[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector with a switching function for electrically connecting a header and a socket and having a power switch part which is opened and closed in accordance with the attachment and detachment of the header and the socket. Is.

[0002]

2. Description of the Related Art In recent years, portable telephones have become widespread, and when this type of portable telephone is used in an automobile, an external device mounted on the vehicle is installed to prevent consumption of a battery built in the telephone. It is desirable to supply power from a power source. In order to achieve this purpose, conventionally, a telephone is provided with a switch or a relay for power supply switching, and when an external power supply is connected, the connection of the external power supply is mechanically or electrically detected to detect the internal and external power supplies. It was switching. However, in this conventional example, since a switch and a relay are separately required, there is a problem that the number of parts is increased and the cost is increased. In addition, since it is necessary to provide a space for arranging switches and relays inside the telephone, there is a problem that it becomes a factor that hinders downsizing of the telephone.

Therefore, recently, a connector with a switching function as shown in FIG. 1 has been proposed. Such a connector with a switching function is used, for example, for switching between an internal power supply and an external power supply of a mobile phone, and has a header housing 31 having an opening on one side, and a header contact of a conductor is made in the opening of the header housing 31. A header 30 in which a child 32 is arranged with one end facing the opening;
A socket housing 41 is detachably coupled to the header housing 31 such that one surface is open and the header contact 32 is inserted into the opening.
In the opening, a socket contact 42 made of a conductor is provided with a socket 40 arranged so that one end of the socket contact 42 can contact the header contact 32. The socket housing 41 is provided with a contact pressing portion 3 which is inserted into the opening of the header housing 31 when it is coupled to the header housing 31, and the contact pressing portion 3 is formed with an inclined surface 48 '.
A fixed contact 33 and a switching contact 35, which are arranged to face each other, are provided in the opening of the header housing 31.
Of the header contact 32 is provided separately from the header contact 32. The movable contact 34 is urged to come into contact with the fixed contact 33 so that the header housing 31 and the socket housing 41 are connected to each other. The movable contact 34 is separated from the fixed contact 33 by being pressed by the contact pressing portion 3 at the time of coupling.

Here, the power switch portion for opening and closing an internal power supply circuit (not shown) is turned on and off by contact and separation of the movable contact 34 and the fixed contact 33 in the header housing 31, and the socket housing. When the 41 and the header housing 31 are not fitted to each other, the power switch section is turned on so that power is supplied from the internal power source.
On the other hand, the socket housing 41 and the header housing 31
When mated with socket contact 42 and header contact 32
Power is supplied from an external power source via and. As a result, there is an advantage that it is not necessary to separately provide a switch or a relay for switching the power supply accompanying the connection of the external power supply, and the detection of attachment / detachment can be realized with a small number of parts and space saving.

[0005]

However, the on / off timing of the switching of the power supply switch portion in the conventional connector with a switching function is determined by the timing of attachment / detachment of the socket housing and the header housing. Therefore, in the prior art, the switching function compatible with MBB is available. It was necessary to separately prepare a connector with a switching function and a connector with a switching function capable of supporting the BBM. Moreover, conventionally, as shown in FIGS. 33 to 35, the angle α of the inclined surface 48 ′ of the socket housing for separating the movable contact 34 and the fixed contact 33 from each other is set to the tip 34 a of the movable contact 34. Since it is set to about 35 °, which is the same as the inclination angle α ₁ , the wiping effect of the contact portion between the movable contact 34 and the fixed contact 33 at the time of opening / closing the power switch is small, and therefore the cleaning effect of the contact portion is obtained. However, there was a problem that troubles such as poor contact occurred. 33 to 35, 1'is a connector with a switching function, 2'is a plug, and 4'is a receptacle.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a time difference function to the switching means by arbitrarily changing the timing of the power switch section by changing the shape of the socket housing. Another object of the present invention is to provide a connector with a switching function that can be held, and further, wiping is generated when the contact portion of the power switch portion is opened and closed to enhance the cleaning effect and maintain stable contact.

[0007]

In order to solve the above-mentioned problems, the present invention has a header housing 31 having an opening on one side, and a header contactor 32 made of a conductor has one end opened in the opening of the header housing 31. And a socket housing 41 that is detachably coupled to the header housing 31 in such a manner that one surface is open and the header contactor 32 is inserted into the opening. A socket contact 42 made of a conductive material is provided in an opening of the housing 41 with a socket 40 arranged so that one end of the socket contact 42 can contact the header contact 32, and the socket housing 41 is coupled to the header housing 31. A contact pressing portion 3 which is sometimes inserted into the opening of the header housing 31 is provided, and an inclined surface 48 is formed in the contact pressing portion 3 so that the contact pressing portion 3 is inserted into the opening of the header 30. Is provided separately from the header contactor 32, and includes a fixed contactor 33 and a movable contactor 34 arranged opposite to each other. The movable contactor 34 is urged to contact the fixed contactor 33. When the header housing 31 and the socket housing 41 are joined together, they are arranged so as to be separated from the fixed contact 33 by being pressed by the inclined surface 48 of the contact pressing portion 3 and the position of the inclined surface 48 of the contact pressing portion 3. Is changed to change the timing of contact between the socket contact 42 and the header contact 32.

The inclined surface 4 of the contact pressing portion 3
8 is the first position P _{1 at} which the movable contact 34 is pressed by the inclined surface 48 before the contact between the socket contact 42 and the header contact 32, and the movable contact 34 by the inclined surface 48. The second position P after the pressing operation of P is performed after the contact between the socket contact 42 and the header contact 32.
_It is preferable that it can be changed to any of the _two .

Also, the inclined surface 4 of the contact pressing portion 3
It is preferable that the angle 8 is about 45 ° or more with respect to the insertion direction A of the socket housing 41.

[0010]

According to the above construction, by changing the position of the inclined surface 48 provided on the contact pressing portion 3 so as to face the movable contact 34, the socket contact 42 and the header contact 3 are formed.
Since the timing of contact with 2 can be freely changed, that is, the timing of the power switch unit 22 can be changed only by changing the shape of the socket housing 41,
The timing of the power switch unit 22 is set to the socket contact 42.
It can be arbitrarily shifted before or after the time point at which the header contactor 32 and the header contactor 32 are in contact with each other (at the time point when the power supply from the external power source is started), so that the switching means has the time difference function.

Further, when the angle of the inclined surface 48 is about 45 ° or more with respect to the insertion direction A of the socket housing 41, when the angle is 45 °, the pressing force of the movable contact 34 by the inclined surface 48 is increased. The upper component force and the horizontal component force are approximately half, but at a larger angle, the horizontal component force exceeds the upper component force, and the movable contact 34 is horizontally moved by the inclined surface 48 when the socket is fitted. It is disengaged from the fixed contact 33 while being strongly pressed. Therefore, wiping occurs at the time of opening and closing the contact portion of the power switch unit 22, the cleaning effect becomes large, and trouble such as contact failure can be prevented.

EXAMPLE 1 Example 1 of the present invention is shown in FIGS.
It shows in FIG. The connector with a switching function used in this embodiment is used for switching between an internal power supply and an external power supply of a portable telephone, and includes a receptacle 4 having a header 30 and a plug 2 having a socket 40. Composed. In FIG. 1, a header 30 is provided with a rectangular parallelepiped synthetic resin header housing 31 having an opening on the front surface, and a header contactor 32 made of a leaf spring of a conductor is exposed in the opening at one end thereof. Arranged in a shape. In addition, a fixed contact 33 is inserted from the rear surface into the header housing 31, and a switching contact (power supply terminal) made of a conductive plate spring integrally provided with a movable contact 34 facing the fixed contact 33. 35 is arranged with the movable contact 34 inserted in the header housing 31. As shown in FIGS. 7 to 11, the switching contact 35 is integrally provided with a contact piece 35 a that is inserted into a holding groove 37 provided on the upper surface of the header housing 31. A pair of the holding grooves 37 is provided, and the other holding groove 37 is provided.
A contact piece 36a of another switching contact (power supply terminal) 36 having no movable contactor is inserted in this. The fixed contact 33 and the switching contact 36 are provided with terminal pieces 33a and 36b, respectively.

The movable contactor 34 has a spring force so as to come into contact with the fixed contactor 33, and has a header housing 31.
The projecting dimension inward is such that the movable contact 3 is larger than the fixed contact 33.
4 is set larger. Header housing 3
1 has a pair of fixing protrusions 38 formed in a substantially L shape on its rear surface.
When mounting on the printed circuit board 21, the header housing 31 can be positioned with respect to the printed circuit board 21 by inserting the tip end of the fixing protrusion 38 into the through hole formed in the printed circuit board 21. It has become.
Further, when the header housing 31 is positioned on the printed circuit board 21, the terminal piece 32a (FIG. 1) of the header contactor 32 protruding from the rear surface of the header housing 31,
The fixed contact 33 and the terminal pieces 33a and 36b of the switching contact 36 are adapted to abut on the surface of the printed board 21, respectively. Therefore, the terminal piece 32
By soldering a, 33a, and 36b to the printed board 21, the printed board 21 and the header 30 can be easily electrically connected. The contact pieces 35a, 36a of the switching contacts 35, 36 are connected to the internal power supply of the telephone. That is, the contact with the internal power source is made by elastically contacting the contact pieces 35a, 36a with a switching contact such as a battery pack having a built-in secondary battery.

By the way, as shown in FIG. 1, an insertion cylinder portion 43 provided in a housing 41 constituting the socket 40 is detachably inserted into the opening of the header housing 31. A front surface of the insertion tube portion 43 is opened, and a socket contact 42 made of a pin-shaped conductor is arranged in the opening so as to correspond to the movable contact 34 of the header 30. Further, on the upper surface of the insertion tube portion 43, as shown in FIG.
A pair of guide ribs 44 are provided in a protruding manner, and the guide ribs 44 are formed in the guide groove 39 provided at the opening peripheral edge of the header housing 31.
(FIG. 9). Therefore, the socket 30
When 0 is connected, the guide rib 44 and the guide groove 39 are engaged with each other to position them, and the movable contact 34
Touches the corresponding socket contact 42. A lock spring 46 having a hook 45 at the tip is provided on both side surfaces of the socket housing 41, and the lock spring 46 is inserted into the opening of the header housing 31 at the time of coupling with the header housing 31.
By engaging the hook 45 with the lock hole 31a (FIG. 7) provided in the header 30, the header 30 and the socket 40 are prevented from coming off. When the socket 40 is separated from the header 30 in the retaining state, the operating portion 47 that abuts on the lock spring 46 is pushed to push the hook 45.
And the lock hole 31a are disengaged from each other, and the socket 40
Should be pulled out from the header 30. In addition, in FIG.
Reference numerals 1 and 82 are receptacle cases, 83 is a coaxial connector assembly block, and 84 is a signal contact, which are housed in the casing 4a.

In the socket housing 41, an inclined surface 48 as an operating element is formed on the outer surface (contact pressing portion 3) on one side of the opening peripheral edge. This inclined surface 4
As shown in FIG. 4, 8 is a movable contactor 3 on the header 30 side.
4 is inclined at an angle of about 45 ° or more with respect to the insertion direction of the socket housing 41.
Here, the socket housing 41 and the header housing 3
The movable contact 34 and the fixed contact 33 are short-circuited at the contact portion 35a inside the header housing 31 when the socket housing 41 and the header housing 31 are not fitted. Inclined surface 48 of pressing portion 3
Is inserted and presses the movable contact 34,
Rides on the inclined surface 48 and opens. At this time the inclined surface 4
When the inclination angle of 8 is 45 °, the pressing force applied to the movable contactor 34 is half and half of the upper component force and the horizontal component force. Will exceed. That is, if the inclination angle α (FIG. 33) as in the conventional case is about 35 °, the upper component force exceeds the horizontal component force, and the fixed contact is quickly lifted from the fixed contact and the horizontal pushing force is increased. Although no pressure can be obtained, in contrast to this, by setting the inclination angle θ to be 45 ° or more as in the present invention, the movable contact 34 is strongly pressed in the horizontal direction while being in contact with the fixed contact 33 in the initial state. While being separated, the movable contact 34 is separated from the fixed contact 33.
The wiping mechanism can be provided in the contact portion 35a between the fixed contactor 34 and the fixed contactor 34, and thus the cleaning effect of the contact portion 35a becomes large, and stable contact can be maintained for a long period of time as compared with the prior art, and contact failure, etc. There is an advantage that the occurrence of trouble can be prevented. Further, by making the angle θ of the inclined surface 48 larger than 45 °, the lifting operation of the fixed contact 34 is performed more quickly after wiping, the on / off switching speed of the switch is accelerated, and the arc generation during energization switching is generated. There is also an advantage that The inclination angle θ ₁ of the tip of the movable contact 34 may be 45 ° or less.

The position of the inclined surface 48 in the socket housing 41 can be changed as shown in FIGS. 3 (a) and 3 (b). That is, when the inclined surface 48 is formed at the position shown in FIG.
The pressing operation of the movable contactor 34 by the inclined surface 48 is performed before the contact between the socket contactor 42 and the header contactor 32. Therefore, as shown in FIG. Before the (fixed contact 33 and movable contact 34) are switched from on to off, the external power supply circuit (socket contact 42 and header contact 32) is switched from off to on, so-called MBB operation is performed. . On the other hand, the inclined surface 48 is provided on the contact pressing portion 3
When the movable contact 34 is formed at the position shown in FIG. 3 (b) away from the tip of the socket, the pressing operation of the movable contact 34 by the inclined surface 48 is performed at the timing after the contact between the socket contact 42 and the header contact 32. Therefore, FIG. 2 (b)
As shown in FIG. 5, after the internal power supply circuit is switched from ON to OFF, the external power supply circuit is switched from OFF to ON, so-called BBM operation is performed.

In the above construction, when the header 30 and the socket 40 shown in FIG.
4 is in contact with the fixed contact 33, as shown in FIG.
When the header 30 and the socket 40 shown in (c) are fitted together, the movable contactor 34 rides on the inclined surface 48, and the movable contactor 34 separates from the fixed contactor 33. Therefore, the power switch unit 22 that is opened and closed by the inclined surface 48 that is the operator can be configured by the fixed contact 33 and the movable contact 34 provided in the header housing 31.

The power switch unit 22 is portable.
8 is used when switching the power supply of the telephone 23 of FIG.
The internal power supply E to the telephone circuit 24₁Power supply from
Insert the power switch section 22 into the path and

Becomes the internal power supply E₁Powers the telephone circuit 42 from
It In addition, the external power source E₂Power switch part
22 is turned off and the external power supply E₂From the telephone circuit 4
It will be charged.

Moreover, by changing the shape of the socket housing 41 and changing the position of the inclined surface 48, the switching timing of the power switch section 22 can be adjusted as shown in FIG.
Since it can be changed as in (a) and (b), there is an advantage that the switching means can be provided with a time difference function, and the existing connector with a switching function can be applied to both MBB and BBM.

Further, since the inclined surface 48 of the socket housing 41 is inclined at an angle of about 45 ° or more,
Contact portion 35a between the movable contact 34 and the fixed contact 33
Wiping occurs and the cleaning effect becomes large,
Stable contact can be maintained for a long time, troubles such as poor contact can be prevented, and the moving contact 34 is lifted more quickly after wiping, which speeds up the on / off switching of the switch. ,
There is also an advantage that the arc generation at the time of energization switching is reduced. (Embodiment 2) A second embodiment of the present invention is shown in FIGS. In this embodiment, the lock hand pusher 10 is integrated with the socket housing 11 in the connector with switching function to reduce the number of parts. Generally, FIG.
As shown in Fig. 1, the lock hand pusher 10 'and the metal lock piece 1
Although 2'is formed as a separate part or is formed by simultaneous molding, in this case, a die for the lock pushing portion is required. Therefore, as an improvement thereof, as shown in FIG. 14, a lock hand pushing portion 10 made of an integrally molded product joined to a socket housing 11 by a hinge is provided to make the lock hand pushing portion 10 rotatable, and the metal lock piece 12 is attached to the socket housing 11. Lock hand push part 1 at the same time when press-fitting into
The metal lock piece 12 can be inserted and fixed in the groove of 0. This eliminates the need for a die for the lock pushing portion, thus reducing the number of parts. Moreover, in this embodiment, it is only necessary to bend the lock pushing portion 10 by 90 ° and insert the metal lock piece 12 into the socket housing 11.
Since the metal lock piece 12 can be press-fitted into the lock hand pushing part 10 at the same time, there is an advantage that the number of assembling steps can be reduced. (Embodiment 3) A third embodiment of the present invention is shown in FIGS. In this embodiment, a certain lock strength can be maintained when the connector with switching function is fitted. Conventionally, when forcibly pulling out the lock breaking strength between connectors, the lock portion is broken and the pulling-out lock strength after the second time is lowered. On the other hand, in this embodiment, as shown in FIG. 25, the lock fitting 13 on the receptacle 4 side is press-fitted into the body and fixed to the inner wall. Further, as shown in FIG. 27, the lock arm claw portion 14 provided on the lock fitting 16 on the plug 2 side is horizontally 90 °.
Although it is bent, the lock arm pawl portion 14 of 90 ° may be crushed if the pulling out is performed in this case as well. Therefore, in order to allow the lock fitting 13 to swing from the inner wall, the tip of the hooking portion of the lock arm claw portion 14 is rounded, so that when the lock arm claw portion 14 is forcibly removed, the lock arm claw portion is rounded. The lock fitting 13 comes out along the portion 14, and the lock fitting 13 swings from the inner wall, so that the lock arm claw portion 14
There is an advantage that the force applied to the armature is reduced and it is difficult to deform. (Embodiment 4) A fourth embodiment of the present invention is shown in FIGS. Conventionally, as shown in FIGS. 36 and 37, when the socket is fitted, the common terminal 50 ′ is the NO terminal 51 ′ of the plug 2.
Is connected to an external high frequency signal by short-circuiting to the NC terminal 52 '.
Is separated from the common terminal 50 'and floats from the shield terminal, so that the high frequency characteristics (especially isolation) in the high frequency band tend to be inferior. 36 in FIG.
0 and 91 are insulators. Similarly, in FIG. 38, in the case where the socket is fitted, an N-shaped insulator is coated on one surface between the contact portions of the common terminal 50 ″ and the NC terminal 52 ″.
The O terminal 51 ″ is inserted to short-circuit the common terminal 50 ″ with the NO terminal 51 ″, and the NC terminal 52 ″ is brought into contact with the insulator, but this case also has a similar tendency.

On the other hand, in this embodiment, FIGS.
As shown in FIG. 2, the socket contact provided on the socket housing on the plug 2 side is
As shown in FIG. 30, the header contact formed by the terminal 51, the insulator 58a, and the shield portion 54a and provided in the header housing on the receptacle 4 side is formed by the common terminal 50 and the NC terminal 52. Therefore, the NC terminal 52 and the common terminal 50 (high-frequency signal section) are short-circuited in the socket not fitted state, and the common terminal 50 is short-circuited to the NO terminal 51 in the socket fitted state as shown in FIG. 32. Connected to an external signal, and the NC terminal 52 is connected to the common terminal 5
It is separated from 0, short-circuited with the shield part 54a, and grounded to the ground. As a result, the high frequency characteristics (especially isolation) in the high frequency band are excellent. In FIG. 30, 54 is a shield terminal, 58 is an insulator, 55 is a coaxial cable in FIG. 31, 56 is a coaxial shield part joined to the shield part 54a by soldering, and 57 is a coaxial line center conductor. .
