Description

  The present invention relates to a connector having a plurality of electrodes, and in particular, when a plug is pressed once, the connection between the plug and the jack is turned ON, and when pressed again, the connection is turned OFF, and this push-on- The present invention relates to a jack-type connector in a push-off type connector.

  Many AC-DC converters for converting a commercial AC power source into a DC power source are commercially available under the name of an AC adapter. This AC adapter rectifies input AC power and outputs DC power. The output DC power is supplied to a device (for example, a notebook computer or a mobile phone charger) that operates with DC power via a cable. A connector for connecting the cable and a DC power operating device (hereinafter simply referred to as “device”) is usually composed of a cable-side plug and a device-side jack. Thus, the plug and jack used for connecting the DC power source are referred to as a DC plug and a DC jack, respectively, and both are collectively referred to as a DC connector.

  To connect the DC plug at the end of the cable to a DC jack equipped on a device such as a laptop computer, push the DC plug into the DC jack. By this pushing operation, the negative electrode and the positive electrode of the DC plug come into contact with the negative electrode and the positive electrode of the DC jack, respectively, and the DC plug and the DC jack are electrically connected. The DC plug includes a rod-shaped tip electrode and an annular sleeve electrode coaxial with the tip electrode. As for the polarities of both electrodes, for example, the tip electrode is a positive electrode and the sleeve electrode is a negative electrode. The DC jack has an inner electrode that contacts the tip electrode of the DC plug and an outer electrode that contacts the sleeve electrode of the DC plug.

  8 and 9 are longitudinal sectional views conceptually showing the structure of a conventional DC connector. This DC connector includes a DC jack 100 and a DC plug 2. FIG. 8 shows a state before the DC jack 100 and the DC plug 2 are coupled, and FIG. 9 shows a state where the DC jack 100 and the DC plug 2 are coupled. The DC jack 100 includes an outer electrode 111 that is a − (minus) electrode, an inner electrode 112 that is a + (plus) electrode, a − electrode terminal 101, and a + electrode terminal 102. The outer electrode 111 and the inner electrode 112 are connected to the negative electrode terminal 101 and the positive electrode terminal 102, respectively. The outer electrode 111 and the inner electrode 112 are made of metal leaf springs such as phosphor bronze plated with gold. The DC plug 2 includes a sleeve electrode 21 that is a negative electrode and a tip electrode 22 that is a positive electrode.

  To connect the DC plug 2 and the DC jack 100 as shown in FIG. 9 when the DC jack 100 is fixed to the device, the DC plug 2 is pushed in the direction of arrow A in FIG. Pushing into the jack 100, the sleeve electrode 21 and the tip electrode 22 of the DC plug 2 are brought into contact with the outer electrode 111 and the inner electrode 112 of the DC jack 100, respectively. At this time (when in the connected state of FIG. 9), the outer electrode 111 (made of a leaf spring) of the DC jack 100 is in pressure contact with the sleeve electrode 21. The tip electrode 22 is inserted into the center space of the inner electrode 112 which is also made of a leaf spring and arranged in an annular shape, and the inner electrode 112 is in strong pressure contact with the tip electrode 22. As described above, in the conventional DC connector shown in FIGS. 8 and 9, the electrodes in the DC jack 100 and the DC plug 2 are strongly pressed against each other, so that the electrical connection on the surfaces of the electrodes in contact with each other is stabilized. Is planned.

JP 2001-357935 A

  When the DC jack 100 and the DC plug 2 are to be shifted from the connected state (FIG. 9) to the disconnected state (FIG. 8), the DC plug 2 is gripped with fingers and the direction opposite to the arrow A in FIG. Pull the DC plug 2 strongly to remove the DC plug 2 from the DC jack 100. Although the illustration of the right side (cable side) end of the DC plug 2 is omitted in FIG. 9, the right side (cable side) end of the DC plug 2 is actually about 1 cm outward from the right end of the DC jack 100. Since it protrudes, when the DC plug 2 is gripped with fingers, the protruding portion is gripped. In the operation of extracting the DC plug 2, since the electrodes of the jack DC jack 100 and the DC plug 2 are strongly pressed against each other, a considerably large force in the direction opposite to the arrow A in FIG. 8 is applied to the DC plug 2. There is a need. As described above, in the connected state of FIG. 9, the axial length of the DC plug 2 protruding rightward from the right end of the DC jack 100 is about 1 cm. When a force is applied to the DC plug 2 in the direction opposite to the arrow A, it is not easy to make the force large enough to extract the DC plug 2. Therefore, in the operation for removing the DC plug 2, not only the axial force of the DC plug 2 but also the force that tilts the axis of the DC plug 2 with respect to the axis of the DC jack 100 is applied to the DC plug 2, or the inclination It is apt to apply an excessive force to the DC jack 100 and the DC plug 2 by changing the direction of. As described above, when a force other than the axial direction, that is, a force having a component orthogonal to the axis, is applied to the DC plug 2, members of the DC jack 100 and the DC plug 2, such as the inner electrode 112, are broken or deformed. There are things to do. Further, the operation of pulling out the DC plug 2 from the DC jack 100 is a burdensome operation for the operator because a large force is required to grasp and pull the DC plug 2 with fingers.

  This facilitates the operation of pulling out a plug-type connector (hereinafter simply referred to as “plug” according to a common name) from a jack-type connector (hereinafter simply referred to as “jack”), and damages to the jack or plug during the extraction operation. In order to suppress this, for example, Japanese Patent Application Laid-Open No. 2001-357935 of “Patent Document 1” proposes a “connector fitting / detaching structure”. FIG. 1 of Patent Document 1 shows a male connector (4) having a guide groove (26) and a female connector (2) fitted to the male connector (4). The female connector (2) is provided with a driven pin (9). In order to fit the male connector (4) to the female connector (2) and to electrically connect the two connectors, the inlet of the guide groove (26) is aligned with the driven pin (9). (4) is advanced toward the female connector (2). The guide groove (26) is formed in a substantially heart shape. The guide groove (26) is provided with a lock portion (30 in FIG. 4) in the middle of the forward path and the backward path (end of the forward path). Insert the male connector (4) into the female connector (2) and slide the guide groove (26) and the driven pin (9) so that the male connector (4) faces the female connector (2). When pushed, the driven pin (9) is guided along the guide groove (26), and when the driven pin (9) reaches the lock portion, the male connector (4) is locked to the female connector (2) ( Fixed). When the male connector (4) is pushed toward the female connector (2) while in this locked state, the driven pin (9) is removed from the lock portion, and the male connector (4) is connected to the female connector ( 2) can be extracted. Such a fitting / removal structure between the male connector (4) and the female connector (2) is a push-push type connector structure, and the substantially heart-shaped guide groove (26) and the driven pin (9). It is comprised by the combination. The combination of the substantially heart-shaped guide groove (26) and the driven pin (9) used in this push-push type connector structure is a mechanism called a push-on / push-off type. FIGS. 4 to 6 show examples of a substantially heart-shaped guide groove.

  In the connector fitting / removal structure described in Patent Document 1 shown above, the male connector (4) and the female connector (2) are fitted and removed by the male connector (4). Simply push (push) towards the connector (2). However, in the structure of Patent Document 1 in which the connector can be engaged and disengaged only by this push, it is expected that a certain effect can be expected in the ease of operation and the suppression of connector damage during the operation of withdrawal (extraction). In order to enable the push-on / push-off operation, the male connector (4) is provided with a substantially heart-shaped guide groove (26), and the female connector (2) is provided with a driven pin (9). There is a need. Therefore, a special structure that enables push-on / push-off operation (also referred to as “alternate operation”) is required for both male and female connectors. Neither plugs nor jacks can be used.

  For example, when a jack for DC power input is provided on the notebook computer side and the cable end leading to the DC output of the AC adapter is used as a plug, the notebook computer manufacturer enables push-on / push-off operations. Even if a dedicated DC jack (jack-type connector) is mounted on a notebook computer, the DC plug (plug-type connector) provided at the end of the AC adapter DC output cable is a general-purpose product, and a commercially available AC adapter is used. It is desirable to be able to supply DC power.

  Therefore, the present invention provides a push-on / push-off type connector and a jack that facilitate the operation of removing the plug from the jack, suppress damage to the jack and plug during the removal operation, and enable the use of a general-purpose plug. Objective.

  Preferred embodiments of a push-on / push-off connector according to the present invention will be described below with reference to the accompanying drawings.

(Features of the present invention)
Prior to the description of the embodiments of the present invention, an outline of the features of the present invention will be described first. In the push-on / push-off type connector according to the present invention, the jack has a push-on / push-off mechanism, and the plug is held in the jack by first pushing the plug into the jack, that is, the first push of the plug. By pushing the plug for the second time in the hold state where the plug is held by the jack, the hold state is released and the plug is pushed out from the jack. The direction in which the plug is pushed out from the jack is opposite to the direction in which the plug is pushed. By adopting this push-on / push-off type connector according to the present invention, it is not necessary to forcefully pull the plug out of the jack by hand to release the hold state, so the jack or plug may be damaged during the hold release operation. Can be greatly reduced. This push-on / push-off mechanism only needs to be provided in the jack, and the jack having the push-on / push-off mechanism can be combined with a general-purpose plug. Therefore, the push-on / push-off type connector according to the present invention facilitates the operation of removing the plug from the jack, can suppress damage to the jack and the plug during the extraction operation, and enables the use of a general-purpose plug. It is.

  More specifically, the jack in the push-on / push-off type connector according to the present invention is such that when the floating base supported by a spring urging in the direction of pulling out the plug is pushed by the first push of the plug, The heart-shaped rotating cam mechanism provided on the housing or the floating base locks the floating base, and the first and second electrodes of the plug are sandwiched and held by the first and second leaf spring electrodes of the jack. This leads to a hold state in which the jack holds the plug. When the second push is applied to the plug in this hold state, the lock by the heart-shaped rotating cam mechanism is released, the floating base is pushed out in the opposite direction to the push by the spring, and the hold state is released. . That is, when the plug is pushed once in the axial direction, the plug and the jack are held, and when the plug is pushed once again in the axial direction, the hold state is released and the plug can be pulled out from the jack.

  Hereinafter, the push-on / push-off type connector of the present invention will be described in detail. Since the jack of the present invention is a jack constituting the push-on / push-off type connector, the jack is also described in the description of the push-on / push-off type connector.

(Detailed description of the embodiment with reference to the drawings)
Next, the present invention will be described more specifically with reference to the drawings. FIG. 1 is a longitudinal sectional view conceptually showing a push-on / push-off type connector comprising a DC jack and a DC plug according to an embodiment of the present invention. The push-on / push-off type connector of this embodiment is a DC jack 1 and a DC plug 2. The DC jack 1 and the DC plug 2 have a cylindrical casing, and the inner diameter of the cylindrical casing of the DC jack 1 is slightly larger than the outer diameter of the cylindrical casing of the DC plug 2. As shown in FIG. 1, the DC plug 2 is inserted into the DC jack 1 with its axes aligned. When the DC plug 2 is further pushed into the back side of the DC jack 1, both electrodes are in contact with each other, and both are held in a state where the electrodes are in contact. When the DC plug 2 is coupled to the DC jack 1, the DC jack 1 and the DC plug 2 are thus maintained in a state where the electrodes are in contact with each other and are in contact with each other, that is, in a holding state. It has become.

  The DC jack 1 includes a spring (compression coil spring) 9, a heart-shaped rotating cam 10, an outer electrode (−pole) 11 made of a leaf spring, an inner electrode (+ pole) 12 made of a leaf spring, a floating base 13, a rod 14, a housing. It has a minus (−) electrode terminal 101 and a plus (+) electrode terminal 102 which are fixed electrodes fixed to the body. The outer electrode (-pole) 11 made of a leaf spring and the inner electrode (+ pole) 12 made of a leaf spring are made of metal having elasticity. The heart-shaped rotating cam 10 is fixed to the casing of the DC jack 1. The DC plug 2 includes a sleeve electrode 21 and a tip electrode 22. The sleeve electrode 21 has a cylindrical shape, and the tip electrode 22 has a thin cylindrical rod-like body. The cylindrical sleeve electrode 21 and the columnar tip electrode 22 are coaxial.

  The floating base 13 has a cylindrical side wall, and a disk-shaped plate (a member with hatching in the drawing. The front plate is hereinafter referred to as a front plate) having circular openings 13a and 13b on the surface side (right side in the drawing). It is a can-shaped hollow body covered with a disk-shaped bottom plate 13e on the bottom side (left side in the figure). On the cylindrical side wall of the floating base 13, slits extending in the axial direction are opened on the upper side and the lower side in the figure. However, the upper and lower slits are omitted in the figure.

  The outer electrode 11 made of a leaf spring has one end fixed to the negative electrode terminal 101, extends from the negative electrode terminal 101 in a direction perpendicular to the axis of the cylindrical housing of the DC jack 1, and passes through the upper slit of the floating base 13. While slightly drawing a curve, it extends downward to the bent portion 11a, reverses at the bent portion 11a, bends at the bent portion 11b, extends in the axial direction of the casing of the DC jack 1 and the floating base 13, and opens the circular opening 13a. I'm going through. The other end of the outer electrode 11 ending through the circular opening 13a is formed into a waveform as shown in the figure.

  The inner electrode 12 made of a leaf spring has one end fixed to the + electrode terminal 102, extends from the + electrode terminal 102 in a direction perpendicular to the axis of the cylindrical housing of the DC jack 1, and forms a slit on the lower side of the floating base 13. While passing through a slight curve, it extends upward to the bent portion 12a, reverses at the bent portion 12a, bends at the bent portion 12b, extends in the axial direction of the casing of the DC jack 1 and the floating base 13, and has a circular opening 13b. Through. The other end portion of the inner electrode 12 that terminates through the circular opening 13b is bent and formed outward by about 45 degrees as shown.

  Next, the operation when the DC plug 2 is coupled to the DC jack 1 will be described in detail. The inner wall surface of the DC jack 1 and the outer wall surface of the DC plug 2 are molded so that the inner wall of the DC jack 1 and the outer wall of the DC plug 2 are in contact with each other and can be slid to be inserted and removed. First, as shown in FIG. 1, when the DC plug 2 is inserted into the DC jack 1 and the DC plug 2 is pushed (pushed) in the direction of the arrow A in the figure, as shown in FIG. Comes into contact with the floating base 13. In the state of FIG. 2, the front plate of the floating base 13 is separated from the bent portion 11 a of the outer electrode 11 and the bent portion 12 a of the inner electrode 12.

  When the DC plug 2 is further pushed (pushed) from the state of FIG. 2 in the direction of arrow A in the figure, the front plate of the floating base 13 is pushed to the tip of the DC plug 2 as shown in FIG. The front plate of the base 13 is in contact with the bent portion 11 a of the outer electrode 11 and the bent portion 12 a of the inner electrode 12. In the process in which the floating base 13 is pushed from the state of FIG. 2 to the state of FIG. 3, the spring 9 is compressed between the bottom surface of the DC jack 1 and the bottom plate 13 e of the floating base 13. A force to push back in the direction opposite to A is continuously applied to the floating base 13. When the plug 2 is pushed from the state of FIG. 2 to the state of FIG. 3, a force against the reaction force of the spring 9 is applied to the plug 2.

  In the process in which the floating base 13 is pushed from the state of FIG. 2 to the state of FIG. 3, the guide pin 14 b fitted in the guide groove 10 a of the heart-shaped rotating cam 10 is a rod corresponding to the amount of movement of the floating base 13. 14 and is moved in the direction of arrow C. The fixed block 13f fixed to the bottom plate 13e of the floating base 13 is provided with a bearing 13g. One end of the rod 14 is axially coupled to the bearing 13g and can freely rotate. The guide pin 14b is provided at the other end of the rod 14, is fitted into the guide groove 10a of the heart-shaped rotating cam 10, and one end of the rod 14 (the portion axially coupled to the bearing 13g) is connected to the DC jack 1. As it moves back and forth in the axial direction, it is guided in the guide groove 10a and moves clockwise. A portion drawn by a thick line in the guide groove 10a of the heart-shaped rotating cam 10 indicates a height difference (step) in the guide groove 10a. These height differences are provided in order to define that the guide pin 14b can move in the guide groove 10a only in one direction. In the present embodiment, the guide pin 14b is provided with a height difference so that the guide pin 14b can move only in the clockwise direction in the guide groove 10a. The heart-shaped rotating cam 10 is a cam known as a cam having an alternate operation mechanism. The alternate operation mechanism is used for an operating mechanism of a push-on / push-off type push button switch. As an alternate operation mechanism, a heart-shaped cam system, a rotating cam system, a ratchet cam system, and the like are known. As for the alternate operation mechanism, “Small Button Switch”, “Basic Knowledge of Control Equipment Selection / How to Use Switch / Indicator” (August 2001), Japan Electric Control Equipment Manufacturers Association, page 51, FIG. 8 Described in the heart cam method.

  FIG. 4 shows a state where the DC plug 2 is further pushed (pushed) in the direction of arrow A in the figure from the state of FIG. When the floating base 13 is pushed further from the state of FIG. 3 toward the back side of the DC jack 1 by being pushed by the DC plug 2, the rod 14 is also pushed in that direction, and the guide pin 14b is moved in the direction of arrow D in FIG. Proceeding and once reaching the farthest side, it becomes a dead end, and the pushing of the DC plug 2 stops there. The operator who has pushed the DC plug 2 toward the back of the DC jack 1 feels that the DC plug 2 has been pushed to the limit that can be pushed into the DC jack 1 by stopping the pushing of the DC plug 2. Stop pushing the DC plug 2 and release your finger from the DC plug 2. Then, once it is guided to the inner end of the guide groove 10a and becomes a dead end, and the force pushing the DC plug 2 is removed, the floating base 13 is pushed back in the direction of arrow B in FIG. In response to this pushing back, the guide pin 14b advances in the direction of arrow E in FIG. 4 and stops at the position shown in FIG. 4 (the center position on the back side of the guide groove 10a). This state is a state where the heart-shaped rotating cam 10 is locked.

  The fixing pins 13 c and 13 d are fixed to the casing of the DC jack 1. In order to allow the floating base 13 to move in the axial direction of the DC jack 1 without being blocked by the fixing pins 13c and 13d, a slit slightly wider than the thickness of the fixing pins 13c and 13d is opened on the side wall of the floating base 13. It is. However, illustration of these slits is omitted.

  As shown in FIGS. 3 and 4, in the process of shifting from the state of FIG. 3 to the state of FIG. 4, the front plate of the floating base 13 is pushed by the tip of the DC plug 2, and the front plate of the floating base 13 is the outer electrode. 11 bent portions 11 a and the bent portion 12 a of the inner electrode 12 are pushed toward the back of the DC jack 1. At this time, the outer electrode 11 is bent in the direction of arrow J between the fixed pin 13c and the bent portion 11a, and the inner electrode 12 is bent in the direction of arrow K between the fixed pin 13d and the bent portion 12a.

  As shown in FIG. 4, when the heart-shaped rotating cam 10 is locked, the outer electrode 11 is bent in the direction of the arrow J between the fixed pin 13c and the bent portion 11a, so that the outer side beyond the bent portion 11b. The electrode 11 is bent in the axial direction of the casing of the DC jack 1 and in the direction of arrow L in FIG. 4, and the tip (the other end of the outer electrode 11 described above) is pressed against the sleeve electrode 21 of the DC plug 2.

  At this time, the inner electrode 12 is bent in the direction of the arrow K between the fixed pin 13d and the bent portion 12a in the same manner as the outer electrode 11, so that the inner electrode 12 ahead of the bent portion 12b is the housing of the DC jack 1. It is bent in the axial direction of the body, in the direction of arrow M in FIG. 4, and the tip (the other end of the inner electrode 12 described above) is pressed against the tip electrode 22 of the DC plug 2.

  Since the arrows L and M in FIG. 4 are directions facing each other, the DC plug 2 is sandwiched between the distal end portion of the outer electrode 11 and the distal end portion of the inner electrode 12 and is held by the DC jack 1. This state is a state in which the DC plug 2 is held by the DC jack 1. FIG. 4 shows that the DC plug 2 is held by the DC jack 1 when the heart-shaped rotating cam 10 is locked.

  Next, an operation for extracting the DC jack 1 held by the DC plug 2 from the DC plug 2 will be described. The operation of pulling out the DC jack 1 held by the DC plug 2 from the DC plug 2 is in the state shown in FIG. 4, that is, pushing the DC plug 2 in the holding state in the direction of arrow A in FIG. It is. The heart-shaped rotating cam 10 is unlocked by the second pushing of the DC plug 2 and the guide pin 14b advances in the direction of arrow F as shown in FIG. When the guide pin 14b reaches the innermost side of the guide groove 10a of the rotary cam 10 and the guide pin 14b reaches a dead end point (the innermost point) and stops, the pushing of the DC plug 2 stops. The operator who is pushing the DC plug 2 feels that the pushing of the DC plug 2 has reached the limit. When the finger is released from the DC plug 2, the floating base 13 is pushed back by the elasticity of the spring 9. Accordingly, the guide pin 14b advances in the direction G in FIG. 5, reaches the state shown in FIG. 6, that is, the point shown in FIG. 1 (the point at which the floating base 13 is pushed most shallowly in the DC jack 1), and the guide pin 14b stops. .

  As the guide pin 14b is advanced in the direction of arrow G in FIG. 5, the floating base 13 and the DC plug 2 are pushed out in the direction of arrow B in FIG. In this process, since the floating base 13 is pushed out in the right direction in the figure, the bending of the outer electrode 11 between the fixing pin 13c and the bent portion 11a (FIG. 4) returns to the direction indicated by the arrow P in FIG. Similarly, the bending (FIG. 4) of the inner electrode 12 between the fixing pin 13d and the bent portion 12a returns to the direction indicated by the arrow Q in FIG.

  When the bending of the outer electrode 11 returns in this way, the tip of the outer electrode 11 that is inclined toward the axis of the DC jack 1 and pressed against the sleeve electrode 21 moves in the direction indicated by the arrow R in FIG. The contact with the sleeve electrode 21 is released. Similarly, when the bending of the inner electrode 12 returns, the tip of the inner electrode 12 which is inclined to approach the axis of the DC jack 1 and is pressed against the tip electrode 22 moves in the direction indicated by the arrow S in FIG. The contact with the tip electrode 22 is released.

  As described above, the locked state of the heart-shaped rotating cam 10 is released, and the elastic force of the spring 9 causes the guide pin 14b to advance in the guide groove 10a in the direction of arrow G (FIG. 5), so that the floating base 13 and the DC plug 2 are In the process of being pushed out and proceeding in the direction of arrow B in FIG. 5, the DC plug 2 sandwiched between the distal end portion of the outer electrode 11 and the distal end portion of the inner electrode 12 is When the guide pin 14b reaches the right end of the guide groove 10a (FIG. 6), the pushing of the floating base 13 stops, but the DC plug 2 is pushed out in the direction of arrow B in FIG.
