Further, the sealing slot cross-section is in a rectangular trapezoid, the installation portion rectangular in cross-section.
Further, the internal face of the seal groove extrudes the medial surface of the installation portion, makes the installation portion
Compressive deformation occurs for the medial surface.
Further, the limiting section is located at the end of the installation portion, and the limiting section has confined planes, described spacing
Face is consistent with the top surface width on the water jacket edge of the seal groove of the connector body and is bonded closely.
Further, the medial surface of the limiting section and lateral surface all have the gradient, and the gradient of the lateral surface is more than institute
The gradient of medial surface is stated, the top surface of the limiting section is in raised arc.
Further, the limiting section is integrally formed with the installation portion.
In above-mentioned water-proof connector, after the sealing ring is attached to seal groove, the bottom surface of the installation portion and the sealing
The bottom contact of groove, the inwall side of the seal groove have the gradient, make the top surface of the installation portion that elastic deformation occur, play
Preferable waterproof effect, and the sealing ring should not depart from.The waterproof connector structure is simple, is firmly combined with, good reliability,
Meet the mechanical environment and electrical performance demands of internal unit.
Brief description of the drawings
Fig. 1 is the water-proof connector section decomposition texture schematic diagram of the utility model embodiment.
Fig. 2 is the mplifying structure schematic diagram of the sealing slot part of the water-proof connector of the utility model embodiment.
Embodiment
The utility model is described in detail below with reference to specific embodiments and the drawings.
Fig. 1 and Fig. 2 are referred to, a kind of water-proof connector is shown, it includes connector body 10 and sealing ring 20, the company
Connecing device main body 10 has seal groove 11, and the sealing ring 20 includes the installation portion 21 and limiting section 22 for being inserted in seal groove 11, institute
State seal groove 11 width of rebate be less than the seal groove 11 bottom width, the bottom width of the installation portion 21 with it is described close
The bottom width of sealing groove 11 is consistent, and the bottom surface of the installation portion 21 contacts with the bottom of the seal groove 11, the limiting section 22
Project radially outwardly in the installation portion 21 to be stuck in the groove edge of the seal groove 11.
Further, the inner side internal face 111 of the seal groove 11 has the gradient.
The bottom surface angle of the internal face 111 of the seal groove 11 and the seal groove 11 is acute angle.
Preferably, the bottom surface angle a of the internal face 111 of the seal groove 11 and the seal groove 11 is 87 degree to 88
Degree.
Further, the section of seal groove 11 is in a rectangular trapezoid, the rectangular in cross-section of installation portion 21.
Further, the internal face 111 of the seal groove 11 extrudes the medial surface 211 of the installation portion 21, makes institute
Compressive deformation occurs for the medial surface 211 for stating installation portion 21, makes the sealing ring 20 difficult for drop-off during use, and play
More preferable waterproof effect.
Further, the limiting section 22 is located at the end of the installation portion 21, and the limiting section 22 has confined planes
221, the confined planes 221 are consistent with the top surface width of the outer of the seal groove 11 of the connector body 10 and paste closely
Close.Because internal face 111 described in the 11 inner side of seal groove has the gradient, the confined planes 221 of the limiting section 22
More closely it is pressed in the groove edge of the seal groove 11.
Further, the medial surface of limiting section 22 and lateral surface all have the gradient, and the gradient of the lateral surface is more than institute
The gradient of medial surface is stated, the top surface of the limiting section 22 produces elastic deformation when coordinating with miscellaneous part, made in raised arc
Coordinate even closer.
Further, the limiting section 22 is integrally formed with the installation portion 21, makes the sealing ring more sturdy and durable.
