Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the technical field of shunts, and in particular, to a protection tooling for a shunt. Background Art
[0002] A shunt is an instrument for measuring direct current. It is made based on the principle that when a direct current passes through a resistor, a voltage is generated across the resistor. In essence, a shunt is usually a precision resistor at the mΩ level. The more accurate the resistance value, the more accurate the measured current.

At the same time, the heat dissipation effect of the shunt is not ideal. When the temperature is too high, it is easy to cause the shunt to interrupt working, affecting the measurement time, thus reducing the utilization efficiency of the shunt. Utility Model Content

[0027] To facilitate the understanding of the technical solutions of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.
[0028] First of all, it should be noted that the protection tooling of the embodiments of the present application can be applied to shunts or other devices, and the present application does not limit this.
[0029] The embodiments of the present application provide a protection tooling for a shunt. Figure 1 It is a three-dimensional schematic diagram of the protection tooling in some embodiments of the present application. Figure 2 It is a three-dimensional schematic diagram of the heat dissipation mechanism in some embodiments of the present application. As Figure 1 、 Figure 2As shown in the figure, the protection tooling for the shunt includes a shunt 1. Insulating protection plates 2 are provided on the left and right sides of the shunt 1. A chute 3 is provided on the inner surface of the insulating protection plate 2. A copper bar 4 is slidably installed inside the chute 3. One end of the copper bar 4 is fixedly connected to one end of the shunt 1. Insulating support plates 5 are provided on both the upper and lower surfaces of the copper bar 4. The insulating support plates 5 are fixedly installed on one side surface of the insulating protection plate 2. A heat dissipation mechanism 6 is provided above the surface of the shunt 1. An anti-deformation mechanism 7 is fixedly installed on the outer surface of the insulating protection plate 2. The heat dissipation mechanism 6 includes a mounting component installed on the upper surface of the insulating protection plate 2. One end of the mounting component is clamped with a heat dissipation component. The anti-deformation mechanism 7 includes an anti-deformation component located on the outer surface of the insulating protection plate 2. A buffer component is provided on the outer surface of the anti-deformation component. The mounting component includes a mounting base 61 installed on the upper surface of the insulating protection plate 2. A clamping block 62 is clamped inside the mounting base 61. A connecting arm 63 is fixedly installed on the upper surface of the clamping block 62. The heat dissipation component includes a fan base 64 installed at one end of the connecting arm 63. One end of the connecting arm 63 is inserted into the inside of the fan base 64. A heat dissipation plate 65 is clamped on the surface of the fan base 64. A diversion groove is provided on the surface of the heat dissipation plate 65. Condensing beads 66 are fixedly installed on the inner wall surface of the diversion groove.
[0030] In the technical solution of the embodiment of the present application, the large current of the shunt 1 is transferred through the processed copper bar 4. The chute 3 for fixing the copper bar has a certain installation adjustability, and the assembly can be completed for shunts of different sizes of 75A / 100A. At the same time, through the clamping block 62, it is clamped and installed inside the mounting base 61. Similarly, by using the connecting arm 63, it is clamped inside the fan base 64 for assembly. Then, through the air group inside the fan base 64, the heat dissipated by the shunt 1 is absorbed. The airflow direction of the heat is upward. Through the diversion groove provided on the surface of the heat dissipation plate 65, the heat is absorbed and dissipated by the condensing beads 66. At the same time, an open structure is adopted for heat dissipation, which can take into account the heat dissipation problem of large current.
[0031] According to some other embodiments of the present application, as Figure 3 shown, the anti-deformation component includes a mounting plate 71 installed on the outer surface of the insulating protection plate 2. A reinforcing plate 72 is clamped inside the mounting plate 71. A fixing seat 73 is fixedly installed on the surface of the reinforcing plate 72. A buffer sleeve 74 is fixedly installed inside the fixing seat 73. One end of the buffer sleeve 74 is fixedly installed with a buffer plate 75. An elastic block 76 is fixedly installed on the back surface of the buffer plate 75.
[0032] In the technical solution of this embodiment, the reinforcing plate 72 is snap-fitted inside the mounting plate 71 and set in two groups. Then, it is mounted on the surface of the reinforcing plate 72, and the elastic block 76 is used to strengthen the protection of the insulating protection plate 2. At the same time, through the buffer sleeve 74, when a collision occurs, it uses its own elasticity to buffer. Then, through the buffer plate 75, while extruding it, deformation occurs, thereby improving the buffer effect.
[0033] According to some other embodiments of the present application, as Figure 4 shown, a compression member 741 is movably installed inside the buffer sleeve 74.

A buffer rod 745 is movably connected inside the buffer 744, and the buffer rod 745 is located below the compression member 741.
[0034] In the technical solution of this embodiment, when the elastic block 76 collides, it drives the compression member 741 to be extruded into the buffer sleeve 74 and squeezes the buffer rod 745. The buffer rod 745 drives the buffer 744 to press down, thereby driving the extrusion plate 743 to extrude. The buffer springs 742 are compressed and rebound and buffer through their own elasticity, effectively improving the buffer effect.
[0035] Next, specifically describe the working principle of the protection tooling of the shunt.
[0036] As Figure 1 shown in -4, first, the large current of the shunt 1 is transferred through the processed copper row 4. The chute 3 for fixing the copper row has a certain installation adjustability, and the assembly of shunts of different sizes of 75A / 100A can be completed. At the same time, through the snap block 62, it is snap-fitted and installed inside the installation base 61. Similarly, using the connecting arm 63, it is snap-fitted inside the fan base 64 for assembly. Then, through the air group inside the fan base 64, the heat dissipated by the shunt 1 is absorbed. The airflow direction of the heat is upward. Through the diversion groove opened on the surface of the heat dissipation plate 65, the heat is absorbed and dissipated by the condensation beads 66. At the same time, the open structure is used for heat dissipation, which can take into account the heat dissipation problem of large current. Then, the reinforcing plate 72 is snap-fitted inside the mounting plate 71 and set in two groups. Then, it is mounted on the surface of the reinforcing plate 72, and the elastic block 76 is used to strengthen the protection of the insulating protection plate 2. At the same time, through the buffer sleeve 74, when a collision occurs, it uses its own elasticity to buffer. Then, through the buffer plate 75, while extruding it, deformation occurs, thereby improving the buffer effect and preventing deformation.
