Abstract
The invention discloses an underwater pluggable explosion-proof electric connection terminal structure. The underwater pluggable explosion-proof electric connection terminal structure consists of a female terminal and a male terminal. When the male terminal is not plugged into the female terminal, a cylindrical waterproof spring (11) isolates an electrified internal contact (10) from the outside; when the male terminal is plugged into the female terminal, the male terminal compresses the cylindrical waterproof spring (11) to deform by using a head (1); liquid and gas inside the female terminal flow out from a U-shaped groove (2); the male terminal is continuously plugged, a rubber block (6) and an insulator (4) at the tail of the male terminal are firmly combined, and the interior of a cavity of the female terminal is isolated from the exterior of the cavity; subsequently, a movable contact (9), an internal contact (10) and the head (1) of the male terminal are connected together; a clamping spring (8) of the female terminal clamps a neck (3) of the male terminal, and the male terminal and the female terminal are fixed at the relative positions; the separation process of the male terminal and the female terminal is opposite to the process.
Description
Technical field
The present invention relates to electric connection structure design and devdlop technical field, specifically provide a kind of underwater pluggable flame-proof type electric connecting terminal minor structure.
Background technology
Splicing ear can be divided into four classes according to the difference of using method under water: stem grafting is inserted/use type under water, wet patches/use type under water, patched/use type under water, under water hot insertion/use type under water under water.At present, the research of China to underwater pluggable electric connector relatively lags behind, the most dependence on import of underwater pluggable electric connector product of domestic use.
Summary of the invention
The object of this invention is to provide the underwater pluggable flame-proof type electric connecting terminal minor structure of a kind of dependable performance, low cost.
A kind of underwater pluggable flame-proof type electric connecting terminal minor structure of the present invention, be made up of female terminal and male terminal two large divisions, central scope is: when female terminal does not have male terminal to access, and tubular waterproof spring (11) is charged inner contact (10) and external isolation; When male terminal inserts female terminal, male terminal head (1) compresses tubular waterproof spring (11) is out of shape; Liquid, the gas of female terminal inside first flow out from " U " shape groove (2); Male terminal continues to insert, and block rubber (6) and male terminal afterbody insulator (4) are combined closely, in female terminal chamber and the external isolation of chamber; Subsequently, armature contact (9), inner contact (10), male terminal head (1) are bonded together; Female terminal jump ring (8) blocks male terminal neck (1), and male terminal, female terminal relative position are fixed; When male terminal, female terminal are separated in contrast.
Accompanying drawing explanation
Fig. 1 is underwater pluggable flame-proof type electric connecting terminal minor structure sectional drawing; In figure: (1) head, (2) " U " shape guiding gutter, (3) neck, (4) afterbody, (5) male terminal shell; (6) rubber isolation part, (7) shape annular protrusion and annular ditch, (8) jump ring fixed part, (9) armature contact, (10) armature contact, (11) tubular waterproof spring, (12) insulator, (13) buffer spring, (14) terminal shell.
