Abstract

A protective cover structure for a waterproof connector comprises a connector sequentially formed with a connecting pipe, a locking seat and a plug tube. The locking seat is recessed with a tight groove facing the direction of the plug tube, and an outer surface of the plug tube is recessed with a dodge slot. The protective cover is connected with a gasket and a cover body by an interconnecting strap, and the gasket is sleeved on the plug tube and installed in the tight groove so that the torsion force generated when the assembly is locked will not cause the distortion of the gasket and thus the waterproof function of the gasket will not be lost. Furthermore, the interconnecting strap is accommodated in the dodge slot. The interconnecting strap is hidden without affecting the external penetration of the plug tube so that it will not constitute the assembly interference. In addition, the cover body clamps and fixes the plug tube with an outer ring portion and an inner ring portion in an inner and outer shape, thereby having a dustproof function. A plurality of pins are inserted between the connecting pipe and the plug tube, the plate-shaped outer edge of the locking seat is formed with a convex ring, and the tight groove facing the direction of the plug tube is surrounded by the convex ring. The plug tube is concavely formed with an accommodating space so that the pins are protruded in the accommodating space and the plug tube can be inserted to connect the pins so as to form a power supply and communication function. The inner ring portion is formed with an inwardly contracted plane, and the inwardly contracted plane avoids the protruding bar formed in an inner surface of the plug tube to have the relative anti-rotation effect of the cover body and the plug tube.

Description

Protective cover structure of waterproof connector

The present invention relates to a connector protection structure, in particular to a protection cover structure of a waterproof connector with both waterproof and dustproof functions.

According to a conventional connector protection cover structure, as shown in Figure 10, it includes a connector 40, a protection cover 50 and an electrical device 60. The connector 40 is formed with a socket 41 and a fixing plate 42 in sequence. And a connecting end 43. The outer surface 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 penetrated at the through hole 421. The protection The cover 50 is connected to one end of a connecting band 51 with a gasket 52, and the other end is connected to a cover 53. The gasket 52 is provided with a perforation 521, and the perforation 521 is sleeved on the connecting end 43, and the gasket 52 corresponding to the through hole 421 is provided with a plurality of circular holes 522, and the connecting belt 51 is formed with a groove 511 where the gasket 52 is connected, so that the connecting belt 51 can be elastically deformed at the groove 511 to make the cover The body 53 covers the socket 41, and the inner edge of the cover body 53 is protruding with a convex ring 531, so that the convex ring 531 is engaged with the groove 411 of the socket 41 to form a dustproof cover, and the connector 40 uses the The connecting end 43 passes through the locking hole 61 of the electrical device 60, so that the gasket 52 of the protective cover 50 is sandwiched between the fixing plate 42 and the electrical device 60, and then the connector 40 is locked with bolts 44. The protective cover 50 and the protective cover 50 are both fixed on the housing of the electrical device 60. Although the protective cover 50 has the function of covering the connector 40 to prevent dust, it is not difficult to find that there are still some shortcomings in the above-mentioned conventional structure. The main reasons are as follows:

(1) The gasket 52 only covers the connecting end 43 of the connector 40 with the through hole 521, And match the bolt 44 through the round hole 522 to form a fixed position of the connector 40 and the washer 52. When the housing of the electrical device 60 is locked, the washer 52 will easily deviate, and because of the bolt 44 It is locked and clamped between the fixing plate 42 and the housing of the electrical device 60 to produce distortion and deformation, so that the gasket 22 and the housing of the electrical device 60 form an uneven surface contact, thus affecting the waterproof effect of the gasket 52. The gap formed by the gasket 52 on the outside and the housing of the electrical device 60 is also easy to accumulate moisture and penetrate into the electrical device 60.

(2) The connector 40 is elastically clamped to the electrical device 60 with only the gasket 52. If the locking force is insufficient, the connector 40 will easily loosen, and if the locking force is too large, the gasket 52 will twist The amount of deformation and the amount of extrusion deformation will increase. The lighter one will cause uncertainty in the degree of locking and waterproof effect, and the serious one may cause damage to the gasket 52. Excessive extrusion will also reduce the durability of the gasket 52.

(3) The inner edge of the cover body 53 is tightly fitted with the outer edge of the socket 41, making it difficult for the air inside the cover body 53 to be discharged, causing the cover body 53 to generate air chambers and causing resistance when closing. There is a problem that it is difficult to cover, and the cover 53 does not limit the angular position of the socket 41, so the connecting belt 51 will be bent and twisted at the same time, and the connecting belt 51 is formed at the groove 511. The thin position makes the connecting strap 51 easy to twist off from the groove 511, resulting in the disadvantage of insufficient durability of the connecting strap 51.

In view of this, the inventor of the present invention has been engaged in the manufacturing, development and design of related products for many years. Aiming at the above-mentioned goals, after detailed design and careful evaluation, he finally obtained a practical invention.

The technical problem to be solved by the present invention lies in the above-mentioned existing technology Missing, a protective cover structure for waterproof connectors is provided.
