Description

Polygonal connector

The present invention relates to the technical field of a connector, in particular a polygonal connector.

Traditional connectors are composed of a male head and a female socket, and the purpose of electrical connection is achieved through the combination of the male head and the female socket.

Generally, the assembler needs to visually confirm that the male connector is aligned with the female connector to ensure the combination of the male connector and the female connector. However, in the application field of modular display panels, the display panel shields the male connector and the female connector, making it impossible for the assembler to assemble in a visual manner. In particular, the assembler may be a non-professional assembler, which inevitably causes difficulty in assembly. If the assembly is performed in a rough manner, in addition to the possibility of damaging the male connector and the female connector, it may even damage the display panel itself. In addition to the aforementioned problems, if the electrical connector is used on an embedded circuit board, that is, the connector is set on a printed circuit board with an opening, since the connector is only fixed to the opening through the electrical terminal, when the connector is connected, the electrical terminal may be detached from the printed circuit board due to force and squeezing.

In view of this, the present invention proposes a polygonal connector to solve the problems caused by traditional connectors or problems that cannot be solved.

The purpose of the present invention is to provide a polygonal connector that can strengthen the strength of the electrical connection portion disposed on the printed circuit board by means of a reinforcement portion.

The purpose of the present invention is to provide a first electrical connection portion having a first body combined with a first electrical connection portion having a second body and a fourth body based on the above-mentioned polygonal connector to form a connector that can achieve the purpose of floating connection.

The purpose of the present invention is to combine the electrical connection part and the reinforcement part by a coupling member and to combine two electrical connection parts by a coupling member based on the above-mentioned polygonal connector.

To achieve the above-mentioned and other purposes, the present invention provides a polygonal connector capable of connecting a first printed circuit board and a second printed circuit board. The first printed circuit board forms a first opening and the second printed circuit board forms a second opening. The polygonal connector includes a first electrical connection portion, a second electrical connection portion, a reinforcement portion, a plurality of first terminals and a plurality of second terminals. The first electrical connection portion is arranged at the first opening. The first electrical connection portion provides a first body having a plurality of first latch slots, a plurality of first terminal holes and a plurality of first terminal slots. The first body forms a first accommodating space. The first terminal holes connect the first accommodating space with the outer surface of the first body. The first terminal slots are also formed on the outer surface of the first body. The second electrical connection portion is arranged at the second opening. The second electrical connection portion provides a second body having a plurality of second terminal holes and a fourth body having a guide block, a plurality of second terminal slots and a plurality of fourth terminal holes. The second body forms a second accommodation space for accommodating the fourth body. The fourth body forms a fourth accommodation space for accommodating the guide block. The second terminal holes are arranged corresponding to the fourth terminal holes. The second terminal slots are connected to the fourth terminal holes. The second terminal slots are arranged corresponding to the first terminal slots and the guide block is arranged corresponding to the first accommodation spaces. The reinforcement part is combined with the first electrical connection part. The reinforcement part includes a sheet, a plurality of plugs, a plurality of first extensions and a plurality of first welding parts. The plugs, the first extensions and the first welding parts are connected to the sheet. The first welding parts are connected to the sheet through the first extension so as to be arranged on the first printed circuit board. The plugs are arranged corresponding to the first plug slots. The first terminals pass through the first terminal holes, so that a part of the first terminals is set in the first terminal slots and one end of the first terminals can be connected to the first printed circuit board. The second terminals pass through the second terminal holes and the fourth terminal holes, so that a part of the second terminals is set in the second terminal slots and one end of the second terminals can be connected to the second printed circuit board. After the first electrical connection part is combined with the reinforcement part and the first terminals, the first electrical connection part is fixed to the first printed circuit board through the reinforcement part and the first body is suspended in the first opening, and the first electrical connection part is connected to the second electrical connection part, so that the first terminals are electrically connected to the second terminals.

Compared with traditional connectors, the polygonal connector proposed by the present invention can allow inaccurate alignment connection to easily connect the first printed circuit board to the second printed circuit board during the connection between the first electrical connection part (such as a male connector) and the second electrical connection part (such as a female connector). In addition, it is particularly suitable for embedded circuit boards, that is, the connector is set on a printed circuit board with an opening, which can enhance the strength of the connection between the two connectors, and prevent the connector set at the opening from being pushed by the connection, causing the electrical terminal to be separated from the printed circuit board. The polygonal connector of the present invention can be applied in application fields such as modular display panels and automotive applications.
