Memory card connector

Technical field

The present invention relates to a memory card connector. Specifically, it corresponds to the memory card connector that can stop the memory card at a predetermined position when inserting the memory card, or the memory card with the reverse insertion prevention structure to prevent the insertion in the upside down direction. The present invention relates to a connector for a memory card that can prevent reverse folding. Background art

When a memory card is inserted into the memory card connector, the contacts provided on the connector collar and the card pad provided on the memory card are electrically connected. In order to prevent the memory card from being inserted deeply, there was a configuration in which the insertion end of the memory card abuts the protrusion provided on the memory card connector.

In addition, since the card pad and contacts must be properly connected in a memory card, the insertion direction of the memory card is uniquely determined. If the insertion direction is incorrect, the memory card connector contact will be damaged at the insertion end of the memory card during insertion, so the wrong insertion of the memory card must be prevented. Therefore, in order to prevent the memory card from being inserted upside down, there is a configuration in which a protrusion that abuts against the insertion end of the memory card inserted in the reverse direction is provided to prevent erroneous insertion. It was. In general, a memory card connector is used to insert a memory card. The housing includes a housing in which the insertion portion is formed in a concave shape and a contact is provided at one end, and a plate that covers the top surface of the housing and forms a card insertion space between the HQ-shaped portion of the housing.

In such a memory card connector, the protruding portion that comes into contact with the inserted memory card is provided on the housing or on the plate.

When the protrusions are provided on the housing, they are arranged in close proximity to one end of the housing 1001 of the memory card connector 1001, as shown in FIG. Therefore, there is a problem in that the shape of the contact 102 may be limited in order to secure a space for providing a rib serving as a protrusion. In addition, since the housing 10 1 is made of resin, repeated insertion and removal of the memory force leads to wear of the ribs, resulting in problems in durability and strength.

On the other hand, the plate to be engaged with the housing is made of a metal plate, so it is superior to housing in terms of strength. Therefore, some plates use a plate to restrict the insertion position of the memory card.

An example of providing a protrusion on the plate is “card connector” (Japanese Patent Laid-Open No. 2 0 0 4-1 2 7 7 3 1, hereinafter referred to as Conventional Example 2).

Conventional Example 2 includes: (Invention 1) An insulating housing in which a plurality of terminals are mounted in parallel, and a metal shell provided so as to cover at least a part of the insulating housing. In the card connector, the contact piece of the terminal faces the card receiving cavity formed jointly by the card and is engaged with the contact of the card inserted into the card receiving cavity. The metal shell has a cover plate portion facing a surface where the contacts of the card inserted in the card receiving cavity are provided in parallel, and the cover plate portion is cut and raised to have a U-shaped cross section. Incorrect insertion prevention protrusion protrudes into the card receiving cavity so that when the card is inserted into the card receiving cavity, the card contacts enter into the entrance groove formed in the plane provided in parallel. A card connector characterized by 』

As shown in FIGS. 8 and 9, in the conventional example 2, the card receiving cavity 2 0 4 is formed by the insulating housing 2 0 2 and the metal shell 2 0 3 as the plate, as in the conventional example 1, A plurality of terminals 2 0 1 are juxtaposed in the insulating housing 2 0 2 opposite to the card slot 2 4 1 of the receiving cavity 2 0 4. One end of the terminal 20 1 is positioned outside the housing 20 2, and the other end is exposed as a contact piece 2 1 2 in the card receiving cavity 2 0 4.

Further, the metal shell 20 3 is provided with an erroneous insertion prevention protrusion 2 3 5 at the side of the contact piece 2 1 2 in a plan view. As shown in FIG. 9, the mis-insertion preventing projection 2 3 5 is formed in a U shape by cutting and raising a part of the metal shell 20 3. Therefore, the erroneous insertion preventing protrusion 2 3 5 is formed in a cantilever shape.

Reference numeral 2 0 5 denotes a memory card, and a contact 2 5 2 that is in contact with and electrically connected to the contact piece 2 1 2 of the terminal 2 0 1 is provided at one end of the memory card 2 0 5. The memory card 205 has a notch part 500 as a result of notching one of the side parts of the contact 2552 as shown by arrow B.

The erroneous insertion preventing protrusion 2 3 5 provided on the metal shell 2 0 3 is provided at the position of the notch 5 0 0 when the memory card 2 0 5 is inserted into the card receiving cavity 2 0 4. . As a result, when the memory card 2 0 5 is inserted with the left and right sides reversed (with the front and back reversed), the tip of the memory card 2 0 5 comes into contact with the wrong insertion prevention projection 2 3 5, and the memory card 2 0 5 is Protrusion for preventing incorrect insertion 2 3 5 can no longer be inserted.

Conventional example 2 aims to prevent incorrect insertion to prevent insertion of memory card 2 0 5 when the insertion direction of memory card 2 0 5 is wrong. By installing 3 5 so that it is in the proper position to insert the memory card 205, the insertion position of the memory card 205 can be kept appropriate.

However, in Conventional Example 1, the user inserts the memory card MC, and the memory card MC is placed in the memory card connector with the force pad portion MC 1 of the memory card MC in contact with the contacts 102. At this time, the memory card and the rib provided on the housing 10 1 come into contact with each other to define the insertion position of the memory card. However, as described above, the rib provided on the housing is the housing 10 1. Since it is provided in the part A near the contact 10 2, which is densely arranged at one end, there is a problem that it is difficult to secure a space. In order to secure this space, the contact 100 must be formed in a shape that can secure the space, and the shape of the contact 10 2 is limited. Even if ribs are used, since the housing 110 is made of resin, repeated contact with the insertion / removal of the memory card will result in repeated wear and durability of the ribs. In some cases, there was a problem in strength.

In Conventional Example 2, since the metal seal 20 3 which is a plate is made of a metal plate, the strength and the like are better than those of the insulated housing 20 2, but the thickness of the metal shell 20 3 is 0.6. Since the metal shell 20 3 that is a plate is notched and is provided in a cantilevered support state, the misinsertion-preventing projection 2 3 5 is repeatedly supported against the memory card 2 5 Deterioration occurs due to repeated load on the part, and the erroneous insertion prevention protrusions 2 3 5 are damaged. A problem such as that will occur. Of course, it is sufficient to increase the thickness of the metal shell 20 3. However, increasing the thickness of the metal shell 20 3 causes problems such as increased component costs. In the case of providing the wrong insertion preventing projection 2 3 5, the memory card 2 0 5 is brought into contact with the wrong insertion preventing projection 2 3 5 only when it is inserted in the wrong direction. When the memory card 2 0 5 is used to keep the insertion position properly, the memory card 2 0 5 is always in contact with the projection 2 3 5 to prevent erroneous insertion. The problem that the protrusions 2 3 5 are damaged becomes more serious.

Furthermore, since the cut-and-raised protrusion for preventing incorrect insertion 2 3 5 has a small portion in contact with the tip of the memory card, there is a problem that the tip of the memory card is worn or damaged.

In order to increase the mechanical strength of the erroneous insertion prevention protrusion 2 3 5 without increasing the thickness of the metal shell 20 3 or to prevent damage to the tip of the memory card, the erroneous insertion prevention protrusion However, in this case, the surface area of the metal shell 20 3 decreases and the mechanical strength of the metal shell 20 3 itself decreases. Has a point. Disclosure of the invention

Therefore, according to the present invention, as a memory card connector, it is possible to keep the memory insertion position properly or to prevent the memory card from being inserted if it is inserted incorrectly. A housing body and a metal plate provided opposite to each other constitute a main body that forms a card receiving space, one side of the main body is opened to form a card slot entrance, and a memory card is placed on the housing base that faces the card slot entrance. In contact with the card pad In the memory card connector in which a plurality of contacts to be electrically connected to each other are arranged side by side, the metal plate on the housing base side is formed with a protrusion that protrudes part of the metal plate, and the protrusion is on the card slot entrance side. A memory card connector is provided in which the card is inserted into the card receiving space with the card slot notched or the card slot inlet side and the housing base side notched.

Therefore, in the memory card connector, the protruding part is not cut and raised, but only one of the card slot inlet side is notched and protruded, or the card slot inlet side and the housing body side are parallel, for example. A shape is formed by notching and projecting the notch. Therefore, each part other than the card slot entrance side is formed by stamping or the like integrally with the metal plate, or two parts other than the notch are beaten by stamping or molding integrally with the metal plate. Molded. The notched part that is cut out and abuts against the memory card, and therefore bears the load when the memory card abuts.

In addition, as a memory card connector that can prevent erroneous insertion when a memory card is inserted in the opposite direction, a main body that forms a card housing space is configured by a housing body and a metal plate that are provided opposite each other. In the memory card connector, a plurality of contacts that are electrically connected by contacting the card pad portion of the memory card are formed in the housing base opposite to the card inlet. Then, the metal plate on the housing base side is formed with a protrusion that protrudes a part of the metal plate, and the protrusion cuts out the card slot inlet side or the card slot inlet side and the housing base side. The projecting position of the protrusion is on the card receiving space side of the metal plate, and the memory is stored in the card receiving space. And can enter the pad groove formed in mosquito one Dopaddo portion of the memory card when inserted successfully over de, and the card housing space Hememori Providing a connector for a single memory card, where the insertion end of the memory card is in contact with the protrusion before the insertion end of the memory card comes into contact with the contact when the card is inserted incorrectly. To do.

Therefore, in this memory card connector, the protruding portion having the same shape as described above is formed so as to be able to enter the pad groove formed in the pad portion of the memory card. Therefore, when the memory card is inserted in the normal state from the card slot, the protruding part enters the pad groove formed in the pad part, so the memory card is inserted to a predetermined position and contacted. The card pad portion is normally electrically connected. Also, if the memory card is inserted upside down, the pad groove on the card pad will be open on the opposite side of the metal plate, so the protrusion will not enter the pad groove and the memory card will be inserted. Since it touches the tip and prevents insertion beyond the protrusion, insertion in the reverse direction is prevented. Therefore, according to the present invention, one or two of the protrusions projecting from the metal plate are notched and the other part remains integral with the metal plate, so that sufficient mechanical strength can be obtained. Has an effect.

In addition, in Conventional Example 2 in which only one of the metal plate and the metal plate is integrated, if the amount of the cut and raised is increased, the surface area of the metal plate decreases and the mechanical strength of the metal plate decreases. In the invention, even if the number of protrusions is increased, at least both ends of the protrusions are integrated with the metal plate, so that the mechanical strength of the metal plate is not significantly reduced.

In the present invention, since the protrusions do not significantly reduce the mechanical strength of the metal plate, it is possible to provide a plurality of protrusions or large protrusions, which are in contact with the front end of the memory card. Since the area can be wide, only on the tip of the memory card It is also possible to prevent a large force from being applied, and it is possible to prevent damage to the tip of the memory card.

In addition, side edges 22 extending from the both ends of the housing base 21 to the card slot 4 side are provided. Therefore, the memory card MC inserted from the card insertion slot 4 is inserted while being guided by the side edge 22. As shown in Fig. 2, the contact 5 fixed to the housing base 21 is fixed to the housing base 21 and one end extending from the intermediate is positioned outside the memory card connector 1 and connected to the housing base 21. Configure part 5 1. The other end of the contact 5 extending from the middle portion protrudes toward the force inlet 4 side and is positioned in the card housing space 8 of the memory card connector 1 to form a contact portion 52 to form the memory card MC. Card pad part MC 2 is configured to be electrically connectable. The contact portion 52 is bent or bent at the tip, and the bent or bent protrusion of the bent contact portion 52 2 is electrically connected to the card pad portion MC 2 with contact pressure. The connection is made with a spring force so that the connection can be maintained well.

6 is a half-lock engaging part. The half-lock engaging portion 6 is provided on one side edge portion 22 of the housing body 2. The one side edge portion 22 is a side edge portion 2 2 on the side facing the half lock groove portion MC 3 provided in the memory card MC inserted into the memory card connector 1. The half-lock locking portion 6 is bent in a protruding shape so that the middle portion is V-shaped. The base end portion 62 is locked and fixed to the side edge portion 22, and the other end serving as the tip forms the swing end 63. The half-lock latching portion 6 can be pivoted with the base end 61 as the center of swing, and when the latching projection 61 is pressed by the memory card MC, the half-lock latching portion 6 is pivoted. The urging force by the spring force is always applied.

In this embodiment, the half-lock engaging portion 6 is formed by integrally folding the metal plate 3 with the metal plate 3 by bending a part of the metal plate 3 from the bent portion 31. When stopping, it engages with a groove provided in the housing main body 2, and the latched portion serves as a base end portion 61 of the half mouth hook engaging portion 6.

Here, the memory card MC inserted in the memory card connector 1 will be described. The memory card MC is a card in which a card pad part MC2 for electrically connecting and exchanging information with other devices or exchanging signals is exposed on the card surface, such as a memory stick card. Therefore, the structure of the memory card MC will be described with reference to FIG.

The memory card MC has the card pad MC 2 exposed at one end of the card surface MC 1. This card pad portion MC 2 is formed in a concave shape with a step on the entire card surface MC 1 on the insertion side end MC 6 to the memory card connector 1, and a step is further provided on the card pad portion MC 2. A plurality of pad grooves MC 7 are formed in a concave shape, and each contact part MC 8 is provided in each pad groove MC 7. The contact portion MC 8 is a terminal that is brought into electrical contact with the contact 4 of the memory card connector 1. A plurality of pad grooves MC 7 are arranged in parallel with the insertion side end MC 6. In addition, one end of the card surface MC 1 facing the side edge 22 when inserted into the memory card connector 1 is A semicircular groove MC 3 continuing to the half lock side surface MC 4 is formed. This groove MC 3 is provided in a semicircular shape in which a half-lock locking portion 6 provided in the memory card connector 1 is locked, and is provided in a position where the half-lock locking portion 6 is locked. The card pad portion MC 2 of C and the contact portion of contact 5 are in contact holding state.

The card pad MC 2 of the memory card MC is formed in a concave shape that is one step lower than the force surface MC 1 and the pad groove MC 2 is further lowered by one step from the shape. 7 is formed, but as shown in Fig. 3 (b), the entire card pad part MC2 is formed without a step with the card surface MC1, and the pad groove MC7 is one step from the card surface MC1. Some of them are shaped like ffl.

Next, the erroneous insertion preventing protrusion 7 provided on the metal plate 3 of the memory card connector 1 will be described.

As shown in FIGS. 1 and 4, the erroneous insertion prevention protrusion 7 is located on the housing base 21 side of the memory card connector 1 and on the card slot 4 side from the contact 5 provided on the housing base 21. Located and projecting to the card storage space 8 side. Specifically, the mis-insertion prevention protruding portion 7 is formed in a beat shape from the metal plate 3 to the card receiving space 8 side by the notched portion 7 1 in which the metal plate 3 is aligned in parallel with the memory card MC insertion direction and cut out in two places. Both ends in the width direction of the memory card MC are supported by support parts 72 connected integrally with the metal plate 3, and the beat part 73 is connected to the surface of the metal plate 3 on the card receiving space 8 side. Projected in parallel. The erroneous insertion preventing protrusion 7 is formed by embossing at the same time as pressing the metal plate 3.

With the memory card connector 1 configured as described above, when the memory card MC is inserted in the normal direction from the card slot 4, the slot MC on the insertion side of the memory card MC is eventually inserted. 6 approaches the nosing base 2 1 with the insertion. Then, the contact 5 is pressed and brought into contact with the card pad MC 2 of the memory card MC. At this time, as shown in FIG. 5 (a), the mis-insertion prevention protrusion 7 is positioned on the side facing the metal plate 3 where the card pad portion MC 2 that is recessed in a quadrilateral shape from the surface MC 1 of the memory card MC Therefore, the memory card MC can be inserted without touching the card pad MC 2.

On the other hand, as shown in FIG. 5 (b), when the memory card MC is inserted upside down, the card pad MC 2 provided on the insertion side end MC 6 of the memory card MC is connected to the metal plate 3. Therefore, the mis-insertion preventing projection 7 comes into contact with the leading end of the insertion side end MC 6 of the memory card MC while the memory card MC is being inserted. As a result, the memory card MC is stopped with its insertion being restricted before reaching the contact 5, so that the contact 5 is not damaged by the insertion side end MC 6 of the memory card MC.

In this embodiment, as shown in FIG. 1 and the like, the width of the misinsertion preventing projection 7 is relatively narrow, but the misinsertion preventing projection 7 is formed in a beat shape supported at both ends. Since the mechanical strength is hardly lowered, it may be provided wide across the width of the card pad MC 2 in the width direction of the memory card MC. In this case, when the memory card is erroneously inserted, the erroneous insertion prevention protrusion 7 contacts the insertion side end MC 6 of the memory card MC over a wide range, so that safety against damage to the memory card MC is improved.

In Example 1, as shown in FIG. 3 (a), the memory card MC has a card pad portion MC2 provided in a concave shape that is recessed by one step from the surface MC1, and is further provided in a concave shape that is further recessed by one step. However, depending on the memory card MC, as shown in Fig. 3 (b), the card pad MC 2 is on the same surface as the card surface MC 1, In some cases, the pad groove MC 7 is formed in a recessed shape.

In order to support such a memory card MC, the mis-insertion preventing projection 7 is formed with a width that can enter the pad groove MC 7 and is projected so as not to contact the contact portion. To do. Then, the erroneous insertion preventing projection 7 is provided at a position facing the pad groove MC 7 of the inserted memory card MC.

Therefore, when the memory card MC is normally inserted, the mis-insertion preventing projection 7 enters the pad groove MC 7, so that the memory card MC can be inserted to the normal insertion position, and the contact part MC 8 between the contact 5 and the pad groove MC 7 Contact with each other to make an electrical connection.

On the other hand, if the memory card MC is inserted in the wrong direction, the wrong insertion prevention protrusion 7 will contact the insertion side end MC 6 of the memory car KM C, and it will be above the contact position. The memory card MC cannot be inserted.

In the above embodiment, the erroneous insertion prevention protrusion 7 is provided by the force insertion prevention protrusion 7 provided so that the memory card MC does not contact the contact 5 and damage the contact 5 when the memory card MC is erroneously inserted. It may be used for positioning to specify the innermost part of the memory card MC when it is inserted normally.

In this case, when the memory card MC is inserted to the innermost part, the erroneous insertion preventing projection 7 is formed at the step MC 9 between the force pad portion MC 2 and the card surface MC 1 shown in FIG. Provide in the contact position. As a result, when the memory card MC is in contact with the erroneous insertion preventing projection 7 and inserted into a position where it cannot be inserted any more, the memory card MC is automatically inserted into the predetermined position at the innermost part. By doing so, normal insertion can be completed at a position where the insertion end of the memory card MC does not contact the housing base 21 of the memory force connector 1.

In each of the above embodiments, the erroneous insertion prevention protrusion 7 is provided only at one location. Since the starting portion 7 is formed in a beating shape that is supported at both ends, the mechanical strength of the metal plate 3 is hardly lowered, so it can be provided at a plurality of locations.

Further, in each of the above embodiments, the erroneous insertion preventing projection 7 is provided in a beat shape supported at both ends, but as shown in FIG. 6, the notched portion 7 is provided only on the card slot 4 side of the erroneous insertion preventing projection 7. 1 may be provided so as to protrude in a hemispherical shape. Industrial applicability

The memory card connector configured as described above can be used for electronic devices such as computers and mobile phones.
