Description

Electronic equipment, surveillance cameras and sealed enclosures

The invention relates to a sealed component, in particular to a sealed housing, and electronic equipment and surveillance cameras using the sealed housing.

In order to make electronic equipment suitable for harsh environmental conditions such as underwater, high humidity, corrosive gases, corrosive liquids (such as acidic or alkaline liquids), and dust, most of the housings have a sealed structure, thereby avoiding water, gas, External impurities such as corrosive gases and dust enter the electronic equipment.

In general sealing structures, sealing elements (such as rubber rings or silicone rings) are usually arranged at the joints between the shells to form a sealed internal accommodation space. Related related cases include the Republic of China Invention Patent Bulletin No. I574601 "Waterproof casing and method for manufacturing waterproof casing".

However, such a sealed structure is only suitable for a case where the electronic device is completely contained in a sealed space, and is not suitable for storing an electronic device having a transmission line. For this reason, although there are related technologies such as "A waterproof structure of a cable led out from the side of a waterproof casing of a digital video camera" of China Utility Model Patent Publication No. CN206100218.

However, the above-mentioned CN206100218 sealing structure design still does not easily produce a sufficient sealing effect. The reason is that most of the transmission line has a soft insulation layer on the outer layer, and the transmission line is often bent due to the use requirements. These conditions cause the waterproof plug to not easily adhere to the transmission line and cause a gap.

Therefore, in order to make the sealing structure suitable for an electronic device having a transmission line, the inventor proposes a sealed housing for accommodating an electronic device. The sealed housing includes a housing body and a sealing component. The accommodating body is used for accommodating the electronic device, and a transmission line of the electronic device is allowed to pass through. The sealing assembly includes a water stop ring and an abutment member, and the water stop ring and the abutment member are sleeved on the transmission line. The water stop ring is located between the accommodation body and the abutment member, and the accommodation body Or / and the abutting member has a pressing ring surface inclined at the corresponding water-stop ring; when the abutting member is assembled in the containing body, the abutting member squeezes the water-stop by the pressing ring surface Ring, so that the water stop ring tightens the transmission line.

The invention also relates to an electronic device with a sealed housing, comprising: an electronic device and a sealed housing. The electronic device has a transmission line. The sealed housing includes a receiving body and a sealing component. The receiving body is used for containing the electronic device and allowed to pass through the transmission line. The sealing component includes a water stop ring and an abutment member. The water stop ring And the abutment piece is sleeved on the transmission line, the water stop ring is located between the accommodating body and the abutment piece, and the accommodating body or / and the abutment piece is inclined at one of the corresponding water stop rings Compressing the annular surface; when the abutting member is assembled in the accommodating body, the abutting member presses the water retaining ring by the pressing annular surface, so that the water retaining ring tightens the transmission line.

Further, the receiving body has a groove at the exit of the transmission line; the sealing assembly further includes a locking member, the locking member has a through hole, the through hole is for the transmission line to pass through, and the locking member is screw-locked In the groove, one end of the locking member pushes the abutting member to displace, so that the abutting member presses the water stop ring.

Further, the abutting member has a recessed groove on a side corresponding to the water retaining ring, and the pressing ring surface surrounds the recessed groove and corresponds to the water retaining ring to squeeze at least a part of the water retaining ring into the concave groove.

Further, the recessed groove has a chamfer at one of the openings to which the recessed groove belongs, and the recessed groove has another chamfered adjacent to the through hole, and the aforementioned chamfers all form the aforementioned compression ring surface.

Further, the receiving body has a groove at the exit of the transmission line; the sealing assembly further includes a lock member, the lock member has a through hole, the through hole is used for the transmission line to pass through, and the lock member is used for screwing The lock is locked in the groove, and the lock member and the abutment member are integrally formed.

The invention is also a surveillance camera, comprising: an image capture module, a transmission line and a sealed casing. The transmission line is connected to the image capture module. The sealed housing includes a housing body and a sealing assembly. The housing body includes a main housing, a lens cover and a rear cover. The lens cover and the rear cover are respectively locked at a front end of the main housing and A rear end, a first water stop ring between the lens cover and the front end, a second water stop ring between the rear cover and the rear end, the image capture module is installed in the main housing, and the The transmission line passes through the back cover. The seal assembly includes a water stop ring and an abutment member. The water stop ring and the abutment member are sleeved on the transmission line. The water stop ring is located on the back cover and the abutment member. In between, the back cover or / and the abutment member has a pressing ring surface at an angle corresponding to the water stop ring; when the abutment member is assembled on the back cover, the abutment member uses the pressing ring surface. The water stop ring is squeezed, so that the water stop ring tightens the transmission line.

According to the above technical features, the following effects can be achieved:

1. Squeeze the water stop ring by the inclined compression ring surface, so that the water stop ring can tighten the transmission line, which can effectively avoid the gap around the transmission line, so as to prevent water, corrosive gas, dust and other external impurities from entering the electronic equipment. Inside, which improves the durability of electronic equipment.

2. The abutment can be pushed by the thread feed of the screw lock, so that the abutment can be stably translated and squeezed against the water stop ring to avoid torsional deformation of the water stop ring.

3. The sealing ring and abutment of the sealing component can be located in the groove of the receiving body, which can prevent the sealing ring from being directly exposed to external influences and damage, and can also prevent the sealing component from affecting the overall appearance.

4. The abutment piece can be formed with a recessed groove, so that the water stop ring will be deformed when it is squeezed into the recessed groove, filling the gap of the recessed groove to further improve the sealing effect.

5. The contact piece can also be integrated with the lock piece to simplify the required parts.

6. The compression annulus can be provided by the abutment, but it can also be provided by the containing body, which is not limited in implementation. The main purpose is to generate an inward compression force on the water stop ring.
