Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, a board-to-board connector according to an embodiment of the present invention includes an insulating housing 10 for fitting on a PCB, and at least three rows of terminal sets 20 embedded in the housing 10.

Each row of terminal sets 20 includes a plurality of terminals 21 distributed at intervals, a first end of each terminal 21 is exposed out of one side surface of the housing 10, and an opposite second end of each terminal 21 penetrates out of the other side surface of the housing 10.

At least three rows of through hole groups 30 are arranged in the housing 10 corresponding to the terminal group 20, and each row of through hole group 30 comprises a plurality of accommodating holes 31 distributed at intervals; the terminals 21 are fitted into the receiving holes 31 one by one. Each receiving hole 31 penetrates through a side surface of the housing 10, and an opening is formed on the side surface to expose a first end of the terminal 21, thereby facilitating the mating of a mating device (such as a mating connector) with the terminal 21. Each receiving hole 31 penetrates the other side surface of the housing 10, and the second end of the terminal 21 penetrates the side surface to be exposed outside the housing 10 and is used for connecting a PCB.

The side of the housing 10 exposed at the first end of the terminal 21 and the side of the housing 10 through which the second end of the terminal 21 passes may be two opposite sides. The second end of the terminal 21 can be bent and extended after passing through the side of the housing 10 to be able to face the PCB and connect the PCB, which also makes the terminal 21L-shaped.

The housing 10 is made of an insulating material such as plastic. The terminal 21 is accommodated therein by integral injection molding of the housing 10.

In the orientation of the connector shown in fig. 1, the board-to-board connector of the present embodiment includes three rows of terminal sets 20 arranged from top to bottom. Each row of terminal sets 20 includes eight terminals 21 so that the board-to-board connector is a 3 row by 8 column pin connector. Compared with the traditional 2-row 12-column pin connector, the three-row arrangement reduces the arrangement of the column number, so that the length is also reduced, and the length of the whole connector is further reduced.

Further, at least one metal tab 40 for connecting the PCB is provided on a side of the housing 10 facing the PCB. The metal tabs 40 protrude from the side of the housing 10 and can be fixed to the PCB by inserting or welding, thereby fixing the housing 10 to the PCB. The metal lug 40 is made of a metal material, has a certain strength, and is not easily broken by an external force.

Alternatively, the opposite sides of the side of the housing 10 facing the PCB are provided with metal tabs 40, respectively. One or more metal tabs 40 may be provided on each side.

The side of the housing 10 where the terminals 21 are exposed is different from the side of the housing 10 facing the PCB in the housing 10. The side surface of the housing 10 that is engaged with the PCB is used as a bottom surface, and the receiving holes 31 penetrate through two side surfaces of the housing 10 and are opposite to each other and respectively adjacent to the bottom surface. The second end of the terminal 21 extends out of one side of the housing 10, bends relative to the first end and extends in the same direction as the metal soldering lug 40 and faces the bottom surface to connect with the PCB.

In addition, a convex column 11 is arranged on one side surface of the shell 10 facing the PCB. The boss 11 is integrally formed on the side of the housing 10, and is integrally injection-molded therewith. The convex column 11 is used for connecting a PCB, primary positioning of the shell 10 on the PCB can be realized, and the metal soldering lug 40 realizes fastening of the shell 10 on the PCB.

In this embodiment, as shown in fig. 2, the convex pillar 11 is located in the middle of the side surface where the convex pillar is located, and the metal soldering tabs 40 are respectively located at two opposite sides of the convex pillar.

Further, the utility model discloses a board is to line connector still includes back lid 50, and its lid is established and is served and be connected with the cooperation of shell 10 at the second of terminal 21, constitutes integratively and will expose the second end cover of terminal 21 outside with shell 10 and establish wherein, avoids terminal 21 to be stained with debris or dust, ensures the connector life-span.

The second end of the terminal 21 is exposed out of the rear cover 50 toward the open side of the PCB for easy connection to the PCB.

The rear cover 50 is made of an insulating material such as plastic.

The rear cover 50 is butted with a side surface of the housing 10 at one side surface thereof, and the both may be connected by a snap-fit or the like. For example, the back cover 50 has two opposite side walls, each of which has a buckle 51 at the end facing the housing 10; the housing 10 has two opposite side walls, each of which is provided with a fastening slot 52 adapted to the fastening buckle 51. The snap 51 is inserted into the corresponding snap groove 52 when the back cover 50 is mated with the housing 10, so as to connect the back cover 50 and the housing 10. When the cover is detached, the buckle 51 can be separated from the buckle groove 52 by pressing the two opposite side walls of the rear cover 50, and the rear cover 50 can be pulled out from the housing 10.
