Description

Technical Field

[0001] This utility model relates to the field of wire terminal installation technology, and specifically to an electrical connector structure for wire terminals. Background Technology

[0002] Wire terminals are essential basic components in electrical connections. They are typically composed of a metal conductor and an external insulator. Their core function is to provide a standardized, safe, and reliable connection interface for the end of the wire. Through crimping, welding, or screw fastening, wire terminals ensure a firm connection between the wire and equipment terminals, other wires, or grounding points, effectively preventing wire loosening, oxidation, and short circuits. This greatly improves the stability, safety, and ease of maintenance of electrical systems, and they are widely used in many fields such as distribution boxes, automotive wiring harnesses, industrial equipment, and household appliances.

[0003] However, to prevent interference from external factors when installing the wire terminal lugs using screw tightening, a protective cover is required on the outside of the connector to house the wire terminal connection within the connector and the protective cover. However, most existing protective covers are fixed with bolts, requiring repeated tightening to secure them, which is cumbersome. Therefore, there is an urgent need for an electrical connector structure that integrates wire terminal installation and protection. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this application provides an electrical connector structure for wire terminals. A protective plate is installed via a plug-in method, housing the wire terminal lugs within the connector cavity. Simultaneously, a threaded rod drives the displacement of a limiting pressure plate and a fixing cylinder, fitting the fixing cylinder onto the terminal block to achieve wire terminal lug installation. The protective plate, under the reaction force of the limiting pressure plate and the fixing cylinder, is pressed tightly against the inner wall of the slot, thus limiting the protective plate's position. This reduces the inconvenience of repeatedly tightening bolts, improves installation efficiency, and solves the problems mentioned in the background art.

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

[0006] An electrical connector structure for a wire terminal includes: a connector base, a fixing base disposed within the inner cavity of the connector base, a terminal block disposed on the upper end face of the fixing base and connected to an internal electrical component, a wire terminal lug fitted onto the outside of the terminal block, a protective plate disposed at the top opening of the inner cavity of the connector base, a side plate disposed on one side of the protective plate covering the side opening of the inner cavity of the connector base, and a limiting pressure plate disposed below the protective plate within the inner cavity of the connector base, a threaded rod disposed on the upper end face of the limiting pressure plate, the threaded rod being threadedly installed inside the protective plate and extending above it, and the limiting pressure plate being able to move up and down within the inner cavity of the connector base by rotating the threaded rod, and a fixing cylinder disposed on the lower end face of the limiting pressure plate, the fixing cylinder being fitted onto the outside of the terminal block and pressing the wire terminal lug.

[0007] Preferably, the inner wall of the connector has a slot, and the protective plate is inserted into the slot to cover the top and side openings of the inner cavity of the connector.

[0008] Preferably, a threaded hole is provided at the end face of the protective plate corresponding to the position of the threaded rod, and the threaded rod is threadedly installed inside the threaded hole.

[0009] Preferably, the threaded rod is threaded onto one end above the protective plate, with a rotating wheel for driving it to rotate.

[0010] Preferably, a limiting nut is provided on the outer wall of the threaded rod between the rotating wheel and the protective plate. The limiting nut is threaded onto the outer wall of the threaded rod and closely attached to the upper end face of the protective plate. The internal thread of the limiting nut is opposite in direction to the internal thread of the threaded hole.

[0011] Preferably, the lower end face of the fixing cylinder is provided with an insertion hole, and the fixing cylinder is fitted onto the outside of the terminal block through the insertion hole.

[0012] Preferably, the end face of the side plate is provided with an arc-shaped through groove, and the side plate is fitted onto the outside of the wire terminal connection wire through the arc-shaped through groove.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] By setting up a protective plate and a limiting pressure plate, the protective plate can be inserted into the slot. The top and side openings of the connector are sealed by the protective plate and side plate, and the wire terminal lugs are housed in the inner cavity of the connector, preventing the connection end of the wire terminal from being exposed to the air and affected by the external environment, thus protecting the connection end of the wire terminal. At the same time, the limiting pressure plate driven by the threaded rod moves the fixing cylinder downward, and the fixing cylinder is fitted onto the outside of the terminal block to press the wire terminal lugs, thus limiting the wire terminal lugs. Moreover, after the fixing cylinder presses the wire terminal lugs, the protective plate can be pressed against the inner wall of the slot by the reaction force of the limiting pressure plate and the fixing cylinder, thus limiting the protective plate, reducing the trouble of repeatedly tightening the bolts, and improving installation efficiency.

[0021] Combination Figures 1-4 As shown, in this embodiment, an electrical connector structure for a wire terminal includes: a connecting base 1, a fixing base 11 is provided in the inner cavity of the connecting base 1, a terminal block 12 is provided on the upper end surface of the fixing base 11 and is connected to the internal electrical components, and a wire terminal lug is fitted on the outside of the terminal block 12; by fitting the wire terminal lug on the terminal block 12, the wire terminal is connected to the internal electrical components of the fixing base 11, thus satisfying the use of the wire terminal.

[0022] In this embodiment, a protective plate 2 is provided at the top opening of the inner cavity of the connector 1, and a side plate 21 is provided on one side of the protective plate 2, which covers the side opening of the inner cavity of the connector 1. By inserting the protective plate 2 into the slot 101 in the inner wall of the connector 1, the top and side openings of the inner cavity of the connector 1 are covered by the protective plate 2 and the side plate 21, thereby sealing the connector 1. This allows the connection end of the wire terminal to be housed in the inner cavity of the connector 1, preventing the connection end of the wire terminal from being exposed to the air and affected by the external environment, thus protecting the connection end of the wire terminal.

[0023] In this embodiment, a limiting pressure plate 3 is provided in the inner cavity of the connecting seat 1 below the protective plate 2. A threaded rod 32 is provided on the upper end face of the limiting pressure plate 3. The threaded rod 32 is threadedly installed inside the protective plate 2 and extends to its upper part. By driving the threaded rod 32 to rotate, the threaded rod 32 is moved downward in the threaded hole 201, and pushes the limiting pressure plate 3 to move downward in the inner cavity of the connecting seat 1, so as to satisfy the position adjustment of the limiting pressure plate 3.

[0024] In this embodiment, a fixing cylinder 31 is provided on the lower end face of the limiting pressure plate 3. The fixing cylinder 31 is fitted on the outside of the terminal block 12 to press the wire terminal lug. The fixing cylinder 31 can be moved downward with the displacement of the limiting pressure plate 3, so that the fixing cylinder 31 is fitted on the outside of the terminal block 12 through the insertion hole 311 and presses the wire terminal lug, thereby realizing the installation and limiting of the wire terminal lug.

[0025] In this embodiment, a rotating wheel 34 for driving rotation is threaded onto one end of the threaded rod 32 located above the protective plate 2; the rotating wheel 34 drives the threaded rod 32 to rotate in the forward and backward directions, allowing the threaded rod 32 to move downward and upward in the threaded hole 201, thereby driving the threaded rod 32.

[0026] In this embodiment, a limiting nut 33 is provided on the outer wall of the threaded rod 32 between the rotating wheel 34 and the protective plate 2. The limiting nut 33 is threaded onto the outer wall of the threaded rod 32 and closely attached to the upper end face of the protective plate 2. The internal thread of the limiting nut 33 is opposite to the internal thread of the threaded hole 201. After the fixed cylinder 31 is used to limit the position of the wire terminal lug, the limiting nut 33 can be screwed on the end face of the protective plate 2 to limit the position of the threaded rod 32. This prevents the limiting pressure plate 3 and the fixed cylinder 31 from loosening due to the rotation of the threaded rod 32, thereby improving the stability of the wire terminal lug installation.

[0027] In this embodiment, the end face of the side plate 21 is provided with an arc-shaped through groove 211. The side plate 21 is fitted onto the outside of the wire terminal connection line through the arc-shaped through groove 211. This allows the side plate 21 to be fitted onto the outside of the wire terminal connection line through the arc-shaped through groove 211, preventing the wire terminal connection line from interfering with the installation of the side plate 21 and facilitating the wiring of the wire terminal connection line.

[0028] The working principle of this utility model is as follows: The electrical connector proposed in this application, by inserting the protective plate 2 into the slot 101 in the inner wall of the connector 1, and the protective plate 2 and the side plate 21 covering the top and side openings of the inner cavity of the connector 1, achieves the closure of the connector 1, which can house the connection end of the wire terminal in the inner cavity of the connector 1, preventing the connection end of the wire terminal from being exposed to the air and affected by the external environment, thus protecting the connection end of the wire terminal. Then, the rotating wheel 34 drives the threaded rod 32 to rotate, so that the threaded rod 32 moves downward in the threaded hole 201, and pushes the limiting pressure plate 3 to drive the fixing cylinder 31 to move downward, so that the fixing cylinder 31 is fitted on the outside of the terminal block 12 to press the wire terminal lug, thus realizing the installation and limiting of the wire terminal lug. At the same time, after the fixing cylinder 31 presses the wire terminal lug, the protective plate 2 can be pressed against the inner wall of the slot 101 under the reaction force of the limiting pressure plate 3 and the fixing cylinder 31, thus limiting the protective plate 2, reducing the trouble of repeatedly tightening the bolts, and improving the installation efficiency.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
