Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, and in particular to a filter testing device. Background Technology

[0002] Before leaving the factory, filters need to undergo signal transmission testing. Currently, to test filters, interference fit connectors are used to connect the filter's terminals to the test cables, thus completing the test. A filter often has multiple terminals. In the past, the terminals were often placed on the same side and arranged in a row. During testing, all test cables were brought into contact with the filter's terminals from the same direction to achieve a conductive connection, thus initiating the test.

[0003] Chinese patent CN221446133U discloses a rapid clamping test device for producing filters, comprising a fixed base, a guide assembly mounted on the fixed base, a sliding pressure plate sleeved on the guide assembly and sliding circumferentially along the guide assembly, a clamping assembly mounted on the sliding pressure plate, several test components mounted on the clamping assembly for testing, and a locking assembly. The clamping assembly ensures that the sliding pressure plate always tends to move away from the test components. The locking assembly has at least one state in which the sliding pressure plate pushes the clamping assembly to press the test components firmly onto the filter to be tested. Here, the guide assembly consists of a fixed post and a guide rail bushing. The sliding pressure plate is connected to the guide rail bushing, and multiple test adapters are arranged on the sliding pressure plate, each equipped with a spring. Therefore, the test adapters contact the insertion holes through the lifting and lowering movement of the sliding pressure plate, and the springs apply pressure to prevent the test adapters from loosening.

[0004] However, some filters have connection terminals on both sides. Although theoretically, a row of adapters can be plugged into the connection terminals on both sides using sliding pressure plates, one end is always difficult to separate due to the greater clamping force, which leads to a longer preparation time.

[0005] Therefore, a dedicated testing device needs to be designed to solve the above problems. Utility Model Content

[0006] The main purpose of this invention is to provide a filter testing device that can efficiently and reliably complete the conductive connection for filters with connection ends on both sides, ensuring that the test preparation work can be completed quickly.

[0007] The present invention achieves the above objectives through the following technical solution: a filter testing device, comprising a support platform, a lower detection component disposed at the lower part of the support platform, and an upper detection component disposed above the support platform; the filter comprises a flat box body, the front of the box body is provided with a row of upper connecting ends, the back of the box body is provided with a row of lower connecting ends, and the edge of the box body has multiple ears; The support platform is provided with a plurality of positioning posts that support and position the box body, and the positioning posts are matched with the ear. The lower detection assembly includes multiple lower adapters fixed side by side on the support platform, the upper end of the lower adapter protruding from the upper surface of the support platform and matching the height of the lower connection end; The upper wiring assembly includes a cable bracket and several cables passing side by side through the cable bracket. Each cable has an upper adapter at its end for connecting to the upper connection end. There is a sufficient height difference between the cable bracket and the upper surface of the support platform for the filter to be in place and removed.

[0008] Specifically, all the positioning posts form a detection area, and a pillow block is provided at the front of the support platform. A fork that extends into the detection area is placed on the pillow block.

[0009] Furthermore, the pillow block has a groove in the middle, and the shift fork includes a handle portion that matches the width of the groove and a fork portion located at the end of the handle portion, the fork portion being offset from the parts of the lower detection assembly.

[0010] Specifically, the top of the lower adapter has a multi-lobed elastic joint that matches the structure of the lower connecting end.

[0011] Specifically, the cable bracket includes two columns on the support platform, a fixing plate fixed to the upper end of the two columns, and a clamping plate connected to one side of the long side of the fixing plate. The fixing plate and the clamping plate are provided with arc-shaped notches on their opposite sides, and each pair of arc-shaped notches are joined together to form a circular hole for the cable to pass through.

[0012] The beneficial effects of this utility model's technical solution are: 1. In this testing device, the lower adapter can be plugged into all the lower connection ends at once, and the upper adapter is plugged into the upper connection ends one by one. This avoids the problem of poor reliability when too many connection ends are connected synchronously. The upper connection ends are aligned individually, which is highly efficient and suitable for filters with connection ends on both sides.

[0013] 2. The shift fork can use the pillow block as a fulcrum and leverage the lever principle to pry up the filter, which facilitates the separation of the lower connection end and the lower adapter and improves work efficiency.

[0014] 3. The adapters are inserted and removed one by one, so they will not interfere with each other and cause separation difficulties. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to specific embodiments.

[0018] Example: like Figure 1 and Figure 2 As shown, a filter testing device 100 of this utility model includes a support platform 1, a lower detection component 2 disposed at the lower part of the support platform 1, and an upper detection component 3 disposed above the support platform 1.

[0019] The filter 200 targeted by this device includes a flat housing 201. The front of the housing 201 has a row of upper connection terminals 202, and the back has a row of lower connection terminals 203. The edge of the housing 201 has multiple ears 204. The lower detection component 2 is responsible for connecting all the lower connection terminals 203, and the upper detection component 3 is responsible for connecting all the upper connection terminals 202, thereby completing the test preparation work.

[0020] like Figure 3 and Figure 6As shown, the support platform 1 is provided with a plurality of positioning posts 11 that support and position the box 201. The positioning posts 11 match the ear 204. All the positioning posts 11 form a detection area. The front part of the support platform 1 is provided with a pillow block 12. The middle part of the pillow block 12 is provided with a groove 121. A fork 4 that extends into the detection area is placed on the pillow block 12. The fork 4 includes a handle part 41 that matches the width of the groove 121 and a fork part 42 located at the end of the handle part 41. The fork part 42 is offset from the parts of the lower detection assembly 2.

[0021] Although the housing 201 is close to a cuboid structure, the upper connecting end 202 and the lower connecting end 203 protrude from the upper or lower surface of the housing 201, which prevents the housing 201 from lying flat naturally. Therefore, positioning posts 11 are needed to level it. After the filter 200 is in place, there is a gap between the housing 201 and the upper surface of the support platform 1. The fork 4 can slide along the groove 121, so that the forked structure of the fork 42 is between the adjacent lower adapters 21. In this way, the fork 4 can use the pillow block 12 as a fulcrum and use the lever principle to pry up the filter 200, which facilitates the separation of the lower connecting end 203 from the lower adapter 21 and improves work efficiency.

[0022] like Figure 2 and Figure 4 As shown, the lower detection component 2 includes multiple lower adapters 21 fixed side by side on the support platform 1. The upper end of the lower adapter 21 protrudes from the upper surface of the support platform 1 and matches the height of the lower connection end 203. The top of the lower adapter 21 has a multi-lobed elastic joint 211 that matches the structure of the lower connection end 203.

[0023] Because the heights of the lower adapter 21 and the lower connecting end 203 are limited by the positioning post 11 and the support platform 1, respectively, when placing the filter 200, the fixed multi-lobed elastic connector 211 must pass through the interior of the lower connecting end 203 to engage. The multi-lobed elastic connector 211 can use elastic deformation to pass through the narrowest diameter of the lower connecting end 203, and then generate a clamping force with the lower connecting end 203 by expanding outward. Therefore, the operator can clearly feel the vibration during engagement when placing the filter 200, thus ensuring that each lower adapter 21 is connected to the corresponding lower connecting end 203.

[0024] like Figure 5 As shown, the upper wiring assembly 3 includes a cable bracket 31 and several cables 32 passing side by side through the cable bracket 31. Each cable 32 has an upper adapter 33 at its end that connects to the upper connection end 202. There is a sufficient height difference between the cable bracket 31 and the upper surface of the support platform 1 for the filter 200 to be in place and removed.

[0025] Cable 32 is a component that can be bent at a certain curvature, allowing for flexible adjustment of the direction of the upper adapter 33 to align it with the corresponding upper connection end 202. The cable bracket 31 can support the weight of the cable 32; the operator only needs to hold the outer side of the upper adapter 33 for alignment, reducing workload and eliminating concerns about the cables tangled. The upper adapters 33 are inserted and removed one by one, without interfering with each other and causing separation difficulties.

[0026] like Figure 5 As shown, the cable bracket 31 includes two columns 311 mounted on the support platform 1, a fixing plate 312 fixed to the upper end of the two columns 311, and a clamping plate 313 connected to one side of the long side of the fixing plate 312. The fixing plate 312 and the clamping plate 313 are provided with arc-shaped notches on their opposite sides, and each pair of arc-shaped notches is joined together to form a circular hole for the cable 32 to pass through.

[0027] The cable bracket 31 allows the middle of the cable 32 to be suspended at a certain height from the support platform 1 (i.e., the height of the column 311) by the clamping of the fixing plate 312 and the clamping plate 313. This avoids the trouble of arranging different cables 32 and also makes the upper adapter 33 have a clear and intuitive arrangement. The range of motion of the hanging upper adapter 33 is only concentrated near the corresponding upper connection end 202, preventing incorrect connection to the upper connection end 202.

[0028] In this testing device, the lower adapter 21 can be plugged into all the lower connection ends 203 at once, and the upper adapter 33 is plugged into the upper connection ends 202 respectively. This avoids the problem of poor reliability when too many connection ends are connected synchronously. The upper connection end 202 has high alignment efficiency when aligned individually, and is suitable for filters 200 with connection ends on both sides.

[0029] The operating procedure for this filter testing device 100 is as follows: 1. Place the shift fork 4 on the pillow block 12 in advance, and make the fork part 42 located in the detection area.

[0030] 2. Move the filter 200 forward below the cable bracket 31. After ensuring that the lower connection end 203 corresponds one-to-one with the lower adapter 21, press the filter 200 down so that the lower connection end 203 engages with the multi-lobed elastic connector 211 and the ear 204 is supported by the positioning post 11.

[0031] 3. Manually adjust each upper adapter 33 so that it is inserted into the corresponding upper connection end 202 in sequence. After all connection ends are inserted, the test preparation work is completed.

[0032] 4. Power on the filter testing device 100 to complete the testing process, then power off.

[0033] 5. First, unplug all the upper adapters 33, use the fork 4 to pry up the box 201, so that all the lower connection ends 203 are disconnected from the corresponding multi-lobed elastic connectors 211, and then remove the tested filter 200.

[0034] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
