Detailed Description

The present invention is further described in detail below with reference to examples so that those skilled in the art can practice the invention with reference to the description.

It will be understood that terms such as "having," "including," and "comprising," when used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

Example 1

As shown in fig. 1-4, a high-stability automobile connector comprises a plug 2 and a socket 1 which are matched, wherein the socket comprises a first mounting plate 11 and a cylindrical first shell 12, a first opening 13 is formed in the bottom of the first shell, and the first mounting plate is fixed at the bottom of the inner side of the first shell or the first opening;

the side wall of the first shell is provided with an interlayer, and a cavity between the interlayers is sealed with glue 14 and compressed gas 15; the first housing is divided into a left reservoir 121 and a right reservoir 122; the lower parts of the inner sides of the left liquid storage part and the right liquid storage part are respectively provided with at least one liquid outlet nozzle 16; the glue is AB glue, and the component A and the component B of the AB glue are respectively stored in the left liquid storage part and the right liquid storage part; after the liquid outlet nozzle is opened, the glue is pressed out of the inner cavity by compressed gas; the pressure of the compressed gas should not be too great to prevent the glue from splashing too quickly and spilling out of the connector or forming a large amount of bubbles. The quantity of the packaging glue in the inner cavity between the interlayers is preferably that the air at each position of the connector can be filled up but not overflow (for example, the glue is filled up to the tubular extension part), the compressed gas expands after being pressed out of the interlayers, the quantity of the compressed gas is controlled, so that the compressed gas does not flush out the inner cavity between the interlayers or only a small amount of compressed gas flushes out, even if a certain amount of bubbles are arranged inside the glue after solidification, the packaging and moisture-proof effects are not affected, if more compressed gas flushes into the inner cavity, the air can be slightly vibrated to float upwards and overflow or the problems can be solved by adopting methods of stirring, pumping and the like.

A seal head/plug which is arranged to protrude out of the inner side surface of the first shell is arranged at the liquid outlet nozzle, and a seal head 17 is adopted in the embodiment; if the end socket is adopted, a thinner and brittle material is adopted at the end socket, so that the end socket can be easily broken when the plug is inserted into the second shell; the plug can be made of rubber and the like, and the depth of the plug inserted into the liquid outlet is not too large, so that the plug can be rapidly separated from the liquid outlet when encountering the second shell when the plug is inserted; in addition, the height of the liquid outlet should not be too low, and a certain downward space should be left when the seal head/plug is opened. When the plug is completely inserted into the socket, enough clearance is reserved between the lower edge of the second shell and the first mounting plate, so that the glue can smoothly flow into the second shell; or, the second shell is provided with a hole corresponding to the liquid outlet, so that the glue can enter the second shell from the hole. The lower edge of the second shell can be processed into a sharp part, the end socket/plug can also be provided with a matched slot, when the plug is inserted into the socket, the end socket/plug is broken or falls off after the lower edge of the second shell meets the end socket/plug, and the glue flows out from the liquid outlet. The lower edge of the second shell can also be provided with a notch to better apply external force to the seal head/plug.

The lead is connected with the pin assembly/the socket assembly through the first protective sleeve and the second protective sleeve. After the glue is cured, the bottom ends of the pin assemblies and the bottom ends of the jack assemblies are both packaged in the cured glue, if the operations such as wire replacement and the like are really needed in the later period, the glue in the first protective sleeve or the second protective sleeve can be broken, so that the bottom ends of the pin assemblies or the bottom ends of the jack assemblies are exposed for wire replacement and the like, and the connector can be repaired or maintained to a certain extent.

The second protective sleeve has a tubular extension 61 for wrapping the wire, and the inner diameter of the tubular extension is larger than the outer diameter of the wire; the tubular extension is used for containing excessive glue to prevent overflow, and the glue entering the tubular extension is not excessive, but fills a gap between the lead and the second protective sleeve after the glue is cured to form sealing protection.

Among the first mounting panel and the second mounting panel, be equipped with a plurality of through-holes on the second mounting panel at least. After being released, the glue enters the first protective sleeve and the second protective sleeve through the through holes.

As shown in fig. 4, the left liquid storage part and the right liquid storage part are formed by separating the inner cavity of the first shell by a partition plate 18; the liquid outlet mouths of the left liquid storage part and the right liquid storage part are arranged close to each other.

The liquid outlet axes of the left liquid storage part and the right liquid storage part are crossed, and the focus is positioned on the inner side of the first protective sleeve. When the head/end cap is opened, glue sprayed from the liquid outlets of the left liquid storage part and the right liquid storage part is intersected at one position to obtain preliminary mixing, which is favorable for improving the mixing efficiency. In addition, the liquid outlets of the left liquid storage part and the right liquid storage part can share one sealing head/plug so as to further ensure that the liquid outlets of the left liquid storage part and the right liquid storage part can be opened simultaneously.

Be equipped with a slide bar 7 in the second protective sheath, second shell inner wall is equipped with stirring ring 8, and the slide bar is connected with the movable pulley, and the stirring ring slides from top to bottom along the second shell under the drive of slide bar in order to play the stirring effect.

The sliding rod is fixedly connected with the middle of the sliding wheel, a plurality of supporting spokes are arranged in the sliding wheel, the supporting spokes are straight or arc-shaped, and the supporting spokes avoid the arrangement of the jack component. When the sliding wheel and the supporting spokes thereof move up and down, the A component and the B component of the AB glue are uniformly stirred to promote the solidification. A handle 71 can be arranged at the head of the outer side of the sliding rod to facilitate the pulling of the sliding rod; in order to reduce the friction of the sliding rod on the wire harness, a sliding sleeve can be arranged on the sliding rod.

Example 2

s1, respectively connecting a pin assembly and a jack assembly with a lead, and enabling a first protective sleeve to be in sealing connection with the lead so as to prevent glue from flowing out of the lower side of the first protective sleeve; the first protective sleeve can be hermetically connected with the conducting wire by arranging a rubber sealing ring, a heat shrinkable tube, adding fillers and the like;

and S4, after the glue enters the tubular extension part of the second protective sleeve, pulling the sliding rod to enable the sliding wheel to slide up and down, stirring and uniformly mixing the AB glue, and standing and curing. Due to the characteristics of the AB glue, the environment temperature is preferably over 25 ℃ during curing, and if the environment temperature is lower, auxiliary means such as a hair drier and the like can be adopted for heating.
