In addition, there are other situations, such as connection between a power supply side and two power consumption side devices, and when it is necessary to keep one power consumption side device connected to the power supply side and the other power consumption side device disconnected from the power supply side, there are many kinds of prior art, such as a disconnecting switch, etc., and for a power line, since it is often a high position, it is very difficult for a ground operator to operate, and thus, there is a need for an opening and closing wire clamp that can be operated from the ground.
SUMMERY OF THE UTILITY MODEL
In order to solve the above technical problems, an object of the present invention is to provide a wire clamp, which can be connected to and disconnected from another power-consuming side electrode by external force while ensuring that the power-supplying side electrode and one power-consuming side electrode are always connected; the specific technical scheme is as follows:
a pressure-driven opening and closing wire clamp comprises a base, wherein coaxial through holes are formed in two sides of the base, and a power supply side electrode and a power utilization side electrode are embedded into the through holes; a threaded through hole is formed above the base, threads are arranged on the outer side of the sliding seat, the sliding seat is screwed in the threaded through hole, and a slide way is arranged in the middle of the sliding seat; one end of the insertion block is a straight surface, the other end of the insertion block is an inclined surface, the surface of the power supply side electrode corresponding to the insertion block is a straight surface, and the surface of the power utilization side electrode corresponding to the insertion block is an inclined surface; the insertion block is arranged between the power supply side electrode and the power utilization side electrode; a sliding rod is arranged above the inserting block and inserted into the sliding way, and a spring is sleeved outside the sliding rod; and a force application hole is formed in the position, corresponding to the insertion block, below the base.
The inclined angle of the inclined plane is 45 degrees.
And a protective cover is arranged on the outer side of the wire clamp.
The base is cylindrical.
The axis of the force application hole is overlapped with the axis of the sliding rod.
The utility model has the advantages that: the connection and disconnection of the circuit are combined with the application of external force to the electrode on the other side, so that the connection and disconnection of the circuit can be ensured by the action of the external force. When the lightning arrester is used for lightning protection, the lightning arrester can be disconnected from the electricity utilization side through the action of the upper binding post of the lightning arrester. The swing arm on the telegraph pole cross arm can be operated through the long rod by a person on the ground to realize connection and disconnection of the circuit.

Detailed Description
The present invention is described in detail below with reference to the accompanying drawings, and as shown in the drawings, the present invention includes a base 1, coaxial through holes are provided on both sides of the base 1, and a power supply side electrode 2 and a power utilization side electrode 3 are both embedded in the through holes; a threaded through hole 7 is formed above the base, threads are formed on the outer side of the sliding seat 6, the sliding seat 6 is screwed in the threaded through hole 7, and a slide way 8 is arranged in the middle of the sliding seat 6; one end of the plug-in block 4 is a straight surface, the other end is an inclined surface, the surface of the power supply side electrode corresponding to the plug-in block is a straight surface 21, and the surface of the power utilization side electrode corresponding to the plug-in block is an inclined surface 31; the insertion block 4 is provided between the power supply side electrode 2 and the power consumption side electrode 3; a sliding rod 5 is fixedly arranged above the insertion block, the sliding rod 5 is inserted into the slideway 8, and a spring 9 is sleeved outside the sliding rod 5; and a force application hole 10 is formed in the position, corresponding to the insertion block, below the base.
The inclined angle of the inclined plane is 45 degrees.
And a protective cover 11 is arranged on the outer side of the wire clamp.
The base is cylindrical.
The axis of the force application hole is overlapped with the axis of the sliding rod.
As shown in fig. 4, when the cable clamp of the present invention is used in an arrester circuit, a stopper 13 made of low temperature melting alloy is arranged in the arrester housing 12, a baffle 15 is arranged below the stopper 13, a pop-up spring 14 and a zinc oxide resistance card 18 are arranged below the baffle 15, an upper terminal 16 is fixed above the baffle 15, the lower part of the zinc oxide resistance card 18 is connected with a lower electrode 17, and the elasticity of the pop-up spring is far greater than that of the spring 9; when lightning strike occurs, the current melts the stop block 13, the baffle plate 15 is upwards popped out under the action of the pop-up spring to drive the upper wiring terminal 16 to upwards move, and further the insertion block 4 is pressed to upwards move, and the insertion block is always kept connected with the power supply side electrode because the contact surface of the insertion block and the power supply side electrode is a straight surface, and the contact surface of the insertion block and the power utilization side electrode is an inclined surface, so that the insertion block rises to cause the disconnection of the insertion block and the power utilization side electrode, and thus, the lightning strike current is conducted with the grounding terminal through the lightning arrester, and meanwhile, the connection with the power utilization terminal is disconnected. The utility model discloses a fastener can also operate the swing arm on the wire pole cross arm through the stock through the personnel on ground and realize the switch-on and the disconnection of circuit.
