Description
Technical field
The utility model relates to a kind of bench vehicle type electrical resistance furnace electrical contact jockey.
Background technology
Traditional heating resistor of bench vehicle type electrical resistance furnace chassis and the connected mode of external circuit (as shown in Figure 1) are: chassis moving contact is made flat contract type (being processed into pointed before flat cuboid), the fixed contact of body of heater is made crotch type, and outside clamps with opening jump ring.Moving contact is contained on movable chassis, and fixed contact is contained on the lower furnace wall of stove afterbody.When work, movable chassis is filled needs the material of annealing to move in stove, and moving contact is arranged on chassis, and chassis is connected with the fixed contact being arranged on body of heater with moving contact, and moving contact and the fixed contact indication circuit that connects together is communicated with.Energising just can be carried out annealing work.This connected mode can well be used in the time of new stove, when bench vehicle type electrical resistance furnace used after a period of time, because annealing process at high temperature carries out, the environment for use of moving contact and fixed contact is quite severe, moving contact and fixed contact are just easy to distortion after at high temperature using repeatedly, moving contact can not well be contacted with fixed contact, affect the transmission of electric current.Chassis and material to be annealed have several tons of weights in addition, when mobile, inertia is also large, be easy to fixed contact to rush open, cause fixed contact opening very large, moving contact and just more bad connection of fixed contact, need artificial going to repair, again because temperature in stove is high like this, need cooling to repair, cause very large waste.
Summary of the invention
The above-mentioned shortcoming existing in order to overcome the heating resistor of existing bench vehicle type electrical resistance furnace chassis and the connected mode of external circuit, the utility model provides a kind of bench vehicle type electrical resistance furnace electrical contact jockey.
The technical solution adopted in the utility model is:
Bench vehicle type electrical resistance furnace electrical contact jockey, comprise and be arranged on the moving contact on movable chassis and be arranged on the fixed contact on body of heater, it is characterized in that: described moving contact is constituted by the first cylindrical section, conical section and the first hemisphere, one end that described moving contact is connected with chassis is the first described cylindrical section, the rear end of the first described cylindrical section is conical section, the end end of described conical section is the first hemisphere, and the first described hemispheroidal sphere and the taper seat of conical section are tangent;
Described fixed contact is constituted by the second cylindrical section and three cylindrical section, and the front end of the second described cylindrical section is described three cylindrical section, and the floor space of described three cylindrical section is greater than the floor space of the second described cylindrical section; The opening that is provided with foremost indent of described three cylindrical section, shape and the size of the conical section on described opening and described moving contact and the combination of the first hemisphere are suitable.
Further, the shape of described opening is made up of internal conical surface and the second hemisphere, described internal conical surface and described the second hemisphere respectively with described moving contact on conical section and the first hemispheroidal shape and size suitable.
Further, the floor space of described conical section is greater than the floor space of the first described cylindrical section.
Further, the gradient of described conical section is 2～5 degree.
Further, the outer surface sheathed of the first described cylindrical section plays the stainless steel spring of cushioning effect when contacting with chassis.
Further, the outer surface sheathed of the second described cylindrical section is for playing the stainless steel spring of cushioning effect.
The beneficial effects of the utility model are embodied in: the contact area that has increased moving contact and fixed contact, and sphere and sphere-contact, even if trolley movement track has deviation also can ensure that moving contact well inserts fixed contact, also more slotting tighter in the taper seat of conical section on moving contact on insertion fixed contact time, even because high temperature moving contact also can ensure good contact with fixed contact distortion.
