Detailed Description
The technical solution of the present invention will be described in detail with reference to the accompanying drawings, but the scope of the present invention is not limited to the embodiments.
Example 1:
as shown in fig. 1 and 2, the utility model discloses a waterproof double-end elastic connector side by side includes: the needle comprises a disc-shaped needle body 1, two cylindrical contact pins 4 and two rebound compression springs 6; the upper side and the lower side of the disc-shaped needle body 1 are both vertically provided with a pin inserting blind hole 3, and the positions of the two pin inserting blind holes 3 are staggered; the hole wall of the pin blind hole 3 is provided with a guide chute 8; the two cylindrical contact pins 4 are respectively inserted into the two contact pin blind holes 3, and the outer wall of each cylindrical contact pin 4 is provided with a guide sliding block 9 which is embedded into a guide sliding groove 8 in a sliding manner; the two resilience compression springs 6 are respectively arranged in the two pin blind holes 3, and two ends of the resilience compression springs 6 are elastically supported between the inner end part of the cylindrical pin 4 and the bottom of the pin blind hole 3; a circle of ring grooves 14 are arranged around the circumferential side surface of the disc-shaped needle body 1; the circumferential edge of the upper side surface of the disc-shaped needle body 1 is provided with a communication notch 7 communicated with the ring groove 14. The communicating notch 7 can be used for conveniently pouring sealant into the annular groove 14 and the opposite limiting groove 16 after installation, so that the installation sealing property between the circumferential edge of the disc-shaped needle body 1 and the shell 15 is realized; the upper side surface and the lower side surface of the disc-shaped needle body 1 can be kept from being communicated by utilizing the two inserting needle blind holes 3 which are staggered mutually, the sealing performance is ensured, and the two cylindrical inserting needles 4 can have larger telescopic space after being inserted; utilize the cooperation of direction spout 8 and direction slider 9 can be spacing to cylindrical contact pin 4's flexible, and can prevent that cylindrical contact pin 4 from breaking away from contact pin blind hole 3.
Furthermore, four bosses 11 are arranged in the annular groove 14 at equal radian intervals, and limiting holes 12 are arranged on the bosses 11; a limiting pressure spring 13 is arranged in the limiting hole 12; a limiting convex column 2 is also inserted into the limiting hole 12; the limiting convex column 2 is pressed on the limiting pressure spring 13. The disc-shaped needle body 1 can be placed to be separated after installation by utilizing the arrangement of the limiting convex column 2, so that the structural strength after installation is enhanced; the limiting convex column 2 can rapidly extend into the limiting groove 16 at the mounting hole by utilizing the action of the limiting pressure spring 13 when the disc-shaped needle body 1 is inserted and mounted.
Further, the diameter of the limiting convex column 2 is smaller than the groove width of the annular groove 14. The diameter of the limiting convex column 2 is set to be smaller than the width of the annular groove 14, so that the upper side groove edge and the lower side groove edge of the annular groove 14 can be filled with sealant when the sealant is poured, and the reliability of waterproof sealing is ensured.
Further, a pressure spring mounting hole 5 is formed in the inner end portion of the cylindrical contact pin 4, and an end portion of the rebound pressure spring 6 is embedded in the pressure spring mounting hole 5.
