Embodiment
The present invention is introduced in detail below in conjunction with accompanying drawing and embodiment thereof.
Following institute drawings attached is only convenient to explain that the present invention instructs substantially, in accompanying drawing by form the number of assembly of preferred embodiment, position, relation and size extension will have illustrated by, in reading and understand the change that instruction of the present invention is correlated with afterwards and belong to industry technical ability.In addition, in reading and after understanding instruction of the present invention, specific strength, weight, intensity and the accurate dimension of similar requirement and the change of dimension scale is coordinated also to belong to general knowledge known in this field.
As shown in Figure 1, 2, 3, a kind of solenoid valve plug-in unit female end sheath, it comprises:
Sheath main casing 2 is looped wrap;
Plug-in unit positioning means 1, described plug-in unit positioning means 1 inside is provided with female terminal introduction chamber 13, female terminal guiding groove 11 and male terminal termination socket 12, and described female terminal guiding groove 11 is communicated with female terminal introduction chamber 13; The inside of described sheath main casing 2 is located in this plug-in unit positioning means 1 one end, and this end outer wall and described sheath main casing 2 inwall form the annular groove 4 inserted for plug-in unit male end termination sheath, it is inner that this end is located at by described female terminal guiding groove 11 and male terminal termination socket 12; Described plug-in unit positioning means 1 the other end stretches to the outside of described sheath main casing 2, and it is inner that described female terminal introduction chamber 13 is located at this end;
Locking mechanism 3, is located on the sidewall of described plug-in unit positioning means 1, and its one end is provided with the location hook 31 coordinated with the positioning hole in plug-in unit male end sheath, and its other end is provided with the press handle 32 of the outside stretching to described sheath main casing 2.
In order to prevent the anticreep of female terminal, the present invention devise cleverly once with secondary locking structure; Wherein a locking mechanism is: on the inwall of described female terminal introduction chamber 13, be provided with female end subcard ear 15 and draw-in groove 16.It assembled in draw-in groove 16 by being pressed in card ear when card ear 15 working state, the end hook mechanism of this scale ear 15 can prevent female terminal from retreating in female terminal introduction chamber 13.Preferred, in order to make the secure fit of Ka Er and draw-in groove, described draw-in groove 16 inwall is provided with anti-drop block 17.
Secondary locking structure is: in described female terminal guiding groove 11, be provided with retaining wedge 14.Described retaining wedge 14 is step-like, and produce certain amount of interference by the both wings fin of step realization and female terminal, after female terminal inserts, the fin on female terminal opens and is stuck on step, prevents female terminal from deviating from.
In order to increase frictional force, described press handle 32 is provided with step 33.Be three grades of small stairs in Fig. 3, press this handle 32 and the positioning hole on locking and positioning hook 31 and male plug part can be made to depart from, help to be separated male and female plug-in unit.
As shown in Figure 2, sheath main casing 2 inner homogeneous distributes six stiffening ribs 6, can play the effect of strengthening, and adjusts the interworking tightness degree with male end plug-in unit by the thickness adjusting stiffening rib, occurs rocking after preventing interworking.
Preferably, described plug-in unit positioning means 1 is column, and its post rib place is provided with chamfering 18.As shown in Figure 2, four angles of described plug-in unit positioning means 1 have different chamferings 18, can pass through the difference realization of chamfering and the assembling error-disable function of male plug part.
Further, the invention provides a kind of solenoid valve plug-in unit, it comprises above-mentioned solenoid valve plug-in unit female end sheath and solenoid valve plug-in unit male end 5.Described solenoid valve plug-in unit male end, as shown in Figure 4, its end is extended with male end termination 52, and this outside, termination is provided with male end termination sheath 51.After solenoid valve plug-in unit assembling of the present invention, as shown in Figure 5, described male end termination 52 is mated with the male terminal termination socket 12 of described solenoid valve plug-in unit female end sheath, and described male end termination sheath 51 mates with described annular groove 4.
The above is only the preferred embodiment of the present invention, it is to be noted, these embodiments are only not used in for illustration of the present invention and limit the scope of the invention, and, after having read content of the present invention, relevant technical staff in the field can make various change or amendment to the present invention, and these equivalent form of values fall into the application's appended claims limited range equally.
