Description

Waterproof light guide ring of electronic product socket

Technical Field

The utility model relates to an assembly structure of electronic product socket.

Background

In order to facilitate the use of the vehicle interior personnel in a dark environment, many vehicle-mounted electronic product sockets (including but not limited to a TYPE-a USB socket, a TYPE-C USB socket, an AUX socket, etc.) require a ring-shaped backlight. Taking a USB socket as an example, in order to achieve the backlight effect, as shown in fig. 1 and fig. 2, the most commonly used scheme is to install the vehicle-mounted USB socket 9 into the annular light guide ring 8, since the light guide ring 8 and the vehicle-mounted USB socket 9 are both rigid structures, a gap g is easily formed between the light guide ring 8 and the vehicle-mounted USB socket 9 due to processing or assembly errors, and when water splashes on the surface of a product, the water easily permeates into the PCBA circuit board in the vehicle-mounted USB socket from the gap between the light guide ring 8 and the vehicle-mounted USB socket 9, and further, short circuits of components on the PCBA circuit board may be caused, which may cause a functional failure of the.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Please refer to fig. 3 to 6. According to the utility model discloses a waterproof light guide of electronic product socket includes rigid light guide body 1 and elastic waterproof circle 2.

The light guide ring body 1 is provided with a central through hole 10, the top of the central through hole 10 is provided with a countersunk section 10a, the countersunk section comprises a small hole section 102 and a large hole section 101 positioned above the small hole section 101, and a step surface 103 is formed between the large hole section 101 and the small hole section 102.

Waterproof circle 2 is pressed on step face 103, and waterproof circle 2 and light guide ring body 1 are through two material integrated into one piece that mould plastics.

In this embodiment, the bottom of waterproof circle 2 is equipped with a plurality of downwardly extending's projection 24, and the step face 103 of light guide ring body 1 is equipped with respectively with a plurality of recesses 104 of a plurality of projections 24 one-to-one, during a plurality of projections 24 imbed a plurality of recesses 104 respectively, so, both can combine together more closely after moulding plastics. In other embodiments, a convex pillar protruding upwards may be disposed on the step surface 103 of the light guide ring body 1, and a groove matching with the convex pillar of the light guide ring body 1 may be disposed at the bottom of the waterproof ring 2, and the convex pillar and the groove are in concave-convex matching. The shape of the protruding column 24 may be rectangular, cylindrical, truncated cone, etc., and the present invention is not limited thereto.

Further, the top surface of the waterproof ring 2 is flush with the top surface of the light guide ring body 1.

Further, the central through hole 20 of the waterproof ring 2 is gradually enlarged from the mouth portion to the bottom portion, and the shape is beneficial to the closer contact between the orifice portion of the central through hole of the waterproof ring 2 and the socket of the electronic product, so that a more reliable sealing effect is obtained.
