Description

Technical Field

[0001] The utility model relates to the technical field of fuses, in particular to a DC fuse insulation protection component. Background Art

[0002] A DC fuse is an electronic component used to protect DC circuits and devices from overcurrent damage. It plays a role similar to a fuse in a DC circuit. When an excessive current appears in the circuit, the DC fuse will automatically disconnect the circuit to prevent the current from exceeding the set range, thereby protecting the safe operation of the circuit and equipment.

[0003] The two connection terminals of the DC fuse are respectively connected to the cables and the circuits, and one end of the cable is usually directly inserted into the connection terminal and fixed in the connection terminal by the fastening screws on the connection terminal. During the cable installation process, if the wiring is not firm, the terminal hole is not inserted correctly, and the crimping force is insufficient, the cable may fall off easily when subjected to external tension, which may cause certain inconveniences in the installation of the DC fuse. At the same time, when the cable is connected to the connection terminal of the DC fuse, one end of the cable needs to be stripped to expose the internal conductor part to ensure that the conductor can form a good electrical contact with the connection terminal, thereby realizing smooth transmission of current. However, when one end of the cable is stripped, part of the conductor is easily exposed, which may cause the exposed conductor to pose a safety hazard after the DC fuse is energized.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 - Figure 4 As shown, the utility model provides a DC fuse insulation protection component, including a protective shell 1, an end cover 2 is movably installed on the rear side of the protective shell 1, two connecting terminals 3 are fixedly installed in the protective shell 1, a protective cover 4 is fixedly installed on the front side of the protective shell 1, two partitions 5 are fixedly installed in the protective cover 4, two push plates 6 are movably installed in the protective cover 4 between the two partitions 5, a wedge block 7 is movably installed in the protective cover 4 between the two push plates 6, and wiring holes 8 are opened at the front side of the protective shell 1 near the two partitions 5.

[0023] The protective shell 1 between the two partitions 5 is provided with two slide grooves 9, and the protective shell 1 between the two slide grooves 9 is also provided with a screw groove 10. Two slide grooves 9 are provided on the front side of the protective shell 1 to provide conditions for the vertical movement of the push plate 6, and the setting of the screw groove 10 can provide conditions for the adjustment of the horizontal movement of the wedge block 7. Two insertion holes 11 are provided in the partition 5, and the two insertion holes 11 are staggered. Guide slopes 12 are respectively provided on the opposite sides of the two push plates 6. Two insertion rods 14 are fixedly installed on the side of the push plate 6 away from the guide slope 12, and the two insertion rods 14 are staggered. A T-shaped slider 13 is fixedly installed on one side of the push plate 6, the guide slope 12 is inserted in the protective cover 4, and the two insertion rods 14 are respectively inserted and installed in the corresponding insertion holes 11, and the T-shaped slider 13 is far away One side of the push plate 6 is inserted and connected in the corresponding slide groove 9, and a compression spring 15 is also installed on the outside of the insertion rod 14. One end of the compression spring 15 abuts on the corresponding partition plate 5, and the other end of the compression spring 15 abuts on the push plate 6. Through the two insertion rods 14 on the push plate 6, the wedge block 7 can be cooperated with the wedge block 7 to guide the cables inserted in the protective cover 4 in an interlaced manner, thereby playing the anti-drag function of the cable and protecting the exposed part of the cable connection and one end of the connection terminal 3. A countersunk hole 16 is opened in the middle part of the wedge block 7, and an adjusting screw 17 is inserted and installed in the countersunk hole 16.
