[0032] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0033] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the present invention to be protected, but merely represents some embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The present embodiment provides a flameproof electrical connector with waterproof and dustproof effects, comprising a connector body 1, a dustproof component 2 is provided on one side of the connector body 1, and a heat dissipation component 3 is provided on one side of the connector body 1;

[0037] The dustproof component 2 includes a dustproof pad 201, a middle groove 202, a triangular groove 203 and an oblique groove 204. The dustproof pad 201 is arranged on one side of the connector body 1, the middle groove 202 is opened on one side of the dustproof pad 201, the triangular groove 203 is opened on the outer side of the dustproof pad 201, and the oblique groove 204 is opened on the inner circle side of the dustproof pad 201. One end of the oblique groove 204 is inclined upward, and the oblique groove 204 and the triangular groove 203 are staggered. Through the setting of the dustproof pad 201, a physical barrier is formed on one side of the connector body 1 to effectively block the entry of external dust and impurities. The design of the middle groove 202, the triangular groove 203 and the oblique groove 204 further enhances the dustproof effect. They can not only intercept and collect dust, but also guide dust to a specific collection area, thereby keeping the inside of the connector body 1 clean. The design of one end of the oblique groove 204 tilted upward helps to guide dust to the outside of the connector body 1 and reduce the accumulation of dust inside the connector body 1.

[0038] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the heat dissipation assembly 3 includes an annular groove 301, a heat dissipation hole 302 and a heat dissipation groove 303. The annular groove 301 is opened inside the connector body 1, the heat dissipation hole 302 is opened on one side of the annular groove 301, and the heat dissipation groove 303 is opened on one side of the connector body 1. The heat dissipation groove 303 is connected with the inside of the annular groove 301 through the heat dissipation hole 302. Through the opening of the annular groove 301, a larger heat dissipation space is provided for the inside of the connector body 1. When the connector body 1 is working, the generated heat will be quickly conducted to the annular groove 301. The setting of the heat dissipation hole 302 and the heat dissipation groove 303 provides a heat dissipation channel, and the heat in the annular groove 301 is discharged through the heat dissipation hole 302, and then dissipated to the external environment through the heat dissipation groove 303. This design effectively reduces the temperature inside the connector body 1 and ensures the normal operation of the connector body 1.

[0039] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, a locking thread 4 is provided at one end of the connector body 1, and the locking thread 4 is located on one side of the dustproof pad 201, and one end of the locking thread 4 is located on one side of the bevel 204. The locking thread 4 is located at one end of the connector body 1, adjacent to the bevel 204 of the dustproof pad 201. When the connector body 1 is connected to other devices, the locking thread 4 can ensure the tightness and stability of the connection. At the same time, since the locking thread 4 is located on one side of the bevel 204, when the connector body 1 is rotationally locked, the design of the bevel 204 can further enhance the sealing of the dustproof pad 201 and the connector body 1, thereby improving the waterproof and dustproof effects.

[0040] like Figure 2 and Figure 6As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a dustproof rubber cover 5 is clamped on one side of the connector body 1, and clamping columns 9 are arranged on both sides of the dustproof rubber cover 5. One end of the clamping column 9 is clamped on one side of the connector body 1, and the dustproof rubber cover 5 is located on one side of the heat dissipation groove 303. The dustproof rubber cover 5 is clamped with one side of the connector body 1 through the clamping column 9 and is located on one side of the heat dissipation groove 303. When the connector body 1 is not in use, the dustproof rubber cover 5 can cover the heat dissipation groove 303 and the air outlet groove 6 to prevent dust and moisture from entering the interior of the connector body 1. At the same time, the dustproof rubber cover 5 also has a certain sealing performance, which can further improve the waterproof and dustproof effect of the connector body 1.

[0041] like Figure 5 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, an air outlet slot 6 is opened on one side of the connector body 1, one end of the air outlet slot 6 is tilted downward, the interior of the air outlet slot 6 is connected with the interior of the heat dissipation slot 303, the air outlet slot 6 is located on one side of the dustproof rubber cover 5, the air outlet slot 6 is located on one side of the dustproof rubber cover 5, one end of the air outlet slot 6 is tilted downward and connected with the interior of the heat dissipation slot 303, when the connector body 1 is working, the hot air in the heat dissipation slot 303 will naturally rise and be discharged into the external environment through the air outlet slot 6, and the downward tilted design of the air outlet slot 6 helps to guide the flow direction of the hot air and improve the heat dissipation efficiency.

[0042] like Figure 2 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a connecting pin 7 is provided on one side of the connector body 1, and one end of the connecting pin 7 is bent downward by 90°. The connecting pin 7 is located on one side of the connector body 1, and one end is bent downward by 90°. This design enables the connecting pin 7 to be directly inserted into a matching socket or device to achieve a fast and stable electrical connection. At the same time, the downward bending design of the connecting pin 7 can also effectively avoid the risk of accidental touch or short circuit.

[0043] like Figure 5 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the bottom end of the connector body 1 is provided with a fixing tooth 8 for fixing the connector body 1. The fixing tooth 8 is located at the bottom end of the connector body 1 and is used to fix the connector body 1. By cooperating with the circuit board on which the connector body 1 is installed, the fixing tooth 8 can firmly install the connector body 1 in the designated position. This design not only improves the stability of the connector body 1, but also helps to protect the connector body 1 and the equipment connected thereto from external shocks and vibrations.

[0044] Specifically, when the explosion-proof electrical connector with waterproof and dustproof effects is working: the setting of the dustproof pad 201 effectively blocks the entry of external dust and impurities; the middle groove 202, the triangular groove 203 and the oblique groove 204 on the dustproof pad 201 not only enhance the dustproof effect, but also guide the dust to the outside through the inclined design of the oblique groove 204, further keeping the inside of the connector body 1 clean; in addition, the dustproof rubber cover 5 is fixed to the connector body 1 through the clamping column 9, covering the heat dissipation groove 303 and the air outlet groove 6, providing additional dustproof and waterproof protection for the connector body 1; secondly, the internal design of the connector body 1 ensures efficient heat dissipation; the annular groove 301 provides sufficient heat dissipation space for heat; the heat is discharged through the heat dissipation hole 302 and dissipated to the external environment along the heat dissipation groove 303; the design of the air outlet groove 6 makes the heat dissipation groove 30 3 can be discharged smoothly, and one end of it is tilted downward to help guide the flow direction of the hot air, thereby improving the heat dissipation efficiency. Again, a locking thread 4 is set at one end of the connector body 1, and the tight connection between the connector body 1 and other devices can be ensured by rotating the locking thread 4. One end of the locking thread 4 is located on one side of the inclined groove 204, which enhances the sealing of the dustproof pad 201 and further improves the waterproof and dustproof effect. At the same time, a connecting pin 7 is set on one side of the connector body 1, and one end of it is bent downward by 90°, which is convenient for fast and stable electrical connection with the matching equipment. Finally, a fixing tooth 8 is set at the bottom end of the connector body 1, allowing the connector body 1 to be firmly installed in the specified position, whether it is on a mounting plate, bracket or other fixing device, the stability of the connector body 1 can be ensured.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
