Description

Technical Field

[0001] The utility model relates to a broadcast audio jumper test device, belonging to the technical field of broadcast audio jumper equipment. Background Technique

[0002] Broadcasting refers to a news dissemination tool that transmits sounds through radio waves or wires. An audio jumper is a small switch that controls the current flow on a circuit board. Its function is to adjust the on-off relationship of different electrical signals on the device and thereby adjust the working state of the device, such as determining the main board voltage, the master-slave relationship of the drive, etc. The audio jumper needs to be tested with a special tester, and the interfaces of most existing testers are directly exposed.

[0003] Publication No.: CN219087141U mentions a broadcast audio jumper test device. By setting a protective shell and a cover plate, the wiring port can be protected to reduce dust from entering the wiring port and affecting the test of the jumper. By setting a spring, the cover plate can automatically rebound and close after being opened. At the same time, by setting a dial block, it is easier to open the cover plate to facilitate inserting the jumper into the wiring port for testing, greatly increasing the accuracy of the jumper tested by the device. However, the device can only shield the wiring port from dust. When some jumpers are inserted into the wiring port, they are relatively loose and prone to poor contact. The device cannot assist in strengthening the jumpers inserted into the wiring port, thereby affecting the subsequent test effect of the jumpers. Now there is an urgent need for a broadcast audio jumper test device to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a broadcast audio jumper test device to solve the problems raised in the above background technique. The utility model designs a spring clip type dust-proof structure, which can perform dust-proof treatment on the exposed wiring port and can also clamp and limit the jumper when it is inserted into the wiring port, making the jumper inserted into the wiring port more firmly, so that there will be no poor contact phenomenon.

[0005] To achieve the above object, the utility model is realized by the following technical solutions: A broadcast audio jumper test device, comprising a test instrument, a U-shaped dust-proof plug board, a jumper, and a pull-down board. An insertion port is installed at the right end of the test instrument, and a fixed base is horizontally fixed at the lower end of the insertion port. A first small compression spring and a second small compression spring are respectively longitudinally installed at the front and rear sides of the lower end of the fixed base. First sliding slots and second sliding slots are respectively penetrated and opened at the upper right side of the fixed base. The U-shaped dust-proof plug board is respectively slidably inserted between the first sliding slot and the second sliding slot. A first clamping groove is opened at the left side of the upper end of the U-shaped dust-proof plug board, and a second clamping groove is opened at the right side of the upper end of the U-shaped dust-proof plug board. A pull-down board is horizontally fixed at the lower right side of the right end of the U-shaped dust-proof plug board by epoxy resin glue. The jumper is inserted into the insertion port.

[0006] Further, anti-slip support blocks are installed around the lower end of the test instrument, and a plurality of heat dissipation slots are opened at the front and rear ends of the test instrument.

[0007] Further, the first small compression spring and the second small compression spring are respectively fixed to the front and rear sides of the lower end inside the U-shaped dust-proof plug board.

[0008] Further, both the first small compression spring and the second small compression spring are in a stretched state.

[0009] Further, the lower end of the jumper is tightly clamped between the first clamping groove and the second clamping groove.

[0010] Further, a test indicator light is installed at the front end of the test instrument.

[0018] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a wiring harness test device for a broadcast audio jumper, including a test instrument 1, a U-shaped dust-proof plug board 6, a jumper 12 and a pull-down plate 11. A wiring port 2 is installed at the right end of the test instrument 1, a fixed base 3 is horizontally fixed at the lower end of the wiring port 2, a first small compression spring 9 and a second small compression spring 10 are respectively longitudinally installed at the front and rear sides of the lower end of the fixed base 3, a first sliding slot 4 and a second sliding slot 5 are respectively penetrated and opened at the upper right side of the fixed base 3, the U-shaped dust-proof plug board 6 is respectively slidably inserted between the first sliding slot 4 and the second sliding slot 5, a first clamping groove 7 is opened at the upper left side of the upper end of the U-shaped dust-proof plug board 6, a second clamping groove 8 is opened at the upper right side of the upper end of the U-shaped dust-proof plug board 6, a pull-down plate 11 is horizontally fixed at the lower right side of the right end of the U-shaped dust-proof plug board 6 through epoxy resin glue, and the jumper 12 is inserted into the wiring port 2. This design solves the problem that the original device can only block and dust-proof the wiring port. When some jumpers are inserted into the wiring port, they are relatively loose and prone to poor contact. The device cannot assist in strengthening the jumpers inserted into the wiring port, thereby affecting the subsequent test effect of the jumpers.

[0019] As the first embodiment of the present utility model: anti-slip support blocks 13 are installed around the lower end of the test instrument 1, and a plurality of heat dissipation slots are opened at the front and rear ends of the test instrument 1. By adding the anti-slip support blocks 13, it is convenient to support the test instrument 1, and the opening of a plurality of heat dissipation slots facilitates the heat dissipation of the internal components of the test instrument 1.

[0020] The first small compression spring 9 and the second small compression spring 10 are respectively fixed to the front and rear sides of the lower end inside the U-shaped dust-proof plug board 6. By adding that the first small compression spring 9 and the second small compression spring 10 are respectively fixed to the front and rear sides of the lower end inside the U-shaped dust-proof plug board 6, it can further prevent the U-shaped dust-proof plug board 6 from detaching between the first sliding slot 4 and the second sliding slot 5. The first small compression spring 9 and the second small compression spring 10 are both in a stretched state. By adding that the first small compression spring 9 and the second small compression spring 10 are both in a stretched state, it can further make the first small compression spring 9 and the second small compression spring 10 rebound upward, so that the jumper wire 12 is stably clamped between the first clamping groove 7 and the second clamping groove 8.

[0021] The lower end of the jumper wire 12 is tightly clamped between the first clamping groove 7 and the second clamping groove 8. By adding that the lower end of the jumper wire 12 is tightly clamped between the first clamping groove 7 and the second clamping groove 8, it can ensure the stability of the jumper wire 12 installed at the wiring port 2 and prevent subsequent poor contact. The front end of the test instrument 1 is equipped with a test indicator light. By adding that the test indicator light is connected to the test instrument 1 through a wire, it can be used for subsequent tests respectively. And the circuits and electronic components involved in the test instrument 1 are all prior arts and can be fully realized by those skilled in the art without further elaboration.

[0022] As the second embodiment of the present utility model: When the wiring port 2 is not in use, the U-shaped dust-proof plug board 6 is in the initial dust-proof state (refer to Figure 2 ), and when it is necessary to use the jumper wire 12 for testing, push down the pull-down plate 11, and the U-shaped dust-proof plug board 6 can be driven to move downward in the first sliding slot 4 and the second sliding slot 5. During this process, the first small compression spring 9 and the second small compression spring 10 are driven to stretch downward, and the wiring port 2 will also be exposed. Until the wiring port 2 is completely exposed, insert the jumper wire 12 into the wiring port 2, and then release the pull-down plate 11. The first small compression spring 9 and the second small compression spring 10 will reset upward, driving the U-shaped dust-proof plug board 6 to move upward in the first sliding slot 4 and the second sliding slot 5 until the lower end of the jumper wire 12 is tightly clamped between the first clamping groove 7 and the second clamping groove 8 (refer to Figure 1 ), which can prevent the jumper wire 12 from easily falling off and causing poor contact.
