Description

Technical Field

[0001] This utility model belongs to the field of data acquisition terminal technology, specifically, it relates to a data acquisition terminal for mobile machinery. Background Technology

[0002] Data acquisition terminals for mobile machinery are used for data collection, reporting, local storage, and encryption. Current vehicle-mounted terminal circuit board installation methods are relatively simple, primarily relying on the sealing of the casing and top cover to secure the circuit board. However, this installation method has significant shortcomings, especially in terms of waterproofing and circuit board stability. Simple sealing methods often fail to effectively prevent moisture and humidity from penetrating the circuit board area. Once the circuit board is exposed to moisture, it can not only lead to short circuits and performance degradation but also potentially cause serious safety issues.

[0003] Furthermore, the current installation method may cause the circuit board to vibrate during vehicle operation. This vibration not only affects the normal operation of the circuit board but may also accelerate its aging process and shorten its lifespan. Therefore, improvements are necessary.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] One embodiment of this application provides a data acquisition terminal for mobile machinery, such as... Figures 1-6 As shown, it includes: a housing 1 with an opening at one end, the housing 1 having a receiving space 11, and the opening of the housing 1 communicating with the receiving space 11;

[0031] The cover 2 is connected to the open end of the shell 1 and covers the receiving space 11 of the shell 1.

[0032] Circuit board 3 is connected to the receiving space 11 and is fitted with cover 2; circuit board 3 is located within the receiving space 11.

[0033] A connecting harness 4 is connected to the cover 2. One end of the connecting harness 4 is electrically connected to the circuit board 3, and the other end of the connecting harness 4 extends to the outside of the cover 2. It should be noted that the structure and working principle of the circuit board 3 and the connecting harness 4 are existing technologies and will not be described in detail here. The focus of this embodiment is on how to install the circuit board 3 and the connecting harness 4.

[0034] Specifically, such as Figures 4-5 As shown, in this embodiment, the left and right sides of the accommodating space 11 of the housing 1 are respectively formed with first limiting slots 12. When the circuit board 3 is placed in the accommodating space 11, the left and right sides of the circuit board 3 are respectively adapted to the corresponding first limiting slots 12.

[0035] The inner side of the cover 2 forms a second limiting groove 21. When the cover 2 is connected to the open end of the housing 1, the outer end of the circuit board 3 is adapted to the second limiting groove 21. The circuit board 3 is limited by the first limiting groove 12 and the second limiting groove 21, so that the circuit board 3 is relatively fixed in the accommodating space 11, thereby improving the stability of the circuit board 3.

[0036] Furthermore, in this embodiment, as Figure 6 As shown, a sealing ring is provided on the inner side of the cover 2. The sealing ring is located between the ends of the cover 2 and the shell 1 to increase the waterproof performance between the two. A ring groove 22 is formed on the inner side of the cover 2, and the sealing ring is located in the ring groove 22. The ring groove 22 is located outside the second limiting groove 21.

[0037] Furthermore, in this embodiment, the cover 2 is provided with a wire harness mounting slot 23, which is located inside the groove 22; the connecting wire harness 4 passes through the wire harness mounting slot 23, and in order to increase the waterproofness of the accommodating space 11, the connecting wire harness 4 and the cover 2 are integrally injection molded.

[0038] Furthermore, in this embodiment, as Figures 4-6 As shown, the cover 2 has an indicator light clearance slot 24, and the indicator light clearance slot 24 has one or more indicator light clearance holes 25. The indicator light clearance holes 25 are used to accommodate the installation of indicator lights on the circuit board 3. A transparent lens 26 is connected to the opening of the indicator light clearance slot 24 to facilitate observation of the indicator light status. Baffles 27 are formed on the inner two sides of the indicator light clearance holes 25 to block the light of the indicator lights and prevent light leakage between multiple indicator lights, which would affect the effect.

[0039] To increase water resistance, the transparent lens 26 is integrally injection molded with the cover 2.

[0040] Furthermore, in this embodiment, as Figure 4 As shown, first fastening holes 13 are formed on the left and right sides of the housing 1 near the opening end of the housing 1; second connecting holes 28 that cooperate with the first fastening holes 13 are provided on the left and right ends of the cover 2. When the cover 2 is connected to the housing 1, the second connecting holes 28 and the corresponding first fastening holes 13 are connected by fastening screws.

[0041] Furthermore, in this embodiment, the housing 1 is provided with a second connection hole 14 for easy installation at a preset position, so that the data acquisition terminal can be connected to the preset position.

[0042] As described above, the data acquisition terminal of this application uses the first limiting slot 12 and the second limiting slot 21 to limit the circuit board 3, thereby fixing the circuit board 3 relatively within the accommodating space 11 and improving the stability of the circuit board 3.
