Description

Technical Field

[0001] This utility model relates to the field of signal generator technology, specifically a signal generator for power distribution network reliability testing. Background Technology

[0002] Utility model patent with publication number CN220752204U discloses a test signal generator, including a test signal generator body, a baffle, a fixing block, a rotating rod, a torsion spring, and a positioning structure. The operating end of the test signal generator body is equipped with a baffle for blocking the operating end of the test signal generator body. A fixing block is symmetrically fixedly installed on the top of one end of the test signal generator body corresponding to the baffle. A rotating rod is rotatably installed between the fixing block and the baffle. A torsion spring is sleeved on one end of the rotating rod. One end of the torsion spring is fixedly connected to the end of the rotating rod away from the baffle, and the other end of the torsion spring is fixedly connected to one side of the fixing block. A positioning structure for fixing the position of the baffle is fixedly installed between the test signal generator body and the baffle. When the test signal generator is not in use, the torsion spring drives a baffle to rotate around the central axis of the rotating rod, blocking the operating end of the test signal generator to prevent dust adhesion. When the test signal generator is in use, the baffle can also be used to block the operating end, preventing accidental button presses. Furthermore, the positioning structure allows for easy removal of the baffle from its obstructed position. A sealing gasket is fixedly installed at the operating end of the test signal generator corresponding to the position of the baffle. When the baffle blocks the operating end, the sealing effect of the operating end is improved by the contact between the sealing gasket and the baffle.

[0003] The above-mentioned patents have the following shortcomings:

[0004] When the signal generator is not in use, the baffle can cover the screen and interface of the signal generator to prevent dust from accumulating on them. However, when the signal generator is in use, a connecting cable needs to be used to connect to the signal generator's interface. There is no locking mechanism between the interface and the connector of the connecting cable. Due to movement of the signal generator or the connection, the connection between the connector of the connecting cable and the interface of the signal generator may become loose. Utility Model Content

[0005] In view of the problems existing in a power distribution network reliability test signal generator, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a power distribution network reliability test signal generator, which solves the problem in the aforementioned patent where, when the signal generator is not in use, a baffle can be used to cover the screen and interface of the signal generator, thereby preventing dust from accumulating on the screen and interface. However, when the signal generator is in use, a connecting cable needs to be used to connect to the signal generator's interface. There is no locking structure between the interface and the connector of the connecting cable. Due to movement of the signal generator or the connection, the connection between the connector of the connecting cable and the interface of the signal generator may become loose.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

Figure 1-7 It includes a signal generator body 1, a shield 4 is hinged to the signal generator body 1 via a hinge 7, the signal generator body 1 has an interface 6, and the signal generator body 1 is provided with a locking structure, which can prevent the data cable connected to the interface 6 from separating from the interface 6.

[0028] The signal generator body 1 has a screen 3, and a shield 4 can cover the screen 3 and the interface 6.

[0029] Support legs 2 are provided at both ends of the bottom of the signal generator body 1. A sealing ring 5 is glued to the inner wall of the shield 4. When the shield 4 is rotated to cover the signal generator body 1, the sealing ring 5 will tighten around the end of the signal generator body 1, thereby shielding the screen 3 and the interface 6 and preventing dust from falling on the screen 3 and the interface 6.

The second mounting plate 122 is connected to a U-shaped support frame 11 by bolts.

[0031] In practical use, when the signal generator body 1 is not in use, the shield 4 is rotated and placed on the end of the signal generator body 1. The sealing ring 5 will be tightly fitted on the end of the signal generator body 1, thereby shielding the screen 3 and the interface 6 and preventing dust from falling on the screen 3 and the interface 6.

[0032] When using the signal generator body 1, flip the shield 4 upward to expose the interface 6 and screen 3 of the signal generator body 1, press down the U-shaped locking block 10, connect the connector 141 of the connecting cable 14 to the interface 6, release the U-shaped locking block 10, and under the elastic force of the spring 12, the U-shaped locking block 10 will fit between the connecting cable 14 and the connector 141, thereby preventing the connector 141 from moving out of the interface and ensuring the reliability of the connection between the connector 141 and the interface 6.
