23 separate, and are convenient for the plug of electric wire 4, easy to operate.
In the present embodiment, the operating element 3 is made of insulating materials.
As shown in Fig. 2, the left clamp arm 22 is vertical including left-leaning oblique arm 221, left interconnecting piece 222 and the left side being sequentially connected
The outer end of plate 223, the "Left"-deviationist oblique arm 221 is connected with one end of the bottom plate 21, and the arc cantilever plate 224 is arranged in institute
On the end for stating left vertical plate 223, the clamp arm 22 can be kept out on the peripheral surface of the electric wire 4.
It suppresses arm 225 as shown in Fig. 2, the left clamp arm 22 further includes a left side and stretches pressure head 226, arm 225 is suppressed on the left side
It is connected on the medial surface of the left vertical plate 223, and the left side is suppressed the free end of arm 225 and extended to the bottom plate 21, institute
State a left side and suppress and form left contraction chamber 227 between arm 225 and the left vertical plate 223, it is described stretch the inclination of pressure head 226 be mutually connected in it is described
A left side is suppressed on the free end of arm 225, and the root of arm 225 is suppressed in the end and the left side of the free end for stretching pressure head 226
It keeps out on the peripheral surface of the electric wire 4, as shown in figure 4, when arm 225 is suppressed on the end for the free end for stretching pressure head 226 and a left side
Root is kept out when on the peripheral surface of the electric wire 4, and a left side can be made to suppress arm 225 and stretch pressure head under the squeezing action of electric wire 4
226 to the left vertical plate 223 it is close so that left contraction chamber 227 becomes smaller, and realizes Multi-contact, and the left bullet using the above structure
The deformation of pressure arm 225 can apply certain pressure on the electric wire 4, and the electric wire 4 is made to be connect with the clamping unit 2 reliably.
As shown in Fig. 2, the right clamp arm 23 is vertical including Right deviation oblique arm 231, right interconnecting piece 232 and the right side being sequentially connected
The free end of plate 233, the Right deviation oblique arm 231 is connected with the other end of the bottom plate 21, is located at the outer of the right clamp arm 23
Hanging plate 236 and the inner wall of the inner cavity chamber 11 on side are fixed together, and the hanging plate 236 is kept out outside the insulation
On the step 14 of shell 1, the medial surface of the right vertical plate 233 can be kept out on the peripheral surface of the electric wire 4.
As shown in Fig. 2, the right clamp arm 23, which further includes the right side, suppresses arm 234, the right side suppress arm 234 be fixedly connected on
On the medial surface of the right vertical plate 233, the free end that arm 234 is suppressed on the right side extends to the bottom plate 21, and the right side is suppressed
Arm 234 and the left side form an opening 25 between suppressing arm 225, and shape between arm 234 and the right vertical plate 233 is suppressed on the right side
At right contraction chamber 235, the medial surface that arm 234 is suppressed on the right side can be kept out on the peripheral surface of the electric wire 4, increase the right folder
The contact area of tight arm 23 and electric wire 4, that is, increase the frictional force between the right clamp arm 23 and electric wire 4, reduces electric wire 4 and falls off
Probability, as shown in figure 4, when the right side is suppressed the medial surface of arm 234 and kept out on the peripheral surface of the electric wire 4, in squeezing for electric wire 4
It can to suppress arm 234 in the right side that vertical plate 233 is close to the right under pressure effect so that right contraction chamber 235 becomes smaller.
As shown in Fig. 2, the clamping unit 2 further includes a pair of of bow shrapnel 24, a pair of bow shrapnel 24 is separately positioned on described
On the medial surface of the medial surface of left-leaning oblique arm 221 and the Right deviation oblique arm 231, a pair of bow shrapnel 24 can play the work of auxiliary clamp
With so that the free end of electric wire 4 is relatively reliablely clamped, and the electric wire 4 is made to be contacted with the bottom plate 21 reliably.
As shown in Fig. 2, the bow shrapnel 24 includes fixed plate 241, transition part 242 and the hanging deck 243 being sequentially connected, it is a pair of
Fixed plate 241 is inclined at the medial surface of the medial surface and the Right deviation oblique arm 231 of the left-leaning oblique arm 221 respectively inwards
On, the hanging deck 243 is vacantly arranged, and the electric wire 4 can be clamped in the lateral surface of a pair of of transition part 242, the hanging deck 243
Free end have and touch slippery fellow 2431, described tactile foxy 2431 can be made to be resisted against the left-leaning oblique arm 221 under the action of electric wire 4
Medial surface and the Right deviation oblique arm 231 medial surface on, make the bow bullet when described tactile foxy 2431 move along medial surface
Piece 24 increases the elastic force of the bow shrapnel 24 when being unfolded, so that the electric wire 4 is contacted reliably with bow shrapnel 24, avoid oneself of electric wire 4
It is bent by end and causes poor contact.
As shown in Figure 3 and Figure 4, it is intended to electric wire 4 being inserted into inner cavity chamber 11, when clamping unit 2 being made to be clamped it, first
Operator should press operating element 3 downwards so that right clamp arm 23 opens, and electric wire 4 is made more successfully to pass through insulation crust 1
On entrance hole 12 enter in inner cavity chamber 11, when the end of the electric wire 4 and the bottom plate 21 contact, it is first to unclamp the operation
Part 3, the left clamp arm 22 reset, and make left clamp arm 22 and right clamp arm 23 that the middle part of electric wire 4 can be clamped, a pair of bow
The free end of electric wire 4 can be clamped in shrapnel 24 so that electric wire 4 is so clamped that more to fasten, and the bottom end of electric wire 4 and bottom plate
21 top surface is reliably bonded, meanwhile, operating element 3 moves up under the impetus of the arc cantilever plate 224.
Easy to operate, good clamping effect of the invention, it is at low cost.
It these are only the preferred embodiment of the present invention, be not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.Any modification made by all within the spirits and principles of the present invention,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
