Description

  The present invention is an insulating body and a press-formed product of a metal plate, comprising a plurality of contacts arranged and fixed to the body at a constant pitch by insert molding, the body having a contact fixing portion, The contact has a fixed portion, and the fixed portion has a plate surface on one side located on the same surface as one surface of the contact fixing portion, and a plate surface on the opposite side located in the resin of the contact fixing portion. Related to the connector. In particular, a connector suitable for reducing the overall thickness by reducing the thickness of the contact fixing portion of the insulating body (for example, a card such as a memory card is an electronic device such as a mobile phone, a digital camera, a portable audio, and a PDA). Card connector for connection to equipment).

Conventionally, there has been a technique for increasing the fixing strength of a contact by providing an embedded portion embedded in the contact fixing portion so that the plate surfaces on both sides are positioned in the contact fixing portion by Z bending or L bending. It was. In Z-bending, for example, as disclosed in Patent Documents 1 and 2, the embedded portion protrudes in the surface direction of the contact fixing portion from a position one step lower than the fixed portion, and in L-bending, for example, as disclosed in Patent Document 3 The portion protrudes from the fixed portion in the thickness direction of the contact fixing portion.
JP 2005-174756 A JP 2006-26169 A JP-A-8-45584

  In the structure in which the buried part is provided by Z-bending in the fixed part, since the resin thickness of the contact fixing part is required on the plate surface side on both sides of the buried part, the thickness of the contact fixing part increases and the thinness is impaired. There was a problem. Further, there is a possibility that the Z-bending portion (embedded portion) of the fixed portion will return and deform (elongate) due to the molding pressure during injection molding (injection pressure of molten resin into the mold). In Z-bending along the width direction of the fixed part as disclosed in Patent Document 1, the length of the fixed part changes (increases), and the length of the contact changes (increases) accordingly. Proper contact timing to the contact object cannot be obtained. In Z-bending along the length direction of the fixed part as disclosed in Patent Document 2, the width of the fixed part changes (increases), so that the insulation distance between adjacent fixed parts becomes small, and the insulation There has been a problem in that it causes poor insulation such as performance degradation and short circuit due to contact.

  In the structure in which the embedded portion is provided in the fixed portion by L-bending, the projecting amount of the embedded portion cannot be sufficiently obtained under the technical problem of reducing the thickness of the contact fixing portion, and effective reinforcement cannot be performed. When the protruding amount of the embedded portion is increased, the thickness of the contact fixing portion is increased, and there is a problem that the thinness is impaired. Further, even if the L-bent portion (embedded portion) of the fixed portion is returned and deformed by the molding pressure at the time of insert molding, the L-bend along the width direction of the fixed portion as disclosed in Patent Document 3 is not covered. The length of the fixed portion changes (increases), and the length of the contact is not changed accordingly. However, in the L-bending along the length direction of the fixed portion, the embedded portion tilts and the fixed portion Since the width changes (increases), there is a problem in that the insulation distance between adjacent fixed parts is reduced, resulting in a poor insulation such as a decrease in insulation performance and a short circuit due to contact.

  In any structure, the embedded portion is provided outside the fixed portion, and the embedded portion has a plate surface that is perpendicular or substantially perpendicular to the flow direction of the molten resin in the mold. There is a problem that it is easily influenced by the above, and it is easy to cause insulation failure and contact timing failure.

  The present invention has been made in view of the above problems, and an object thereof is an insulating body and a press-formed product of a metal plate, and a plurality of contacts arranged and fixed to the body at a constant pitch by insert molding. The body has a contact fixing portion, the contact has a fixed portion, and the fixed portion has a plate surface on one side located on the same plane as one surface of the contact fixing portion, and the opposite side In the connector in which the plate surface is located in the contact fixing portion, it is possible to prevent the contact fixing portion (molded product) from being damaged when increasing the fixing strength of the contact (insert product) and to perform molding at the time of insert molding. It is an object of the present invention to provide a connector in which a contact is not easily deformed even by pressure and does not cause insulation failure even if deformed.

  In order to achieve the above object, an invention according to claim 1 is a press-molded product of an insulating body and a metal plate, and a plurality of contacts arranged and fixed to the body at a constant pitch by insert molding. The body has a contact fixing portion, the contact has a fixed portion, and the fixed portion has a plate surface on one side located on the same plane as one surface of the contact fixing portion, and the opposite side The plate surface is a connector located in the resin of the contact fixing portion, and the fixed portion has a hole portion penetrating from the plate surface on one side to the plate surface on the opposite side.

  In the invention according to the first aspect configured as described above, the resin flows into the hole portion of the fixed portion, and the contact area of the fixed portion to the contact fixing portion increases, so that the fixing strength of the contact increases. In addition, since the increase in the contact area of the fixed part to the contact fixing part is a result of the resin flowing into the hole of the fixed part, it is embedded in the conventional fixed part by Z-bending or L-bending. Unlike the structure in which the portion is provided, the thickness of the contact fixing portion is not impaired. In addition, there is no embedded part that may be deformed by the molding pressure during insert molding, unlike the conventional structure where the fixed part is provided with Z bending or L bending, so the length and width of the fixed part change. This does not cause insulation failure. For this reason, it is not necessary to reduce the molding pressure at the time of insert molding, the molten resin can be surely poured into every corner of the mold, the molding failure is hardly caused, and the productivity is increased.

  A second aspect of the invention is the same as the first aspect of the invention, wherein the portion to be fixed is opposite to a part of a plate surface on one side, which is located on the same plane as one surface of the contact fixing portion, by cutting and raising. A contact portion that has an inclined portion that protrudes obliquely from the plate surface on the side, the hole portion of the cut and raised trace of the inclined portion, and a frame portion that surrounds the hole portion, and the contact fixing portion wraps the inclined portion A configuration having an engaging portion is added.

  With such an additional configuration, a part of the plate surface on one side of the fixed portion that is located on the same surface as the one surface of the contact fixing portion and is exposed on one surface of the contact fixing portion is brought into the contact engaging portion by the inclined portion. Therefore, it is equivalent to the structure in which the buried portion is provided by Z-bending in the conventional fixed portion, and it is possible to improve the contact fixing strength higher than the structure in which the buried portion is provided by L-bending in the conventional fixed portion. it can. In addition, the inclined portion (buried portion) is formed by cutting and raising a part of the fixed portion, and the contact engaging portion is formed of resin flowing into the hole portion of the inclined portion cut and raised. Therefore, the thinness of the contact fixing portion is not impaired as in the conventional structure in which the embedded portion is provided by Z bending or L bending in the fixed portion. Further, the inclined portion is almost surrounded by the frame portion of the fixed portion except for the base end bent portion other than the distal end portion, and the distal end portion has an inclination angle with respect to the flow direction in the flow of the molten resin. Therefore, the inclined portion is not easily returned and deformed by the molding pressure at the time of insert molding. Even if the inclined portion is deformed, the inclined portion is cut and raised and a frame portion surrounding the hole portion is formed. Since it is cut and raised from the center of the fixed part, the length and width of the fixed part are not changed, and it is insulated like a conventional structure in which a buried part is provided by Z bending or L bending. There will be no defects. For this reason, it is not necessary to reduce the molding pressure at the time of insert molding, and it is easy to surely pour the molten resin into every corner in the mold, and it is difficult to cause molding defects. Therefore, productivity can be improved.

  According to a third aspect of the present invention, in the second aspect of the present invention, the contact engaging portion is surrounded by a plate surface on one side of the frame portion that is flush with one surface of the contact fixing portion. And the structure which forms the island-like surface located on the same surface as this board surface is added.

  With such an additional configuration, the contact engaging portion can be provided with the maximum strength by effectively utilizing the thickness of the portion to be fixed, so that the contact fixing strength can be effectively improved. Also, since the plate surface on one side of the fixed part is located on the same surface and exposed, the surface of the contact fixing part does not create unevenness that hooks it when connecting the connection object by cutting and raising the inclined part. Can be connected and disconnected smoothly.

The one-side inclined plate surface connected to the one-side plate surface of the fixed portion located in the contact fixing portion is substantially parallel to the one-side plate surface of the fixed portion positioned in the contact fixing portion on the distal end side. The structure which is bent like this is added.

  With such an additional configuration, even when the resin thickness of the contact fixing portion on the plate surface side on one side of the fixed portion is smaller than the thickness of the fixed portion, the contact fixing portion is located on the same surface as the one surface, Since a part of the plate surface on one side of the fixed portion exposed on one surface of the contact fixing portion can be positioned in the contact engaging portion by the inclined portion, the thickness of the contact fixing portion can be further reduced, and the inclined portion Since the contact engaging portion can be formed in the contact fixing portion by the resin flowing into the hole portion of the cut and raised trace, it is possible to improve the contact fixing strength fixed to the contact fixing portion further pursuing thinness.

  The invention according to claim 6 is the invention according to any one of claims 2 to 5, wherein the inclined portion is bent from the fixed portion along a width direction of the fixed portion. Is added.

  With such an additional configuration, even if the inclined portion does not move in the width direction of the fixed portion even if the inclined portion is deformed by the molding pressure at the time of insert molding, the inclined portion is not displaced in the width direction of the fixed portion. Reliable reliability can be ensured. Thereby, the contact fixing strength can be further improved.

  The invention according to claim 7 is the invention according to any one of claims 2 to 6, wherein the fixed portion includes a reinforcing portion that forms the inclined portion, the hole portion, and the frame portion. Each of the contact portions has a projecting portion projecting on both sides of the fixed portion, and is formed to be partially wide at the reinforcing portion, and the contact is different from the first contact in which the reinforcing portion is formed in the contact longitudinal direction. A configuration in which two types of second contacts are included and the first contacts and the second contacts are alternately arranged is added.

  With such an additional configuration, the reinforcing portions of each contact are arranged in a staggered manner, so that a larger inclined portion and contact engaging portion can be obtained without changing (increasing) the contact arrangement pitch. The contact fixing strength can be improved more effectively.

  With such an additional configuration, it is possible to reduce the thickness of the card connector by thinning the contact fixing portion of the body while increasing the fixing strength of the contact connected to the card.

  As described above, according to the present invention, in increasing the fixing strength of the contact (insert product), it is possible to prevent the contact fixing portion (molded product) from being damaged, and the contact is deformed by the molding pressure at the time of insert molding. It is difficult to cause insulation failure or the like even if it is deformed. It is easy to make the connector thinner.

The laterally long rectangular contact fixing portion 3f is provided.

  The plurality of contacts 4 that are insert products are formed by punching and bending a metal plate having a thickness (about 40 percent) thinner than the thickness of the contact fixing portion 3f, and each of them has electrical conductivity, and A fixed portion 4a that is fixed to the contact fixing portion 3f and extends in the card insertion / removal direction, that is, the front-rear direction, and a piece that is continuously and integrally extended in an upwardly inclined manner from the fixed portion 4a toward the rear side.

Established, Having a soldering portion 4f formed at the front end of the Ntakuto 4.

  Such a plurality of contacts 4 are arranged and fixed in such a manner that each fixed portion 4a is fixed to the contact fixing portion 3f at a constant pitch P in the left-right direction of the body 3 and with a predetermined interval therebetween. The bottom plate 3a of the body 3 is arrayed and fixed at a constant pitch P and with a predetermined interval therebetween.

  Each contact 4 extends in the front-rear direction of the body 3, and the plate surface on the upper side of the fixed portion 4a (left side in FIG. 4) is flush with the inner surface on the upper side (left side in FIG. 4) of the contact fixing portion 3f. Located, that is, the upper plate surface of the fixed portion 4a is exposed on the upper inner surface of the contact fixing portion 3f, and the lower plate surface (right side in FIG. 4) of the fixed portion 4a is in the contact fixing portion 3f. The fixed portion 4a is embedded and fixed in the contact fixing portion 3f by this thickness so that the spring portion 4b extends upward from the rear end face of the contact fixing portion 3f to the upper side of the hole 3d so as to be positioned at The contact portion 4c provided at the rear end portion of the contact 4 is cantilevered in the back of the card receiving space 1b so as to be elastically displaceable in the vertical direction, and the connecting portion 4d is cut out from the front end surface of the contact fixing portion 3f. Protruding into the back of the contact The soldering portion 4f at the front end of the lower end of the soldering portion 4f is disposed through the step portion 4e so that the lower plate surface is positioned on the same plane as the outer surface of the lower side of the contact fixing portion 3f (the right side in FIG. 4). It protrudes and supports at the back of the notch 3e.

  The card connector configured as described above is surface-mounted on a substrate (not shown) built in an electronic device such as a mobile phone, a digital camera, a portable audio, and a PDA, and each of the soldered portions 4f of the plurality of contacts 4 and the cover 2 The soldering part 2c for grounding formed by bending at the corner part (see FIG. 1) and the soldering part formed by bending the pair of spring contact pieces of the card detection switch are soldered to the corresponding land part of the board. Mechanically fixed and electrically connected. Then, as shown in FIG. 2, the contact portion 4c of the contact 4 is pressed from the lower side to the external connection terminal t of the card C which is inserted into the card receiving space 1b through the card receiving port 1a of the housing 1 and held in the mounting position. By making contact, power supply from the electronic device to the card C and transmission / reception of signals between the electronic device and the card C can be performed.

  The card connector is a connector suitable for reducing the overall thickness by reducing the thickness of the bottom plate 3a of the body 3, that is, the thickness of the contact fixing portion 3f. In the fixed portions 4a of the plurality of contacts 4 provided in the card connector, the upper plate surface is positioned on the same plane as the inner surface of the contact fixing portion 3f, and the lower plate surface is positioned in the contact fixing portion 3f. Thus, it is sufficient that the fixed portion 4a is embedded and fixed in the contact fixing portion 3f, and the resin fixing thickness of the contact fixing portion 3f is sufficient on one side of the fixed portion 4a, that is, both sides of the fixed portion 4a. Since the resin wall thickness of the contact fixing portion 3f is not required on the plate surface side, the card connector having a contact fixing structure that requires the resin wall thickness of the contact fixing portion 3f on the plate surface sides on both sides of the fixed portion 4a. In comparison, the thickness of the contact fixing portion 3f is small, and the whole is thin.

  Further, as shown in FIGS. 2, 3, 4A and 4B, the fixed portion 4a of each contact 4 has a hole 4g penetrating from the plate surface on one side to the plate surface on the opposite side. Have Thereby, the resin flows into the hole 4g of the fixed portion 4a during insert molding, and the contact area of the fixed portion 4g with the contact fixing portion 3f increases, so that the fixing strength of the contact 4 increases. In addition, since the increase in the contact area of the fixed portion 4a to the contact fixing portion 3f is a result of the resin flowing into the hole 4g of the fixed portion 4a at the time of insert molding, Unlike the structure in which the buried portion is provided by Z bending or L bending, the thinness of the contact fixing portion 3a is not impaired. In addition, since there is no embedded portion that may be deformed by the molding pressure during insert molding, the width and length of the fixed portion 4a are similar to the conventional structure in which the embedded portion is provided by Z bending or L bending. Is not changed (increased), and the contact timing difference between the contact portion 4c of the contact 4 and the external connection terminal t of the card C caused by the change in the length of the fixed portion 4a can be prevented. And the distance (insulation distance) between the fixed parts 4a can be kept at a set distance, and the width of the fixed part 4a increases and the distance between the fixed parts 4a decreases. It is possible to prevent insulation failure such as deterioration of insulation performance and short circuit caused by contact, and to secure necessary insulation. For this reason, it is not necessary to lower the molding pressure at the time of insert molding, and it is easy to surely pour the molten resin into every corner of the mold, so that molding defects are not easily caused and productivity can be improved.

  Further, the fixed portion 4a of each contact 4 has a claw that causes a part of the upper plate surface located on the same plane as the inner surface of the contact fixing portion 3f to protrude obliquely from the lower plate surface by cutting and raising. 4h, the hole portion 4g of the cut and raised trace of the inclined portion 4h, and a frame portion 4i surrounding the hole portion 4g, and the contact fixing portion 3f is a contact engagement that encloses the inclined portion 4h. Part 3g. Accordingly, a part of the upper plate surface of the fixed portion 4a that is located on the same surface as the inner surface of the contact fixing portion 3f and is exposed on the inner surface of the contact fixing portion 3f is formed by the inclined portion 4h. Therefore, it is equivalent to the conventional structure in which the buried portion is provided with Z-bending in the fixed portion, and the contact fixing strength is improved as compared with the conventional structure in which the buried portion is provided with L-bending in the fixed portion. be able to. When the card C is inserted into the card receiving space 1b through the card receiving port 1a of the housing 1, the spring part 4b when the contact part 4c of each contact 4 is pushed down with the bending of the spring part 4b on the lower surface of the card C. Can be received by the contact engaging portion 3g through the inclined portion 4h. In addition, the inclined portion (buried portion) 4h is formed by cutting and raising a part of the fixed portion 4a, and the contact engaging portion 3g is formed in the hole portion 4g of the cut and raised trace of the inclined portion 4h. Since it is made of resin that has flowed in, the thinness of the contact fixing portion 3f is not impaired as in the conventional structure in which the embedded portion is provided by Z bending or L bending in the fixed portion. Further, since the inclined portion 4h is almost surrounded by the frame portion 4i of the fixed portion 4a from the base end bent portion other than the distal end portion, the inclined portion 4h is returned and deformed by the molding pressure at the time of insert molding. Even if it is difficult to deform, the inclined portion 4h is cut and raised from the central portion in the width direction of the fixed portion 4a so as to form a hole portion 4g that is cut and raised and a frame portion 4i that surrounds the hole portion 4g. Therefore, the length and width of the fixed portion 4a are not changed, and the contact timing difference between the contact portion 4c of the contact 4 and the external connection terminal t of the card C caused by the change in the length of the fixed portion 4a is prevented. It is possible to obtain an appropriate contact timing, and it is possible to keep the interval (insulation distance) between the fixed parts 4a at a set distance, and the width of the fixed part 4a is increased to increase the fixed parts. Between 4a It is possible to prevent an insulation failure short circuit due to a decrease or a contact insulation performance caused by the smaller, it is possible to ensure the required insulation. Furthermore, the inclined portion 4h is not easily deformed by the molding pressure at the time of insert molding, and even if it is deformed, it does not cause problems such as a shift in contact timing or insulation failure, so it is necessary to lower the molding pressure at the time of insert molding. However, it is easy to surely pour the molten resin into every corner of the mold, and it is difficult to cause defective molding. For this reason, productivity can be improved.

  The contact engaging portion 3g of the contact fixing portion 3f is surrounded by the upper plate surface of the frame portion 4i located on the same plane as the inner surface of the contact fixing portion 3f, and is flush with the plate surface. An island-like surface 3h located at is formed. Thereby, since the maximum strength (thickness) can be given to the contact engaging portion 3g by effectively utilizing the thickness of the fixed portion 4a, it is possible to effectively improve the contact fixing strength. Further, since the upper plate surface of the fixed portion 4a is located on the same surface and exposed, the concave portion for hooking the card C at the time of insertion / extraction of the card C is not formed by the raised portion of the inclined portion 4h. The card C can be smoothly inserted and removed (connected / separated).

  Further, the inclined portion 4h of the fixed portion 4a is formed in a tapered shape. As a result, the contact 4 is less susceptible to the molding pressure during insert molding and is less likely to deform.

  Further, the inclined portion 4h of the fixed portion 4a has a corner dropping portion 4j in which a corner portion in the cut-and-raised direction on the tip side is dropped, and the lower side of the fixed portion 4a located in the contact fixing portion 3f. The lower inclined plate surface connected to the plate surface is bent so as to be substantially parallel to the lower plate surface of the fixed portion 4a located in the contact fixing portion 3f on the distal end side. Thus, even when the resin thickness of the contact fixing portion 3f on the lower plate surface side of the fixed portion 4a is smaller than the thickness of the fixed portion 4a, the contact fixing portion 3f is positioned on the same plane as the inner surface. Since a part of the upper plate surface of the fixed portion 4a exposed on the inner surface of the contact fixing portion 3f can be positioned in the contact engaging portion 3g by the inclined portion 4h, the thickness of the contact fixing portion 3f can be further increased. Since the contact engaging portion 3g can be formed in the contact fixing portion 3f with resin flowing into the hole 4g of the cut and raised trace of the inclined portion 4h, the contact fixing portion fixed to the contact fixing portion 3f further pursuing thinness can be formed. Strength can be improved.

  The inclined portion 4h of the fixed portion 4a is bent from the fixed portion 4h along the width direction of the fixed portion 4h. Thus, even if the inclined portion 4h is deformed by returning to the inclined portion 4h due to the molding pressure at the time of insert molding, the inclined portion 4h is not displaced in the width direction of the fixed portion 4a. Reliable reliability can be ensured. Thereby, the contact fixing strength can be further improved.

  Furthermore, the fixed portion 4a includes the protruding portions 4m and 4n that are formed on the opposite sides of the outer cover fixing portion, that is, the reinforcing portions 4k that form the inclined portion 4h, the hole 4g, and the frame portion 4i. The plurality of contacts 4 include two types of first and second contacts 4A and 2B, in which the positions where the reinforcing portions 4k are formed differ in the contact longitudinal direction. The first contacts 4A and the second contacts 4B are alternately arranged as shown in FIGS. As a result, the reinforcing portions 4k of the contacts 4 are arranged in a staggered manner, so that a larger inclined portion 4h and contact engaging portion 3g can be obtained without changing (increasing) the arrangement pitch of the plurality of contacts 4. Thus, the contact fixing strength can be improved more effectively.

  Further, the protruding portion of the reinforcing portion 4k of the first contact 4A facing in the longitudinal direction of the contact, that is, the front-rear direction, is set so that the angle of refraction of the crank-shaped gap formed between the fixed portions 4a of the contacts 4 is larger than a right angle. The front and rear side edges of the portions 4m and 4n and the front and rear side edges of the overhanging portions 4m and 4n in the reinforcing portion 4k of the second contact 4B are formed on inclined side edges having substantially the same inclination direction and angle. Thereby, since the fluidity | liquidity of the resin between the to-be-fixed parts 4a (narrow gap) of each contact 4 at the time of insert molding can be improved, it becomes difficult to cause a molding defect.
