Embodiment 1 FIG.
1 is a perspective view showing an ultrasonic diagnostic apparatus for hand carry according to Embodiment 1 of the present invention. In the figure, the ultrasonic diagnostic apparatus has an ultrasonic diagnostic apparatus main body 1 and a plurality of types (only one type is shown in the figure) of ultrasonic probes 2 having different sizes and shapes. The ultrasonic probe 2 is selectively connected to the ultrasonic diagnostic apparatus main body 1 according to the diagnostic part.

  The ultrasonic probe 2 includes a probe head 3 that makes contact with a living body to transmit and receive ultrasonic waves, an ultrasonic probe connector 4 that is attached to and detached from the main body of the ultrasonic diagnostic apparatus, and the probe head 3 and the ultrasonic head 2. A cable 5 for connecting the acoustic probe connector 4 is provided. The ultrasonic diagnostic apparatus main body 1 is provided with a main body side connector portion 1a to which the ultrasonic probe connector 4 is attached and detached.

  FIG. 2 is an exploded perspective view showing the ultrasonic probe connector 4 of FIG. The plug 6 is attached to and detached from the main body side connector portion 1a. The plug 6 is provided with a large number of connection pins. In addition, the first and second parent substrates 7 and 8 are fixed vertically and electrically connected to the plug 6. The first and second parent substrates 7 and 8 are arranged in parallel to each other. That is, the first and second parent substrates 7 and 8 face each other with a predetermined interval.

  A plurality of first child boards 9 are fitted on and electrically connected to the surface of the first mother board 7 opposite to the second mother board 8. A plurality of second child boards 10 are fitted and electrically connected to the surface of the second mother board 8 opposite to the first mother board 7.

  The cable 5 includes a number (for example, 100 to 200) of wirings 11 according to the number of channels. These wirings 11 are distributed and connected to the corresponding sub boards 9 and 10 in the ultrasonic probe connector 4.

  A substrate fixing component 12 that covers the parent substrates 7 and 8 and the child substrates 9 and 10 is fixed to the plug 6. The board fixing component 12 sandwiches the first mother board 7 and the first child board 9 to prevent the first child board 9 from falling off the first mother board 7. In addition, the board fixing component 12 sandwiches the second mother board 8 and the second child board 10 to prevent the second child board 10 from falling off the second mother board 8. Furthermore, the board fixing component 12 prevents the parent boards 7 and 8 from being detached from the plug 6 by pressing the upper ends of the mother boards 7 and 8. The upper ends of the parent substrates 7 and 8 are the other end (the opposite end portion) of the connection portion of the plug 6.

  A housing 13 that covers the board fixing component 12 is fixed to the plug 6. The housing 13 is provided with a circular opening 13a through which the cable 5 is drawn. The housing 13 is divided into left and right divided pieces 13b and 13c so that the opening 13a is divided into two in a semicircular shape.

  The divided pieces 13b and 13c are fixed to the side surfaces of the plug 6 by a plurality of screws 14, respectively. By fixing the divided pieces 13 b and 13 c to the plug 6, the divided pieces 13 b and 13 c are combined to form the housing 13. The board fixing component 12 is fastened together with the divided pieces 13b and 13c by screws 14 and fixed to the plug 6.

  A cable bushing 15 is fixed to and integrated with the lead-out portion of the cable 5 from the housing 13. The cable bushing 15 is fixed inside the opening 13a by combining the split pieces 13b and 13c.

  3 is a side view of the ultrasonic probe connector 4 shown in FIG. 1 with one divided piece 13b removed, and FIG. 4 is a cross-sectional view of the ultrasonic probe connector 4 shown in FIG. It corresponds to a cross section along line IV. The board fixing component 12 includes a first inner board 12 a sandwiching the first daughter board 9 between the first mother board 7 and a second daughter board 10 sandwiched between the second mother board 8 and the first inner board 12 a. 2 and an interval holding portion (projecting portion) 12c that is interposed between the first and second parent substrates 7 and 8 and holds the interval between the first and second parent substrates 7 and 8. ing.

  By configuring the substrate fixing component 12 with a material having a higher electromagnetic shielding property than the housing 13, noise resistance to the plug 6, the parent substrates 7 and 8, and the child substrates 9 and 10 can be improved. Further, by using a material having high thermal conductivity for the substrate fixing component 12, a structure with good heat dissipation can be obtained. By using, for example, aluminum as a material excellent in electromagnetic shielding properties and thermal conductivity, the workability is good and the structure is light.

  5 is an enlarged side view showing the cable bushing 15 of FIG. 2, and FIG. 6 is a perspective view showing the cable bushing 15 of FIG. The cable bushing 15 is provided with a flange-like protrusion 15a protruding outward in the radial direction over the entire circumference. The opening 13a is provided with a retaining groove 13d into which the protrusion 15a is fitted.

  The cross-sectional shape of the protrusion 15a orthogonal to the axial direction of the cable bushing 15 is a pentagon or more polygon. In this example, the cross-sectional shape of the protrusion 15a is an octagon. The cross-sectional shape of the retaining groove 13d orthogonal to the axial direction of the cable bushing 15 is the same as that of the protrusion 15a, that is, an octagon.

  By fitting the protruding portion 15a into the retaining groove 13d, the cable bushing 15 is prevented from rotating and the movement in the axial direction is prevented, and the strength against pulling and pushing of the cable 5 is ensured.

  FIG. 7 is an explanatory diagram showing the difference between the case where the cross-sectional shape of the protrusion 15a is an octagon and the case where the protrusion 15a is a quadrangle (square). When the housing 13 is small and rounded, if the cable bushing 15 is octagonal, it can be easily housed inside the housing 13. However, when the cable bushing 15 is a quadrangle, the outer area is larger by the dot regions 16 a to 16 d than when the cable bushing 15 is an octagon, and the cable bushing 15 cannot be stored in the same housing 13.

  If the cross-sectional shape of the protrusion 15a is a quadrangle, the angle adjustment in the rotation direction of the cable bushing 15 for adjusting the position of the child boards 9 and 10 relative to the parent boards 7 and 8 can be performed only 90 degrees. On the other hand, by making the cross-sectional shape of the protrusion 15a an octagon, the angle adjustment of the cable bushing 15 is easy and the assemblability is improved.

  In such an ultrasonic probe connector 4, the mother substrates 7 and 8 and the child substrates 9 and 10 are sandwiched by the substrate fixing component 12, and the child substrates 9 and 10 are prevented from falling off from the mother substrates 7 and 8. Therefore, it is possible to reduce the overall size while firmly holding the built-in components and preventing disconnection.

  In addition, since the board fixing component 12 prevents the parent boards 7 and 8 from falling off the plug 6, the built-in parts can be firmly held with a small number of parts.

  Furthermore, since the board fixing component 12 is provided with the first and second inner surfaces 12a and 12b and the interval holding portion 12c, the number of parts can be reduced from the parent boards 7 and 8 of the child boards 9 and 10. And the wobbling of the two parent substrates 7 and 8 can be prevented.

  Furthermore, the protrusion 15a is provided in the cable bushing 15, the retaining groove 13d is provided in the opening 13a, and the cross-sectional shape of the protrusion 15a is a pentagon or more polygon, so that the fitting surface with the housing 13 increases. While securing a flat area necessary for preventing rotation, the axial length of the surface serving as the rotation preventing function can be shortened. Further, the cable bushing 15 can be prevented from moving in the axial direction with a compact structure, and the strength against pulling and pushing of the cable 5 can be ensured. Therefore, this also makes it possible to reduce the overall size while firmly holding the built-in components and preventing disconnection.

  In the above description, the board fixing component 12 and the housing 13 are configured separately. However, the board fixing component 12 and the housing 13 are integrally formed so that the housing 13 has the function of the board fixing component 12. Also good. In other words, the housing 13 may also serve as a board fixing component.

In this case, the structure of the board fixing component 12 shown in FIGS. Specifically, the housing 13 has a second child substrate 10 between the first inner surface 12 a sandwiching the first child substrate 9 between the first mother substrate 7 and the second mother substrate 8. A second inner surface 12b that sandwiches the first and second mother substrates 7 and 8, and an interval holding portion (projecting portion) 12c that holds the interval between the first and second mother substrates 7 and 8. have.
Therefore, the housing 13 can sandwich the first mother board 7 and the second child board 9 and can sandwich the second mother board 8 and the second child board 10. Further, the housing 13 can press the upper ends of the parent substrates 7 and 8.

Embodiment 2. FIG.
Next, FIG. 8 is a perspective view showing a cable bushing 21 of the ultrasonic probe connector 4 according to Embodiment 2 of the present invention. The cable bushing 21 of the second embodiment is provided with a polygonal pyramidal projection 21a. In this example, the protrusion 21a has an octagonal pyramid shape. Other configurations are the same as those in the first embodiment.

  When the cable 5 is pulled, stress concentrates at the base of the protrusion 21a. On the other hand, the stress at the time of tension | pulling of the cable 5 can be disperse | distributed by making the projection part 21a into an octagonal pyramid shape.

As long as the rotation of the cable bushing can be prevented, the cross-sectional shape of the retaining groove and the cross-sectional shape of the protrusion may not be completely the same.
Further, the number of parent substrates may be one or three or more. Accordingly, the number of child boards is not particularly limited.
Further, the board fixing component may be divided into a plurality of parts and fixed to the plugs.
