Specifically, the first gap 23 is located between the ring washer and the first connector 22 on the first fastener 21.

Optionally, the longitudinal section of the first main body is arc, and arc is raised towards the first gap 23, so that first Connector 22 is more easier deformation, to promote sensitivity.

In a kind of feasible pattern of the present embodiment, the second connector 32 includes the second main body and cathode construction 321, and second is main Body has the second cavity, and cathode construction 321 is movably disposed in the second main body, and the second main body is supported by the second fastener 31 Deformation is generated when clamp force, and pressure increase in the second cavity is made to release cathode construction 321.

Optionally, inert gas is filled in the second cavity, inert gas both can be used as medium, in the second connector 32 Pressure change is generated when deformation and cathode construction 321 is pushed to move, and can have good insulating properties, and then guarantees safety Property.

In the present embodiment another kind feasible pattern, the second connector 22 includes the second main body and cathode construction 321, cathode Structure 321 is fixed in the second main body, and mobile with the second main body in the second construction deformation.

For example, being contacted with the movement of the second main body with the first connector 22 when the second main body is by power stretching, extension is pushed against.

Optionally, be provided on cathode construction 321 accommodate contact pin jack, jack be used for contact pin cooperate, shape with Contact pin adaptation, it is for example round or rectangular etc..

Optionally, it is passed through for the ease of the second fastener 31, the second through-hole, the second fastener 31 is provided in the second main body Cooperate across the second through-hole, and with the second threaded hole on insulating base 10.

Optionally, in order to promote the reliability connecting with the second connector, between the second fastener 31 and the second connector 32 With the second gap 33 for accommodating the second connector.

Specifically, the second gap 33 is located between the ring washer and the second connector 32 on the second fastener 31.

Preferably, the second main body is arc, and arc is raised towards the second gap 33, so that the second connector 32 It is more easier deformation, to promote sensitivity.

In the present embodiment, when the height in the first connector space between the first fastener 21 and the first connector 22 is greater than First setting value, and/or, the height in the second connector space between the second fastener 31 and the second connector 32 is greater than second and sets When definite value, the first connector 22 and the second connector 32 are disengaged.

First main body is the arc-shaped conductive film structure with opening.Second main body is that the arc with opening is led Electric chip architecture.Since the first connector 22 and the second connector 32 are that opening zinc-plated the pressure-sensitive of steel tile structure of semicircular arc is led Therefore electric connecting sheet is put into the first gap 23 and in the first connector and the second connector (it can be U-shaped or pin type terminal) In two gaps 33, and when the first fastener 21 and the second fastener 31 tighten fixed, can more preferable stress and deformation generate pressure.

In conjunction with Fig. 2 and Fig. 3, connection terminal further includes insulation shell 40, what the first connector 22 and the second connector 32 contacted Part is embedded in insulation shell 40.Insulation shell 40 can play a supporting role to the first connector 22 and the second connector 32.

First connector 22 includes the first main body and anode construction 221, and anode construction 221 is connected in the first main body and is used in combination It is connected in contact；Second connector 32 includes the second main body and cathode construction 321, and cathode construction 321 is connected in the second main body And for contacting conducting with anode construction 221.Anode construction 221 and cathode construction 321 are respectively positioned in insulation shell 40, the first main body It is fixedly connected with insulation shell 40, the second main body is fixedly connected with insulation shell 40.Insulation shell 40 can support and limit anode construction 221 and cathode construction 321, and seal isolation both is provided and is reliably connected place.

Again since the first connector 22 and the second connector 32 are hollow and fill full inert gas (inert gas can be nitrogen Deng similar gas, there is fire prevention, arc extinction performance), therefore, the sun for the metal that the close terminal inner side edge of the first connector 22 is drawn The yin for the metal that pole structure 221 can be drawn in the insulation shell 40 that it is embedded with the close terminal inner side edge of the second connector 22 Pole structure 321 cooperates, and realizes contact or is detached from.

In the connection terminal use process, the first connector is inserted into the first gap 23, and the first fastener 21 passes through the first connection First through hole among part 22, is tightened with the nut 111 in pedestal 11, realizes fastening.First fastener 21 in rundown process, Stroke between ring washer thereon and the first connection 22 is decreased to contact, after there is the excess of stroke in contacting travel, the first connection Part 22 can generate miniature deformation, and internal pressure increases, and internal subtle pressure change reaction is filled with inert gas pressure Increase severely, the active force that internal pressure increases severely pushes anode construction 221 to elapse forward, with the cathode construction on the second connector 32 321 reliably contact, to guarantee to be connected.The course of work of second fastener 31 and the second connector 32 and the first fastener 21 Identical with the first connector 22, so it will not be repeated.

When the disappearance of the fastening excess of stroke of any first connector 22 and the first fastener 21, there is the first connector 22 or the second When the pressure release of connector 32, directly reflects terminal junction and loosen, at this time anode construction 221 or cathode construction The release of 321 pressure, occurs loosening the corresponding retraction in one end, can disconnect a little, avoid termination contact is bad from overheating.
