Abstract

The utility model relates to a bead type quick plugging connector, which comprises a plug part and a socket part, wherein the plug part includes a plug casing (1), a pin type inner conductor (2) and a first insulated support member (3); the socket part includes a socket casing (4), a hole type inner conductor (5) and a second insulated support member (6). The bead type quick plugging connector is characterized in that an elastic contact part (9) is embedded in the plug casing; the elastic contact part (9) is provided with a plurality of elastic pieces (91) which extend forwards and are arranged at intervals along a circumference; a gas (X) for the socket casing (4) to be plugged in is disposed between the periphery of the elastic pieces (91) and the inner wall of the plug casing (1); and when the socket casing (4) and the plug casing (1) are in insertion joint state, the elastic pieces (91) contact with the inner wall of the socket casing (4). By means of the factor that the elastic pieces at the front end of the elastic contact part contact with the inner wall of the socket casing, the bead type quick plugging connector leads the plug casing to be securely connected with the socket casing, and relative shaking is not easily caused, accordingly the pin type inner conductor is guaranteed to effectively contact with the hole type inner conductor.

Description

A kind of pearl formula quick plug connector

Technical field

The utility model belongs to technical field of electric connectors, relates in particular to a kind of pearl formula quick plug connector.

Background technology

Fast development along with mechanics of communication, equipment volume such as various the army and the people's microwave communications, mobile communication, fine measuring instrument are tending towards miniaturization, microminiaturization day by day, the connector that causes being used for these equipment need carry out socket in very intensive space, and will guarantee reliable in structure.At present a large amount of screw thread couplings that use or fast socket, connector be to after inserting, and pin connector and socket connector are connected by screw thread or special retaining mechanism, and axiality requires high, and axis tilt relatively, and installation makes things convenient for inadequately.

Pearl formula quick plug connector is just developed under this condition, and it is primarily aimed at high-density installation, and it has reliable connection, and advantage rapidly is installed.As a patent No. is a kind of radio-frequency (RF) coaxial electric connector so the Chinese utility model patent " a kind of radio-frequency (RF) coaxial electric connector " of ZL200720123127.8 (notification number is CN201113056Y) has disclosed, constitute by plug portion and socket part, the excircle of this electrical connector plug shell mating side partly is provided with equally distributed bellmouth, be provided with ball in the described bellmouth, the shell circumference also is provided with overcoat outward simultaneously, ball corresponding position in described overcoat and the bellmouth is provided with projection, overcoat is formed corresponding enclosed cavity with the shell other end, in this cavity, be provided with spring, be enclosed within outward under the effect of spring, but opposite shell moves axially; Socket shell excircle corresponding position partly is provided with boss and groove, by ball on the plug and cooperating of socket convex platform and groove realizing fast plugging and locking.

Electric connector in the aforementioned patent at plug body with after jack housing is connected, only depend between the two that the elasticity coupling mechanism force locks together between the effect of ball and overcoat and contact pin and the jack, therefore the connection power between plug body and the jack housing not enough, plug body and jack housing easily axially break away from, and cause between contact pin and the jack easily loosening.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of plug body that can make to be connected firm pearl formula quick plug connector with jack housing at above-mentioned prior art present situation, guarantees that the pin type inner wire well contacts with the cellular type inner wire.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of pearl formula quick plug connector comprises plug portion and socket part; Plug portion comprises plug body, pin type inner wire and first insulation support body; Socket part comprises jack housing, cellular type inner wire and second insulation support body; The outer peripheral face upper edge circle spacing of described plug body inserted terminal is provided with a plurality of bellmouths, is provided with ball in this bellmouth, and the outer peripheral face of described jack housing Plug Division is provided with the groove that snaps in for ball; Described plug body outside also is arranged with the lock tube of separating of the relative plug body axial slip of energy, and this is separated the lock tube inwall and has the lug boss that cooperates with described ball and the pearl groove that falls; Described separating between lock tube inwall and the plug body periphery wall also forms an enclosed cavity, is provided with in this cavity separating and acts on the spring of separating lock tube under the lock tube slip state; It is characterized in that: also be embedded with resilient contact in the described plug body, the flexure strip that this resilient contact has a plurality of extensions forward and is provided with along the circle spacing, has the gap of inserting between this flexure strip periphery and the plug body inwall for jack housing, under the state that jack housing and plug body plug together, contact between described flexure strip and the jack housing inwall.

Above-mentioned flexure strip head end has the protruding salient point of side.This salient point the Elastic Contact power that can increase between flexure strip and the jack housing inwall is set.

Separate lock tube for ease of operation, the above-mentioned lock tube periphery of separating has coarse reticulate pattern portion.Reticulate pattern portion can increase the feel that lock tube is separated in promotion.

Be the convenient reticulate pattern portion that processes, the above-mentioned lock tube periphery of separating also has two ringwise grooves, and these two grooves are arranged on the both sides of reticulate pattern portion.

Above-mentioned plug body periphery has the convex annular shoulder, the also sheathed retaining ring that is fixed with of plug body periphery, described retaining ring, convex annular shoulder and separate the cavity that the lock tube inwall surrounds described putting spring.This structure is convenient to form cavity separating between lock tube and the plug body.

Above-mentioned spring has two, described separate lock tube inwall middle part ringwise in omoplate, should be positioned at described enclosed cavity by interior omoplate, wherein a spring is supported between convex annular shoulder and the interior omoplate, another root spring is supported between retaining ring and the interior omoplate, the described pearl groove that falls has two, lays respectively at the both sides of described lug boss.Two springs are set can realize plugging together and all can provide a corresponding axial force when separating, cooperate two pearl grooves that fall again separating lock tube, so just can about promote to separate lock tube, realize removing to the locking of ball to jack housing, be convenient to operation.

Compared with prior art, advantage of the present utility model is: this connector is set up a resilient contact in plug body, by Elastic Contact between resilient contact front end flexure strip and the jack housing inwall, it is firm that plug body is connected with jack housing, be difficult for rocking relatively, thereby guarantee that the pin type inner wire well contacts with the cellular type inner wire.
