Embodiment Construction

[0014] The present invention is described in detail below in conjunction with accompanying drawing example:

[0015] Such as figure 1 As shown, the rubber-sealed electrical connector of the present invention is composed of a contact piece 1, a housing 4, and a base 5. The contact piece 1 and the base 5 are installed in the housing 4, and the outer edge of the base 5 is provided with a step There is an annular groove 5a, and there is an annular groove 4c corresponding to the step in the inner hole of the shell. When installing the base, first apply the sealant 6 (silicone rubber) to the annular groove 5a of the base, and then put it into the shell. Also when installing the contact piece 1, the sealant is applied first and then put into the base, so that the connected cavity formed by the annular groove 5a of the base, the shell step, and the annular groove 4c of the inner hole of the shell is sealed by the sealant 6, and the tail end shell 4 The sealing structure glue 2 is pou...

Abstract

The invention discloses a glue-sealed type electric connector which consists of a contact element, an outer shell and a pedestal; the contact element and the pedestal are arranged inside the outer shell; the step of the outer edge of the pedestal is provided with an annular groove; the corresponding location of the step of the inner bore of the outer shell is provided with an annular seal groove; after the pedestal is arranged in the outer shell, a communicated cavity formed by the annular groove of the pedestal, the step of the outer shell, the annular groove of the inner bore of the outer shell is injected with seal gum; the seal gum is also injected between the contact element and the pedestal, and is further injected among the internal cavity of the outer shell at the tail end of the connector, the pedestal and the contact element. The glue-sealed type electric connector has the advantages of simple structure and good sealing property, thus avoiding the problems caused by the inconsistent heat expansion coefficients of various seal gum and effectively reducing the dimension of the butt-joint direction of the connector.

Description

technical field [0001] The invention relates to a non-glass-sealed glue-sealed electrical connector, which belongs to the technical field of sealed electrical connectors. Background technique [0002] General rubber-sealed electrical connectors (hereinafter referred to as products) are generally provided with multiple annular ribs and grooves in the glue-filling cavity at the end of the product, and are sealed and prevented by potting multi-layer sealants (commonly known as insulators). Base) out of the shell, such as in 200720123196.9 "the socket end adopts a three-layer sealant structure, which are primer, sealant, and sealant structure", but this structure lengthens the dimension in the docking direction. In addition, Due to the inconsistent thermal expansion coefficients of different sealants, especially the hardening of the sealant at low temperature often leads to the failure of the sealing function of the product. Moreover, the amount of sealant used in potting is rel...
