Abstract

The invention discloses a high-resistance chip resistor, which comprises an inner shell of the chip resistor and a circuit board lower plate arranged on the inner shell of the chip resistor. The front and rear sides of the inner shell of the chip resistor are respectively sleeved with Two side protective shells, the left and right sides of the inner shell of the chip resistor are respectively provided with two side inner frames, the inner shell of the chip resistor is provided with a chip guide groove, and the horizontal inner chute plate Slidingly connected with the axial sliding rod. In the present invention, an oblique guide rod limit connection structure is adopted to realize stable control of the contact area and contact effect during the abutment process between the two transverse inner chute plates and the inner shell of the chip resistor, and at the same time It is easy to use when disconnecting and replacing. It adopts a push-type locking dust-proof protection structure, which realizes that when the dust-proof upper cover plate and the side protection shell are close to each other, the two side protection shells are pushed close to each other and pressed tightly, thus realizing the protection of chip resistors. The inner shell of the device is sealed and installed.

Description

technical field [0001] The present invention relates to the technical field of resistor devices, in particular to a high-resistance chip resistor. Background technique [0002] Resistors are generally called resistors in daily life. They are current-limiting components. After connecting the resistors in the circuit, the resistance of the resistors is fixed. Generally, there are two pins, which can limit the branch through which it is connected. The magnitude of the current that cannot be changed is called a fixed resistor, and the variable resistance is called a potentiometer or a variable resistor. The ideal resistor is linear, that is, the instantaneous current passing through the resistor is proportional to the applied instantaneous voltage. Proportional, variable resistor for voltage division, one or two movable metal contacts are pressed tightly on the exposed resistor body, and the contact position determines the resistance value between either end of the resistor body...
