Abstract

The utility model relates to a resin-potted flow guide sleeve for a sensor connector, and the flow guide sleeve comprises a guide tube. The inner wall of the guide tube is provided with a horizontal sealing unit which is coaxially provided with a plurality of pin holes, wherein the pin holes are used for the axial extension of connector pins. The central part of the horizontal seal unit is provided with a through hole which is coaxial with the guide tube and used for the downward flowing of liquid resin. According to the utility model, the resin in the connector is isolated from air through the horizontal sealing unit. When the inner space, under the horizontal sealing unit, of the connector is filled with resin, the potting of resin cannot be carried out continuously, thereby avoiding an insufficient filling of resin. Moreover, the pin holes in the horizontal sealing unit effectively protect the pin from contacting with the resin.

Description

For the resin perfusion flow guide sleeve of transducer connector

Technical field

The utility model belongs to sensor field, relates to resin Sealing Technology, the especially a kind of perfusion of the resin for transducer connector flow guide sleeve.

Background technology

Connector is also connector, domestic also referred to as joint and socket, generally refers to electrical connector, connects the device of two active devices, transmission current or signal.The transducer of current this product is all widely used in Aeronautics and Astronautics technology and industrial production.But in above-mentioned field, because component environment is comparatively severe, especially under the state such as hyperbar, high hydraulic pressure, being very easy to docking card sensor destroys, and on the other hand, the frequent appearance of Partial Jobs environment is acutely rocked, and not only easily causes coming off of connector, and causes the damage of the precise part such as circuit board or needle stand in connector.

The method that solves at present such scheme adopts filling resin material that connector inwall and circuit board space are around sealed conventionally, but along with scientific and technological development, connector transducer is more and more accurate, and volume is more and more less, it is increasing that this just causes pouring into difficulty, operation to connector internal resin and injection rate are difficult to hold, and easily cause contact pin on connector to be infected with resin or resin filling small volume, do not reach use standard.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of simple in structure, reasonable in design, use the stable resin for transducer connector perfusion flow guide sleeve.

The utility model solves its technical problem and takes following technical scheme to realize:

A kind of perfusion of the resin for transducer connector flow guide sleeve, comprise a conduit, on this pipe inner wall, be shaped with horizontal shutoff, in this horizontal shutoff, be coaxially shaped with multiple pin holes that axially stretch out for socket connector pin, be shaped with one coaxial and for the through hole of the downward inflow of liquid resin resin with conduit at horizontal shutoff middle part.

And described conduit is shaped with upper and lower opening.

And, on the position of described conduit under shed outer rim, be shaped with one with the homoaxial banking stop of conduit.

And, be provided with fin or be provided with depression at described banking stop inner edge in described banking stop outer rim.

Advantage of the present utility model and good effect are:

1, the utility model by horizontal shutoff by the resin in connector and air insulated; after in connector below horizontal shutoff, space is filled up by resin; resin cannot continue perfusion; avoid thus resin filling inadequate, and pin hole in horizontal shutoff effectively protect contact pin can not be infected with resin.

2, the utility model is just provided with banking stop in conduit lower end, is provided with fin or is provided with groove at banking stop inner edge in banking stop outer rim, is convenient to thus the axial location of connector at plug-in unit shell, is convenient to thus the operation of flow guide sleeve in plug-in unit cover top portion.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 be in Fig. 1 A-A to cross-sectional view.

Embodiment

Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.

For a resin perfusion flow guide sleeve for transducer connector, comprise a conduit 1, this conduit is shaped with upper and lower opening.

Innovative point of the present utility model is:

On this pipe inner wall, be shaped with horizontal shutoff 5, in this horizontal shutoff, be coaxially shaped with multiple pin holes 3 that axially stretch out for socket connector pin, be shaped with one coaxial and can be for the through hole 4 of the downward inflow of liquid resin resin with conduit at horizontal shutoff middle part.

On the position of conduit under shed outer rim, be shaped with one with the homoaxial banking stop 2 of conduit.

Using method of the present utility model is:

This resin perfusion flow guide sleeve is coaxially installed at the plug-in unit shell aperture place of transducer connector, in plug-in unit shell, be coaxially installed with circuit board, the coaxial socket connector pin that is provided with on circuit board, pinhole design need to be coaxially corresponding with socket connector pin position, pin hole length also needs corresponding with socket connector pin length coupling, pin hole needs hard-pressed bale socket connector pin and socket connector pin top can protrude upward pin hole, be provided with fin or be provided with depression at banking stop inner edge in banking stop outer rim, be convenient to thus the axial location of connector at plug-in unit shell.

Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: not departing from the spirit and scope of the utility model and claims, various replacements, variation and amendment are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
