Abstract
Description
Technical Field
[0001] The utility model relates to the field of electrical devices, and more specifically, to high-voltage power equipment and a high-voltage connector. Background Art
[0002] The current market demand for high-voltage connectors is becoming more and more compact, and the working voltage is also getting higher and higher. Different products have different fixing directions for cables and copper connecting plates. Usually, a terminal block or a terminal block is set at the end of the flat copper connecting plate for cable connection. The wiring direction is perpendicular to the copper connecting plate, which can meet the use requirements of a working voltage of 1000V DC.
[0003] If the placement direction of the copper connecting plate remains unchanged and the cable connection direction at the end changes, such as the terminal block or the terminal block at the end of the copper connecting plate is rotated 90 degrees relative to the fixed direction of the copper connecting plate, while maintaining the existing connector size and board end interface size, the distance between the two adjacent copper connecting plate ends side by side is too close, and the working voltage cannot meet the 1000V DC requirement.
[0004] In addition, in various previous high-voltage connector solutions, when the high-voltage connector product is assembled to the equipment end, there is no fixed position for the wiring harness at the tail end. The wiring harness is usually fixed in the air with a cable tie, and the wiring is relatively messy. Utility Model Content

[0025] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.
[0026] like Figure 1 As shown, a high-voltage electric power device in a preferred embodiment of the utility model includes a housing 1, a high-voltage connector 2 installed on the side wall of the housing 1, and electrical components arranged in the housing 1, and the high-voltage connector 2 can be connected and conducted with the electrical components in the housing 1.
[0027] Combination Figures 2 to 3 As shown, the high-voltage connector 2 includes a connection base 21, a first terminal 22, a second terminal 23, and an isolation structure 24. In this embodiment, the first terminal 22 and the second terminal 23 are plugged into the connection base 21, one end of which extends out of the shell 1 for external plugs to be connected, and the other end extends into the shell 1 for electrical components inside the shell 1 to be connected.
[0028] Furthermore, the first terminal 22 includes a first body 221 and a first connection portion 222, and the second terminal 23 includes a second body 231 and a second connection portion 232. The first body 221 and the second body 231 are plate-shaped, arranged in parallel, and arranged side by side on the connection seat 21. They can be plugged into the connection seat 21, or the first body 221 and the second body 231 can be covered and fixed when the connection seat 21 is formed. One end of the first body 221 away from the first connection portion 222 extends out of the housing 1, and one end of the second body 231 away from the second connection portion 232 extends out of the housing 1 for plugging and conducting with an external plug; the first connection portion 222 and the second connection portion 232 are located on the inner side of the housing 1 for connecting cables, connection plates 3 and other lines.
[0029] Preferably, the first connection part 222 and the second connection part 232 are arranged adjacent to each other, and the distance between the first connection part 222 and the second connection part 232 is smaller than the distance between the first body 221 and the second body 231, so that the direction of the first connection part 222 relative to the first body 221 can be adjusted, and the direction of the second connection part 232 relative to the second body 231 can be adjusted. At this time, since the distance between the first connection part 222 and the second connection part 232 is close, an arc will be generated. The isolation structure 24 isolates between the first terminal 22 and the second terminal 23, and isolates the first connection part 222 and the second connection part 232 from being directly opposite to each other, which can increase the creepage distance between the first connection part 222 and the second connection part 232, and will not generate an arc, which can meet the needs of high-voltage circuits, for example, it can meet the use needs of a working voltage of 1000V DC.
[0030] In some embodiments, the first connection portion 222 is plate-shaped and is bent toward the side adjacent to the first body 221 and the second body 231, and the second connection portion 232 is plate-shaped and is bent toward the side adjacent to the second body 231 and the first body 221. Preferably, the first terminal 22 and the second terminal 23 are symmetrically arranged, so that the first connection portion 222 and the second connection portion 232 are located between the first body 221 and the second body 231, and the wiring direction of the two terminals can be changed.
[0031] The first connection part 222 and the second connection part 232 are respectively provided with locking holes A for locking external conductors. The conductor can be a cable, and the head of the cable is locked and fixed through a connector. The conductor can also be a connecting plate 3, and a connecting hole is provided on the connecting plate 3 to be locked and fixed with the locking hole A.
[0032] In some embodiments, the isolation structure 24 includes an isolation plate, which isolates the first terminal 22 and the second terminal 23, isolates the first connection part 222 and the second connection part 232, and increases the creepage distance between the first connection part 222 and the second connection part 232 to improve the working voltage.
[0033] Usually, the isolation plate is detachably mounted on the connection base 21. When the connection base 21 is installed with different terminals, if isolation is not required, the isolation plate can be removed to reduce costs. It can be understood that in other embodiments, the isolation structure 24 and the connection base 21 are an integrated structure, so that the connection base 21 can simultaneously meet the needs of terminals with different structures.
[0034] Furthermore, the connection base 21 is provided with a low-voltage port 25 for plugging in the low-voltage line 4 on the side where the first connection part 222 and the second connection part 232 are located, which can meet different power connection requirements. The low-voltage port 25 is located between the first terminal 22 and the second terminal 23, and a fixing structure 241 for fixing the low-voltage line 4 is provided on the isolation structure 24, which is convenient for storing and organizing the low-voltage line 4 without affecting other wiring and components.
[0035] The fixing structure 241 includes a fixing position for binding and fixing the harness of the low-voltage line 4. The low-voltage line 4 is bound to the fixing position by using a cable tie, a rope, etc. to avoid performance problems caused by shaking of the harness. In other embodiments, the fixing position of the fixing structure 241 can also be used for clamping and fixing the harness of the low-voltage line 4, so that the low-voltage line 4 is clamped and fixed, and the fixing structure 241 can also be clamped and fixed and bound at the same time.
[0036] Specifically, the fixing position may include at least one of a lock buckle and a wire hole, that is, the lock buckle can be engaged with the low-voltage wire 4, and the wire hole can be passed through by a cable tie, and then the low-voltage wire 4 is bound and fixed.
[0037] It can be understood that the above-mentioned technical features can be used in any combination without limitation.
[0038] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
