Example 1:

the present embodiment discloses an in-socket conductive motion block for connecting a conductive sheet 7 and a pin provided in a socket having a waterproof structure.

Specifically, the socket specifically comprises a shell, a moving block and a conducting strip 7, wherein the moving block and the conducting strip 7 are arranged in the shell, the conducting strip 7 and the moving block are arranged in different areas, and a sliding rail or a limiting channel is arranged in the socket to limit the moving block to reciprocate only in a fixed direction.

Furthermore, the sealing element 2 is made of an insulating flexible material and has certain elasticity, and the sealing element 2 blocks the moving block from contacting the conducting strip 7 under the action of no external force. When the pins push the moving piece 1 to move, the moving piece 1 or the contact 3 pushes the sealing piece 2 to deform, resistance for blocking the moving piece 1 is formed due to the deformation of the sealing piece 2, and the sealing piece 2 pushes the moving piece back to reset when the moving piece 1 loses the pushing of the pins. The sealing element 2 is a horn-shaped structure sleeved on the contact 3, and the outer ring of the sealing element is provided with an annular flange clamped with the socket.

In some embodiments, as shown in fig. 8, which is the first way of providing the contacts 4 in this embodiment. Fig. 8 shows that the contact 4 is covered on the end face of the contact 3 contacting with the conducting strip 7, and the contact 4 is fixed on the surface of the contact 3 by welding or bonding and conducts electricity with the contact 3. Contact 4 is the lamellar body structure of thickness such as homogeneity, generally adopts the conducting material of being different with contact 3 to make, has better resistant electric corrosion's performance, compares in ordinary brass contact 3 structure, can reduce the size of electric arc through better electric conductivity in the contact process with conducting strip 7 repeatedly, reduces the temperature rise simultaneously, improves life.

Because the contact 4 and the contact 3 are of a split structure, the contact is arranged in a manner of covering the surface of the contact 3 through a manufacturing process, once the contact 4 is damaged, the original contact 4 layer can be directly removed, and then the end surface of the contact 3 covers a new contact 4 layer through the process, so that the maintenance cost is reduced.

In some embodiments, as a second mode, a sunken groove is formed in the end surface of the contact 3 contacting the conducting strip 7, and the separated contact 4 is arranged in the sunken groove.

In some embodiments, the contact 4 has an insertion end that protrudes into the sunken groove and an enlarged end that contacts the conductive strip 7, the enlarged end completely covering the end face of the contact 3 having the sunken groove; or the insertion end is in interference fit with the sinking groove; or the insertion end is in threaded fit with the sinking groove; or the insertion end is fixedly connected with the sinking groove through welding.

Further, the thickness of the contact 4 is 0.1-2.0mm.

The contact 3 has a cylindrical structure, and has a surface provided with a screw thread, and a locking member 5 for pressing the sealing member 2 against the moving member 1 is engaged with the screw thread.

The smaller end of the sealing element 2 is sleeved with the contact 3 and abuts against the surface of the disc, and in the embodiment, sealant can be arranged at the gap or the opening edge of the sealing element 2 is fixed on the surface of the contact 3 in a clamping groove mode to form fixed connection.

In some embodiments, the concave inner side of the sealing member 2 has a continuously expanding opening for receiving the locking member 5, and the locking member 5 has an internal thread on its inner side, and the sealing connection is formed by screwing the locking member 5 onto the contact 3 from the concave side of the sealing member 2, thereby pressing the end face of the sealing member 2 against the end face of the disc.

As can be seen in fig. 5, the discharge gun converter has similar parts to a common socket, and is a cable for connecting an external plug and an internal plug, and the cable of the discharge gun converter is a pin.

In the housing, there are two parts which snap into each other, namely an upper housing with a socket opening and a lower housing to which the socket is connected. The lower shell is internally provided with a plurality of communicated grooves for placing the fixed conducting strips 7 and the moving blocks. The sealing block 6 is arranged at the end part of the inner side of the socket opening, the sealing block 6 is covered with the end surface of the inner side of the socket opening, and a better sealing effect is provided by matching with the movable blocking block at the socket opening.

The conducting strip 7 in this embodiment is of a U-shaped strip construction, wherein the bend is intended to receive the end of a pin inserted therebelow, and on its right side is likewise provided with a removable pin, which is intended to be brought into contact with the contact 4 via the pin and is likewise replaceable.

In this embodiment, the moving member 1 and the contact 3 are integrally formed by brass, and the contact 4 is supported by silver, so that the heating and electric corrosion phenomena caused by the low conductivity of the brass in long-term use can be effectively reduced by the structure of the contact 4 with the insertion type, and the service life of the contact is prolonged.

However, since the thickness of the contact has an influence on the conductivity, and the contact 4 with good conductivity can have lower temperature rise performance, the effectiveness of the contact is verified through experiments.

Firstly, for a common brass material, especially for a structure of the integrated contact 3 without the contact 4, under a test current of 12A, the test data are as follows:

TABLE 1

It is worth to be noted that the electric corrosion condition is judged by the temperature rise coefficient and the end face form after 5000 contact experiments, the exceeding standard is over the safety standard, and the electric corrosion condition can not be used continuously when the electric corrosion condition does not meet the corresponding standard. It can be seen that after testing, the temperature rise coefficient of the integrated contact 3 structure of the common brass exceeds 45K, the service life is short, and the integrated contact does not meet the 45K temperature rise safety standard.

Then, the structure of the contact 3 of the contact 4 made of silver in the first mode is tested, which specifically includes the following steps:

TABLE 2

TABLE 3

The contact 4 with the thickness of 0.2mm and 0.3mm is adopted for optimization, so that the requirement of safe temperature rise is met before testing, the temperature rise index is further reduced after multiple life tests, and meanwhile, the electric corrosion condition is lighter, and the use requirement is met.

The present invention is not limited to the above-mentioned alternative embodiments, and other various products can be obtained by anyone in light of the present invention. The above detailed description should not be taken as limiting the scope of the invention, which is defined in the following claims, and which can be used to interpret the claims.
