technical field

The utility model relates to a signal connector which utilizes a tapered part to guide water stains to prevent short circuits, in particular to setting a longitudinal tapered part and a plurality of transverse tapered parts on an insulating base to pass through the longitudinal tapered part. part divides the connecting terminals on the insulating base body into multiple rows, and separates the same row and adjacent connecting terminals through the transverse tapered part, so that the external water stains will not cause the The connection terminals are short-circuited.

Background technique

Signal connector (Connector) generally refers to the connection components and accessories used in electronic signals and power supplies. It is a bridge for all signals. Its quality will affect the reliability of current and signal transmission. It is compatible with various electronic systems and electrical The operation of the equipment is closely related. At present, various electrical equipment (such as: home appliances, smart phones, industrial servers, etc.) are equipped with signal connectors to receive power or data, although the electrical equipment is covered with a casing to prevent dust and water The air comes into contact with the precision electronic components inside, but since the signal connector is mostly assembled on the electrical equipment in a non-watertight manner, if the user uses the electrical equipment in humid weather, the external moisture and moisture will pass through The gap in the signal connector invades the interior of the electrical equipment, causing the precision electronic components in the electrical equipment to be short-circuited or corroded due to contact with water or moisture. Therefore, in recent years, waterproofing for signal connectors Design has become a market demand that cannot be ignored.

Generally speaking, the most critical part of the waterproof design of the signal connector is the connection terminal, because the connection terminal is mostly assembled in the connector in the form of inserting, so in the past, the industry often needed to dispensing the connection terminal. Using waterproof glue Seal the insertion gap of the connecting terminal. However, this method can only ensure the waterproofness of the "inside" of the signal connector, and has not considered the "outside" of the signal connector. Please refer to Figure 1. Now, an existing Technical signal connector description: The signal connector 1 includes an insulating base body 11 and a plurality of connecting terminals 12, the connecting terminals 12 are embedded in the insulating base body 11, and according to the requirements of waterproof performance, the industry will insulate The inside of the base body 11 is coated with waterproof glue to seal the gap between the middle section of the connecting terminal 12 and the inner wall of the insulating base body 11 .

According to the above, although the gap between the connection terminal 12 and the inner wall of the insulating base 11 can be formed into a watertight state by waterproof glue, when the electrical equipment used by the signal connector 1 is used outdoors, once the signal connector 1 1 is wetted by water, the remaining water stains on the top surface of the insulating base 11 can easily cause a short circuit between the connecting terminals 12, resulting in damage to electrical equipment. Therefore, the creator considers whether a simple structure can be designed to solve the problem of short circuit between the connecting terminals 12 caused by water damage without greatly affecting the production cost of the signal connector 1 . Therefore, how to improve the structure of the signal connector 1 in the prior art to enhance its waterproof performance has become an important issue to be solved by the present invention.
