Description
Technical Field
The present invention relates to a connector soldered on a circuit board and used for inserting a mating member, such that the mating member and the circuit board are electrically connected to each other, and more particularly to a connector with multiple terminals, such as a DDR connector.
Background
Connectors are indispensable parts of electronic components, and are used as components for connecting a circuit on a circuit board, particularly in an operating system, such as an operating system of a notebook computer or a desktop computer, many different types of connectors are required to be used as connecting components between the circuit board and the components, so that the components and the circuit board can be electrically connected with each other through the connectors.
Generally, the connector applied to the circuit board is mainly provided with a plurality of terminals for electrical conduction between the circuit board and the component inside the connector, however, when the terminals are arranged inside the connector, the terminals are electrically connected with the circuit board through two ways, one is PIN insertion type, and the other is SMT type.
The PIN-inserting type mounting mode is that jacks with the same number as the terminals are arranged on the circuit board, so that the terminals can be inserted into the jacks and then electrically conducted in a welding mode, and the effect of electrical connection is achieved. In this type of mounting method, after the circuit board is drilled, a metal conductive layer, which is generally a copper layer coated with a tin layer on the outer portion of the copper layer, is formed in the hole, so that when the connector is soldered to the circuit board, the tin layer is heated in a tin furnace, and the tin layer is melted at a high temperature and then welded to each other, thereby achieving an electrical connection effect.
The SMT type mounting method does not need to drill holes in advance on the circuit board, but forms a metal conducting layer on the surface of the circuit board, and then carries out high-temperature welding with the surface of the terminal. This method can simplify the space of the circuit board, but when the connector needs to be provided with a large number of terminals, such as a DDR connector, the requirement for the flatness of the terminals is quite high, and with the DDR connector, there may be hundreds of terminals in the connector, so the flatness between the terminals and the circuit board is a great key to the yield of the connector.

In the present embodiment, the first positioning portion 534 is a concave portion, and the second positioning portion 544 is a convex portion. When the connector 10 of the present invention is assembled, the terminals 40 are firstly assembled in the first base 53 and the second base 54, respectively, so that the contact ends 42 of the terminals 40 are protruded out of the first slot 532 and the second slot 542, and the soldering ends 41 of the terminals 40 are exposed at the bottoms of the first base 53 and the second base 54, and then the first base 53 and the second base 54 are assembled with each other by using the two connecting members 52.
