Technical Field

[0001] This utility model relates to the field of multi-channel signal source control devices, and in particular to a multi-channel signal source control device that is easy to wire. Background Technology

[0002] A multi-channel signal source control device is a system that can simultaneously manage, switch, and process multiple input / output signal channels. It is widely used in broadcasting and communication, industrial automation, medical equipment, testing and measurement, and other fields. It can control the signal source by connecting multiple signal transmission lines to the surface of the controller through the interface holes.

[0003] During use, due to the small size of the docking holes on the controller surface, when the external transmission line is connected to the docking hole, it is easy to encounter a situation where the connection cannot be made quickly due to docking deviation. This makes it impossible to quickly connect the wires on the controller surface. Furthermore, the controller needs to be inspected during use, at which time the transmission line needs to be unplugged. After the inspection is completed, it needs to be reconnected, which will once again put the staff into a situation of difficulty in docking, making it impossible to quickly put the controller into use. Utility Model Content

[0004] In view of the problem in the above or existing technology that when the external transmission line is connected to the surface of the controller, it is difficult to quickly connect due to the small size of the connection hole, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A guiding component includes a guiding plate, a support plate fixedly connected to the inner wall of the guiding plate, a controller for controlling a signal source at the front end of the guiding plate, a plurality of terminals fixedly connected to the surface of the controller, a sliding assembly for guiding transmission lines to make connections between the terminals and the guiding plate, and a limiting assembly for fixing the position of the guiding plate between the sliding assembly and the guiding plate; a fixing component includes a locking assembly disposed on the inner wall of the guiding plate, the locking assembly being used to lock and limit the tail end of the transmission line connector.

[0007] As a preferred embodiment of the multi-channel signal source control device of this utility model that facilitates wiring, the limiting component includes an insert plate fixedly connected to the surface of the slide plate, a limiting plate fixedly connected to the lower surface of the base plate, the insert plate being engaged with the limiting plate, and a pressure plate fixedly connected to the surface of the limiting plate.

[0008] As a preferred embodiment of the multi-channel signal source control device of this utility model that facilitates wiring, wherein: the inner arc of the support plate is adapted to the length of the transmission line, and the support plate is used to support the long position of the transmission line.

[0009] As a preferred embodiment of the multi-channel signal source control device of this utility model that facilitates wiring, wherein: a protrusion is fixedly connected to the inclined surface of the plug plate, a groove is provided on the inner wall of the limiting plate, the protrusion is made of rubber, and the protrusion is adapted to the groove.

[0010] As a preferred embodiment of the multi-channel signal source control device of this utility model that facilitates wiring, the locking assembly includes a driving block slidably connected to the surface of the guide plate. The surface of the driving block has teeth. Two round rods are rotatably connected to the surface of the guide plate. One end of each of the two round rods is fixedly connected to a gear.

[0011] As a preferred embodiment of the multi-channel signal source control device of this utility model that facilitates wiring, wherein: a torsion spring is sleeved on the surface of the round rod, and the two ends of the torsion spring are respectively fixedly connected to the guide plate and the gear, and the torsion spring is in the unfolded state in its normal state.

[0012] The advantages of this utility model's convenient wiring multi-channel signal source control device are:

[0013] 1. The guiding components, using a guide plate and support plate, allow for simple positioning and guidance of the transmission line connection, enabling quick alignment and precise connection with the wiring terminal, significantly improving the ease of connection. Furthermore, inserting a plug into the limiting plate locks the guide plate, firmly restricting the position of the connection terminal and effectively preventing it from falling outwards, thus ensuring the stability of signal transmission.

[0014] 2. By using the fixed components and the downward pressure generated when the connecting end is embedded in the guide plate, the driving block is driven to move downward.

Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Example 1, referring to Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a multi-channel signal source control device that facilitates wiring and enables quick wiring between the transmission line connection end and the terminal block. It includes a guiding component, including a guiding plate 10. A support plate 11 is fixedly connected to the inner wall of the guiding plate 10. A controller 12 for controlling the signal source is provided at the front end of the guiding plate 10. Several terminals 13 are fixedly connected to the surface of the controller 12. A sliding component 14 for guiding the transmission line to be wired is provided between the terminal block 13 and the guiding plate 10. A limiting component 15 for fixing the position of the guiding plate 10 is provided between the sliding component 14 and the guiding plate 10. The fixing component includes a locking component 20 provided on the inner wall of the guiding plate 10. The locking component 20 is used to lock and limit the tail end of the transmission line connector.

[0023] Specifically, when the transmission line is connected to the terminal 13, the guide plate 10 and the support plate 11 guide the transmission line, thereby helping the transmission line and the terminal 13 to be in a coaxial position. At this time, by sliding... The movable guide plate 10 can connect the transmission line to the terminal 13, while the limiting component 15 can limit the position of the guide plate 10 so that the transmission line will not loosen after the connection is made.

[0024] Furthermore, the sliding assembly 14 includes a base plate 141 fixedly connected to the surface of the controller 12, and a slide plate 142 fixedly connected to the arc surface of the guide plate 10. The slide plate 142 is U-shaped and slidably connected to the base plate 141. The limiting assembly 15 includes an insert plate 151 fixedly connected to the surface of the slide plate 142, and a limiting plate 152 fixedly connected to the lower surface of the base plate 141. The insert plate 151 and the limiting plate 152 are engaged, and a pressure plate 155 is fixedly connected to the surface of the limiting plate 152.

[0025] When the transmission line is inside the guide plate 10, it slides on the surface of the base plate 141 via the slide plate 142, which can drive the insertion plate 151 to slide towards the limiting plate 152. When the insertion plate 151 is inserted into the inner wall of the limiting plate 152, the transmission line is connected to the terminal 13. At this time, the transmission line completes the connection operation, and the staff does not need to spend time to perform coaxial docking between the transmission line and the terminal 13.

[0026] Preferably, the inner arc of the support plate 11 is adapted to the length of the transmission line, and the support plate 11 is used to support the long position of the transmission line. A protrusion 153 is fixedly connected to the inclined surface of the insertion plate 151, and a groove 154 is formed on the inner wall of the limiting plate 152. The protrusion 153 is made of rubber and is adapted to the groove 154.

[0027] It should be noted that the support plate 11 can support the long end of the transmission line, so that when the long end is pulled, the connection between the long end and the transmission line will not be damaged due to bending, which facilitates the wiring of the transmission line. After the plug plate 151 enters the inner wall of the limiting plate 152 for limiting, the protrusion 153 will simultaneously enter the groove 154. Furthermore, because the material of the protrusion 153 can further increase the friction, it increases the stability of the transmission line wiring connection and ensures that the signal will not change.

[0028] When in use, hold the connector of the transmission line in your hand, place it on the upper side of the guide plate 10, and position it in the middle along the two inclined surfaces of the guide plate 10. At this time, the connector of the transmission line and the terminal 13 are in a coaxial position, and the long line behind the transmission line will be supported by the support plate 11 and will not bend easily. At this time, the operator can push the support plate 11, so that the support plate 11 and the guide plate 10 slide on the surface of the base plate 141 under the effect of the sliding plate 142. When the connector of the transmission line and the terminal 13 are connected, the plug plate 151 will enter the interior of the limiting plate 152 to complete the locking and limiting. At the same time, the protrusion 153 will enter the interior of the groove 154. Because the protrusion 153 is made of rubber, the plug plate 151 will not detach from the interior of the limiting plate 152 when the pressure plate 155 is not pressed, ensuring the stability of the connection between the connector of the transmission line and the terminal 13, and preventing it from loosening or falling off during signal transmission.

[0029] Example 2, refer to Figures 1-4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a locking component 20 for a multi-channel signal source control device that facilitates wiring, based on embodiment 1. This solves the problem that the connection end of the transmission line will be flipped backward and detached from the guide plate 10 due to gravity when it is disconnected from the terminal 13. The locking component 20 includes a driving block 201 that is slidably connected to the surface of the guide plate 10. The surface of the driving block 201 has teeth. Two round rods 202 are rotatably connected to the surface of the guide plate 10. One end of each of the two round rods 202 is fixedly connected to a gear 203. The teeth of the gear 203 mesh with the teeth of the driving plate. An extension plate 205 is fixedly connected to the surface of the gear 203. An arc plate 206 is fixedly connected to the side of the extension plate 205 away from the gear 203.

[0030] Specifically, when the connection end of the transmission line is on the inner wall of the guide plate 10, pressure is applied to the drive plate, which in turn drives the gear 203 to rotate, so that the two arc plates 206 on both sides can move closer to each other, thereby clamping the tail end of the transmission line and preventing the transmission line from detaching from the surface of the guide plate 10 after it is disconnected from the terminal 13, making it convenient to reconnect.

[0031] Furthermore, a torsion spring 204 is fitted on the surface of the round rod 202. The two ends of the torsion spring 204 are fixedly connected to the guide plate 10 and the gear 203, respectively. The torsion spring 204 is normally in the unfolded state.

[0032] It should be noted that after the transmission line is separated from the surface of the guide plate 10, the torsion spring 204 will drive the arc plate 206 to reset its position, and it is not easy for it to rotate again, which facilitates the next installation of the transmission line and the limit operation.

[0033] During use, when the transmission line is connected to terminal 13, the connecting end is placed in the middle of the guide plate 10. During this placement, pressure is applied to the drive plate, causing it to slide down and engage with the teeth on its surface to rotate the gear 203. The gear 203 then rotates the extension plate 205 and the arc plate 206 towards the center. The arc plates 206 on both sides rotate towards each other, thus clamping the tail end of the transmission line connection. This prevents the transmission line connection from flipping backward due to the weight of the rear cable when it slides outward and disconnects from terminal 13, keeping the connection coaxial with terminal 13. When reconnection of terminal 13 is required... When connecting terminal 13, push the support plate 11 to slide towards terminal 13 again. When the transmission line needs to be replaced, the operator can press the pressure plate 155 to disengage the insertion plate 151 from the limit plate 152. At this time, the slide plate 142 can slide outward. When it slides to the extreme position, the operator can pull the transmission line outward from terminal 13 to disengage the connection end from the guide plate 10. At this time, the surface of the drive plate is freed from the pressure of the connection end. Furthermore, the gear 203 will be driven by the torsion spring 204 to slide the extension plate 205 and the arc plate 206 away from the center. At this time, the two arc plates 206 open, and the operator can take out the transmission line and replace it.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
