Description

Contact Sheet and Socket Structure {CONTACT SHEET AND SOCKET}

The present invention relates to a contact sheet, and more particularly, to a contact sheet in contact with an electrical device having an electrode pattern having a predetermined arrangement and electrically connected to the electrical device, wherein the contact sheet has a predetermined area and thickness And a plurality of contact patterns arranged on the sheet body and electrically connected to the electrode patterns of the electric device, wherein the sheet body is made of an insulating material and has a predetermined area, The contact sheet relates to a contact sheet in which the thickness of the outer portion is different from that of the inner portion.

A socket is a member that mediates the connection of a given electrical device and is used with the device to facilitate its connection. These sockets are used in various fields such as testing of various electric parts in addition to ordinary electric parts.

When conducting a test through a connection between such a socket and a given device, it is very important to reliably achieve the connection and contact between the electrical terminal formed between the electrical terminal formed in the socket and the device.

However, as the number of terminals of the device increases and the size increases, warpage occurs, and the flatness of the outer portion and the inner portion are different from each other, so that the height between the terminals becomes different, and the contact may be defective.

For example, FIG. 1 shows a case in which the outer portion of the device D1 is downwardly biased downward. At this time, a failure in connection between the terminals between the socket D2 and the device D1 may occur, There is a high probability that the connection of the terminal located in the terminal is bad. Of course, the opposite is possible, and vice versa, especially if the terminals are located on the outer perimeter.

Accordingly, there is a need to develop a member that reliably achieves the connection between the socket and the device.

Referring to FIG.

A contact sheet 100 according to an embodiment of the present invention is a contact sheet 100 which is in contact with an electrical device having an electrode pattern having a predetermined arrangement and is electrically connected to the electrical structure, A sheet body 110 constituted of a sheet having a predetermined area and thickness and constituted by an insulating material and having a predetermined area; And a plurality of contact patterns (120) arranged on the seat body (110) and electrically connected to electrode patterns of the electric device, wherein the contact sheet (100) .

The contact patterns 120 are pad-shaped members having a predetermined area and thickness, and a plurality of the contact patterns 120 are arranged on the sheet body 110 to occupy an area on the sheet body 110 partially. The contact pattern 120 is made of a material having electric conductivity and flexibility and may include, for example, conductive silicon, nickel, gold, silver, palladium, iron, copper, .

The contact pattern 120 has an arrangement in which at least one portion overlaps with an electrode pattern provided in a predetermined device. That is, each of the contact patterns 120 may be arranged so that at least a portion thereof overlaps with an electrode pattern provided in the device, so as to have an arrangement corresponding to an electrode pattern provided in a predetermined device. Here, the term " overlap " means that when the contact sheet 100 according to the present invention is placed on a predetermined device and viewed from above, the contact pattern 120 provided on the contact sheet 100 and the electrode pattern of the device It can be understood that at least one part overlaps.

The contact sheet 100 according to the present invention has a thickness different from that of the outer portion. In other words, for example, as shown in FIG. 2, the thickness M of the outer portion may be formed thinner than the thickness N of the inner portion. Accordingly, the contact sheet 100 according to the present invention may have a shape having a predetermined inclined surface and a central portion rising in a relatively upward direction. On the other hand, as shown in Fig. 2, it is not necessarily limited to the case where the outermost portion has a pointed attachment, and a region having a partly the same thickness may also be provided.

For example, in the case of a conventional electric device, as shown in FIG. 1, there is a case where the contact between the electrodes provided in the device is not reliably performed as a whole with a uniform height. That is, for example, when electrode connection between a predetermined electric device D1 and the socket structure D2 is performed, warpage occurs as the number of terminals constituting the electrode pattern of the device D1 increases and the size of the device D1 increases. In this case, as shown in FIG. 1, the height of the electrode pattern of the outer portion of the upper portion of the device D1 is set to be low as shown in FIG. 1, so that the interval H between the electrode patterns is uneven. The contact between the electrode patterns of the inner portion is not reliably performed, and therefore contact failure may occur.
