Technical Field

[0001] The utility model relates to the field of pulse resistors, in particular to a pulse discharge resistor component. Background Art

[0002] Pulse discharge resistors are a type of high-power power source that is widely used in people's daily lives. The traditional way to fix pulse discharge resistors is to use screws, including screw-tightening block type and ring screw-tightening type. The use of screws for fastening and fixing can easily lead to inconsistent contact surface pressure and uneven contact surface load on the surface of the fixed end resistor, which may increase the loss of the resistor and cause energy waste. In order to install the resistor securely, the screws usually need to be tightened with greater force, which may cause damage to the surface of the resistor and affect the normal working life of the resistor. In addition, the installation method of the screws requires contact with other tools, which is not convenient. The screws may have rusted during disassembly and need to be disassembled with the help of other devices.

[0024] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0026] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figure 1 and Figure 2 As shown, the pulse discharge resistor assembly designed in the present application includes a pulse discharge resistor 3 and two elastic conductive brackets, and the pulse discharge resistor 3 is installed between the two elastic conductive brackets; the elastic conductive bracket includes an elastic conductive folding ear 2 and a resistor bracket sleeve 1 arranged on the elastic conductive folding ear 2. The elastic conductive folding ear 2 has a first folded edge and a second folded edge connected to each other, the first folded edge is connected to the resistor bracket sleeve 1, and the second folded edge is provided with a plurality of mounting holes 5. The resistor bracket sleeve 1 is a hollow conical sleeve structure, one end of the resistor bracket sleeve 1 is connected to the elastic conductive folding ear 2, and the other end of the resistor bracket sleeve 1 is matched with the end of the pulse discharge resistor 3, and an inward inclination angle β is provided, the inclination angle β is 1° to 2°, and the preferred inclination angle β is 1.5°. The design of the inclination angle is conducive to the resistor bracket sleeve 1 clamping the pulse discharge resistor 3, and the sleeve-type connection method has better electrical connection performance than the screw connection.

[0028] like Figure 6As shown, at least two milling grooves 6 perpendicular to the bottom edge of the conical sleeve are evenly opened on the conical surface of the resistor bracket sleeve 1, which facilitates the installation and insertion process of the pulse discharge resistor 3 while maintaining the strength of the resistor bracket sleeve 1. The preferred number of milling grooves 6 is 5. At the same time, in order to ensure that the resistor bracket sleeve 1 has good opening and closing capabilities, the length of the milling groove 6 is at least 1 / 2 of the length of the conical sleeve. Both ends of the pulse discharge resistor 3 are partially inserted into the resistor bracket sleeve 1, and the insertion depth is 1 / 2 to 2 / 3 of the length of the resistor bracket sleeve 1. When installing or removing the pulse discharge resistor 3, the elastic conductive bracket needs to be bent outward. When the insertion depth is too deep, the bending angle needs to be larger. Although the conductive bracket is made of elastic material, bending at too large an angle should be avoided. Too deep an insertion depth is not conducive to the installation and removal of the pulse discharge resistor 3. If the insertion depth is too shallow, the pulse discharge resistor 3 may be unstable after placement and may fall.

[0029] like Figure 3 and Figure 4 As shown, in some embodiments, a circular sleeve hole 4 is formed on the elastic conductive folding ear 2, and one end of the resistor bracket sleeve 1 is connected to the circular sleeve hole 4. The resistor bracket sleeve 1 is a hollow conical sleeve structure, and the middle is still a hollow structure after the elastic conductive folding ear 2 is connected. The hollow structure has a good ventilation effect, is not easy to accumulate dust, and is helpful for heat dissipation of the pulse discharge resistor component during operation, and is not easy to cause excessive local heat at the contact end to burn the component.

[0030] like Figure 5 As shown, in some embodiments, the elastic conductive folded ear 2 has a first folded edge and a second folded edge connected to each other, the first folded edge is connected to the resistor bracket sleeve 1, and the second folded edge is provided with a plurality of mounting holes 5. The folded edge with the mounting hole 5 can be set to face outward or inward, and the user can choose to install it in the forward or reverse direction according to the actual installation environment. Although the elastic conductive folded ear 2 shown in the accompanying drawings is bent at a right angle, the accompanying drawings only show one embodiment of the embodiment. The actual bending angle of the elastic conductive folded ear 2 does not need to be strictly 90°. The specific bending angle is adjusted according to the actual installation environment, and can be adjusted to an obtuse angle or an acute angle on the premise of stable installation.

[0031] like Figure 6 As shown, in some embodiments, the resistor bracket sleeve 1 includes a first sleeve and a second sleeve, and the first sleeve cooperates with the pulse discharge resistor 3. To facilitate the insertion of the pulse discharge resistor 3, a smooth round chamfer is provided at the round mouth of the first sleeve, and only a small force is required to insert it smoothly during installation. One end of the second sleeve is connected to the first sleeve, and the other end of the second sleeve is connected to the circular sleeve hole, and the second sleeve is smaller than the first sleeve. For easy installation, the inner side of the second sleeve is a regular hexagonal structure, and the outer side of the second sleeve is provided with a thread that cooperates with the circular sleeve hole 4, which can fit tightly.

[0032] In some embodiments, two resistor bracket sleeves 1 are arranged on one elastic conductive folding ear 2, and two pulse discharge resistors 3 can be installed on one elastic conductive folding ear 2 at the same time. When setting the distance between the two resistor bracket sleeves 1, the moving space required for installing the pulse discharge resistor 3 should be fully considered. Under the premise of satisfying the electrical connection performance and mechanical strength performance, according to actual needs, three, four or more resistor bracket sleeves 1 can also be arranged on one elastic conductive folding ear 2.

[0033] Installation method of pulse discharge resistor assembly:

[0034] Install the resistor bracket sleeve 1 in the circular sleeve hole 4 of the elastic conductive folding ear 2 to assemble into an elastic conductive bracket, install two elastic conductive brackets symmetrically in the target area, and reserve the installation distance for installing the pulse discharge resistor 3. The actual distance is determined by the length of the pulse discharge resistor 3 and the depth of the pulse discharge resistor 3 inserted into the resistor bracket sleeve 1. Insert one end of the pulse discharge resistor 3 into the bottom of one of the resistor bracket sleeves 1, align the other end of the pulse discharge resistor 3 with the other opposite resistor bracket sleeve 1, bend the elastic conductive bracket outward at a certain angle, and insert the other end of the pulse discharge resistor 3 into the resistor bracket sleeve 1. Adjust both ends of the pulse discharge resistor 3 to be inserted into the 1 / 2 to 2 / 3 depth of the resistor bracket sleeve 1.

[0035] The embodiments of the present invention are described in detail above, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
