Connecting assembly and camera

Technical Field

The application relates to the technical field of electronic equipment, in particular to a connecting assembly and a camera.

Background

In practical applications of the camera, the camera is usually connected with an external device through a cable; for example, in order to meet the power supply requirement, the camera needs to be electrically connected with an external power supply device through a cable; or, in order to realize the signal transmission requirement, the camera needs to be connected with an external network device through a network cable, and in particular, in order to realize the connection of the camera with the external network device, the camera usually includes a tail cable exposed outside the camera, an interface (such as an RJ45 interface) is provided at an end of the tail cable, and a connector (such as an RJ45 connector) of the external network cable is plugged into the interface at the end of the tail cable of the camera, so that the connection of the camera with the external network device (or the external network cable) can be realized.

When the camera is applied to an outdoor environment, in order to enable the camera to have a certain waterproof function, a waterproof joint can be arranged at the joint of the tail wire and the network cable; after the interface is inserted into the connector, the waterproof connector sleeved on the interface and the waterproof connector sleeved at the connector can be screwed to realize airtight connection, so that the waterproof performance of the interface and the connector is improved. In the installation process, in order to ensure that the waterproof joints are screwed in place, a mark silk screen or a mark line and the like are usually respectively arranged at the two waterproof joints, and when the two waterproof joints are screwed in place, the mark lines on the two waterproof joints can be aligned, so that whether the two waterproof joints are screwed in place can be judged by observing whether the mark lines are aligned; in practice, however, during the construction process, the worker may forget to screw the two waterproof joints in place, which may not ensure the waterproof performance of the joints and the interface, and may cause the undesirable phenomena of water leakage, short circuit, metal corrosion, etc., and damage the equipment. However, at present, no effective means is available for remotely monitoring and detecting the installation condition of the waterproof joint, so that certain potential safety hazards exist.

Disclosure of Invention

The application provides a coupling assembling and camera that can carry out effective monitoring to waterproof assembly's installation condition.

In one aspect, embodiments of the present application provide a connection assembly including a first terminal at an end of a first cable and a second terminal at an end of a second cable; the first terminal includes: the waterproof device comprises a first connecting end and a first waterproof assembly wrapped on the periphery of the first connecting end; the second terminal includes: the second connecting end and a second waterproof assembly wrapped on the periphery of the second connecting end; the first connecting end and the second connecting end are detachably connected; the first waterproof component and the second waterproof component are detachably connected in a sealing manner; the first waterproof assembly comprises a first signal end and a second signal end which are electrically connected with the first cable, and the second waterproof assembly comprises a conductive end; after the first waterproof assembly and the second waterproof assembly are connected in a sealing mode, the conductive end is in short connection with the first signal end and the second signal end. Through detecting the on-off condition of the first signal end and the second signal end (whether the first signal end and the second signal end are short-circuited by the conductive end), whether the first waterproof assembly and the second waterproof assembly are correctly installed in place can be known, and whether the airtightness between the first connecting end and the second connecting end is effectively guaranteed can be judged.

In particular, the connection mode and the specific type of the first connection end and the second connection end can be various.

For example, the first connection end and the second connection end may adopt a plug-in connection manner; specifically, the first connection terminal may be an interface (e.g., an RJ45 interface), and the second connection terminal may be a connector (e.g., an RJ45 connector, commonly referred to as a crystal header), and the electrical connection between the first terminal and the second terminal can be achieved by inserting the connector into the interface.

In addition, in some embodiments, other types of interfaces may be used between the first connection end and the second connection end, a rotational connection manner (such as a threaded connection), or other connection manners, which is not specifically limited in this application.

In particular implementation, the connection mode and the specific type between the first waterproof assembly and the second waterproof assembly can be various.

For example, the first waterproof assembly and the second waterproof assembly can be connected in a rotating manner.

Specifically, the first waterproof assembly may include a substrate wrapped around the first connection end, and a first mating surface is disposed around the substrate; the first connection end can be located in the front face of the base body so as to facilitate connection with the second connection end. The second waterproof assembly can comprise a cylinder, and the rear end of the cylinder is sleeved on the periphery of the second cable and is in close fit with the periphery of the second cable; the front end of the cylinder body is provided with a second butt joint surface used for being in airtight butt joint with the first butt joint surface. When the base body and the cylinder body are screwed and fixed, the first butt joint surface and the second butt joint surface are combined in a sealing mode, and therefore sealing butt joint between the first cable and the second cable is achieved.

In specific implementation, in order to realize the rotary connection between the base body and the cylinder body, a screwing groove (or an external thread structure) can be arranged on the periphery of the base body, a protrusion (or an internal thread structure) which can be screwed into the screwing groove can be arranged on the inner wall of the cylinder body, and after the protrusion is completely screwed into the screwing groove, the first butt joint surface can be in tight butt joint with the second butt joint surface.

In addition, in some embodiments, in order to improve the reliability of the connection between the base and the cylinder, the base and the cylinder are prevented from being separated; can connect the inslot to set up spacing tooth soon, when protruding screw in connects the inslot soon gradually, spacing tooth can produce certain blocking effect to the arch, and the staff can continue rotatory barrel with strength, makes the arch cross spacing tooth to with protruding restriction in spacing tooth and connect the terminal space in groove soon, thereby can prevent effectively that the arch from screwing out and connect the groove soon, in order to promote the connection reliability between base member and the barrel.

In addition, in the implementation, the matching relationship and the specific structure between the first signal terminal, the second signal terminal and the conductive terminal may also be varied.

For example, the first signal terminal may include a metal dome disposed on the periphery of the substrate, the second signal terminal may include a metal dome disposed on the periphery of the substrate, and the first signal terminal and the second signal terminal may be disposed on the same circumference of the substrate at intervals; the conductive end may include a metal ring disposed within the barrel. After the barrel body is screwed with the base body and the protrusion is screwed into the space between the limiting tooth and the tail end of the screwing groove, the conductive end is electrically connected with the first signal end and the second signal end, namely the conductive end is short-circuited with the first signal end and the second signal end.

In a specific implementation, the first signal terminal and the second signal terminal may be disposed on the outer peripheral surface of the base body, may be disposed at the front end of the base body, or may be disposed at other positions.

In addition, because the barrel connects with the base member soon, can produce relative rotation between barrel and the second cable, in order to facilitate the relative rotation between realization barrel and the second cable, can also effectively guarantee the leakproofness between barrel and the second cable simultaneously, can adopt mobilizable connected mode between barrel and the second cable, for example, connect during the slip.

For example, in one embodiment provided herein, the second flashing assembly further comprises a back cover and a gasket. Particularly, the rear end of the barrel is provided with a plurality of elastic clamping jaws which can elastically deform in the radial direction of the barrel, the sealing ring is sleeved on the periphery of the second cable, the inner wall of the sealing ring is attached to the periphery of the second cable (a certain gap can be formed, and the sealing ring can also be tightly attached to the periphery of the second cable), and the outer wall of the sealing ring is attached to the inner wall of the rear end of the barrel. The barrel and the rear cover are connected in a threaded manner; specifically, the cylinder body is provided with external threads, and the rear cover is internally provided with internal threads and a pushing surface; after the internal thread of the rear cover is in threaded connection with the external thread of the cylinder body, the pushing face pushes the elastic clamping jaws to enable the elastic clamping jaws to contract towards the second cable and extrude the sealing ring so as to realize the airtight connection among the cylinder body, the sealing ring and the second cable and prevent water vapor from entering the cylinder body; in addition, the connection stability among the cylinder, the sealing ring and the second cable can be improved, and the relative displacement is prevented from being generated under the action of external force.

In specific implementation, the pushing surface may be a cambered surface structure or an inclined surface structure. For example, in an embodiment provided by the present application, because the connection manner of threaded connection is adopted between the barrel and the rear cover, that is, when the barrel is connected with the rear cover, there is relative rotation between the barrel and the rear cover, therefore, in order to ensure that the pushing surface can stably and efficiently push the elastic jaws to contract, the pushing surface is of a closed annular structure, so that when the barrel and the rear cover rotate relatively, the pushing surface can stably push the elastic jaws.

In addition, in some embodiments, the connection mode between the cylinder and the rear cover is not limited to a threaded connection, and may also adopt a connection mode such as an insertion connection, a clamping connection, and the like, which is not specifically limited in this application example.

In addition, in order to facilitate detection of the on-off conditions of the first signal end and the second signal end, in some embodiments, a detection circuit may be further disposed in the connection assembly; specifically, the detection circuit may be connected to the first signal terminal and the second signal terminal, and when the first signal terminal and the second signal terminal are in a disconnected state, the detection circuit may generate a corresponding detection signal; when the first signal terminal and the second signal terminal are connected through the conductive terminal, the detection circuit generates a corresponding detection signal.

On the other hand, this application embodiment still provides a camera, including the main part of making a video recording and the coupling assembling of above-mentioned arbitrary, the camera main part can be connected with outside cable through foretell coupling assembling to guarantee the leakproofness of junction, simultaneously, can also install in place by the initiative monitoring coupling assembling (first waterproof component and second waterproof component).

As shown in fig. 2, the present application provides an embodiment in which the connection assembly 10 includes a first terminal 11 and a second terminal 12; the first terminal 11 is located at one end of the first cable 001, the second terminal 12 is located at one end of the second cable 002, and the first cable 001 and the second cable 002 are electrically and hermetically connected through the first terminal 11 and the second terminal 12.

Specifically, as shown in fig. 3, the first terminal 11 may include: the first waterproof component comprises a first connecting end 111 and a first waterproof component 112 wrapped on the periphery of the first connecting end 111. The second terminal 12 may include: a second connecting end 121 and a second waterproof assembly 122 wrapped around the second connecting end 121. The first connecting end 111 and the second connecting end 121 are detachably connected; the first waterproof component 112 and the second waterproof component 122 are detachably connected in a sealing manner; the first connecting end 111 and the second connecting end 121 can be electrically connected with each other to achieve electrical connection between the first cable 001 and the second cable 002, and the first waterproof assembly 112 and the second waterproof assembly 122 can be connected with each other to achieve airtight connection between the first cable 001 and the second cable 002, so that waterproof performance of the first connecting end 111 and the second connecting end 121 is effectively guaranteed. Wherein the first waterproof member 112 includes a first signal terminal 1121 and a second signal terminal 1122 electrically connected to the first cable 001, and the second waterproof member 122 includes a conductive terminal (not shown); after the first waterproof component 112 and the second waterproof component 122 are hermetically connected, the conductive end is short-circuited with the first signal end 1121 and the second signal end 1122; by detecting the on-off condition of the first signal end 1121 and the second signal end 1122 (whether the first signal end 1121 and the second signal end 1122 are short-circuited by the conductive end), it can be known whether the first waterproof assembly 112 and the second waterproof assembly 122 are correctly installed in place, and whether the tightness between the first connection end 111 and the second connection end 121 is effectively guaranteed.

In practical implementation, the connection mode between the first connection end 111 and the second connection end 121 may be various.

For example, the first connection end 111 and the second connection end 121 may be connected in a plug-in connection manner. Specifically, the first connection end 111 may be an interface (e.g., an RJ45 interface), and the second connection end 121 may be a connector (e.g., an RJ45 connector, commonly referred to as a crystal connector), and the electrical connection between the first terminal 11 and the second terminal 12 can be realized by inserting the connector into the interface.

In some embodiments, the first connection end 111 may also be a joint, and the second connection end 121 may also be an interface.

In addition, in some embodiments, other types of interfaces may be used between the first connection end 111 and the second connection end 121, a rotational connection (such as a threaded connection) may also be used, or other connection methods may also be used, which is not specifically limited in this application.

In particular implementations, the connection between the first waterproof assembly 112 and the second waterproof assembly 122 may be various. For example, the first waterproof assembly 112 and the second waterproof assembly 122 may be connected in a rotatable manner.

Specifically, as shown in fig. 4, the first waterproof assembly 112 may include a substrate 1123 wrapping the periphery of the first connection end 111, and a first abutting surface 1124 is disposed on the periphery of the substrate 1123; the first connection end 111 may be located in the front end surface (right end surface) of the base body 1123 to facilitate connection with the second connection end 121. The second waterproof assembly 122 may include a cylinder 1222, and a rear end of the cylinder 1222 is sleeved on the periphery of the second cable 002 and is hermetically fitted with the periphery of the second cable 002; the front end of the cylinder 1222 is provided with a second abutting surface 1223 for airtight abutting with the first abutting surface 1124. After the base 1123 and the cylinder 1222 are screwed and fixed, the first butt-joint surface 1124 and the second butt-joint surface 1223 are hermetically combined, so that the hermetic butt-joint between the first cable 001 and the second cable 002 is realized.

Referring to fig. 5, in order to achieve the rotational connection between the base 1123 and the cylinder 1222, in one embodiment provided by the present application, the base 1123 is provided with a screwing groove 1125 (which may be an external thread structure), the inner wall of the cylinder 1222 is provided with a protrusion 1224 (which may be an internal thread structure) capable of screwing into the screwing groove 1125, and the first abutting surface 1124 and the second abutting surface 1223 can be tightly abutted after the protrusion 1224 is completely screwed into the screwing groove 1125.

As shown in fig. 4, in some embodiments, to increase the tightness between the first mating surface 1124 and the second mating surface 1223, a sealing ring 13 may be disposed between the first mating surface 1124 and the second mating surface 1223; specifically, the first abutting surface 1124 may be in sealing engagement with the left side of the sealing ring 13, and the second abutting surface 1223 may be in sealing engagement with the right side of the sealing ring 13, thereby achieving a sealing engagement between the first abutting surface 1124 and the second abutting surface 1223.

In some embodiments, to improve the reliability of the connection between substrate 1123 and barrel 1222, retaining teeth 1126 may be provided in depending groove 1125, such that when projection 1224 is gradually rotated into depending groove 1125, retaining teeth 1126 may provide some resistance to projection 1224, and the practitioner may continue to rotate barrel 1222 with force to force projection 1224 past retaining teeth 1126 to limit projection 1224 to the space between retaining teeth 1126 and the end of depending groove 1125, thereby effectively preventing projection 1224 from rotating out of depending groove 1125 to improve the reliability of the connection between substrate 1123 and barrel 1222, as shown in fig. 5.

In particular implementations, to facilitate the projection 1224 to clear the spacing teeth 1126 during threading of the projection 1224 into the threading slot 1125, the leading end surfaces of the spacing teeth 1126 may be beveled; in addition, after the projection 1224 passes over the limit teeth 1126, in order to prevent the projection 1224 from reversely rotating out of the screw-in groove 1125, the rear end surface of the limit teeth 1126 may have a straight structure so as to be able to provide a good stop for the projection 1224.

In addition, in practical implementation, the matching relationship and specific structure between the first signal terminal 1121, the second signal terminal 1122 and the conductive terminal 1221 can also be varied.

For example, in an embodiment provided by the present application, please refer to fig. 4 and fig. 5 in combination, the first signal end 1121 includes a metal spring piece disposed on the periphery of the substrate 1123, the second signal end 1122 includes a metal spring piece disposed on the periphery of the substrate 1123, and the first signal end 1121 and the second signal end 1122 are disposed on the same circumference of the substrate 1123 at intervals; conductive end 1221 comprises a metal ring disposed within barrel 1222. After the barrel 1222 is screwed to the base 1123 and the protrusion 1224 is screwed into the space between the limiting teeth 1126 and the end of the screwing groove 1125, the conductive end 1221 is electrically connected to the first signal end 1121 and the second signal end 1122, i.e., the conductive end 1221 short-circuits the first signal end 1121 and the second signal end 1122.

In practical implementation, the first signal end 1121 and the second signal end 1122 may be disposed on the outer peripheral surface of the base 1123, or may be disposed at the front end (right end surface) of the base 1123, or other positions, and those skilled in the art can adaptively adjust the positions of the first signal end 1121 and the second signal end 1122 according to actual needs, which is not specifically limited in this application.

In addition, when the cylinder 1222 is screwed with the base 1123, the cylinder 1222 and the second cable 002 rotate relatively, so that the cylinder 1222 and the second cable 002 rotate relatively, and the tightness between the cylinder 1222 and the second cable 002 can be effectively ensured.

As shown in fig. 4, in one embodiment provided herein, second flashing assembly 122 may include a rear cap 1225 and a gasket 14. Particularly, the rear end of barrel 1222 can set up a plurality of elasticity jack catchs 1226, and a plurality of elasticity jack catchs 1226 can be at the radial elastic deformation of barrel 1222, and the sealing washer 14 cover is established in the periphery of second cable 002, and its inner wall is laminated (can have certain clearance, also can closely laminate) with the periphery of second cable 002, and the inner wall laminating of its outer wall and barrel 1222 rear end. The barrel 1222 and the rear cover 1225 are connected by a thread; specifically, the cylinder 1222 is provided with external threads, and the rear cover 1225 is internally provided with internal threads and a pushing surface 1227; after the internal thread of the rear cover 1225 is screwed with the external thread of the cylinder 1222, the pushing surface 1227 pushes the elastic claws 1226, so that the elastic claws 1226 contract towards the second cable 002 and press the sealing ring 14, thereby realizing the airtight connection among the cylinder 1222, the sealing ring 14 and the second cable 002 and preventing water vapor from entering the cylinder 1222; in addition, the connection stability between the cylinder 1222, the seal ring 14 and the second cable 002 can be improved, and the relative displacement caused by the external force can be prevented.

In specific implementation, the pushing surface 1227 may be a cambered surface structure or an inclined surface structure; in an embodiment provided by the present application, since the cylinder 1222 and the rear cover 1225 are connected by a threaded connection, that is, when the cylinder 1222 and the rear cover 1225 are connected, there is a relative rotation between the cylinder 1222 and the rear cover 1225, so as to ensure that the abutting surface 1227 can smoothly and efficiently push the elastic claw 1226 to contract, the abutting surface 1227 is a closed annular structure, so that when the cylinder 1222 and the rear cover 1225 rotate relatively, the abutting surface 1227 can smoothly abut against the elastic claw 1226.

In addition, in some embodiments, the connection between the barrel 1222 and the rear cover 1225 is not limited to a threaded connection, and a connection manner such as a plug connection, a snap connection, etc. may also be used, which is not specifically limited in this embodiment.

In addition, in order to facilitate detecting the on/off of the first signal terminal 1121 and the second signal terminal 1122, in some embodiments, a detection circuit 15 may be further disposed in the connection assembly 10; specifically, the detection circuit 15 may be connected to the first signal terminal 1121 and the second signal terminal 1122, and when the first signal terminal 1121 and the second signal terminal 1122 are in an off state, the detection circuit 15 generates a corresponding off detection signal; when the first signal terminal 1121 and the second signal terminal 1122 are connected through the conductive terminal 1221, the detection circuit 15 generates a corresponding connection detection signal.

In specific implementation, the specific arrangement of the detection circuit 15 may be various. For example, as shown in fig. 6, in an embodiment provided by the present application, the detection circuit 15 may include an optical coupler (short for optocoupler), a plurality of diodes, and a resistor, where an input end (left end) of the optocoupler is provided with a first power supply circuit, and an output end (right end) of the optocoupler is provided with a second power supply circuit; the first signal end and the second signal end are arranged in the first power supply circuit in series and used for controlling the power-on and power-off states of the input end of the optical coupler; the second power supply circuit is provided with an output end, and the output end is connected with the optocoupler in parallel. Specifically, the left side K1 and the left side K2 represent the first signal terminal 1121 and the second signal terminal 1122, respectively, and when the first signal terminal 1121 and the second signal terminal 1122 are in the off state, the optical coupler does not work (it can be understood that the output terminal of the optical coupler is in the off state), and at this time, the voltage of the output terminal (represented by CPU in the figure) is equal to the voltage of the power supply V2. When the first signal end 1121 and the second signal end 1122 are in a closed state, the optical coupler operates (it can also be understood that the output end of the optical coupler is in a closed state), at this time, the output end is short-circuited due to the closing of the optical coupler, and the voltage to ground (GND2) is almost zero, so that after the first signal end 1121 and the second signal end 1122 are changed from an open state to a closed state, the voltage value of the output end (represented by a CPU in the figure) is obviously changed (reduced). The related device (e.g., a processor) in the electronic device can determine the open/close state of the first signal end 1121 and the second signal end 1122 according to the electrical signal (e.g., voltage value) at the output end, so as to determine whether the first waterproof assembly 112 and the second waterproof assembly 122 are installed in place.

In practical applications, the detection circuit 15 is not limited to the type shown in the embodiment of the present application, and a person skilled in the art may select the adaptive detection circuit 15 according to practical requirements, which is not specifically limited in this application.

In addition, in order to facilitate remote monitoring of the on/off states of the first signal terminal 1121 and the second signal terminal 1122, the detection circuit 15 may be further connected to the electronic device through the first cable 001.

As shown in fig. 7, the camera 20 provided by the present application includes an imaging main body 21 and the connection assembly 10 of any one of the above; the end of the first cable 001 not provided with the first terminal 11 is connected to the imaging main body 21.

In specific implementation, the camera body 21 may include electrical components such as a processor, the detection circuit 15 may be electrically connected to the processor, and the processor may detect the on/off status of the first signal end 1121 and the second signal end 1122 through the detection circuit 15, so as to determine whether the first waterproof assembly 112 and the second waterproof assembly 122 are installed in place, so as to achieve the purpose of remote detection and monitoring.
