The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

Example one

Referring to fig. 1 to 7, an embodiment of the invention provides a flat cable testing device, which includes a testing base 1 and a flip 2 hinged to the testing base 1;

the test base 1 comprises a fixed base 11, a probe base 12 and a probe 13; the probe seat 12 is movably embedded on the fixed seat 11 up and down; one end of the probe 13 is fixedly arranged on the fixed seat 11, and the other end of the probe is arranged in the probe seat 12 in a penetrating manner;

the fixed seat 11 is provided with a fool-proof limiting mechanism 14, and the fool-proof limiting mechanism 14 is composed of a fixed block 141, a movable block 142 and a first elastic part 143 arranged between the fixed block 141 and the movable block 142;

a limiting part 144 which is contacted with the probe seat 12 and limits the downward movement of the probe seat 12 is arranged 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.

The flip cover 2 is provided with a foolproof pressing block 3 matched with the foolproof limiting mechanism 14 for use;

when the flip cover 2 is turned over and pressed down, the fool-proof press block 3 is pressed down to push the movable block 142 in a direction away from the probe base 12 until the limiting part 144 is disconnected from the probe base 12, so that the probe base 12 can move down along with the pressing of the flip cover 2, and the probe 13 can extend out of the probe base 12 and then is connected with a metal sheet of a flat cable for testing.

The first elastic element 143 is a spring or an elastic plastic, preferably a spring.

In this embodiment, a first inclined plane is disposed at one end of the foolproof press block 3, which is in contact with the movable block 142;

the movable block 142 is provided with a second inclined surface adapted to the first inclined surface.

It should be noted that the inclination angles of the first inclined plane and the second inclined plane are complementary, and the reason for this is that when the fool-proof press block 3 is pressed down, the fool-proof press block can smoothly continue to be pressed down along the second inclined plane by the first inclined plane, so as to push the movable block 142 in a direction away from the probe base 12.

In this embodiment, the probe socket 12 includes an inner mold plate 121 and a carrier plate 122;

the inner template 121 is embedded in the fixed seat 11, and a second elastic part is connected between the inner template and the fixed seat 11;

the carrier plate 122 is embedded on the inner template 121 and is fixedly connected with the inner template 121;

a probe hole 123 is formed in the position of the carrier plate 122 corresponding to the probe 13.

Wherein the number of the probe holes 123 is the same as that of the probes 13; the second elastic member may be a spring or an elastic plastic like the first elastic member 143.

It should be noted that, since the carrier plate 122 is fixedly connected to the inner mold plate 121, when the inner mold plate 121 is pressed to move downward, the carrier plate 122 also moves downward (actually, the carrier plate 122 is also pressed by the downward force of the flip 2), that is, the inner mold plate 121 and the carrier plate 122 move synchronously, and similarly, when the inner mold plate 121 is not pressed (that is, the flip 2 is opened), the inner mold plate 121 moves upward due to the acting force of the spring (that is, the elastic force provided when the spring returns to deform), and at this time, the carrier plate 122 also moves upward under the driving of the inner mold plate 121. In view of saving parts, the embodiment only exemplifies that a spring is disposed between the inner mold plate 121 and the fixing seat 11, but a spring may be disposed between the carrier plate 122 and the fixing seat 11, or springs may be disposed between the inner mold plate 121 and the carrier plate 122 and the fixing seat 11 as required.

In this embodiment, the testing base 1 further includes a pre-pressing plate 4;

the pre-pressing plate 4 is hinged to the inner mold plate 121 and is used for pressing and limiting the flat cable to be tested on the carrier plate 122.

It should be noted that the pre-pressing plate 4 can ensure that the flat cable to be tested placed on the carrier plate 122 does not move or shift, so that the probes 13 extending from the probe holes 123 can be accurately inserted onto the metal sheets of the flat cable during testing.

In this embodiment, the fixing base 11 includes a fixing base main body 111 and a bottom plate 112;

the fixing seat main body 111 is provided with a through hole penetrating through the upper wall and the lower wall of the fixing seat main body 111;

the bottom plate 112 is disposed in the through hole and is fixedly connected to the fixing base main body 111 to form a groove with the bottom plate 112 as a groove bottom for the inner mold plate 121 to be embedded.

In this embodiment, the bottom plate 112 is provided with a guiding post for guiding;

the inner mold plate 121 is provided with a guide groove corresponding to the guide post.

Preferably, the fixing block 141 and the fixing base main body 111 are integrally formed or fastened.

In this embodiment, the fixing seat main body 111 is provided with a fastening component 5;

and a clamping hook component 6 matched with the clamping component 5 for use is arranged at the position, corresponding to the clamping component 5, on the flip cover 2.

The fool-proof principle of the fool-proof limiting mechanism 14 is explained as follows:

when the test is not performed (when the flip cover 2 is opened), the movable block 142 is subjected to a spring pressure in the direction of the probe base 12, so that the movable block 142 can be pushed to the lower side of the probe base 12 to abut against the probe base 12, and as long as the probe base 12 is not subjected to a force enough to damage the movable block 142, the probe 13 cannot be exposed no matter how to press, and the contact of external pollutants or the accidental touch of a human hand is avoided;

when a test is performed (when the flip cover 2 is closed), along with the downward pressing of the flip cover 2, the fool-proof press block 3 pushes the movable block 142 along the second inclined plane towards a direction away from the probe base 12 through the first inclined plane until the movable block 142 is separated from the bottom of the probe base 12, at this time, the limiting effect of the movable block 142 on the probe base 12 disappears, the probe base 12 is pressed downward, and the probe 13 is relatively lifted upward to perform a wire arrangement test.
