Description

Technical Field

[0001] This utility model relates to a cable testing device with terminals. Background Technology

[0002] With the advancement of electronic technology, electronic products are becoming denser, smaller, and have more channels, which has driven the stringent and efficient technical requirements for high-frequency testing of antennas and transmission lines with high-frequency terminals. Specifically, the terminal testing methods for cables need to meet the requirements of protecting products, providing accurate test results, and being easy to use.

[0003] The components of the high-frequency terminal have certain tolerances in the products they are assembled with. After the cable has been bent multiple times, the end face of the high-frequency terminal is no longer parallel to the DUT body at the other end of the cable. As a result, when the terminal is placed in the terminal positioning block, it will not fall freely into the positioning cavity. In reality, the high-frequency terminal is placed at an angle in the positioning cavity, or due to the flexibility and elasticity of the cable, the terminal cannot be placed in the terminal positioning block. This results in poor test stability, consistency and accuracy.

[0004] In view of this, it is necessary to improve the existing cable testing equipment with terminals in order to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cable testing device with terminals to solve the problem of poor testing stability, consistency and accuracy caused by defects in existing cable positioning methods.

[0006] To achieve the above objectives, this utility model provides a cable testing device with terminals for testing cables with terminals. The cable testing device with terminals includes a positioning component and a detection component. The positioning component includes a positioning block for placing the cable, a pre-pressing block for pressing the terminal against the positioning block, and a driving component for driving the pre-pressing block to press the terminal against the terminal. The pre-pressing block presses against a portion of the terminal. The pre-pressing block has an exposure groove that extends vertically through the exposure groove, and the terminal is exposed from the exposure groove. The positioning block has a positioning cavity for placing the terminal, and a positioning protrusion extends upward from the positioning cavity. The detection component includes a probe for detecting the terminal. The probe is inserted into the exposure groove to detect the terminal.

[0007] As a further improvement of this utility model, the positioning block includes two positioning protrusions, the cable is used to hold between the positioning protrusions, the positioning protrusions are provided with guide holes, and the detection element also includes a guide pin, the guide pin is used to insert into the guide hole.

[0008] As a further improvement of this utility model, when the pre-pressing block presses against the terminal, the pre-pressing block abuts against the positioning protrusion in the horizontal direction.

[0009] As a further improvement of this utility model, the driving component includes a guide and a side-push connecting block. One end of the side-push connecting block is connected to the pre-compression block. The side-push connecting block is slidably arranged along the guide to drive the pre-compression block to move in the horizontal direction.

[0010] As a further improvement of this utility model, the guide member is inclined and gradually rises in the direction away from the positioning block.

[0011] As a further improvement of this utility model, the drive assembly also includes a cover opening handle, which is fixed to the end of the side push connecting block away from the pre-compression block.

[0012] As a further improvement of this utility model, the drive assembly further includes a blocking block and a return spring. The blocking block is disposed on the side of the cover opening handle away from the side push connecting block, and the return spring abuts against the blocking block and the cover opening handle or the side push connecting block.

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figures 1 to 8 As shown, the cable testing device 100 with terminals of this utility model is used to test the cable 200 with terminals 201.

[0021] The cable testing device 100 with terminals includes a positioning element 1 and a testing element 2.

[0022] The positioning element 1 is used to position the terminal 201 to ensure that the terminal 201 is set horizontally, so as to facilitate the vertical detection by the detection element 2.

[0023] like Figure 8 As shown, the detection element 2 includes a probe 21 for detecting the terminal 201, a guide pin 22 for positioning, and a mounting guide block 23. The probe 21 is inserted into the exposure groove 121 to detect the terminal 201. Both the guide pin 22 and the probe 21 extend vertically during use. The guide pin 22 and the probe 21 are mounted within the mounting guide block 23.

[0024] like Figures 1 to 7 As shown, the positioning component 1 includes a positioning block 11 for placing the cable 200, a pre-pressing block 12 for pressing the terminal 201 against the positioning block 11, a driving assembly 13 for driving the pre-pressing block 12 to press against the terminal 201, and a base plate 14.

[0025] The positioning block 11 is fixed to the base plate 14. The positioning block 11 includes two positioning protrusions 111 and a positioning cavity 112. The positioning protrusions 111 extend upward from the positioning cavity 112, and the cable 200 is held between the positioning protrusions 111. The positioning protrusions 111 are provided with guide holes 113. The two positioning protrusions 111 are spaced apart, and the spacing is equal to the diameter of the cable 200. The positioning protrusions 111 can prevent the cable 200 from shaking. In this embodiment, the cable 200 and the terminal 201 at the end are both housed in the positioning cavity 112.

[0026] The guide pin 22 is inserted into the guide hole 113. Before the probe 21 contacts the terminal 201, the guide pin 22 is first inserted into the guide hole 113 to ensure that the position of the terminal 201 and the position of the probe 21 are within the specified range for probe 21 testing. This improves the stability of the probe 21 contacting the terminal 201 and ensures the consistency and accuracy of product testing.

[0027] The positioning cavity 112 is used to place the terminal 201. The positioning cavity 112 is located on the side of the positioning protrusion 111 facing the pre-pressing block 12. The positioning cavity 112 is formed by recessing downward from the surface of the positioning block 11.

[0028] The pre-compression block 12 presses against the terminal 201, primarily against the end of the terminal 201 furthest from the cable 200. The pre-compression block 12 has an exposure groove 121 extending vertically through it, through which the terminal 201 is exposed. The pre-compression block 12 can press the terminal 201 into the positioning cavity 112. (See also...) Figure 7,Book When the pre-pressing block 12 presses against the terminal 201, the pre-pressing block 12 abuts against the positioning protrusion 111 in the horizontal direction.

[0029] like Figure 2 and Figure 3 As shown, the drive assembly 13 includes a guide 131, a guide rail mounting block 132, a side push connecting block 133, a cover opening handle 134, a blocking block 135, and a reset spring 136.

[0030] The guide rail mounting block 132 and the blocking block 135 are fixed on the base plate 14.

[0031] The guide member 131 is fixed on the guide rail mounting block 132. The guide member 131 is located on the side of the positioning block 11 where the positioning cavity 112 is provided, and extends toward the side away from the positioning block 11. In this embodiment, the guide member 131 is a linear guide rail. In other embodiments, the guide member can also be other forms of guide rail, guide sleeve, or bearing, as long as it can guide in a single direction.

[0032] In this embodiment, the guide member 131 is inclined and gradually rises in the direction away from the positioning block 11.

[0033] One end of the side-push connecting block 133 is connected to the pre-compression block 12. The side-push connecting block 133 is slidably disposed along the guide member 131 to drive the pre-compression block 12 to move in the horizontal direction. In this embodiment, before testing, the cable 200 is held between the positioning protrusions, and the terminal 201 is pre-placed in the positioning cavity 112. The pre-compression block 12 can press the terminal 201 tightly in the positioning cavity 112 to ensure the flatness of the terminal 201.

[0034] Furthermore, due to the inclined arrangement of the guide member 131, this embodiment achieves this by tilting the upper surface of the guide rail mounting block 132. This ensures that when the pre-pressure block 12 moves away from the terminal 201, the height of the pre-pressure block 12 is higher than that of the terminal 201. As the pre-pressure block 12 gradually approaches the terminal 201, it gradually presses down. Even if the terminal 201 is uneven or has manufacturing tolerances, the pre-pressure block 12 can simultaneously approach the terminal 201 in both horizontal and vertical directions. At the end of the movement, the pre-pressure block 12 will contact the terminal 201, preventing prolonged contact time or excessive sliding friction between the pre-pressure block 12 and the end face of the terminal 201 during the movement, thus preventing scratches on the end face of the terminal 201. When the pre-pressure block 12 contacts the positioning block 11, there is a certain gap between the terminal 201 and the pre-pressure block 12 in all directions, preventing the terminal 201 from being statically damaged by the return spring 136.

[0035] Furthermore, the terminal 201 is placed obliquely within the positioning cavity 112, or due to the flexibility and elasticity of the cable 200, the terminal 201 cannot be placed horizontally within the positioning block 11. Instead, the terminal 201 is partially pressed down by the pre-pressure block 12, ensuring its end face remains vertically upward. The terminal 201 experiences a certain force between the pre-pressure block 12 and the positioning block 11, causing the pre-pressure block 12 to tend to open. The tilt angle of the inclined mounting block is less than the dynamic friction angle of the guide member 131. When the angle between the direction of the force applied by the terminal 201 and the direction of the movement speed of the pre-pressure block 12 is less than the dynamic friction angle of the guide member 131, the pre-pressure block 12 will not be pushed by the force generated by the flexibility and elasticity of the cable 200 due to the terminal 201, thus achieving a self-locking effect of the pre-pressure block 12.

[0036] The cover handle 134 is fixed to the end of the side push connecting block 133 away from the pre-compression block 12.

[0037] The blocking block 135 is disposed on the side of the lid opening handle 134 away from the side push connecting block 133, and the return spring 136 abuts against the blocking block 135 and the lid opening handle 134 or the side push connecting block 133. When the lid opening handle 134 or the side push connecting block 133 moves toward the blocking block 135, the return spring 136 is compressed. After the external force is removed, the return spring 136 moves toward the positioning block 11 under the action of elastic force. In this embodiment, the return spring 136 presses against the lid opening handle 134 and the blocking block 135.

[0038] Before testing, the user manually pushes the cover opening handle 134, causing the side push connecting block 133 and the pre-pressure block 12 to move away from the positioning block 11. The side push connecting block 133 slides along the guide member 131, and the reset spring 136 is compressed. After the cable 200 and the terminal 201 are placed, the user releases the cover opening handle 134. Under the elastic force of the reset spring 136, the cover opening handle 134, the side push connecting block 133 and the pre-pressure block 12 move toward the guide hole 113.

[0039] Since the pre-pressing block 12 self-locks when pressing the terminal 201, the spring force of the reset spring 136 does not need to be too large. It only needs to be greater than the resultant force of the dynamic friction force of the guide member 131 and the yield force of the cable 200 bending deformation, which makes it easier to save time and effort during operation.

[0040] The cable testing device 100 with terminals of this utility model, by setting a pre-compression block 12, presses the terminal 201 horizontally onto the positioning block 11, so that the end face of the terminal 201 is vertically upward, which facilitates the accurate contact of the probe 21, thereby improving the accuracy, stability and consistency of the test.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
