[0005] Insert cards are commonly used in portable PCs, electronic notebooks, mobile phones, fax modems, LAN cards, and the like. The insert card may include, for example, a wireless unit, IC memory, wireless modem or data processing equipment. Insert cards are typically removably interconnected to the electrical equipment that uses the card, so that they can be inserted when needed and removed when not needed.

[0006] Known solutions to EM shielding in insert cards include various types of shielding gaskets, for example, polymers mixed with conductive particles or (often referred to as "Sticky Fingers").
A metal strip having small projections is used. Gaskets for EM shielding are typically expensive to purchase and assemble into insert cards.
In addition, because the gasket requires compression to function, the insert card cover tends to bend.

Another known solution is to use a shielding can (metal hood) that encapsulates the components and grounds the electromagnetic interference. The shield can limits the height of the part.

Another known solution is to use a conductive adhesive in combination with a shielding gasket or conductive frame. This is costly and complicates assembly.

[0029] EMC (Electromagnetic Compatibility) is a combination of two properties of electrical devices: radiation and susceptibility. Radiation refers to unnecessary electromagnetic energy generated and emitted by electrical devices. The radiation is often called RFI (radio frequency interference) or EMI (electromagnetic interference). Interference susceptibility refers to the level of immunity of electrical devices operating in EMI (both conducted and radiated) and power line transient environments.
The EMC of the device is given by combining these two properties. EM
C is how much it affects other electrical equipment in its vicinity and how sensitive it is to environmental disturbances.

Many factors can contribute to EMI, such as atmospheric discharge, electromagnetic processes in machines and plants, energy sources, high speed integrated circuits, and various transmitters such as mobile / cellular phones.
Can be a source of

For example, a plurality of electrical components, circuits, by reducing the level of a jammer signal, reducing the susceptibility of jammers at the receiver, or increasing the attenuation of the path in which jammers are transmitted from their source to the receiver. And the device can be electromagnetically compatible.

The electromagnetic shield (EM shielding) reflects and absorbs electromagnetic interference (EMI / RFI),
Alternatively, it can be said that the device includes a conductive or ferromagnetic material that is grounded.

The resilient tongues of the first and second insert cards 200, 400 allow the ground plane of each printed wiring board to be connected to the first and second insert cards of the respective insert card via corresponding ground conductors. The connection to the housing parts constitutes an effective EM shielding arrangement. The elastic spacing tongues of the third and fourth insert cards allow the ground plane of the respective printed wiring board to correspond to the corresponding ground conductor and 1
An effective EM shielding arrangement is constructed by connecting to the first and second housing parts of each insert card via one or two fixed frames. These EM shielding arrangements provide a grounded enclosure (EM-enclosed) in the insert card that completely or partially surrounds the components in one or more board sections on each printed wiring board. (Shielding zone). Both the ground conductor and the fixed frame are examples of conductive components on a printed wiring board.

When the housing is assembled around the printed wiring board of the insert card, the elastic tongue is partially pressed against the respective housing part (so that the first angle 306 is smaller). This means that the separation tongue exerts pressure on the printed wiring board, which ensures galvanic contact between the separation tongue and the ground conductor and / or the fixed frame that the separation tongue contacts. I do.

In order to optimize the electrical contact between the tip of the tongue and the ground conductor, the surface of the ground conductor and / or the tongue can be surface treated, for example by applying Ni, Sn or Cr.

The side-to-side spacing between the tongues of a group of spaced apart tongues surrounding a board section (or EN shielded zone) of a printed wiring board is determined by the frequency at which the particular board section is designed. This means that the side-to-side spacing may be different between different spaced apart tongue groups of the same insert card. For example, the side-to-side distance d between the separated tongues of the first tongue group can be λ1 / 10, and that of the second tongue group can be λ2 / 10. Here, λ1 and λ2 correspond to the wavelengths of the first and second electromagnetic interference signals, respectively.

The elastic separating tongues in a group of tongues having two rows, eg 214, 215, must be arranged so that each other “points” toward each other as shown in FIGS. Not necessarily. A group of tongues in both rows "point" in the same direction
May be. The elastically separated tongues in the group of tongues forming the rectangle, for example 417, 424, need not necessarily be positioned to "point" to the center of the rectangle as shown in FIG. A tongue within a rectangle may "point" in the opposite direction. Corresponding board sections with a group of tongue and ground conductors according to the invention can be arranged in several different shapes, for example in the form of rows, rectangles, squares or circles.

The elastic tongue can also be used to position the printed wiring board in place inside the housing of the insert cards 200, 400 and 500.
This means that elastic tongues can be used in place of frames, screws, rivets, gaskets or similar fastening means used to place circuit boards in insert cards 200, 400 and 500 in place. Means

The printed wiring board in the insert card of the present invention has two sides, one side and / or
Alternatively, components can be included in an intermediate layer inside the printed wiring board.

Labels 201, 202, 401, 402 and 501 adhered to the outer surface of the housing part of FIGS. 2, 4 and 5 to cover the opening, for example, a metal having a conductive adhesive adhered to one side, for example, Can be made from copper or aluminum. It is preferable to use such a label if the opening under the standoff tang is greater than λi / 10 for the target frequency of the EM shielding design.

To keep the first housing part and the second housing part together, locking means are arranged on the surface / inside of the insert cards 200, 400 and 500.
Locking means have been omitted from the figure for simplicity. Locking means of this kind, such as snap locks, glues or welds, are well known in the art.

The elastic tongue is stamped and formed in the same procedure as the housing part. this is,
This means that no additional processing steps are required to fabricate the elastic separating tongue in the housing part.

While the housings of the insert cards 200, 400 and 500 have been described as including two housing parts, the housings may be, for example, a single housing wrapped around an electrical device, or three or more housings. It can also be designed to include components.
