The first conducting piece 1 and the second conducting piece 2 are further provided with a first elastic piece 3 and a second elastic piece 4, the first elastic piece 3 and the second elastic piece 4 are located in the first containing cavity 11, the first elastic piece 3 is surrounded outside the second elastic piece 4, one of the first elastic piece 3 and the second elastic piece 4 has higher elasticity than the other, and the other of the first elastic piece 3 and the second elastic piece 4 has smaller resistance value. For example, in the present embodiment, the second elastic member 4 has higher elasticity than the first elastic member 3, and the first elastic member 3 has a smaller resistance value than the second elastic member 4; of course, in other embodiments, the first elastic member 3 has higher elasticity than the second elastic member 4, and the second elastic member 4 has a smaller resistance value than the first elastic member 3, so the present utility model is not limited thereto. By means of the second elastic member 4 having high elasticity, the restoring movement of the second conductive member 2 is powered; by means of the first elastic piece 3 with a small resistance value, the second conducting piece 2 always keeps electrical conduction when sliding relative to the first conducting piece 1, and the current is kept from being cut off instantaneously.
More specifically, the following are given: the first elastic member 3 and the second elastic member 4 are springs. Of course, in other embodiments, the first elastic member 3 and the second elastic member 4 are elastic columns or other elastic structures, and are not limited thereto. For example, in the present embodiment, the first elastic member 3 has a smaller resistance value, the second elastic member 4 has a higher elasticity, and the first elastic member 3 is a copper alloy spring or a copper spring, so that the first elastic member 3 is not burned out while ensuring good electrical conductivity. The second elastic member 4 is a stainless steel spring, so as to provide high elasticity and high fatigue resistance, and the resistance value of the second elastic member 4 is higher than that of the first elastic member 3, so that the current passing through the second elastic member 4 is very small, and therefore, the second elastic member 4 cannot be easily burnt out, which is beneficial to improving the overall life of the never-to-break connector 100 of the utility model. Of course, the second elastic member 4 has a higher elasticity and a higher resistance, for example, the second elastic member 4 may be a high-elasticity insulating structure, which is not limited thereto. Of course, in other embodiments, when the first elastic member 3 has higher elasticity and the second elastic member 4 has smaller resistance, the first elastic member 3 is a stainless steel spring, and the second elastic member 4 is a copper spring or a copper alloy spring, which is not limited thereto.

The first elastic piece 3 and the second elastic piece 4 are separated by the aid of the separating piece 5, so that the first elastic piece 3 and the second elastic piece 4 are difficult to contact, the stability of current is guaranteed, and the safety is improved while the guiding effect is provided for the elastic movement of the first elastic piece 3. Specifically, the second conducting piece 2 is sleeved with the isolating piece 5 in a relative sliding manner, specifically, the second conducting piece 2 is sleeved on the isolating piece 5, so that the stability of sliding and stretching of the second conducting piece 2 is ensured, meanwhile, the maximum displacement of downward sliding of the second conducting piece 2 is also increased, the stretching flexibility of the second conducting piece is improved, and the second conducting piece is more suitable for occasions with large vibration. Of course, in other embodiments, the spacer 5 is sleeved on the second conductive member 2, so it is not limited thereto. Preferably, the end of the second conducting member 2 is provided with a third accommodating cavity 21 communicated with the second accommodating cavity 51, and the second elastic member 4 is located in both the second accommodating cavity 51 and the third accommodating cavity 21. Compared with the second conducting piece 2 with a traditional solid structure, the integral size of the permanent non-instantaneous-disconnection connector 100 can be reduced, so that the connector is suitable for occasions with small size.
Preferably, in the present embodiment, the spacer 5 is a conductive member, so as to add a new conduction path for the current to flow. It is understood that the second conductive element 2 and the first conductive element 1 are both conductive bodies, which are well known to those skilled in the art. Since the second conducting member 2 is sleeved on the isolating member 5, the inner side wall of the second conducting member 2 contacts with the outer wall of the isolating member 5, and the current can be conducted between the first conducting member 1, the isolating member 5 and the second conducting member 2 sequentially or reversely. Of course, in other embodiments, the spacer 5 may be an insulating structure, and is not limited thereto. Specifically, in the present embodiment, the outer contour of the spacer 5 is cylindrical.
Referring to fig. 3, a first chamfer 54 is circumferentially disposed on an inner side wall of the spacer 5 toward one end of the second conductive member 2, and the first chamfer 54 helps to reduce the difficulty of assembling the second elastic member 4 during the assembling process of the spacer 5. The second chamfer 24 is circumferentially arranged on the inner side wall of the second conducting piece 2 towards one end of the isolating piece 5, and the second chamfer 24 is used for reducing the assembly difficulty in the assembly process of the isolating piece 5 and the second conducting piece 2.
Referring to fig. 3, the first conductive element 1 has a limiting portion 12 for limiting the second conductive element 2 from being separated, and a step portion 22 abutting against the limiting portion 12 is protruded outward from the end portion of the second conductive element 2. Specifically, the limiting portion 12 is formed by bending or bending an edge of the sidewall of the first conductive member 1 inward. The step portion 22 is located between the limiting portion 12 and the bottom of the first accommodating cavity 11. The second conductive member 2 is prevented from being completely separated from the first conductive member 1 by the stopper 12 and the step portion 22.
Specifically, in the present embodiment, the bottom surface of the first accommodating cavity 11 is a concave structure 13 with its periphery inclined downward toward the center, and the bottom surface of the spacer 5 is a curved surface 52 protruding toward the concave structure 13, so that the spacer 5 can be vertically and stably connected in the first accommodating cavity 11. It is understood that the second conductive member 2 is slidable in the axial direction of the spacer 5.
Referring to fig. 2 and 3, the tail portion of the first conductive element 1 further protrudes with a plug 14. The top surface of the second conductive member 2 is a spherical surface 23.
