Abstract
The invention relates to the field of electric connectors, in particular to a deepwater seal connector and a manufacturing method thereof. The front end of the deepwater sealing connector is taken as a plugging end, and the deepwater sealing connector comprises a shell, an insulator, a vulcanizing body and a contact element connected with a lead wire, wherein the insulator and the contact element are vulcanized together through the vulcanizing body which is assembled in the shell in an interference manner and is in seal fit with the inner wall face of the shell. According to the deepwater seal connector disclosed by the invention, the vulcanizing body is assembled in the shell in the interference manner and is in seal fit with the inner wall face of the shell, the insulator and the contact element are vulcanized together through the vulcanizing body, accordingly, the insulator and the contact element are vulcanized together outside the shell through the vulcanizing body, the probability of residual air bubbles between the contact element and the vulcanizing body as well as between the insulator and the vulcanizing body are reduced greatly without the disturbance of the shell, so that the air bubbles between the vulcanizing body and the contact element can be reduced, and the problem of seal unreliability of the traditional deepwater seal connector is solved.
Description
Technical field
The present invention relates to electric connector field, especially a kind of deep water sealing connector and manufacture method thereof that can be applicable in the deepwater environments such as seabed.
Background technology
At present, in electric connector field, have the electric connector that plugs function under water and all require product each contact after deepwater environment plugs together to realize isolation, avoid short circuit.And hard material is difficult to distortion, therefore can not satisfy system requirements, so product is to adopt the rubber curing forming structure mostly in the prior art.
The patent No. is that the Chinese patent of 200910304515.X discloses a kind of plug, this plug is exactly a kind of of deep water sealing connector, it comprises plug casing and pin insulator, axially be equipped with one group of jack contact on the pin insulator, front end and perisporium sulfuration at pin insulator are coated with plug sulfuration body, insulator is closely linked by plug sulfuration body and plug casing, the plug contact fixedly becomes integral body by plug sulfuration body, thereby realized the isolation of plug contact after plug and plug plug together; But, all be pin insulator and plug contact fixedly to be assemblied in just to vulcanize sealing in the plug casing first in practical operation, this is so that the gas of the junction of the linkage interface place of plug sulfuration body and pin insulator and plug sulfuration body and plug contact is difficult to discharge, thereby cause the sealing property of plug to be guaranteed, especially when bubble appears in the junction of plug sulfuration body and plug contact, bubble position will directly form the bottleneck of plug waterproof sealing performance.
Therefore, there is the insecure defective of sealing in present deep water sealing connector.
Summary of the invention
The object of the present invention is to provide a kind of deep water sealing connector, to reduce the bubble between sulfuration body and the contact, solve the insecure problem of sealing of existing deep water sealing connector.
Simultaneously, the present invention also aims to provide the manufacture method of above-mentioned deep water sealing connector.
In order to address the above problem, deep water sealing connector of the present invention is by the following technical solutions: the deep water sealing connector, this connector is take front end as inserted terminal, comprise housing, insulator, sulfuration body and the contact that is connected with wire, described insulator and contact sulfide by the sulfuration body, and sulfuration body interference is assemblied in the housing and is sealed and matched with the internal face of housing.
Described sulfuration body is sealed and matched by being located at bulge loop structure on its outer peripheral face and the internal face of housing.
The sulfuration body inserts housing from the front end of housing, and the internal face of housing is provided with draw-in groove, and the outer peripheral face of sulfuration body is provided with the hangnail structure corresponding with described draw-in groove.
The outer peripheral face of described insulator is provided with annular groove also by described annular groove and the clamping of sulfuration body.
The trailing flank embedding of insulator has location encapsulating body, the position the wire rear side of insulator of location encapsulating body.
Described location encapsulating body cooperates with body clearance, and the rear end embedding of housing has sealing encapsulating body, and sealing encapsulating body will locate the encapsulating body and wire is fixed in the housing.
Deep water sealing connector manufacturing method of the present invention is by the following technical solutions: make the method for above-mentioned deep water sealing connector, may further comprise the steps: 1) will insert with the contact of wire in the with it corresponding installing hole on the insulator with contact and insulator pre-determined bit; 2) generate the sulfuration body by vulcanization process, the sulfuration body is integrated contact and insulator sulfuration; 3) generate location encapsulating body by the trailing flank encapsulating at insulator, location encapsulating body pre-fixes wire and insulator; 4) will be with the sulfuration body of contact, wire, insulator and location encapsulating body being filled in the housing by force from front to back.
Comprise that also step 5) passes through to form sealing encapsulating body at the rear end of housing encapsulating, sealing encapsulating body is fixed on wire and location encapsulating body in the housing.
Described sulfuration body is sealed and matched by being located at bulge loop structure on its outer peripheral face and the internal face of housing, and the internal face of housing is provided with draw-in groove, and the outer peripheral face of sulfuration body is provided with the hangnail structure corresponding with described draw-in groove.
The outer peripheral face of described insulator is provided with annular groove also by described annular groove and the clamping of sulfuration body.
Because deep water sealing connector of the present invention is its sulfuration body interference is assemblied in the housing and is sealed and matched with the internal face of housing, insulator and contact sulfide by vulcanizing body; Hence one can see that, insulator and contact sulfide at the outside body that cures, owing to there has not been the interference of housing, reduced greatly between contact and the sulfuration body and the probability of residual bubble between insulator and the sulfuration body, thereby can reduce the bubble between sulfuration body and the contact, solve the insecure problem of sealing of existing deep water sealing connector.
Further, when the sulfuration body was sealed and matched by the internal face of being located at bulge loop structure and housing on its outer peripheral face, the bulge loop structure similarly was the sealing ring that is wholely set on the sulfuration body, had increased thus and had vulcanized the reliability that seals between body and the housing; Draw-in groove and hangnail structure have guaranteed the reliability of the secure fit between housing and the sulfuration body; Annular groove on the insulator outer peripheral face has avoided insulator be combined firm problem generation with the sulfuration body effectively; Location encapsulating body has been realized the pre-determined bit to wire, has made things convenient for the carrying out to the follow-up assembly work of connector; Sealing encapsulating body has been realized fixing to location encapsulating body and even insulator, sulfuration body, contact and wire on the one hand, has also guaranteed on the other hand being sealed and matched between the sealing of housing rear end and insulator and the housing.
