Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1, a high voltage resistant structure for an insulating base of a microminiature electrical connector comprises a supporting spring coil 1, an upper base 2 and a lower base 4; the lower base 4 is connected with the upper base 2 through an adhesive 3, and the adhesive 3 forms an adhesive surface 31 between the lower base 4 and the upper base 2; a plurality of upper base mounting holes 21 and lower base mounting holes 41 which correspond to each other in position are respectively arranged in the upper base 2 and the lower base 4, the upper base mounting holes 21 and the lower base mounting holes 41 form circular step holes, and spring supporting coils 1 are arranged in the upper base mounting holes 21; the spring supporting ring 1 is provided with a spring supporting ring gap 11, the spring supporting ring gap 11 is parallel to the axis direction of the spring supporting ring 1, and at least 2 symmetrically distributed trapezoidal protrusions 12 are axially arranged on the end face, close to the bonding face 31, of the spring supporting ring 1, as shown in fig. 2-4.
Further, the stay spring ring 1 is axially fixed in a circular stepped hole formed by the upper base 2 and the lower base 4, and the upper base 2 and the lower base 4 are bonded together by the adhesive 3.
The spring supporting coil 1 is cylindrical, and the upper base mounting hole 21 is circular.
The positions of the spring supporting coil notch 11 and the trapezoidal protrusion 12 are relatively fixed.
The side wall and the axial direction of the upper base mounting hole 21 are provided with positioning convex keys 22, the positioning convex keys 22 are matched with the spring supporting ring gap 11, and the orientation of the spring supporting ring gap 11 is determined by the positioning convex keys 22. The positioning tab 22 has a width t2 as shown in FIGS. 5-6. The width of the spring coil notch 11 in a free state is t1, so as to form radial elastic performance, as shown in fig. 3.
As shown in fig. 6, the positioning convex keys 22 are arranged at the same positions in the upper base mounting hole 21, i.e. face the same direction. After the supporting spring rings 1 are installed in the upper base installation hole 21, the supporting spring ring gaps 11 all face the same direction, and the facing direction ensures that the creepage distance between any 2 trapezoidal bulges of any adjacent 2 supporting spring rings 1 is the largest.
The inner diameter d1 of the upper base mounting hole 21 is smaller than the outer diameter d2 of the supporting spring coil 1 in a free state, so that the supporting spring coil 1 is ensured not to fall off, and the inner diameter d3 of the lower base mounting hole 41 is smaller than the outer diameter d 2' of the supporting spring coil 1 in a fixed state after being installed in the upper base mounting hole 21, so that sufficient axial supporting force is provided.
After the spring supporting ring 1 is installed in the upper base installation hole 21, the width t 1' of the spring supporting ring notch 11 (namely, after the spring supporting ring 1 is installed in the upper base installation hole 21, the width of the spring supporting ring notch 11) is smaller than the width t2 of the positioning convex key 22, so that the radial rotation of the spring supporting ring 1 is prevented, and the creepage distance between any 2 adjacent spring supporting rings 1 is ensured to be unchanged.
The height of the positioning convex key 22 is smaller than the wall thickness of the spring supporting coil 1.
