Description

Technical Field

[0001] This invention relates to the field of connector testing technology, and in particular to a test structure for connectors. Background Technology

[0002] With the booming development of the information appliance industry, people have increasingly higher requirements for the appearance and size of products. Product quality and performance testing can directly reflect the performance of a product, making product testing equipment particularly important for the information appliance industry. Connectors have the function of transmitting and exchanging signals between electronic terminals, and can directly connect product test signals from the product to testing equipment for testing. Therefore, the demand for connectors is also huge. Furthermore, because the information appliance industry updates and iterates rapidly, the need for short-term, small-batch production and market launch is also crucial. Product shapes are becoming increasingly complex, leading to increasingly unique connector structures. The production of connectors with unique shapes mostly relies on mold making, but mold making is time-consuming and expensive. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the aforementioned technical problems in the prior art. To this end, embodiments of the present invention provide a test structure for connectors, suitable for the functional testing needs of most testing industries, and eliminating the need for mold making. This effectively addresses a range of supply needs, including small-batch prototyping and mass production, significantly reducing finished product costs, saving the high costs of traditional molded connectors, shortening manufacturing time, and enabling rapid prototyping and manufacturing.

[0004] According to an embodiment of the present invention, a test structure for a connector includes two electrically connected test sections. Each test section includes a first fixing member, a second fixing member, a mating member, and a PCBA board. The second fixing member has a first connecting end and a second connecting end that are perpendicularly connected to each other. After the first fixing member is fixedly connected to the second connecting end, it defines a plurality of limiting grooves for limiting the range of motion of the mating member. One end of the mating member, which is engaged with the limiting groove, protrudes from the limiting groove, and the other end is connected to the PCBA board fixed to the first connecting end. The mating member includes two symmetrically arranged conductive clips. The portion of the conductive clips protruding from the limiting groove is provided with a pre-tightening structure so that the ends of the two conductive clips tend to approach each other. The first fixing member and the second connecting end also define a slot for the connecting part of the connector under test to engage, so that the pins of the connector under test can be inserted between the two conductive clips.

[0005] According to an embodiment of the present invention, in a test structure for a connector, the end of the conductive clip first extends obliquely to one side to form a first pre-tightening portion, and then extends obliquely to the other side to form a second pre-tightening portion. The first pre-tightening portion and the second pre-tightening portion constitute the pre-tightening structure. After the two conductive clips are positioned in the limiting groove, the pre-tightening structures of the two conductive clips abut against each other.

[0006] According to an embodiment of the present invention, in a test structure for a connector, the first fixing element array is arranged with a plurality of channels, the channels passing through both ends of the first fixing element, and the second connecting end covering the channels to form the limiting groove.

[0007] According to an embodiment of the present invention, a test structure for a connector includes a conductive clip comprising a first segment and a second segment connected to each other, a pre-tightening structure disposed on the second segment, the width of the first segment being smaller than the width of the second segment, and a channel comprising a first slot segment and a second slot segment, the width of the second slot segment being adapted to the width of the second segment, and the width of the first slot segment being adapted to the width of the first segment, so that the first slot segment and the second slot segment form a limiting step.

[0008] According to an embodiment of the present invention, in a test structure for a connector, two conductive clips are arranged vertically in the limiting groove, with a distance of 0.6 mm between the two conductive clips. The bottom of the second groove segment is 0.2 to 0.3 mm lower than the bottom of the first groove segment, and the second connecting end is recessed 0.2 to 0.3 mm below the position of the second groove segment.

[0009] According to an embodiment of the present invention, a test structure for a connector is provided with first notches symmetrically arranged on both sides of the first fixing member, and a second notch is provided at the position of the second connecting end corresponding to the first notch, the second notch covering the first notch to form the slot.

[0010] According to an embodiment of the present invention, a test structure for a connector is provided with a first groove at the end of the first fixing member away from the pre-tightening structure, and a second groove is provided at the position of the second connecting end corresponding to the first groove. The first groove and the second groove cooperate to position and define the PCBA board.

[0011] According to an embodiment of the present invention, in a test structure for a connector, the first connection end has a clearance groove machined on one side for fixing the PCBA board.

[0012] According to an embodiment of the present invention, a test structure for a connector is provided on the PCBA board at the position corresponding to the limiting groove, wherein a fixing hole is provided for positioning and fixing the mating member, and the mating member is electrically connected to the circuit on the PCBA board.

[0013] According to an embodiment of the present invention, in a test structure for a connector, two test sections are electrically connected by a flexible flat cable, the end of which is pressed and fixed to the first connection end by a pressure block, and the flexible flat cable is electrically connected to the circuit on the PCBA board.

[0014] Based on the above technical solution, the embodiments of the present invention have at least the following beneficial effects: In the above technical solution, the two conductive clips of the mating component are placed at the designated position of the first fixing component. After the second connecting end of the second fixing component is connected to the first fixing component, the range of motion of the conductive clips is restricted in the forming limiting groove. Then, the conductive clips are welded to the PCBA board at certain intervals to form an independent test section. The PCBA boards of the two test sections are electrically connected together so that connector testing can be performed. In view of the structural diversity of the connector products to be tested, this application ensures that the mating component can be adapted to the pin testing of most connector products by setting the limiting groove and controlling the gap between the two conductive clips. The setting of the pre-tightening structure This design ensures sufficient clamping force between the two conductive clips to press the pins of the connector under test firmly. Through a simple structural design, it eliminates the need for mold making. A single testing structure can meet the testing needs of different products, products with rapid updates and iterations, and products requiring clamping force. This significantly reduces high mold-making costs, shortens manufacturing time, and enables rapid testing and prototyping of connector products. Furthermore, the vertical connection between the first and second connecting ends of the second fixing member facilitates manual handling during testing, effectively saving space and resolving situations where there is insufficient space between the two connector products to be tested. The defined slots facilitate rapid positioning and docking of the connector under test, allowing the pins of the connector under test to be accurately inserted between the two conductive clips for rapid testing.

[0030] Reference Figure 1 and Figure 2The test structure for connectors in this application embodiment includes two electrically connected test sections. Each test section includes a first fixing member 100, a second fixing member 200, a mating member 400, and a PCBA board 500. The second fixing member 200 has a first connecting end 210 and a second connecting end 220 that are perpendicularly connected to each other. After the first fixing member 100 is fixedly connected to the second connecting end 220, it defines a plurality of limiting grooves 702 for restricting the range of motion of the mating member 400. One end of the mating member 400, which is engaged in the limiting groove 702, protrudes from the limiting groove 702 to allow the connector to be tested to be positioned within the limiting groove 702. The connector 800 is connected to the other end of the docking member 400, which is fixed to the PCBA board 500 of the first connecting end 210. The docking member 400 includes two symmetrically arranged conductive clips 410. The portion of the conductive clips 410 exposed in the limiting groove 702 is provided with a pre-tightening structure so that the ends of the two conductive clips 410 tend to approach each other. The first fixing member 100 and the second connecting end 220 also define a slot 701 for the connection part of the connector under test 800 to be engaged, so that the pins of the connector under test 800 can be inserted between the two conductive clips 410.

[0031] In this application, during the assembly of the connector test structure, two conductive clips 410 of the multiple mating components 400 are placed at designated positions on the first fixing component 100. After the second connecting end 220 of the second fixing component 200 is connected to the first fixing component 100, the resulting limiting groove 702 restricts the range of motion of the conductive clips 410. The conductive clips 410 are then soldered onto the PCBA board 500 to form an independent test section. The two conductive clips 410 are spaced apart by a certain distance, and the PCBA boards 500 of the two test sections are electrically connected together to enable connector testing. Given the structural diversity of the connector products to be tested, this application ensures that the mating component 400 can be adapted to the testing of most connector products by setting the limiting groove 702 and controlling the gap between the two conductive clips 410. The pre-tightening structure ensures that the clamping force between the two conductive clips 410 is sufficient to press the pins of the connector product under test. Through simple structural design, mold opening is eliminated. One test structure can meet the testing needs of different products, or products with rapid updates and iterations, and products with clamping force requirements. This greatly saves high mold opening costs, reduces production and manufacturing time, and enables rapid testing and prototyping of connector products. In addition, the vertical connection of the first connecting end 210 and the second connecting end 220 of the second fixing member 200 also facilitates manual handling during testing, effectively saving space and solving the problem of insufficient space between the two connector products to be tested. The defined slot 701 facilitates the rapid positioning and docking of the connector under test, so that the pins 802 of the connector under test 800 can be accurately inserted between the two conductive clips for rapid testing.

[0032] It should be noted that the two test sections are electrically connected by a flexible flat cable 300. The end of the flexible flat cable 300 is pressed and fixed to one side of the first connection end 210 by a pressure block 600. The flexible flat cable 300 is electrically connected to the circuit on the PCBA board 500, and the conductive clip 410 is also electrically connected to the circuit on the PCBA board 500, so that the connector under test 800 can be tested through the test structure of this application. During testing, the tester holds the first connecting end 210 with one hand and uses the other hand to position the connecting part 801 of the connector under test 800 onto the slot 701 of one of the test parts. The tester then slowly pushes the connector under test 800 so that the pin 802 of the connector under test 800 slowly overcomes the pre-tightening structure and enters between the two conductive clips 410. The pre-tightening structure causes the conductive clips 410 to press against the pin 802 with a certain pre-pressure, ensuring that the pin 802 and the conductive clips 410 will not lose contact during the test. The flexible flat cable 300 allows for flexible adjustment of the angle and spatial position of the two test parts to adapt to the testing of different connectors under test 800.

[0033] In some embodiments, such as Figure 3 As shown, the end of the conductive clip 410 first extends obliquely to one side to form a first pre-tightening portion 4121, and then extends obliquely to the other side to form a second pre-tightening portion 4122. The first pre-tightening portion 4121 and the second pre-tightening portion 4122 constitute a pre-tightening structure. After the two conductive clips 410 are positioned in the limiting groove 702, the pre-tightening structures of the two conductive clips 410 abut against each other, which can accommodate the insertion of most of the connectors 800 under test 802. The two second pre-tightening portions 4122 form a flared shape, which facilitates the insertion of the pins 802. The conductive clip 410 is made of elastic metal.

[0034] like Figure 4 and 5 As shown, the first fixing member 100 is arranged with several channels, which pass through both ends of the first fixing member 100. The second connecting end 220 covers the top of the channels to form a limiting groove 702, as shown. Figure 6 As shown, the two conductive clips 410 are distributed vertically within the limiting groove 702, and neither of the two conductive clips 410 contacts the limiting groove 702. The limiting groove 702 has sufficient space for the pre-tightening structure of the two conductive clips 410 to deform in order to fit most of the connectors 800 under test.

[0035] In this embodiment, the conductive clip 410 includes a first segment 411 and a second segment 412 connected to each other. A pre-tightening structure is disposed on the second segment 412. The width of the first segment 411 is smaller than the width of the second segment 412. The channel includes a first groove segment 111 and a second groove segment 112. The width of the second groove segment 112 is adapted to the width of the second segment 412, and the width of the first groove segment 111 is adapted to the width of the first segment 411, so that the first groove segment 111 and the second groove segment 112 form a limiting step. The width of each slot 111 is about 0.2mm larger than the width of the first segment 411, and the width of the second slot 112 is 0.2mm larger than the width of the second segment 412. After the two conductive clips 410 are fixed in the limiting slot 702, the first segment 411 is located in the first slot 111 and one end is soldered to the PCBA board, and the second segment 412 is located in the second slot 112. The resulting limiting step avoids the conductive clips 410 from retracting into the limiting slot 702 due to excessive insertion and removal force over a long period of time, effectively extending the service life.

[0036] In other embodiments, two conductive clips 410 are arranged vertically in the limiting groove 702, with a distance of 0.6 mm between them. The bottom of the second groove segment 112 is 0.2 to 0.3 mm lower than the bottom of the first groove segment 111. The second connecting end 220 is recessed 0.2 to 0.3 mm below the position of the second groove segment 112. The recess formed by the lower bottom of the second groove segment 112 compared to the first groove segment 111 facilitates the movement of the pre-tightening structure. Similarly, the recess formed by the recess of the second connecting end 220 corresponding to the position of the second groove segment 112 is also used for the movement of the pre-tightening structure. The distance of 0.6 mm between the two conductive clips 410 enables the test structure to be compatible with the insertion of most of the pins 802 of the connector under test 800.

[0037] like Figure 4 As shown, the first fastener 100 has symmetrically arranged first notches 120 on both sides, such as... Figure 8 As shown, the second connecting end 220 is provided with a second notch 222 corresponding to the position of the first notch 120, as... Figure 10 As shown, the second notch 222 covers the first notch 120 to form a slot 701.

[0038] In other embodiments, such as Figure 4 and Figure 5 As shown, the first fastener 100 has a first groove 130 at the end away from the pre-tightening structure, such as... Figures 7 to 9 As shown, the second connecting end 220 is provided with a second groove 221 at the position corresponding to the first groove 130. The first groove 130 and the second groove 221 cooperate to position and limit the PCBA board 500, which facilitates the installation of the PCBA board 500.

[0039] Furthermore, such as Figure 9 As shown, the first connecting end 210 has a clearance groove 211 on one side for fixing the PCBA board 500. The clearance groove 211 is designed to accommodate electronic components on the PCBA board 500, making the entire test section compact and space utilization efficient.

[0040] Furthermore, the PCBA board 500 is provided with a fixing hole for positioning and fixing the docking member 400 at the position corresponding to the limiting groove 702. The docking member 400 is electrically connected to the circuit on the PCBA board 500. The cooperation between the first groove 130 and the second groove 221 also facilitates the quick alignment of the fixing hole on the PCBA board 500 with the docking member 400.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
