  However, in such a conventional socket for electric parts, according to Patent Document 1, the latch portion is configured to have a larger rotation amount than the lever portion, so that the upper portion of the housing portion is opened greatly. Although it is described that the electric components can be accommodated and taken out easily, it is not explicitly described that the electric components are positioned in the center of the accommodating portion.

  On the other hand, Patent Document 2 describes that the electric parts are positioned at the center of the accommodating part by the guide parts protruding from the four corners of the accommodating part. However, the accommodating area of the accommodating part is determined by the guide parts. Since it is regulated according to the external dimensions, there is little room in the accommodation area for the external dimensions of the electrical components. Therefore, when the electric component is accommodated in the accommodating portion, the edge of the electric component may ride on the guide portion and scrape a part of the guide portion. Therefore, dust generated by scraping the guide portion may cause poor electrical contact between the terminal portion of the electric component and the contact pin.

  Therefore, an object of the present invention is to provide a socket for an electric component that addresses such a problem and that can ensure a sufficiently large accommodating area in the accommodating portion of the socket body than the electric component. ..

In order to achieve the above-mentioned object, the socket for electrical parts according to the present invention electrically contacts the terminal part of the electrical part housed in the housing part of the socket body and the contact pin provided in the socket body. An electrical component socket, which performs forward and backward advancing and retracting operations in a diagonal direction on the accommodation surface of the accommodating portion having a rectangular shape, and at least one corner of the electrical component accommodated in the accommodating portion during forward movement. Is provided toward the center of the accommodating portion to position the electric component, and the pressing member is provided at the contact portion with the electric component so as to extend in a direction intersecting the forward/backward direction. , A piece having a function of sliding on the accommodation surface and abutting on a side surface of the electrical component to bring the electrical component toward a central portion of the accommodation portion .

  According to the present invention, the pressing member for pressing the electric component to position it in the center of the accommodating portion of the socket main body moves forward and backward in the diagonal direction of the accommodating portion having a rectangular shape, so that the accommodating portion is accommodated. In addition, it is possible to secure a storage area that is sufficiently larger than that of the electrical component. Therefore, there is no possibility that the edge portion of the electric component rides on the guide portion and scrapes a part of the guide portion unlike the conventional technique. Therefore, there is no fear that the electrical contact failure between the terminal portion of the electric component and the contact pin will occur due to the dust generated by scraping the guide portion.

  Further, as shown in FIG. 9, the guide roller 16 has a V-shaped V cut portion 25 in the circumferential direction corresponding to the contact portion with the electric component 5, and the main portion of the housing portion 7 is shown in FIG. As shown in the enlarged plan view, the V-cut surface 25a of the guide roller 16 contacts the intersecting side surface 5a of the electric component 5 housed in the housing portion 7. As a result, the guide roller 16 can apply a uniform pressing force to the electric component 5 toward the center of the housing portion 7. In this case, the guide roller 16 is provided such that the center of the V-cut portion 25 (the apex of the V-cut portion) matches the central axis of the movable portion 15 in the directions of arrows A and B, as shown in FIG. 8A. ..

  The operation member 3 is provided at both ends of the uniaxial direction (in the present embodiment, the X direction) of the two orthogonal axes parallel to the accommodation surface 7a with the accommodation portion 7 of the socket body 1 in between. The operating member 3 causes the pressing member 2 to move forward and backward, presses the upper surface of the electric component 5 toward the accommodation surface 7a when the pressing member 2 moves forward, and releases the pressing when the pressing member 2 moves backward. 26 and a latch portion 27.

  Here, the lever portion 26 is a portion to which an operating force is applied from the outside, and as shown in FIG. 3, both ends of the lever portion 26 are supported by the socket main body portion 1 in parallel to the accommodation surface 7a. It is arranged so as to be rotatable around it. The latch portion 27 is a portion that presses the upper surface of the electric component 5 toward the accommodation surface 7a side, and is opposite to the side of the lever portion 26 to which the operating force is applied with the first rotation shaft 28 interposed. Further, it is arranged rotatably around a second rotation shaft 29 supported by the lever portion 26 in parallel with the accommodation surface 7a. Then, when the lever portion 26 is operated and rotated, the latch portion 27 is rotated in conjunction with this movement. At this time, as shown in the figure, the operation member 3 is configured such that the rotation amount θ2 of the latch portion 27 is larger than the rotation amount θ1 of the lever portion 26.

  In detail, as shown in FIG. 11, the lever portion 26 has a spring receiving hole 30 which is opened downward at a lower portion of one end portion side, and as shown in FIG. The other end of the second spring member (for example, a spring coil) 31 fixed to the main body 1 is received, and the second spring member 31 constantly urges the upper part upward. Further, as shown in FIG. 11, the upper portion on one end side is formed as an operated portion 32 that receives an operating force from the outside. Further, a first shaft hole 33 through which the first rotating shaft 28 is inserted is provided at the lower end on the other end side, and a second shaft hole 34 through which the second rotating shaft 29 is inserted is provided at the upper end on the other end side. Is provided. Further, a transmission hole portion 35 whose lower side is opened is provided in a lower portion of the first shaft hole 33 near one end portion, and a projection portion 40 of an operation force transmission means 4 described later is provided on a side surface 35a of the transmission hole portion 35. By making contact with each other, the rotational movement of the lever portion 26 can be converted into the sliding movement of the operating force transmission means 4.

  Further, as shown in FIG. 12, the latch portion 27 is provided with a third shaft hole 36, through which the second rotation shaft 29 is inserted, in a substantially central portion thereof, and the tip end portion 27 a is placed on the upper surface of the electrical component 5. It is formed as a pressing convex portion 37 that presses to the 7a side. Further, on the rear end portion 27b side of the latch portion 27, a long hole 38 extending obliquely downward from the third shaft hole 36 side is formed, and the shaft portion 43 provided in the socket body portion 1 (see FIG. 15). (See) is to be inserted. As a result, the shaft portion 43 slides in the elongated hole 38 as the lever portion 26 rotates, whereby the latch portion 27 rotates about the second rotation shaft 29.

  An operation force transmission means 4 is provided between the pressing member 2 and the operation member 3. The operating force transmitting means 4 converts the operating force applied to the operating member 3 into an advancing/retreating motion of the pressing member 2 and transmits the operating force to the elongated hole 11 (see FIG. 5) of the socket body 1 as shown in FIG. The third spring member (for example, a spring coil) 39 that is housed constantly urges the housing unit 7 side, and the upper surface of the socket body 1 below the operation member 3 is moved in the X direction in association with the movement of the operation member 3. It is designed to slide in the direction.

  Specifically, as shown in FIG. 13, the operating force transmitting means 4 is a plate-shaped member that is long in the Y direction, and is located at an upper surface position corresponding to the transmitting hole portion 35 provided in the lever portion 26 of the operating member 3. A protrusion 40 (indicated by two protrusions 40 in the figure) is provided by being inserted into the transmission hole 35.

  As shown in FIG. 14, the protrusion 40 has a tip end that is tapered toward the front and has a spherical tip, and the side surface 40 a of the tip end is located on the lever portion 26 of the pressing member 2. It is adapted to be pressed by the side surface 35a of the provided transmission hole 35 on the accommodation portion 7 side. In FIG. 13, reference numeral 41 indicates a pin that holds one end portion of the third spring member 39, and reference numeral 42 indicates a guide elongated hole into which the tip end portion of the transmission pin 22 of the pressing member 2 is inserted and slides.

Next, the operation of the electrical component socket thus configured will be described.
First, when the operated portion 32 of the lever portion 26 of the operating member 3 is given an operating force in the direction of arrow C against the biasing force of the second spring member 31 as shown in FIG. The portion 26 rotates about the first rotation shaft 28. That is, in FIG. 3, the left lever portion 26 rotates counterclockwise, and the right lever portion 26 rotates clockwise.

  With the rotation of the lever portion 26, the shaft portion 43 provided in the socket body portion 1 slides through the long hole 38 (see FIG. 12) provided in the latch portion 27 from the upper end portion to the lower end portion, As a result, the latch portion 27 rotates around the second rotation shaft 29 and stands up as shown by an arrow D. That is, in FIG. 3, the left latch portion 27 rotates counterclockwise and the right latch portion 27 rotates clockwise. In this way, by raising the latch portion 27, the upper part of the housing portion 7 is fully opened, and the electric component 5 can be easily put into the housing portion 7.

  Further, as the lever portion 26 rotates, as shown in FIG. 15A, the tip portion of the protrusion 40 of the operation force transmitting means 4 inserted into the transmission hole portion 35 provided in the lever portion 26 is It is pressed by the side surface 35 a of the transmission hole portion 35 on the accommodation portion 7 side. As a result, the operation force transmission means 4 moves in the direction opposite to the accommodation portion 7 against the biasing force of the third spring member 39. That is, in FIG. 3, the left operating force transmitting means 4 moves leftward (−X direction), and the right operating force transmitting means 4 moves rightward (+X direction).

Here, focusing on the lower left pressing member 2 shown in FIG. 2, its operation will be described.
In FIG. 2, when the left operation force transmission means 4 moves to the left (−X direction), the distal end portion is inserted into the guide elongated hole 42 of the operation force transmission means 4 as shown in FIG. 7. The transmission pin 22 of the pressing member 2 moves in the -X direction by being pushed by the operating force transmission means 4, and at the same time, slides on the side surface of the guide elongated hole 42 and also moves in the -Y direction. As a result, the pressing member 2 retracts to the end of the moving range in the direction of the arrow B shown in FIG. 7 (outward along the substantially diagonal line of the accommodating portion 7). The other three pressing members 2 also move backward. As a result, as shown in FIG. 2, the housing portion 7 is fully opened, and the electrical component 5 can be housed.

  When the housing 7 is opened as described above, the electric component 5 is loaded into the housing 7 from above. In this case, since the housing area of the housing portion 7 in the fully open state is sufficiently larger than the bottom area of the electric component 5, a part of the electric component 5 protrudes from the housing portion 7 and rides on the socket body portion 1 to There is no danger of cutting a part of the. Further, even if the corner of the electric component 5 rides on the pressing member 2 due to the deviation of the loading position, the guide roller 16 of the pressing member 2 rotates and introduces the electric component 5 into the housing portion 7. There is no fear that part of 2 will be scraped. Therefore, it is possible to solve the problem of poor electrical contact between the terminal portion 6 of the electric component 5 and the contact pin 9 due to dust generated by scraping a part of the socket body 1 or the pressing member 2. It is possible to improve the reliability of the performance inspection of item 5.

  When the operating force of the lever portion 26 on the operated portion 32 is released after the electric component 5 is accommodated in the accommodating portion 7 in this manner, the operation opposite to the above is performed. That is, as shown in FIG. 15B, the lever portion 26 is urged upward by the second spring member 31 to rotate about the first rotation shaft 28 in the arrow E direction. Specifically, in FIG. 3, the left lever portion 26 rotates clockwise and the right lever portion 26 rotates counterclockwise.

  With the rotation of the lever portion 26, the shaft portion 43 provided in the socket body portion 1 slides through the elongated hole 38 provided in the latch portion 27 from the lower end portion to the upper end portion, and the latch portion 27 is moved to the first position. 2 Rotate around the rotation shaft 29 in the arrow F direction. That is, in FIG. 3, the left latch portion 27 rotates clockwise and the right latch portion 27 rotates counterclockwise. Then, as shown in FIG. 15B, the latch portion 27 is laid down and the upper surface of the electric component 5 accommodated in the accommodating portion 7 is pressed toward the accommodating surface 7a side by the pressing convex portion 37 of the tip end portion 27a, so that the electric The terminal portion 6 of the component 5 and the contact pin 9 are brought into electrical contact with each other.

  At the same time, with the rotation of the lever portion 26, the pressing force of the side surface 35a of the transmission hole portion 35 of the lever portion 26 with respect to the protrusion 40 of the operation force transmitting means 4 is released, and the operation force transmitting means 4 becomes the third spring member. The urging force of 39 moves to the accommodation portion 7 side. That is, in FIG. 3, the left operating force transmitting means 4 moves rightward (+X direction), and the right operating force transmitting means 4 moves leftward (−X direction).

Again, focusing on the lower left pressing member 2 shown in FIG. 2, its operation will be described.
In FIG. 2, when the left operating force transmitting means 4 moves to the right (+X direction), as shown in FIG. 7, the pressing portion provided by inserting the tip portion into the elongated guide hole 42 of the operating force transmitting means 4 is provided. The pressing force of the operating force transmission means 4 on the transmission pin 22 of the member 2 is released. Therefore, the pressing member 2 advances in the direction of arrow A shown in FIG. 7 (inward along the substantially diagonal line of the housing portion 7) by the biasing force of the first spring member 13. At this time, the transmission pin 22 of the pressing member 2 guides the operating force transmitting means 4 along with the movement of the operating force transmitting means 4 in the +X direction and the movement of the pressing member 2 in the direction of arrow A shown in FIG. It moves in the hole 42 in the +Y direction. Similarly, the other three pressing members 2 also advance inward along the substantially diagonal line of the accommodating portion 7. As a result, the four pressing members 2 press the square portion of the electric component 5 accommodated in the accommodating portion 7 toward the center of the accommodating portion 7, and the electric component 5 is positioned at the substantially central portion of the accommodating portion 7.

  Specifically, the V-cut surface 25a of the guide roller 16 of the pressing member 2 abuts on the intersecting side surface 5a of the electric component 5 accommodated in the accommodating portion 7, and moves the electric component 5 toward the inner side of the accommodating portion 7. Position in the center. As a result, it is possible to center the electric component 5 by absorbing the outer size tolerance of the electric component 5.

  In the above description, the case where the four pressing members 2 are arranged corresponding to the four corners of the housing portion 7 has been described, but the present invention is not limited to this, and at least one of the rectangular housing portions 7 is provided. One set of pressing members 2 may be arranged so as to face each other in one diagonal direction, or one pressing member 2 may be arranged at any one corner of the housing portion 7. When the number of the pressing member 2 is one, it is preferable that the holding member 8 is provided with a positioning protrusion that is opposed to the pressing member 2 in the diagonal direction of the housing portion 7 and is brought into contact with the crossing side surface 5a of the electric component 5 to perform positioning.

  Further, the guide roller 16 may be provided only on a part of the pressing members 2, or may not be provided on all the pressing members 2. In this case, the pressing member 2 that does not have the guide roller 16 may be provided with a V-cut surface that abuts the intersecting side surface 5a of the electric component 5 at the contact portion with the electric component 5.
