Description

Technical Field

[0001] The utility model relates to the technical field of impact force testing, in particular to a connector impact force tester. Background Art

[0002] A connector, also known as a connector, is a device used to connect circuits. It typically consists of a plug and a socket. The plug connects to one end of the circuit or device, and the socket accepts the other end of the plug. The main function of a connector is to transmit current or signals through contact between the plug and the socket, thereby ensuring the normal operation of electrical equipment.

[0003] After the connector is manufactured, it needs to be tested for performance and reliability using an impact tester. Existing impact testers place the connector on a test platform, drop a hammer to hit the surface of the connector, and then test whether the performance of the connector is affected by the impact. Since there is often a height difference between the plug and socket of the connector, after it is placed on the test platform, the plug part does not contact the surface of the test platform. When the hammer drops, the weight of the hammer falls entirely on the socket part. Under normal use, the socket and plug are both connected to the object, rather than the plug part being suspended in the air. Therefore, there is a difference between the test scenario simulation and the actual working scenario, which will cause the test results to be inaccurate. Utility Model Content

They are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0034] like Figure 1-Figure 7 As shown, a connector impact force tester includes a test cylinder 100, a drive box 200, a first carrier block 310, a second carrier block 320, a drive assembly 400 and a drop hammer group. The test cylinder 100 is set at the top center of the drive box 200. The top of the drive box 200 has a connecting groove 210, which connects the test cylinder 100 and the inside of the drive box 200. The first carrier block 310 and the second carrier block 320 are used to carry the connector. The upper surfaces of the first carrier block 310 and the second carrier block 320 are The first carrier block 310 and the second carrier block 320 are arranged in the connecting groove 210 and the two are slidably abutted against each other. The driving assembly 400 is arranged in the driving box 200. The driving assembly 400 is used to drive the first carrier block 310 and the second carrier block 320 to move in opposite directions in the vertical direction. The drop hammer assembly 500 is arranged in the test cylinder 100 and is located above the first carrier block 310 and the second carrier block 320. The drop hammer assembly 500 can fall freely in the test cylinder 100, thereby applying an impact force to the docking plug.

[0035] When in use, the staff first measures the height difference between the plug and socket parts of the connector with a vernier caliper, and then adjusts the first carrying block 310 and the second carrying block 320 to the corresponding height difference position, so that the height difference between the upper surfaces of the first carrying block 310 and the second carrying block 320 is equal to the height difference between the plug and socket parts of the connector. Specifically, the driving component 400 is started, and the driving component 400 drives the first carrying block 310 and the second carrying block 320 to move in opposite directions in the vertical direction, so that the height difference between the first carrying block 310 and the second carrying block 320 is equal to the height difference between the plug and socket parts of the connector. At this time, the connector is placed on the first carrying block 310 and the second carrying block 320. (For example, if the upper surface height of the first loading block 310 is higher than the upper surface height of the second loading block 320, the socket of the connector is in surface contact with the second loading block 320, and the plug of the connector is in surface contact with the first loading block 310. At this time, the drop hammer assembly 500 is activated, and the drop hammer assembly 500 drops to impact the connector, thereby completing the impact force test of the connector. Compared with the existing impact force tester, the present invention provides a first loading block 310 and a second loading block 320 with an adjustable height difference. Therefore, when the plug and socket of the connector are subjected to the impact force of the drop hammer, both the plug and the socket are supported, rather than the plug part 523 being suspended in the air. Therefore, the difference between the test scenario simulation and the actual working scenario is smaller, and the test results are more accurate.

[0036] In a further embodiment, Figure 5 As shown, the drive assembly 400 includes a first threaded block 410, a second threaded block 420 and a bidirectional screw 430. The first threaded block 410 is arranged on one side of the first carrying block 310, and the second threaded block 420 is arranged on the side of the second carrying block 320 close to the first carrying block 310. The bidirectional screw 430 is vertically arranged in the drive box 200. The first threaded block 410 is threadedly connected to the lower part of the bidirectional screw 430, and the second threaded block 420 is threadedly connected to the upper part of the bidirectional screw 430. The bidirectional screw 430 can rotate around its axis.

[0037] During use, if the height difference needs to be increased, the bidirectional screw 430 is rotated around its axis, and the bidirectional screw 430 drives the first threaded rod and the second threaded block 420 away from each other. At this time, the first threaded block 410 drives the first carrying block 310 to move downward, and the second threaded block 420 drives the second carrying block 320 to move upward, thereby increasing the height difference between the upper surface of the first carrying block 310 and the lower surface of the second carrying block 320.

[0038] In a further embodiment, Figure 5As shown, the drive assembly 400 also includes a first bevel gear 440, a second bevel gear 450, a first motor 460 and a fixed base 470. The fixed base 470 is arranged in the drive box 200, the first motor 460 is arranged on the fixed base 470, the output shaft of the first motor 460 is fixedly connected to the second bevel gear 450, the first bevel gear 440 is coaxially arranged on the outer periphery of the bidirectional screw 430, and the first bevel gear 440 is meshed with the second bevel gear 450.

[0039] When the bidirectional screw 430 needs to rotate around its axis, the first motor 460 is started, and the output end of the first motor 460 drives the second bevel gear 450 to rotate, the second bevel gear 450 drives the first bevel gear 440 to rotate, and the first bevel gear 440 drives the bidirectional screw 430 to rotate, thereby realizing the bidirectional screw 430 rotating around its axis.

[0040] In a further embodiment, Figure 5 As shown, a hydraulic support member 480 is further provided in the driving box 200 , and the telescopic end of the hydraulic support member 480 is fixedly connected to a support plate 481 , and the support plate 481 is parallel to the lower surfaces of the first loading block 310 and the second loading block 320 .

[0041] During use, after the height difference adjustment between the first loading block 310 and the second loading block 320 is completed, the hydraulic support 480 is started so that the telescopic end of the hydraulic support 480 drives the support plate 481 to move upward until the upper surface of the support plate 481 contacts the lower surface of the first loading block 310 and the lower surface of the second loading block 320.

[0042] The hydraulic support member 480 and the support plate 481 are provided to protect the bidirectional screw 430 and prevent the bidirectional screw 430 from being broken due to the impact force when the hammer is dropped.

[0043] In a further embodiment, Figure 1 and Figure 6 As shown, the drop hammer assembly 500 includes an electromagnetic suction cup 510, an impact hammer head 520, a rotating screw 530 and a support frame 540. Two slide slots 550 are provided at the upper end of the test cylinder 100. The slide slots 550 extend downward in the vertical direction. Both ends of the electromagnetic suction cup 510 pass through the slide slots 550 and are threadedly connected to the rotating screw 530. The rotating screw 530 is arranged vertically. A second motor 560 is provided in the drive box 200. The output end of the second motor 560 is coaxially fixedly connected to the rotating screw 530. The impact hammer head 520 is magnetically connected to the lower end of the electromagnetic suction cup 510.

[0044] A fixed base 600 is provided at the bottom of the driving box 200 , and a support frame 540 is provided on the fixed base 600 . The upper end of the rotating screw 530 is rotatably connected to the support frame 540 .

[0045] When the drop hammer assembly 500 needs to work, the electromagnetic suction cup 510 is first started, and then the second motor 560 is rotated, and the rotating screw 530 is driven to rotate by the second unit, and the electromagnetic suction cup 510 is driven to move upward to the required height position by the rotating screw 530. The electromagnetic suction cup 510 drives the impact cone head to move to the required height position, and then the electromagnetic suction cup 510 is powered off, and the impact hammer head 520 falls freely under the action of gravity. At this time, the impact hammer head 520 impacts the connector, thereby completing the impact force test of the impact hammer head 520 docking with the connector.

[0046] After the test is completed, the second motor 560 drives the rotating screw 530 to rotate in the opposite direction, and the reverse rotation of the rotating screw 530 drives the electromagnetic suction cup 510 to move down to a position in contact with the impact hammer head 520. At this time, the electromagnetic suction cup 510 is energized, and the impact hammer head 520 is tightly attracted by the magnetic force generated by the electromagnetic suction cup 510.

[0047] In a further embodiment, Figure 6 As shown, the impact hammer head 520 includes a tail 521, a rod 522 and a head 523. The tail 521 is an iron ring with a threaded hole in the center of the lower end face of the iron ring. The rod 522 is threadedly connected in the threaded hole. A weight 524 of the required weight is mounted on the rod 522, and the head 523 is arranged at the lower end of the rod 522.

[0048] When the weight of the weight 524 needs to be adjusted, the staff unscrews the tail 521 from the rod 522, then puts the required weight 524 on the rod 522, and then screws the tail 521 and the rod 522 together. In this way, the size of the impact force can be changed by the weight of the weight 524.

[0049] In a further embodiment, Figure 1 As shown, a first box door 110 is hinged on the side of the driving box 200 .

[0050] The first box door 110 is provided to facilitate maintenance of the driving components inside the driving box 200 .

[0051] In a further embodiment, Figure 1 As shown, a second door 220 is hingedly connected to the lower portion of the test cylinder 100 .

[0052] The second door 220 is provided to facilitate the staff to place the connector on the first loading block 310 and the second loading block 320 and to load the weight 524 on the rod 522 of the impact hammer 520 .

[0053] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, 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.

[0054] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
