Further, described wire clamp also comprises the first Compress Spring, and described the first Compress Spring bullet peaks between electroconductive elastic sheet and corresponding the first clamping limb or the second clamping limb;

Further, described electroconductive elastic sheet comprises shell fragment pedestal and embeds the fixing neonychium of described shell fragment pedestal;

Further, described neonychium has conductivity;

Further, described neonychium protrudes from described shell fragment pedestal;

Further, described the first clamping limb and the second clamping limb are provided with the Handheld Division of holding for pinching; The Handheld Division of described the first clamping limb is connected with the Handheld Division of described the second clamping limb by the second Compress Spring;

Further, the Handheld Division of described the first clamping limb and the second clamping limb is equipped with insulating case;

Further, end, described fixed arm Handheld Division is provided with conductor interface, and described the first end, clamping limb Handheld Division is provided with conductor interface, and described conductor interface is by described the first clamping limb and described electroconductive elastic sheet conducting.

The beneficial effects of the utility model are: wire clamp of the present utility model, on the clamping face of wire clamp, be provided with electroconductive elastic sheet, and this structure can make wire clamp fully contact with the terminals of equipment under test, has guaranteed the reliability that tester, instrument are connected with equipment under test; Meanwhile, described electroconductive elastic sheet place is provided with neonychium, with this, has avoided wire clamp to cause mechanical damage to testing equipment terminals.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further described:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is A-A cutaway view in Fig. 1.

Embodiment

Fig. 1 is structural representation of the present utility model, and Fig. 2 is the cutaway view at A place in Fig. 1, and as shown in the figure, wire clamp in the present embodiment, comprises the first clamping limb 1 and the second clamping limb 2; Described the first clamping limb 1 is articulated with the second clamping limb 2 and forms the clamp structure that can clamp object; The clamping face of described the first clamping limb 1 and/or the second clamping limb 2 is provided with electroconductive elastic sheet 3.

In the present embodiment, described wire clamp also comprises the first Compress Spring, described the first Compress Spring bullet peaks between electroconductive elastic sheet 3 and corresponding the first clamping limb 1 or the second clamping limb 2, this structure guarantees that electroconductive elastic sheet 3 can fully contact with equipment under test terminals, meanwhile, avoid wire clamp to come off from equipment under test terminals.

In the present embodiment, described electroconductive elastic sheet comprises shell fragment pedestal 6 and the fixing neonychium 7 of the described shell fragment pedestal 6 of embedding, and neonychium 7 is positioned at the clamp port inner side of clamp structure; Shell fragment pedestal 6 can be made by the good metal material of pliability; while guaranteeing wire clamp clamping, electroconductive elastic sheet 3 can contact the terminals of equipment under test preferably, and neonychium is made by flexible material; while avoiding wire clamp clamping equipment under test, equipment under test terminals are caused to mechanical damage.

In the present embodiment, described neonychium 7 has conductivity, guarantee neonychium 7 can with the conducting of shell fragment pedestal.

In the present embodiment, described neonychium 7 protrudes from described shell fragment pedestal 6, and neonychium 7 protrudes to the clamp port inner side of clamp structure, guarantees that equipment under test terminals can first contact with neonychium 7, thereby avoids equipment under test terminals to cause mechanical damage.

In the present embodiment, described the first clamping limb 1 and the second clamping limb 2 are provided with the Handheld Division 4 of holding for pinching; The Handheld Division of described the first clamping limb 1 is connected with the Handheld Division of described the second clamping limb 2 by the second Compress Spring, now, the resilience force that compression spring produces forces the clamping part of wire clamp the first clamping limb 1 and the second clamping limb 2 to produce the trend clamping, thereby guarantee that wire clamp can reliably clamp equipment under test terminals, avoid wire clamp landing.
