[0011] Preferably, the surface of the glue layer is provided with an anti-skid groove, the friction is improved, and the clamping force is improved. Beneficial effects

[0012] 1、In the prior art, in the production and detection process of electronic connectors, after careful examination of the pins by microscope, if no physical short-circuit signs can be found by naked eyes, the staff need to further test the continuity of the pins by using a multimeter, which often requires that the two contacts of the multimeter are respectively in contact with the pins, usually keeping one contact position unchanged, and the other contact is sequentially in contact with the remaining pins to detect whether there is a potential short circuit or continuity problem. However, this method is not only tedious and time-consuming, but also difficult to guarantee the accuracy and consistency of the test due to the need for manual operation to constantly change the contacts and ensure good contact each time. In actual work, errors caused by human factors are very common, for example, the operator may not be able to make the contact fully contact with the pin due to negligence or fatigue, or accidentally move the connector or multimeter during the test, resulting in inaccurate readings or even missing some hidden short circuit problems. These factors make the existing short circuit problems be missed, thereby affecting the quality and yield of the products. To solve such problems, the utility model adopts the installation of contact head, which realizes that when the staff need to test the short circuit condition of the electronic connector, the electronic connector is first fixed in the test box, the drive motor is started to rotate the threaded rod, the T rail is moved downward along the T rail slot through threaded connection, then the drive motor in the control matrix drives one of the fixed rotating wheels to rotate, the rotation is transmitted to the other fixed rotating wheels and the movable rotating wheel through the linkage belt, the linkage belt pulls the sliding piece through the movable rotating wheel, the sliding piece slides in the sliding groove, the contact head is in contact with the pins of the electronic connector, and the rotation of the motor continues to make the contact head contact with the pins of the electronic connector one by one, the multiple contact heads are connected with the built-in multimeter, if the multimeter reading is zero or emits a buzzing sound, it means that the pins are short-circuited, if there is no reading or buzzing, it means that there is no short circuit, achieving the effect of improving automation and increasing work efficiency.

[0013] 2、In the prior art, there is a lack of a relatively perfect and unified fixing method between electronic connectors of different models, which means that when the staff needs to detect the pins of the electronic connector, the stability and accuracy of the connector during the detection process cannot be ensured through a standardized operation process and tool. Specifically, in the detection operation, due to the lack of effective fixing measures, the electronic connector is prone to deviation when subjected to slight external force or slight vibration during the operation. For example, when the staff uses a detection instrument to perform contact detection on the pins, even extremely slight movement can cause the electronic connector to move on the workbench. This deviation phenomenon can seriously affect the detection result, making it difficult for the detection instrument to accurately align the pins, so that accurate detection data cannot be obtained. The low detection accuracy caused by the easy deviation of the electronic connector not only affects the control of product quality, increases the rate of defective products, but also reduces production efficiency to some extent and increases production cost, because inaccurate detection results may need to be repeatedly detected multiple times, or even cause product rework, wasting a large amount of time and resources. In view of such problems, the utility model adopts the installation of a chuck to solve the problem, so that when the detection starts, the staff places the electronic connector on the placement plate, starts the driving motor inside the test box to drive the screw rod to rotate. Since the threads of the chucks on both sides of the fixed rotating cylinder are opposite, the screw rod rotates the threaded connection, and at the same time, due to the limitation of the sliding connection between the bottom of the chuck and the trapezoidal groove, the chucks gather along the trapezoidal groove to the center, finally clamping the electronic connector on the top of the placement plate, so that the electronic connector is fixed during the detection, and the accuracy of the equipment is improved.

[0014] 3、The utility model adopts the installation of a special-shaped door, so that when the staff puts the electronic connector into the test box, the driving motor is started to make the L-arm link rotate and limit the movement track of the special-shaped door through the short connecting rod, finally shielding the cover door of the test box with the door beam to prevent personnel or sundries from entering by mistake, and the use safety of the equipment is improved.

[0047] The fixing measures ensure that the electronic connector is protected against slight external forces or minor vibrations during operation.

[0048] At this time, it is very easy for misalignment to occur. For example, when staff use testing instruments to connect the pins...

[0049] During touch testing, even the slightest movement can cause the electronic connector to tumble on the worktable.

[0050] Movement, this offset phenomenon, can severely affect the detection results, making it difficult for detection instruments to accurately measure the data.

[0051] The pins are not aligned correctly, making it impossible to obtain accurate test data. This is due to the ease with which electronic connectors can shift.

[0057] The collets 304 on both sides of 302 have opposite threads, and the screw 303 is rotated and threaded. Simultaneously, due to the collets 304...

[0058] The restriction of the sliding connection between the bottom and the trapezoidal groove 301 causes the clamp 304 to converge towards the center along the trapezoidal groove 301.

[0059] The final clamp holds the electronic connector on top of the placement plate 3, thereby keeping the electronic connector fixed during testing.

[0060] This will improve the accuracy of the equipment.

[0061] A drive motor 4 is fixed to one side of the test box 1, and an L-arm connecting rod 401 is fixed to one end of the drive motor 4.

[0062] One end of the arm connecting rod 401 is fixed with an irregularly shaped door 403. A short connecting rod 402 is rotatably connected to the inner wall of the test chamber 1.

[0063] One end of the connecting rod 402 is rotatably connected to an irregularly shaped door 403, and a door beam 404 is fixed to the inner wall of the test chamber 1.

[0064] The solution is achieved by installing an irregularly shaped door (403), allowing staff to place the electronic connector into the test chamber 1.

[0065] Then, the drive motor 4 is started, causing the L-arm connecting rod 401 to rotate and move the irregular door 403 via the short connecting rod 402.

[0066] The trajectory limitation is ultimately achieved by using the cover of the 404 shielding test box 1 to prevent personnel or debris from accidentally entering.

[0067] This improves the safety of equipment use. A rubber strip 5 is fixed to one side of the top of the control torque 203, achieving...

[0068] To prevent collisions between components and thus extend the lifespan of the equipment. The trapezoidal groove 301 has both ends of its inner wall...

[0069] Fixed collision soft points 6 prevent scratches between components, thereby extending the lifespan of the equipment.

[0070] As a result, one end of the chuck 304 is covered with a rubber layer 7, which cushions the chuck 304 to prevent damage to the electronic connection.

[0071] This device improves the yield rate of finished products. Anti-slip grooves are formed on the surface of adhesive layer 7 to increase friction.

[0072] This force is used to increase the clamping force.

[0073] The working principle of this invention is as follows: When staff need to test the short circuit condition of electronic connectors,

[0074] First, place the electronic connector in test chamber 1 and fix it in place. Then, start the drive motor 4 and rotate the adjusting threaded rod 2.

[0075] The threaded connection moves the T-rail member 202 downward along the T-rail groove 201, subsequently controlling the drive motor inside the torque 203.

[0076] Machine 4 drives one of the fixed rotating wheels 206 to rotate, and its rotation is transmitted to the others via the linkage belt 205.

[0077] The fixed rotating wheel 206 and the movable rotating wheel 207 cause the linkage belt 205 to pull the sliding member 209 through the movable rotating wheel 207.

[0078] The slider 209 slides within the slide rail 208, causing the contact head 2010 to contact the pins of the electronic connector.

[0079] And by continuing to rotate the motor, the contact head 2010 makes contact with the pins of the electronic connector one by one, multiple

[0080] All contacts 2010 are connected to the built-in multimeter. If the multimeter reading is zero or a beep is emitted, it indicates...

[0081] A short circuit between the pins should not produce a reading or beep, indicating no short circuit. Before testing begins, the operator should...

[0082] The operator places the electronic connector on the placement plate 3 and starts the drive motor 4 inside the test chamber 1 to drive the screw.

[0083] 303 rotates, and because the threads of the chucks 304 on both sides of the fixed-rotation cylinder 302 are opposite, the rotating screw 303 rotates through the threaded connection.

[0084] Meanwhile, due to the limitation of the sliding connection between the bottom of the chuck 304 and the trapezoidal groove 301, the chuck 304 is caused to move along the trapezoidal groove.

[0085] The slot 301 converges towards the center, ultimately clamping the electronic connector on top of the placement plate 3, thereby enabling electronic connection.

[0086] The instrument remains stationary during testing.
