Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0029] As mentioned in the background art, existing communication sticks generally include structures such as a housing and a circuit board. The circuit board is usually installed longitudinally inserted into the housing. However, due to the relatively deep internal space of the housing, it is difficult for the circuit board to be quickly installed in place in the housing without reliable fixing and guiding, thus wasting working hours. For this reason, the inventor of the present application has designed a new type of communication stick, which can solve the problem that the circuit board in the existing communication stick is difficult to be quickly installed in place. The communication stick of the present application will be introduced in detail below with reference to the accompanying drawings.

[0030] It should be noted that the "thickness direction of the guide plate" in the present application is the direction indicated by the letter X in the attached Figure 3 drawing.

[0031] Referring to Figures 1 to 5 as shown, the present application provides a communication stick, which includes a housing assembly 10, a guiding assembly 20, a limiting assembly 30, and a circuit board 40.

[0032] Among them, an installation cavity 101 is provided in the housing assembly 10, and a guiding assembly 20 and a limiting assembly 30 are provided in the installation cavity 101; the circuit board 40 is detachably arranged in the installation cavity 101, and the circuit board 40 can move along the guiding assembly 20 and be fixed in the installation cavity 101 by the limiting assembly 30.

[0033] Since the guiding assembly 20 and the limiting assembly 30 are provided in the installation cavity 101 in this embodiment, when the circuit board 40 needs to be installed on the housing assembly 10, only the circuit board 40 needs to be inserted into the installation cavity 101 along the guiding assembly 20, and then fixed in the installation cavity 101 by the limiting assembly 30, so as to realize the quick and stable installation of the circuit board 40. The structure is simple, and the operation is convenient and fast. Among them, the setting of the guiding assembly 20 provides a guiding space for the insertion of the circuit board 40, and can guide the insertion direction of the entire circuit board 40, so that the circuit board 40 can be inserted in place only once without multiple attempts, saving installation working hours; the setting of the limiting assembly 30 can limit and fix the circuit board 40, effectively ensuring the reliability of the installation of the circuit board 40, and preventing the circuit board 40 from falling off during the use of the communication stick and having an adverse impact on the use effect of the communication stick.

[0034] That is to say, compared with the structure of the communication stick in the prior art, in the present application, by providing a guiding component 20 in the installation cavity 101, the insertion of the circuit board 40 can be guided, so that the circuit board 40 can be inserted in place only once without multiple attempts, saving installation man-hours. And by providing a limiting component 30 in the installation cavity 101, the circuit board 40 inserted into the installation cavity 101 can be limited and fixed, ensuring the reliable installation of the circuit board 40 and preventing the circuit board 40 from falling off during the use of the communication stick and having an adverse impact on the use effect of the communication stick.

[0035] Specifically, the circuit board 40 in the present application includes a printed circuit board (PCB board).

[0036] Further, referring to Figure 3 As shown, the guiding component 20 in this embodiment includes a guiding groove 21, and the guiding groove 21 is arranged on the side wall surface of the installation cavity 101, and the circuit board 40 is slidably arranged in the guiding groove 21. Specifically, the arrangement of the guiding groove 21 can guide the insertion direction of the entire circuit board 40 to guide the circuit board 40 to be better installed and positioned with the housing assembly 10, improving the convenience of installation, and enabling the circuit board 40 to be inserted in place only once without multiple attempts, saving installation man-hours. At the same time, when the circuit board 40 is fixed in the installation cavity 101 by the limiting component 30, the guiding groove 21 can play a further fastening role on the circuit board 40, ensuring the reliable installation of the circuit board 40. It can be understood that when the circuit board 40 needs to be installed on the housing assembly 10, only by inserting the circuit board 40 into the guiding groove 21 and sliding it to the bottom of the guiding groove 21, the circuit board 40 can be installed in place.

[0037] Further, in order to improve the guiding effect of the guiding groove 21 on the circuit board 40, referring to Figure 3As shown in the figure, there are two guiding grooves 21 in this embodiment. The two guiding grooves 21 are respectively arranged on two opposite side wall surfaces of the installation cavity 101, and the limiting component 30 is located between the two guiding grooves 21. Specifically, the arrangement of the two guiding grooves 21 can correct the insertion direction of the circuit board 40, effectively improve the accuracy of the circuit board 40 insertion, avoid repeated insertions, and simplify the assembly process of the circuit board 40. At the same time, in this embodiment, the two guiding grooves 21 are respectively arranged on two opposite side wall surfaces of the installation cavity 101, which can not only guide the insertion of the circuit board 40, further reduce the number of repeated insertions, reduce the installation working hours, but also increase the stability of the circuit board 40 during the sliding process, preventing the circuit board 40 from tilting or swinging. In addition, in this embodiment, the limiting component 30 is arranged between the two guiding grooves 21, which can not only ensure that the circuit board 40 directly contacts the limiting component 30 during the insertion process to achieve the accurate cooperation between the circuit board 40 and the limiting component 30, but also control the position of the circuit board 40 in the guiding groove 21 to prevent the circuit board 40 from being damaged due to excessive sliding.

[0038] Further, referring to Figure 3 As shown in the figure, a chamfer 23 is provided at the notch of the guiding groove 21 in this embodiment. Specifically, the provision of the chamfer 23 facilitates the insertion of the circuit board 40, avoids the guiding groove 21 interfering with the insertion of the circuit board 40, and prevents the circuit board 40 from being worn during the installation or disassembly process, and extends the service life of the circuit board 40 to a certain extent.

[0039] Further, referring to Figure 3As shown in the figure, the guiding component 20 in this embodiment further includes two guiding plates 22. The two guiding plates 22 are respectively arranged against two opposite side walls of the installation cavity 101. Each guiding plate 22 is provided with a guiding groove 21. The guiding groove 21 is recessed from the first side of the guiding plate 22 towards the second side of the guiding plate 22, and the guiding groove 21 penetrates along the thickness direction of the guiding plate 22. Specifically, the arrangement of the guiding plate 22 can provide additional support points for the circuit board 40, further preventing the circuit board 40 from swinging or tilting during the installation process. At the same time, each guiding plate 22 in this embodiment is arranged against the side wall surface of the installation cavity 101, which can effectively disperse the force generated when the circuit board 40 is inserted, thereby improving the stability of the overall structure of the guiding component 20. In addition, since the guiding groove 21 in this embodiment is recessed from the first side of the guiding plate 22 towards the second side of the guiding plate 22 and penetrates along the thickness direction of the guiding plate 22, when the circuit board 40 is inserted into the guiding groove 21, the side edge of the circuit board 40 will contact the side wall surface of the installation cavity 101, so as to ensure that the circuit board 40 directly falls into the guiding groove 21 during the insertion process, and then realize the precise cooperation between the circuit board 40 and the guiding groove 21, without the need to adjust the position of the circuit board 40, and finally realize the rapid and stable installation of the circuit board 40, further reducing the installation man-hours.

[0040] Further, referring to Figures 3 to 5 As shown in the figure, the limiting component 30 in this embodiment includes a limiting buckle 31. A connecting portion 50 is provided on the circuit board 40, and the limiting buckle 31 is buckled to the connecting portion 50 to fix the circuit board 40 in the installation cavity 101. Specifically, the limiting buckle 31 in this embodiment has excellent elasticity. After the circuit board 40 is inserted into the installation cavity 101 under the guiding action of the guiding groove 21, the limiting buckle 31 can be buckled to the connecting portion 50 of the circuit board 40, so as to fix the circuit board 40 in the installation cavity 101 and ensure the reliability of the installation.

[0041] Further, referring to Figures 3 to 4 As shown in the figure, the limiting component 30 in this embodiment further includes a limiting section 32. The limiting section 32 is arranged at an interval from the limiting buckle 31, and there is an installation gap 301 between the limiting section 32 and the limiting buckle 31. At least a part of the connecting portion 50 is located in the installation gap 301. Specifically, the installation gap 301 between the limiting section 32 and the limiting buckle 31 provides an accurate positioning space for the circuit board 40, ensuring that the circuit board 40 can be accurately placed during assembly. At the same time, the limiting section 32 and the limiting buckle 31 provide double support for the installation of the circuit board 40, increasing the stability of the circuit board 40 in the installation cavity 101.

[0042] Optionally, in the present application, the limiting section 32 may include one, two, three or more than three, and the limiting buckle 31 may include one, two, three or more than three. The present application does not make specific limitations here.

[0043] Further, referring to Figure 2 As shown, the housing assembly 10 in this embodiment includes a first housing 11 and a second housing 12 that are connected to each other. The first housing 11 and the second housing 12 enclose an installation cavity 101. The guiding assembly 20 and the limiting assembly 30 are both arranged on the second housing 12 and are located inside the installation cavity 101. Specifically, the arrangement of the first housing 11 and the second housing 12 can prevent the circuit board 40 from being affected by the external environment. At the same time, after the circuit board 40 in this embodiment is fixed on the second housing 12 through the guiding groove 21 and the limiting assembly 30, the circuit board 40 and the second housing 12 are then installed together into the first housing 11 to achieve the rapid and stable installation of the circuit board 40.

[0044] Further, referring to Figures 1 to 2 As shown, one of the first housing 11 and the second housing 12 in this embodiment is provided with a fixing buckle 121, and the other is provided with a card slot 111 adapted to the fixing buckle 121. That is to say, when the fixing buckle 121 is provided on the first housing 11, the card slot 111 is provided on the second housing 12, or when the card slot 111 is provided on the first housing 11, the fixing buckle 121 is provided on the second housing 12. The specific setting situation is not specifically limited in the present application. The attachment in this embodiment Figure 2 shows the situation when the card slot 111 is provided on the first housing 11 and the fixing buckle 121 is provided on the second housing 12. Of course, in other embodiments of the present application, the first housing 11 and the second housing 12 may also be connected by means of screwing or other connection methods. As long as it is other deformation methods under the concept of the present application, they are all within the protection scope of the present application.

[0045] Combined with the above embodiments, it can be known that: the communication stick of the present application includes a housing assembly, a guiding assembly, a limiting assembly and a circuit board. Since the guiding assembly and the limiting assembly are arranged in the installation cavity, when the circuit board needs to be installed on the housing assembly, only the circuit board needs to be inserted into the installation cavity along the guiding assembly and then fixed in the installation cavity through the limiting assembly, so as to achieve the rapid and stable installation of the circuit board, with a simple structure, convenient and fast operation, and effectively avoiding waste of working hours.

[0046] On the other hand, the embodiment of the present application also provides an inverter, which is used to be connected to the above-mentioned communication stick. Therefore, this inverter includes all the technical effects of the above-mentioned communication stick. Since the technical effects of the communication stick have been described in detail above, they will not be elaborated here.
