Description

Technical Field

[0001] The utility model relates to the technical field of resistors, in particular to a resistor with flanks and capable of current diversion. Background Art

[0002] In electronic circuits, resistors are widely used for functions such as regulating current, limiting current, voltage division and current shunting.

[0003] At present, the common resistor structure is a linear resistor, which is characterized by a stable resistance value. However, in some occasions, the resistor cannot be shunted. In view of this, we propose a shunted resistor with flanks. Utility Model Content

[0004] The utility model aims to solve the problem that the resistor in the prior art cannot shunt the resistor, and proposes a shuntable resistor with flanks.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A resistor with flanks and current diversion, comprising an insulating shell, a current diverter resistor installed in the insulating shell, and the current diverter resistor comprising a plurality of resistor bodies;

[0007] Electrode 1 is connected in parallel between the head ends of several resistors, a circuit switch is provided between electrode 1 and the head end of the resistor, movable guide frames are installed around the peripheries of several resistors, and electrode 2 is connected in parallel between the ends of several movable guide frames.

[0008] Preferably, a plurality of the resistors are arranged in a straight line and at equal intervals, the resistors are in a ring shape, and the ends of the electrode 1 and the electrode 2 both pass through the insulating shell.

[0009] Preferably, the lower end of the electrode one is connected to a shunt guide rod one, the lower end of the electrode two is connected to a shunt guide rod two, and the ends of the shunt guide rod two are respectively connected to the ends of a plurality of the movable guide frames.

[0010] Preferably, a knob is provided at the end of the movable guide frame, and the knob passes through the insulating shell.

[0011] Preferably, the circuit switch comprises a moving contact, and the moving contact is mounted on the head end of the resistor.

[0012] Preferably, an inner thread guide block is connected to the periphery of the moving contact, an adjusting screw is provided in the inner thread guide block, and the adjusting screw is connected to the insulating housing.

[0013] Compared with the prior art, the utility model provides a resistor with flanks and divertable current, which has the following beneficial effects:

[0014] 1. The resistance values ​​of the two resistor bodies in the resistor with flank diverter can be adjusted by manually rotating the knob to drive the movable guide frame to rotate along the resistor body, thereby changing the length of the connected resistor body and thus changing the resistance value of the resistor body, thereby realizing the adjustable function of the resistor value.

[0015] 2. The resistor with flank shunt connects the circuit in the flank shunt resistor body through a circuit switch, and guides the main resistor current from one side of the resistor body to the other side, thereby realizing the shunt function of the resistor. When shunting is required, it is only necessary to connect the current to the flank shunt resistor body to make the current bypass a part of the main resistor, thereby achieving the shunting effect and improving the flexibility of the circuit and the freedom of layout.

[0021] Reference Figure 1-2A resistor with side wings and diverterable current includes an insulating shell 1 for protecting the internal structure of the resistor. In the present application, the insulating shell 1 is divided into two layers, an inner layer and an outer layer. The inner layer is made of insulating ceramic with high thermal conductivity to avoid electrical contact between the resistor and other circuit elements. The outer layer is made of stainless steel with high mechanical strength. The inner layer of insulating ceramic and the outer layer of stainless steel are tightly fitted. Both the insulating ceramic and the stainless steel are made of good thermal conductors to provide good heat dissipation effects.

[0022] In this embodiment, a shunt resistor is installed in the insulating shell 1. The shunt resistor includes a plurality of resistor bodies 8. The resistor bodies 8 are fixedly installed in the insulating shell 1. In this application, the specific number of resistor bodies 8 used is two. The two resistor bodies 8 are arranged in a straight line and equidistantly. One resistor body 8 acts as a main resistor, and the other resistor body 8 acts as a wing shunt resistor. The wing shunt resistor 8 functions to guide the main resistor current from one side of the resistor body 8 to the other side, thereby realizing the shunt function of the resistor. When shunting is required, it is only necessary to connect the current to the wing shunt resistor 8 so that the current can bypass a part of the main resistor to achieve the shunting effect. The resistor body 8 is in a ring shape, and the two ends are not connected. An electrode 2 is connected in parallel between the head ends of the two resistor bodies 8, and a circuit switch is provided between the electrode 2 and the head end of the resistor body 8. Movable guide frames 6 are installed on the periphery of the two resistor bodies 8, and an electrode 2 3 is connected in parallel between the ends of the two movable guide frames 6.

[0023] In this embodiment, the end of the movable guide frame 6 is arranged on the central axis of the ring-shaped resistor 8, the movable guide frame 6 is rotatably connected to the insulating shell 1, the end side of the movable guide frame 6 is fixedly connected with a knob 7, the head end of the movable guide frame 6 is slidably connected to the resistor 8, the knob 7 passes through the insulating shell 1, the electrode 1 2 and the electrode 2 3 are fixedly connected to the insulating shell 1, and the top ends of the electrode 1 2 and the electrode 2 3 pass through the insulating shell 1.

[0024] In this embodiment, the lower end of electrode 1 2 is fixedly connected with a forked shunt guide rod 1 4, and the lower end of electrode 2 3 is fixedly connected with a forked shunt guide rod 2 5. The ends of shunt guide rod 2 5 are respectively rotatably connected with the ends of several movable guide frames 6. The circuit switch includes a moving contact 9. The shunt guide rod 1 4, the shunt guide rod 2 5, the movable guide frame 6, and the moving contact 9 are all made of brass with small resistance. The moving contact 9 is slidably installed on the head end of the resistor 8. The periphery of the moving contact 9 is fixedly connected with an internal thread guide block 10. The internal thread guide block 10 is internally threaded with an adjusting screw 11, and the adjusting screw 11 is rotatably connected to the insulating shell 1.

[0025] In the utility model, in an electronic circuit, when the resistor with flank shunt is used, it is first connected to electrode 1 2 and electrode 2 3 as needed through a wire, and then the circuit in the resistor body 8 of the flank shunt is disconnected through two circuit switches, and the circuit in the resistor body 8 of the main resistor is connected, so that the main resistor is mainly used, and the resistance values ​​of the two resistor bodies 8 can be manually rotated by the knob 7 to drive the movable guide frame 6 to rotate along the resistor body 8, change the length of the connected resistor body 8, thereby changing the resistance value of the resistor body 8, and realizing the adjustable function of the resistor resistance value, and then the circuit in the resistor body 8 of the flank shunt is connected again through the circuit switch, and the main resistor current is guided from one side of the resistor body 8 to the other side, thereby realizing the shunt function of the resistor, and when shunting is required, it is only necessary to connect the current to the resistor body 8 of the flank shunt, so that the current can bypass a part of the main resistor, achieve the shunting effect, and improve the flexibility of the circuit and the freedom of layout.

[0026] It should be added that the switching of the above-mentioned circuit switch is specifically implemented as follows: by manually rotating the adjusting screw 11, the threaded internal thread guide block 10 is driven to pull the moving contact 9 to move along the head end of the resistor body 8, separating or squeezing the end of the contact shunt guide rod 4, thereby realizing the opening and closing of the circuit in the resistor body 8. The switching action of the circuit switch and the rotation action of the movable guide frame 6 in the above-mentioned application are both manually operated, and can also be used through electrical components such as electric push cylinders and motors to automatically realize the shunt function of the resistor and the adjustable resistance value of the resistor.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
