Description

  The present invention relates to a receptacle connector that is mounted on an electronic device such as a personal computer, a mobile phone, or a smartphone and that is connected to a plug connector provided in another device.

  Electronic devices such as personal computers, mobile phones, and smartphones are provided with receptacle connectors for connecting to plug connectors provided in other devices. One example is a micro-USB standard-compliant interface connector. Such a receptacle connector is deformed by repeatedly inserting and removing the plug connector. An invention for preventing such deformation of the receptacle connector is disclosed (for example, Patent Document 1).

JP 2004-087462 A

  The USB connector 10 with a lock mechanism described in Patent Document 1 is formed by a receptacle-side shell 13 enclosing a resin portion 15. Here, there is a concern about high cost because a mold is used to form the resin portion 15. In addition, there is a fact that instead of the resin portion 15, a material that uses a cylindrical shield formed by pressing a thin metal plate is widely used. Therefore, the inventor has considered a technique for preventing the deformation of the receptacle connector made using such a shield as in the first virtual example and the second virtual example shown below.

  FIG. 6 is a perspective view of the receptacle connector 801 in the first virtual example as seen from the front side. FIG. 7 is a perspective view of the receptacle connector 801 in the first virtual example viewed from the back side. A receptacle connector 801 shown as a first hypothetical example includes a cylindrical shield 803 that forms a flat first opening 802 and a housing 805 that fits into a second opening 804 of the shield 803 opposite to the first opening 802. And having. A plug connector (not shown) is attached to the first opening 802, and a contact (not shown) provided in the plug connector contacts a terminal 806 provided in the housing 805 and positioned in the shield 803. A leg portion 807 protruding downward from the shield 803 is formed by bending a portion protruding from the second opening 804 side of the shield 803 or cutting and raising the lower surface of the shield 803. The shield 803 is fixed to the substrate 808 by soldering the lower surface of the shield 803 to the upper surface of the substrate 808 in a state where the leg portion 807 is inserted into the insertion hole 809 formed in the substrate 808.

  The receptacle connector 801 of the first virtual example is covered with the reinforcing metal fitting 810 after being fixed to the substrate 808. The reinforcing metal fitting 810 has a U-shape that opens downward when viewed from the first opening 802 side. A leg portion 811 extending in a direction away from the shield 803 is provided below the reinforcing metal fitting 810. The reinforcing metal fitting 810 is attached to the shield 803 from above, and the leg portion 811 is soldered to the upper surface of the substrate 808. Accordingly, the reinforcing metal fitting 810 reinforces the shield 803 by being in contact with the upper surface of the shield 803 and sandwiching both side surfaces of the shield 803.

  Here, the receptacle connector 801 shown in the first hypothetical example is fixed to the substrate 808 by covering the shield 803 after the shield 803 is fixed to the substrate 808. For this reason, it is necessary to perform soldering in a narrow gap between the side surface of the shield 803 and the upper surface of the substrate 808, and it is difficult to align the reinforcing metal fitting 810 with respect to the shield 803. Further, the shield 803 and the reinforcing metal fitting 810 are not fixed to each other, and the shield 803 may be displaced with respect to the reinforcing metal fitting 810 when the plug connector is inserted. Further, there is no contact between the reinforcing bracket 810 and the housing 805, and the reinforcing bracket 810 does not contribute to fixing the housing 805.

  FIG. 8 is a perspective view of the receptacle connector 901 in the second hypothetical example. The receptacle connector 901 shown as the second virtual example is one in which the shield 902 and the reinforcing metal fitting 903 are integrally formed by folding back a part of the metal plate for forming the shield 803 of the second virtual example. . In this receptacle connector 901, problems relating to alignment and misalignment between the shield 803 and the reinforcing metal fitting 810 in the second hypothetical example are solved. However, the reinforcing metal fitting 903 does not contribute to fixing the housing (not shown). Furthermore, when the metal plate is folded back, a gap 904 is generated between the upper surface of the shield 902 and the lower surface of the reinforcing metal fitting 903, and another problem that the shield 902 and the reinforcing metal fitting 903 are not firmly fixed is caused.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a receptacle connector having a double shell structure that can be easily fixed to a substrate and is strong.

  The receptacle connector of the present invention has (α) a cylindrical shape extending in the Y direction, having a pair of first side portions parallel to the XY plane and a pair of second side portions parallel to the XZ plane as seen in the XYZ coordinate system. None, a shield through which the plug connector is inserted from the first end, and (β) is attached from the second end of the shield, and is prevented from coming off to the first end by the end face of the second end. A housing having a fitting tube portion positioned outside the shield and extending in the Y direction; (γ) a terminal extending from the housing and positioned in the shield and contacting a contact provided in the plug connector; and (δ) A base that is in contact with the outer surface of one of the first side portions, a clamping portion that extends from the base and sandwiches the second side portion from the outside, and a fitting portion that extends from the base and fits into the fitting tube portion. , Move in the Z direction And a reinforcing bracket for fixing the said housing in a state of being mounted and Rudo to the shield.

  According to the present invention, the shield, the housing, and the reinforcing metal member are held together, so that the receptacle connector having the double shell structure is strong. Further, the receptacle connector can be handled in a state in which the shield, the housing, and the reinforcing metal fitting are assembled, and the receptacle connector can be easily fixed to the substrate.

  One embodiment will be described with reference to FIGS. 1 to 4. For convenience of explanation, this embodiment is referred to as a first embodiment. In the present embodiment, the XY direction indicated in the claims is shown in the horizontal direction and the Z direction is shown in the vertical direction, but this is for explanation, and the XYZ direction is It is not limited to examples.

  FIG. 1 is a perspective view of the receptacle connector 101 as viewed from the upper front side. FIG. 2 is a perspective view of the receptacle connector 101 as viewed from the upper back side. FIG. 3 is a perspective view of the receptacle connector 101 as viewed from the lower back side. In FIG. 2, the outer shape of the reinforcing metal fitting 104 is shown by a frame for explanation. Also, the plug connector 201 is shown only in FIG. The receptacle connector 101 includes a shield 102, a housing 103, a terminal 103a, and a reinforcing metal fitting 104.

  The shield 102 is formed into a cylindrical shape having a substantially rectangular cross section by pressing a conductive thin plate such as copper, a copper alloy, an aluminum alloy, or stainless steel. As a result, the shield 102 has a pair of first side portions 102 a arranged vertically and parallel to each other, and a pair of second side portions 102 b arranged in the width direction B of the receptacle connector 101 and parallel to each other. A plug mounting hole 102d through which the plug connector 201 is inserted is opened at one end (first end 102c) of the shield 102.

  The housing 103 is formed by resin molding and mounted in a housing mounting hole 102f (see FIG. 4) formed in the other end (second end 102e) of the shield 102. The housing 103 has a fitting cylinder portion 103b extending in the vertical direction. The details of the shape of the housing 103 will be described later with reference to FIG. 4, and an outline will be described here.

  The terminal 103a is formed integrally with the housing 103 in a state where a plurality of contact members are arranged in the width direction B, and is extended in a cantilever state. A portion of the terminal 103 a is positioned in the shield 102 when the housing 103 is attached to the shield 102. The terminal 103a comes into contact with a contact 202 provided on the plug connector 201 attached to the shield 102, and becomes a part of an electric signal transmission path.

  The fitting cylinder portion 103b forms a part of the housing 103, extends in the vertical direction, and has a cylindrical shape with a long and narrow cross section. When the housing 103 is attached to the shield 102, the fitting cylinder portion 103b is positioned at a location that contacts the second end 102e outside the shield 102. At this time, the end surface of the second end portion 102e is caught by the outer peripheral surface of the fitting tube portion 103b, thereby preventing the housing 103 from being detached from the first end portion 102c.

  The reinforcing metal fitting 104 is attached to the shield 102 by moving downward from above the shield 102 and fixes both the shield 102 and the housing 103 attached to the shield 102. The details of the shape of the reinforcing metal fitting 104 will be described later with reference to FIG.

  The reinforcing metal fitting 104 is formed by pressing a conductive thin plate made of copper, copper alloy, aluminum alloy, stainless steel or the like. The reinforcing metal fitting 104 has a base portion 104 a that is in contact with the outer surface of the first side portion 102 a above the shield 102. From both sides of the base portion 104a in the width direction B, the sandwiching portion 104b extends downward. The sandwiching portion 104b sandwiches the second side portion 102b of the shield 102 from the outside and prevents the shield 102 from moving in the width direction B. In addition, a fitting portion 104c extends from an edge portion of the base portion 104a close to the second end portion 102e side of the shield 102. The fitting portion 104 c is fitted into the fitting cylinder portion 103 b when the reinforcing metal fitting 104 is attached to the housing 103. The tip of the fitting portion 104c is a leg portion 104d. The leg 104d is inserted into an insertion hole 302 formed in the substrate 301 when the receptacle connector 101 is soldered to the substrate 301 (shown only in FIG. 1). Such a leg portion 104 d also protrudes from the lower end of the sandwiching portion 104 b of the reinforcing metal fitting 104.

  FIG. 4 is an exploded perspective view of the receptacle connector 101. Based on FIG. 4, details of the structure of the shield 102, the housing 103, and the reinforcing metal fitting 104, and a method for assembling the receptacle connector 101 will be described.

  First, the shield 102 will be described. A snap claw 111 is provided on each of the pair of second side portions 102 b of the shield 102. The snap claw 111 is formed by cutting and raising a conductive thin plate constituting the shield 102 in the outer direction of the shield 102.

  A caulking portion 112 extends from the first side portion 102 a above the shield 102. When the conductive thin plate constituting the shield 102 is pressed, the caulking portion 112 extends in the extending direction of the first side portion 102a as shown by a one-dot chain line in FIG. A hole 112 a is formed in the caulking portion 112.

  A plug engagement claw 113 is provided on the first side portion 102 a above the shield 102. The plug engaging claw 113 is formed by cutting and raising a conductive thin plate constituting the shield 102 downward. The plug engaging claw 113 has an engaging groove 203 (see FIG. 2) formed in the plug connector 201 when the plug connector 201 (see FIG. 2) is inserted through the plug mounting hole 102d (see FIG. 1). The plug connector 201 is difficult to be removed from the receptacle connector 101. Here, the base 104 a of the reinforcing metal fitting 104 is provided with a relief hole 121 at a location corresponding to the plug engagement claw 113. A plug engagement claw 113 that is spring-backed when the plug connector 201 is inserted and removed enters the escape hole 121.

  The first side portion 102a below the shield 102 and the end portion on the second end portion 102e side are spaced apart at the central portion in the width direction B, and the pair of inner end portions 102g sandwiching the separated portions are located upward. It is bent. Thereby, the end surface on the second end portion 102e side of the shield 102 has a spiral shape that is wound inside.

  First fitting holes 114 are provided at two locations symmetrical in the width direction B in the region near the second end portion 102 e on the first side portion 102 a above the shield 102. The first fitting hole 114 opens in a rectangular shape that is long in the insertion direction A of the plug connector 201 (see FIG. 2).

  The shield 102 is provided with a second fitting hole 115. The second fitting hole 115 is aligned with the first fitting hole 114 in the width direction B and is symmetric in the width direction B, and is a boundary between the second side portion 102b and the upper first side portion 102a. It is provided at the place that covers the part. The first fitting hole 114 opens in a short rectangular shape in the insertion direction A of the plug connector 201 (see FIG. 2).

  Next, the housing 103 will be described. The housing 103 has a symmetrical shape in the width direction B, and tapers from the fitting tube portion 103b toward the mounting portion 132 and the terminal holding portion 131.

  The housing 103 has a terminal holding part 131. The terminal holding portion 131 is positioned in the shield 102 when the housing 103 is attached to the shield 102 and is closest to the first end portion 102c. From the terminal holding part 131, one end part of the terminal 103a contacting the contact 202 (see FIG. 2) of the plug connector 201 is exposed.

  The housing 103 has a mounting part 132 between the terminal holding part 131 and the fitting cylinder part 103b. When the housing 103 is mounted on the shield 102, the mounting portion 132 is fitted into the second end portion 102e side of the shield 102 in a slightly press-fitted state, and contacts the inner wall surface of the second end portion 102e.

  The above-described fitting cylinder portion 103b is located on the opposite side of the housing 103 from the terminal holding portion 131 and is provided at two positions symmetrical in the width direction B. The fitting cylinder portion 103b is formed so as to protrude outward from the mounting portion 132 when viewed from the first end portion 102c side. For this reason, almost all of the end surface on the second end portion 102e side of the shield 102 having a spiral shape comes into contact.

  From the region between the two fitting cylinder portions 103b in the housing 103, the terminal 103a described above is bent in a direction away from the mounting portion 132 after extending downward. This end (the other end of the terminal 103a) is connected to a land pattern (not shown) provided on the upper surface of the plug connector 201.

  In the housing 103, a prismatic protrusion 133 protrudes from the upper surface of the mounting portion 132. The protrusion 133 is provided close to the fitting tube portion 103b at the center in the width direction B of the mounting portion 132. The protrusion 133 enters the hole 112 a when the housing 103 is attached to the shield 102. In this state, the crimping portion 112 is bent as shown by a one-dot chain line in FIG. 4, so that the housing 103 is crimped and fixed to the shield 102.

  Next, the reinforcing metal fitting 104 will be described. The sandwiching portion 104b of the reinforcing metal fitting 104 is formed at substantially the same height as the second side portion 102b. For this reason, the leg portion 104 d protruding from the lower end of the clamping portion 104 b protrudes below the shield 102 when the reinforcing metal fitting 104 is attached to the housing 103.

  A snap engagement hole 122 is opened at a position corresponding to the snap claw 111 of the shield 102 in the sandwiching portion 104 b of the reinforcing metal fitting 104. The snap engagement hole 122 engages with the snap claw 111 and is fixed by a snap lock when the reinforcing metal fitting 104 is attached to the housing 103.

  The fitting portion 104c described above is shaped to be fitted to the fitting cylinder portion 103b, and corresponds to each of the two fitting cylinder portions 103b of the housing 103 in the width direction B of the base portion 104a of the reinforcing metal fitting 104. It extends from both ends. Such a fitting part 104c is longer than the length of the fitting cylinder part 103b. A press-fitting protrusion 104e protrudes from the side surface of the fitting portion 104c facing in the width direction B. The fitting portion 104 c is press-fitted into the fitting cylinder portion 103 b when the reinforcing metal fitting 104 is attached to the housing 103. When press-fitted, the press-fitting protrusion 104e is caught on the inner wall surface of the fitting cylinder portion 103b, and the reinforcing metal fitting 104 is prevented from coming out of the housing 103 upward. Further, the leg 104d provided at the tip of the fitting portion 104c is provided at the same height as the leg 104d protruding from the lower end of the holding portion 104b, and this fitting is performed when the fitting tube portion 103b is inserted. It protrudes downward from the tube portion 103b.

  A first fitting protrusion 123 is provided on the base 104 a of the reinforcing metal fitting 104. The first fitting protrusion 123 is provided at a location corresponding to the first fitting hole 114 of the shield 102. The first fitting protrusion 123 is formed by inserting two cut lines in the insertion direction A and pushing downward between the cut lines. When the reinforcing metal fitting 104 is attached to the housing 103, the first fitting protrusion 123 is fitted into the first fitting hole 114. Here, even if the reinforcing metal fitting 104 tries to move in the width direction B with respect to the shield 102, the end surface of the first fitting protrusion 123 facing the width direction B contacts the inner wall surface of the first fitting hole 114 to reinforce. The movement of the metal fitting 104 in the width direction B is prevented.

  The reinforcing fitting 104 is provided with a second fitting protrusion 124 over the boundary portion between the base portion 104a and the sandwiching portion 104b. The second fitting protrusion 124 is provided at a location corresponding to the second fitting hole 115 of the shield 102. The second fitting protrusion 124 is formed by inserting two cut lines in the width direction B and pressing between the cut lines to compress in the thickness direction. When the reinforcing metal fitting 104 is attached to the housing 103, the second fitting protrusion 124 is fitted into the second fitting hole 115. Here, even if the reinforcing metal fitting 104 tries to move in the width direction B with respect to the shield 102, the end surface of the second fitting protrusion 124 facing the insertion direction A comes into contact with the inner wall surface of the second fitting hole 115 to reinforce. The movement of the metal fitting 104 in the insertion direction A is prevented.

  As described above, the first fitting hole 114, the first fitting protrusion 123 fitted into the first fitting hole 114, and the second fitting hole 115 and the second fitting protrusion 124 fitted into the second fitting hole 115 are formed as described above. The reinforcing metal fitting 104 is prevented from moving in the plane direction. Here, the concave-convex fitting portion 126 is configured.

  Here, both the first fitting protrusion 123 and the second fitting protrusion 124 are connected to the reinforcing metal fitting 104 while being supported at both ends. For this reason, even if the shield 102 moves in the plane direction with respect to the reinforcing metal fitting 104, the first fitting protrusion 123 and the second fitting protrusion 124 are unlikely to be detached from the reinforcing metal fitting 104. Further, since the second fitting protrusion 124 is formed by compressing the boundary portion between the base portion 104a and the sandwiching portion 104b, the thickness increases, the strength increases, and it becomes more difficult to come off.

  Receptacle connector 101 is manufactured by the following procedure. First, the housing 103 enters the housing mounting hole 102f from the terminal holding part 131 and is inserted into the housing mounting hole 102f on the second end 102e side of the shield 102. At this time, the mounting portion 132 is fitted into the second end portion 102 e of the shield 102. In addition, the fitting cylinder portion 103 b hits the end surface of the second end portion 102 e of the shield 102. Further, the protrusion 133 enters the hole 112 a of the crimping portion 112.

  Subsequently, the caulking portion 112 of the shield 102 is bent, and the housing 103 is caulked and fixed to the shield 102.

  Subsequently, the reinforcing metal fitting 104 is fitted from above the shield 102. At this time, the snap engagement hole 122 and the snap claw 111 are snap-locked. The fitting portion 104c is press-fitted and fixed to the fitting cylinder portion 103b. The first fitting protrusion 123 is fitted into the first fitting hole 114. Further, the second fitting protrusion 124 is fitted into the second fitting hole 115.

  As described above, the receptacle connector 101 of the present embodiment is configured by assembling the shield 102, the housing 103, and the reinforcing metal fitting 104, and these three members are held together. Therefore, the receptacle connector 101 has a double shell structure and is strong.

  Thus, the receptacle connector 101 of the present embodiment can be handled in a state where the shield, the housing, and the reinforcing metal fitting are assembled. That is, when the receptacle connector 101 is fixed to the substrate 301 (see FIG. 2), the leg 104d is inserted into the insertion hole 302 (see FIG. 2) of the substrate 301 without separately soldering the shield 102 and the reinforcing metal fitting 104. The receptacle connector 101 can be fixed to the substrate 301 at a time by inserting and soldering the lower surface of the first side portion 102 a below the shield 102 to the upper surface of the substrate 301. That is, the receptacle connector 101 can be easily fixed to the substrate 301.

  Further, the receptacle connector 101 according to the present embodiment is shielded by caulking the housing with a shield, press-fitting the fitting portion 104c into the fitting cylinder portion 103b, and snap locking between the snap claw 111 and the snap engagement hole 122. The reinforcing metal fitting 104 cannot be removed from the 102 or the housing 103.

  As another embodiment (second embodiment) according to the first embodiment, the first fitting protrusion 123 and the second fitting protrusion 124 provided on the reinforcing metal fitting 104 are extruded. Instead of forming, a U-shaped cut line may be inserted into the reinforcing metal fitting 104 to cut it up and formed in a cantilever state.

  As still another embodiment (third embodiment) according to the first embodiment, a protrusion is welded and fixed to the lower surface of the base portion 104a of the reinforcing metal fitting 104 to be provided in the reinforcing metal fitting 104. The fitting protrusion 123 and the second fitting protrusion 124 may be formed.

  Next, still another embodiment will be described with reference to FIG. For convenience of explanation, this embodiment will be referred to as a fourth embodiment. This embodiment conforms to the first embodiment, and the same reference numerals are used for the same parts as those in the first embodiment, and description thereof is omitted.

  FIG. 5 is a perspective view of the receptacle connector 101 as viewed from the lower front side. In the present embodiment, leg portions 104f are formed by being cut and raised on the first side portion 102a below the shield 102 at approximately two positions in the width direction B at the approximate center in the insertion direction A. The leg portion 104f is inserted into the insertion hole 302 (see FIG. 2) of the substrate 301 in the same manner as the leg portion 104d provided in the sandwiching portion 104b and the fitting portion 104c of the reinforcing metal fitting 104.

  Also in the receptacle connector 101 of the present embodiment, the shield 102, the housing 103, and the reinforcing metal fitting 104 are assembled to each other, and these three members are held together so that the receptacle connector 101 has a double shell structure. It will be solid. Further, the receptacle connector 101 can be fixed to the substrate 301 at a time. Further, in the receptacle connector 101 of the present embodiment, since the shield 102 and the housing 103 both have leg portions 104d and 104f and are inserted into the substrate 301, the fixing of the receptacle connector 101 to the substrate 301 is further strengthened.

  Needless to say, the portions specifically described in each embodiment can be combined with other embodiments as appropriate.
