Description

Waterproof connector with protective cover

The present invention relates to a connector protection structure, and more particularly to a waterproof connector with a protective cover that has both waterproof and dustproof functions.

A connector protection cover structure, as shown in FIG. 10, includes a connector 40, a protection cover 50 and an electrical device 60. The connector 40 is sequentially formed with a socket 41 and a fixing plate 42. And a connecting end 43, the outer surface ring of the socket 41 is provided with a plurality of grooves 411, and the fixing plate 42 is provided with a plurality of through holes 421, and a bolt 44 is disposed at the through hole 421. The cover 50 is connected to the end of the connecting strip 51 with a spacer 52, and the other end is connected with a cover 53. The spacer 52 defines a through hole 521, and the through hole 521 is sleeved on the connecting end 43. A plurality of circular holes 522 are defined in the through hole 421, and a groove 511 is formed in the connecting tape 51 at the connecting hole 52, so that the connecting tape 51 can be elastically deformed at the groove 511 to cover the cover. The body 53 covers the socket 41, and a convex ring 531 is protruded from the inner edge of the cover 53 to engage the recess 411 of the socket 41 to form a dustproof function. The connecting end 43 is disposed through the locking hole 61 of the electrical device 60, so that the spacer 52 of the protective cover 50 is sandwiched between the fixing plate 42 and the electric The connector device 60 is locked by the bolts 44 to fix the connector 40 and the protective cover 50 to the outer casing of the electrical device 60. Although the protective cover 50 has the function of covering the connector 40 to achieve dust prevention, It is not difficult to find out that there are still some shortcomings in the above-mentioned conventional structure. The main reasons are as follows:

(1) The spacer 52 is only sleeved with the connecting end 43 of the connector 40 by the through hole 521, And the bolt 44 is inserted through the circular hole 522 to form a fixed position of the connector 40 and the gasket 52. When the outer casing of the electrical device 60 is locked, the gasket 52 will be easily offset, and because of the bolt 44 The locking member is twisted and deformed between the fixing plate 42 and the outer casing of the electrical device 60, so that the gasket 52 forms a non-flat surface contact with the outer casing of the electrical device 60, thereby affecting the waterproof effect of the gasket 52. The gap formed between the outer gasket 52 and the outer casing of the electrical device 60 is also likely to accumulate moisture and penetrate into the interior of the electrical device 60.

(2) The connector 40 is elastically clamped to the electrical device 60 only by the spacer 52. If the locking force is insufficient, the connector 40 will be easily loosened, and if the locking force is too large, the spacer 52 is distorted. The amount of deformation and the amount of extrusion deformation will increase, and the uncertainty of the degree of locking and the waterproof effect may be caused by the lightness, and the gasket 52 may be damaged seriously. Excessive extrusion may also reduce the durability of the gasket 52.

(3) The inner edge of the cover 53 is tightly fitted with the outer edge of the socket 41, so that the air inside the cover 53 is difficult to be discharged, so that the cover 53 generates a gas chamber and causes resistance during the cover. There is a problem that it is difficult to cover, and the cover 53 does not limit the angular position of the socket 41. Therefore, the connecting belt 51 will be deformed by bending and torsion at the same time, and the connecting belt 51 forms the most at the groove 511. The thin position makes the connecting belt 51 easily broken by the groove 511, resulting in the disadvantage that the connecting belt 51 is insufficient in durability.

In view of this, the inventors have been engaged in the manufacturing development and design experience of related products for many years, and after detailed design and careful evaluation of the above objectives, the present invention has finally become practical.

The technical problem to be solved by the present invention lies in the above-mentioned existing Missing, providing a waterproof connector with a protective cover.
