DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] Now, example embodiments will be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this utility model will be more complete and comprehensive, and the concept of the example embodiments will be fully conveyed to those skilled in the art. Like reference numerals in the figures denote the same or similar structures, and thus their repeated description will be omitted.

[0036] The words expressing positions and directions described in the present utility model are illustrative with reference to the drawings, but can be changed as needed, and all such changes are included within the protection scope of the present utility model.

[0037] The present utility model discloses an electrical connector, which is mainly used for the quick connection of internal and external electrical components in a chassis and can be compatible with cables of different sizes.

[0038] Referring to Figures 1 to 4 as shown, the electrical connector includes a panel 1, a conductive part 2, a sealing cylinder 3, a wrench part 4, and a cable gland 5.

[0039] Among them, the panel 1 is configured to be installed on a target component. In this application, the target component is the chassis of various electronic devices (not shown). The panel 1 can be fixed to the chassis by bolts, and a gasket can be provided between the two to meet the requirements of waterproofing and sealing.

[0040] A mating portion 11 is provided on one side of the panel 1 away from the target component. As shown in Figure 2 and Figure 4 , the mating portion 11 is integrally formed with the panel 1, and the inside of the mating portion 11 is hollow. This part is used to house the conductive member 2 and can be assembled with the sealing cylinder 3 to protect the connection end of the external cable 8.

[0041] The conductive member 2 is a strip-shaped metal sheet, which can be made of copper, aluminum, silver, etc. or their alloy materials. As shown in Figure 2 and Figure 4 , one end of the conductive member 2 is located inside the mating portion 11 for docking with the external cable 8, and the other end of the conductive member 2 extends outwards from the panel 1 for docking with the circuit system of the target component, thereby realizing the conduction of the circuit.

[0042] The shape and size of the sealing cylinder 3 are adapted to the mating portion 11. It is preferably made of a lightweight and waterproof material. For example, the sealing cylinder 3 can be a plastic cylinder, an aluminum alloy cylinder, etc. The sealing cylinder 3 is sleeved on the mating portion 11 and forms a sealed space therewith, which is used to waterproof and seal the connection between the conductive member 2 and the external cable 8, thereby improving the safety of the conductive connection.

[0043] Moreover, a wrench member 4 capable of quickly locking the sealing cylinder 3 to the mating portion 11 is provided on the sealing cylinder 3, thereby realizing the quick disassembly and assembly function of the electrical connector. In this application, a clamping block 111 is provided on the mating portion 11. Correspondingly, a clamping groove 421 is provided on the wrench member 4. By operating the position of the wrench member 4, the mating portion 11 and the sealing cylinder 3 can be quickly locked or separated.

[0044] Specifically, the clamping block 111 is in the shape of a convex circular segment, and there are two of them, symmetrically distributed on both sides of the mating portion 11 to ensure the stability and reliability of the locking force. The wrench member 4 includes a rotatable portion 41, a clamping portion 42 and an operating portion 43 which are integrally formed; among them, the rotatable portion 41 is rotatably connected to the sealing cylinder 3, and the clamping groove 421 is located on the clamping portion 42. When in use, the operating portion 43 drives the clamping portion 42 to approach or move away from the mating portion 11 through the rotatable portion 41, causing the clamping groove 421 to quickly engage or disengage with the clamping block 111, thereby realizing the function of quickly locking or separating the mating portion 11 and the sealing cylinder 3.

[0045] The gland 5 is arranged at one end of the sealing cylinder 3 away from the panel 1. It is compatible with external cables 8 of different diameters and can effectively ensure the sealing performance between the sealing cylinder 3 and the external cable 8. In this application, the gland 5 includes elastic claws 51, a sealing ring 52 and a conical cover 53. Among them, the elastic claws 51 are arranged inside the sealing cylinder 3, the sealing ring 52 is arranged inside the elastic claws 51, and the number of the sealing rings 52 is one or more. The conical cover 53 is connected to the sealing cylinder 3, and the conical cover 53 can squeeze the elastic claws 51 to radially contract, causing the sealing ring 52 to closely adhere to the outer circumference of the external cable 8. The gland 5 can be sealed for external cables 8 of different sizes by increasing or decreasing the sealing rings 52 and cooperating with the contraction of the elastic claws 51, which is conducive to on-site cable purchase and construction.

[0046] See Figures 1 to 4 As shown, the assembly process of the above electrical connector is as follows:

[0047] 1. Pass the external cable 8 with the terminals connected through the gland 5 and then send it into the sealing cylinder 3 to make it close to the conductor inside the mating part 11;

[0048] 2. Contact and connect the terminals of the external cable 8 with the conductor to complete the circuit conduction;

[0049] 3. Insert the sealing cylinder 3 towards the mating part 11 and push it to the designated position;

[0050] 4. Pull the wrench part 4 to make the card slot 421 and the block 111 engage with each other, so as to quickly lock the mating part 11 and the sealing cylinder 3 and complete the assembly of the electrical connector.

[0051] The electrical connector of this application adopts a snap-lock assembly method. Compared with the existing screw connection assembly method, its assembly is fast and convenient and the connection is reliable, especially suitable for operation in a construction environment with limited space.

[0052] In addition, the sealing method of the gland 5 is adopted at the tail of the sealing cylinder 3, which can be compatible with external cables 8 of different sizes, is conducive to on-site procurement near the installation site, and thus facilitates construction.

[0053] See Figure 1 and Figure 3 As shown, in some embodiments, the conical cover 53 of the gland 5 is threadedly connected to the sealing cylinder 3, which makes the internal elastic claws 51 and the sealing ring 52 convenient to disassemble and assemble, facilitating subsequent maintenance or replacement operations.

[0054] But in some other embodiments, as Figure 5 shown, the conical cover 53 of the gland 5 can also be integrally formed with the sealing cylinder 3. This is a one-time design, which omits the connection operation between the gland 5 and the sealing cylinder 3 and can effectively improve the assembly efficiency of the electrical connector.

[0055] See Figures 1 to 4As shown, in some preferred embodiments, a locking screw 6 is provided on the wrench member 4, and the locking screw 6 is used for fixedly connecting with the mating portion 11 or the sealing cylinder 3. By means of the locking screw 6, the fixing effect is enhanced, and it can prevent the separation of the card slot 421 and the card block 111 caused by accidental touch or vibration, further improving the locking ability of the wrench member 4.

[0056] It should be noted that the locking screw 6 in this application is special, and it needs to be tightened or unlocked by a customized tool to ensure the safety and reliability of the electrical connector.

[0057] See Figure 2 and Figure 4 As shown, in some embodiments, an operation port 112 is provided on the mating portion 11, and a joining screw 7 is provided at the operation port 112. When wiring, the terminal of the external cable 8 is placed on the conductive member 2, and then the joining screw 7 is tightened from the operation port 112, and the conductive member 2 and the external cable 8 can be connected together.

[0058] Furthermore, nuts 9 are provided at both ends of the conductive member 2. One of the nuts 9 is used to cooperate with the joining screw 7 to facilitate the connection of the external cable 8, and the other nut 9 also plays a cooperative role to facilitate the connection of the circuit system of the target component.

[0059] See Figure 1 As shown, in some embodiments, the plane where the panel 1 is located is parallel to the direction of the external cable 8, and the electrical connector is generally in an L-shaped structure. See Figure 3 As shown, in some other embodiments, the plane where the panel 1 is located is perpendicular to the direction of the external cable 8, and the electrical connector is generally in a linear structure. By designing electrical connectors of different shapes, the connection requirements in different situations can be met.
