BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device (hereinafter referred to as a receiver) exemplified by a receiver (speaker), a microphone, and a vibrator, which has terminals on the back surface, electrically and mechanically on a printed wiring board. To a connector for electrically connecting.

[0002]

2. Description of the Related Art Generally, as a method for mounting an electronic component on a printed wiring board, for example, flux and solder are placed at the connection between the two, and the solder is melted by heating the flux and solder in a reflow furnace to print the electronic component. A mounting method by so-called reflow soldering, which is to bond to a board, is widely adopted. However, when a receiver or the like is mounted on a printed wiring board by reflow soldering, the cone is affected by being exposed to high temperature, the characteristics of sound quality are changed, and desired product quality cannot be obtained.

Therefore, conventionally, for example, as shown in FIG. 8 (a), a harness (b) connected to a terminal of a receiver or the like (a) is connected via a pair of plug connector (c) and receptacle connector (d). A so-called lead wire type connection structure, which is to connect to a printed wiring board, has been adopted. According to this connection structure, for example, the receptacle connector (d) is mounted on the printed wiring board at the stage of reflow soldering, and the receiver (a) is temporarily fixed to the printed wiring board or the like in the next step, and the harness ( By connecting the plug connector (c) attached to the end of (b) to the receptacle connector (d) on the printed wiring board, the receiver and the like (a) can be electrically and mechanically connected to the printed wiring board without exposing to high temperature. can do.

Further, as shown in FIG. 8B, a so-called spring type connection structure is known. This is done by putting a conductive plate-like piece on the terminal on the back of the receiver etc.
One end of the spring member (e) formed by bending it into a letter shape is fixed, and this receiver or the like (a) is temporarily fixed to the product casing on the front side, and then the printed wiring board is attached to the casing. The receiver and the like (a) and the spring member (e) are sandwiched between the casing and the printed wiring board while the (e) is compressed. By doing so, the clamping force is increased by the restoring force of the compressed spring member (e), and the other end of the spring member (e) is pressed against the conductor of the printed wiring board, etc. It will be possible to electrically and mechanically connect to the printed wiring board without exposing it to high temperatures.

[0005]

However, the lead wire type connection structure requires a harness (b), a plug connector (c) and a receptacle connector (d) in addition to the receiver and the like (a). Moreover, in the process of assembling the receiver or the like (a), the harness (b) is attached to the receiver or the like (a).
Are attached, these are attached to a printed wiring board or the like, and the plug connector (c) is connected to the receptacle connector (d), which requires a series of operations, but these operations are only manual operations, and automation is difficult. Therefore, the cost is high and mass production is difficult.

Further, in the spring type connection structure, since the thin spring member (e) is fixed to the terminal of the receiver or the like (a) in a cantilevered state, when the receiver or the like (a) is temporarily fixed to the casing. If another member hits the spring member (e) when attaching the printed wiring board to the casing or casing, the spring member (e) is easily deformed by the external force, and if this happens, the connection between the receiver etc. (a) and the printed wiring board will be poor. And so on. In addition, unless the accuracy of the mounting position of the spring member (e) on the receiver etc. (a) and the dimensional accuracy of the casing and the printed wiring board are kept high, the relative position of each member will shift and the receiver and the like (a) will be printed. There is a high possibility of causing a poor connection with the wiring board. For this reason, it is difficult to secure the connection performance of the receiver or the like (a) with the printed wiring board.

The present invention has been made paying attention to such a point, and an object of the present invention is to mount a contact on a printed wiring board by reflow soldering or the like, and one-touch by pressing a receiver or the like. With the connector, you can press the terminal to the contact with the contact and secure the quality of the receiver, etc. To provide.

In this case, when the receiver or the like is attached to the connector for use, the relative position of the contact and the terminal may be displaced due to the vibration of the receiver or the like, and the contact may be damaged.
Therefore, with respect to this problem, further, by providing a plurality of contact portions that are individually pressed against the terminal, it is possible to prevent contact failure between the contact and the terminal due to displacement of the relative position, and to reduce play in the circumferential direction of the receiver and the like. This is intended to prevent contact failure between the contact and the terminal due to the displacement of the relative position.

Another object is to improve the mounting strength of the connector on the printed wiring board by devising the arrangement of contacts in the connector.

[0010]

In order to achieve the above object, a connector for a receiver or the like according to claim 1 is for electrically and mechanically connecting a receiver or the like having terminals on the back side to a printed wiring board on the back side. A connector having a housing formed of an insulating material, a holder fixed to the housing, having a vertical wall that rises from the peripheral edge to the front side and is in pressure contact with a side wall of the receiver, etc. And a contact having a leg portion which is led out to the rear side of the housing and soldered to the terminal of the receiver, and at least the contact point of the contact and a supporting portion which elastically supports the contact point of each of the receivers and the like. It is characterized in that a plurality of terminals are provided.

This connector is mounted on the printed wiring board by reflow soldering the legs of the contacts to the conductor of the printed wiring board or the like. Then, when the receiver etc. is pushed into the holder, the vertical wall of the holder expands to receive the receiver etc., presses it against the side wall of the receiver etc. and the terminal of the receiver etc. presses against the contact point of the contact, which causes the receiver etc. to print. Electrically and mechanically connected to the wiring board.
In that case, mounting the contact on the printed wiring board and pushing it into the holder such as the receiver is a simple process.
Since automation is possible, cost is reduced and mass production of products is promoted. Further, since there is no member that easily deforms unlike the conventional spring member, the connection performance with the printed wiring board such as the receiver can be stably obtained. Moreover, if the dimensions of the contact itself and the mounting of the contact on the printed wiring board are surely performed, the connection performance with the printed wiring board such as the receiver can be stably obtained.

Further, even if the relative positions of the contacts and the terminals are slightly displaced due to vibration, since there are a plurality of contact points of the contacts that individually press-contact each terminal, the contact rate of one of the terminals is high, and the contact rate is high. The contact failure between the terminal and the terminal is prevented, and the reliability of the contact is improved.

The connector such as the receiver of claim 2 is claimed as
In the connector such as the receiver of paragraph 1, the contact is
Pressed into housing or contact is
Built in by being molded at the same time as the housing
It

This allows the contact housing to
The wearing form of was illustrated.

According to a third aspect of the present invention, there is provided a connector such as a receiver for electrically and mechanically connecting a receiver or the like having terminals on the back side to a printed wiring board on the back side.
A housing formed of an insulating material, a holder fixed to the housing, having a vertical wall that rises from the peripheral edge to the front side and is in pressure contact with a side wall of a receiver, etc., and a contact provided in the housing and in pressure contact with a terminal of the receiver, etc. And a contact having a leg portion led out to the back side of the housing, and fitting to the housing or the holder so as to restrict the receiver from rotating along the vertical wall of the holder. It is characterized by the provision of a section.

This connector is mounted on the printed wiring board by reflow soldering the legs of the contacts to the conductor of the printed wiring board. Then, when the receiver etc. is pushed into the holder, the vertical wall of the holder expands to receive the receiver etc., presses it against the side wall of the receiver etc. and the terminal of the receiver etc. presses against the contact point of the contact, which causes the receiver etc. to print. Electrically and mechanically connected to the wiring board.
In that case, mounting the contact on the printed wiring board and pushing it into the holder such as the receiver is a simple process.
Since automation is possible, cost is reduced and mass production of products is promoted. Further, since there is no member that easily deforms unlike the conventional spring member, the connection performance with the printed wiring board such as the receiver can be stably obtained. Moreover, if the dimensions of the contact itself and the mounting of the contact on the printed wiring board are surely performed, the connection performance with the printed wiring board such as the receiver can be stably obtained.

Further, even if the receiver or the like rotates along the vertical wall of the holder due to vibration and the relative positions of the contact and the terminal are slightly displaced, the fitting portion fits with the receiver or the like and the above-described rotation is restricted. The contact between the contact and the terminal is maintained, contact failure is prevented, and the reliability of the contact is improved. In that case, compared to providing a fitting part on the vertical wall of the holder, it is possible to easily correct the position so that the receiver etc. can be fitted and rotated before pushing the receiver etc. into the holder. Is excellent.

A connector such as a receiver according to a fourth aspect has the structure according to any one of the first to third aspects, in which the outer end of the leg portion of the contact is substantially point-symmetrical with respect to the central portion of the housing in plan view. It is led to the side of the housing so as to have a positional relationship.

In this way, since the line connecting the outer ends of the legs passes through the central part of the housing, the bending stress and the like applied to the legs at the time of pushing into and pulling out from the holder such as the receiver is minimized. It can be suppressed.

[0020]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a connector such as a receiver according to the embodiment. The receiver and the like illustrated here are dynamic type receivers (speakers) incorporated in, for example, mobile phones. As shown in FIG. 4, the receiver or the like 50 is formed in a substantially disc shape, and has terminals 51, 51 on the back surface. Then, on the side wall 52 of the receiver or the like 50, two protrusions 53, 53 are formed at positions substantially opposite to each other in plan view as shown in FIG. 4B.

The connector of this embodiment has a housing 1
0, a holder 20 fixed to the housing 10,
The housing 10 is provided with contacts 31 and 32 provided respectively corresponding to the two terminals 51 and 51 of the receiver 50.

The housing 10 is made of an insulating material such as heat resistant resin, and is formed in an annular shape.
The holder 20 is formed by drawing a thin metal plate, such as phosphor bronze, which can be soldered, and corresponds to the back side of the housing 10 (downward in FIG. 2A). ), And a vertical wall 22 that rises from the peripheral edge of the substrate 21 to the front side (corresponding to the upper side in FIG. 2A) and presses against the side wall 52 of the receiver 50. There is. Substrate 2 of holder 20
A through hole 23 is formed in the holder 1. The holder 20 is fixed to the housing 10 by fitting the rivet portion 11 formed on the rear surface of the housing 10 into the through hole 23. There are two vertical walls 22 of the holder 20, and the substrate 21
It stands up at two locations that are almost opposite to each other on the peripheral edge of. And the window portion 24 is opened in the vertical wall 22,
This facilitates elastic deformation of the vertical wall 22, and
The projection 53 of the receiver 50 is received. In this case, the window portion 24 is formed to be sufficiently large vertically and horizontally with respect to the protrusion 53. The vertical wall 22 is inclined inward from the rear surface side toward the front surface side to enhance the elastic restoring force when expanded. Further, the front end of the vertical wall 22 is inclined outward so that the receiver 50 can be easily received when it is pushed in. Further, the substrate 21 is formed with ribs 25 projecting to the back side. The contacts 31 and 32 are formed by punching out a thin metal plate, such as phosphor bronze, which can be soldered. The contacts 31 and 32 are press-fitted into the housing 10 as shown in FIG. , 32a protrudes to the front side of the housing 10 and the terminals 51 of the receiver 50,
It is designed to come into pressure contact with 51, and the leg portions 31b, 3
2b is led out to the back side of the housing 10. Further, a recess 12 is formed on the inner edge of the housing 10 so as to ensure a space between the housing 10 and the back surface of the receiver 50.

At least the contacts 31a, 32a of the contacts 31, 32 and the supporting portion 3 for elastically supporting the contacts 31a, 32a.
A plurality of 1c and 32c are provided for each terminal 51 of the receiver 50. This is the upper contact 31
In this embodiment, a plurality of completely independent contacts 31 are provided, and the number is two.
In that case, the number may be three or more. Instead of providing a plurality of independent contacts 31 as described above, a plurality of support portions 31c and 31c may be branched from one leg portion 31b, and a contact point 31a may be provided on each support portion 31c. In short, the contact point 31a corresponds to the corresponding support portion 31.
It may be configured to be elastically supported individually by c and elastically deformed individually. When a plurality of supporting portions 31c are branched from one leg portion 31b, the contact 31
There is an advantage that the step of press-fitting into the housing 10 is completed in one step, and the contact surfaces of the legs 31b to the printed wiring board P are flush with each other in the contact 31, so that so-called coplanarity can be stably obtained. The above description is exactly the same for the lower contact 32.

The housing 10 includes a receiver 50 and the like.
There is provided a fitting portion 14 which is fitted to the receiver 50 to restrict the receiver 50 from rotating along the vertical wall 22 of the holder 20.
That is, as shown in FIG. 1 to FIG. 3 and FIG. 6, a fitting portion 14 formed of a protrusion rising to the front side is formed on the peripheral portion of the housing 10, and a fitting portion formed of a hole is formed on the back surface of the receiver 50. 54 is formed to be recessed, and when the receiver 50 or the like is pushed into the holder 20, the fitting portion 14 of the housing 10 is fitted to the fitting portion 54 of the receiver 50. Here, further, the housing 10 around the fitting portion 14 is formed to be recessed, and the receiver 50 or the like around the fitting portion 54 is formed to project, and the receiver 50 or the like is projected to the recess forming portion of the housing 10. Although the forming portions are fitted to each other, it is arbitrary whether or not this configuration is adopted. Contrary to the example illustrated in this embodiment, the receiver 50 or the like is formed with a fitting portion formed of a protrusion rising to the back side, and the housing 10 is formed by recessing a fitting portion formed of a hole. Or a combination of these. Further, the shapes and numbers of the fitting portions 14 and 54 are not limited, and when the receiver 50 or the like is pushed into the holder 20, they are fitted and the receiver 50 or the like can rotate along the vertical wall 22 of the holder 20. Anything can be regulated. Further, the fitting portion 14 may be provided on the substrate 21 of the holder 20. Further, if the tip of the fitting portion 14 is chamfered, it functions as a guide when fitting into the fitting portion 54 of the receiver or the like 50, which improves workability.

As shown in FIG. 1, the contacts 31,
The outer ends of the leg portions 31b and 32b of 32 are led out to the side of the housing 10 so as to have a substantially point-symmetrical positional relationship with respect to the central portion of the housing in a plan view. That is, in plan view, the contacts 31a, 32a of the contacts 31, 32
Are arranged on the peripheral edge of the housing so as to face each other with the central part of the housing in between, and the outer ends of the legs 31b of the upper contact 31 extend to the right so that the distance from the central part of the housing gradually increases. The outer end of the leg portion 32b of the lower contact 32 also extends to the left so that the distance from the central portion of the housing gradually increases.

Therefore, the connector of the above embodiment is mounted on the printed wiring board P by reflow soldering the legs 31b and 32b of the contacts 31 and 32 to the conductors of the printed wiring board P. Then, in the next step, the receiver etc. 5
When 0 is pushed into the holder 20, the vertical wall 22 of the holder 20 expands to receive the receiver 50 or the like, press-contacts with the side wall 52 of the receiver 50, and the terminal 51 of the receiver 50,
51 press-contacts the contact points 31a and 32a of the contacts 31 and 32, whereby the receiver or the like 50 is electrically and mechanically connected to the printed wiring board P with one touch. In that case, mounting the contacts 31 and 32 on the printed wiring board P and pushing the receiver or the like 50 into the holder 20 are simple steps, and automation is possible, so that cost is reduced and mass production of the product is achieved. Is promoted. Further, since there is no member that can be easily deformed unlike the conventional spring member, the connection performance of the receiver 50 or the like with the printed wiring board P can be stably obtained. Moreover, if the dimensions of the contact itself and the mounting of the contact on the printed wiring board P are performed reliably, the connection performance of the receiver 50 or the like with the printed wiring board P can be stably obtained. Therefore, while ensuring the quality of the receiver 50 and the like, automation of the assembling work by simplifying the process, cost reduction, mass production of products, and quality improvement of connection performance can be realized all at once.

Further, since at least the contacts 31a, 32a of the contacts 31, 32 and the supporting portions 31c, 32c for elastically supporting the contacts 31a, 32a are provided for each terminal 51 of the receiver 50, a plurality of contacts 31, 32a are provided by vibration.
Even if the relative positions of 32 and the terminals 51, 51 are slightly deviated from each other, there are a plurality of contacts 31a, 32a individually press-contacting each terminal 51.
The contact ratio of 32a is increased, and contact failure between the terminal 51 and the contacts 31, 32 is prevented.
2. The reliability of 2.

Further, the receiver 50 is fitted in the housing 10 so that the receiver 50 can hold the vertical wall 2 of the holder 20.
Since the fitting portion 14 for restricting rotation along 2 is provided, even if the receiver 50 or the like rotates along the vertical wall 22 due to vibration and the relative positions of the contacts 31, 32 and the terminals 51, 51 are slightly displaced, Since the fitting portion 14 is fitted into the fitting portion 54 of the receiver 50 to restrict the rotation, the terminals 51,
The contact between 51 and the contacts 31a, 32a is maintained, contact failure is prevented, and the reliability of the contacts 31, 32 is improved.
In that case, compared with providing a fitting portion on the vertical wall 22 of the holder 20, the receiver 50 can be fitted along the vertical wall 22 before the receiver 50 is completely pushed into the holder 20. As it can be easily adjusted to the position, it is easy to assemble. Moreover, it is difficult to accurately process an opening or the like as a fitting structure on the vertical wall 22 having a curved surface and formed by drawing or the like. Since the machining can be performed with high precision, the function of regulating the rotation can be made effective.

Further, the legs 31 of the contacts 31, 32 are
Since the outer ends of b and 32b are led out to the side of the housing 10 so as to have a substantially point-symmetrical positional relationship with respect to the central part of the housing in plan view, the line connecting the outer ends of the leg portions 31b and 32b is the housing. I will pass through the central part. for that reason,
Bending stress or the like applied to the leg portions 31b and 32b when the receiver 50 or the like is pushed into or pulled out of the holder 20 can be minimized, and connection failure due to damage to the contacts 31 or 32 or solder can be effectively prevented. it can.

Moreover, such arrangement of the outer ends of the leg portions 31b and 32b may be advantageous for noise suppression. That is, FIG. 7 shows an example in which the connector is mounted on the printed wiring board P built in the mobile phone T. However, since the receiver or the like is placed on the ear, the connector is substantially centered in the width direction at one longitudinal end of the printed wiring board P. It will be implemented in the vicinity. In that case, since the antenna A is mounted near the connector in the layout, the antenna A and the leg portion 31b,
There is a high risk that noise will be exchanged with 32b. At that time, as shown in FIG.
The housing 10 is arranged such that the outer end of 2'b is in a position substantially symmetrical with respect to a line passing through the central portion of the housing in plan view.
In the comparative example derived laterally, the outer end of the leg portion 31′b of the upper contact becomes closer to the antenna A and the risk of noise transfer increases, but as in the connector according to the above-described embodiment, the leg portion is not formed. When the outer ends of 31b and 32b are led out to the side of the housing 10 so as to have a substantially point-symmetrical positional relationship with respect to the central part of the housing in a plan view, the outer ends of the leg portions 31b of the upper contacts are sufficiently separated from the antenna A. Therefore, the risk of noise transfer can be greatly reduced.

Here, the material of the holder 20 is not particularly limited, and the present invention includes an embodiment in which the holder 20 is formed of, for example, a resin, and even in such a case, the above-described action and effect can be obtained. When the holder 20 is formed of a solderable metal as in the above-described embodiment, since the metal has a larger elastic coefficient than, for example, a resin, the vertical wall 22 of the holder 20 has the side wall 52 of the receiver 50.
It strongly presses against, and the connecting force of the receiver 50 to the connector becomes strong. If the holder 20 is soldered to the printed wiring board P at the ribs 25, for example, the connecting force of the connector to the printed wiring board P becomes stronger.

The present invention also includes an embodiment in which the vertical wall 22 of the holder 20 and the side wall 52 of the receiver 50 are not provided with any engaging relationship, and even in such a case, the receiver 50 is held on the vertical wall 22 by the pressure contact force. However, when the window portion 24 that loosely fits into the side wall 52 of the receiver or the like 50 is formed in the vertical wall 22 as in the above embodiment, it is possible to reliably prevent the receiver or the like 50 from coming off the connector.

Further, the present invention includes an embodiment in which the housing 10 and the holder 20 are brought into close contact with the rear surface of the receiver or the like 50.
2, when a space is formed between the back surface of the receiver 50 and the like, for example, the back pressure of the receiver 50 is reduced, so that the operation of the receiver 50 is smooth and the sound quality is improved. Is obtained.

In addition, the substrate 2 of the holder 20 is used in the embodiment.
1 is arranged on the back side of the housing 10, the substrate 21
The shape of the holder can be formed into a substantially flat shape, and the holder 2
0 drawing becomes easy.

The above embodiment is merely an example, and the present invention is not limited to this. For example,
The fixing of the holder 20 to the housing 10 is not limited to riveting, but may be, for example, screwing or simultaneous molding. Although the vertical wall 22 of the holder 20 is two in number, it may be three or more, and conversely may be formed in series in the circumferential direction of the peripheral edge of the substrate 21 without being divided into two or more. The vertical wall 22 is formed by inclining from the rear surface side to the front surface inward and outward, but includes an embodiment in which this is not done. Board 21
It is also optional to form the ribs 25 on the. Contact 3
The material of 1, 32 may be any metal that can be soldered,
In addition to press-fitting into the housing 10, the housing 10

The present invention also includes an embodiment in which no space is formed between the receiver and the back surface of the receiver 50. The present invention is an embodiment in which only a part of the holder 20, such as a part of the substrate 21 or the vertical wall 22, is arranged on the back side of the housing 10, and a part of the holder 20 projects to the side of the housing 10. Morphology, including embodiments where the entire holder is located on the front side of the housing 10. The housing 10 does not have to be annular, but may be simply flat. In addition, the holder 20 is the substrate 21.
May not be provided, and only the vertical wall 22 may be provided. As a configuration in which the vertical wall 22 is loosely fitted to the side wall 52 of the receiver 50 or the like, the window 24 may be formed in the vertical wall 22 and the projection 53 may be formed in the side wall 52 of the receiver 50 as in the above embodiment. For example, a protrusion may be formed on the vertical wall 22 and a recess may be formed on the side wall 52 of the receiver 50, or these may be combined. Further, it also includes an embodiment in which the window and the projection are not provided at all on the side walls of the vertical wall and the receiver. In addition to the receiver (speaker), the receiver and the like include devices exemplified by a microphone and a vibrator.
