Description

Coaxial connector

The present invention relates to a coaxial connector, and more particularly to a coaxial connector that is incorporated in a mobile communication device such as a mobile phone and switches a signal path.

As an invention related to a conventional coaxial connector, for example, a coaxial connector with a switch described in Patent Document 1 is known. FIG. 10 is an exploded perspective view of a coaxial connector 500 with a switch described in Patent Document 1. FIG.

The coaxial connector 500 with a switch includes an insulating substrate 502,

fixed terminals

504 and 506, an elastic body 508, a movable terminal 510, and an external terminal 512. The insulating substrate 502 has a rectangular shape. The four fixed terminals 504 are provided so as to be arranged along one long side of the insulating substrate 502. The four fixed terminals 506 are provided along the other long side of the insulating substrate 502.

The elastic body 508 is placed on the insulating substrate 502. Each of the four movable terminals 510 is provided on the elastic body 508 and connects the fixed terminal 504 and the fixed terminal 506. The external terminal 512 is provided with a long hole and is placed on the elastic body 508. The movable terminal 510 is exposed to the outside through a long hole.

In the coaxial connector 500 with a switch as described above, the movable terminal 510 normally connects the fixed terminal 504 and the fixed terminal 506. When the movable terminal 510 is pushed down by a center contact (not shown), the elastic body 508 is deformed and the movable terminal 510 is separated from the fixed terminal 504. Thereby, the connection between the fixed terminal 504 and the fixed terminal 506 is disconnected, the center contact and the fixed terminal 506 are connected, and the signal path is switched.

Incidentally, the coaxial connector 500 with a switch described in Patent Document 1 has a problem that it is difficult to switch each signal path independently. More specifically, the plurality of movable terminals 510 are provided on the elastic body 508. Therefore, when any one of the movable terminals 510 is pushed down by the center contact, the elastic body 508 is deformed, and the movable terminal 510 adjacent to the movable terminal 510 is also pushed down. As a result, the movable terminal 510 pushed down by the center contact and the movable terminal 510 adjacent to the movable terminal 510 are separated from the corresponding fixed terminal 504. That is, in addition to the signal path to be switched, the signal path adjacent to the signal path is switched.

Next, the movable terminals 20-1 and 20-2 and the fixed terminals 22-1 and 22-2 will be described with reference to FIGS. FIG. 4 is an external perspective view of the lower case 18 with the movable terminals 20-1 and 20-2 and the fixed terminals 22-1 and 22-2 attached thereto. FIG. 5 is an external perspective view of the upper case 16 with the movable terminals 20-1 and 20-2 and the fixed terminals 22-1 and 22-2 attached thereto. The movable terminal 20-1 and the movable terminal 20-2 have the same structure. Similarly, the fixed terminal 22-1 and the fixed terminal 22-2 have the same structure. Therefore, hereinafter, the movable terminal 20-1 and the fixed terminal 20-2 will be described.

The fixed terminal 22-1 is formed by punching and bending a flat metal plate. As shown in FIGS. 2 and 3, the fixed portion 48-1, the lead portion 49-1, and the contact portion 50a- 1, 50b-1. The fixing portion 48-1 is a flat portion that is fixed to the main body 12 by being sandwiched between the fixing surface 39-1 and the fixing surface 58-1 when the coaxial connector 10 is assembled. The lead part 49-1 is connected to the positive side in the x-axis direction of the fixed part 48-1, and is formed by bending into an L shape. As shown in FIGS. 1 and 4, the lead portion 49-1 is exposed to the outside of the main body 12 from the notch portion 55-1 when the coaxial connector 10 is assembled. As shown in FIGS. 4 and 5, the contact portions 50a-1 and 50b-1 are respectively connected to the positive side in the y-axis direction and the negative direction from the end portion on the negative direction side in the x-axis direction of the fixed portion 48-1. And is bent to the positive side in the z-axis direction with respect to the fixed portion 48-1. The contact portions 50a-1 and 50b-1 are in contact with the movable terminal 20-1 at a portion facing the negative direction side in the z-axis direction. Two contact portions 50a-1 and 50b-1 are provided so as to correspond to branch portions 44a-1 and 44b-1, which will be described later. Further, a broken line between the contact portions 50a-1 and 50b-1 and the fixed portion 48-1 is parallel to the x-axis direction.

The movable terminal 20-1 is formed by punching a metal plate having a spring property into a predetermined shape and bending it. As shown in FIGS. 2 and 3, the fixed portion 42-1 and the lead portion 43-1 are formed. And a leaf spring portion 44-1. The fixing portion 42-1 is a flat portion that is fixed to the main body 12 by being sandwiched between the fixing surface 37-1 and the fixing surface 57-1 when the coaxial connector 10 is assembled. The lead portion 43-1 is connected to the negative direction side of the fixed portion 42-1 in the x-axis direction, and is formed by bending into an L shape. As shown in FIGS. 1 and 4, the lead part 43-1 is exposed to the outside of the main body 12 from the notch part 54-1 when the coaxial connector 10 is assembled.

As shown in FIG. 4, the leaf spring portion 44-1 extends linearly in the x-axis direction from the fixed portion 42-1 to the fixed terminal 22-1, and the contact portion of the fixed terminal 22-1 50a-1 and 50b-1 are in contact with the lower case 18 at their tips ta and tb. More specifically, the leaf spring portion 44-1 has branch portions 44a-1 and 44b-1 that are formed by branching into two on the tip end ta and tb side (the positive direction side in the x-axis direction). ing. The fixed terminal 22-1 is located between the branch portions 44a-1 and 44b-1, and the contact portions 50a-1 and 50b-1 of the fixed terminal 22-1 are respectively viewed in plan from the z-axis direction. It spreads in the y-axis direction as it goes in the positive direction in the x-axis direction so as to overlap the branch portions 44a-1 and 44b-1. Further, the leaf spring portion 44-1 is curved so that the central portion in the x-axis direction protrudes to the positive direction side in the z-axis direction. Therefore, the branch portions 44a-1 and 44b-1 are in pressure contact with the contact portions 50a-1 and 50b-1, respectively, by the urging force of the leaf spring portion 44-1. That is, the leaf spring portion 44-1 is pressed against the negative direction side in the z-axis direction by the fixed terminal 22-1. Thereby, the movable terminal 20-1 and the fixed terminal 22-1 are electrically connected.

The movable terminal 20-1 and the movable terminal 20-2 are separated from each other and are not in contact with each other. Therefore, the force applied to the movable terminal 20-1 is not transmitted to the movable terminal 20-2, and the force applied to the movable terminal 20-2 is not transmitted to the movable terminal 20-1. Similarly, the fixed terminal 22-1 and the fixed terminal 22-2 are separated from each other and are not in contact with each other.

As shown in FIG. 5, the movable terminal 20-1 and the fixed terminal 22-1 configured as described above are configured such that, first, after the fixed terminal 22-1 is attached to the upper case 16, the movable terminal 20-1 is not attached. It is attached to the upper case 16. As a result, the portions on the positive side in the z-axis direction of the branch portions 44a-1 and 44b-1 and the portions on the negative direction side in the z-axis direction of the contact portions 50a-1 and 50b-1 come into contact.

The external terminal 14 is in contact with the outer conductor of the counterpart coaxial connector, is formed by punching a metal plate of phosphor bronze (for example, C5191), bending, drawing, etc. As shown in FIG. 1 and FIG. 31, a cylindrical portion 32, and leg portions 33a to 33f.

The flat part 31 is a plate-like member and covers the upper case 16 from the positive direction side in the z-axis direction.

Leg portions

33c and 33d are provided at both ends of the short side located on the negative side of the flat portion 31 in the y-axis direction. Legs 33a and 33b are provided at both ends of the short side located on the positive side of the flat portion 31 in the y-axis direction. A leg portion 33f is provided at the center of the long side located on the positive side of the flat portion 31 in the x-axis direction. A leg 33e is provided at the center of the long side located on the negative side of the flat portion 31 in the x-axis direction. The leg portions 33a to 33f are formed by bending a part of a plate-like body extending from the flat portion 31, and sandwich and fix the upper case 16 and the lower case 18 as shown in FIG. Furthermore, a cylindrical portion 32 that protrudes toward the positive side in the z-axis direction is provided at the center of the flat portion 31. The cylindrical portion 32 has the same shape (oval shape) as that of the cylindrical portion 34 when viewed in plan from the z-axis direction, and is fitted to the outer conductor of the counterpart coaxial connector. Thereby, the cylindrical portion 34 surrounds the holes 34a-1 and 34a-2 when viewed in plan from the z-axis direction. The external terminal 14 is normally kept at a ground potential. The outer surface of the external terminal 14 is plated as necessary.

The coaxial connector 10 configured as described above is assembled as follows. As shown in FIG. 5, the fixed terminals 22-1 and 22-2 are aligned and attached to the upper case 16, and then the movable terminals 20-1 and 20-2 are aligned and attached to the upper case 16. In FIG. 5, the leg portions 33a to 33f are bent, but actually the leg portions 33a to 33f are not bent at this stage.

Next, as shown in FIG. 5, the external terminal 14 is attached to the upper case 16 from the positive direction side in the z-axis direction. At this time, the cylindrical portion 34 is inserted into the cylindrical portion 32. Thereafter, as shown in FIG. 3, the lower case 18 is stacked on the upper case 16 from the negative direction side in the z-axis direction.

Finally, the legs 33a to 33f of the external terminal 14 are caulked to obtain the coaxial connector 10 having the structure shown in FIG.

Next, the operation of the coaxial connector 10 will be described with reference to FIGS. FIG. 6 is a cross-sectional structure diagram in the xz plane of the coaxial connector 10 when the counterpart coaxial connector is not attached. FIG. 7 is a cross-sectional structure diagram in the xz plane of the coaxial connector 10 when the counterpart coaxial connector is attached. The movable terminal 20-1 and the movable terminal 20-2 have the same structure. Similarly, the fixed terminal 22-1 and the fixed terminal 22-2 have the same structure. Therefore, hereinafter, operations of the movable terminal 20-1 and the fixed terminal 22-1 will be described.

As shown in FIG. 6, when the counterpart coaxial connector is not attached, the movable terminal 20-1 is in a state where the central portion in the x-axis direction swells to the positive side in the z-axis direction. Accordingly, the branch portions 44a-1 and 44b-1 (only the branch portion 44a-1 is shown in FIG. 6) are connected to the contact portions 50a-1 and 50b-1 (only the contact portion 50a-1 is shown in FIG. 6). The movable terminal 20-1 and the fixed terminal 22-1 are electrically connected by being pressed by the urging force of the leaf spring portion 44-1.

On the other hand, when the counterpart coaxial connector is attached, the probe 130 of the counterpart coaxial connector is inserted from the positive direction side in the z-axis direction to the negative direction side through the hole 34a-1. As a result, the probe 130 contacts the leaf spring portion 44-1 and pushes the leaf spring portion 44-1 downward toward the negative side in the z-axis direction. That is, the leaf spring portion 44-1 is displaced to the negative side in the z-axis direction by the probe 130. As a result, as shown in FIG. 7, the branch portions 44a-1 and 44b-1 of the leaf spring portion 44-1 are separated from the contact portions 50a-1 and 50b-1, and the movable terminal 20-1 and the fixed terminal 22- are separated. 1 is disconnected, and the probe 130 and the movable terminal 20-1 are electrically connected. At the same time, the outer conductor (not shown) of the counterpart coaxial connector is fitted into the external terminal 14, and the outer conductor is also electrically connected to the external terminal 14.

Further, when the counterpart coaxial connector is removed from the coaxial connector 10, the central portion of the leaf spring portion 44-1 in the x-axis direction returns to the positive direction side in the z-axis direction as shown in FIG. Accordingly, the movable terminal 20-1 and the fixed terminal 22-1 are electrically connected again, while the electrical connection between the probe 130 and the movable terminal 20-1 is broken.

(effect)
According to the coaxial connector 10 configured as described above, a plurality of signal paths can be switched independently. More specifically, in the coaxial connector 10, two sets of fixed terminals 20-1 and 20-2 and movable terminals 22-1 and 22-2 are provided so as to correspond to the two holes 34a-1 and 34a-2. It has been. The movable terminals 22-1 and 22-2 are separated from each other. Therefore, even if the movable terminal 22-1 is pushed by the probe 130, the force by which the probe 130 pushes the movable terminal 22-1 is not transmitted to the movable terminal 22-2. Therefore, when the movable terminal 22-1 is pushed by the probe 130, the movable terminal 22-2 is not separated from the fixed terminal 20-2. Similarly, even if the movable terminal 22-2 is pushed by the probe 130, the force by which the probe 130 pushes the movable terminal 22-2 is not transmitted to the movable terminal 22-1. Therefore, when the movable terminal 22-2 is pushed by the probe 130, the movable terminal 22-1 does not move away from the fixed terminal 20-1. As a result, according to the coaxial connector 10, switching of a plurality of signal paths is performed independently.

Further, according to the coaxial connector 10, two sets of movable terminals 20-1 and 20-2 and fixed terminals 22-1 and 22-2 are provided on one main body 12. Therefore, the mounting area of the coaxial connector 10 is smaller than the mounting area of the two coaxial connectors having one set of fixed terminal and movable terminal. Furthermore, according to the coaxial connector 10, the number of parts is reduced as compared with two coaxial connectors each provided with one set of fixed terminal and movable terminal.

Further, according to the coaxial connector 10, two sets of movable terminals 20-1 and 20-2 and fixed terminals 22-1 and 22-2 are provided on one main body 12. Therefore, only one cylindrical part 32 is sufficient. As a result, when the coaxial connector 10 is manufactured, only one place for drawing processing for manufacturing the cylindrical portion 32 is required. As a result, the coaxial connector 10 can be easily manufactured. Further, only one portion of the cylindrical portion 32 is fitted with the outer conductor of the counterpart coaxial connector. As a result, the coaxial connector 10 can be easily designed.

Further, according to the coaxial connector 10, the leg portion 33e is located between the lead portions 43-1 and 43-2 as shown in FIG. 1 (b). Further, the end portion of the leg portion 33e on the positive side in the x-axis direction is located on the positive side in the x-axis direction with respect to the lead portions 43-1 and 43-2. As a result, the lead portions 43-1 and 43-2 do not directly face each other. As a result, the isolation characteristics between the two signal paths are improved.

Further, according to the coaxial connector 10, the leg portion 33f is located between the lead portions 49-1 and 49-2 as shown in FIG. 1 (b). Further, the end portion on the negative side in the x-axis direction of the leg portion 33f is located on the negative direction side in the x-axis direction with respect to the lead portions 49-1 and 49-2. As a result, the lead portions 49-1 and 49-2 do not directly face each other. As a result, the isolation characteristics between the two signal paths are improved.

(First modification)
Below, the coaxial connector 10a which concerns on a 1st modification is demonstrated, referring drawings. FIG. 8 is an external perspective view of the coaxial connector 10a according to the first modification.

The coaxial connector 10a is different from the coaxial connector 10 in that three sets of movable terminals 20-1 to 20-3 and fixed terminals 22-1 to 22-3 are provided.

As described above, the number of sets of the movable terminal 20 and the fixed terminal 22 provided in the coaxial connector 10a may be plural, and may be three or more.

(Second modification)
Below, the coaxial connector 10b which concerns on a 2nd modification is demonstrated, referring drawings. FIG. 9 is an external perspective view of a coaxial connector 10b according to a second modification.

The coaxial connector 10b is different from the coaxial connector 10 in that cylindrical portions 32-1 and 32-2 are provided instead of the cylindrical portion 32. That is, the cylindrical portions 32-1 and 32-2 respectively surround the holes 34a-1 and 34a-2 when viewed in plan from the z-axis direction.

According to the coaxial connector 10b as described above, the cylindrical portions 32-1 and 32-2 exist around the two probes 130 when the probe 130 is inserted into the holes 34a-1 and 34a-2. As a result, the distance between the two probes 130 and the cylindrical portions 32-1 and 32-2 becomes uniform, and the characteristic impedance of the two probes 130 becomes a desired characteristic impedance by making the fitting portion a coaxial structure. It becomes easy to match. Further, noise is radiated from the probe 130 to the outside.

(Other embodiments)
The coaxial connector according to the present invention is not limited to the

coaxial connectors

10, 10a, 10b, and can be changed within the scope of the gist thereof.

As shown in FIG. 1 (b), the lead portions 43-1 and 43-2 are used for connection to the outside, and the shape of the portion (ie, the tip) is used for connection to the outside at 49-1 and 49-2. It is different from the shape of the portion to be formed (ie, the tip). However, these shapes may be the same. In this case, when the coaxial connector 10 is mounted on the circuit board, the force received from the solder by each of the lead portions 43-1, 43-2, 49-1, 49-2 becomes equal. As a result, the coaxial connector 10 is mounted at an accurate position on the circuit board.

The present invention is useful for a coaxial connector, and is particularly excellent in that a plurality of signal paths can be switched independently.
