Description

Technical Field

[0001] This utility model belongs to the field of electrical connector sheath technology. Specifically, this utility model relates to an electrical connector sheath mounting structure. Background Technology

[0002] Electrical connector sleeves are used for the protection, limiting, and installation of terminal blocks. They are widely used in the connection and fixation between automotive wiring harnesses and electrical appliances. Existing sleeves have complex structures and high costs; they are also prone to stiffness during insertion and rolling under torsional force, resulting in poor contact between the terminal block and the mating connector, poor reliability, and easy customer complaints.

[0003] Utility model patent CN 209366876U, published on September 10, 2019, discloses a sheath for automotive glass terminals. The sheath includes a plate with a pressure plate protruding upwards from the middle and a limiting plate at the end. The pressure plate is integrally formed with the plate on both sides, with insertion holes for terminals to be inserted at both ends. A positioning hole for the terminal ends to be inserted is formed between the limiting plate and the plate. However, this sheath for automotive glass terminals does not solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an electrical connector sheath mounting structure that is simple in structure, low in cost, and highly reliable.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The electrical connector sheath mounting structure includes a wire harness end sheath and an appliance end socket. The wire harness end sheath includes a sheath body, a longitudinal arm on one side of the sheath body, a locking block on the longitudinal arm, and a locking opening on the side of the appliance end socket that cooperates with the locking block.

[0007] The sheath body is also provided with a horizontal arm, and the horizontal arm and the vertical arm are arranged in a T-shape; the two ends of the horizontal arm are fixedly connected to the two sides of the sheath body respectively, and the two ends of the vertical arm are fixedly connected to the middle of the horizontal arm and the bottom of the sheath body respectively.

[0008] The sheath body has limiting plates on both sides, and the electrical appliance socket has slots on both sides that cooperate with the limiting plates. The slots are U-shaped.

[0009] The limiting plate has longitudinal ribs on its side.

[0010] The sheath body has a rectangular groove in the middle of its bottom end, and the electrical appliance socket has a rectangular protrusion corresponding to the rectangular groove.

[0011] The card block has a barbed structure.

[0012] The inner side of the appliance terminal socket is provided with a limiting groove that is adapted to the longitudinal arm.

[0013] The technical advantages of this utility model are as follows: The electrical connector sheath installation structure of this utility model features a reasonable combination of a limiting plate and a rectangular groove on the wire harness end sheath, ensuring reliable positioning and completely solving the problem of poor contact between the wiring terminals and mating connectors caused by torsion of the wire harness end sheath. A rectangular groove at the bottom of the sheath body cooperates with a rectangular protrusion in the middle of the appliance socket to prevent torsion of the wire harness end sheath. Longitudinal ribs on the limiting plate form line contact with the groove, reducing the contact area and eliminating stiffness during insertion. They also provide guidance during wire harness end sheath assembly. The locking structure is a barbed snap-fit ​​structure, which is ingenious, simple, practical, easy to disassemble, and low in cost. Attached Figure Description

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0021] like Figures 1 to 4As shown, the electrical connector sheath mounting structure includes a wire harness end sheath 1 and an appliance end socket 2. The wire harness end sheath 1 includes a sheath body 17, with a longitudinal arm 12 on one side and a locking block 13 on the longitudinal arm 12. The appliance end socket 2 has a locking opening 21 on its side that cooperates with the locking block 13. The electrical connector sheath mounting structure includes two parts: the wire harness end sheath 1 and the appliance end socket 2. The wire harness end sheath 1 includes a sheath body 17, which has a rectangular structure. The appliance end socket 2 has a recessed structure, and a T-shaped locking structure is provided on the side of the sheath body 17. A barbed locking block 13 is added to the longitudinal arm 12 of the T-shaped locking structure. The locking block 13 cooperates with the locking opening 21 at the bottom of the U-shaped structure of the appliance end socket 2, thereby fixing the wire harness end sheath 1 to the appliance end socket 2. When disassembling the wire harness end sleeve 1 from the appliance end socket 2, simply press and pull the cross arm 11 of the T-shaped locking structure upwards to separate the wire harness end sleeve 1 from the appliance end socket 2.

[0022] like Figure 1 As shown, the sheath body 17 is also provided with a horizontal arm 11, and the horizontal arm 11 and the vertical arm 12 are arranged in a T-shape. The two ends of the horizontal arm 11 are fixedly connected to the two sides of the sheath body 17, and the two ends of the vertical arm 12 are fixedly connected to the middle part of the horizontal arm 11 and the bottom end of the sheath body 17, respectively. In the above structure, the horizontal arm 11 is only connected to the sheath body 17 at both ends, and the vertical arm 12 is only connected to the sheath body 17 at the bottom end. That is, there is a certain space between the middle area of ​​the horizontal arm 11 and the non-bottom area of ​​the vertical arm 12 and the sheath body 17. When the horizontal arm 11 is pressed, the deformation of the horizontal arm 11 will drive the vertical arm 12 to deform and move a certain distance towards the sheath body 17, thereby separating the locking block 13 from the locking opening 21, thus releasing the lock between the wire harness end sheath 1 and the appliance end socket 2. Furthermore, the horizontal arm 11 is located outside the appliance end socket 2 without structural obstruction, making operation simple and convenient, and facilitating the insertion and removal maintenance of the wire harness end sheath 1.

[0023] like Figure 3 As shown, the sheath body 17 has limiting plates 14 on both sides, and the appliance end socket 2 has slots 22 on both sides that mate with the limiting plates 14. The slots 22 are U-shaped. The limiting plates 14 are symmetrically arranged on both sides of the sheath body 17, and the limiting plates 14 mate with the slots 22 on both sides of the U-shaped structure of the appliance end socket 2. The mate between the limiting plates 14 and the slots 22 can not only prevent the wire harness end sheath 1 from being twisted under force, thus solving the problem of easy slippage and poor reliability of the sheath structure under torsional force; the limiting plates 14 also have a limiting and guiding function when the wire harness end sheath 1 and the appliance end socket 2 are assembled.

[0024] like Figure 3As shown, the side of the limiting plate 14 is provided with longitudinal ribs 15. Longitudinal ribs 15 are provided on all three sides of the limiting plate 14. The U-shaped groove 22 is in contact with the longitudinal ribs 15 on the three sides of the limiting plate 14. The longitudinal ribs 15 are in line contact with the inner wall of the groove 22. This design results in a small contact area and eliminates the sticking phenomenon during insertion.

[0025] like Figure 3 and Figure 4 As shown, a rectangular groove 16 is provided in the middle of the bottom end of the sheath body 17, and a rectangular protrusion 23 corresponding to the rectangular groove 16 is provided on the appliance end socket 2. The rectangular groove 16 and the rectangular protrusion 23 in the middle of the appliance end socket 2 cooperate to prevent the wire harness end sheath 1 from being twisted by force.

[0026] like Figure 1 As shown, the locking block 13 has a barbed structure. The barbed locking block 13 has a reliable anti-dislodgement function, and one side of the locking block 13 is designed with an inclination to provide guidance during installation.

[0027] like Figure 4 As shown, the inner side of the appliance end socket 2 is provided with a limiting groove 24 that matches the longitudinal arm 12. The limiting groove 24 plays a horizontal limiting role for the longitudinal arm 12, which helps to further prevent the wire harness end sheath 1 from twisting.

[0028] like Figure 3 As shown, the top of the sheath body 17 has a socket 18 with the open end of the socket 18 pointing vertically upward, which is consistent with the insertion and removal direction of the wire harness end sheath 1, making it convenient for wire harness management.

[0029] Example: The electrical connector sheath is a wire harness end sheath 1 that mates with the appliance end socket 2 located on the oil pump. The bottom of the appliance end socket 2 is fixedly connected to an end cover with a stepped structure for easy snap-fit ​​installation on the oil pump. Other areas of the end cover are also designed with other types of connector sockets, achieving multi-purpose functionality and facilitating wire harness management.

[0030] During installation, the harness end sleeve 1 is installed on the appliance end socket 2 from top to bottom, ensuring that the limiting block abuts against the slot 22, and the locking block 13 enters the locking opening 21 and engages with it to fix the sleeve. At the same time, the rectangular slot 16 and the rectangular protrusion 23 cooperate. During disassembly, press the horizontal arm 11 of the T-shaped locking structure to separate the locking block 13 from the locking opening 21, and pull the harness end sleeve 1 upward to separate the harness end sleeve 1 from the appliance end socket 2. This locking structure is simple, highly reliable, easy to disassemble, and has good maintainability.

[0031] The mounting structure of this electrical connector sheath features a reasonable arrangement of a limiting plate 14 and a rectangular groove 16 on the wire harness end sheath 1, ensuring reliable positioning and completely solving the problem of poor contact between the terminal block and the mating connector caused by the wire harness end sheath 1 being twisted under force. The bottom of the sheath body 17 has a rectangular groove 16 that mates with the rectangular protrusion 23 in the middle of the appliance end socket 2, preventing the wire harness end sheath 1 from being twisted under force. The limiting plate 14 has a longitudinal rib 15 that forms line contact with the groove 22, reducing the contact area between the two and eliminating the sticking phenomenon during insertion. It also has a guiding function during the assembly of the wire harness end sheath 1. The locking structure is a barbed snap-lock structure, which is ingenious, simple and practical, easy to disassemble, and low in cost.

[0032] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
