Abstract
The utility model relates to an electrical connector used in a low temperature environment. The electrical connector used in the low temperature environment comprises a metal casing, wherein the metal casing is convexly provided with a fixed disc along a radial direction, the fixed disc is used for stopping and matching with a corresponding mounting panel, the metal casing is sleeved with a sealing washer which is used for being squeezed between the fixed disc and the metal casing when the electrical connector is mounted on the corresponding mounting panel, and the sealing washer is a solid and soft metal washer. When the electrical connector is mounted on the corresponding mounting panel, the sealing washer is squeezed and deformed, and is respectively glued between the fixed disc on the metal casing and the mounting panel through two sides so as to realize sealing of a matched portion of the electrical connector and the mounting panel; the sealing washer is the solid and soft metal washer, so a problem of turning hard and brittle does not occur in the low temperature environment, and a problem that an electrical connector in the prior art can not be used in the low temperature environment further required to be in sealing fit with the mounting panel is solved.
Description
Technical field
The utility model relates to electric connector field, especially a kind of electric connector that is used for low temperature environment.
Background technology
Existing electric connector mostly comprises metal shell; Has radially protruding fixed disk on the outside wall surface of metal shell; Said fixed disk is used for after metal shell inserts the installing hole of corresponding installation panel, cooperating with the installation panel block, thereby electric connector fixedly is assembled on the corresponding installation panel; Often in the coaxial rubber seal that is arranged with in a side place that fixed disk is used for cooperating with the installation panel block, rubber seal then is the hermetically-sealed construction of the cooperation place between electric connector and the installation panel on the metal shell.The hermetically-sealed construction of above-mentioned electric connector all can satisfy seal request in most of occasions; Yet, at some special occasions, in environment such as liquid hydrogen; The working temperature of electric connector is extremely low; Therefore rubber seal in low temperature environment very easily hardening become fragile, can't realize sealing function, this then makes existing electric connector can't be applied in the environment that low temperature and requirement and installation panel is sealed and matched.
Summary of the invention
The purpose of the utility model is to provide a kind of electric connector that is used for low temperature environment, to solve the problem in the environment that existing electric connector can not be applicable to that low temperature and requirement and installation panel is sealed and matched.
In order to address the above problem; The electric connector of the utility model adopts following technical scheme: the electric connector that is used for low temperature environment; Comprise metal shell; Radially convex with on the said metal shell and be used for the fixed disk that cooperates with corresponding installation panel block, be arranged with on the metal shell and be used for when this electric connector is assembled on the corresponding installation panel by the seal washer of jam-packed between fixed disk and metal decking, said seal washer is a solid soft metal packing ring.
The position that is used for the jam-packed seal washer of said fixed disk is provided with and supplies seal washer to be extruded the accepting groove that the distortion back embeds, and said accepting groove is around metal shell.
Said accepting groove is a V-shaped groove.
Said seal washer is aluminium packing ring or copper washer.
Said fixed disk is provided with bolt connecting hole.
Said bolt connecting hole is a counterbore.
Because the electric connector that is used for low temperature environment of the utility model is used for when this electric connector is assembled on the corresponding installation panel by the seal washer of jam-packed between fixed disk and metal decking being arranged with on its metal shell, and said seal washer is a solid soft metal packing ring; Therefore; When the electric connector with the utility model is assembled on the corresponding installation panel; Seal washer is extruded distortion and fits respectively and between fixed disk on the metal shell and the installation panel through both sides; Thereby realize the sealing of the cooperation place of electric connector and installation panel; Because described seal washer is solid soft metal packing ring, the problem that does not therefore exist the low temperature hardening to become fragile, thus solved the problem in the environment that existing electric connector can not be applicable to that low temperature and requirement and installation panel is sealed and matched.
Description of drawings
Fig. 1 is the structural representation (removing seal washer) of embodiment 1 of the electric connector that is used for low temperature environment of the utility model;
Fig. 2 is the enlarged drawing of Fig. 1 at the A place;
Fig. 3 is the user mode figure of embodiment 1 of the electric connector that is used for low temperature environment of the utility model.
Embodiment
The embodiment 1 of the electric connector that is used for low temperature environment of the utility model shown in Fig. 1-3, comprises metal shell 1; Metal shell 1 is cylindrical; It is provided with radially protruding fixed disk 2 in outer peripheral face, and fixed disk 2 is provided with bolt connecting hole 3, and this bolt connecting hole 3 is a counterbore; Be arranged with seal washer 4 on the metal shell 1, seal washer 4 employings fixedly soft metal (like soft aluminium, red copper etc.) are made, and after being squeezed, can producing corresponding plastic deformation and not influenced by low temperature environment; Seal washer 4 is used in the present embodiment electric connector when loading onto corresponding installation panel 5 by jam-packed between fixed disk 2 and installation panel 5 and deformation takes place, thus being sealed and matched between realization electric connector and the installation panel 5; In addition; If the crush seal packing ring is realized sealing when only depending on electric connector to install; The plane roughness of the extruding pretightning force when then electric connector being installed, fixed disk and seal washer packing ring bound fraction all has higher requirement; Therefore the electric connector in the present embodiment is provided with the accepting groove 6 around metal shell in the position that is used for the crush seal packing ring of its fixed disk, and accepting groove 6 is a V-shaped groove, and promptly its cross section is a V-arrangement; Thereby can supply seal washer to get into, realize the sealing between electric connector and the installation panel in the back that is squeezed and deforms.
In the time of on described electric connector being assembled to corresponding installation panel; At first the end with the metal shell of said electric connector inserts in the installing hole on the installation panel; Said fixed disk cooperates with a side block of installation panel and seal washer is limited between fixed disk and the installation panel; The bolt connecting hole that pass fixed disk on through screw this moment fixedly is assemblied in metal shell on the installation panel, and in the process that screw is screwed, said seal washer is by jam-packed and plastic deformation takes place; Seal washer fills up accepting groove in the process of distortion, thereby realizes the sealing between electric connector and the installation panel.
In other embodiment of the electric connector that is used for low temperature environment of the utility model; Bolt connecting hole on the fixed disk described in the foregoing description 1 can also omit; In such cases; Corresponding locking nut can be set on metal shell during installation, metal shell is lock onto on the installation panel, perhaps metal shell fixedly press-fited on installation panel through pressing plate; Said accepting groove can also be U-lag or rectangular channel, and the quantity of accepting groove can also be for more than two; Accepting groove can also omit.
