Detailed implementation manners
[0026] Now, in conjunction with the drawings, a detailed description of the preferred embodiments of the present invention will be given.
[0027] Refer Figures 1 to 4 , Figure 1 Is a combined perspective view of the base station of the present invention, and the junction box is in a closed state. Figure 2 Is a combined perspective view of the base station of the present invention, and the junction box is in an open state. Figure 3 Is a cross-sectional view of the combination of the radiator and the junction box of the base station of the present invention. Figure 4 Is Figure 3 A partial enlarged view of the area indicated by arrow A in . The present invention takes the main device AAU (Active Antenna Unit, active antenna unit) in 5G access applications as an example, and proposes a base station 100, which includes: a radiator 50 and a junction box 60.
[0028] The radiator 50 includes: a substrate 510, a plurality of fins 520 vertically extending from the back surface of the substrate 510, an end baffle 530 vertically extending from the end of the front surface of the substrate 510, and a support leg 540 extending downward from the lower end baffle 530.
[0029] The junction box 60 is installed on the lower end baffle 530 and extends downward. It can be understood that the support legs 540 arranged on both sides of the junction box 60 are beneficial to protecting the junction box 60 from the destructive influence of unnecessary external impacts.
[0030] The junction box 60 includes: a base 610, an upper cover 620, a pivot combination 670 for pivotally connecting the upper cover 620 and the base 610 together, and a latch 680 for fastening the upper cover 620 and the base 610 together in a closed state. The base 610 is installed on the end baffle 530 of the radiator 50. For example, the base 610 and the end baffle 530 are welded together, and the end baffle 530 and the substrate 510 are welded together.
[0031] In some embodiments, the rear wall of the base 610 and the end baffle 530 can be reused, that is, the base 610 borrows the end baffle 530 as the rear wall, and the end baffle 530 is provided with an opening at a position corresponding to the receiving cavity of the base 610 for connecting the receiving cavity of the base 610 with the main receiving cavity of the base station 100.
[0032] In other embodiments, the base 610 is provided with a rear wall independent of the end baffle 530, and the rear wall and the end baffle 530 are provided with openings at positions corresponding to the receiving cavity of the base 610 for connecting the receiving cavity of the base 610 with the main receiving cavity of the base station 100.
[0033] See Figure 5 , Figure 5 , which is a perspective view of the base and the pivot combination in the junction box of the base station of the present invention. The base 610 is provided with a receiving groove 611 and a receiving cavity 612. The base 610 is also provided with an opening 613 at the position where the receiving cavity 612 is located.
[0034] See Figure 6 , Figure 6 , which is a perspective view of the base seal in the junction box of the base station of the present invention. The base seal 630 is provided with a first sealing strip 631, two first sealing seats 632 and two plugs 633. The first sealing strip 631 is divided into two parts. The first part is generally C-shaped and is connected to the outside of the two first sealing seats 632, and the second part is in a shape of a straight line and is connected to the inside of the two first sealing seats 632. The first sealing seat 632 is provided with an opening (corresponding to the opening 613). When the base seal 630 is installed in the base 610, the first sealing strip 631 is correspondingly received in the receiving groove 611, and the first sealing seat 632 is correspondingly received in the receiving cavity 612. The plug 633 is received inside the junction box 60 when the base station 100 has no connection with external devices, for example: in the factory state, and is used to be inserted into the opening on the first sealing seat 632 from the inside to the outside to block the opening, so as to prevent external moisture and dust from entering the inside of the junction box 60 through the opening.
[0035] See Figure 7 , Figure 7 which is a perspective view of the upper cover of the junction box of the base station of the present invention. The upper cover 620 is provided with a pointed convex rib 621, a receiving cavity 622 and a receiving groove 624. Specifically, the extending contour of the pointed convex rib 621 corresponds to the first part of the aforementioned first sealing strip 631, that is, the extending contour of the pointed convex rib 621 is generally C-shaped. The pointed convex rib 621 has a cross-sectional structure that is narrow at the top and wide at the bottom, which is beneficial for embedding into the first sealing strip 631. In this embodiment, the cross-section of the pointed convex rib 621 is an isosceles triangle with a flattened top, that is, the cross-section of the pointed convex rib 621 is a trapezoid with a shorter upper side. Avoidance grooves 6212 are provided on both sides of the pointed convex rib 621 (in other embodiments, the avoidance groove 6212 can be provided only on one side of the pointed convex rib 621). Two end heads 6215 of the pointed convex rib 621 are correspondingly arranged at the joint of the pointed convex rib 621 and the receiving cavity 622. End head avoidance grooves 6216 are provided on both sides of the end head 6215 of the pointed convex rib. The end head 6215 of the pointed convex rib forms a stop for the avoidance groove 6212, that is, the end head 6215 is the end of the avoidance groove 6212. The receiving groove 624 is connected between the two receiving cavities 622.
[0036] See Figure 8 , Figure 8 which is a perspective view of the combination of the upper cover and the upper cover seal of the junction box of the base station of the present invention. The upper cover seal 640 is provided with two second seal seats 642, a second sealing strip 644 connected between the two second seal seats 642, and two end head lugs 645 respectively arranged on one side of the two second seal seats 642 away from the second sealing strip 644. An opening is provided on the second seal seat 642, which corresponds to the opening on the aforementioned first seal seat 632. When the upper cover seal 640 is installed in the upper cover 620, the second seal seat 642 is correspondingly received in the receiving cavity 622. The second sealing strip 644 is correspondingly received in the receiving groove 624. The two end head lugs 645 correspondingly cover the two end heads 6215. The cross-sectional structure of the end head lug 645 corresponds to the cross-sectional structure of the end head 6215. In this embodiment, the end head lug 645 is in an inverted V shape.
[0037] Please refer back to Figure 4, when the junction box 60 is in the closed state and fastened together by the latch 680, on the left side of the drawing, the relatively hard pointed convex rib 621 on the upper cover 620 (for example: made of metal; similarly, the base 620 can be made of metal) correspondingly embeds into the first sealing strip 631 of the relatively soft base seal 630 (for example: made of silicone; similarly, the upper cover seal 640 can be made of silicone). The deformation generated by the extrusion of the first sealing strip 631 will correspondingly fill into the avoidance groove 6212. At the same time, on the right side of the drawing, the end 6215 on the upper cover 620 together with the end lug 645 covering the end 6215 correspondingly embeds into the first sealing strip 631 of the base seal 630 (at this time, the end lug 645 correspondingly embeds into the end avoidance groove 6311 part of the sealing strip 631), that is, the end 6215 of the pointed convex rib 621 tightly abuts against the first sealing strip 631 via the end lug 645 on the upper cover seal 640. The deformation generated by the extrusion of the end lug 645 will correspondingly fill into the end avoidance groove 6311.
[0038] It can be understood that, first of all, by means of the embedding and extrusion effect of the relatively hard pointed convex rib 621 on the relatively soft first sealing strip 631, a good sealing fit can be formed between the upper cover 620 and the base 610 at the stitching part provided with the pointed convex rib 621 and the first sealing strip 631.
[0039] Secondly, by means of the embedding and extrusion effect of the end 6215 of the pointed convex rib and the end lug 645 on the first sealing strip 631 at the connection with the first sealing seat 632, a good sealing fit can be formed at this joint part.
[0040] Furthermore, by means of the second sealing seat 642 corresponding to the first sealing seat 632, the two can cooperate to well embrace the connection cables correspondingly inserted at the openings 613 and 623, so that a good sealing fit can be formed between the junction box 60 and the cables (not shown in the figure) inserted thereon.
[0041] In addition, by means of the plug 633 usually housed in the junction box 60 to block the openings 613 and 623 where no cables are inserted temporarily, the connection openings not put into use temporarily can be well closed.
[0042] The beneficial effects of the present invention are as follows. Through the ingenious cooperation between the relatively hard pointed ridges 621 on the upper cover 620 and the relatively soft sealing strips 631 on the base seal 630 installed on the base 610, it can ensure that the junction box 60 is in a very good sealing fit. Further, corresponding to the parts beside the openings 613 and 623, through the ingenious cooperation between the end 6215 of the pointed ridge 621 of the upper cover 620, the end lug 645 on the upper cover seal 640 and the first sealing strip 631 on the base seal 630, the sealing fit of the junction box 60 at these joint parts can be strengthened.
[0043] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. For those skilled in the art, the technical solutions recorded in the above embodiments can be modified, or some of the technical features can be equivalently replaced; and these modifications and replacements should all fall within the protection scope of the appended claims of the present invention.
