Description

Technical Field

[0001] The invention relates to the technical field of detection devices, and in particular to a compact and practical terminal block clamp for a wall-mounted controller. Background Art

[0002] After the wall-mounted controller is assembled, it is necessary to carry out necessary testing of the whole machine. However, the cabinet of the wall-mounted controller is relatively small, and the control signals, indication signals, communication interfaces, input signals, etc. output to the outside are all sealed inside the cabinet. If there is no small card-connecting fixture to lead out the signal, the signal to be tested can only be led to the whole machine test fixture for automatic testing through manual wiring. After the test is completed, these wirings must be removed, which is particularly troublesome to operate and affects the test efficiency.

[0003] The existing direct plug-in clamp uses the elastic stroke of the test probe to insert one end of the probe into the terminal block wiring hole, compress the probe, and push the other end of the clamp to the shell of the wall-mounted controller to achieve the clamping connection. However, the test pin of this type of direct plug-in clamp is subject to stress and is easily damaged. Since the stroke of the test pin is limited, the space available for operation during alignment is also limited, which is very inconvenient to operate.

[0004] The wall-mounted controller includes a rectangular cabinet, in which a terminal row with terminal openings facing upward is arranged. Summary of the invention

[0005] The purpose of the present invention is to provide a compact and practical wall-mounted controller terminal block clamp to solve the problems mentioned in the above background technology that the test pins of the direct plug-in clamp are easily damaged due to stress, and the operating space is limited during alignment, making operation inconvenient.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a compact and practical terminal block clamp for wall-mounted controllers, applied to wall-mounted controllers, comprising a test pin plate which is horizontally placed above the terminal block to be tested when in use, a first pinhole group consisting of a plurality of first pinholes whose numbers and positions correspond to the terminals on the terminal block to be tested and are used to install test probes is provided on the upper surface of the test pin plate, a flip block which can be flipped upward is rotatably provided on the upper surface of the test pin plate near the front side of the first pinhole group, after the test probe is inserted into the terminal block, its elastic stroke is compressed to the maximum and the flip block is flipped upward to be perpendicular to the upper surface of the test pin plate, the movable end of the flip block is pressed against the inner top wall of the cabinet of the wall-mounted controller.

[0007] Furthermore, it also includes a limit block arranged on the upper surface of the test needle plate, and the limit block is used to prevent the flip block from continuing to flip backward after flipping to be perpendicular to the upper surface of the test needle plate, so as to prevent the limit block from pressing the test probe.

[0008] Furthermore, the limit block is arranged above the first pinhole group, and a second pinhole group is provided on the upper surface of the limit block. The second pinhole group includes a plurality of second pinholes for the test probe to be inserted into the first pinhole, so as to facilitate the installation of the test probe while playing a limiting role.

[0009] Furthermore, a first limiting surface is provided on the front side of the limiting block, and a second limiting surface is provided on the upper surface of the flip block. When the flip block flips to be perpendicular to the upper surface of the test needle plate, the first limiting surface and the second limiting surface abut against each other.

[0010] Furthermore, the outer side surface of the flip block is arranged in an arc shape to facilitate snap connection.

[0011] Furthermore, two flip blocks are symmetrically arranged on the test needle plate, and a connecting block is connected between the two flip blocks. The symmetrical arrangement of the two flip blocks is convenient for improving the stability of the structure. The connecting block facilitates the simultaneous movement of the two flip blocks to prevent the test needle plate from being affected by stress due to uneven force on the left and right sides.

[0012] Furthermore, the movable end of the flip block is made of Teflon material to prevent scratches on the inner top wall of the controller.

[0013] The beneficial effects of the present invention are: the present invention has a simple structure and is easy to use. By arranging a flip block that can be flipped upward on the test needle plate, when starting the test, the test needle plate is pressed downward after the test probe is installed. When the elastic stroke of the test probe is the largest, the flip block is flipped to be perpendicular to the test needle plate, and the movable end of the flip block can abut against the inner top wall of the controller, so that the test probe and the terminal row to be tested are kept vertically pressed to avoid the test probe being affected by stress. After the test is completed, the test needle plate is compressed downward, and the test needle plate is loosened after the flip block is turned downward, which is convenient for removing the clamp. In addition, by arranging the flip block at the front side of the first pinhole group, it remains horizontal due to gravity when not flipped, and will not block the installation of the test probe, leaving a larger operating space for the tester, which is convenient for operation.
