Preferably, described raised line is the stripe shape raised line, and described stripe shape is symmetric form or dislocation type.

Preferably, described raised line is S type raised line, fold-type raised line or undaform raised line.

Preferably, described raised line is twill raised line or grid type raised line.

Preferably, the cross section of described wire casing is a V-type.

Preferably, be provided with boss face, below described boss face, be connected with the V-type cross section at the port of described wire casing.

Pass through technique scheme, the beneficial effects of the utility model are: be provided with raised line in the wire casing inner wall surface, increased frictional force to cable, while is provided with raised line to the ply-yarn drill that cable plays fixation, increased the friction area that is subjected to of cable, thereby avoided causing binding post to get loose because of cable slides.

Embodiment

In order further to understand the utility model, below in conjunction with the accompanying drawing among the utility model embodiment, preferred embodiment in the present embodiment is described, but be to be understood that, these are described just to further specifying feature and advantage of the present utility model, rather than to the restriction of the utility model claim.

Embodiment 1,

As shown in Figure 1, a kind of terminal box comprises box body 1 and wire casing 2, also comprise the ply-yarn drill that cable is played fixation, wire casing 2 is arranged at the two ends of box body 1, and ply-yarn drill is fixedly connected on the wire casing 2 with screw, and face corresponding with wire casing 2 on the inner wall surface of wire casing 2 and/or the ply-yarn drill is provided with raised line.Be provided with raised line in wire casing 2 inner wall surface, increase the frictional force to cable, ply-yarn drill is provided with raised line simultaneously, has also increased the area that cable is rubbed when cable is fixed, thereby has avoided causing getting loose of binding post because of cable slides.

As shown in Figure 2, the stripe shape raised line that is provided with in the wire casing 2 is a symmetric form raised line 21, can increase the frictional force of cable, this stripe shape raised line also can be dislocation type raised line 22 simultaneously, as shown in Figure 3, because this raised line arrangement is asymmetric, can increase the area that cable is rubbed, thereby strengthen frictional force.

Embodiment 2,

As shown in Figure 4, all the other are identical with embodiment 1, and difference is, is provided with the raised line with regular shape in the wire casing 2, and this raised line is a S type raised line 23, also can be fold-type raised line 24 (as shown in Figure 5), can also be undaform raised line 25 (as shown in Figure 6); Be provided with the raised line of regular shape in the inner wall surface of wire casing 2, can effectively increase the friction area that is subjected to of cable.

Embodiment 3,

As shown in Figure 7, all the other are identical with embodiment 1, difference is, be provided with twill raised line 26 in the wire casing 2, this raised line also can be the raised line 27 (as shown in Figure 8) of grid type, is provided with raised line in wire casing 2 inner wall surface, increases the frictional force to cable, thereby avoid cable to slide, cause getting loose of binding post.

Embodiment 4,

As shown in Figure 9, all the other are identical with embodiment 1, and difference is that the cross section of wire casing 2 is a V-type, when cable is positioned in the wire casing, add a cover ply-yarn drill, the cable extruding is stuck between the V-type cross section 3, cable shrinks because of extruding, produces elastic-friction, thereby has increased the frictional force to cable.

Embodiment 5,

As shown in figure 10, all the other are identical with embodiment 1, and difference is that the port of wire casing 2 is provided with boss face 4, below boss face 4, be connected with V-type cross section 3, when cable is positioned in the wire casing, V-type cross section 3 extruding cables, 4 pairs of cables of boss face play the extruding fixation, increased the stiction between cable and the cross section, cable just can firmly be stuck between boss face 4 and the V-type cross section 3, can not slide easily, and cause getting loose of binding post.

Adopt the beneficial effect of technical solutions of the utility model to be: terminal box disclosed in the utility model, comprise box body 1 and wire casing 2, also comprise the ply-yarn drill that cable is played fixation, wire casing 2 is arranged at the two ends of box body 1, ply-yarn drill is fixedly connected on the wire casing 2 with screw, and face corresponding with wire casing 2 on the inner wall surface of wire casing 2 and/or the ply-yarn drill is provided with raised line; Be provided with raised line in wire casing 2 inner wall surface, increase is to the frictional force of cable, the face corresponding with wire casing is provided with raised line on ply-yarn drill simultaneously, also increased the area that cable is rubbed when cable is fixed, thereby avoided causing getting loose of binding post because of cable slides.

Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
