In the present embodiment, described wire clamp 16 comprises the left arm 18 and right arm 19 that are hinged on main hinged shaft 17 both sides, main hinged shaft is wound with elasticity and pushes the operating side of left arm and right arm open and the main torsion spring 20 that its bare terminal end is pressed together, left arm, right arm, main hinged shaft and the flexible insulating gum cover 21 of main torsion spring paste outside, left arm and right arm clamping part are evenly equipped with the corresponding clip tooth 22 arranged, insulating gum cover is provided with the clip tooth hole 23 corresponding with clip tooth, the insulating gum cover of left arm and right arm clamping part periphery is sealedly connected with the elastic insulated glue lip 24 extended in opposite directions, the insulating cement lip avris of left arm is provided with the lip groove 25 of oral area towards right arm insulating cement lip, the insulating cement lip avris of right arm be provided with extend in lip groove and with the lip plug 26 of lip trench bottom elastic compression.
This wire clamp has inner clip and holds the dual clamp structure forming electrical connection, outer clamping formation sealed insulation, respectively referred to as interior clamp structure and outer clamp structure.Wherein interior clamp structure mainly comprises the left arm and right arm that are hinged on main hinged shaft both sides, and is wrapped on main hinged shaft and makes the main torsion spring of left arm together with right arm clamping part elastic compression.Because left arm, right arm, main hinged shaft and main torsion spring are all have electric conducting material to make, therefore when left arm and right arm clamping part clamp electric wire, the probe of detecting instrument or terminal, wire clamp will form with them and is electrically connected.Because left arm and right arm are by together with main torsion spring elastic compression, and the clamping part of left arm and right arm being evenly equipped with the corresponding clip tooth arranged, therefore can ensureing the reliability be electrically connected when clamping electric wire, the probe of detecting instrument or terminal.For convenience of describing, by left arm and the softened state of right arm clamping part, also be that the state that on left arm, clip tooth is separated with clip tooth on right arm is called clamp position or softened state, by the state that left arm and right arm clamping part are clamped together, the state that also namely on clip tooth and right arm, clip tooth is clamped together on left arm is called nature or closure state.
Outer clamp structure mainly comprises the insulating gum cover being wrapped in left arm, right arm, main hinged shaft and main torsion spring outside, and insulating gum cover has elasticity, tightly can be wrapped on left arm and right arm periphery, therefore can not affect the holding action of left arm and right arm.The insulating gum cover of left arm and right arm clamping part is provided with clip tooth hole, clamping one_to_one corresponding on clip tooth hole and left arm and right arm, therefore when left arm and right arm clamping part clamping external current conductor, except clamping can form with it except electrical connection, this wire clamp any part all insulate with it because of the insulating effect of insulating gum cover, greatly strengthen the fail safe of operation.The insulating gum cover of left arm and right arm clamping part periphery is installed with the insulating cement lip extended in opposite directions, also namely left arm clamping part periphery is sealed with the insulating cement lip extended to right arm clamping part, and right arm clamping part periphery is also sealedly connected with the insulating cement lip extended to left arm clamping part, the insulating cement lip on left arm and the insulating cement lip on right arm are arranged in opposite directions.Like this, just many again layer insulatings outside the clip tooth of left arm and right arm clamping part, i.e. insulating cement lip, serves and blocks effect to clip tooth, can avoid the electric conductor that other electric conductors outside touch clip tooth or clamped when clip tooth clamping external current conductor.The insulating cement lip edge of left arm is provided with lip groove, and lip notch is arranged towards right arm insulating cement lip.The insulating cement lip edge of right arm is provided with lip plug, and when left arm and right arm clamping part are in closure state, lip plug automatically to extend in lip groove and coordinates with lip trench bottom elastic compression.Like this, left arm insulating cement lip and right arm insulating cement lip are just sealed connected together by the elasticity extruding of lip groove and lip plug, by the effect of clip tooth and exterior insulation when not only serving closure state, and the effect of wire clamp external waterproof when also serving closure state.That is, when not using wire clamp, wire clamp is in closure state, and now insulating cement lip, lip groove and lip plug make clip tooth and exterior insulation, waterproof, and substantially increasing originally can the dependability of electrical power wiring device of fast-wiring.
The cross section of inboard wall of described lip groove is V-shaped, and the external wall cross-section of described lip plug is in the wedge shape matched with lip groove inwall.By V-shaped for the cross section of inboard wall of lip groove, the external wall cross-section of described lip plug is in the wedge shape matched with lip groove inwall, can make originally can the electrical power wiring device of fast-wiring when being changed to closure state by softened state, when being also mobile in lip plug labiad groove, the lip plug that wedge shape is arranged can automatic alignment lip plug, avoid lip plug, lip groove inconsistent phenomenon to occur, also namely improve originally can the sealing reliability of electrical power wiring device of fast-wiring, insulating reliability and functional reliability.
Lip plug both sides are respectively equipped with and the boss 27 of lip trough rim along compression fit.After lip plug both sides arrange boss, when closure state, also when namely lip plug is inserted in lip groove, the boss of lip plug both sides just in time touches lip trough rim edge, such boss and lip plug edge are just together with elastic compression, serve again the effect of airtight two insulating cement lips, make the insulating cement lip seal between left arm and right arm clamping part stronger.
Insulating gum cover outer wall corresponding to left arm and right arm articulated section is sealedly connected with and left arm and right arm clamping part is sleeved on interior elasticity external insulation gum cover 28.After arranging external insulation gum cover, because the insulating gum cover of external insulation gum cover one end and left arm and right arm articulated section is tightly connected, therefore external insulation gum cover be exactly a bottom towards left arm and right arm operating side oral area towards the sleeve of its bare terminal end.Like this, just be equivalent to there is dielectric layers at left arm and right arm clamping part outside, namely be adjacent to the insulating cement jacket layer (comprising insulating cement lip) of setting and the external insulation gum cover layer of ring set outside, substantially increase the insulating properties of left arm and right arm clamping part, processing safety.When running into the larger binding clip of some volumes of clamping or instrument terminal, binding clip or the instrument terminal of conduction will inevitably expose insulating cement lip, the risk that the binding clip of so just existence conduction or instrument terminal contact with other conductive components outside.After external insulation gum cover is set, even if the binding clip of conduction or instrument terminal breach first time insulating barrier, originally can fast-wiring electrical power wiring device arrange external insulation gum cover also its ladle cover can be got up, so just completely cut off the passage that it contacts with external current conductor, greatly strengthen fail safe.
