terminal box.The structural strength that this boss 6 can make terminal box entirety is more strong, can avoid the collision of terminal box in transportation and damage, further can increase the useful life of terminal box.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
