Description

Technical Field

[0001] This utility model relates to the field of resistor technology, and in particular to an S-shaped resistor structure that is easy to fix and install. Background Technology

[0002] The resistance of a conductor is the opposition it makes to the flow of electric current. Resistance is a physical quantity that, in physics, represents the magnitude of a conductor's opposition to the flow of electric current. The greater the resistance of a conductor, the greater its opposition to the flow of current. Different conductors generally have different resistances; resistance is an intrinsic property of the conductor itself.

[0003] Traditional cement resistors or color-coded resistors, according to existing technology (CN202310017718.0), often require a large product size for impact resistance. Furthermore, the insulation and heat resistance of the resistor body are limited by the coating and body size, and installation is inconvenient. Due to different installation environments, the required accessories also vary, and the structure may need to be replaced.

[0004] Therefore, it is necessary to design an S-shaped resistor structure that is easy to fix and install to solve the above problems. Utility Model Content

The ceramic shell is square in shape, with grooves inside for mounting the resistor module. A partition is placed within the grooves, dividing them into S-shaped slots. L-shaped slots are formed at one set of diagonal points on the ceramic shell for bolt fixing. Protrusions are provided outwards at another set of diagonal points on the ceramic shell. An arc-shaped groove is formed at the midpoint of the upper and lower surfaces of the ceramic shell. The resistor module includes several resistors arranged in an S-shape connected end-to-end, and connecting pieces that connect the resistors in series.

[0008] Preferably, the resistor includes a resistance rod, a resistance winding wound around the resistance rod, and end caps respectively installed at both ends of the resistance rod; the two ends of the resistance winding are respectively welded to the end caps at both ends.

[0009] Preferably, the resistor is provided with at least three groups of first resistor, second resistor and third resistor, which are arranged in parallel and sequentially from top to bottom; the end cap of the first end of the first resistor is welded with a long terminal, which is arranged to extend outward, the end cap between the tail end of the first resistor and the tail end of the second resistor is welded with a connecting piece; the end cap between the head end of the second resistor and the head end of the third resistor is welded with a connecting piece, and the end cap of the tail end of the third resistor is welded with a long terminal, which is arranged to extend outward.

[0010] Preferably, the connecting piece is in T-shaped structure.

[0011] The beneficial effects of the utility model are that: the technical scheme sets multiple structures suitable for installation in different situations on the ceramic shell, sets the resistors in S-shaped structure in series in the inside, is small in space, and is large in power, maximizes the space utilization, and has large power for use, and increases the impact resistance of the product in the circuit.
