Description

A detachable sealed connector

technical field

The invention relates to the field of connectors, in particular to a detachable sealed connector.

Background technique

Due to the many uncertain factors in the underwater experiment environment, it is required that the underwater experiment device can not only adapt to the harsh underwater experiment environment, but also transmit the signal to the ground terminal as accurately and in time as possible. Therefore, as a connection device for connecting underwater equipment and terminals, connectors are widely used in various projects and experiments.

With the development of underwater engineering, the assembly relationship between equipment becomes more and more complex. Connectors can simplify the assembly problem between components, facilitate the integration and replacement of old and new components, and have flexibility. At the same time, the connector greatly reduces the maintenance difficulty of electronic components. When a component of the underwater device fails, the failed component can be quickly replaced when the connector is installed.

Most of the old connectors have a sintered structure, and the sintered-sealed connector has a relatively simple structure, that is, the outer shell is integrated with the internal pins and transmission cores through sintering to meet the sealing requirements. However, this method not only has cumbersome processing technology and high defective rate in actual production, but also often causes partial fracture of the connector due to environmental factors or improper human operation, and the connector is easily damaged, which makes the cost of the experiment high.

Contents of the invention

The invention aims at the shortcomings of existing connectors, and proposes a connector structure that can be disassembled and replaced, and can meet the basic requirements of signal transmission, which can effectively save experiment costs.

In order to achieve the above object, the present invention adopts the following technical solutions:

A detachable sealed connector is characterized in that it includes a shielding shell, a core wire, a centering insulating sealing component and a plug-in connection component.

The centering insulation and sealing assembly includes insulating rings and O-rings, the core wire and the shielding shell are coaxially installed, and multiple sets of insulating rings and O-rings are set between the core wires and the shielding shell to perform insulation, centering and sealing functions.

The plug-in connection kit consists of cables, BNC connectors, adapters and rubber boots. One end of the BNC connector is connected to the external cable, and the other end is threadedly connected to the adapter; the adapter is connected to one end of the shielding shell, and the rubber sleeve is interference fit with the other end of the shielding shell.

Further, the insulating ring is a multi-section insulating ring, the material of the insulating ring is non-conductor, and the shape of a cylinder.

Further, the shielding shell is a cylindrical conductor, and the shielding shell has a circle of ring-shaped protrusions, which can realize the positioning of the rubber sleeve.

Further, the core wire is an elongated conductor, and there is a prism at one end of the connecting adapter to realize the positioning of the adapter.

Further, there is a groove on the core wire, and the size of the groove meets the standard for matching with the O-ring.

Further, the outer diameter of the core prism is smaller than the inner diameter of the shielding layer.

Another improvement of the present invention is that the outer surface of the shielding shell can be machined with grooves, supplemented with O-rings for signal transmission of the tank, and the O-rings can realize positioning and insulation with the tank body.

Another improvement of the present invention is that the outer surface of the shielding shell can be painted with insulating varnish or covered with insulating materials, so as to prevent the insulating layer from communicating with other objects and conducting electricity.

It should be seen that the described improvements are only part of the improvements of the present invention, not all of them. Based on the improvement scheme in the present invention, all other improvements obtained by persons of ordinary skill in the art without creative work fall within the protection scope of the present invention.

The beneficial effects of the present invention are: the basic requirements of signal transmission are realized by using the structure of the present invention, the detachability of the entire connector is realized by using a simple structure combination, and the cost of the connector is greatly reduced compared with the old sintered structure .

detailed description

The present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation examples.

Referring to Fig. 1 , the detachable sealed connector in this embodiment includes a shielding shell 3, a core wire 4, a centering insulating sealing assembly and a plug-in connection assembly.

The centering insulating sealing assembly includes an insulating ring 5 and an O-ring 6 . The shielding shell 3 and the core wire 4 are coaxially installed, and multiple sets of insulating rings 5 and O-rings 6 are set between the core wire and the shielding shell to perform insulation, centering and sealing functions. The O-ring 6 and the core wire 4 are matched according to the O-ring assembly standard. The O-ring 6 can ensure that the insulating ring 5 and the core wire 4 are relatively stationary, and together with the edge platform of the core wire 4 constrain the connection between the core wire 4 and the shielding shell 3 Relative movement in the axial direction, the insulating ring 5 and the O-ring 6 constrain the relative movement in the radial direction of the core wire 4 and the shielding shell 3 so that they become a whole. Referring to accompanying drawing 2, the inner hole of the insulating ring 5 and the core wire 4 are transitionally fitted. When the length is the same, the multi-section insulating ring 5 requires lower machining accuracy and assembly requirements than a single one. The outer surface of the insulating ring 5 is in transition fit with the shielding shell 3 . When sealing connection with other external devices is required, an outer O-ring 7 can be configured in the embodiment of the present invention, and the outer O-ring 7 and the shielding shell 3 cooperate according to the O-ring assembly standard.

The plug-in connection assembly includes a BNC connector 1 , an adapter 2 and a rubber sleeve 8 . The BNC connector 1 is screwed to the adapter 2, the adapter 2 is connected to one end of the shielding shell 3, and the edge end of the core wire 4 is inserted into the adapter 2, and the rubber sleeve 8 is interference fit with the other end of the shielding shell. The adapter 2 and the O-ring 6 work together to keep the core wire 4 and the shielding shell 3 relatively stationary.

Referring to Figure 3, the inner hole at the left end of the shielding shell 3 is threaded according to the size of the adapter 2, and the adapter 2 and the shielding shell 3 are threaded, and the axial length of the helix on the adapter 2 determines the relative position of the adapter 2 and the shielding shell 3 relation.

Referring to accompanying drawing 4, the right end of shielding shell 3 and rubber sleeve 8 are interference fit, and the protrusion outside shielding shell and the corresponding groove in rubber sleeve 8 constrain the relative position of shielding shell 3 and rubber sleeve 8 together.

The rubber sleeve and its supporting parts are inserted into the shielding shell 3, realizing the characteristics of quick plug-in and pull-out.

The assembly process of this embodiment is as follows:

First connect the cable 12 with the BNC connector 1; screw the BNC connector 1 and the adapter 2 into the end of the shielding shell 3 without protrusion as a whole; then put the insulating ring 5 and the O-ring 6 on the core wire in turn 4 as the whole two, wherein the O-ring 6 and the core wire 4 are matched according to the assembly standard; then the whole two is nested into the whole one as the whole three; the insulating layer 9 in the rubber sleeve is placed on the whole three; the rubber sleeve inner The shielding layer 10 is nested into the rubber sleeve 8, and the cable 11 is penetrated as a whole 4; the transmission signal layer and the shielding layer of the cable are respectively welded to the inner shielding layer 10 of the core wire 4 and the rubber sleeve of the whole 4, as a whole 5; Nest the whole four into the whole three; finally put the outer O-ring 7 on the shielding shell 3 . The disassembly process is just the opposite of the above process.
