Abstract
A sealed communicator comprises contact elements, an insulator, a cover board, an O-shaped ring, a housing and a closing ring. The insulator and the cover board are fixed in the housing with the closing ring; the O-shaped ring is arranged between the insulator and the housing; a closed hole having a chamfer is provided in the insulator. The sealed communicator is characterized in that each of the contact elements is provided with a rubber ring having a semicircular section, and is arranged in the closed hole in the insulator. One or a plurality of rubber rings having semicircular sections are provided on each of the contact elements; and the rubber rings seal the closed hole in the insulator by means of radial compression. The contact element is a one-piece structure of contact pins, plug jacks or pinholes. The seal structure of the contact element can be used for sealing plugs as well as sealing receptacles. The utility model has the advantages of that the utility model is applicable for the occasions which adopt small space minitype contact elements, and require self sealing capabilities and pressure seal capacities, excellent electrical properties of small conduction resistance, high insulation resistance and voltage resistance.
Description
Technical field
The utility model relates to a kind of hermetically sealed connector with contact sealing function, especially adopts little spacing, miniature contact and requires hermetically sealed connector with high pressure sealing ability and good electrical properties simultaneously.
Background technology
The existing various types of contact hermetically-sealed constructions that are used for electronic equipment adopt glass (pottery) sealing-in, rubber embedding, rubber seal, four kinds of forms of seal with O ring usually.When adopting glass (pottery) sealing-in form, contact must use the big alloy material of special resistance, easily causes the conducting resistance of contact to increase and insulation resistance decline.When adopting rubber embedding form, it is very big that sealing effectiveness is influenced by dosing technology, and reliability is not high.When adopting the rubber seal form, do not have the self sealss performance, sealing air pressure is lower.When adopting the seal with O ring form, be Φ 1.8mm, adopt seal with O ring less than the contact inconvenience of this size according to the standard O shape circle minimum diameter specification of standard GB/T3452 and the standard QJ1035 of Ministry of Aerospace Industry defined.
Summary of the invention
For the deficiency that the contact hermetically-sealed construction that overcomes above type exists, the utility model provides a kind of hermetically sealed connector with contact sealing function.Wherein all be equipped with the semi-circular cross-section rubber ring on each contact, be applicable to the hermetically sealed connector of little spacing, miniature contact, have high pressure sealing ability and good electrical properties (conducting resistance, insulation resistance, proof voltage).
The technical solution adopted in the utility model is: a kind of hermetically sealed connector, and it includes contact, insulator, cover plate, O shape circle, housing, collar; Described contact is contact pin, jack or pin hole integral structure, described insulator and cover plate are fixed in the housing with collar, be provided with O shape circle simultaneously between insulator and the housing, it is characterized in that: the closed hole that the band chamfering is arranged in insulator, all assemble on each contact and be socketed with the semi-circular cross-section rubber ring, and be set in the closed hole in the insulator.
All assemble on each contact and be socketed with one or more semi-circular cross-section rubber rings, this semi-circular cross-section rubber ring by with insulator in closed hole form radial compression and realize sealing.
Above-mentioned contact can be used for the sealing of plug with the hermetically-sealed construction of semi-circular cross-section rubber ring, also can be used for the sealing of socket.
Why the hermetically-sealed construction of this contact adopts the closed hole of semi-circular cross-section rubber ring and band chamfering, mainly be in order to solve two problems, the one, solve the technological forming problem of this rubber ring, the cross section of rubber ring is designed to semicircle by common circle (O shape), increased the volume and the intensity of rubber ring, made the easy moulding of rubber ring.The 2nd, solve the assembly problem of little spacing, miniature contact rubber ring, angle of friction when making the assembling of semi-circular cross-section rubber ring is less than stuck critical angle, the smooth assembling and the technology that have guaranteed miniature contact hermetically-sealed construction realize, the sealing structure is the radial compression form simultaneously, dwindle radial dimension, had the self sealss performance simultaneously.
The utility model has the advantages that: the sealing property that not only has known all kinds contact seal form (as glass (pottery) sealing-in, rubber embedding, rubber seal, seal with O ring etc.).Be particularly useful for the sealing of little spacing, miniature contact, and have self sealss ability and high pressure sealing ability, have good electrical properties (little conducting resistance, high insulation resistance and proof voltage).
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the sectional structure chart of hermetically sealed connector.
Fig. 2 is hermetically sealed connector assembling schematic diagram.
Fig. 3 is semi-circular cross-section rubber ring assembling schematic diagram.
Among the figure: 1. semi-circular cross-section rubber ring, 2. contact, 3. insulator, 4. cover plate, 5.O shape circle, 6. housing, 7. collar, 8. closed hole.
Embodiment
In Fig. 1, on each contact 2 all encapsulation connect and be furnished with semi-circular cross-section rubber ring 1, and be installed in the closed hole 8 of band chamfering on the insulator 3, contact 2 is provided with step, the diameter fit clearance of this step and insulator 3 closed holes 8 is very little, so that form an annular seal space, the closed hole 8 in the sealing chamber in semi-circular cross-section rubber ring 1 and the insulator 3 forms radial compression, realizes sealing by decrement and the compression ratio of determining rational rubber ring 1.Contact 2 is fixed between insulator 3 and the cover plate 4, and is fixed in the housing 6 with collar 7, is provided with O shape circle 5 simultaneously between insulator 3 and housing 6.
The assembling schematic diagram is seen Fig. 2, the O shape of in the groove of connector shell 6, packing into circle 5, on each contact 2, all assemble a semi-circular cross-section rubber ring 1, the contact 2 that sealing ring 1 will be housed then pushes by direction shown in Figure 2 that (it is suitable that the chamfer dimesion of closed hole and angle must design in the closed hole 8 of insulator 3 band chamferings, semi-circular cross-section rubber ring 1 is assembled in the closed hole of insulator 3 smoothly, as shown in Figure 3), cover cover plate 4, be assemblied in then in the connector shell 6, fixing with collar 7.
Fig. 3 is semi-circular cross-section rubber ring assembling schematic diagram.Chamfer dimesion and angle by appropriate design insulator 3 closed holes 8, angle of friction θ＜180 when making semi-circular cross-section rubber ring 1 assembling °, thereby semi-circular cross-section rubber ring 1 is assembled in the closed hole 8 of insulator 3 smoothly, has guaranteed that the technology of miniature contact hermetically-sealed construction realizes.
