Waterproof jacket

The invention relates to a communication device, in particular to a waterproof sheath of a communication device.

Generally, communication devices used outdoors must have a high level of waterproofing to prevent electronic components in the casing of the communication device from being defeated or short-circuited due to rain or moisture. The housing of the general communication device includes a plurality of input/output (I/O) interfaces for mating with the connector of the transmission line to realize connection of the communication device with other communication devices.

At present, a waterproof solution at the input and output interface of the casing is achieved by inserting a sealing coil between the transmission line and the interface to achieve a waterproof function. However, in this waterproof method, a special tool is required to uniformly press the sealing coil into the reserved space of the interface, and the tolerance is precisely controlled. Otherwise, the sealing coil is easily broken and loses the waterproof function. Therefore, the structure that realizes the waterproof function through the sealed coil is inconvenient to assemble, and is also disadvantageous for large-scale applications.

In view of this, it is necessary to provide a waterproof jacket which is applied to a through hole of a casing through which a transmission line of a communication device passes, and the waterproof sheath is convenient to install and at the same time achieves a waterproof effect.

The waterproof sheath of the present invention is applied to a communication device. The communication device includes a casing, and the casing is provided with a first through hole, and the transmission line passes through the first through hole, and the waterproof sheath is disposed on the outer surface of the casing at the first through hole. The waterproof jacket includes a sleeve, an elastic waterproof member, and a cover. The middle of the sleeve There is a receiving cavity to communicate with the first through hole. The elastic waterproof component is received in the receiving cavity and wound on the transmission line. The cover sleeve is sleeved on the periphery of the transmission line and cooperates with the sleeve to block the receiving cavity. One end of the elastic waterproof member is fixed to the cover plate, and the other end is abutted against the casing. Rotating the cover plate, the elastic waterproof member is radially tightly wound on the transmission line, and pressing the cover plate toward the casing axially compresses the elastic waterproof member, so that the waterproof sheath is in the first pass A seal is formed between the hole and the transmission line in both the radial direction and the axial direction.

Compared with the prior art, the waterproof sheath of the present invention is wound around the transmission line and received in the receiving cavity of the sleeve through the spiral-shaped elastic waterproof element, and rotates and compresses the elastic waterproof element by the cooperation of the cover plate and the sleeve. The waterproof jacket forms a seal between the through hole of the casing and the transmission line, so that the through hole of the transmission line achieves a good waterproof effect. The waterproof jacket has a simple structure and good water resistance, and can be quickly installed by hand, which greatly reduces the cost and is advantageous for large-scale applications.

Please refer to FIG. 1 , FIG. 2 and FIG. 3 at the same time. The communication device 100 of the present invention includes a casing 10, a circuit device 20 housed in the casing 10, a transmission line 30, and a waterproof sheath 40 disposed on the casing 10.

When the elastic waterproof member 42 is tightened, an axial pressure F2 is applied toward the casing 10, and the cover plate 43 is pressed to axially compress the elastic waterproof member 42 and the plurality of the sleeve 41 is convex. The block 51 passes through the plurality of second grooves 612 of the cover plate 43 respectively, and then rotates the cover plate 43 so that the plurality of blocks 61 of the cover plate 43 respectively interfere with the plurality of the protrusions 51 of the sleeve 41 to cover the cover plate. 43 is fixed in the sleeve 41. Under the action of the axial pressure F2, the inclined faces of the spiral body of the elastic waterproof member 42 are pressed tightly together to produce a second water sealing surface M2 (as shown in Figs. 4 and 6). The axial pressure F2 is released, and the cover plate 43 is subjected to the axial resilience of the elastic waterproof member 42 , and the plurality of first abutting top portions 611 of the cover plate 43 respectively abut against the inner wall of the plurality of bumps 51 of the sleeve 41 . The equal protrusions 51 are respectively blocked by the second abutting tops 612 (as shown in FIG. 5 ), so that the waterproof sheath 40 is radially between the first through holes 11 of the casing 10 and the transmission line 30 . A seal is formed both in the axial direction.

In the present embodiment, the bottom of the peripheral wall 412 of the sleeve 41 is provided with a drain hole 4121 to discharge the accumulated water between the elastic waterproof member 42 and the sleeve 41 out of the sleeve 41.

Please refer to Figure 7. In the present embodiment, the connector size of the two ends of the transmission line 30 is larger than the outer diameter of the first through hole 11 of the casing 10. The casing 10 includes a pair of lids 12 that are sealingly connected by a sealing coil 14 to form a receiving space. The circuit device 20 is housed in the accommodating space. Each cover 12 is formed by a bottom wall 121 and a side wall 122 to form a top opening structure. The sleeve 41 of the waterproof sheath 40 includes a pair of engaging portions 414 protruding from the side walls 122 of the pair of covers 12 respectively. The first through hole 11 of the casing 10 includes a pair of recesses 112 respectively disposed at the top of the side walls 122 of the pair of covers 12. When the pair of covers 12 are sealed and connected The pair of engaging portions 414 are coupled to each other to form the sleeve 41. The pair of recesses 112 are coupled to each other to form the first through hole 11. During assembly, the transmission line 30 is directly inserted into the recess 112 of the side wall 122 of one of the pair of covers 12, and the pair of covers 12 are engaged to pass the transmission line 30 through the first through hole 11 of the casing 10. The transmission line 30 is received in the second through hole 432 of the cover plate 43 and the elastic waterproof member 42 is wound around the transmission line 30, and the cover plate 43 is engaged with the sleeve 41 to realize the installation of the waterproof sheath 40.

The waterproof sheath provided by the invention is provided with a sleeve through a through hole of a casing passing through a transmission line of the communication device, and one end of the spiral elastic waterproof member is fixed on the cover plate, and the elastic waterproof member is wound around the transmission line and accommodated In the receiving cavity of the sleeve, the waterproof sheath can be quickly installed at the through hole of the transmission line of the casing by manually rotating the cover plate and pressing the elastic waterproof component, so that the waterproof sheath is in the first through hole and The transmission line forms a seal between each other, which is convenient to operate and can achieve a good waterproof effect, and is advantageous for large-scale applications.
