For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within 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.
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] like Figures 1 to 4 As shown, the horizontal testing device for male terminal plastic shells in this embodiment includes: a connecting platform 1, fixedly installed on a testing table; a testing cavity 2, one end of which is rotatably connected to the connecting platform 1, and the testing cavity 2 rotates around the connecting platform 1; a positioning block 3, disposed on one side of the connecting platform 1; the testing cavity 2 includes an outer cavity 21, an inner cavity 22, and a testing point 23, the outer cavity 21 being disposed on one side of the testing cavity 2, the inner cavity 22 being disposed within the outer cavity 21, and the testing point 23 being disposed within the inner cavity 22; and an airlock mechanism, disposed on the connecting platform 1, the testing cavity 2 having a locking hole for cooperating with the airlock mechanism, the airlock mechanism being used to lock the testing cavity 2.
[0030] A guide groove 211 is provided on the inner edge of the outer cavity 21, and a first switch pin 212 is provided inside the outer cavity 21.
[0031] A second switch pin 213 is provided inside the outer cavity 21.
[0032] A reset spring 4 is provided between the connecting platform 1 and the test chamber 2.
[0033] The connection platform 1 is equipped with a trigger switch 11 and an unlock switch 12. Both the trigger switch 11 and the unlock switch 12 are connected to the airlock mechanism and are used to control the extension and retraction of the airlock mechanism.
[0034] The trigger switch 11 is located within the positioning area formed by the two positioning blocks 3. A ball spring screw 31 is installed within each positioning block 3. Adjusting the position of the ball spring screw 31 allows for clamping and positioning of the outer surface of the plastic shell. One end of the ball spring screw 31 is a rotating ball, and the other end is a threaded post. A spring is installed between the threaded post and the rotating ball. The threaded post is threaded into the positioning block 3, and rotating the threaded post changes the extension length.
[0035] Test chamber 2 is made of PP material. PP material is polypropylene, which has good moldability and produces lightweight products.
[0036] like Figures 5 to 7 As shown, during use, supported by the reset spring 4, the test chamber 2 and the connecting platform 1 are at a certain angle, here 45°. The plastic shell with a locking clip is inserted into the test chamber 2, and the test chamber 2 is pressed until the angle between the test chamber 2 and the connecting platform 1 is 0°. At this time, the trigger switch 11 is squeezed, the airlock mechanism extends, and the test chamber 2 is fixed. The detection mechanism inside the test chamber 2 detects the plastic shell. The first switch pin 212 is used to detect whether the plastic shell is in place, and the second switch pin 213 is used to detect whether the locking clip is in place (or to detect the presence of the locking clip). The test point 23 is used to detect whether the male terminal pin inside the plastic shell is in contact (if not in contact, it indicates that the pin is bent, and the product is unqualified). The guide groove 211 is designed to prevent the pin from being affected during insertion and to prevent bending. After the test is completed, the unlocking switch 12 is pressed. The unlocking switch 12 releases the airlock mechanism from restricting the test chamber 2. Under the elastic force of the reset spring 4, the test chamber 2 returns to its original position, and the plastic shell is pulled out, completing the test. The test data is stored in a computer and can be used to display the yield rate.
[0037] The utility model discloses a rotating connection design through the connecting platform and the test cavity, so that the device is more flexible when operating, and the plastic shell is convenient for inserting and taking out. The horizontal type test of the plastic shell is realized. The ball spring screw design of the positioning block ensures the accurate position of the plastic shell when testing, and improves the accuracy and repeatability of the test. Through setting the outer cavity, the inner cavity and the test point, the multifunctional detection of whether the plastic shell is in place, whether the lock catch is in place and whether the male terminal pin contacts is realized, and the quality of the plastic shell is comprehensively evaluated. The setting of the guide groove effectively avoids the damage of the pin when entering the test cavity, ensures the straightness of the pin and reduces the generation of unqualified products. The cooperation design of the airlock mechanism and the locking hole ensures the stable locking of the test cavity during the detection process, and guarantees the smooth detection. The design of the trigger switch and the unlocking switch makes the control of the airlock mechanism more simple, and the operator can easily complete the control of the test process.
