[0021] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0022] like Figure 1-6 As shown, a static load tester with good protection performance includes a front-end unit 1, a host (not shown) wirelessly connected to the front-end unit, and a sensor (not shown) connected to the front-end unit via a connecting cable. The front-end unit includes a housing, a mounting plate 2 is provided on one side of the housing, an interface terminal 3 is provided on the mounting plate, a power socket 4 is provided on one side of the housing, and a terminal protection cover structure for protecting the interface terminal and a socket protection cover structure for protecting the power socket are installed on the housing.

[0023] In this way, during use, the power supply socket of the front-end unit is connected to the power source via power cord 100 to provide power, and the power supply socket is protected by a socket protection structure. Other components are connected to the interface terminals; for example, sensors are connected to the sensor interface terminals via sensor connection lines, communication wires are connected to the communication interface terminals, and positioning antennas are connected to the positioning interface terminals. After connection, the interface terminal and connector positions are protected by a terminal protective cover structure. The terminal and socket protective covers protect the interface terminals and power supply socket, enabling them to withstand harsh testing environments and ensuring a long service life.

[0024] In implementation, the terminal protective cover structure includes an upper cover 5 and a lower cover 6, which are arranged opposite each other. The upper cover and the lower cover have clearance openings opposite the interface terminals. Two brackets 7 are fixedly installed on the housing, with the upper cover and the lower cover located between the two brackets. The brackets have sliding grooves. The lower end of the upper cover and the upper end of the lower cover are respectively fixedly installed with upper sliders 8 and lower sliders 9 for sliding cooperation with the sliding grooves. A spacer 10 is fixedly installed in the middle of the brackets. The upper slider, the spacer, and the lower slider are connected by through holes 11, and bolts 12 pass through the through holes and are connected to nuts.

[0025] In this way, after the interface terminal and connector are connected, the upper and lower covers slide close together and fit against each other, with clearance openings to avoid interference with the interface terminal. Bolts pass through the through holes and are connected to nuts, fixing the upper and lower covers to the outside of the connector 200. This protects the connection between the interface terminal and connector from signal interference caused by deformation due to external impact. The upper and lower sliders slide in conjunction with the bracket, providing a mounting base for the upper and lower covers.

[0026] In practice, an upper magnet is embedded in the upper slider, and a lower magnet is embedded in the bracket directly opposite the upper slider. The upper and lower magnets have opposite polarities and can attract each other. When connecting the connector to the interface terminal, the upper cover is slid, and the position of the upper cover is fixed by the attraction between the upper and lower magnets. After the connector and interface terminal are connected, the upper cover can be manually pushed downwards to separate the upper and lower magnets.

[0027] In implementation, a guide rail 13 protrudes from the inner side of the bracket, and the upper and lower covers are recessed to form guide grooves 14 that slide with the guide rail. This facilitates the guidance of the movement of the upper and lower covers.

[0028] During implementation, sealing gaskets are fixed to the opposing surfaces of the upper and lower covers. The sealing gaskets are rubber gaskets, which can seal the joint, provide waterproofing, and prevent damage to the joint.

[0029] During implementation, handles 15 are fixedly installed on both the upper and lower covers to facilitate movement of the upper and lower covers.

[0030] In implementation, the socket protective cover structure includes an outer frame 16 fixedly mounted on a rack. The outer frame covers the outside of the power socket, and a cover is rotatably mounted on the outer frame. A cable pass-through port 18 is provided at the lower end of the outer frame. The cover is opened, and the power cord plug is connected to the power socket. The power cord wire passes through the cable pass-through port. The cover rotates to the outside of the power cord plug to protect the connection between the power cord and the power socket.

[0031] The front-end unit contains a control chip, and the interface terminals are electrically connected to the control chip, which is existing technology and will not be described in detail here. This application addresses the protection issues existing in the interface terminals and power sockets by designing a solution that improves the overall protection effect and is more conducive to the stability of signal transmission under long-term use.

[0032] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
