Description

A circuit board mounting connector

The present invention relates to a circuit board mounting connector, and more particularly to a connector for mounting a circuit board, in which a guide groove having a guide surface formed in a shape similar to that of a lower portion of a connection pin is formed in a terminal block so that the connection pin can be easily engaged To a circuit board mounting connector.

The integration degree of the circuit board is increased in accordance with the trend of high function and miniaturization of various electronic products and it is required to improve the connector for electrically connecting the main functional parts inside and outside the circuit board. For example, zero insertion force (ZIF) connectors, which are applied to wafer inspection equipment, UMPC, netbooks, and other products equipped with flexible circuit boards, can be connected in a small space, but exhibit weak electrical connection and mechanical compatibility.

As a result, there has been an attempt to complement the weaknesses of the ZIF connector in the industry.

As an example of the prior patent, a connector device for electrically connecting electrical and electronic components according to "connector device" of Korean Patent Registration No. 10-07817, comprising: a printed circuit board having a plurality of ground electrodes; An electrical component in which a plurality of signal terminals are formed; An interposer formed between the printed circuit board and the electric component and electrically connecting the ground electrode and the signal terminal; A pressing member for pressing the electric component to come into contact with the interposer; And a driving member for driving the pressing member.

This minimizes the signal path and improves the electrical characteristics. It is possible to cope with the narrow pitch. It is expected to increase the convenience of connection and to cope with the low cost. However, due to the structural characteristics mediating the interposer, the reliability and durability Can be seen.

As another example of the prior patent, Korean Patent Registration No. 10-89789 discloses a connector having a housing and a connecting pin, wherein the connecting pin is formed of a signal terminal for transmitting a signal and a ground terminal for forming a contact, And the connecting pin is formed as a single member, and a bending portion bent to surround the connecting pin of the mating connector is formed, the lower side of the connecting pin is first bent to have elasticity, So as to have a bending surface.

This is advantageous in that it is easy to mold the housing and the connection pin, so that it is advantageous in automation, the grounding is stabilized, the signal transmission rate is increased, and the close fixing force to the substrate is increased. However, since the rivet is pressurized and joined by frictional force, it is difficult to maintain a high fixing force, so that the applicability to various products can be limited.

When the connecting pin is coupled to the housing, a certain force is externally applied to the connecting pin to push the connecting pin from the lower side of the housing toward the upper side. In this case, the connecting pin is bent or hits the edge of the housing There is a problem that the connector can be brought into a defective state due to damage of the connecting pin such as the teeth.
