Embodiment 1

[0076] Such as image 3 As shown, the present invention provides a tension clamp housing 10, which includes a housing body 11, and a fixing cavity 12 is formed around the housing body 11, and the fixing cavity 12 is used to accommodate the left clamp of the tension clamp 1 core (not shown in the figure) and right sandwich core (not shown in the figure). Two bosses 111 are arranged on the outer surface of the shell body 11 , and both bosses 111 have through holes 112 , and the axial directions of the two through holes 112 coincide with each other. Wherein, any one of the bosses 111 has a receiving space 113 on the side facing the other boss 111 , and each receiving space 113 communicates with the through hole 112 of the adjacent boss 111 . The accommodating space 113 communicates with the outside of the shell body 11 and is located outside the fixing cavity 12 .

[0077] The two bosses 111 of the tension clamp housing 10 are provided with an accommodating space 113 outside th...

Embodiment 2

[0084] Such as Figure 4 As shown, the present invention also provides a tension clamp 1, which includes the tension clamp housing 10 as described in Embodiment 1, the tension clamp 1 also includes a pull rod 50, and the two pull rods 50 The connecting ends 51 are respectively arranged in the two accommodation spaces 113 of the tension clamp housing 10, and the two connecting ends 51 both have extensions 511, and the two extensions 511 pass through through holes adjacent to the accommodation spaces 113 112 inside. In the tension clamp 1 , both connecting ends 51 of the pull rod 50 have extensions 511 for passing through the through hole 112 of the tension clamp housing 10 . When installing the extensions 511 of the pull rod 50 into the two through holes 112, the two connecting ends 51 should be pressed first to reduce the distance between the two extensions 511 and make the two extensions 511 The distance is also relatively close, and then the two extensions 511 and the corr...

Embodiment 3

[0091] Such as image 3 with Image 6 As shown, the present invention also provides a tension clamp 1, which includes the tension clamp housing 10 as described in Embodiment 1, the tension clamp 1 also includes a hanging plate 60, the hanging plate 60 The two connecting ends 61 are respectively attached to the sides of the two bosses 111 of the strain clamp housing 10 facing away from the accommodation space 113 , and are movably connected to the through holes 112 in the two bosses 111 .

[0092]In the tension clamp 1, the two connecting ends 61 of the hanging plate 60 are arranged on the side of the boss 111 away from the accommodating space 113, and are movably connected with the through hole 112 of the boss 111, so that the tension wire The tension clamp housing 10 of the clamp 1 can not only be connected to the tie rod 50 to form the tie rod type tension clamp 1 , but also can be connected to the hanging plate 60 to form the hanging plate type tension clamp 1 .

Abstract

The invention discloses a strain clamp housing and a strain clamp having the same. The strain clamp housing comprises a housing body, wherein the housing body forms a fixed cavity; the outer surface of the housing body are provided with two bosses; each of the two bosses has a through hole; the axes of the two through holes coincide with each other; either of the bosses has a receiving space at aside toward the other boss; each receiving space communicates with the through hole of the adjacent boss and communicates with the outer side of the housing body; and the receiving spaces are locatedoutside the fixed cavity. By means of the receiving spaces between the two bosses of the strain clamp housing and outside the fixed cavity, the strain clamp housing can be connected to the outer sideof a hanging plate through the outer sides of the bosses, and can also be connected to a pull rod via the through holes on the bosses and the receiving spaces. Thus, the strain clamp housing can be simultaneously used for a pull-rod strain clamp or a hanging-plate strain clamp, thereby being universal.

Description

technical field [0001] The invention relates to a tension clamp shell and a tension clamp containing the same. Background technique [0002] With the rapid development of power application facilities in power distribution networks, in the overhead power system with a rated voltage of 10kv and below, insulated strain clamps are required to anchor and tighten both ends of insulated overhead cables to poles or towers . [0003] Such as figure 1 with figure 2 As shown, the tension clamp used in the prior art includes a tension clamp housing 10', a left sandwich core 20' and a right sandwich core 30', the shell body 11 of the tension clamp housing 10' ' is surrounded by a fixed cavity (not shown in the figure), which is wedge-shaped. (not shown in ), to cooperate to form a clamping groove capable of clamping and fixing the cable. [0004] The suspension form of the strain clamp includes two structures of a pull rod type and a hanging plate type. Such as figure 1 As shown,...
