Description

  The present invention relates to an electrical component socket applied to an inspection of an electrical component such as a burn-in test. Thus, the present invention relates to an electrical component socket that enables the electrical component to be positioned with high precision by providing a biasing means that presses in a diagonal direction and shifts it diagonally.

  In general, a socket for an electrical component applied to an inspection such as a burn-in test of an electrical component generally has a clearance between the accommodating portion and the electric component in order to improve the accommodating property of the electric component with respect to the accommodating portion provided in the socket main body portion. Provided. Therefore, in order to position the electrical component at a predetermined position of the housing portion, it is necessary to press the housed electrical component in the diagonal direction and position the electrical component with respect to the positioning portion formed in the housing portion.

  In this type of conventional socket for electric parts, for example, a socket main body having an accommodating portion for accommodating the electric component and a terminal provided on the lower surface of the electric component can be brought into contact with the socket main body. In addition, a plurality of contact pins and a presser cover pivotally attached to the socket body portion are provided, and the corner portions of the electrical components are guided around the socket body housing portion when the electrical components are housed in the housing portion. When the guide cover is closed and the presser cover is closed, the electrical component housed in the housing part is pressed and held so that the terminal of the electrical component contacts the contact pin, and the presser cover is closed. Along with this, there is one provided with a biasing means that presses a corner portion of an electrical component in a diagonal direction and abuts the corner portion on the opposite side of the corner portion with a guide protrusion (for example, a patent) Sentence Reference 1).

  As shown in FIG. 11, this biasing means is configured such that a cantilever leaf spring 3 is disposed substantially horizontally on a receiving portion 2 provided in the socket main body 1 to fix the base end portion 3 a to the socket main body 1. As shown in FIG. 12, a pressing block 4 that engages with the tip 3b side of the leaf spring 3 is arranged on the socket body 1 so as to be movable up and down and is moved upward by an elastic member (not shown). It has a biased configuration. Then, when the presser cover (not shown) is open, the pressing block 4 is raised, and the tip 3b of the leaf spring 3 is brought into contact with the side surface 4a of the pressing block 4 as shown in FIG. As shown in FIG. 12, the pressing block 4 is lowered with the closing operation of the presser cover, and the tip 3b of the leaf spring 3 is retracted from the side surface 4a of the pressing block 4 shown in FIG. The plate spring 3 is moved to the side surface 4b and returned to the position indicated by the solid line in FIG. Accordingly, the corner portion of the electric component is pressed by the leaf spring 3 in the diagonal direction indicated by the arrow P, and the corner portion on the opposite side of the corner portion is brought into contact with the guide protrusion 5. I am doing so.

  However, in such a conventional socket for electrical parts, the leaf spring 3 rotates diagonally around the end O of the base end part 3a so that the corners of the electrical part are diagonally moved by elastic force. As shown in FIG. 13, a force in the tangential direction of a circle centering on the point O acts on the electrical component 6 as shown in FIG. The direction of the force acting on the corner portion 6 changes, for example, in the directions of arrows Q, R, and S in the figure, and a force that coincides with the diagonal direction of the arrow P shown in FIG. Therefore, a force in the rotational direction acts on the electrical component 6 during the shifting operation, and the positioning accuracy of the electrical component 6 may be deteriorated. The direction of the force acting on the electrical component 6 varies depending on the posture when the electrical component 6 is accommodated in the accommodating portion 2 and is not constant.

Further, since the pressing block 4 is lowered in accordance with the closing operation of the presser cover, the leaf spring 3 is restored by the elastic force so as to press the corner portion of the electrical component in the diagonal direction. When 4 is lowered, the leaf spring 3 may be twisted due to friction with the pressing block 4, and the pressing direction of the electrical component may deviate from the diagonal direction of the arrow P shown in FIG. Therefore, also in this case, there is a possibility that the positioning accuracy of the electrical component is deteriorated.

  Further, as shown in FIG. 1, a plurality of contact pins 7 are implanted in the socket body 1 at a portion corresponding to the housing 2 of the socket body 1. The contact pin 7 is for electrically connecting a terminal of the electrical component and a wiring portion of a circuit board (not shown) disposed at the lower portion of the socket body 1, and is an insertion hole provided in the housing portion 2. 12 is inserted in the shape of a matrix in a state where the tip end portion protrudes toward the accommodating portion 2 and the opposite end portion protrudes from the lower surface of the socket body portion 1 (see FIG. 2 or FIG. 3). And the front-end | tip part by the side of the accommodating part 2 can be moved up and down elastically, the dispersion | variation in the terminal height position of an electrical component is absorbed, and the stable contact with a terminal is enabled.

  A socket cover 8 is provided on one side of the socket body 1 as shown in FIG. The socket cover 8 presses an electrical component positioned and accommodated on the upper surface of the accommodating portion 2 from above to bring the terminal of the electrical component and the contact pin 7 into electrical contact with each other. It is provided in the middle right side part so that opening and closing is possible by the pivot pin 20. As shown in FIG. 1, a chord spring 21 is wound around the pivot pin 20, and both ends thereof are brought into contact with the right side of the socket body 1 and the lower surface of the socket cover 8. The socket cover 8 is constantly urged in the opening direction by the elastic force. As shown in FIG. 2, the socket cover 8 includes a component pressing portion 22, a boss 23 as an operation portion, and a locking lever 24.

  A component pressing portion 22 is provided in the center portion of the socket cover 8 on the side of the socket main body 1.

The contact portion with the protruding portion 17a is formed in a slope shape so that the vertical movement of the boss 23 can be converted into the horizontal movement of the operation member 17.

  Further, as shown in FIG. 2, a locking lever 24 is provided on the side of the socket cover 8 opposite to the pivot pin 20 so as to be rotatable by another pivot pin 26. The other pivot spring 27 is wound around the pivot pin 26, and both ends thereof are brought into contact with the upper surface of the socket body 1 and the inner surface of the upper side of the locking lever 24, so that the elasticity is increased. The latch lever 24 is always urged in the standing direction by force, and is latched to the left side surface portion of the socket body 1 so that the socket cover 8 can be kept closed.

Next, the operation of the thus configured electrical component socket of the first embodiment will be described.
The electrical component socket is installed on a circuit board (not shown), and the contact pins 7 are electrically connected to corresponding wiring portions of the circuit board by, for example, soldering. In such a state, first, the socket for electrical parts stands up and opens the socket cover 8 as shown by a broken line in FIG. At this time, since the pressing of the operation member 17 of the biasing means 9 is released, the biasing means 9 extends the return spring 16 and contracts the biasing spring 15 as shown in FIG. The pressing member 14 is retracted to a predetermined position in the direction of the arrow D, and the housing portion 2 is opened so that the electrical component can be housed.

  Next, for example, an electrical component conveyed by an automatic machine is dropped into the housing portion 2 from above the socket main body portion 1. As a result, the electrical component is guided by the guide portion 10 formed so as to surround the storage portion 2 as shown in FIG.

  Next, the socket cover 8 is closed by, for example, an automatic machine, and the locking lever 24 provided in the socket cover 8 is locked to the side surface portion of the socket body 2 to be closed. At this time, with the closing operation of the socket cover 8, the boss 23 provided so as to project from the socket cover 8 presses the projecting portion 17 a of the operation member 17 of the side shift means 9 downward from above.

  Since the contact portion of the boss 23 with the protrusion 17a of the operating member 17 is formed in a slope shape as shown in FIG. 2, the boss 23 is pressed horizontally by the downward pressing of the boss 23. Directional force acts. Therefore, the protrusion 17a of the operating member 17 is pushed into the notch 19 provided on the rear side surface 14d of the pressing member 14 by the boss 23 as shown in FIG. 4B, and the operating member 17 contracts the return spring 16. Let As a result, the return force for urging the pressing member 14 of the return spring 16 shown in FIG. 4A in the direction of arrow D is released, and the pressing member 14 is moved to the biasing spring 15 as shown in FIG. Are moved in the same direction by the elastic force in the direction of arrow E.

  Then, the pressing member 14 has the two pressing portions 14a and 14b provided at the left and right symmetrical positions with respect to the diagonal line of the housing portion 2, and each contact position on the side surface intersecting the one corner portion of the electrical component 6 is accommodated in the housing portion. 2 is pressed in the diagonal direction, and the opposite side surface is brought into contact with the positioning portion 11 provided at the corner portion of the housing portion 2 to position the electrical component 6 (see FIG. 4B). Thereby, the terminal of the electrical component 6 and the contact pin 7 can contact. In the closed state of the socket cover 8, the electrical component 6 is pressed from above by the component pressing portion 22, and the terminal of the electrical component 6 and the contact pin 7 come into contact with each other.

  Since the component pressing portion 22 is elastically held by the socket cover 8 by the elastic member 25, the component pressing portion 22 is provided so as to protrude toward the socket body portion 1 side of the socket cover 8 when the socket cover 8 is closed. The contact portion 22a of the component pressing portion 22 always contacts the upper surface of the electrical component 6 and presses the electrical component 6 evenly downward. Therefore, when the socket cover 8 is closed, there is no possibility that the contact portion 22a of the component pressing portion 22 will come into contact with the electrical component 6 and move the electrical component 6, thereby deteriorating the positioning accuracy of the electrical component 6. There is no.

  As described above, the electrical component socket according to the first embodiment of the present invention is a pair of pressing members provided so as to protrude in the pressing direction of the pressing member 14 of the pressing unit 9 that presses and biases the electrical component 6. Since the parts 14a and 14b are in contact with the side surfaces intersecting one corner of the electrical component 6 so as to press the electrical component 6 in the diagonal direction of the housing portion 2, the electrical component 6 has a diagonal force. Can act. Thereby, the positioning accuracy of the electrical component 6 can be improved.

  Further, the biasing means 9 biases the pressing member 14 that presses the electrical component 6 in the biasing direction in the opposite directions by the biasing spring 15 and the return spring 16. At the time of positioning, an operating force is applied to the return spring 16 so as to contract the extension spring 15 so that the pressing member 14 is moved in the offset direction by the elastic force of the offset spring 15. Can do. Thereby, it is possible to eliminate the direct action of the operating force with respect to the shifting operation of the pressing member 14, and to apply only the elastic force of the shifting spring 15 to the pressing member 14. Therefore, since only the force in the diagonal direction of the accommodating portion 2 acts on the electrical component 6, the positioning accuracy of the electrical component 6 can be improved.

  Furthermore, since the elastic load of the return spring 16 is larger than the elastic load of the one-sided spring, the elastic force of the return spring 16 can be applied to the pressing member 14 at all times. Thereby, in the steady state, the pressing member 14 can be retracted to a predetermined position to hold the accommodating portion 2 in the open state.

  And since the one-sided means 9 is arranged in a space part sandwiched between the guide part 10 and the accommodating part 2 at one corner of the accommodating part 2, the guide part 10 is formed so as to surround the accommodating part 2. The electrical component can be correctly guided and accommodated in the accommodating portion 2 when the accommodating portion 2 is open.

  FIG. 5 shows another configuration example of the justifying means 9. 5 is configured such that a pair of pressing portions 14a and 14b formed so as to protrude in the direction of shifting and a portion sandwiched between the pair of pressing portions 14a and 14b are moved backward in the direction opposite to the shifting direction.

One of the return springs 16 arranged to urge the pressing member 14 in the return direction, and the protrusion 17a through the notch 19 provided in the escape portion 28, is urged by the return spring 16 and the locking portion 17b is notched to the notch 19. The operation member 17 latched to the edge of the is provided. As a result, when the operating member 17 is operated and the return spring 16 is contracted, the return force of the return spring 16 is released, and the pressing member 14 is moved by the elastic force of the biased spring 15 to press the electrical component 6. can do.

  Further, FIG. 6 shows still another configuration example of the justifying means 9. 6 is replaced with a pair of one-sided springs 15 arranged at portions corresponding to the pressing portions 14a and 14b in the one-sided means 9 shown in FIG. One is arranged on a diagonal line, and the biasing spring 15 and the return spring 16 urge the pressing member 14 in the opposite direction on the same straight line. Also in this case, by operating the operating means 18 and contracting the return spring 16, the pressing member 14 can be caused to perform a shifting operation by the shifting spring 15 to press the electrical component 6. In this case, a pair of return springs 16 may be arranged at symmetrical positions with respect to the diagonal line.
