Lower seat of connector

Abstract

The invention discloses a lower seat of a connector. The lower seat comprises a shell, two compression conductive elastic sheets, a grounding reed and an insulating fixing ring, wherein the two compression conductive elastic sheets are connected with a positive electrode and a negative electrode of an external power supply; the grounding reed is connected with a grounding electrode of the external power supply; the shell is in opposite socket connection with the insulating fixing ring; the fixing ring is provided with an insulating connecting chord; the middle part of the insulating connecting chord is provided with a fixing ring water separation walls; the grounding reed is arranged on the back face of the insulating connecting chord between the fixing ring water separation walls; and the two compression conductive elastic sheets are spaced apart from each other by the insulating ring water separation walls and are arranged on the front face of the insulating connecting chord. Since the compression conductive elastic sheets and the grounding reed are arranged on the front face and the reverse face of the fixing ring insulating connecting chord respectively, complete isolation between the compression conductive elastic sheets and the grounding reed is realized, and in such a case, even if liquid enters the lower seat of the connector, a conductive path cannot be formed between the conductive component and the grounding component, and the given creepage distance cannot be shortened, so that a product can be used for a long time without worry.

Description

technical field [0001] The present invention relates to an electrical connector, in particular to a lower seat of a connector of an electric heater. Background technique [0002] The existing connectors for electric heaters generally include an upper connector base and a lower connector base, and the connection between the upper connector base and the lower connector base is generally divided into two types. One of them is: the spring-supported elastomeric seal is used to formally seal the entrance of the lower seat of the connector to prevent the liquid from entering during the use of electrical appliances by the user, but when the user actually uses it, the electrical coupling of the upper seat of the connector The elastomer seal of the connector lower seat is directly pressed into the connector. During this process, the electrical coupling can be completely pressed into the connector lower seat together with the liquid adhered to the surface, resulting in the accumulation...

Problems solved by technology

One of them is: the spring-supported elastomeric seal is used to formally seal the entrance of the lower seat of the connector to prevent the liquid from entering during the use of electrical appliances by the user, but when the user actually uses it, the electrical coupling of the upper seat of the connector It is to directly press the elastomer seal of the connector lower seat into the connector. During this process, the electrical coupling can be completely pressed into the connector lower seat together with the liquid adhered to the surface, resulting in the accumulation of liquid in the connector lower seat. , resulting in the danger of short-circuiting the circuit, but it cannot achieve the purpose of real waterproofing

The other type does not use the above elastomer seal, but relies on the wide drain hole in the lower seat of the connector to discharge the liquid, but the conductive parts and grounding parts of this type of connector are often fixed on the same side of the lower seat of the connector. When the liquid enters the drainage channel of the connector lower seat, due to its own tension, it will partially adhere to the conductive parts and plastic parts, and the conductive parts and the grounding parts are installed on the same side of the connector lower seat, so no real isolation is achieved. After the electrical appliance is used for a long time, it is easy to cause the creepage distance between the conductive part and the grounding part to shrink, and the leakage on the surface of the insulating material will cause tracking. After the creepage distance is further shortened, the circuit will be short-circuited, and there is a fire hazard.
