[0002] On the junction box production line, newly manufactured junction boxes must be inspected to test their quality and ensure compliance. Traditionally, this inspection method relies on manual testing, where a test plug is inserted into each plug under test at a time, resulting in inefficient testing. During the inspection process, the test plug is inserted manually, and the insertion force and depth are inconsistent, which can easily lead to insufficient contact between the test plug and the plug under test, resulting in inaccurate test results. Furthermore, improper or misaligned insertion of the plug under test into the test plug can damage the junction box panel. This not only affects the aesthetics of the junction box, but also its sealing and durability.

[0003] Therefore, in order to solve the above problems, a detection device for a junction box is proposed. Utility Model Content

[0012] Furthermore, thirteen through holes are arranged vertically along the base on the upper surface of the mounting plate, and the mounting plate is sleeved on the outer side walls of the thirteen test plugs through the thirteen through holes.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-2 In this embodiment, a detection device for a junction box is used, in which multiple groups of detection pins 32 are connected through a PCB board 31. With the cooperation of the propulsion cylinder 2, the multiple groups of detection pins 32 are inserted into the plugs to be tested 51 on the junction box 5, so as to realize a single detection of all the plugs to be tested 51 on the junction box 5, thereby improving the detection efficiency. Moreover, under the push of the propulsion cylinder 2, the multiple groups of detection pins 32 enter the plugs to be tested 51 to the same depth, making the detection operation more standardized and the detection results more accurate. With the cooperation of the limit rod 41 and the limit block 4, the detection pins 32 can correspond to the plugs to be tested 51 more accurately, thereby improving the detection efficiency and further improving the accuracy of the detection.

[0026] Specifically, a detection device for a junction box 5 in this embodiment includes a base 1 and a detection component 3;

[0027] A frame 11 is mounted on one side of the upper surface of the base 1, and a propulsion cylinder 2 is mounted on the bottom of the top plate of the frame 11;

[0028] The output shaft of the propulsion cylinder 2 is arranged vertically downward and a receiving plate 21 is installed at the bottom;

[0029] Two support columns 22 are installed on the bottom of the receiving plate 21 along the two lateral edges of the base 1;

[0030] The detection assembly 3 is mounted at the bottom of the two support columns 22. The detection assembly 3 includes a PCB board 31 mounted at the bottom of the two support columns 22. Thirteen groups of detection pins 32 are arranged at the bottom of the PCB board 31.

[0031] Two limit blocks 4 are installed on the upper surface of the base 1 at intervals along the horizontal direction of the base 1. A junction box 5 is clamped between the two limit blocks 4. Thirteen groups of test plugs 51 are arranged on the upper end of the junction box 5.

[0032] The thirteen groups of detection pins 32 correspond to the thirteen groups of plugs to be tested 51 respectively.

[0033] During actual use, the user places the junction box 5 to be tested between the two limit blocks 4, and then controls the propulsion cylinder 2 to operate. The propulsion cylinder 2 runs its output shaft to push the PCB board 31 downward, so that the thirteen groups of detection pins 32 can be respectively inserted into the thirteen groups of plugs to be tested 51, thereby realizing a single test of all the plugs to be tested 51 on the junction box 5, which improves the detection efficiency. Moreover, the thirteen groups of detection pins 32 are pushed by the propulsion cylinder 2 to the same depth of entering the plugs to be tested 51, making the detection operation more standardized and the detection results more accurate.

[0034] A test plug 33 is sleeved on the outer wall of each group of detection pins 32 , and a mounting plate 34 is sleeved on the outer side wall of the test plug 33 .

[0035] Thirteen through holes are formed on the upper surface of the mounting plate 34 in a vertical arrangement along the base 1 . The mounting plate 34 is sleeved on the outer side walls of the thirteen test plugs 33 through the thirteen through holes.

[0036] Positioning holes 35 are formed downwardly through the upper surface of the mounting plate 34 along opposite sides of the base 1 .

[0037] Limiting rods 41 are installed on the upper surfaces of the two limiting blocks 4. The two limiting rods 41 pass through the mounting plate 34 through the two positioning holes 35 respectively. The mounting plate 34 is slidably connected to the limiting rods 41.

[0038] Under the cooperative constraints of the mounting plate 34 and the limiting rod 41, when the propulsion cylinder 2 pushes the detection pin 32 downward, the test plug 33 and the detection pin 32 will not be displaced in the horizontal direction, thereby avoiding the misalignment of the detection pin 32 and the plug to be tested 51.

[0039] A cable plug 36 is mounted on the output end of the PCB board 31 .

[0040] During actual use, by plugging the cable plug 36 into the multi-function tester, each set of detection pins 32 can be connected to the multi-function tester, avoiding the traditional detection method in which the cable of each detection plug needs to be connected to the tester when the detection plug is connected to the tester. This method is inefficient and prone to errors.

[0041] The two limiting blocks 4 are provided with limiting grooves 42 on their opposite surfaces.

[0042] The upper surface of the junction box 5 is respectively fitted with the inner top walls of the two limiting grooves 42 at the two opposite transverse edges of the base 1 .

[0043] Under the restriction of the limit groove 42 , after the detection is completed, when the output shaft of the propulsion cylinder 2 retracts upward, the junction box 5 is prevented from moving upward with the detection pin 32 due to the connection between the detection pin 32 and the plug to be tested 51 .

[0044] The working principle of the above embodiment is:

[0045] The user places the junction box 5 to be tested between the two limit blocks 4, so that the edges of the upper surface of the junction box 5 are respectively in contact with the top walls of the two limit grooves 42; then the propulsion cylinder 2 is controlled to operate, and the propulsion cylinder 2 operates its output shaft to push the PCB board 31 downward, so that the thirteen groups of detection pins 32 can be respectively inserted into the thirteen groups of plugs to be tested 51, and then the cable plug 36 is plugged into the multi-function tester. In this way, all the plugs to be tested 51 on the junction box 5 can be tested at a time, which improves the detection efficiency. Moreover, the thirteen groups of detection pins 32 are pushed by the propulsion cylinder 2 to the same depth of entering the plugs to be tested 51, making the detection operation more standardized and the detection results more accurate.

[0046] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
