[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A protective electrical connector includes an electrical connector body 1, a protective structure 2 inserted into the inner side of the electrical connector body 1, and a support structure 3 bolted to the outer side of the protective structure 2.

[0028] The protective structure 2 includes a rubber pad 21, a mounting frame 22, a connecting bracket 23, and a fastener 24. The rear side of the rubber pad 21 contacts the front side of the electrical connector body 1, the rear side of the rubber pad 21 is bonded to the front side of the mounting frame 22, the outer side of the mounting frame 22 is inserted into the inner side of the electrical connector body 1, the inner side of the connecting bracket 23 is sleeved with the outer side of the mounting frame 22, the front side of the connecting bracket 23 contacts the rear side of the electrical connector body 1, the inner wall of the fastener 24 is threaded to the outer wall of the mounting frame 22, and the front side of the fastener 24 contacts the rear side of the connecting bracket 23.

[0029] In this embodiment: the electrical connector body 1 serves as the core carrier for electrical connection, providing a foundation for circuit conduction and enabling the transmission of electrical energy or signals between devices. The protective structure 2, in which the rubber pad 21 provides a sealed protection for the installation of the electrical connector body 1, prevents external dust, moisture, impurities, etc. from entering the connection part, and prevents short circuits or component corrosion. The mounting frame 22 serves as a support carrier in the protective structure 2, providing an installation reference for the rubber pad 21, the connecting frame 23, and the fasteners 24. The connecting frame 23 serves as the basic frame connecting the protective structure 2 and the support structure 3. The fasteners 24 allow the user to firmly lock the connecting frame 23 and the mounting frame 22 by tightening them, thus achieving a tight fixation between the protective structure 2 and the electrical connector body 1.

[0030] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, the support structure 3 includes a connecting shell 31, the inner side of which is bolted to the outer side of the connecting frame 23.

[0031] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, a positioning member 32 is bolted to the rear side of the connecting shell 31. There are two connecting shells 31 and two positioning members 32. A fixing shell 33 is snapped into the inner side of the positioning member 32.

[0032] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, the inner side of the fixing shell 33 is sleeved with the outer side of the electrical connector body 1, and a rubber part 34 is bonded to the inner side of the fixing shell 33. The inner side of the rubber part 34 is sleeved with the outer side of the electrical connector body 1.

[0033] In this embodiment: By setting a support structure 3, in which the connecting shell 31 provides installation support for the positioning member 32, and by bolting it to the connecting frame 23, the support structure 3 and the protective structure 2 are tightly connected. The positioning member 32 provides positioning and installation support for the fixing shell 33, ensuring that the fixing shell 33 fits snugly against the outer side of the electrical connector body 1. The fixing shell 33 provides external protection for the electrical connector body 1, blocking external collisions or wear. The rubber pad 21 fills the outside of the fixing shell 33 and the electrical connector body 1 cable, improving the sealing and protection effect, and at the same time playing a buffering and vibration reduction role to prevent bending from causing damage to the circuit.

[0034] Specifically, such as Figure 5 As shown, the electrical connector body 1 has a mounting groove 4 on the front side and a mounting hole 5 on the rear side, and the mounting groove 4 and the mounting hole 5 are connected.

[0035] Specifically, such as Figure 2, Figure 4 , Figure 6 As shown, there are four fasteners 24, which are respectively set on the outer wall of the mounting frame 22. The outer wall of the fasteners 24 is provided with anti-slip texture.

[0036] In this embodiment: the mounting groove 4 and mounting hole 5 are respectively opened in the electrical connector body 1 to provide fitting space for the rubber pad 21 and mounting frame 22 to be installed in conjunction with the electrical connector body 1, ensuring that the protective structure 2 is embedded, so that the rubber pad 21 is tightly fitted to the front side of the electrical connector body 1, achieving the effect of sealing and protection.

[0037] Specifically, such as Figure 3 As shown, both sides of the fixed shell 33 are provided with mating grooves 6, and the inner side of the mating groove 6 is engaged with the outer side of the positioning member 32.

[0038] Specifically, such as Figure 2 , Figure 3 As shown, connecting holes 7 are provided on both sides of the connecting shell 31, and threaded holes 8 are provided on both sides of the connecting bracket 23. The connecting holes 7 and the threaded holes 8 are connected.

[0039] In this embodiment: the mating groove 6 provided by the fixed shell 33 provides a snap-fit ​​position for the positioning member 32, ensuring that the fixed shell 33 and the positioning member 32 are quickly positioned and firmly connected, and preventing the fixed shell 33 from loosening. The connecting hole 7 provided by the connecting shell 31 and the threaded hole 8 provided by the connecting bracket 23 provide a channel for fixing the connecting shell 31 and the connecting bracket 23, so as to facilitate the firm connection of the two by bolts, and ensure that the support structure 3 and the protective structure 2 are tightly connected.

[0040] Working principle: This protective electrical connector uses the connector body 1 as its core carrier, providing the foundation for circuit conduction. The mounting slot 4 and mounting hole 5 provide fitting space for the protective structure 2, ensuring precise installation of the protective components. The protective structure 2 forms the first line of defense, with the rubber pad 21 fitting against the front of the connector body 1 to prevent dust or moisture intrusion. The mounting frame 22 is embedded inside the body, serving as a support reference for the protective components. The connecting bracket 23 is fitted onto the outside of the mounting frame 22 and fits against the rear of the connector body 1. Fasteners 24... After tightening, the connecting frame 23 and the mounting frame 22 are locked together, so that the protective structure 2 and the electrical connector body 1 are tightly fixed. The support structure 3 is used for external protection. The connecting shell 31 is firmly connected to the connecting frame 23 by bolts. The positioning part 32 is inserted into the mating groove 6 of the fixed shell 33 to achieve precise positioning of the fixed shell 33 and the connecting shell 31. The fixed shell 33 is fitted on the outside of the electrical connector body 1, and the inner rubber part 34 fills the gap, which not only enhances the sealing effect, but also buffers vibration to prevent the line from bending, and blocks external collision and wear, ensuring the long-term stability of the electrical connection.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
