Description

Video camera

Technical Field

The present invention relates to a camera mounting technique, and more particularly to a camera mounted on a wall and connected by an internal plug wire.

Background

The wall-mounted camera is connected with the signal of an external cable in a wiring mode of an internal plug wire, namely, the external cable is led into the camera and is plugged with a cable plugging interface in the camera.

Accordingly, the camera may comprise a camera body with a built-in movement, and a lead frame for mounting the camera body on a wall, wherein the cable plug interface is typically arranged at the camera body where the movement is located, the lead frame is arranged with a waterproof grommet plug in sealing engagement with an external cable, and the lead frame is in butt engagement with the camera body for applying waterproof protection to the cable plug interface.

Since the weight of the camera body accommodating the movement is large, it is often necessary to suspend the camera body at a position relatively far from the wall at the time of mounting operation. Therefore, after the wiring end of the external cable penetrates through the waterproof structure of the lead frame, the wiring end of the cable needs to be pulled to the camera body far away from the wall, and the wiring end of the external cable can be plugged with the cable plugging interface; after the camera body and the lead frame are assembled in a butt joint mode, the whole camera is installed on the wall. In addition, the redundant outgoing line part of the external cable which is pulled out for plugging with the cable plugging interface needs to be pulled back and recovered after the whole camera is installed on the wall.

It can be seen that for a video camera using wall-mounted and patch cord connections, pulling and retracting the external cables can result in cumbersome installation operations, and the sealing engagement between the external cables and the waterproof structure can be easily broken.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.

Fig. 1a and 1b are schematic exploded views of a camera according to an embodiment of the present invention. Fig. 2 is a schematic view of an assembly structure of the adapter plate of the camera shown in fig. 1 in the camera body. Fig. 3 is a schematic view of the mounting structure of the interface board of the camera shown in fig. 1 in the lead frame. Fig. 4 is a sectional view showing an assembled structure of the camera shown in fig. 1. Fig. 5 is a schematic view of the assembly principle of the camera shown in fig. 1. Referring to fig. 1a and 1b and fig. 2 to 5, the camera in this embodiment may include a camera body 10 and a lead frame 50.

The camera body 10 is provided with an adapter plate 20 on the side of the camera body that is in contact with the lead frame 50, and the adapter plate 20 has a first inter-board insertion interface 21 that is connected to the signal of the movement in the camera body 10 (the first inter-board insertion interface 21 can be welded to the adapter plate 20). The signal connection between the adapter plate 20 and the movement in the camera body 10 may include transmission connection of various signals such as network signals, power signals, audio signals, video signals, and alarm signals.

In this embodiment, taking the case that the camera body 10 includes the housing assembly 100 as an example, the housing assembly 100 may have a movement cavity case 100a for accommodating the movement, a flange cover 100b attached to an outer periphery of an opening of the movement cavity case 100a, and a docking barrel case 100c attached to an outer periphery of the flange cover 100b, that is, the docking barrel case 100c forms a docking side of the camera body 10 and the lead chassis 50.

Accordingly, the adapter plate 20 may be installed in the docking barrel cavity formed by the docking barrel housing 100c and connected to the movement signal in the movement cavity housing 100 a.

For example, please particularly pay attention to fig. 3, the adapter plate 20 may further have a cable connector 22 in signal connection with the first inter-board plug interface 21, the movement may be in signal connection with the cable connector 22 through an internal cable 41 (network signals, power signals, audio signals, video signals, alarm signals, and other signals), the camera body 10 further has a top case 12 (e.g., integrally formed with the case assembly 100) covering the movement at a side (the docking barrel case 100 c) docked with the terminal base 50, the adapter plate 20 may be mounted on the top case 12, and the top case 12 may be mounted with a wire cover 13 for the internal cable 41 to pass through.

The lead frame 50 is provided with an interface board 60 and a waterproof cord 500c for inserting the external cable 49, on the side of the interface with the camera main body 10, and the interface board 60 has a second board-to-board plug interface 61 (the second board plug interface 61 can be welded to the interface board 60) complementary to the first board-to-board plug interface 21, and a cable plug interface 62 facing the waterproof cord 500c (plug interfaces for various signals such as a network signal, a power signal, an audio signal, a video signal, and an alarm signal).

In this embodiment, taking the lead frame 50 including the housing assembly 500 as an example, the housing assembly 500 has a housing main body 500a forming a wire-hiding cavity therein, a waterproof wire holder 500b formed on the housing main body 500a, and a waterproof wire-passing plug 500c mounted on the waterproof wire holder 500 b.

For example, with particular attention to fig. 4, the housing body 500a may have a flat housing base plate, and the housing base body 500a may have a peripheral wall at the periphery of the housing base plate, the peripheral wall and the waterproof wire holder 500b together surrounding a wire-hiding cavity forming the housing base body 500a, at least one waterproof threading plug 500c mounted to the waterproof wire holder 500b may communicate with the wire-hiding cavity, and the interface board 60 may be disposed in the wire-hiding cavity and disposed such that the cable plugging port 62 faces the waterproof threading plug 500c mounted to the waterproof wire holder 500 b.

In addition, the first inter-board plug interface 21 is complementary to the second inter-board plug interface 61, and either one of the first inter-board plug interface 21 and the second inter-board plug interface 61 may be a male socket, and the other one may be a female socket.

With particular attention to fig. 5, after the external cable 49 is inserted into the lead frame 50 (wire hiding cavity) from the waterproof plug 500c and is plugged into the cable plugging interface 62 of the interface board 60, the first inter-board plugging interface 21 is plugged into the second inter-board plugging interface 61 by the butt-joint assembly of the camera body 10 and the lead frame 50, so as to form signal connection of various signals such as network signals, power signals, audio signals, video signals, alarm signals, and the like.

Based on the above structure, the interface board 60 having the cable plugging interface 62 and the waterproof threading plug 500c are both disposed on the lead frame 50, so as to allow the external cable 49 to be plugged into the cable plugging interface 62 without being pulled by a large force after passing through the waterproof threading plug 500c.

Furthermore, the adapter board 20 connected to the signal of the movement is provided on the camera body 10, and the adapter board 20 and the interface board 60 have the complementary first inter-board plug interface 21 and second inter-board plug interface 61, respectively, so that the first inter-board plug interface 21 can be plugged into the second inter-board plug interface 61 only by the plug-in fitting of the camera body 10 to the lead frame 50, thereby realizing the signal connection (various signals such as network signal, power signal, audio signal, video signal, alarm signal, etc.) between the external cable 49 and the movement.

In addition, referring back to fig. 1a and 1b, the camera in this embodiment may further include a mounting plate 80 for mounting the lead frame 50 on a wall.

For example, in actual installation:

s1: the lead frame 50 with smaller weight can be lifted to a position close to the installation position of the wall;

s2: the external cable 49 is inserted into the wire hiding cavity of the lead frame 50 from the waterproof threading plug 500c and is inserted into the cable plugging interface 62, wherein, as long as the lead frame 50 is close enough to the wall installation position when the external cable 49 is inserted, the pulling of the external cable 49 is reduced or even avoided;

s3: fixing the lead frame 50 in which the external cables 49 are inserted at the wall mounting position through the mounting plate 80, wherein if the external cables 49 penetrate into the lead frame 50 without being pulled or slightly pulled, the external cables 49 are pulled back to a very small extent at the moment, and even the external cables 49 are not pulled back;

s4: butting the camera main body 10 with a lead frame 50 fixed at a wall mounting position until the first inter-board plug interface 21 is plugged into the second inter-board plug interface 61;

s5: the camera body 10 is assembled to the docked lead mount 50 using the docking assembly screws 40.

Thus, the above structure helps to reduce or even avoid pulling and pulling back of the external cable 49 during the installation of the camera, and thus can reduce the troublesome degree of the installation operation of the camera and reduce or even avoid the damage to the sealing fit between the external cable 49 and the waterproof cord passing plug 500c.

Fig. 6 is a schematic diagram of the wiring provided by the lead frame of the camera of fig. 1 for the external cables. Referring to fig. 6, the external cable 49 may be a buried cable 49a with a main body part hidden in the wall, or an external cable 49b independent from the wall, and accordingly:

the waterproof threading plug 500c (waterproof wire holder 500 b) may be obliquely recessed inwardly from one side of the lead frame 50 (holder case main body 500 a) to form a lead space at the side of the lead frame 50 (holder case main body 500 a);

the mounting tray 80 may have a wire passing hole 800 for the passage of the buried wall cable 49a, the wire passing hole 800 communicating with the wire lead space in the axial direction of the wire lead housing 50 (the housing main body 500 a);

the terminal block 50 (block case main body 500 a) may further have a pipe clamp 52 for abutting against a protection pipe enclosing the external wall cable 49b on a side edge of the waterproof grommet 500c (waterproof wire holder 500 b) inclined recess, the pipe clamp 52 communicating with the lead space in a radial direction of the terminal block 50 (block case main body 500 a).

Accordingly, the docking cartridge housing 100c of the camera body 10 may be further formed with a tube socket opening 14 for complementary engagement with the tube clamp socket 52.

That is, the video camera of the wall-mounted and the patch cord type in the above embodiment can be compatible with patch cord connection between the wall-embedded cable 49a and the wall external cable 49 b.

In addition, in order to facilitate the installation operation, the video camera in the above embodiment has further structural optimization, which will be described in detail below.

(1) The structure optimization of the plug-in coarse guide between the plug-in interface 21 between the first boards and the plug-in interface 61 between the second boards is realized:

referring back to fig. 1a and 1b and fig. 5, the camera body 10 (the docking cradle 100 c) may further have a first mounting and positioning mechanism 11, and the lead frame 50 (the cradle body 500 a) may further have a second mounting and positioning mechanism 51 complementary to the first mounting and positioning mechanism 11, for example, one of the first mounting and positioning mechanism 11 and the second mounting and positioning mechanism 51 may be a positioning boss (the first mounting and positioning mechanism 11 is taken as an example of the positioning boss in the drawing), and the other one may be a positioning recess complementary to the boss in shape (the second mounting and positioning mechanism 51 is taken as an example of the positioning recess in the drawing);

moreover, the complementary fit between the first assembly positioning mechanism 11 and the second assembly positioning mechanism 51 may generate a positioning guide for the assembly between the camera body 10 and the lead frame 50, for example, the positioning boss and the positioning groove may adopt an inclined surface fit, so that the insertion positioning between the first inter-board insertion interface 21 and the second inter-board insertion interface 61 may be guided by the assembly guide between the camera body 10 and the lead frame 50.

(2) The structure optimization of the accurate direction of inserting between the inserting interface 21 between the first plates and the inserting interface 61 between the second plates is realized:

fig. 7 is a schematic diagram of the fine positioning guide of the adapter plate and the interface plate of the camera shown in fig. 1. Referring to fig. 7 and back to fig. 2 and 3, in the optimized structure, the camera may further include a first inner cover 30 and a second inner cover 70.

The first inner decorative cover 30 has an opening exposing the first inter-board inserting connection port 21, and the first inner decorative cover 30 is further provided with a first inserting positioning flange 31 disposed on the periphery of the opening exposing the first inter-board inserting connection port 21.

Moreover, the second inner decorative cover 70 has an opening exposing the second inter-board inserting connection port 61, and a second inserting positioning flange 71 complementary to the first inserting positioning flange 31 is disposed on the periphery of the opening exposing the second inter-board inserting connection port 61 of the second inner decorative cover 70.

By assembling the camera main body 10 and the lead frame 50, a positioning guide for guiding the first inter-board plug interface 21 to be plugged into the second inter-board plug interface 61 is generated between the first plug positioning flange 31 and the second plug positioning flange 71.

For example, the first and second plug-in positioning flanges 31 and 71 may each have complementary wedge surfaces for forming a plug-in guide. In the illustration, since the insertion design in which the second insertion positioning flange 71 is inserted into the first insertion positioning flange 31 is adopted, the inner periphery of the first insertion positioning flange 31 has a wedge surface, and the outer periphery of the second insertion positioning flange 71 has a wedge surface that is inclined complementarily to the first insertion positioning flange 31, for example, but in the actual design, if the insertion design in which the first insertion positioning flange 31 is inserted into the second insertion positioning flange 71 is adopted, the outer periphery of the first insertion positioning flange 31 may have a wedge surface, and the inner periphery of the second insertion positioning flange 71 may have a wedge surface that is complementary to the first insertion positioning flange 31.

And, the above-mentioned complementary wedge surfaces can realize the clearance positioning fit through positioning the convex rib 79, in order to realize the high-accuracy direction. In the drawings, taking the positioning rib 79 as an example to form the second wedge surface on the outer periphery of the second plug positioning flange 71, the positioning rib 79 can form a small clearance fit of, for example, 0.1mm with the first wedge surface, and thus, by the discrete small clearance fit at the plurality of positioning ribs 79, a higher guiding accuracy than a simple surface contact can be formed. It will be understood that the positioning ribs 79 may be arranged on the wedge surfaces of the first plug-in positioning flanges 31 instead, or on the wedge surfaces of the first plug-in positioning flanges 31 and the second plug-in positioning flanges 71 which are complementary to each other.

In addition, to achieve high-precision positioning:

the first interior cover 30 and the adapter plate 20 are mounted on the camera main body 10 (the case top 12) by the same positioning reference (the positioning column 121), for example, the adapter plate positioning hole 200 of the adapter plate 20 is in positioning fit with the positioning column 121 disposed on the camera main body 10 (the case top 12) and is fixed to the camera main body 10 (the case top 12) by the adapter plate fixing screw 122, and the interior cover positioning hole 300 of the first interior cover 30 is also in positioning fit with the positioning column 121 disposed on the camera main body 10 (the case top 12);

the interface board 60 can be positioned and assembled to the second inner cover 70, and thus can be assembled to the lead frame 50 (the housing main body 500 a) with the second inner cover 70 as a positioning reference (the assembling screw 600 and the positioning pin 720), for example, the assembling screw 600 can be fixed to the mounting hole 710 of the second inner cover 70 through the screw hole 610 of the interface board 60, so as to assemble the interface board 60 and the second inner cover 70 into a whole; the positioning pin 720 of the second inner decoration cover 70 can be inserted into the positioning pin hole 620 of the interface board 60 to realize the positioning fit of the interface board 60 and the second inner decoration cover 70; also, the interface board 60 and the second inner cover 70, which are positioned, fitted and assembled as a single body, can be mounted on the lead frame 50 (the housing main body 500 a) by the inner cover mounting screws 700.

Based on the above structure, the first inter-board inserting connection port 21 and the first inserting connection positioning flange 31 use the same positioning reference (the positioning column 121 of the camera main body 10), and the second inter-board inserting connection port 61 and the second inserting connection positioning flange 71 use the same positioning reference (the second inner decorative cover 70), so that there is no cascading accumulation of tolerance between the first inserting connection positioning flange 31 and the first inter-board inserting connection port 21, and between the second inserting connection positioning flange 71 and the second inter-board inserting connection port 61, and thus, by the cooperation of the first inserting connection positioning flange 31 and the second inserting connection positioning flange 71, the inserting direction between the first inter-board inserting connection port 21 and the second inter-board inserting connection port 61 can be more accurately realized.

In addition, the first inner cover 30 may further have a first cap covering the cable holder 22 and the inner cable 41, and the second inner cover 70 may further have a second cap covering the cable plugging interface 62.

(3) The structure optimization for pre-hanging and holding the camera main body 10 and the lead frame 50 after the insertion interface 21 between the first board and the insertion interface 61 between the second board is as follows:

fig. 8 is a schematic diagram illustrating the assembly of the patch panel and the interface board of the camera shown in fig. 1. Referring to fig. 8 and referring back to fig. 2 and 3, in this configuration, the first inner cover 30 may further have a first pre-hanging mechanism 32, and the second inner cover 70 may further have a second pre-hanging mechanism 72, wherein when the first board-to-board plug interface 21 is plugged into the second board-to-board plug interface 61, the first pre-hanging mechanism 32 is snap-fitted with the second pre-hanging mechanism 72, for example, the first pre-hanging mechanism 32 and the second pre-hanging mechanism 72 may be buckles with which snap protrusions are oppositely arranged, so that a retaining force for retaining the camera body 10 at the current relative position with the lead frame 50 can be generated.

Structural optimization based on pre-hang keeping:

firstly, during the period of utilizing the screws to realize the assembling connection of the camera main body 10 and the butted lead frame 50, the additional lifting of the camera main body 10 can be avoided, and the installation operation is further simplified;

secondly, the insertion state between the first inter-board insertion interface 21 and the second inter-board insertion interface 61 can be stabilized by the retention force generated by the clamping and matching of the first pre-hanging mechanism 32 and the second pre-hanging mechanism 72, so that the relative shaking between the first inter-board insertion interface 21 and the second inter-board insertion interface 61 caused by screwing the screws can be avoided during the period of utilizing the screws to realize the assembly and connection of the camera main body 10 and the butted lead frame 50, and the virtual insertion or strong torsion damage caused by the relative shaking between the first inter-board insertion interface 21 and the second inter-board insertion interface 61 can be avoided;

furthermore, the snap-fit of the first pre-hanging mechanism 32 and the second pre-hanging mechanism 72 can generate a hand feedback in response to the successful insertion of the first inter-board insertion interface 21 and the second inter-board insertion interface 61, which is helpful for an installer to accurately determine whether the camera main body 10 and the lead frame 50 are in place.

(4) And the structure optimization for controlling the effective plugging depth between the first inter-board plugging interface 21 and the second inter-board plugging interface 61 is as follows:

since the fitting accuracy of the first inter-board plug interface 21 and the second inter-board plug interface 61 in the plug depth depends on the assembly tolerance between the interface board 20 and the camera body 10, the assembly tolerance between the adapter board 60 and the lead frame 50, and the assembly tolerance between the camera body 10 and the lead frame 50, the optimized structure scheme aims to compensate the influence of the superposition of multiple stages of assembly tolerances on the plug depth of the first inter-board plug interface 21 and the second inter-board plug interface 61, for example, the deviation of the actual plug depth of the first inter-board plug interface 21 and the second inter-board plug interface 61 from the preset plug depth (expected plug depth) is controlled to be not more than 0.5mm.

Fig. 9 is a schematic diagram of the docking compensation constraint of the patch panel and the interface board of the camera shown in fig. 1. Referring to fig. 9, in the preferred embodiment, the adapter plate 20 is fixedly mounted in the camera body 10 (fixedly mounted on the housing top 12), and the interface plate 60 is mounted in the lead frame 50 by using the elastic suspension mechanism 90. When the first inter-board plugging interface 21 and the second inter-board plugging interface 61 are plugged and mated, the elastic suspension mechanism 90 supports the interface board 60 in a suspension manner to form an over-plugging trend exceeding a preset plugging depth between the first inter-board plugging interface 21 and the second inter-board plugging interface 61, and the elastic suspension mechanism 90 absorbs a portion of the plugging and mating depth (actual plugging and mating depth) exceeding the preset plugging depth through elastic deformation.

For example, the elastic suspension mechanism 90 may include an elastic element 91 and a limit screw 92, when the interface board 60 is mounted on the lead frame 50 by the elastic suspension mechanism 90, the elastic element 91 may elastically support the interface board 60 in the plugging direction of the first inter-board plugging interface 21 and the second inter-board plugging interface 61, and the interface board 60 is limited by the limit screw 92 at a position (board distance H _ int between the interface board 60 and the adaptor board 20) where the first inter-board plugging interface 21 and the second inter-board plugging interface 61 form an over-plugging trend, and the elastic element 91 is pressed to form an elastic pre-stress.

The position of the interface board 60 supported by the elastic element 91 and limited by the limiting screw 92 (the board distance H _ int between the interface board 60 and the adapter board 20) may be considered as an over-insertion matching error produced by human engineering, and at this time, when the first inter-board insertion interface 21 and the second inter-board insertion interface 61 are in insertion matching, the actual insertion depth between the two will not reach the degree of over-insertion, so that the interface board 60 supported by the elastic element 91 is pressed to retreat to the position of the appropriate actual insertion depth (the board distance H _ exp between the interface board 60 and the adapter board 20), thereby realizing the absorption compensation of the portion of the elastic suspension mechanism 90 where the insertion matching depth (the actual insertion matching depth) exceeds the preset insertion depth.

Based on the above structure, the elastic suspension mechanism 90 may constrain the plugging fit depth between the first inter-board plugging interface 21 and the second inter-board plugging interface 61 towards the preset plugging depth.

It should be understood that the elastic suspension mechanism 90 may be disposed between the adapter plate 20 and the camera main body 10 instead, that is, the adapter plate 20 is mounted on the camera main body 10 (the case top 12) by the elastic suspension mechanism 90, and the interface board 60 is fixedly mounted in the lead frame 50, and at this time, the elastic suspension mechanism 90 can still produce substantially the same effect.

For example, when the adaptor board 20 is mounted on the camera main body 10 by the elastic suspension mechanism 90, the elastic element 91 elastically supports the adaptor board 20 in the insertion direction of the first board-to-board insertion interface 21 and the second board-to-board insertion interface 61, the adaptor board 20 is limited by the limiting screw 92 at a position where the insertion tendency between the first board-to-board insertion interface 21 and the second board-to-board insertion interface 61 is formed, and the elastic element 91 is pressed to form an elastic prestress.

Similarly, the adaptor plate 20 is supported by the elastic element 91 and is limited by the limit screw 92, so as to form the above-mentioned artificially manufactured over-inserted matching error, at this time, when the first inter-plate plug connector 21 is plug-in matched with the second inter-plate plug connector 61, the actual plug depth between the two will not reach the over-inserted degree, so that the adaptor plate 20 supported by the elastic element 91 is extruded to retreat to the position of the proper actual plug depth, and thus the absorption compensation of the elastic suspension mechanism 90 on the part of the plug-in matching depth (actual plug-in matching depth) exceeding the preset plug depth can also be realized.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
