[0018] The utility model will be further described below in combination with the drawings and the embodiments.

[0019] In the description of the utility model, it is understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0020] Referring to Figures 3 to 6The embodiment discloses a vehicle-mounted camera, which comprises a vehicle-mounted camera rear cover 1, a shell 2, a circuit board 3, a coaxial connector 4, a sealing ring 5 and a lens 6. The lens is installed on the shell 2. The circuit board 3 is located in a cavity formed by the vehicle-mounted camera rear cover 1 and the shell 2 and is electrically connected with the coaxial connector 4. The coaxial connector 4 is riveted and fixed with the vehicle-mounted camera rear cover 1 and is sealed by sealing glue (not shown).

[0021] In the embodiment, the vehicle-mounted camera rear cover 1 is provided with a mounting hole for mounting the coaxial connector 4. The mounting hole comprises a pouring hole 6 and a riveting hole 7. The pouring hole 6 is communicated with the riveting hole 7. The diameter of the riveting hole 7 is smaller than that of the pouring hole 6. The bottom surface of the pouring hole 6 is provided with a plurality of grooves 8. The grooves 8 are communicated with the riveting hole 7.

[0022] One end of the coaxial connector 4 is provided with a boss 9. The boss 9 is arranged in the pouring hole 6. There is a gap between the boss 9 and the side wall of the pouring hole 6 for the sealing glue to flow. The coaxial connector 4 is in interference fit with the riveting hole 7. The sealing glue is injected into the pouring hole 6. The sealing glue fills the pouring hole 6, the grooves 8 and the riveting hole 7. By arranging the grooves 8 communicated with the riveting hole 7 on the bottom surface of the pouring hole 6, the sealing glue in the pouring hole 6 can smoothly fill the gap between the coaxial connector 4 and the vehicle-mounted camera rear cover 1. The cavity between the coaxial connector 4 and the vehicle-mounted camera rear cover 1 cannot be filled with the sealing glue, thereby avoiding the false leakage phenomenon caused by the bubbles in the air tightness test of the vehicle-mounted camera.

[0023] It should be noted that the sealing ring 5 is installed in the vehicle-mounted camera in the embodiment. However, the sealing ring 5 is not necessary. In other embodiments, the vehicle-mounted camera can also not be installed with the sealing ring 5. The overall structure of the coaxial connector 4 shown in the drawing of the embodiment is circular. In other embodiments, the coaxial connector 4 is not limited to this, for example, the coaxial connector 4 can also be square or irregular. The shape of the mounting hole is matched with the coaxial connector 4.

[0024] If the intersection part 15 of the groove 8 and the riveting hole 7 is a right-angled corner, the inflow of the sealing glue into the riveting hole 7 can be hindered due to the too small gap. Preferably, at least the intersection part 15 of the groove 8 and the riveting hole 7 is chamfered or rounded, so as to increase the flow space of the sealing glue and make the sealing glue sufficiently flow into the riveting hole to fill the recesses on the outer surface of the coaxial connector 4. In the embodiment, the edges of the riveting hole 7 close to one end of the pouring hole 6 are chamfered, which is convenient for manufacturing.

[0025] The pouring hole 6 can be a single hole or a composite hole composed of two or more holes. The pouring hole 6 shown in the embodiment is a stepped hole with a large upper part and a small lower part.

[0026] The number of the grooves 814 can be one or more. When the number of the grooves 814 is more than two, preferably, each groove 814 is uniformly distributed along the periphery of the second hole 12, so that the sealant is uniformly filled into the second hole 12. When the number of the grooves 814 is more than two, each groove 814 can be of the same shape or of different shapes.

[0027] The shape of the groove 814 can be various, for example, the groove 814 can be of the same width from top to bottom, or the groove 814 can be of a large width from top to bottom or of a small width from top to bottom. The horizontal ends of the groove 814 can be of the same size or of different sizes. Preferably, the groove 814 is smoothly connected with the bottom of the potting hole 6, so that the sealant can flow into the groove 814.

[0028] The above description is only used to illustrate the technical solutions of the present application, but not to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalent features. These modifications or replacements do not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the present application. Therefore, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.
