Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of detection fixtures, and in particular to a cable testing device. Background Art

[0002] With the continuous development of electronic technology and people's increasing requirements for the thinness of electronic products, electronic products such as electronic watches are gradually developing towards a more integrated and sophisticated direction, the layout of internal components of the products is becoming more and more compact, and the manufacturing process is becoming more and more rigorous.

[0003] The flat cable in the electronic watch, also called flexible printed circuit (FPC), has many advantages such as small footprint and flexible appearance. It can easily connect the mainboard with multiple functional modules, such as distance sensor module, camera module and screen display module, and realize the functional control of these functional modules. Since the performance of the flat cable has a great influence on the performance of the electronic watch, in order to ensure the quality of the product, the performance of the flat cable needs to be tested after the production of the flat cable or before the assembly of the flat cable, so as to avoid the use of poor quality flat cables in the finished product.

[0004] At present, micron-level probes are generally used for electronic testing of the tiny flat cables in electronic watches. However, in actual use, the service life of micron-level probes is not high and they need to be replaced more frequently, resulting in high testing costs. The reason is that when the flat cable test module using micron-level probes is not tested, the micron-level probes are always exposed, which makes it very easy for people or objects to accidentally touch or collide with the probes and contaminate or damage them.

[0005] Therefore, how to improve the service life of the micron-level probes in the cable test module has become a technical problem that needs to be solved urgently in this field. Summary of the invention

[0050] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0051] Embodiment 1

[0052] Please refer to Figures 1 to 7 The embodiment of the present invention provides a cable testing device, which is composed of a test base 1 and a flip cover 2 hinged to the test base 1;

[0053] The test base 1 comprises a fixing base 11, a probe base 12 and a probe 13; the probe base 12 is embedded in the fixing base 11 movably up and down; one end of the probe 13 is fixedly disposed on the fixing base 11, and the other end is passed through the probe base 12;

[0054] The fixing seat 11 is provided with a foolproof limiting mechanism 14, which is composed of a fixed block 141, a movable block 142, and a first elastic member 143 provided between the fixed block 141 and the movable block 142;

[0055] A limiting portion 144 that contacts the probe seat 12 and limits the downward movement of the probe seat 12 is disposed on one side of the movable block 142 close to the probe seat 12 ; the limiting portion 144 and the movable block 142 are integrally formed or fastened together.

[0056] The flip cover 2 is provided with an anti-foolproof pressure block 3 used in conjunction with the anti-foolproof limit mechanism 14;

[0057] When the flip cover 2 is flipped over and pressed down, the anti-foolproof pressure block 3 is pressed down accordingly to push the movable block 142 away from the probe seat 12 until the limiting portion 144 breaks contact with the probe seat 12, so that the probe seat 12 can move downward as the flip cover 2 is pressed down, thereby allowing the probe 13 to extend from the probe seat 12 and then connect to the metal sheet of the cable for testing.

[0058] The first elastic member 143 is a spring or elastic plastic, preferably a spring.

[0059] In this embodiment, a first inclined surface is provided on the end of the anti-misbehavior pressure block 3 that contacts the movable block 142;

[0060] The movable block 142 is provided with a second inclined surface adapted to the first inclined surface.

[0061] It should be noted that the inclination angles of the first inclined surface and the second inclined surface are complementary. The reason for this arrangement is that when the anti-fouling pressure block 3 is pressed down, it can continue to press down along the second inclined surface smoothly with the help of the first inclined surface, thereby pushing the movable block 142 away from the probe seat 12.

[0062] In this embodiment, the probe seat 12 includes an inner template 121 and a carrier plate 122;

[0063] The inner template 121 is embedded in the fixing seat 11, and a second elastic member is connected between the inner template 121 and the fixing seat 11;

[0064] The carrier plate 122 is embedded in the inner template 121 and fixedly connected to the inner template 121;

[0065] A probe hole 123 is formed on the carrier board 122 at a position corresponding to the probe 13 .

[0066] The number of the probe holes 123 is the same as the number of the probes 13 ; the second elastic member, like the first elastic member 143 , can be a spring or elastic plastic.

[0067] It should be noted that, since the carrier plate 122 is fixedly connected to the inner template 121, when the inner template 121 is pressed and moves downward, the carrier plate 122 will also move downward (actually, it will also be subject to the downward pressure of the flip cover 2), that is, the movement of the inner template 121 and the carrier plate 122 is synchronous. Similarly, when the inner template 121 is not pressed (that is, when the flip cover 2 is opened), the inner template 121 will move upward due to the action of the spring (that is, the elastic force provided when the spring recovers its deformation), and at this time, the carrier plate 122 will also move upward driven by the inner template 121. In order to save parts, this embodiment only exemplifies that a spring is provided between the inner template 121 and the fixing seat 11, but in fact, a spring can also be provided between the carrier plate 122 and the fixing seat 11 as needed, or springs can be provided between the inner template 121 and the carrier plate 122 and the fixing seat 11.

[0068] In this embodiment, the test base 1 further includes a pre-pressing plate 4;

[0069] The pre-pressing plate 4 is hinged to the inner template 121 and is used to press and limit the cable to be tested on the carrier plate 122 .

[0070] It should be noted that the pre-pressing plate 4 can ensure that the tested flat cable placed on the carrier plate 122 does not move or deviate, so that the probe 13 extending from the probe hole 123 can accurately pierce the metal sheet of the flat cable during testing.

[0071] In this embodiment, the fixing seat 11 includes a fixing seat body 111 and a bottom plate 112;

[0072] The fixing seat body 111 is provided with a through hole penetrating the upper and lower walls of the fixing seat body 111;

[0073] The bottom plate 112 is disposed in the through hole and fixedly connected to the fixing seat body 111 to form a groove with the bottom plate 112 as the bottom for the inner template 121 to be embedded.

[0074] In this embodiment, the bottom plate 112 is provided with a guide column that can play a guiding role;

[0075] A guide groove used in conjunction with the guide post is provided at a position on the inner template 121 corresponding to the guide post.

[0076] Preferably, the fixing block 141 and the fixing seat body 111 are integrally formed or fastened together.

[0077] In this embodiment, a buckle assembly 5 is provided on the fixing seat body 111;

[0078] A hook assembly 6 for use with the buckle assembly 5 is provided on the flip cover 2 at a position corresponding to the buckle assembly 5 .

[0079] The foolproofing principle of the foolproofing limit mechanism 14 is described as follows:

[0080] When no test is performed (when the flip cover 2 is open), the movable block 142 is subjected to spring pressure in the direction of the probe seat 12, so that the movable block 142 is pushed under the probe seat 12 to support the probe seat 12, so that as long as the probe seat 12 is not subjected to a force sufficient to damage the movable block 142, the probe 13 will not be exposed no matter how it is pressed, thereby avoiding contact with external contaminants or accidental touch by human hands;

[0081] When testing (when the flip cover 2 is closed), as the flip cover 2 is pressed down, the anti-mismatch pressure block 3 pushes the movable block 142 away from the probe seat 12 along the second inclined surface through the first inclined surface until the movable block 142 is disengaged from under the probe seat 12. At this time, the limiting effect of the movable block 142 on the probe seat 12 disappears, the probe seat 12 can be pressed down, and the probe 13 is relatively lifted up to perform the wiring test.

[0082] A cable testing device provided by an embodiment of the present invention adds an anti-foolproof limit mechanism between the fixed seat and the probe seat, and cooperates with the anti-foolproof pressure block on the flip cover so that the probe is hidden in the probe seat in the non-testing stage and will not be exposed to the outside, thereby achieving the purpose of anti-foolproof limit when not testing and canceling the anti-foolproof limit when testing. The device is very stable and convenient, and avoids the situation where people or objects accidentally touch the probe and damage the probe, meeting the needs of extending the service life of the probe and reducing the cost of using the probe, and is suitable for large-scale promotion and application.

In order to thoroughly understand the embodiments of the present disclosure, numerous details are set forth, such as examples of specific parts, devices, and methods. Obviously, for those skilled in the art, it is not necessary to use specific details, the example embodiments can be implemented in many different forms, and neither should be construed as limiting the scope of the present disclosure. In certain example embodiments, well-known processes, well-known device structures, and well-known technologies are not described in detail.

[0085] Here, specialized vocabulary is used only for the purpose of describing specific example embodiments, and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a" and "the" used herein may be intended to include plural forms as well.
