[0037] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can be a mediating element.

[0038] The technical solutions of the present utility model will be further illustrated below in conjunction with the drawings and through specific embodiments.

[0039] In a first aspect, the present embodiment provides an electric knife wire harness electrical test fixture, which is applied to the test of an electric knife wire harness, can reduce the risk of damaging the electric knife wire harness, and has high reliability.

[0040] As shown in Figure 1 , Figure 2 and Figure 5 , the electric knife wire harness 1 includes an electric knife pen end 11, a plug connector end 13, and a cable (not shown in the figure) connected between the two. The electric knife pen end 11 has a test position 12, for example, the test position 12 has a spring sheet, which needs to be pressed to realize electrical test of the electric knife wire harness 1. The electric knife wire harness electrical test fixture cooperates with a test machine 10 to realize electrical test of the electric knife wire harness 1.

[0041] Exemplarily, as shown in Figures 1 to 8 , the electric knife wire harness electrical test fixture is disposed on an operation platform (not shown in the figure), and the electric knife wire harness electrical test fixture includes a pen end fixed carrier 100, a gravity pressing assembly 200, and a lifting mechanism 300.

[0042] The pen end fixed carrier 100 is configured to position the electric knife pen end 11 and can expose the test position 12. In some optional embodiments, as shown in Figure 2 , the top surface of the pen end fixed carrier 100 is provided with a positioning groove 110, which accommodates and positions the electric knife pen end 11 to prevent the electric knife pen end 11 from moving during the test. In some optional embodiments, the positioning groove 110 is communicated with a taking and placing groove, which facilitates taking and placing of the electric knife pen end 11.

[0043] In this embodiment, the gravity pressing component 200 is positioned above the pen tip fixing carrier 100, such as... Figure 4 As shown, the gravity pressing component 200 has a planar pressing surface 210, which presses the test position 12. Furthermore, the gravity pressing component 200 undergoes free fall in the vertical Z direction, causing the pressing surface 210 to press the test position 12, thereby achieving electrical testing of the electric knife wiring harness 1. The gravity pressing component 200's ability to undergo free fall ensures that the force applied to the test position 12 is consistent each time, improving test consistency and preventing excessively large or small forces from affecting the accuracy of the electrical test.

[0044] For example, the lifting mechanism 300 is selectively connected to the gravity pressing component 200, that is, the lifting mechanism 300 has a connected state with the gravity pressing component 200 and an independent state without being connected to the gravity pressing component 200. When the lifting mechanism 300 is connected to the gravity pressing component 200, the lifting mechanism 300 drives the gravity pressing component 200 to move in the direction away from the test position 12, that is, drives the gravity pressing component 200 to move vertically upward, so as to drive the pressing surface 210 away from the test position 12, which facilitates the removal of the electric knife tip 11 or the replacement of the test position 12. When the lifting mechanism 300 is not connected to the gravity pressing component 200, the movement of the gravity pressing component 200 is not interfered with by the lifting mechanism 300. At this time, the gravity pressing component 200 can perform free fall motion in the vertical direction Z. It should be noted that in this embodiment, the lifting mechanism 300 and the gravity pressing component 200 are in a non-connected state, which can be understood as the gravity pressing component 200 not contacting the lifting mechanism 300 when it is in free fall until it contacts the test position 12, so that the lifting mechanism 300 will not interfere with the free fall of the gravity pressing component 200 and will not apply friction to the gravity pressing component 200.

[0045] The electrosurgical test fixture for the wire harness provided in this embodiment uses an electrosurgical pen tip 11, which is positioned by a pen tip fixing carrier 100. This allows the test position 12 to be positioned relative to the gravity pressing component 200 in the vertical Z direction. The gravity pressing component 200 can perform free fall motion in the vertical Z direction and press the test position 12 with its planar pressing surface 210. This reduces the risk of damaging the transparent high-voltage resistant tape of the electrosurgical pen tip 11, thereby reducing the scrap rate of the electrosurgical wire harness 1. On the other hand, it ensures the consistency of test parameters, reduces human error, and improves product yield. By setting a lifting mechanism 300, the gravity pressing component 200 can be lifted and reset after the test is completed, so as to facilitate the next test, thus improving the testing efficiency.

[0046] In order to further improve the consistency of the test parameters, in the embodiment, the height of the lifting mechanism 300 lifting the gravity pressing assembly 200 is the same, that is, the position of the gravity pressing assembly 200 when doing free fall is consistent, so that the force of the gravity pressing assembly 200 on the test position 12 is the same, improving the accuracy and reliability of the test.

[0047] Exemplarily, the weight of the gravity pressing assembly 200 in the embodiment can be set according to actual needs. For example, the weight of the gravity pressing assembly 200 in the embodiment is 200 grams.

[0048] The specific structure of the gravity pressing assembly 200 can be various. In the embodiment, as shown in Figure 2 and Figure 3 , the gravity pressing assembly 200 includes a pressing head 220 and a pressing body 230 connected in sequence in the vertical direction Z. Among them, the cross-sectional area of the pressing head 220 is smaller than that of the pressing body 230, the pressing surface 210 is arranged at one end of the pressing head 220 away from the pressing body 230, and the lifting mechanism 300 is selectively connected to the pressing body 230. By making the cross-sectional area of the pressing head 220 smaller than that of the pressing body 230, in this way, the pressing head 220 can be thinner, and the pressing body 230 can be thicker, so that while ensuring that the pressing head 220 accurately presses on the test position 12, the weight of the gravity pressing assembly 200 can be larger to meet the pressing requirements of the test position 12.

[0049] The cross-sectional shape of the pressing head 220 and the pressing body 230 can be set according to actual needs. For example, the pressing head 220 and the pressing body 230 can both be cylindrical, and the pressing head 220 and the pressing body 230 are coaxially arranged to ensure that the pressing head 220 exerts a pressing force on the test position 12 in a direction perpendicular to the test position 12.

[0050] In order to improve the reliability of the selective connection of the pressing body 230 and the lifting mechanism 300, further optionally, as shown in Figure 3As shown, the outer peripheral surface of the pressing body 230 at the end away from the pressing head 220 is provided with a limiting protrusion 240, that is, the limiting protrusion 240 protrudes from the pressing body 230. In addition, the lifting mechanism 300 includes a lifting drive 310 and a limiting plate 320 connected to the output end of the lifting drive 310. The limiting plate 320 is arranged opposite to the pen end fixing carrier 100 in the vertical direction Z, and the pressing body 230 is movably arranged in the limiting plate 320 in the vertical direction Z, so that the limiting plate 320 does not affect the movement of the pressing body 230 in the vertical direction Z. The limiting protrusion 240 is arranged on the side of the limiting plate 320 away from the pen end fixing carrier 100. In this embodiment, the lifting drive 310 includes but is not limited to a cylinder, a linear motor, and other components capable of linear driving, and the present embodiment does not limit this.

[0051] When the gravity pressing assembly 200 needs to be lifted, the lifting drive 310 drives the limiting plate 320 to move vertically upward. When the limiting plate 320 contacts the limiting protrusion 240, the limiting plate 320 continues to move, which drives the pressing body 230 and the pressing head 220 to move vertically upward through the limiting protrusion 240, so that the pressing head 220 moves away from the test position 12, and the gravity pressing assembly 200 is reset. When the gravity pressing assembly 200 does not need to press the test position 12, it is always supported by the limiting plate 320 and kept in the initial position. When the gravity pressing assembly 200 needs to be free-falling, the lifting drive 310 drives the limiting plate 320 to quickly descend, and the descending speed of the limiting plate 320 is greater than the free-falling speed of the gravity pressing assembly 200, so that the limiting plate 320 no longer supports the limiting protrusion 240, and the limiting plate 320 does not touch the limiting protrusion 240 during the free-falling process of the gravity pressing assembly 200, so as to ensure that the gravity pressing assembly 200 contacts the test position 12 in the free-falling movement. It should be noted that when the pressing surface 210 of the gravity pressing assembly 200 contacts the test position 12 and presses the test shaft with a predetermined force, the limiting protrusion 240 can contact the limiting plate 320 or not contact the limiting plate 320, and the present embodiment does not limit this.

[0052] In order to facilitate the assembly of the pressing body 230 and the limiting plate 320, in this embodiment, please continue to refer to Figure 3 The limiting plate 320 is provided with a limiting groove 321. Specifically, the limiting plate 320 is arranged perpendicular to the vertical direction Z, and the limiting groove 321 is formed in the side surface of the limiting plate 320. The pressing body 230 is arranged through the limiting groove 321 in the vertical direction Z, and the limiting protrusion 240 is located outside the limiting groove 321. In this way, the pressing body 230 can move in the horizontal direction to enter or move out of the limiting groove 321, thereby realizing the detachable connection of the pressing body 230 and the limiting plate 320, facilitating the replacement of the gravity pressing assembly 200 with different weights, and improving the flexibility of the electrotome wire harness electrical testing fixture.

[0053] It should be noted that the cross-sectional dimension of the pressing body 230 is smaller than the size of the limiting groove 321, so that the limiting groove 321 cannot limit the movement of the pressing body 230 in the vertical direction Z. The sum of the cross-sectional dimension of the limiting protrusion 240 and the pressing body 230 is greater than the size of the limiting groove 321, so that the limiting protrusion 240 cannot enter the limiting groove 321, thereby enabling the lifting mechanism 300 to smoothly lift the gravity pressing assembly 200.

[0054] In order to prevent the size of the limiting plate 320 from being too large, in an embodiment, as shown in Figure 3 and Figure 4 The pressing body 230 includes a large-diameter section 231 and a small-diameter section 232 coaxially connected. The diameter of the large-diameter section 231 is greater than the diameter of the small-diameter section 232, and the small-diameter section 232 is movably arranged in the limiting plate 320, so that the size of the limiting groove 321 on the limiting plate 320 can be smaller, thereby enabling the size of the limiting plate 320 to be smaller, which is beneficial to the miniaturization and light weight of the electric knife wire harness electrical test fixture. The pressing head 220 in the present embodiment is coaxially connected with the large-diameter section 231, and the limiting protrusion 240 is arranged on the outer peripheral surface of the end of the small-diameter section 232 away from the large-diameter section 231.

[0055] By arranging the large-diameter section 231 and the small-diameter section 232, the lowest position of the limiting plate 320 can be limited. Specifically, when the lifting driving member 310 drives the limiting plate 320 to descend to abut against the end face of the large-diameter section 231 toward the end of the small-diameter section 232, the position of the limiting plate 320 is the lowest position, and at this time, the lifting driving member 310 stops driving the limiting plate 320 to descend.

[0056] In order to ensure that the pressing body 230 can ascend and descend in the vertical direction Z, in the present embodiment, as shown in Figures 1 to 3 The electric knife wire harness electrical test fixture further includes a support frame 400 and a guide member 500 arranged on the support frame 400. Specifically, the lifting mechanism 300 is arranged on the support frame 400, and the lifting driving member 310 is mounted on the support frame 400, and the limiting plate 320 is movably connected to the support frame 400. The guide member 500 is provided with a guide through hole 510 penetrating in the vertical direction Z, and the pressing body 230 is movably arranged in the guide through hole 510, so that the guide through hole 510 can support the pressing body 230 in the horizontal direction, thereby ensuring that the pressing body 230 moves in the vertical direction Z when the lifting mechanism 300 drives the pressing body 230 to move, and the pressing body 230 will not tilt, so that the pressing body 230 can be smoothly reset. It should be noted that the diameter of the guide through hole 510 is greater than the maximum diameter of the pressing body 230, thereby enabling the guide through hole 510 to not limit or interfere with the free fall movement of the pressing body 230.

[0057] Exemplarily, as shown in Figure 6 The support frame 400 includes a support plate 410 and a bracket 420 arranged on the support plate 410, and the lifting driving member 310 is arranged on the support plate 410. The bracket 420 is in a U shape and connected to the support plate 410, and the guide member 500 is connected to the bracket 420.

[0058] In some optional embodiments, the pressing head 220 is a plastic pressing head, that is, the part of the gravity pressing assembly 200 that contacts the test position 12 is a plastic pressing head, which can further reduce the risk of damaging the transparent high-pressure-resistant adhesive tape and will not cause the deformation of the shell of the electric pencil end 11, avoiding the abnormal performance of the electric pencil wire harness 1, further improving the reliability and quality of the test, and reducing the scrap rate of the electric pencil wire harness 1.

[0059] In an implementable manner, as shown in Figure 2 The electric pencil end 11 has a plurality of test positions 12 arranged at intervals in the first direction X. Among them, Figure 2 The case where the electric pencil end 11 includes two test positions 12 is shown. As shown in Figure 1 and Figure 6 The electric pencil wire harness electrical test fixture further includes a translation driving member 600. Among them, the pencil end fixing carrier 100 is connected to the output end of the translation driving member 600, and the translation driving member 600 drives the pencil end fixing carrier 100 to move in the first direction X to adjust the position of the pencil end fixing carrier 100 in the first direction X, so that different test positions 12 are located directly below the pressing surface 210, thereby realizing the test of each test position 12, improving the test efficiency and test automation, and reducing the labor intensity. In this embodiment, the translation driving member 600 includes but is not limited to components such as air cylinders and linear motors that can be linearly driven, and this embodiment does not limit it. In some optional embodiments, the first direction X is the length direction of the pencil end fixing carrier 100, and the width direction of the pencil end is the second direction Y.

[0060] Optionally, as shown in Figure 1 or Figure 6 One end of the pencil end fixing carrier 100 is provided with a first plug-in seat 700. The electric pencil end 11 is plugged into the first plug-in seat 700 and electrically connected with the first plug-in seat 700. The first plug-in seat 700 is electrically connected with the test machine 10 of the electric pencil wire harness electrical test equipment, thereby forming a test loop. In this embodiment, the first plug-in seat 700 is directly connected to the pencil end fixing carrier 100, so that the electric pencil end 11 can be electrically connected to the pencil end fixing carrier 100 while being positioned on the pencil end fixing carrier 100, so that the two steps are performed at the same time, reducing the assembly steps in the test process. In this embodiment, the first plug-in seat 700 is arranged at one end of the pencil end fixing carrier 100 in the first direction X.

[0061] In some optional embodiments, the first socket 700 contacts the electric knife pen end 11 in a POGO PIN contact (also known as a spring needle contact), which can reduce the risk of the opening size of the electric knife pen end 11 exceeding the tolerance caused by the test process, ensure the test reliability of the electric knife wire harness 1, and avoid damage to the electric knife wire harness 1.

[0062] In a second aspect, the embodiment also provides an electric knife wire harness electrical test device, which includes the test machine 10 and the electric knife wire harness electrical test fixture as in the first aspect. The electric knife pen end 11 is electrically connected to the test machine 10. The electric knife wire harness electrical test device provided by the embodiment can have high reliability and extremely high test efficiency.

[0063] In some optional embodiments, as shown in Figure 1 or Figure 5 The electric knife wire harness electrical test device further includes a second socket 20, and the plug connector end 13 of the electric knife wire harness 1 is connected to the second socket 20.

[0064] For example, the second socket 20 can be provided with multiple sockets, and the electric knife wire harness electrical test fixture is correspondingly provided with multiple sockets, so that the simultaneous testing of multiple electric knife wire harnesses 1 can be realized, and the test efficiency is improved.

[0065] When using the electric knife wire harness electrical test device provided by the embodiment, first, the parameters of the test machine 10 are set, the plug connector end 13 of the electric knife wire harness is sequentially inserted into the second socket 20, and the electric knife pen end 11 is positioned on the pen end fixing carrier 100 and simultaneously inserted into the first socket 700. At this time, the electric knife wire harness 1 and the test machine 10 form a test loop, and the test machine 10 displays qualified parameters. At this time, the gravity pressing assembly 200 is limited by the lifting mechanism 300 and located above the pen end fixing carrier 100. When testing the performance of the electric knife wire harness 1, specifically, the lifting drive 310 is controlled to act and push the limiting plate 320 to descend, and the gravity pressing assembly 200 slowly free-falls under the action of its own weight, the pressing surface 210 contacts a test position 12, and the test machine 10 gives a test signal. After the test is passed, the lifting drive 310 drives the limiting plate 320 to rise, and the entire gravity lifting assembly is driven to rise by the limiting protrusion 240, so that the pressing surface 210 moves away from the test position 12. After the gravity pressing assembly 200 is reset, the lifting drive 310 stops acting.

[0066] Next, the translation driver 600 is actuated, and the pen end fixed carrier 100 is moved in the first direction X until the other test position 12 of the electrotome pen end 11 is directly below the pressing surface 210. After that, the control lifting driver 310 is actuated to test the other test position 12, and the testing machine 10 gives a test signal.
