Detailed Description

The following detailed description is made of specific embodiments of the present invention with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and grasp, and thus make a clearer definition of the protection scope of the present invention.

The utility model discloses the designer is poor to the plug pin assembly intensity in the connector socket is used to current energy storage, and the objective of easily stolen tearing open is not enough, and pertinence ground configuration optimization, the innovation has provided a socket of single core connector, can effectively solve the plug pin theftproof and tear open, keeps the problem of the reliable butt joint of connector.

As shown in fig. 1 to 4, a conventional connector socket is provided with a single-core pin 3 and a socket housing 2 for inserting and positioning the pin 3 therein, the socket housing 2 has a base plate with a middle portion for fitting and abutting and front and rear sides thereof integrally extending, a front mouth 21 and a rear column 22 axially penetrating, and an abutting port of the front mouth 21 is provided with a chamfered stopper rib (not shown). The spacing rib part is mainly used for the butt joint and self-locking arrangement of the plug 6, and has been explained in other patent applications, so the detailed description is omitted here.

The utility model discloses a socket structure improves and sees from technical summary, socket housing 2's inner chamber has jump ring portion 24 and hidden buckle 23 of segmentation opening form along socket axial shaping, and 3 middle sections of contact pin correspond jump ring portion and are equipped with conical columnar jacking portion 33 and first draw-in groove 31, it is equipped with second draw-in groove 32 to correspond hidden buckle, and 3 next-door neighbour's second draw-in grooves of contact pin are equipped with appearance matching and hold in the stylobate 34 of postel 22 fit, under 3 and the socket housing 2 combination state of contact pin, hidden buckle 23 is fixed with second draw-in groove joint in the enclosure space A between jump ring portion 24 and stylobate 34. As shown in fig. 4, in the core of the design of the present invention, the contact pin 3 is inserted into the socket housing 2 from top to bottom, and then passes through the hidden clip by the top portion and the first slot, and is guided by the slope of the hidden clip, so that the hidden clip is not directly positioned and clasped in the first slot in the contact pin assembling and inserting direction; then deepen along with the degree of depth of inserting, make its joint in first draw-in groove behind the back shore portion with jump ring portion flaring, meanwhile hidden buckle can elastic release and hug closely the second draw-in groove in second draw-in groove department. The contact pin connects to target in place, and from the opposite direction of inserting, except that jump ring portion embraces and connects in first draw-in groove, hidden buckle also embraces and connects in the second draw-in groove, and unable rethread applys external force and makes hidden buckle open outward, and the contact pin can firmly be joined together with the socket shell under dual spacing promptly, the reinforcing effect that unusual interference fit can realize.

In the preferred embodiment shown, the hidden fasteners are only arranged in a pair uniformly distributed along the circumferential direction of the inner cavity, and in practice, the number of the hidden fasteners includes, but is not limited to, two hidden fasteners, and the hidden fasteners are uniformly distributed at equal intervals in the circumferential direction.

In a further refinement, the interior cavity of the tail cylinder 22 is formed with parallel opposed straight side walls 25, and the pylons 34 are formed as a trimmed cylinder. When the contact pin is assembled, the directional assembly with the socket shell is realized through the alignment flat pasting of the edge cutting and the straight edge wall. The joint closing means that the inner wall of the tail column is almost completely attached to the outer surface of the column base, the size of the joint is negligible, and the joint closing can be realized only by relative sliding of the inner wall of the tail column and the outer surface of the column base. Obviously, this eliminates the possibility of external tools reaching into the enclosed space, prying the hidden catch.

In addition, the base plate is provided with mounting holes distributed at four corners and a pair of through holes 26 with central symmetry therebetween, and the surface of one side of the base plate close to the tail column is provided with a sinking groove 27 avoiding the mounting holes. The socket is also sleeved with a cross-shaped rubber gasket 4 based on the tail post 22 and is contained in the sunken groove 27, and the cross-shaped rubber gasket 4 is integrally formed with a pair of mushroom heads 41 which are expanded and penetrated in the through holes to realize positioning. The rubber pad avoids the design of the mounting hole, so that the socket is more firmly mounted, and the connected bolt and nut are prevented from loosening and even separating due to the elasticity of the rubber pad. As the guarantee of waterproof performance after the socket assembly, this cross rubber pad has waterproof protruding glue at the surface shaping of being close to the tail post to the electric property terminal and the external environment of cavity are kept apart in the cooperation.

In summary, the present invention provides a connector receptacle with a solution introduction and an embodiment detailed description, which has substantial features and progressiveness: through the joint of two draw-in grooves of hidden buckle and jump ring portion cooperation, improved the location intensity of contact pin in the socket assembly, and accomplished the equipment back and sealed the dropout space of hidden buckle, guaranteed the contact pin theftproof when saving space and torn open conscientiously. Meanwhile, the assembly structure of the socket facing to the application object is optimized, so that the socket is more firmly installed.

In addition to the above embodiments, the present invention may have other embodiments, and all technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of the present invention.
