Abstract

No threaded connecting terminal with stronger clamp force, including the shell fragment arm that is used for pressing from both sides tight wire, no threaded connecting terminal on be equipped with the concave groove that holds and press from both sides tight wire. Owing to be equipped with the concave groove that is used for further holding and pressing from both sides tight wire on the no threaded connecting terminal, the wire is by tightlyer double -layered under the effect of concave groove, especially to stranded conductor, because consequently the existence of concave groove has sufficient clamp force and press from both sides tight stranded wire to make no threaded connecting terminal can connect the stranded wire.

Description

Have stronger clamping force without screw terminal

Technical field

The utility model relates to a kind of without screw terminal.

Background technology

Usually in electrical power wiring assembly (such as switch or wall socket), extensive use connects the wire be incorporated in base without screw terminal.This generally have shell fragment arm for clamping wire without screw terminal.But, this routine be merely able to connect single condctor without screw terminal, can not connect stranded conductor, its reason is that the clamping force of shell fragment arm pair twist zygonema is inadequate, can not meet instructions for use.

Summary of the invention

In order to overcome the existing above-mentioned deficiency without screw terminal, the utility model provide a kind of have stronger clamping force without screw terminal.

The technical scheme in the invention for solving the technical problem is: have stronger clamping force without screw terminal, comprise the shell fragment arm for clamping wire, described being provided with without screw terminal is held and the Baltimore groove of clamping wire.

A kind of specific constructive form without screw terminal is: described shell fragment arm comprises shell fragment upper arm, shell fragment underarm, the afterbody of described shell fragment upper arm and the afterbody of shell fragment underarm are connected by linking arm, and described Baltimore groove is located at the front end of shell fragment upper arm and the front end of shell fragment underarm.

Further, the front end of described shell fragment upper arm is plane, and the front end of described shell fragment underarm is plane, on the front plan that described Baltimore groove is located at shell fragment upper arm and on the front plan of shell fragment underarm.

Further, the front end of described shell fragment upper arm has the flap to inflection, and the front end of described shell fragment underarm is plane, and described Baltimore groove is located on the front plan of the intersection of the front end of shell fragment upper arm and flap, shell fragment underarm.

The another kind of specific constructive form without screw terminal is: described also comprises transfer arm without screw terminal, described transfer arm and described shell fragment arm integral, described transfer arm offers clamp window, in clamp window described in described shell fragment arm inserts, shell fragment arm described under the effect of elastic force is pushed against on the front end face of described clamp window, and described Baltimore groove is located on the front end face of described clamp window.

Further, described Baltimore groove is provided with several on the front end face of described clamp window, thus Baltimore groove is linked to be groove tooth.

Further, described Baltimore groove is V-shaped.

The utility model is in use, the same without screw terminal with existing, by shell fragment arm by conductor clamping.

The beneficial effects of the utility model are: owing to being provided with for holding further and the Baltimore groove of clamping wire without screw terminal, wire is held tighter under the effect of Baltimore groove, especially for stranded conductor, due to the existence of Baltimore groove, therefore there is enough clamping forces to clamp twisted wire, thus enable to connect twisted wire without screw terminal.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Embodiment one

With reference to Fig. 1, Fig. 2, Fig. 3, have stronger clamping force without screw terminal, comprise the shell fragment arm for clamping wire, described shell fragment arm comprises shell fragment upper arm 1, shell fragment underarm 2, the afterbody of described shell fragment upper arm 1 and the afterbody of shell fragment underarm 2 are connected by linking arm 3, and the front end of described shell fragment upper arm 1 and the front end of shell fragment underarm 2 are provided with Baltimore groove 4.The present embodiment middle concave groove 4 is V-shaped, certainly also can adopt other shapes.

A kind of without screw terminal concrete, the front end of described shell fragment upper arm 1 can be plane, and the front end of described shell fragment underarm 2 can be plane as shown in Figure 2, on the front plan that described Baltimore groove 4 is located at shell fragment upper arm 1 and on the front plan of shell fragment underarm 2.

Another kind of without screw terminal specifically as shown in Figure 3, the front end of described shell fragment upper arm 1 can have the flap 5 to inflection, the front end of described shell fragment underarm 2 is plane, and described Baltimore groove 4 is located on the front plan of the intersection of the front end of shell fragment upper arm 1 and flap 5, shell fragment underarm 2.

When wiring, load in pedestal 6 without screw terminal, shell fragment upper arm 1 is promoted and shell fragment underarm 2 is out of shape by operation slide block 7, thus wire 8 is inserted, releasing operation slide block 7 afterwards, in the presence of a tensile force shell fragment upper arm 1 and shell fragment underarm 2 resilience, by shell fragment upper arm 1 and shell fragment underarm 2 by conductor clamping, simultaneously wire 8 embeds in Baltimore groove 4, can clamping wire further.

Embodiment two

With reference to Fig. 4, Fig. 5, Fig. 6, Fig. 7, have stronger clamping force without screw terminal, comprise the shell fragment arm 9 for clamping wire, described also comprises transfer arm 10 without screw terminal, described transfer arm 10 is integral with described shell fragment arm 9, described transfer arm 10 offers clamp window 11, described shell fragment arm 9 inserts in described clamp window 11, shell fragment arm 9 described under elastic acting force is pushed against on the front end face of described clamp window 11, and the front end face of described clamp window 11 is provided with Baltimore groove 4.Baltimore groove 4 described in the present embodiment is V-shaped, certainly may also be other shapes, and described Baltimore groove 4 is provided with several on the front end face of described clamp window 11, thus Baltimore groove is linked to be groove tooth.

When wiring, load in pedestal without screw terminal, insert copper sheet 13 in pedestal, copper sheet 13 leans on mutually with shell fragment arm 9, and copper sheet 13 also inserts in clamp window 11.Stretched in pedestal by screwdriver and promote transfer arm 10, transfer arm 10 is out of shape, transfer arm 10 moves towards shell fragment arm 9 direction, afterwards wire 8 is inserted in clamp window 11, after unclamping screwdriver, transfer arm 10 resets in the presence of a tensile force, between front end face wire 8 being clamped in copper sheet 13 and clamp window 11.Because Baltimore groove 4 is linked to be groove tooth, can be held tighter at the effect lower wire of groove tooth.Certain Baltimore groove 4 also can not be linked to be groove tooth, and only establishes a Baltimore groove, now the same with embodiment one, and wire embeds in Baltimore groove, can clamping wire further.
