Description

Light small-volume waterproof connector

Technical Field

The invention relates to the technical field of plug connectors, in particular to a light small-volume waterproof plug connector.

Background

Connectors, also known as connectors, are used to connect two active devices to transmit current or signals. The connector comprises a socket and a plug, and the socket and the plug are butted to realize the transmission function of current or signals.

When the connector is applied to an underwater unmanned underwater vehicle or a water-air dual-purpose aircraft, the connector needs to be in a waterproof design. The existing waterproof design mainly achieves the waterproof effect by adding a sealing ring and a sealant at a connector interface, and the waterproof connector is complex in structural design, high in cost, heavy in mass and large in size. For these small underwater devices, the overall weight and the internal space are very tight. On the basis of meeting the waterproof sealing requirement, a connector with simple structure, lighter weight and smaller volume is often needed.

Disclosure of Invention

The invention aims to provide a light small-volume waterproof connector, which solves the problems of complex sealing structure and heavy weight of the interface of the existing connector.

In order to achieve the purpose, the technical scheme of the invention is as follows: the utility model provides a waterproof connector of light small dimension, includes socket, plug and protective sheath, be equipped with the jack on the socket, the symmetry is equipped with the connecting rod with jack matched with on the plug, the protective sheath cladding is in the outside of plug, the one end fixed connection of protective sheath is on the plug, the plug is stretched out to the other end of protective sheath, the size of protective sheath slightly is less than the size with the plug connection department on the socket.

The principle and the effect of the technical scheme are as follows: in the scheme, the socket and the plug can be tightly connected together by utilizing the jacks on the socket and the connecting rods on the plug; meanwhile, the joint of the jack and the connecting rod can be protected from water by using a protective sleeve outside the plug.

Further, the protective sleeve is made of an elastic waterproof material.

Further, the protective sleeve is made of rubber.

Through the setting, can carry out the cladding to the gap of junction on jack and the connecting rod with the help of the protective sheath, played waterproof and sealed effect, rubber belongs to conventional material again simultaneously, is favorable to reducing the cost of this product.

Compared with the prior art, the beneficial effect of this scheme: the waterproof structure has good waterproof effect, simple structure, small volume, light weight and wide market popularization value; meanwhile, the external hanging load capacity and the space utilization rate of the underwater unmanned equipment are improved.

Drawings

FIG. 1 is a schematic view of a light-weight, small-volume, waterproof connector according to the present invention in a plugged state;

fig. 2 is a schematic view showing a structure of a lightweight and small-sized waterproof connector in a separated state according to the present invention.

Detailed Description

The present invention will be described in further detail below by way of specific embodiments:

reference numerals in the drawings of the specification include: socket 1, plug 2, protective sheath 3, jack 4, connecting rod 5.

Examples

As shown in figures 1 and 2: the utility model provides a waterproof connector of light small dimension, includes socket 1, plug 2 and protective sheath 3, and socket 1's right-hand member adopts the trapezium structure, and socket 1's right-hand member is opened has jack 4. The left side of the plug 2 adopts a trapezoidal structure which is the same as that of the socket 1, the left end of the plug 2 is symmetrically provided with a connecting rod 5 which is matched with the jack 4, and the connecting rod 5 and the plug 2 are manufactured in an integrated manner, so that the strength of the connecting rod 5 can be increased. The protective sheath 3 cladding is in the outside of trapezium structure on plug 2, and the right-hand member adhesion of protective sheath 3 is on plug 2, and the left end of protective sheath 3 surpasss the left end of plug 2, and can cover the trapezoidal region of socket when plug 2 is connected with socket 1, and the size that corresponds the region on the size ratio socket 1 of protective sheath 3 is slightly littleer to enable protective sheath 3 tightly detain outside socket 1, protective sheath 3 is made by rubber.

When the plug is used, the trapezoidal structures on the plug 2 and the socket 1 are convenient for an operator to carry out plugging operation, and the operator inserts the connecting rod 5 on the plug 2 into the jack 4 on the socket 1, so that the socket 1 and the plug 2 are tightly connected together; meanwhile, the joint of the jack 4 and the connecting rod 5 can be protected from water by using the protective sleeve 3 outside the plug 2. When the plug connector is not used, the protective sleeve 3 can be rolled outside the plug 2, so that the plug connector is convenient to use next time.

The foregoing are merely examples of the present invention and common general knowledge of known specific structures and/or features of the schemes has not been described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
