Since the models of each interface of a laptop are inconsistent, different test heads corresponding to the interfaces need to be set. In the actual working environment, it is necessary to set up a dedicated material receiving mechanism for material receiving, and it is also necessary to set up a special test fixture to fix the test head in the working state. The material receiving mechanism accommodates multiple test heads at the same time. One side of the existing test head is a plug and the other side is a wire. When taking and placing the test mechanism, it is very easy for the wires of different test heads placed side by side to become entangled. Moreover, the existing test head is not easy to fix in the material receiving mechanism and the test fixture.
[0003] In view of this, it is necessary to provide a test head. Summary of the Invention

[0015] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the accompanying drawings.
[0016] Such as Figure 1 And Figure 2As shown in the figure, the test head provided by the embodiment of the present application has a structure including a housing 1, a PCB disposed inside the housing 1, and a plug 2 disposed on the right side of the housing 1 and electrically connected to the PCB. It further includes a conductive wire 3 passing through the lower end face of the housing 1 and electrically connected to the PCB. The extending direction of the conductive wire 3 is perpendicular to the extending direction of the plug 2. A clamping portion 4 is further disposed on the left side face of the housing 1. A vertical fixing groove 51 and a horizontal fixing groove are also provided on the housing 1. The vertical fixing groove 51 includes a vertical groove A501 and a vertical groove B502 oppositely disposed on the front side face and the rear side face of the housing 1. The horizontal fixing groove includes a horizontal groove A521 and a horizontal groove B522 oppositely disposed on the front side face and the rear side face of the housing 1.
[0017] In actual use, when the test head of the present application is not needed for testing, the test head of the present application is placed on a dedicated material receiving mechanism. When the lower end face of the housing 1 is supported by the material receiving mechanism, the buckle of the material receiving mechanism is inserted into the vertical fixing groove 51 to fix the test head of the present application. When it is necessary to take out the test head of the present application from the material receiving mechanism for testing, an external gripper is used to grip the clamping portion 4, and the test head is pulled out from the material receiving mechanism along the extending direction of the vertical fixing groove 51, and then the test head is driven to move horizontally towards the test fixture side. When the left side face of the housing 1 is abutted by the test fixture, the test fixture is inserted into the horizontal groove A521 and the horizontal groove B522 of the horizontal fixing groove to fix the test head in the working state.
[0018] In the above design, as Figure 1 and Figure 2 shown, by respectively disposing the conductive wire 3 and the plug 2 on the lower end face and the right side face of the housing 1, it can be ensured that the conductive wire 3 is always located below the housing 1 during the transfer of the test head. When multiple test heads are placed side by side for transfer, the conductive wires 3 of different test heads will not be entangled; by providing the vertical fixing groove 51, it is convenient to receive the test mechanism vertically and ensure that it is not easy to slide off after receiving; by providing the horizontal fixing groove, it is convenient for the test head to move horizontally for plugging and unplugging tests.
[0019] Specifically: as Figure 1 and Figure 2 shown, the clamping portion 4 includes a disk 41 integrally formed with the left side face of the housing 1, a prism 42 integrally formed at one end with the side of the disk 41 away from the housing 1, and a limiting portion 43 integrally formed with the other end of the prism 42.
[0020] In actual use, an external gripper clamps the prism 42, and the limiting portion 43 and the disk 41 prevent the external gripper from slipping off the prism 42.
[0021] In the above design, the structural design and specific implementation manner of the clamping portion 4 can facilitate the external gripper to grasp and transfer the test head of the present application.
[0022] Specifically: As Figure 1 and Figure 2 shown, the vertical groove A501 includes a strip groove provided on the front side of the housing 1 and a tapered groove communicating with the lower end of the strip groove. The notch of the tapered groove diffuses downward, and the upper opening of the tapered groove is equal in width to and aligned with the strip groove.
[0023] During actual use, the buckle of the external material receiving mechanism passes through the strip groove, passes through the strip groove from the tapered groove, and then produces an undercut with the upper end surface of the housing 1. At the same time, the external material receiving mechanism presses against the lower end surface of the housing 1 through the mounting seat for installing the buckle.
[0024] In the above design, the structural design of the vertical groove A501 facilitates the insertion of the buckle of the external material receiving mechanism into the vertical groove A501, improving the efficiency of material receiving.
[0025] Specifically: As Figure 1 and Figure 2 shown, the plug 2 includes a metal conductive head 21 passing through the housing 1 and electrically connected to the PCB, and an injection molded outer shell 22 provided outside the metal conductive head 21. The injection molded outer shell 22 is injection molded with the housing 1, and a chamfer 201 is provided on the side of the injection molded outer shell 22 away from the housing 1.
[0026] During actual use, through the guiding of the chamfer 201, the plug 2 is inserted into the external test interface.
[0027] In the above design, the structural design and specific implementation method of the plug 2 can facilitate the quick insertion of the plug 2 into the external connector.
[0028] Specifically: As Figure 1 shown, the conductive wire 3 includes a core wire passing through the housing 1 and electrically connected to the PCB, and an injection molded outer skin covering the outside of the core wire. A reinforced injection molded part 301 is provided between the injection molded outer skin and the housing 1.
[0029] In the above design, by providing the reinforced injection molded part 301, the connection between the injection molded outer skin and the housing 1 can be effectively made firm.
