Description

Technical Field

[0001] The utility model relates to the technical field of connector components, and particularly relates to a charging lamp with high stability. Background Art

[0002] Due to the special working nature of the vehicle during driving, the internal components of an electric vehicle have extremely high stability requirements, especially some important components such as connectors. Conventional connectors, such as the charging connector disclosed in Publication No. CN 115693270 A, usually do not have corresponding lighting settings on their flange plates, but this is not convenient for observation and maintenance during daily use.

[0003] On the other hand, there are often gaps between the internal bulbs and the housings of existing charging indicators, which may cause collisions after being jolted, resulting in damage to the indicators. During the driving of an electric vehicle, jolts are inevitable. Conventional charging lamps do not have special stability structures inside, making it easy for the charging lamps to collide with the housings due to jolts, resulting in damage or failure, or even causing the housing to crack, and the fragments generated by the cracked housing may damage other components.

[0004] Therefore, an indicator with high stability is needed. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a charging lamp with high stability.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0026] Such as Figures 1 to 5As shown in the figure, the present utility model discloses a charging lamp with high stability, which includes a housing and a PCB board 2 and a connector 3 disposed inside the housing. A light source 4 is provided on the PCB board 2. The connector 3 is fixedly connected to the PCB board 2 and extends outward from the lower housing 102. It is characterized in that: the housing includes a mating upper housing 101 and a lower housing 102. The outer contour of the PCB board 2 matches the inner contour of the housing and is located between the upper housing 101 and the lower housing 102. A first limiting post 103 perpendicular to the front end face of the PCB board 2 is fixedly provided on the inner wall of the upper housing 101. The first limiting post 103 abuts against the front end face of the PCB board 2 and forms a limit on the PCB board 2 in the vertical direction; two corners located on the same diagonal line inside the lower housing 102 are provided with second limiting posts 104 perpendicular to the rear end face of the PCB board 2. Through holes 201 are correspondingly provided at the corners of the PCB board 2. The second limiting posts 104 are inserted into the through holes 201 to form a limit on the PCB board 2 in the horizontal direction.

[0027] In this application, the housing is formed by splicing the upper housing 101 and the lower housing 102, and the PCB board 2 is disposed between the upper housing 101 and the lower housing 102. The upper housing 101 forms a vertical limit on the PCB board 2 through the internally provided first limiting post 103, and the lower housing 102 forms a horizontal limit on the PCB board 2 through the second limiting post 104.

[0028] Specifically, racks 109 that can be engaged are respectively provided at the edges of the upper housing 101 and the lower housing 102. The edges of the upper housing 101 and the lower housing 102 are engaged through the racks 109, and the racks 109 are integrally formed by ultrasonic welding. Such a connection method can make the upper housing 101 and the lower housing 102 be tightly connected into one body. Of course, in other feasible embodiments, other feasible fixing methods can also be adopted between the upper housing 101 and the lower housing 102, such as bonding, etc.

[0029] Connection holes 110 are symmetrically provided on both sides of the lower housing 102, and fastening screws are inserted into the connection holes 110 to facilitate connection with other components.

The lamp cover 105 protrudes from the outer surface of the upper shell 101. When the charging lamp is installed on other components (not shown in the figure), the lamp cover 105 can be embedded and exposed on the surface of other components to facilitate the light emitted by the light source 4 from being blocked.

[0032] Preferably, the light sources 4 are arranged in pairs opposite to each other to form a rectangle, and the lamp cover 105 is a shape matching the outer contour of a group of the light sources 4. In other feasible embodiments, the number of the light sources 4 is not limited to 4, and the light sources 4 can be arranged in other feasible shapes, such as a triangle, a circle, etc. The lamp cover 105 matches the arrangement shape of the light sources 4 to best transmit the light of the light sources 4.
