Description

Electronic connector

The present invention relates to an electronic connector, which is an electronic connector designed by using a combination of an inner insulating body and a plurality of terminal modules.

As shown in FIG. 1, a typical prior art, such as U.S. Patent No. 8,465,302, the connector is a circuit board (not shown) that is fixed in an electronic device, and the connector belongs to a type The board is vertically stacked on the surface of the board. In Fig. 1, the connector can be a two-layer connector, i.e., the connector can be considered to have two docking jaws but docked with two separate docking connectors (not shown). In the prior art, the connector includes an insulative housing A and four signal terminals B. Each of the signal terminals B has a pair of terminals B1, a connecting portion B2 and a tail end B3. Each of the mating ends B1 is The mating connector can be in mechanical contact with each other, and each of the tail ends B3 is electrically connected to the circuit board, and each of the connecting portions B2 is connected to each of the butting end B1 and the trailing end B3.

In the foregoing drawings, the trailing end B3 of each of the signal terminals B has a through hole B31, and the end B3 of each of the signal terminals B has an elastically deformable capability by using the through holes B31 of the trailing end B3. After the tail end B3 of each of the signal terminals B passes through the circuit board, the circuit board is fastened by the elastic restoring force of each of the tail ends B3, which is commonly referred to as a press-fit terminal. Since the tail end B3 of the fixed terminal must pass through the circuit board, the circuit board A plurality of through holes (not shown) must be fabricated, and the end B3 of each of the terminals B can fasten the board. However, it is disadvantageous to manufacture a plurality of through holes on a circuit board that transmits high frequency electronic signals because the spacing between the through holes limits the spacing between adjacent terminals, and the number of through holes increases the circuit on the circuit board. Difficulties in the layout of the traces, especially if the board has multiple layers of circuit traces. Moreover, since the connector that is commonly used to push the fixed terminal is not soldered to the circuit board, the connector B is not suitable for use because the terminal B3 of the terminal B fastens the holding force formed by the circuit board. The environment of the docking connector can be inserted and removed multiple times.

In the prior art, in order to solve the foregoing problems, a special terminal B end B3 arrangement is designed, but the arrangement is still directed to the pinned fixed terminal, which does not effectively solve the aforementioned problem.

The main purpose of the present invention is to provide an electronic connector, which is an electronic connector designed by using a combination of an inner insulating body and a plurality of terminal modules, so that the connector can be fixed to a circuit board by soldering. The number of through holes on the board is reduced, thereby increasing the convenience of the circuit trace layout on the board.

The second objective of the present invention is to provide an electronic connector, which is an electronic connector designed by using a combination of an inner insulating body and a plurality of terminal modules, so that the connector can reduce impedance discontinuity when transmitting signals. And the design of each of the terminal modules also helps to reduce the variation of the appearance of each of the terminals during the production process.

To achieve the above object, the present invention provides an electronic connector that is fixed to a circuit board. The electronic connector includes an inner insulating body and a plurality of terminal modules. The inner insulating body includes a mating portion and a mounting portion, and the mating portion has at least one mating hole for receiving the pair of connectors Part of it. Each of the terminal modules has a carrier and a plurality of terminals for transmitting electronic signals. The carrier is mounted on the mounting portion, and each of the terminals is formed by a metal thin plate and is commonly fixed to the carrier. Each of the terminals has a pair of connecting portions, a tail end portion, and a main body portion connecting the abutting portion and the tail end portion, each of the abutting portions respectively extending into the mating hole, and each of the main body portions is jointly positioned In the carrier, each of the tail ends extends directly in a direction perpendicular to the surface of the circuit board, such that one surface of each of the tail ends can be attached to the surface of the circuit board, and is not in contact with the surface of the circuit board. One of the ends of the end portion of the terminal is connected to a strip.
