Fig. 2 is the enlarged diagram of encircled portion in Fig. 1.
Fig. 3 is the schematic diagram at another visual angle of the utility model retainer ring.
Embodiment
Below with reference to each execution mode shown in the drawings, the utility model is described in detail.But these execution modes do not limit the utility model, the structure that those of ordinary skill in the art makes according to these execution modes or conversion functionally are all included in protection range of the present utility model.
According to Fig. 1 to Fig. 3, the utility model provides a kind of retainer ring 100, in order to coaxial connector to fix butt connector with clasp.Described retainer ring 100 entirety extends in taper.
Described retainer ring 100 comprises base portion 1 in the form of a ring and several are from the outside buckle 2 turned down of base portion 1.The width of the base portion 1 of described retainer ring 100 is consistent, and be formed with the inserted terminal 10 and clasp end 20 that lay respectively at two ends, the internal diameter of described clasp end 20 is less than the internal diameter of inserted terminal 10, and thus docking terminal can insert from inserted terminal 10 easily and be fastened in clasp end 20.Some described buckles 2 are formed through punching press from clasp end 20, and in the present embodiment, described buckle 2 is provided with three, and certainly, the number of described buckle 2 is two or more, all can reach the purpose of this utility model.Described buckle 2 is uniformly distributed on described retainer ring 100, and namely buckle 2 distance is between any two equal, time butt end subcard is held on buckle 2 thus stressed evenly.
As shown in Figure 2, described buckle 2 extends into arc shape along clasp end 20 and has holding part 22 and the convergence part 21 being connected holding part 22 and clasp end 20, and described holding part 22 parallels with described inserted terminal 10.In the present embodiment, described holding part 22 is positioned on the extended surface of clasp end 20, and described holding part 22 is positioned at same plane with clasp end 20, makes coaxial connector when docking with butt connector, butt connector can closely cooperate with described retainer ring 100, there will not be gap.
Described convergence part 21 bent outward foldable type, and the angle that described convergence part 21 bends is obtuse angle.The thickness of holding part 22 described in the Thickness Ratio of described convergence part 21 wants large, and when can ensure docking, enough large pressure can be born in described convergence part 21.The thickness of described holding part 22 narrows gradually from convergence part 21 to free end.
The both sides, convergence part 21 of described buckle 2 are respectively equipped with otch 12, and described otch 12 caves inward from the edge of clasp end 20.Described otch 12 in order to be unlikely to during buckle 2 described in punching press damage retainer ring 100.
Described retainer ring 100 is formed with breach 11, and described breach 11 axially runs through described retainer ring 100.Described breach 11, in order to when making and using described retainer ring 100, provides elastic space to retainer ring 100 deformation, thus facilitates grafting.Described breach 11 is formed at the middle of two wherein said buckles 2, and described breach 11 has the vertical tangent plane from clasp end 20 to inserted terminal 10, and the two relative vertical tangent planes of described breach 11 are parallel to each other.
Thus, docking terminal inserts from described inserted terminal 10, through described retainer ring 100, and holds mutually with clasp end 20.Described buckle 2 is through punch forming in clasp end 20 also outwards turnover, and structure is simple and cost is lower.The holding part 22 of described buckle 2 parallels with described inserted terminal 10, and described holding part 22 intensity is large and toughness is high, docking terminal effectively can be supported, and have good firm locking effect.
Further, described retainer ring 100 is preferably made up of beryllium-bronze material.Beryllium-bronze is a kind of precipitation hardenable alloy, and have very high intensity, hardness, elastic limit and fatigue limit after fixation rates, elastic hysteresis is little, and has corrosion resistance characteristic, because of but a kind of fabulous material on coaxial connector.But because this beryllium-bronze material hardness is large, elastic hysteresis is little, so when inside and outside being formed after needing to ensure flange, R angle is less, overall flange forms buckle 2 and is easy to fracture.Therefore, several spaced buckles 2 are set in order to support docking, high strength and the high rigidity of beryllium-bronze material can be utilized, again can when ensureing to realize less bending R angle, forming buckle 2 by punching press flange can not generating material fracture.
Certainly, in other embodiments, described retainer ring 100 also can use other materials to make, as stainless steel etc., depending on actual demand.When using stainless steel to make retainer ring 100, when inside and outside being formed after ensureing flange, R angle is less, first general technology will be taken out retainer ring 100 and draw technique before overall flange forms buckle 2, and then carried out can not rupturing by generating material when punching press forms buckle 2 to ensure overall flange.And adopt the utility model to design, buckle 2 being designed to several and spaced setting, drawing technique without the need to taking out, directly can be realized by punching press.So can simplify processing procedure, cost-saving.
Be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, technical scheme in each execution mode also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
A series of detailed description listed is above only illustrating for feasibility execution mode of the present utility model; they are also not used to limit protection range of the present utility model, all do not depart from the utility model skill equivalent implementations of doing of spirit or change all should be included within protection range of the present utility model.
