Detailed Description

The technical solution of the present invention will be described below with reference to the accompanying drawings of the embodiments of the present invention.

The first embodiment.

The improved structure of the electric connector electrode of the charging pile comprises a carrier, a first electrode 1 and a second electrode (not shown in the drawing) which are arranged on the carrier (not shown in the drawing and are generally made of ABS plastic and the like) and are in mutual contact conduction, and the improved structure further comprises an elastic insulator, wherein the elastic insulator is respectively abutted against or close to the first electrode 1 and the carrier, so that when the first electrode 1 is in contact with the second electrode, the first electrode 1 has elasticity.

Charging pile's electric connector electrode improves structure includes first electrode 1 and is provided with elastic insulator 2 of accommodation space 21. Generally, the elastic insulator 2 has an insulating property. Typically, the first electrode 1 is made of an electrically conductive material, such as brass or the like.

The first electrode 1 extends outwards to form a limiting body 14, the first electrode 1 is inserted into the accommodating space 21, and the limiting body 14 is exposed from the elastic insulator 2 (i.e. the contact end 19).

The elastic insulator 2 has elasticity. The elastic insulator 2 is made of rubber, for example. The elastic insulator 2 has a shore hardness of twenty degrees to eighty degrees, preferably, forty degrees.

The spacing body 14 has a portion which, viewed along the first electrode 1, extends beyond the receiving space 21.

The working principle is as follows: before use, the first electrode 1 is electrically connected to the wire W1.

When in use, the elastic insulator 2 is close to an object to be connected (not shown in the drawing, usually, the electrode of an electric connector of another charging pile is modified, and can also be a conductor electrically connected with the electric wire W1) until the contact end 19 is contacted with the object to be connected; the elastic insulator 2 is continuously moved, the first electrode 1 moves along the accommodating space 21, and the elastic insulator 2 is continuously moved until the limiting body 14 abuts against the elastic insulator 2 to enable the elastic insulator 2 to be elastically deformed; the position of the resilient insulator 2 is maintained (either by hand or by other conventional retention means such as snaps or the like). The elastic force provided by the elastic insulator 2 can ensure that the contact end 19 is tightly attached to the object to be connected, thereby ensuring the reliability of the electrical connection.

Preferably, the first electrode 1 is attached to the inner wall of the accommodating space 21; to ensure that the first electrode 1 does not wobble within the receiving space 21.

Preferably, the cross section of the first electrode 1 and the cross section of the elastic insulator 2 are both circular, and the cross section of the limiting body 14 is annular.

Further, the first electrode 1 is provided with a wiring hole 12, the other end of the first electrode 1 (i.e. the other end of the contact end 19) is provided with a holding hole 13 communicated with the wiring hole 12, and the holding hole 13 includes a threaded section 131. The first electrode 1 and the wire W1 are electrically connected by inserting the wire W1 into the wire connection hole 12, and then screwing a bolt (not shown) into the threaded section 131 to abut against the wire W1, so that the first electrode 1 and the wire W1 are electrically connected.

Furthermore, the side wall of the elastic insulator 2 is provided with a threading hole 22 communicated with the accommodating space 21, and the threading hole 22 is opposite to the wiring hole 12, namely, the wiring hole 12 is completely positioned in the threading hole 22 when viewed along the wiring hole 12. After the wire W1 is inserted into the wire connecting hole 12 through the threading hole 22, the wire W1 can be fixed to the first electrode 1, and the wire W1 is not clamped by the first electrode 1 and the inner wall of the accommodating space 21 and is not easy to move, so that the risk of the wire W1 falling off from the first electrode 1 can be eliminated or reduced.

Typically, the fixed segment 132 is formed for a fabrication aperture. The bolt abuts against the electric wire W1, bends the electric wire W1, and inserts the electric wire W1 into the fixing segment 132, thereby improving the connection strength between the first electrode 1 and the electric wire W1.

Preferably, the cross section of the first electrode 1 is non-circular (the cross section of the first electrode 1 is non-circular, and the drawing is not shown); such as rectangular, square, oval, etc., other than circular. The first electrode 1 can be prevented from rotating in the accommodating space 21, so that the inner wall of the threading hole 22 does not abut against the wire W1, and the risk that the wire W1 falls off from the first electrode 1 can be eliminated or reduced.

Preferably, the wiring holes 12 penetrate the first electrode 1, and the number of the threading holes 22 is two. The input portion 41 enables wiring through the wiring hole 12, further reducing the risk of the electric wire W1 falling off from the first electrode 1.
