Description

Technical Field

[0001] This utility model belongs to the technical field of wire harnesses, and in particular relates to a press-type quick-unlocking plug-in device for rail transit wire harnesses. Background Technology

[0002] A patent titled "Wire Harness Connector" is disclosed in the existing Chinese patent database, with application number CN202323047659.6 and application date of 2023-11-11. Specifically, it is a wire harness connector, including a female and a male connector. The female and male connectors are connected, and an electrical signal wire runs through them. An O-ring is placed on the male connector. The electrical signal wire and one end of the male connector pass through the gas appliance housing. On the other side of the gas appliance housing, a nut connects the male connector. A socket is opened in the center of the top of the female connector. The male connector is inserted into the inner wall of the female connector through a socket, forming a cavity one in the inner wall of the female connector. A cavity two is formed in the middle of the bottom of the male connector. Epoxy resin is injected into cavities one and two. This utility model provides that epoxy resin fills cavities one and two, and seals the cavities and the multiple sets of wire harness gaps inside the cavities to prevent gas from leaking out from the gaps in the wire harness. Furthermore, the female and male connectors fix the wire harness to the gas equipment housing, solving the problem of wire harness sheath wear caused by friction at the beginning of the round hole in the housing.

[0003] During the operation of rail transit vehicles, the joints of existing rail transit wiring harnesses are at risk of detachment due to the vibration and shaking of the vehicle body. Therefore, this paper aims to propose a press-type quick-unlocking plug-in device for rail transit wiring harnesses, which can lock and limit the connection of the wiring harness to prevent the connection from falling off and improve the safety of the wiring harness. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing rail transit wiring harnesses are at risk of joint detachment during vehicle operation due to vibration and shaking of the vehicle body. In order to improve its shortcomings, this utility model provides a press-type quick unlocking plug-in device for rail transit wiring harnesses.

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

[0006] A quick-release plug-in device for rail transit wire harnesses includes a wire harness body, a male connector, and a female connector. It includes a first connecting sleeve fitted over the female connector. Both sides of the first connecting sleeve have integrally formed horizontal extension sections. Each extension section has an integrally formed elongated block with a through groove. The male connector is fitted with a second connecting sleeve. The second connecting sleeve, directly opposite the through groove, has an integrally formed plug-in locking strip. The free end of the plug-in locking strip has an integrally formed wedge-shaped limiting section.

[0007] Compared with the prior art, the beneficial effects of this utility model are: due to the setting of the first connecting sleeve and the second connecting sleeve, the female connector and the male connector form a snap-lock limit after connection, and the connector connection is not easy to fall off during use, which greatly improves the safety during use. It is suitable for industrial production and has strong practicality.

[0008] As a preferred embodiment, the elongated blocks are provided in four sets, respectively located on the upper and lower surfaces of the extension section of the first connecting sleeve, with the wedge-shaped limiting sections on the upper and lower sides of the extension section facing opposite directions. The oppositely positioned wedge-shaped limiting sections prevent the vehicle body from shifting in one direction due to inertia during travel, thus avoiding detachment from the elongated blocks.

[0009] As a preferred embodiment, both the first and second connecting sleeves have internal threads on their inner sides, and both the female and male connectors have external threads on their root outer surfaces. The female connector is screwed into the first connecting sleeve, and the male connector is screwed into the second connecting sleeve. This spiral connection provides a secondary positioning for both the male and female connectors.

[0010] As a preferred embodiment, the inner end face of the wedge-shaped limiting segment abuts against the end face of the elongated block.

[0011] As a preferred embodiment, both the first connecting sleeve and the second connecting sleeve are made of plastic. The use of plastic components makes the entire device lightweight and reduces replacement costs. 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 push-to-unlock quick-release plug-in device for rail transit wiring harnesses. The wiring harness includes a harness body 1, a male connector 2, and a female connector 3. A first connecting sleeve 4 is fitted over the female connector 3. Horizontal extension sections 5 are integrally formed on both sides of the first connecting sleeve 4. Elongated blocks 6 are integrally formed on the extension sections 5, and through grooves 7 are formed within the elongated blocks 6. A second connecting sleeve 8 is fitted over the male connector 2. A plug-in locking strip 9 is integrally formed on the second connecting sleeve 8 opposite to the through groove 7. A wedge-shaped limiting section 10 is integrally formed on the free end of the plug-in locking strip 9. Four sets of elongated blocks 6 are provided, located on the upper and lower surfaces of the extension sections 5 of the first connecting sleeve 4. The wedge-shaped limiting sections 10 on the upper and lower sides of the extension sections 5 are oriented in opposite directions. The oppositely oriented wedge-shaped limiting sections 10 prevent the vehicle body from shifting in one direction due to inertia during operation, thus avoiding detachment from the elongated blocks 6. Both the first connecting sleeve 4 and the second connecting sleeve 8 have internal threads on their inner sides, while the female connector 3 and the male connector 2 have external threads on their root outer surfaces. The female connector 3 is screwed into the first connecting sleeve 4, and the male connector 2 is screwed into the second connecting sleeve 8. This spiral connection creates a secondary limiting mechanism between the male connector 2 and the female connector 3. The inner end face of the wedge-shaped limiting section 10 abuts against the end face of the elongated block 6. Both the first connecting sleeve 4 and the second connecting sleeve 8 are made of plastic. The use of plastic components makes the entire device lightweight and reduces replacement costs.

[0018] During operation, the operator inserts the female connector 3 and the wire harness body 1 into the first connecting sleeve 4, and simultaneously inserts the male connector 2 and the wire harness body 1 into the second connecting sleeve 8. After completion, the male connector 2 and the female connector 3 are plugged in. At the same time, the wedge-shaped limiting segment 10 of the free end of the insertion clip 9 is inserted into the through groove 7 of the long strip block 6. After the female connector 3 and the male connector 2 are connected, the wedge-shaped limiting segment 10 passes through the through groove 7 and abuts against the end face of the long strip block 6, forming a limiting lock for the connection between the male connector 2 and the female connector 3. When unlocking is required, the wedge-shaped limiting segment 10 is pressed into the inside of the first connecting sleeve 4 to complete the unlocking.

[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.
