[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0037] The multi-head connector of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0038] Reference Figures 1 to 3As shown, the multi-head connector provided in this embodiment of the present invention includes: at least three adapter plugs 10 and a flexible circuit board 20. The at least three adapter plugs 10 are at a 90° angle to each other along their respective axes. The input ends of the multiple adapter plugs 10 together form an installation space 101. The outer dimensions of the installation space 101 are approximately equal to the radial dimensions of the adapter plugs 10. The closed ends of the three adapter plugs 10 can be closed by a T-shaped housing 30, so the outer dimensions of the installation space 101 can be the inner dimensions of the T-shaped housing 30. The plug ends of the three adapter plugs 10 can be plugged into cables, etc. Each adapter plug 10 has multiple connecting pins 102 for electrical connection. The flexible circuit board 20 is disposed in the installation space 101. The flexible circuit board 20 includes at least three connecting segments and a bending segment. Each connecting segment is connected to the connecting pin 102 on each adapter plug 10, and the bending segment is connected between the connecting segments.

[0039] Preferably, the multi-adapter connector in this embodiment is a T-type connector, including three adapter plugs 10: a first adapter plug 11 and a second adapter plug 12, which are coaxially arranged along a first axis and facing opposite directions, and a third adapter plug 13, which is coaxially arranged along a second axis. The first axis and the second axis are perpendicular to each other. The three adapter plugs 10 can form a T-shaped structure. The included angle between the first adapter plug 11 and the third adapter plug 13 is 90 degrees, and the included angle between the second adapter plug 12 and the third adapter plug 13 is also 90 degrees. The spacing between the first adapter plug 11, the second adapter plug 12, and the third adapter plug 13 can be set to be sufficient to connect and install the flexible circuit board 20, so as to ensure that the flexible circuit board 20 is fixed in the installation space 101 with the installation space 101 as small as possible, thereby reducing the overall volume.

[0040] As an optional embodiment, based on the T-shaped adapter structure described above, it is understood that the included angle between the axes of two adjacent adapter plugs 10 is less than or equal to 180 degrees. Optionally, for example, at least three adapter plugs 10 can also form a Y-shaped structure, in which case the included angle between the first adapter plug 11 and the second adapter plug 12 can be 120 degrees, the included angle between the first adapter plug 11 and the third adapter plug 13 can be 120 degrees, and the included angle between the second adapter plug 12 and the third adapter plug 13 can be 120 degrees. In other embodiments, the included angles between the first adapter plug 11, the second adapter plug 12, and the third adapter plug 13 can be set according to actual needs, and no limitation is made here.

[0041] The peripheral dimensions of the mounting space 101 refer to any one or more of the length, width, and height dimensions of the mounting space 101. It is understood that the phrase "approximately equal to" the peripheral dimensions of the mounting space 101 are "approximately equal to" the radial dimension of the adapter plug 10, which includes certain tolerances. These tolerances, taking into account measurement and tolerances associated with the measurement of a specific quantity, represent acceptable deviations for a specific value as determined by a person skilled in the art, to ensure that the size of the mounting space 101 is as small as possible while still mounting the flexible circuit board 20. For example, "approximately equal to" can mean within one or more standard deviations, or within 3% or 5% of the dimensional value.

[0042] The following situations fall within the scope of "approximately equal to": For example, the outer perimeter of the installation space 101 is greater than or equal to 1%, 2%, or 3% of the radial dimension of the adapter plug 10; for example, the distance between the first adapter plug 11 and the second adapter plug 12 is greater than or equal to the radial dimension of the adapter plug 10; or the outer perimeter of the installation space 101 is less than or equal to 1%, 2%, or 3% of the radial dimension of the adapter plug 10, and the distance between the first adapter plug 11 and the second adapter plug 12 is less than or equal to the radial dimension of the adapter plug 10.

[0043] Reference Figure 4 and Figure 5 As shown, the aforementioned flexible circuit board 20 includes: a circuit board 201 and a flexible connecting plate 202. Each circuit board 201 is configured as a connecting segment and is respectively soldered to an adapter plug 10. The flexible connecting plate 202 is configured as a bent segment and is connected between every two adjacent circuit boards 201 to make at least three circuit boards 201 interconnected. Furthermore, the circuit board 201 has a soldering hole 2011, and the connecting pin 102 passes through the soldering hole 2011 and is soldered to the soldering hole 2011.

[0044] In the embodiments of this application, the circuit board 201 is made of a rigid substrate, such as FR4 fiberglass board, and the flexible connecting plate 202 is supported by a flexible substrate, such as polyimide film. Generally speaking, the flexible connecting plate 202 can be an FPC board (Flexible Printed Circuit). The aforementioned connecting pins 102 can be soldered and fixed to the soldering holes 2011 on the circuit board 201 to ensure a more stable overall electrical connection. It is understood that the adapter plug 10 can be plugged into a cable with a female connector, so that the connecting pins 102 can be plugged and fixed into the holes on the female connector. It is understood that there are multiple soldering holes 2011, and each corresponds to a multiple connecting pins 102, so that each connecting pin 102 can be accurately inserted into the soldering hole 2011 for soldering. In some other optional embodiments, the circuit board 201 and the connecting pins 102 can also be plugged and fixed, but usually a connector is required, which will result in relatively large costs and space requirements.

[0045] Furthermore, corresponding to the multi-head connector, there are two flexible connecting plates 202, which are connected between the three circuit boards 201 to form a "U"-shaped structure. The flexible connecting plates 202 can be connected to the circuit boards 201 through a pressing process, allowing the flexible connecting plates 202 to be positioned at the connection points of the circuit boards 201. When bending is required, simply bending the flexible connecting plates 202 aligns the solder holes 2011 on the circuit boards 201 with the connecting pins 102 for insertion, thus completing the soldering operation. It can be understood that when soldering assembly is required, the flexible connecting plates 202 can be bent first before soldering the solder holes 2011 on the circuit boards 201 to the connecting pins 102, or the connecting pins 102 can be soldered to the solder holes 2011 on the circuit boards 201 first before bending.

[0046] In another embodiment, the flexible connecting plate 202 has at least one component. The at least one flexible connecting plate 202 includes a middle section 2021 and two connecting sections 2022 connected to both ends of the middle section 2021. The middle section 2021 is connected to at least one circuit board 201, and the two connecting sections 2022 are respectively connected to at least two circuit boards 201. The middle section 2021 of the flexible connecting plate 202 can completely cover and press onto the circuit board 201, and the two connecting sections 2022 can either completely press onto and cover the circuit board 201 or be connected to the edge of the circuit board 201. By providing only one flexible connecting plate 202, the processing technology of the bendable circuit board 20 can be simplified.

[0047] Specifically, each adapter plug 10 includes: a plug body 103 and a locking part 104. Multiple connecting pins 102 are disposed on the plug body 103 and are soldered together to the circuit board 201. The locking part 104 is sleeved on the plug body 103 and is rotatable about the axial direction of the plug body 103. The locking part 104 can be a threaded structure, allowing the plug body 103 to engage with the inner cavity of the female connector of the cable. Simultaneously, the locking part 104 can be threadedly fixed to the female connector, ensuring a tight and stable connection between the adapter plug 10 and the female connector.

[0048] In a preferred embodiment, the peripheral dimension of each circuit board 201 is approximately equal to the radial dimension of the plug body 103. The peripheral dimension of the circuit board 201 typically refers to its length and width. The peripheral dimension of the mounting space 101 can be set based on the peripheral dimension of the circuit board 201. Similarly, the phrase "approximately equal to" in the context of the peripheral dimension of each circuit board 201 being approximately equal to the radial dimension of the plug body 103 includes a certain tolerance. This tolerance, considering measurement and the tolerances associated with measuring a specific quantity, indicates an acceptable deviation range for a specific value as determined by a person skilled in the art, to ensure that the size of the mounting space 101 is as small as possible while mounting the flexible circuit board 20. For example, "approximately equal to" can mean within one or more standard deviations, or within 3% or 5% of the dimensional value.

[0049] The following situations fall within the scope of "approximately equal to": For example, the peripheral dimension of each circuit board 201 is greater than 1%, 2%, or 3% of the radial dimension of the plug body 103; or the peripheral dimension of each circuit board 201 is greater than 1%, 2%, or 3% of the radial dimension of the plug body 103.

[0050] Reference Figure 1 and Figure 2 As shown, a three-way housing 30 is fitted between the three adapter plugs 10. The three-way housing 30 connects and fixes the three adapter plugs 10 together and houses the flexible circuit board 20 in the installation space 101.

[0051] In a specific embodiment of this application, the T-shaped housing 30 can clamp the three adapter plugs 10 at their adjacent ends, so that the flexible circuit board 20 and the three adapter plugs 10 can be locked together by the T-shaped housing 30 to form a whole. The T-shaped housing 30 may include two splicing shells, which are fixed by screws or other means. As a preferred embodiment, the T-shaped housing 30 and the adapter plugs 10 should maintain a sealed connection to ensure that the flexible circuit board 20 can be sealed in the installation space 101, preventing moisture from entering and thus improving the overall service life.

[0052] The multi-head connector provided by this utility model connects at least three adapter plugs 10 with their connecting pins 102 via a flexible circuit board 20 located in the installation space 101. Compared with the traditional method of using wire connections, this method saves more internal space. The connection between the adapters can be achieved by inserting the pins into the circuit board. Each adapter plug 10 does not need to bend the connecting pins 102 to achieve the connection, which makes the overall processing efficiency higher, avoids the problems of complex internal wiring and narrow space, improves the stability of the connection structure, ensures transmission quality and connector lifespan, and the flexible circuit board 20 can also better adapt to different spatial layout requirements.
