Abstract

The utility model discloses a coupler with a waterproof structure. The coupler comprises a cavity and a cover plate connected with the cavity in a covering manner, wherein the central part of the insulator of a connector is provided with a flange, the connector is connected with the cavity via the flange, the insulator is provided with an annular waterproof groove, an annular sealing ring is in muff coupling in the annular waterproof groove, the annular waterproof groove is arranged at the connection part of the flange and the insulator and is positioned at the inner side of the flange, the inner side surface of the cover plate is provided with a lug boss protruding toward the inner cavity of the cavity, the periphery of the root part of the lug boss is provided with the waterproof groove, and a sealing rubber ring is embedded in the waterproof groove. The coupler with the waterproof structure can well guarantee the stability of a product used outdoors and prolong the service lifetime of the product.

Description

Coupler with waterproof construction
Technical field:
The utility model relates to a kind of coupler with waterproof construction, belongs to technical field of micro communication.
Background technology:
Coupler is widely applied in technical fields such as microwave communication, electronic countermeasures and radars, and reliability of products, stability and high performance-price ratio are very important.Popularization along with range of application, the coupler product is more and more worked under the environment of some inclement conditions, for example moist, warm southern weather, product can be because the influence of environment reduces its useful life, so how deal with the influence of adverse circumstances, prolong its working life and become a technical problem that needs to be resolved hurrily by the improvement of product.Product major part in the market all can not be used for outdoor use, because its product inside does not solve the problem of waterproof.The long-term use in the middle of moist, warm environment of product will be damaged, and greatly reduces the useful life of product.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of coupler with waterproof construction, by in the inner minimum space of coupler product, having increased waterproof construction, promptly can well guarantee the stability when product uses out of doors, prolong the useful life of product, do not bring the significantly increase of product cost again, effectively raise cost performance of product.
The utility model technical solution problem adopts following technical scheme:
Coupler with waterproof construction, described coupler has cavity, covers the cover plate that is connected on the described cavity, the middle part of the insulator of connector is provided with flange, described connector is connected on the described cavity by flange, offer annular capillary groove on the described insulator, be socketed with O-ring seal in described annular capillary groove, described annular capillary groove is located at the junction of described flange and described insulator and is positioned at the inboard of described flange; The medial surface of described cover plate is provided with the boss to the inner chamber protrusion of described cavity, is provided with capillary groove around the root of described boss, and embedding in described capillary groove has sealing rubber ring.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
Coupler of the present utility model is provided with the boss that protrudes to the cavity inner chamber in the bottom surface of cover plate, is provided with capillary groove around the root of boss, and embedding in described capillary groove has sealing rubber ring.Described rubber seal forms sealing between the boss edge of cover plate bottom surface and cavity inner wall; The connector flange is inboard to be provided with annular capillary groove with the insulator junction, this annular capillary groove is opened on the circumference of insulator and is socketed with O-ring seal, this O-ring seal forms sealing between flange inner wall root and cavity inner wall, by this waterproofing design, improved the water resistance of coupler product greatly, made it can reach the classification of waterproof requirement of IP65 easily.
Description of drawings:
Fig. 1 is an overall structure schematic diagram of the present utility model; Fig. 2 is the structural representation of cover plate bottom surface; Fig. 3 is the structural representation of connector.
Number in the figure: 1 connector, 11 insulators, 12 flanges, 13 O-ring seals, 2 cavitys, 3 cover plates, 31 boss, 32 sealing rubber rings.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment:
Embodiment: referring to Fig. 1-3, the coupler of present embodiment, described coupler has cavity 2, cover plate 3 covers and is connected on the cavity 2, and can pass through screw, form the requirement that sealing reaches waterproof between cover plate 3 and the cavity 2 in order to make, shown in Figure 2, be provided with the boss 31 that the inner chamber to cavity protrudes in the bottom surface of cover plate 3 (being medial surface), be provided with capillary groove around the root of boss 31, sealing rubber ring 32 be socketed in boss around and be partially submerged in the capillary groove, when cover plate 3 covers when being connected on the cavity 2, sealing rubber ring is at the boss edge, form sealing between cover plate bottom surface and the cavity inner wall.
Referring to Fig. 3, the middle part of the insulator 11 of connector 1 is provided with flange 12, described connector 1 is connected on the described cavity 2 by flange 12, on insulator 11, offer annular capillary groove, this annular capillary groove is located at the junction of flange 12 and insulator 11 and is positioned at the inboard of flange, in described annular capillary groove, be socketed with O-ring seal 13, when flange 12 by screw on cavity 2 time, O-ring seal 13 forms the purpose that sealing reaches waterproof between inboard root of flange and cavity inner wall.Guaranteed that product has reached the IP65 classification of waterproof when using out of doors, improved reliability of products, fail safe, prolonged the useful life of product.
