Technical Field

[0001] This utility model belongs to the technical field of wire harnesses, and in particular relates to a locking device for preventing accidental contact of rail transit wire harness connectors. Background Technology

[0002] A patent entitled "Wire Harness Connector" is disclosed in the existing Chinese patent database, with application number CN202322862575.1 and application date of 2023-10-24. This wire harness connector includes a connector and a locking cover. The connector includes a mating part and a wiring part. The wiring part has a locking pin, and the locking cover has a locking hole. The locking cover is equipped with a screw, which connects the locking hole and the locking pin to secure the locking cover to the connector. The wiring part has several terminal slots, and pressure seats are provided on both sides of each terminal slot. The locking cover has several wire pressing assemblies, with each terminal slot corresponding to a single wire pressing assembly. Each wire pressing assembly includes a pressure strip and a top strip. The locking cover connects to the wiring part so that the pressure strip and top strip abut against the pressure seat and the terminal slot, respectively. It has advantages such as simple structure, compact fit, and reasonable design; therefore, it is a product with superior technical and economic performance.

[0003] In the prior art, there are no external protective measures at the connection of the wire harness connector, which is easily touched by accident and causes the connector to fall off, thus causing danger. Therefore, this paper aims to propose a locking device to prevent accidental contact of the rail transit wire harness connector. By setting a protective sleeve at the connection point and locking it, the wire harness connection can be prevented from falling off due to accidental contact. Utility Model Content

[0004] The technical problem to be solved by this utility model is that in the prior art, there are no external protective measures at the connection of the wire harness connector, which is easily touched by accident and causes the connector to fall off, thus causing danger. In order to improve its shortcomings, this utility model provides a locking device to prevent accidental contact of rail transit wire harness connector.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A rail transit wire harness connector anti-accidental contact locking device is disclosed. The wire harness includes a wire harness body, a male connector, and a female connector. It includes an outer locking sleeve fitted outside the female connector. An axially oriented opening groove is formed on the outer peripheral surface of the outer locking sleeve. A limit baffle is hinged to the inner wall of the opening groove via a hinge shaft. A torsion spring is provided on the hinge shaft to limit the rotation direction of the limit baffle. It also includes an inner locking sleeve fitted outside the female connector. A limit shaft is integrally formed on the outer peripheral surface of the inner locking sleeve. When the inner locking sleeve is inserted into the outer locking sleeve, the limit shaft presses the limit baffle into the opening groove.

[0007] Compared with the prior art, the beneficial effects of this utility model are: due to the cooperation between the outer locking sleeve and the inner locking sleeve, the connection of the wire harness connector is protected, avoiding the connector from falling off due to accidental contact. Moreover, the outer locking sleeve and the inner locking sleeve form a limit, which can only be unlocked by manually prying the limit baffle. It has high safety and is suitable for industrial production, and has strong practicality.

[0008] As a preferred embodiment, hollow columns are integrally arranged on the inner wall of the opening groove at intervals, the hinge shaft is inserted between the two hollow columns, and the limiting baffle is provided with a through hole for the hinge shaft to pass through.

[0009] As a preferred embodiment, both the outer locking sleeve and the inner locking sleeve have an integrally formed neck on their outer end faces for the wire to pass through, and an elastic rubber sleeve is attached to the inner surface of the neck.

[0010] As a preferred embodiment, the inner bottom surface of the opening groove is semi-circular. Attached Figure Description

[0016] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1-3The diagram shows a locking device to prevent accidental contact of a rail transit wire harness connector. The wire harness includes a wire harness body, a male connector, and a female connector (not shown in the diagram). It includes an outer locking sleeve 1 fitted over the female connector. An axially oriented opening groove 2 is formed on the outer circumferential surface of the outer locking sleeve 1. A limiting baffle 4 is hinged to the inner wall of the opening groove 2 via a hinge shaft 3. A torsion spring 5 is provided on the hinge shaft 3 to limit the rotation direction of the limiting baffle 4. The device also includes an inner locking sleeve 6 fitted over the female connector. A limiting shaft 7 is integrally formed on the outer circumferential surface of the inner locking sleeve 6. When the inner locking sleeve 6 is inserted into the outer locking sleeve 1, the limiting shaft 7 presses the limiting baffle 4, positioning it within the opening groove 2. Hollow cylinders 8 are integrally formed at intervals on the inner wall of the opening groove 2. The hinge shaft 3 passes between two hollow cylinders 8. A through hole is formed on the limiting baffle 4 for the hinge shaft 3 to pass through. Both the outer locking sleeve 1 and the inner locking sleeve 6 have an integrally formed neck 9 for the wire to pass through on their outer end faces, and an elastic rubber sleeve is attached to the inner surface of the neck 9. The inner bottom surface of the opening groove 2 is semi-circular.

[0018] During operation, the operator first inserts the female connector and the wire harness body into the outer locking sleeve 1, and simultaneously inserts the male connector and the wire harness body into the inner locking sleeve 6. In this state, both the outer locking sleeve 1 and the inner locking sleeve 6 are freely slidably connected to the wire harness body. After the connection between the female connector and the male connector is inserted, the outer locking sleeve 1 and the inner locking sleeve 6 are slid axially to the connection point, so that the inner locking sleeve 6 is inserted into the outer locking sleeve 1. During the insertion process, the limiting post presses the limiting baffle 4 to rotate until it passes the limiting baffle 4 and is located in the opening slot 2. Due to the action of the torsion spring 5, the limiting baffle 4 returns to its initial state and hinders the outward movement of the limiting post, thereby locking the outer locking sleeve 1 and the inner locking sleeve 6 together, protecting the connection between the male connector and the female connector, and preventing the connector from falling off due to accidental contact.

[0019] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
