Embodiment

As shown in Figure 1, wedge shape strain clamp of the present invention, it comprises that mainly half fixture block 2a, the 2b of half lid 1a, the 1b of two correspondences, two correspondences and a pull bar 3 form, wherein:

Two and half lid 1a, 1b, form one group of outer cover (as shown in Figures 2 and 3) for coupling, two halves lid 1a, 1b all are provided with the one or more buckle 11a of portion, 11b and

buckle groove

12a, 12b in opposing sidewalls, and all offer a

groove

13a, 13b at the side wall, as shown in the figure, described

buckle groove

12a, 12b all position are located at a

wall extension

14a, 14b, and in fact described two and half lid 1a, 1b can be identical corresponding structure, so can make with same mould;

Half fixture block

2a, 2b form one group of internal clamping block for coupling, and to be suitable for that lead 4 wrapped folders are fixed (as shown in Figure 8), two

halves fixture block

2a, 2b also can be provided with relative protuberance 21a and recess 21b on the corresponding sides wall again;

One pull bar 3, it is a U-shaped body of rod, its two ends all have a pier nose 31, this pier nose is big step shape, so that the block effect to be provided, and all is nested with a packing ring 32 in advance at body of rod two ends, as shown in Figure 4, described pier nose 31 was inserted in the two ends body of rod with packing ring 32 in advance before moulding, reshaping is one to be the pier nose 31 (as the signal state of Fig. 5) of big step shape;

According to above-mentioned member, form one group of outer cover and internal clamping block by two and half lid 1a, 1b and two and

half fixture block

2a, 2b coupling, and internal clamping block is placed in the outer cover, the both sides body of rod of pull bar 3 is run through both sides groove 13a, the 13b that is cross-placed on outer cover, utilize the coupling of the 11a of buckle portion, 11b and

buckle groove

12a, 12b to fasten again, can finish the composition of strain insulator device.

The packing ring 32 of above-mentioned pull bar 3 is for the joint front end (as Fig. 3) that is limited to two halves lid 1a, 1b, so that the preferable effect that supports to be provided.

As shown in the figure, the 11a of buckle portion, the 11b of above-mentioned half lid 1a, 1b, therefore its inboard can be made as an inclined-plane 111a, 111b, can overturn quickly and easily and takes advantage of a situation and buckle into
