Specific embodiment

It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer The technical solution of the utility model embodiment is clearly and completely described in the attached drawing of type embodiment.Obviously, described Embodiment is a part of the embodiment of the utility model, instead of all the embodiments.Based on described the utility model Embodiment, those of ordinary skill in the art's every other embodiment obtained under the premise of being not necessarily to creative work, all belongs to In the range of the utility model protection.

As shown in Fig. 1-4, signal connector, including socket 1, plug 2, pin terminal 3, plug are disposed in socket Inside it is disposed with the socket terminal 4 with pin terminal cooperation, and the lock sleeve 5 that socket and plug is locked, socket periphery Be fixedly installed assembly bench 6, assembly bench and socket are integrally formed, and cover the sealing ring 7 outside socket, assembly bench be it is rectangular, The sealing ring is square rubber；The fitting surface outer periphery of assembly bench forms the lug boss 8 of annular, and sealing ring is by annular protrusion Portion is kept off on the inside of the fitting surface of assembly bench, and the two sides of sealing ring has convex ribs 9.

In order to obtain better seal performance, after sealing ring is installed to the fitting surface of assembly bench, convex ribs are slightly higher than protrusion Portion.

Socket includes Socket casing 10, pin terminal seat 11, the first locking nut 12, the first grommet 13, the first liner Set 14, pin terminal seat is in Socket casing, and the first grommet is in one end of pin terminal seat；First locking nut with Socket casing connection, the first grommet, pin terminal seat is assembled in Socket casing, the first neck bush is covered in the first envelope line On body and it is pressed on the first locking nut, cone match is used between the first neck bush and the first grommet, is different from traditional It faces design directly, facilitates grommet in the assembly of neck bush, the deformation of grommet can be oriented to, avoid the envelope for facing design directly There is direction-free deformation in wire body.With multiple contact pin mounting holes for pin terminal assembly in pin terminal seat.

Plug includes plug casing 15, socket terminal seat 16, the second locking nut 17, the second grommet 18, the second liner Set 19, socket terminal seat is in plug casing, and the second grommet is in one end of socket terminal seat；Second locking screw Mother connect with plug casing, the second grommet, socket terminal seat is assembled in plug casing, the second neck bush is covered second On grommet and it is pressed on the second locking nut, cone match is used between the second neck bush and the second grommet；Socket terminal With multiple pilot holes for socket terminal assembly in seat, contact pin mounting hole and the assembly hole number at this are according to the core number used To be arranged.

First neck bush, the second neck bush are metalwork.Certainly in this design, the neck bush of metalwork and plastic part is real It can be replaced mutually on border, and the advantages of metal inner lining set, is no deformation, and shrinkage is bad during plastic piece shaping Control, and metal machining or die sinking, precision is accurate, can ensure that the expansion for being assemblied in grommet therein is uniform.

The end that socket terminal is inserted into for pin terminal is provided with retaining claw 20, can prevent terminal from falling back in this way.

First grommet is identical as the second grommet structure, and the periphery of grommet is convex stupefied with convex stupefied 21 to be circular layout Section be that radian is arc-shaped less than 180 °, reduce convex stupefied height, plasticity becomes strong, in plug wire assembling process, inserts The deformable amount of string holes increases, and reduces the difficulty of plug wire, facilitates installation.

There is plug wire hole, plug wire hole includes first inner chamber 22, second inner chamber 23, first lead hole 24, second in grommet Fairlead 25, first inner chamber is connected to first lead hole, and the second fairlead is connected to second inner chamber, first inner chamber and second inner chamber Between form medial septum 26, cable passes through medial septum when use, and the thickness of medial septum is suitable for avoiding the occurrence of cable and wearing not Saturating problem is formed the blocking of an isolation by medial septum, and will form a sealing across the cable of plug wire hole, Improve waterproof effect.First inner chamber, second inner chamber are arc-shaped cavity, facilitate demoulding when injection molding, on the other hand, reduce plug wire mistake Frictional force in journey between cable and grommet, facilitates plug wire.
