Description
Technical Field
The utility model belongs to the technical field of the resistance technique and specifically relates to a spring resistor.
Background
In the technical field of spring resistance, the ends of the spring resistance wire are connected with a conductive wiring board through welding and other forms after the two ends of the spring resistance wire penetrate through a mica plate, but the connection mode is easy to cause falling off or the conductivity of the resistance wire is changed, so that the use is influenced.
Like chinese utility model patent, 201720865598.X, a protective wiring end, its both ends with spring resistance wire set up the ring to push down it through elastic pressing plate, inside wears to establish the bolt and carries on spacingly, but in the in-service use process, because the bolt only has three rings of threads with being connected of clamp plate, still less, causes the bolt not hard up easily, influences normal performance. In addition, the device has complex structure and high cost.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve above-mentioned technique not enough and provide a spring resistance, the tip of its spring resistance wire is stable with the firm in connection of electrically conductive wiring board on the mica plate.
The utility model discloses a spring resistance, including mica plate, spring resistance wire, the mica plate is provided with two through-holes, the diameter of through-hole is greater than the external diameter of spring resistance wire, has cup jointed the mica plate at spring resistance wire's both ends, is provided with a conductive wiring board on every mica plate, on the tip of spring resistance wire extended to the conductive wiring board that corresponds the side, be provided with the clamp plate on conductive wiring board, the tip of the spring resistance wire on the conductive wiring board was located between conductive wiring board and the clamp plate, all was provided with corresponding screw on clamp plate, conductive wiring board, the mica plate of spring resistance wire tip both sides, wears to be equipped with the bolt in the screw to as an organic whole clamp plate, conductive wiring board, mica plate fixed connection through the nut, the tip of conductive wiring board is used for connecting wire.
In the above scheme, the mica plate is provided with the through hole, and the diameter of the through hole is larger than the outer diameter of the spring resistance wire, and the through hole and the spring resistance wire are the best when the through hole and the spring resistance wire are consistent. After the spring resistance wire passed the through-hole, its tip extended to on the electrically conductive wiring board that is located the mica plate side, and carry out the pressfitting through the clamp plate, electrically conductive wiring board, carry out fastening connection through bolt and nut between the mica plate, and the bolt distributes in the both sides of spring resistance wire, so the connection to the tip of spring resistance wire is more firm stable, and the tip of spring resistance wire is by whole centre gripping between clamp plate and electrically conductive wiring board, so can increase the area of contact of spring resistance wire and electrically conductive wiring board, increase its electric conductive property.
The end part of the conductive wiring board, which is not connected with the lead, extends to the range of the outermost circle of the spring resistance wire. The design of this structure, will electrically conductive wiring board extends to the spiral within range of spring resistance wire, can effectively restrict the tip of spring resistance wire in the through-hole of the mica plate that corresponds, avoids because of the tensile circumstances such as the tip that causes the spring resistance wire drops from between clamp plate and the electrically conductive wiring board, promotes the fastness of its connection and the performance of equipment.
An arc-shaped groove is formed in the middle of the pressing plate, and the end portion of the spring resistance wire is located in the range of the arc-shaped groove. The design of this structure, its clamp plate also adopt electrically conductive material, can with the complete pressfitting of the tip of spring resistance wire between clamp plate and electrically conductive wiring board, can further promote the area of contact of clamp plate, electrically conductive wiring board and spring resistance wire tip, promote electric conductive property and stability.
The utility model provides a spring resistance, it is through reasonable structural design, can effectively promote firm in connection nature and area of contact between the electrically conductive wiring board on spring resistance wire and the both ends mica plate to promote electric conductive property and stability.
