Abstract
The invention discloses a short-circuit electrical connector in a piston. The short-circuit electrical connector consists of a plug and a socket. The plug is arranged in a piston rod and jointed with the socket, and consists of a shell, an insulating sleeve, an insulating fixed seat, an annular inner conductor A and an annular inner conductor B, wherein the insulating fixed seat is arranged at a corresponding position in the shell; the annular inner conductor A, the annular inner conductor B and the insulating sleeve are sequentially sleeved between the head of the insulating fixed seat and the shell; and annular grooves for accommodating socket contact parts are formed between the annular inner conductors A and B at a jointing end. The socket contact parts adopt cable needle contact parts with drum-shaped convex hulls at jointing ends. The short-circuit electrical connector has a small volume, and is convenient to plug, weak in plugging and unplugging force and reliable in contact.
Description
Technical field
The present invention relates to use the short circuit connector in a kind of piston, belong to technical field of electric connectors.
Background technology
The short circuit connector is meant in plug or socket end and carries out short circuit (connecting with lead etc.) to contact that plug together the back and realize electrically conducting, generally speaking, it is easier that short circuit connector is installed, and uses screw to get final product.If but be used for the short circuit connector of piston, promptly short circuit connector one end is installed in the piston, install to connect then relatively difficulty, because of piston diameter less; Can't use screw to install, can only adopt threaded engagement to install, promptly in plug or socket tail end machining screw; But use screw thread to install, make contact not have accurate position again, and mounting panel is rotating around central shaft in the piston; Do not have the fixed position yet, plug together to connector and bring very big difficulty (depart from if having, damage connector contact easily); And installation is guide locating device provided between plugs and sockets, can increase installing space again, is unfavorable for the miniaturization requirement of product.
Summary of the invention
The objective of the invention is provides a kind of interior short circuit connector of using of piston of being convenient to connection to the problems referred to above.
Use the short circuit electric connector in the said piston; Form by plugs and sockets; Wherein plug places in the piston rod, the socket and plug butt joint, and said plug is made up of housing 4, insulating case, insulation holder, annular inner wire A and annular inner wire B; Said insulation holder places relevant position in the housing; Annular inner wire A, annular inner wire B and insulating case are set between the head and housing of insulator holder successively, and annular inner wire A, annular inner wire B lower end do not have the gap contact and connect, and are provided with the cannelure that holds the socket contact between the butt end.
Said socket contact is the fried dough twist needle contact piece, promptly forms with elastic wire is hinged, and there is the contact of cydariform convex closure the butt end.
Adopt the beneficial effect of technique scheme to be: volume is little, plugs together conveniently, and contact engaging and separating force is little, and contact is reliable.

Embodiment
Below in conjunction with the accompanying drawing instance the present invention is done further explain:
As shown in the figure; Short circuit connector according to the invention is made up of plug and socket; Said plug is made up of housing 4, insulating case 3, insulation holder 5, annular inner wire A and annular inner wire B; Said insulation holder 5 places relevant position in the housing 4; Annular inner wire A, annular inner wire B and insulating case 3 are set between the head and housing 4 of insulator holder 5 successively, and annular inner wire A, annular inner wire B lower end do not have the gap contact and connect, and are provided with the cannelure 6 that holds socket contact 7 between the annular inner wire A of butt end, the annular inner wire B.Said socket contact 7 adopts the fried dough twist needle contact piece, promptly forms with elastic wire is hinged, and there is the contact of cydariform convex closure the butt end, the slotting contact engaging and separating force when reducing to dock.
During installation; Plug places in the piston 10 with after patch bay 9 is connected, and in the piston of patch bay 9 bottoms spring is housed; Plug can be in piston 10 rotates and moves axially around central shaft; Socket is connected with socket mounting panel 8, because of the socket contact adopts the fried dough twist needle construction, can realize that under the effect of spring force plugs and sockets plugs together;
Connector plug of the present invention is worked in piston; Its installation and plug together before all do not have fixed position (plug pivots with mounting panel) in piston; But plugging together contact point with socket is cannelure, and therefore contact arbitrarily and reliably, contact engaging and separating force is lower; Under the effect of spring force, just can realize plugging together, have many characteristics a short circuit.
What the accompanying drawing illustrated embodiment adopted is two annular inner wires, realizes two pairs of contact short circuits, during actual the use, can also expand according to operating position, adopts a plurality of annular inner wire suits to connect, and realizes a plurality of contact short circuits.
In sum, the present invention has following characteristics:
1, plug changes connector form in the past, uses ring channel structures, does not re-use guider and leads and locate, and when plugging together, plug pivots and takes office where to plugging together smoothly with the socket end connector;
2, socket connector uses the fried dough twist pin, and contact engaging and separating force is lower, and plug can plug together under the effect of spring force;
3, can realize simultaneously many connector being carried out short circuit, reduce small product size.
Claims (2)
1. use the short circuit electric connector in a piston; Form by plugs and sockets; Wherein plug places in the piston rod; The socket and plug butt joint; It is characterized in that: said plug is made up of housing 4, insulating case 3, insulation holder 5, annular inner wire A (1) and annular inner wire B (2), and said insulation holder 5 places relevant position in the housing 4, and annular inner wire A (1), annular inner wire B (2) and insulating case 3 are set between the head and housing 4 of insulator holder 5 successively; Annular inner wire A (1), annular inner wire B (2) lower end do not have the gap contact and connect, and are provided with the cannelure (6) that holds socket contact (7) between the annular inner wire A (1) of butt end, the annular inner wire B (2).
