Description

Technical Field

[0001] The utility model relates to the field of new energy connectors, and more specifically, the utility model relates to a shielding sleeve and a connector using the shielding sleeve. Background Art

[0002] In the current structure of new energy connectors, after the shielding member is crimped to the shielding wire, the tail of the shielding member is deformed to form a relatively sharp cut. During the contact between the cut and the wire sealing body, there is a risk of piercing the wire sealing body, resulting in sealing failure. In the prior art, it is necessary to additionally install a baffle behind the shielding member to block the cut at the tail of the shielding member and prevent piercing the wire sealing body. However, adding a baffle increases the installation steps and there is a risk of missing installation; after the product assembly is completed, it is also very difficult to detect whether the baffle is missing, so there is still a relatively large safety risk. Summary of the Utility Model

[0003] The utility model overcomes the deficiencies of the prior art and provides a shielding sleeve and a connector using the shielding sleeve, in the hope of solving the problem that the tail of the shielding member pierces the wire sealing body existing in the prior art.

[0004] To solve the above technical problems, on the one hand, the utility model provides a shielding sleeve:

[0005] A shielding sleeve includes a sleeve and a boss;

[0006] The sleeve is tubular, and the boss is located at the end of the sleeve;

[0007] The boss extends outward from the sleeve, the diameter of the boss is larger than the diameter of the sleeve, and the extended part of the boss is perpendicular to the sleeve.

[0008] The boss part can play the role of a baffle. After the tail of the shielding member is crimped and deformed, since the boss is provided at the tail of the shielding member, the upper plane of the boss contacts the wire sealing body, and there will be no piercing problem; and since the boss is integrated on the shielding sleeve, no new installation steps will be added during installation, and it can be confirmed whether the shielding sleeve is installed after installation, avoiding the problem of missing installation.

[0009] A further technical solution is that the shielding sleeve is made of copper alloy.

[0010] Copper alloy has good ductility during use, is not easily damaged during crimping deformation, and has good electrical and thermal conductivity.

[0011] The utility model also provides a connector.

[0012] A connector includes the above-mentioned shielding sleeve, outer sleeve, cable, and wire sealing body;

[0013] A sealing body and a shielding sleeve are successively sleeved on the outer side of the cable from top to bottom, and the boss of the shielding sleeve abuts against the sealing body;

[0014] The outer sleeve is sleeved outside the shielding sleeve;

[0015] The cable includes shielding wires, and the shielding wires are folded between the shielding sleeve and the outer sleeve.

[0016] The shielding wires in the cable are folded in the shielding sleeve and the outer sleeve and are crimped; after the crimping is completed, the shielding wires are electrically connected; the boss of the shielding sleeve restricts the movement of the sealing body to realize the function of the baffle.

[0017] Furthermore, a fixing bayonet is arranged on the boss, and the fixing bayonet is located on the side of the boss away from the sleeve;

[0018] Fixing teeth matching the fixing bayonet are arranged on the outer sleeve.

[0019] By arranging the fixing bayonet and the fixing teeth, the relative rotational movement between the outer sleeve and the shielding sleeve can be restricted, the stability of the connector is improved, and the shielding wires are prevented from being damaged.

[0020] Even further, the connector further includes a tail clip, and the tail clip is sleeved on the outer side of the cable;

[0021] The lower part of the tail clip abuts against the upper part of the sealing body.

[0022] The tail clip restricts the upward movement of the sealing body to ensure the sealing reliability.

[0023] Even further, the connector further includes a housing, and the housing is sleeved on the outer sides of the outer sleeve and the sealing body;

[0024] The upper part of the housing abuts against the lower part of the tail clip.

[0025] Even further, the number of the cables is greater than 1;

[0026] The cables pass through the through holes arranged on the tail clip and the sealing body, and shielding sleeves are sleeved on the outer sides of the cables passing through the sealing body, and the bosses of the shielding sleeves abut against the sealing body.

[0027] Compared with the prior art, the utility model has at least the following beneficial effects: Compared with the current technical state, the utility model integrates the function of the baffle on the shielding sleeve, forms a barrier for the tail cut of the shielding part, and avoids piercing the sealing body. Moreover, by integration, the risk of missing installation of the baffle is eliminated, the number of parts of the connector is reduced, the assembly process is reduced, the safety performance is improved, and the cost is reduced.
