DETAILED DESCRIPTION

[0037] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0038] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0039] The utility model provides a test fixture 1000 for testing a shunt 2000. The structure of the shunt 2000 is as follows: Figures 1 to 3 As shown, it includes a shunt body 80 , a current contact 81 is provided on the upper side of the shunt body 80 , and a connector 82 is also provided. The connector 82 is used to connect to a transversely inserted test plug to read the voltage of the shunt 2000 .

[0040] The existing test fixture 1000 can only press the probe down to the contact on the upper side of the diverter 2000. For the sample to be tested with the connector 82, the test plug can usually only be manually plugged in. On the one hand, the operation is inconvenient and the efficiency is low when testing multiple samples. On the other hand, manual operation cannot ensure that the plugging position and plugging force are consistent each time, which can easily lead to measurement errors due to manual operation.

[0041] To solve the above technical problems, please refer to Figures 4 to 7 The utility model provides a test fixture 1000 for testing a shunt 2000 having a connector 82. The test fixture 1000 includes a base 10, a vertical test mechanism 200, and a horizontal test mechanism 300. The base 10 is composed of a base plate 11 and a vertical plate 12. A bearing member 13 is provided on the base plate 11 for fixing the shunt 2000. There is no restriction on the structural material, as long as the shunt 2000 can be firmly supported and fixed. For example, an open groove for accommodating the shunt 2000 can be opened on the upper side of the support member, and the shape of the open groove is transplanted with the outer contour of the shunt 2000.

[0042] Furthermore, the vertical test mechanism 200 is arranged on the vertical plate 12, and includes a vertical driving member 201 and a vertical probe 202. The vertical driving member 201 drives the vertical probe 202 to move up and down, so that the vertical probe 202 contacts and conducts the diverter body 80 during the downward movement. The horizontal test mechanism 300 is arranged on the bottom plate 11, and includes a horizontal driving member 301 and a horizontal probe 302. The horizontal driving member 301 drives the horizontal probe 302 to move in the front-back direction, so that the horizontal probe 302 is plugged into and conducts the connector 82 during the forward movement.

[0043] When the test fixture 1000 provided in this embodiment is used to test the shunt 2000, it is only necessary to operate the vertical drive member 201 to press the vertical probe 202 down to contact the probe, and operate the horizontal drive member 301 to drive the horizontal probe 302 forward to plug the connector 82. It should be noted that the specific structure of the vertical drive member 201 and the horizontal drive member 301 is not limited, and the power source can be electric or manual. Using the test fixture 1000 provided in this embodiment to test the shunt 2000 not only makes the test operation more convenient and improves the test efficiency, but also ensures the repeatability of the plug-in effect of the connector 82, and reduces the measurement error caused by manually plugging the test plug.

[0044] Based on the previous embodiment, please continue to refer to Figures 4 to 7 The vertical driving member 201 further includes a first connecting rod assembly 20, a first handle 30 and a first top plate 40. The first connecting rod assembly 20 is arranged on the vertical plate 12, and has a first driving end and a first linkage end. The first handle 30 is arranged at the first driving end to have a movable stroke for rotating relative to the vertical plate 12. The vertical probe 202 is provided on the lower side of the first top plate 40. The first top plate 40 is arranged at the first linkage end so that the first handle 30 drives the vertical probe 202 to move upward during the movable stroke of rotating upward, and drives the vertical probe 202 to move downward during the movable stroke of rotating downward. This structure provides a stable and reliable driving method for the vertical probe 202, is easy to operate, and has accurate alignment, so that users can perform tests more conveniently.

[0045] Further, the first connecting rod assembly 20 includes a first bracket 21, a first curved rod 22 and a first swing rod 23.

The first curved rod 22 is bent and has a first bending portion 221 and two first rod portions 222 arranged on both sides of the first bending portion 221, one of the first rod portions 222 constitutes the first driving end and is sleeved with the first handle 30, and the end of the other first rod portion 222 is rotatably connected to the first bracket 21, one end of the first swing rod 23 is rotatably connected to the first bending portion 221, and the other end is rotatably connected to the first push rod 24, and the first push rod 24 is inserted into the first guide sleeve 211. The distal end of the first push rod 24 constitutes the first linkage end and is provided with a first top plate 40.

[0046] In this embodiment, when the user operates the first handle 30 to rotate upward, the first handle 30 drives the first curved rod 22 to rotate upward, drives the first swing rod 23 to swing accordingly, and then drives the first push rod 24 to move upward along the first guide sleeve 211, and finally drives the first top plate 40 and the vertical probe 202 installed on the upper part to move upward and away from the diverter 2000. Conversely, when the user operates the first handle 30 to rotate downward, the first handle 30 drives the first curved rod 22 to rotate downward, drives the first swing rod 23 to swing accordingly, and then drives the first push rod 24 to move downward along the first guide sleeve 211, and finally drives the first top plate 40 and the vertical probe 202 installed on the upper part to move downward until they press and touch the current contact 81.

[0047] On the basis of the above-mentioned embodiment, the vertical probe 202 is detachably arranged on the first top plate 40, and preferably, the position of the vertical probe 202 is adjustable in the horizontal plane in front of the first top plate 40. In this way, a suitable vertical probe 202 can be selected for contact according to the model and size of the diverter 2000, and the position of the vertical probe 202 can be adjusted accordingly.

[0048] Further, according to different test requirements, the vertical probes 202 can be provided with two or four.
