Referring to fig. 1 and fig. 2, an embodiment of the present application provides a voltage withstanding structure 600, including a base 610, a partition 620, and a first connector 630, where the partition 620 is provided with a first hole 621, a portion of the first connector 630 passes through the first hole 621, is mounted on the base 610, and is fixed to the first connector 630 by glue, and the first connector 630 is configured to be electrically conductive when connected to other components. The first connecting piece 630 is fixed by glue and the first hole 621 is limited to the first connecting piece 630, so that the first connecting piece 630 can be stably installed on the seat body 610, and the first connecting piece 630 has good pressure resistance.
Referring to fig. 1 and 2, in particular, the holder body 610 is hollow, a first mounting port 611 and a second mounting port 612 are formed at two ends of the holder body 610, and the first mounting port 611 is communicated with the second mounting port 612; the partition 620 is disposed inside the holder body 610, and the partition 620 is integrally connected to the holder body 610, it should be understood that the partition 620 is a baffle plate, and is parallel to a plane where the first mounting hole 611 and the second mounting hole 612 are located when the holder body 610 is disposed inside, and the partition 620 divides the holder body 610 into a first cavity 613 and a second cavity 614; the first hole 621 is disposed on the partition 620, the first hole 621 communicates the first cavity 613 with the second cavity 614, the first connector 630 passes through the first hole 621, and a part of the plate body of the first connector 630 is located in the first cavity 613 and the second cavity 614; wherein at least one of the first cavity 613 and the second cavity 614 is filled with glue for sealing the first hole 621. By providing the first and second mounting openings 611 and 612, other components, such as a sleeve, and the like, can be connected to the housing 610, and the connectable components can be made of metal material, synthetic plastic, and the like, so as to protect the first connector 630; by dividing the base 610 into the first cavity 613 and the second cavity 614, the first connector 630 has a certain installation space when being installed and is convenient to glue so as to fix the first connector 630.
In some specific embodiments, the first connector 630 is a circuit board, and the first hole 621 is a strip-shaped hole, because the circuit board is in the shape of a plate body, when the circuit board is installed in the strip-shaped hole, the strip-shaped hole can better limit the circuit board to prevent the circuit board from shifting, and meanwhile, under the action of glue, the circuit board can be firmly installed on the partition 620, so that the circuit board has good pressure resistance, and can also keep stable position under the condition of high pressure.
In the present application, the space of the first cavity 613 is smaller than that of the second cavity 614, the glue filled in the first cavity 613 is used for fixing the first connector 630, and the second cavity 614 is also used for filling a part of glue to fix the first connector 630, because the space of the first cavity 613 is small, when the amount of glue filled in the first cavity 613 is equal to that of the glue filled in the second cavity 614, the glue in the first cavity 613 can be more combined with the first connector 630, the combining surface on the first connector 630 is larger, so that the fixing effect of the first connector 630 under the action of the glue is better, and because the first connector 630 is inserted into the first hole from the first cavity 613, the first connector 630 can be fixed only by filling the glue in the first cavity 613, because first connecting piece 630 with there is the gap when first hole 621 connects, through glue, can fill the gap to make be sealing connection between first connecting piece 630 and the first hole 621, the effectual sealing performance of having guaranteed the product, and because only need a bit glue just can make first connecting piece 630 can be firm install on the pedestal 610, the effectual cost that has reduced.
Referring to fig. 2, in the present embodiment, the first connector 630 includes a first plate 631, a second plate 632, and a third plate 633, and the first plate 631, the second plate 632, and the third plate 633 are integrally connected; the first plate 631, the second plate 632, and the third plate 633 are stepped;
when the first connector 630 is mounted to a predetermined mounting position through the first hole 621, the first plate 631 is located outside the first cavity 613, the second plate 632 is located in the first cavity 613, and the third plate 633 is partially or completely located in the second cavity 614; the first plate 631 is configured to be connected to an element outside the first cavity 613, and the third plate 633 is configured to be connected to other elements so that the element connected to the third plate 633 can be connected to a component connected through the first plate 631.
In this application, because the first connector 630 is a circuit board, therefore, the second plate body 632 mainly plays a role in communicating the first plate body 631 with the third plate body 633, in order to make the third plate body 633 better connected with other elements, for example, the third plate body 633 can not be received when being connected with other elements through modes such as inserting, welding, etc. the second mounting port 612 is limited, the plate body length of the third plate body 633 is set to be flush with the opening end face of the second mounting port 612 or partially extend out of the second cavity 614.
