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. 1-3, a self-sealing type automobile connector comprises a plug 2 and a socket 1 which are matched with each other, 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 at 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 pressure of the compressed gas should not be too high 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 glue can be filled with air at all positions of the connector but cannot overflow (for example, the glue is filled into the tubular extension part), the quantity of the compressed gas is controlled to be expanded after the glue is extruded out of the interlayers, so that the compressed gas is preferably not flushed out of the inner cavity between the interlayers or only a small amount of compressed gas is flushed out, and the packaging and moisture-proof effects are not influenced even if a certain amount of bubbles are arranged inside the glue after solidification; if more compressed gas is flushed into the inner cavity, the gas can be floated and overflow by slight vibration.
The lower part of the inner side of the first shell is provided with at least one liquid outlet 16, and the liquid outlet is provided with an end enclosure 17 protruding from the surface of the inner side of the first shell; if the end socket is adopted, a thinner or 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 plug comprises a second mounting plate 21 and a second shell 22 matched with the inner side space of the first shell, a second opening 23 is formed in the bottom of the second shell, and the second mounting plate is fixed at the bottom of the inner side of the first shell or the second opening; 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 first mounting plate is provided with a contact pin assembly 3, and the second mounting plate is correspondingly provided with a socket assembly 4; the bottom ends of the pin assembly and the socket assembly are used for being connected with a lead A; the first mounting plate is used for fixing the pin assembly, after the first mounting plate is connected and fixed with the first shell, the position of the pin assembly can be fixed according to the design, and the function of the second mounting plate is also the same; therefore, when the plug is inserted into the socket, the pin assemblies can be smoothly inserted into the socket assemblies in a one-to-one correspondence manner to form electric connection; after the glue is cured, an insulating filling can be formed between the jack assemblies, and if necessary (for example, when a high-voltage connector is produced), an insulating layer can be arranged outside each jack in the jack assemblies to improve the insulating effect.
When the plug is completely inserted into the socket, the second shell jacks the end socket/plug so as to enable the glue to flow out.
The bottom end 31 of the pin assembly is exposed out of the bottom of the outer side of the first shell;
the bottom end 41 of the jack assembly is exposed at the bottom of the outside of the second housing. The bottom of the outer side of the first shell is provided with a first protective sleeve 5, and the bottom end of the pin assembly/socket assembly is arranged in the first protective sleeve; correspondingly, a second protective sleeve 6 is arranged at the bottom of the outer side of the second shell, and the bottom end of the jack component/pin component is arranged in the second protective sleeve; 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 is provided with a transparent tubular extension part 61 used for wrapping the lead, and the inner diameter of the tubular extension part is larger than the outer diameter of the lead; 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.
The glue is a light-cured glue with good fluidity; the instant adhesive is more convenient to cure, but the instant adhesive generally has poor water resistance and poor cohesiveness when the adhesive film is thick, so that the instant adhesive is not suitable for use occasions of the invention; the glue cured by heating is simple to cure, but in actual operation, the connector is difficult to be heated for a long time at a high temperature, and the glue is inconvenient to use in actual use; therefore, the light-curing glue which can be cured in a short time is a feasible choice, and although the light-curing glue seems to be high in cost at first glance, the light-curing glue is cheap because other properties of the glue do not need to be considered too much.
The outer side of the first shell is sleeved with a dark color/light-tight protective film which is easy to tear off or the first shell is made of dark color/light-tight materials.
A small amount of reflective sheets are mixed in the glue. In this embodiment, the reflector is an insulating scale-type glass reflector or a plastic reflector, and the reflector can increase the reflection of ultraviolet light during photocuring and reduce the occurrence of curing dead angles such as the connection points of the pin assembly and the socket assembly.
The second housing is made of a low-refractive-index transparent material, for example, a material similar to a diffusion plate or a light guide plate, so as to have a good uniform diffusion effect on ultraviolet light during photocuring. Because the second shell can hold more glue, and the penetrability of ultraviolet ray is not strong, when the ultraviolet curing, should try hard to increase the solidification effect with every department of ultraviolet ray equipartition to the second shell like this, shorten curing time.
The lower end face of the second housing is exposed out of the second mounting plate, and a plurality of irradiation blind hole sites 24 are arranged on the lower end face. During curing, the ultraviolet LED lamp is aligned to the blind hole position to be polished, and the irradiation angle is properly changed, so that a better curing effect can be obtained.
And a UV reflecting layer is arranged on the inner side wall of the first shell. The UV reflecting layer can improve the reflectivity of ultraviolet rays and enhance the photocuring effect. Of course, the effect of complete curing can be achieved only by ultraviolet lamp irradiation, the curing time is only slightly long, individual curing dead angles occasionally exist, and the UV reflecting layer can be omitted due to cost.
The invention adopts more transparent materials, and the whole connector can have stronger industrial aesthetic feeling after the solidification is finished.
Example 2
A use method of a self-sealing type automobile connector comprises the following steps:
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;
s2, placing the first shell opening of the socket upwards, tearing off the protective film when the protective film is formed, enabling the compressed gas to be gathered at the upper part of the inner cavity, and standing for several seconds to reduce bubbles in the glue;
s3, inserting a second shell port of the plug downwards to be aligned with the socket (positioning holes and positioning columns can be respectively arranged on the plug and the socket to facilitate alignment), inserting pin assemblies and jack assemblies into one another, ejecting glue out after the end part of the end socket/plug is jacked open by the second shell, and filling gaps at the inner sides of the first shell and the second shell;
and S4, after the glue enters the tubular extension part of the second protective sleeve, curing the glue by adopting an ultraviolet lamp. During curing, the glue in the first protective sleeve and the second shell is cured preferentially, and then the glue in the second protective sleeve and the tubular extension part thereof is cured.
Example 3
As shown in fig. 4, similar to embodiment 1, the difference is that a plurality of optical fibers 7 with different lengths are arranged in the second protective sheath, one end of each optical fiber is exposed to the tubular extension and forms a light source irradiation end 71, and the other end of each optical fiber passes through the second mounting plate and enters the hollow part of the second housing.
The end points 72 of the plurality of optical fibers form a high-low arrangement in the second housing so that ultraviolet light can irradiate each point during curing;
when the number of the pin inserting assemblies is small, the plurality of optical fibers can be arranged in a straight line perpendicular to the second mounting plate; when the quantity of contact pin subassembly is more, for avoiding optical fiber to influence to insert and close, can set up many optical fiber spiral coils second shell inner wall.
