Description of the Invention: [Technical Field] The present invention relates to a socket for plugging and unplugging a plurality of types of plug connectors having different numbers of contacts. [Prior Art] A conventional USB (Universal Serial Bus) connector disclosed in Japanese Laid-Open Patent Publication No. Hei No. Hei. No. Hei. No. Hei. No. 2002-75510 A connector or the like disclosed in the publication. The plug connector of the USB connector disclosed in Japanese Laid-Open Patent Publication No. Hei No. Hei. No. 1-40-271 has a plug body made of a synthetic resin which is formed into a flat rectangular parallelepiped shape, and a rectangular tube formed to cover the outer peripheral surface of the plug body. Metal plug housing. In the plug main body, a fitting recessed portion having a shape of a corner hole having a front opening is recessed, and a plurality of plug contacts (not shown) that are flexible are arranged in parallel in the fitting recess. ❹ On the other hand, as shown in Fig. 13, the socket connector 301 is provided with a socket body 330 made of synthetic resin, and the fitting projection 334 protrudes toward the front to fit the fitting of the plug connector. The recessed portion and the metal socket housing 340 cover the outer peripheral surface of the socket main body 330. A plurality of (five in the illustrated example) socket contacts 31 are provided side by side in the lateral direction (the bottom surface in FIG. 13) of the fitting projection 334 in a lateral direction, which is in contact with the plug of the plug connector. The parts are in contact with each other. However, if both of the plug housings are connected to the inside of the socket housing 340, the fitting projections 334 of the socket housing 340 are fitted into the fitting recesses of the 201029280 head connector, and as a result, The plug contact and the socket contact 310 are electrically connected in such a manner that they are in contact with each other in the up and down direction in FIG. Further, as in the above-described conventional example, when the number of contacts is specified by specifications or the like, if six or more contacts are required, for example, it is conceivable to arrange the first to the plurality of contacts from the sixth to the next. The space created by the manner in which the outer casing of the plug connector is enlarged in the longitudinal direction or the lateral direction. At this time, if the shape of the outer shape of the plug connector is matched, the number of contacts* of the socket housing toward the longitudinal direction is * according to the conventional number (for example, when the head connector is connected, the plug housing and the socket housing are A large gap is generated between the two. As a result, in order to connect the number of contacts thereof according to the specification, the socket housing of the socket connector is weakened to the plug housing of the plug connector, and when connected The invention is invented by the inventor, and the object of the invention is to provide a socket capable of connecting a plurality of types of plug connectors having different numbers of contacts, and the workability at the time of connection is not The present invention is a socket that is selectively connected to have different contacts to form a first plug and a second plug. The contact plug of the ! plug has only one set of first plug contacts, and the second plug The contact structure is provided with a set of additional plug contacts in addition to the set of first plug contacts. Further, the socket of the present invention is provided by an outer casing and an insulating base disposed in the outer casing. The outer casing is formed of a metal material and is composed of a pair of lower walls of the upper wall and a pair of side walls which are opposite to each other in the width direction. At the front end of the outer casing, a front opening is formed, which can be commonly received (received) Dimensions of the second plug and the second plug. The base is composed of the second carrier and the second carrier, and is equipped with a first socket that is electrically connected to the second plug contact. The second carrier is provided with a two-dimensionally arranged additional socket contact electrically connected to the additional plug contact. The first carrier is oriented from the second carrier toward the front along the longitudinal direction of the housing. The opening side extends and is placed close to the upper wall of the outer casing such that the first socket contact is located at a first height closer to the upper wall side than the lower wall, and the second height position is measured from the lowermost portion of the lower wall. The second carrier is placed behind the first carrier in the longitudinal direction of the outer casing, so that the additional socket contact is located rearward of the first socket contact, and the additional socket is provided. The arrangement of the contacts is located at the junction of the first socket Close to the second height of the lower wall, the second height is measured from the lowermost portion of the lower wall and is smaller than the second height. A portion of the lower wall is formed with a protrusion that faces the upper wall and protrudes from the remaining portion of the lower wall. A first height pitch is left between the G protrusion and the upper wall, and a second pitch is left between the lower wall and the upper wall other than the protrusion, and the first carrier and the first one are disposed in the first height interval. The socket contact 'arranges the second carrier and the additional socket contact in the second south span. By the present invention, when the first plug is connected, the protrusion maintains the connected first plug', thereby preventing the connection. The workability at the time of the first plug is lowered. In the socket of the present invention, it is preferable that the front end of the second carrier is formed to have a width larger than the width of the first carrier and abuts against the front end of the first plug. When the first plug is connected, the left and right full systems of the front end of the first plug 201029280 are in contact with each other, and the workability when the first plug is connected to the second plug is lowered. The front side of the carrier can improve the insertion force, and can further prevent the connection of the socket of the present invention. Preferably, the protrusion is formed at the center in the width direction of the lower wall, and the additional socket contact is divided into the first socket. 2 groups on both sides of the width direction of the point. Since the straw is made of 6 liters, the space inside the casing of the socket can be effectively utilized, so that the size can be reduced. It is preferable that the socket of the present month is opposed to the protrusion so that the first socket contact is disposed at the center in the width direction of the casing. According to the present invention, the contact pressure with respect to the first socket contact of the second plug contact of the second plug at the time of the first plug connection can be improved. In the socket of the present invention, it is preferable that the projections continuously extend from the front opening to the rear end of the second carrier. By the extension of the projection to the rear end of the second carrier, the contact pressure of the second plug contact of the second plug to the first socket contact can be further increased. ❹ In the socket of the present invention, it is preferred that the additional socket contacts are urged by the spring. Since the additional plug contact of the second plug is not required to be urged by the spring, it is possible to reduce the height of the socket. In the socket of the present invention, it is preferable that the additional socket contacts are formed by an anchor foot embedded in the groove formed in the second carrier and extending away from the anchor foot so as to be separated therefrom. a binding leg extending from a rear end of the anchoring foot to a rear end of the contact leg, and a terminal leg extending from the rear end of the anchoring foot and protruding on the base, the footing is coupled to impart a relative to the contact foot In the way that the anchor foot can be elastically deformed by the spring, the spring is forced to form and the 201029280 is formed. Thus, the additional socket contact can be easily formed. The first socket contacts of the present invention are preferably arranged in accordance with the specifications of the micro USB connector. With this arrangement, the first plug based on the specifications of the micro USB connector can prevent the workability at the time of connection from being lowered.

The first carrier 36 is formed so as to protrude forward from the upper portion of the front surface of the second carrier 34, and a plurality of (5) first socket contacts 10 are exposed on the bottom surface (see FIGS. 4 to 5). ). The first! The left and right widths and height dimensions of the carrier 36 are formed to be smaller than the left and right widths and height dimensions of the second carrier 34. The first socket contact 10 is formed by bending a strip-shaped metal plate into a hook shape, and has a main piece (not shown) inserted into the terminal carrier 32 and facing forward from the front end of the main piece The extended contact piece 12 and the terminal piece 14 extending rearward from the rear end of the main piece. Then, the contact pieces 12 of the first socket contact 1 are exposed at equal intervals in the left-right direction, and are exposed on the bottom surface of the first carrier 36 (see Figs. 4 to 5). The additional socket contact 20 shown in Fig. δ is formed by punching and bending. The additional socket contact 2 is formed by the anchor leg 22 embedded in the terminal groove 32 formed in the terminal carrier 32 of the base 3, extending along the anchor leg 22 so as to be separated therefrom. The contact leg 24 of 201029280, the engaging leg 26 extending from the rear end of the anchor leg 22 to the rear end of the contact leg 24, and the leg foot 28 extending from the rear end of the anchor leg 22 and projecting on the base '30 . The coupling leg 26 is formed in such a manner as to impart a spring for elastically deforming the contact leg 24 with respect to the anchor leg 22 so as to be freely deformable. By inserting the anchor leg 22 into the press-fitting groove 33 of the terminal carrier 32, and inserting the contact leg 24 into each of the holding grooves 35 as shown in Fig. 2, the additional socket contact 2 is added. The base portion 3 is attached to the bottom surface of the second reference carrier 34. Further, between the upper end of the contact leg 24 and the upper bottom surface of the holding groove 35, the contact leg 24 is flexed upward in the holding groove 35 due to the gap therebetween. The length of the base portion 3 of the socket 本 of the present embodiment is longer than the length of the base portion of the socket connector of the MicroUSB standard in the front-rear direction, and only the front-rear direction of the second carrier 34 that exposes the additional socket contact 20 is increased. The amount of length. According to the above configuration, the socket 1 of the present embodiment can overlap the mounting space of the additional socket contact 20 in the vertical direction and overlap the mounting space of the first socket contact 1〇. For example, in the terminal carrier 32, the anchoring foot 22 of the additional socket contact 2〇 and the rear end portion of the contact leg 24 can be attached by the mounting space of the main piece into which the i-th socket contact 10 is to be inserted. Therefore, in the socket 1' of the present embodiment, the amount of height of the base portion 30 due to the attachment of the additional socket contact 2' is minimized, so that the base portion 30 can be lowered. Seeking a socket! Low back. Further, when the maximum height of the base portion of the socket of the present invention is the reference, the maximum height increase of the base portion 30 of the socket 1 of the present embodiment is approximately only the fitting projection 238 of the second plug 200 (refer to the tenth aspect). Figure) The thickness of the figure. With the above configuration, the socket 1' of the present embodiment can reduce the mounting space of the additional socket contact 20 to the width of the base portion of the socket of the MicroUSB standard in the left-right direction. In other words, the socket 1 of the present embodiment does not have the additional socket contact 20, and the left-right width of the base portion 30 is larger than the width of the base portion of the micro USB-sized socket. Therefore, the base portion 30 can be downsized. Since the left-right width ‘ of the base 3〇 of the socket 1 of the present embodiment is equal to the left-right width of the base of the MicroUSB-sized socket, the size of the socket 1 can be reduced. The socket housing 40 is formed into a rectangular tube shape by a metal (for example, stainless steel) plate having corrosion resistance, and is composed of an upper wall 42, a lower wall 44, and a pair of side walls 46 which are opposite in the width direction. With a front opening 48. Further, the upper wall 42' is provided with an engaged portion (engaged hole) 4 3', and the engaging claws 162 and 262 are detachably engaged therein (see the fourth φ diagram). Then, the base portion 30 is inserted into the socket housing 1 through the rear opening of the socket housing 40, and the base portion 3 is fixed (stopped) on the socket housing 40 on the side of the terminal carrier 32. As shown in Fig. 2, the shape of the front opening 48 of the socket housing 40 is configured to collectively receive (receive) the first plug and the second plug 2''. In the present embodiment, the shape of the front opening 48 is similar to the cross-sectional shape of the front end of the second plug 200. As shown in the second and fourth figures, the lower wall 44 of the socket housing 4 has a central portion in the width direction, and covers the rear end 12 201029280 of the second carrier 34 from the front opening 48 (the front end of the terminal carrier 32). A projection 45 extending in the front-rear direction is formed so as to be curved toward the upper wall 42. Further, the height of the projection 45 substantially coincides with the thickness of the fitting projection 238 of the second plug 200 (see the j-th view). The distance between the top surface of the protrusion 45 and the upper wall 42 of the socket housing 40 in the vertical direction (the j-th height pitch H (J1) is the height dimension of the plug housing of the ith plug based on the MicroUSB standard. The maximum height of the plug 1 is substantially equal. Further, the distance between the lower wall 44 and the upper wall 42 other than the projection 45 of the socket housing 4 is the same as that of the second plug 2. The second plug 200 is formed such that the maximum height of the plug housing 240 (see Fig. 8) is substantially equal. That is, the maximum height of the socket housing 4 in the present embodiment is formed only by the socket of the MicroUSB standard. The maximum height is greater than the height of the projections 45. As shown in Fig. 1 to Fig. 4, in the state where the base portion 3 is inserted into the socket housing 40, the first pitch is HG1 $, and the first load is arranged. The cookware 36 and the first socket contact 1〇. At this time, the i-th socket contact is located at a certain height closer to the upper wall 42 than the lower wall 44 of the socket housing 4G (from the lower wall 44 of the socket housing 40 The lower i-th height η 〇 measured from the lower portion in a manner opposite to the protrusion 45 It is disposed at the center in the width direction of the socket housing 4. In addition, as shown in Fig. 2, the second carrier 34 and the additional socket contact 2 are disposed at the second height pitch HG2 $. At this time, the 帛 2 socket The contact 2 〇' is located near the lower wall 44 of the socket housing 40, which is smaller than the ith height H1 by 13 201029280 (the second height H2 measured from the lowermost portion of the lower wall 44 of the socket housing 40). Since the left and right widths of the base portion 30 are equal to the left and right widths of the base of the croUSB-type socket, the width dimension of the socket housing 40 in the present embodiment is also equal to the width dimension of the housing of the Micr〇USB-sized socket. Further, in the case of the socket housing 40 of the present embodiment, the amount of increase in size in the vertical direction and the front-rear direction is suppressed to a minimum when compared with the socket housing of the MicroUSB standard. Therefore, the socket® 1 can be miniaturized. In the socket of the embodiment, when the second plug is inserted and the second plug 200 is inserted, the inner side surface of the socket housing 40 and the outer surface of the plug housing are surely elastically contacted.

Terminal carrier 32 (see Figure 5). Further, as described above, the width dimension of the terminal carrier 232 of the second plug 2A is equal to the width dimension of the terminal carrier 132 of the second header. Therefore, the width dimension of the plug housing (10) of the second plug 200 is also formed. The width of the plug housing of the i-th plug, etc. ® In the present embodiment, only the second plug 2GG has a chasing plug contact 220 designed to be in a non-flexible configuration (a so-called tuning fork contact and an additional socket that is in elastic contact with the additional plug contact 22) The joints are exemplified by a flexible structure (so-called corrugated contact), but the structure of each contact is reversed. That is, the additional plug contacts (4) can be flexibly constructed and the additional socket contacts can be added. 20 is designed to be in a non-flexible configuration. When the first plug is connected to the socket housing 40 of the socket 1 of the present embodiment, the plug housing of the first plug is only accommodated in the protrusion of the housing 40 outside the socket 17 201029280 45 is a space above the base (the SU in the i-th figure. At this time, the first ^ insert head 34 is further front, and the lower end of the front end covers substantially the left and right and abuts the front of the insert: The outer (4) and the inner wall of the socket housing 4G are elastic, and the connection between the first plug and the socket i is made true: the first plug's contact is bent downward, and the first one is exposed on the ith carrier = the bottom surface. The socket contacts 1G are elastically contacted separately, so the two contacts Further, the contact is electrically connected. Further, the engagement between the engaging member (10) and the engaged portion 43 mechanically holds the combination of the first plug and the socket 1. The missing portion is provided at a protrusion 45 of 4° outside the seat. The cymbal is attached to the lower wall of the plug housing of the first plug, and the first plug is supported by the squirrel. Therefore, the contact pressure of the first plug contact of the third plug can be increased to make the connection i In the case where the second plug 200 is connected to the socket 1 of the present embodiment, the plug housing 24 of the second plug 200 is housed in the socket housing 40. The protrusion 45 is located below the space (S2 in the figure) in the rear of the second carrier 34 of the base (four). At this time, the lower end of the plug housing 240 of the (10) head 200 covers the entire left and right sides. It is connected to the front surface of the terminal carrier 32. Further, the first plug contact 210 of the second plug 2 is flexed downwardly and is exposed to the first socket contact 10 of the bottom surface of the carrier 36. Elastic contact, so that the second plug contact 21〇 and the first socket contact 1〇 are in contact with each other. Meanwhile, The pair of fitting projections 238 of the second plug 200 are housed in the space on both sides in the width direction of each of the projections 45 and lower than the bottom surface of the second carrier 34, and are exposed on the bottom surface of the second carrier 34. The contact pins 24 of the additional socket contacts 20 are bent upward, and are elastically contacted with the additional plug contacts 220 exposed on the top surface of the fitting projections (4), so that the plug contacts 22 and the additional sockets are added. The points 20 are in contact with each other, and the second plug 2 is supported by the lower wall 44 of the projection 45 so as to be connected to the lower portion of the plug housing 24 of the second plug 2''.插座The socket connector i of the implementation type, the number of the contact pieces and the shape of the outer casing (plug housing) (mainly the size) are different from the 2 types of plug connectors (the first! Both the plug and the second plug can be plugged and unplugged freely. Further, the socket connector of the present embodiment is provided in the socket housing 4 even when the ith plug which is smaller than the second plug 2G is connected. The protrusion 45, keep the number! Therefore, the plug housing of the plug does not deteriorate the workability when the first plug is connected. Moreover, the additional socket contact 2〇 which is in contact with the additional plug contact 220 of the second plug 200 is configured to be flexed upward, so that the additional plug contact 220 φ of the second plug 2〇〇 does not need to be deflected. freely. Therefore, since it is not necessary to additionally insert the space for the insertion of the (four) point 220 in the second plug, the size of the front end portion of the outer casing 240 of the second plug 200 can be relatively small in the vertical direction. As a result, the socket connector can be obtained. 1 low back. Further, in the present embodiment, the socket base portion 3 supports the additional socket connection that is in contact with the additional plug contact 22 of the second plug 200 at both sides of the projection 45 in the width direction of the socket housing 4A. Since the point is 20, the space inside the socket housing 4 can be effectively utilized for miniaturization. Further, the projections 45 are provided in the vertical direction of the outer casing 40, and are disposed at a position opposed to the first socket contact 10 which is in contact with the plug contact of the plug of the first illuminating contact, so that the second extension τ η can be improved. The contact pressure between the first plug contact and the first contact 110 is inserted. The sputum σ ^ is further advanced, and the projections 45 are continuously extended from the front opening 38 of the outer casing 40 to the rear end of the carrier 34, thereby improving the holding force of the first plug to the plug housing. The connector of the present invention is not limited to a connector based on a specific specification, and the connector is based on any specification (for example, a coffee specification or a 1394 specification). applicable.
