The utility model relates to starter relay, and particularly a kind of starter contact prevents adhesion electromagnetic switch.
Background technology
Traditional starter relay comprises shell, be located at the insulating base of outer casing bottom, be located at two fixed contacts in insulating base, be fixed on the annular brace limit base above insulating base, be arranged in the movable contact rod at annular brace limit base center, be fixed on movable contact rod lower end and be the movable contact spring of 90 degree of angles with movable contact rod, be located at the back-moving spring between movable contact rod lower end and insulating base bottom surface, be set in the sleeve of annular brace limit base upper periphery, be located at the solenoid in annular space that sleeve and shell formed, to be located in sleeve and to utilize spring supporting in the dynamic iron core at annular brace limit base top, wherein, movable contact spring is the double contact structure of a control flow check through starter armature electric current, movable contact spring two ends are corresponding two fixed contacts respectively.When solenoid charging, dynamic iron core moves down, thus drive movable contact rod and movable contact spring to move down, movable contact spring two ends are connected with two fixed contacts On current respectively, but there are the following problems for it: 1, often cause the contact site of movable contact spring two ends and two fixed contacts to melt owing to flowing through big current, cause contact adhesion; 2, because this contact is double contact structure, so be difficult to after being sticked together be disconnected by the elastic force of back-moving spring, cause switch to scrap, starter burns.
Summary of the invention
The purpose of this utility model is to provide a kind of reasonable in design, safe and reliable starter contact solved the problem to prevent adhesion electromagnetic switch.
The technical solution of the utility model is:
A kind of starter contact prevents adhesion electromagnetic switch, comprise shell, be located at the insulating base of outer casing bottom, be located at two fixed contacts in insulating base, be fixed on the annular brace limit base above insulating base, be arranged in the movable contact rod at annular brace limit base center, be located at movable contact rod lower end and be the movable contact spring of 90 degree of angles with movable contact rod, be located at the back-moving spring between movable contact rod lower end and insulating base bottom surface, be set in the sleeve of annular brace limit base upper periphery, be located at the solenoid in annular space that sleeve and shell formed, to be located in sleeve and to utilize support spring to be supported in the dynamic iron core at annular brace limit base top, it is characterized in that: in the middle part of described movable contact spring, utilize rotating shaft hinged with movable contact rod, separately wire is connected with between described movable contact spring one end and corresponding fixed contact.
Above-mentioned starter contact prevents adhesion electromagnetic switch, and described wire is that superfine proof copper-wire braided forms copper wire pigtail.
Above-mentioned starter contact prevents adhesion electromagnetic switch, and described wire one end is connected to movable contact spring end and avoids movable contact spring and fixed contact top phase contact near rotating shaft side, and the other end is connected to fixed contact side and avoids fixed contact top and movable contact spring phase contact.
Above-mentioned starter contact prevents adhesion electromagnetic switch, offers the through hole of corresponding movable contact rod in the middle part of described movable contact spring, and described movable contact rod to be inserted in this through hole and hinged with movable contact spring.
Above-mentioned starter contact prevents adhesion electromagnetic switch, and the lower central position of described annular brace limit base is provided with limit chamber, and the corresponding limit chamber position of described movable contact rod is provided with annular stop boss.
Above-mentioned starter contact prevents adhesion electromagnetic switch, the central upper portion position of described annular brace limit base is provided with annular groove base, described dynamic mandrel bottom center is provided with the groove identical with annular groove base outside dimension, described support spring is located between annular groove base bottom surface and groove floor, and described groove floor center is separately provided with the push rod of corresponding movable contact rod.
Above-mentioned starter contact prevents adhesion electromagnetic switch, described shell lower end utilizes seam to be fixed together in insulating base upper edge and annular brace limit base lower surface, and insulating base upper edge is built-in with the rubber washer contacted with annular brace limit base lower surface.
The beneficial effects of the utility model are: compared with traditional double terminal contacts structure, structure does not need through excessive change, on original double contact structure basis, just do two places change: 1, movable contact spring one terminal contacts is connected with wire in advance with corresponding fixed contact, due to this wire to there is conducting moment two ends, contact electromotive force equal, this contact, side not easily comes in contact the spark of moment, and due to the shunting action of wire, the electric current flowing through this contact is also less, then this contact, side not easily occurs to melt adhesion; 2, only have one not with copper wire pigtail in two contacts easily to stick together, when single contact sticks together, movable contact spring can produce the motion deflected around the shaft under the return tractive effort effect of movable contact rod, this athletic meeting forms a lever at the position of contact adhesion, because adhesion point is fulcrum and resistance arm, and the movable contact spring other end can produce one close to infinitely-great power at this point, can " break " in the contact sticked together by this infinitely-great power very easily.Thus electromagnetic switch is normally used, extend the useful life of electromagnetic switch.
