Board to board connector

This creation is about a connector, especially a board-to-board connector that conforms to the USB Type-C interface specification.

Due to the newly developed USB Type-C connector, it has the advantages of the smallest interface size, the fastest transmission speed, the ability to be positively inserted and reverse inserted, and the backward compatibility and high applicability. Therefore, the USB Type-C connector has been gradually adopted. Nowadays, various 3C electronic products are used. In addition, in the case of a large-screen smart phone, when the above USB Type-C connector is applied, not only the overall height/volume will be increased, but also the actual size of the existing mobile phone will not be designed. Into the bigger screen. Therefore, how to achieve the application of the USB Type-C connector and achieve a larger screen or compact function under the design of the existing large-screen mobile phone is a major problem that the creator of the present invention wants to solve.

One of the objects of the present invention is to provide a board-to-board connector that reduces the height between the first circuit board and the second circuit board to be suitable for a thin and light electronic device.

To achieve the above object, the present invention provides a board-to-board connector including a first circuit board and a second circuit board. The first circuit board is provided with at least one notch. The second circuit board includes a tongue portion corresponding to the notch, a plurality of guiding portions disposed on the corresponding surfaces of the tongue portion, and a plurality of conductive portions electrically connected to the first circuit board.

The present invention also has the following effects. In one embodiment, the second circuit board is a circuit board conforming to the USB Type-C interface specification, that is, the definition of the tongue portion and each of the guiding portions conforms to the USB Type-C interface specification. And the width of the tongue portion is smaller than the width of the notch so as to be inserted into the mating connector.

When the first circuit board is electrically connected to the second circuit board, each conductive portion of the second circuit board is a conductive terminal, and is attached to the first circuit board, for example, in a DIP or SMT manner. In another embodiment, each conductive portion may also be a conductive pad and attached to the first circuit board in an SMT manner, thereby reducing the height between the two circuit boards, thereby achieving a compact mechanism design or vacating more Institutional design (ME) space.

In another embodiment, a metal housing for the socket portion is further included. The metal casing conforms to the USB Type-C interface specification and has a shell body, at least one elastic piece disposed on the shell body, a positioning convex portion disposed adjacent to the elastic piece, and a positioning piece disposed on two sides of the shell body. Through the positioning pieces of the metal casing, the degree of shaking or vibration of the tongue portion in the notch of the first circuit board can be effectively increased to improve the stability of the plug connector.

Specifically, each of the guiding portions 212 is exposed to the two corresponding surfaces 211 of the tongue portion 21 as a gold finger, and the number is 24. Further, the length of the tongue portion 21 can protrude from the length of the notch 11 or be flush with the notch 11, or even shorter than the length of the notch 11, and is adjusted as needed, and is not limited.

As shown in FIG. 4A, FIG. 4B and FIG. 4C, each conductive portion 22 of the second circuit board 2 can be a DIP (Dual In Line Package) or a surface mount technology (SMT; Surface Mount Technology). The way is attached to the first circuit board 1. In other words, in the DIP process as shown in FIG. 4A, each of the conductive portions 22 is preferably a conductive terminal, and each of the positioning portions 12 is a through hole, so that the conductive terminals are pierced and soldered. In the SMT process as shown in FIG. 4B or FIG. 4C, each of the conductive portions 22 may be a conductive terminal and bent to be soldered to each positioning portion 12 of the first circuit board 1, or each conductive portion 22 is electrically conductive. The pads are soldered to the positioning portions 12 which are the same as the conductive pads, and the conductive portions 22 are horizontally attached to the positioning portions 12 to solder the second circuit board 2 to the first circuit board 1. Therefore, the height/overall volume between the first circuit board 1 and the second circuit board 2 is effectively reduced, thereby freeing up more space for the mechanism design (ME) for use in an electronic device that tends to be thin or thin or used for other purposes.

In addition, the second circuit board 2 further includes a body portion 23 attached to the first circuit board 1, and the body portion 23 is soldered with at least one electronic component 24.

However, in the third embodiment shown in FIG. 7, the electronic device can also be a smart phone 7 or other suitable portable electronic device. The smart phone 7 has an opening 71 for docking with a docking connector (not shown), and the second circuit board 2 is a printed circuit board conforming to the USB Type-C interface specification.

Since the tongue portions 21 of the second circuit board 2 of the first to third embodiments are not mounted with a metal case (not shown), they are directly soldered to a motherboard such as a computer main body or a smart phone (ie, A circuit board 1) can effectively achieve the compact mechanism design or expand the screen size without changing the size of the existing front panel 4 or the smart phone 7.

Please refer to FIG. 8 and FIG. 9 together for a schematic view and a perspective view of a fourth embodiment of the present invention. A specific embodiment with a metal housing 5 can be used without considering the need to free up more space or to achieve a compact structural design. In the present embodiment, a metal casing 5 of the sleeve tongue portion 21 is further included to reduce the probability of the tongue portion 21 swaying and vibrating in the notch 11.

The metal shell 5 conforms to the USB Type-C interface specification and has a shell body 51, at least one elastic piece 52 disposed on the shell body 51, a positioning convex portion 53 disposed adjacent to the elastic piece 52, and one disposed on both sides of the shell body 51. The positioning piece 54 and the two positioning grooves 55 are disposed at the tail end of the shell body 51. When the metal casing 5 is sleeved into the tongue portion 21, a socket 56 for stably plugging the plug (not shown) of the mating connector is formed.

The second circuit board 2 is further provided with two limiting guiding slots 231 opposite to the positioning grooves 55, so that the metal housing 5 can clamp the limiting guiding slots 231 by using the positioning grooves 55 to be fixed to the first circuit board 1 on. The first circuit board 1 is provided with two positioning portions 14 relative to the positioning pieces 54. The positioning portions 14 as shown in FIG. 8 and FIG. 9 are preferably perforated so as to facilitate the penetration of the sheet-like positioning pieces 54. It is placed on each positioning unit 14. However, each of the positioning pieces 54 as shown in FIG. 10 can also be fixedly welded to the positioning portions 14 of the planar pad, and can be changed as needed. Therefore, the degree of sway or vibration of the tongue portion 21 in the notch 11 of the first circuit board 1 can be effectively increased by the positioning pieces 54 of the metal casing 5 to improve the stability of the mating connector 100.

In addition, in the embodiment shown in FIG. 8 to FIG. 10, the elastic piece contact portion (not shown) and the positioning convex portion 53 of each elastic piece 52 are respectively protruded toward the tongue piece portion 21 to increase the mating connector.
