[0042] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation method, structure, characteristics and effects of the multi-channel switching device proposed in the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0043] Please refer to 1-5, which is a schematic diagram of the structure of each part of a multi-channel switching device according to an embodiment of the present invention. The switching device includes a switching shell and a switching module 3 fixed in the switching shell. The switching module 3 includes a main body 31, on which a main switching terminal 33 and at least two branch switching terminals 32 with different extension directions are fixed. Each branch switching terminal 31 is connected to a branch transmission link, and each transmission part 31 has the same extension direction as the branch transmission link to which it is connected, and each main switching terminal 33 is connected to a main transmission link. The switching module 3 of the present invention can realize the switching and merging of branch signal links with different extension directions. Through holes are opened at positions corresponding to each branch switching terminal 32 and the main switching terminal 31 on the switching shell to realize the connection between the above-mentioned transmission part and the transmission link.

[0044] In this embodiment, the adapter module 3 is an overall three-way structure, including a main body 31, and the branch adapter terminal 32 and the main adapter terminal 33 are distributed on different sides of the main body 31. Specifically, a main adapter terminal 33 is provided on one surface of the main body 31, and there are two branch adapter terminals 32, which are distributed on two surfaces adjacent to the main adapter terminal 33, thereby realizing a 90-degree adapter and merging of two parallel branch transmission links with opposite transmission directions.

[0045] In this embodiment, the main body 31 and the branch transfer end 32 are integrally formed to form a special-shaped terminal structure, and the branch transfer ends 32 are all crimping barrel structures. The transfer module 3 connects two parallel links respectively through two crimping barrel structures arranged opposite to each other on the main body 31. The total transfer end 33 is a watchband contact finger structure arranged on the end face of the main body 31. The contact finger structure is used as a terminal surface to transmit current with another link, and can realize a 90° transfer of two parallel links within an effective space, that is, a 90° three-way connection. In other embodiments of the present invention, the branch transfer end 32 can also be a jack, a pin or other structure for adapting to the connector contact on the branch transmission link. The structure of each branch transfer end 32 can be the same or can be designed as a different shape structure according to the adapted branch transmission link. The total transfer end 33 can also be a crimping barrel structure or other structure for adapting and plugging with the contact on the adapted transmission link, such as a jack or a pin structure.

[0046] The adapter shell of the present invention has a first cavity 10 extending axially, and both ends of the first cavity 10 are open; the bottom of the adapter shell also extends downward to form a second cavity 21, the upper end of the main body 31 is located in the first cavity 10, and the lower end is located in the second cavity 21, and the two branch adapter ends 32 are both located in the first cavity 10 and distributed on both sides of the second cavity 21, and are used to connect with the branch transmission link entering from the end of the first cavity; the main adapter end 33 extends out of the second cavity 21, and is used to connect with the corresponding transmission link terminal.

[0047] In the embodiment of the present invention, the transfer housing is composed of an upper housing 1 and a lower housing 2, wherein the first cavity 10 is composed of the upper housing 1 and the lower housing 2 buckled together, and the second cavity 21 is located below the bottom of the lower housing 2. In this embodiment, the two transfer terminals 32 are symmetrically distributed on the left and right end surfaces of the main body 31, and are higher than the upper end surface of the main body 31, so that a groove 34 is formed in the middle upper part of the special-shaped terminal structure composed of the main body 31 and the transfer terminals 32. A lower insulator 5 is embedded in the outer periphery of the lower end of the main body 31, and the upper end surface of the lower insulator 5 is stopped and limited by the lower end surface of the branch transfer end 32, and the lower end surface is flush with the lower end surface of the main body 31, so that when the transfer module 3 is assembled in the transfer shell, the lower end surface of the lower insulator 5 is flush with the lower end surface of the second cavity 21. At this time, the axes of the two transfer ends 32 coincide with the first cavity 10, and there is a distance between the two transfer ends 32 and the inner wall of the first cavity 10. When the two transfer ends 32 are connected to the corresponding branch transmission links, glue is poured between the branch transfer ends 32 and the first cavity 10 through the two open ends of the first cavity 10 to form a glue pouring area 7 for achieving sealing between the two.

[0048] In the embodiment of the present invention, an upper insulator 4 is further provided between the special-shaped terminal and the upper shell. The upper insulator 4 is T-shaped as a whole, with its upper end face in contact with the inner wall of the upper shell 1, and its lower end is located in the groove 34. The protruding parts on both sides are pressed on the two adapter ends 32 and connected to the glue in the glue filling area 7.

[0049] In this embodiment, the central axis of the first cavity 10 is consistent with the central line of the supporting transfer end 32 .

[0050] In order to ensure the sealing of the adapter shell, a first sealing strip 8 is further provided between the upper shell 1 and the lower shell 2 of the present invention. Specifically, a groove is provided on the surface where the lower shell 2 and the upper shell 1 are connected, and a protrusion is correspondingly provided on the upper shell 1. The first sealing strip 8 is located in the groove on the lower shell 2 and can cooperate with the protrusion on the upper shell 1 to achieve sealing of the connecting surface of the upper and lower shells. Preferably, the upper shell 1 and the lower shell 2 are fixed after connection by screws 6. In other embodiments of the present invention, the terminal surface between the lower shell 2 and the upper shell 1 is a plane. At this time, the first sealing strip 8 is located in the groove on the terminal surface at the upper end of the upper shell.

[0051] The adapter device of the embodiment of the present invention realizes the termination exchange of the total transmission link through the main adapter terminal 33. In order to ensure the sealing between the adapter device and the total transmission link, the lower shell 2 is provided with a second sealing strip 9 on the lower end face of the second cavity 21. The second sealing strip 9 is embedded in the annular groove distributed around the second cavity 21 on the lower end face of the lower shell 2.

[0052] When assembling the adapter device of the first embodiment of the present invention, first, the lower end of the adapter module 3 is embedded in the lower insulator 5, and then the lower insulator 5 is embedded in the lower shell 2 to achieve the initial positioning of the adapter module in the lower shell 2. Then, the upper insulator 4 is embedded in the corresponding position in the upper shell 1, and finally, the upper shell 1 and the lower shell 2 are buckled and connected by screws. When the assembled adapter device is used, after completing the connection with each transmission link, glue is poured into the glue filling area 7 between the branch adapter end and the adapter shell through the two ends of the first cavity 10, thereby not only achieving the sealing of the connection between the adapter shell and the branch transmission link, but also enhancing the connection strength of the connection.

[0053] See also Figure 6 , which is a schematic diagram of the structure of the adapter module of the adapter device of the second embodiment of the present invention. In this embodiment, the adapter module is provided with three branch adapter terminals 32, which are distributed on the same plane, and two of them are distributed on two opposite surfaces of the main body 31, and the other is located between the two oppositely distributed branch adapter terminals 32, and the main adapter terminal 33 is located on a plane perpendicular to the branch adapter terminals. The embodiment of the present invention can realize the 90-degree switching and merging of the branch transmission links transmitted in three directions, and the three branch adapter terminals 32 are distributed on the same plane, which can effectively reduce the overall height of the adapter device and meet the use requirements of small spaces.

[0054] The adapter housing adapted by the adapter module of this embodiment can also be composed of two parts, upper and lower parts, and the difference between this adapter housing and the adapter housing in the first embodiment is that: a third cavity is formed by extending from one side of the adapter housing, and the third cavity is also surrounded by the upper and lower housings. This embodiment still realizes the positioning of the adapter module in the adapter housing by the cooperation of the lower insulator and the main body, and then the upper and lower housings are buckled together, and the sealing of the adapter position is realized by injecting glue into the first cavity and the second cavity, and the sealing of the housing is realized by the sealing strip at the end joint surface of the upper and lower housings.

[0055] See also Figure 7, which is a schematic diagram of the structure of the adapter module of the adapter device of the third embodiment of the present invention. In this embodiment, the adapter module is provided with four branch adapter terminals 32, which are distributed on four surfaces perpendicular to the main adapter terminal 33, so as to realize the 90-degree switching and merging of four branch transmission links that are transmitted in parallel in different directions. The difference between the adapter module of this embodiment and the second embodiment is that the third cavity and the fourth cavity are respectively formed on both sides of the adapter housing.

[0056] See also Figure 8 , is a schematic diagram of the structure of the adapter module of the adapter device of the fourth embodiment of the present invention. In this embodiment, the adapter module is provided with five branch adapter terminals 32, wherein the five branch adapter terminals 32 are distributed on four surfaces perpendicular to the main adapter terminal 33, and another branch adapter terminal 32 is distributed on the surface opposite to the main adapter terminal, so as to realize the switching and merging of signal links transmitted in five different directions. The adapter housing applicable to the adapter module in this embodiment is different from that in the third embodiment only in that: a fifth housing is formed by extending upward from the top of the upper housing.

[0057] See also Fig. 9 , which is a schematic diagram of an adapter module of an adapter device according to a fifth embodiment of the present invention. The difference between this embodiment and the fourth embodiment is that the five branch adapter ends 32 are all watchband contact finger structures embedded in the main body.

[0058] In other embodiments of the present invention, when the main body 32 is a polyhedron of other structural forms, the branch adapter ends are distributed on various surfaces of the outer periphery of the main body 31, and two or more branch adapter ends 32 can be distributed on the same surface of the main adapter portion 31 to meet different usage requirements.

[0059] In an embodiment of the present invention, the plane where the main transfer end 31 is located is perpendicular or parallel to the plane where the branch transfer end 32 is located. In other embodiments of the present invention, the plane where the main transfer end 31 is located may also intersect with the plane where the branch transfer end is located.
