Embodiment

Below with reference to each embodiment shown in the drawings, the present invention will be described in detail.But these embodiments are not The limitation present invention, the conversion in structure or function that one of ordinary skill in the art is made according to these embodiments are wrapped Containing within the scope of the present invention.

According to Fig. 1 to Fig. 3, the invention provides a kind of retainer ring 100, is fixed and docked with clasp on coaxial connector Connector.The overall tapered extension of retainer ring 100.

The retainer ring 100 includes base portion 1 annular in shape and several outwards turn down the buckle 2 formed from base portion 1.Institute The width for stating the base portion 1 of retainer ring 100 is consistent, and formed with inserted terminal 10 and the clasp end 20 for being located at both ends respectively, institute The internal diameter for stating clasp end 20 is less than the internal diameter of inserted terminal 10, thus docking terminal can insert from inserted terminal 10 and be fastened in button easily Hold end 20.Some buckles 2 are from the 20 stamped formation of clasp end, and in the present embodiment, the buckle 2 is provided with three, certainly, The number of the buckle 2 is two or more, it can reach the purpose of the present invention.The buckle 2 is uniformly distributed in described In retainer ring 100, i.e. the distance of buckle 2 between any two is equal, and thus it is more equal to be held in stress when on buckle 2 for butt end subcard It is even.

As shown in Figure 2, the buckle 2 extends into arc shape and with holding part 22 and connection holding part 22 along clasp end 20 It is parallel with the inserted terminal 10 with the convergence part 21 at clasp end 20, the holding part 22.In the present embodiment, the clasp Portion 22 is located on the extended surface at clasp end 20, and the holding part 22 is generally aligned in the same plane with clasp end 20 so that coaxial connector When being docked with butt connector, butt connector can be fitted close with the retainer ring 100, be not in gap.

The outward bending of convergence part 21 shaping, and the angle that the convergence part 21 is bent is obtuse angle.The convergence part The thickness of holding part 22 described in 21 thickness ratio is big, it is ensured that during docking, the convergence part 21 can bear sufficiently large Pressure.The thickness of the holding part 22 becomes narrow gradually from convergence part 21 to free end.

The both sides of convergence part 21 of the buckle 2 are respectively equipped with otch 12, and the otch 12 is inside from the edge at clasp end 20 Depression.The otch 12 to be unlikely in buckle 2 described in punching press damage retainer ring 100.

The retainer ring 100 forms jagged 11, and the breach 11 axially penetrates through the retainer ring 100.The breach 11 When making and using the retainer ring 100, elastic space is provided to the deformation of retainer ring 100, so as to facilitate grafting.Institute The middle that breach 11 is formed at two wherein described buckles 2 is stated, and the breach 11 has from clasp end 20 to inserted terminal 10 vertical section, the vertical section of relative two of the breach 11 are parallel to each other.
