Abstract
The utility model discloses a sealing structure of a connector. The sealing structure comprises a housing equipped with a contact member and a protective cover. The housing is tightly fixed on the protective cover by internal-thread-and-external-thread screws, locking screws, and a sealing ring. The sealing structure has characteristics that the sealing ring is a profiled rubber pad equipped with a taper step and a taper end face. A U-shaped annular groove is disposed on the connecting end face of the protective cover. The protective cover is fixed on the housing by the cooperation of the internal-thread-and-external-thread screws and the locking screws. The sealing ring forms triple sealing structures between the housing and the protective cover including the taper step and the U-shaped annular groove, the taper step and the fence of the housing, and the taper end face and the end face of the housing. Compared with a product in the prior art, the sealing structure has triple reliable sealing interfaces and effectively guarantees the sealing performance of the connector. The sealing structure has simple structure and high reliability and is beneficial to a requirement of industrial quantity production.
Description
Technical field
The utility model relates to the electric components technical field, especially a kind of hermetically-sealed construction of connector.
Background technology
In today of telecommunications develop rapidly, the demand of communication apparatus is increasing, connector as the communication apparatus indispensability, also brought into play huge contribution at communication field, connector is the bridge of communication apparatus, play the effect of connection and hinge, after the applied environment of communication apparatus progressively becomes strictly, performance as the connector of Primary Component also will be due for promotion mutually, hermetically-sealed construction is the key point of connector design, is also the key point that can communication appliance performance reach estimated performance.At present, connector generally all adopts " O " shape hermetically-sealed construction, realizes the interfacial seal of over cap and shell component; the sealing structure can only realize the sealing of an end face; once this end face seal was lost efficacy, and will cause the whole seal failure of connector, affected the normal operation of communication apparatus.
Connector sealing property and the poor reliability of prior art, easily losing efficacy in seal interface, has a strong impact on the normal operation of communication apparatus.In order addressing this problem, and then to develop a kind of connector of multi-sealing structure, to have improved greatly the sealing property of connector, to meet the demand of actual use.
The utility model content
The purpose of this utility model is the hermetically-sealed construction of a kind of connector of designing for the deficiencies in the prior art, adopt the wedge-type seal structure, realize triple positiver sealings of connector, sealing property and the reliability of connector have been improved greatly, hermetically-sealed construction is simple, easy to process, be convenient to industrial batch production demand.
The purpose of this utility model is achieved in that a kind of hermetically-sealed construction of connector, comprise the shell and the over cap that are provided with contact, shell is fastened as a whole by negative and positive screw, lock-screw and sealing ring and over cap, the negative and positive screw is that an end is provided with external screw thread, the other end is provided with internal thread, the negative and positive screw suit is in the installing hole of shell both sides, and lock-screw and screw-internal thread fit, be characterized in that described sealing ring is the special-shaped rubber blanket that is provided with type conical bench and tapered end face; The connecting end surface of described over cap is provided with " U " shape annular groove; Described sealing ring is fastened in " U " shape annular groove; Described over cap is fixed on shell by negative and positive screw and lock-screw, and its sealing ring forms type conical bench and " U " shape annular groove, type conical bench and the fence of shell and the triple seal structure of tapered end face and shell end face between shell and over cap.
The utility model compared with prior art has triple positiver sealings interface, effectively guarantees the sealing property of connector, and simple in structure, reliability is high, is convenient to industrial batch production demand.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation
Fig. 2 is the shell mechanism schematic diagram
Fig. 3 is the shell stereogram
Fig. 4 is the over cap stereogram.
Embodiment
The utility model is to use like this: the external screw thread 51 by shell 1 by negative and positive screw 5 is fixedly connected on equipment, and " O " shape sealing ring 11 compressions on its connecting end surface realize the positiver sealing of shell 1 and equipment.Lock-screw 6 coordinates with the internal thread 52 of negative and positive screw 5, make the tapered end face 42 and shell 1 compression of sealing ring 4, realize type conical bench 41 and " U " shape annular groove 21, type conical bench 41 and the fence 12 of shell 1 and triple effective sealings of tapered end face 42 and shell 1 end face, greatly improved the sealability of connector.
More than just the utility model is further described, not in order to limit this patent, all is that the utility model equivalence is implemented, within all should being contained in the claim scope of this patent.
