However, in the measurement of an electro-optical component, it is necessary to perform an optical measurement as well as an electrical measurement. Therefore, in the measurement socket, the correct contact with the pad or connector provided on the electro-optical component and the correct alignment of the optical axis are both compatible. Is required. Particularly, when the electro-optical component is pressed to a reference position, the optical axis may be tilted or displaced depending on the method of pressing, and the importance of pressing the electro-optical component is increasing.

An object of the present invention is to provide a measuring socket capable of accurately positioning an electro-optical component to perform reliable conduction and alignment of an optical axis.

In order to solve the above problems, an aspect of the present invention is a measurement socket for measuring an electro-optical component, comprising: a base having a recess for accommodating the electro-optical component; A pressing member for pushing the electro-optical component onto the reference wall; A pressing means for biasing the pressing member in the direction of the reference wall; And a regulating member capable of imparting a regulating force to the biasing means to overcome the biasing force of the biasing means based on the operation of the cover covered on the base, wherein the regulating force is imparted to the biasing means by the regulating member when the cover is opened. Is moved in a direction away from the reference wall, and the regulating force is attenuated according to the operation of closing the cover, thereby moving the pressing member in a direction approaching the reference wall by the biasing force of the biasing means.

According to this configuration, the electro-optical component is pushed against the reference wall by a balance between the biasing force of the biasing means for biasing the pressing member in the direction of the reference wall and the regulation force applied to the biasing means from the regulating member based on the operation of the cover. You can set the applied pressure. Since the regulating force is attenuated as the cover is closed, the electro-optical component can be stably pressurized by the dominant sub-force when the cover is closed.

In the above measuring socket, it is preferable to provide a regulating force control means for setting a relationship between the relative distance between the cover and the base and the degree of the regulating force. In this way, by controlling the regulating force by the regulating force control means, the relationship between the relative distance between the cover and the base and the degree of the sub force can be arbitrarily set. Since the electro-optical component is a precision component, there is a fear that it will be damaged when excessively pressurized. By always exerting a regulating force on the auxiliary force, the degree of pressurization by the auxiliary force can be appropriately adjusted.

In the above measuring socket, the regulating force control means may have a link that drives the regulating member in conjunction with the operation of the cover. Thereby, it is possible to set the regulating force linked to the operation of the cover by the action of the link.

The measuring socket has an elastic member for imparting a regulating force to the biasing means through the regulating member when the cover is opened, and the greater the amount of elastic deformation of the elastic member is, the greater the regulating force is imparted to the biasing means from the regulating member. May be. Thereby, since the regulating force is provided when the elastic member is in a more free state, it is easy to increase the regulating force.

In the measuring socket, by covering the cover, the pressing member may be pressed by an acting portion provided on a surface opposite to the base of the cover. The acting portion includes a biasing means, a regulating member, and a transmission means for transmitting the biasing force of the biasing means to the pressing member as a driving force, and the pressing member presses the electro-optical component based on the driving force received from the transmission means. Thereby, the structure can be simplified by the acting part including the biasing means, the regulating member, and the transmission means.

In the measuring socket, the pressing member has an annular body, and an electro-optical component is inserted through the ring of the annular body, and the transmission means applies a driving force in a direction in which the inner circumference of the annular body approaches the electro-optical component. It may be supposed to be given to. Thereby, by pushing the inner circumference of the annular body against the electro-optical component, it is possible to stably pressurize in two directions at the same time.

In the measuring socket, the acting portion may further include a case, and the contact portion between the regulating member and the transmission means may be positioned inside the case. In addition, in the measuring socket, the contact portion between the biasing means and the transmission means may be positioned inside the case, or the biasing means may be positioned inside the case. In this way, when the pressing member is operated, the key portion is placed inside the case, thereby simplifying the configuration and ensuring operational stability.

In the measuring socket, the cover is rotatably supported with respect to the base, the pressing member and the link are provided on the base, and may be provided to move the link forward and backward in association with the rotational motion of the cover. Thereby, it is possible to set the regulating force linked to the rotation of the cover by the action of the link.

In the above measurement socket, the cover is rotatably supported with respect to the base, and the regulating force control means has an eccentric cam provided on the rotation shaft of the cover, and changes the regulating force by the operation of the eccentric cam in synchronization with the operation of the cover. It may be supposed to be. In this way, by using the eccentric cam as the regulating force control means, the device configuration can be downsized.

In the measuring socket, a center cover provided between the base and the cover and supported rotatably with respect to the base is additionally provided, and the regulating force control means has an eccentric cam provided on the rotation shaft of the center cover. The regulating force may be changed by the operation of the eccentric cam in synchronization with the operation. Accordingly, it is possible to pressurize the electro-optical component by operating the eccentric cam in conjunction with the operation of the center cover.

According to the present invention, there is provided a measuring socket capable of accurately positioning an electro-optical component to perform reliable conduction and alignment of an optical axis.

The measuring socket 1A according to the first embodiment is a socket used when electrical and optical measurements of the electro-optical component 100 are performed. The measurement socket 1A mounts the electro-optical component 100 to be measured, and performs electrical connection with the electro-optical component 100 and alignment of the optical axis.

In this embodiment, in the electro-optical component 100 to be measured, an optical lens unit 105 is provided on one side of the case 1011, and electrical conduction is performed on the other side of the case 1011. A pad 1012 is provided. Therefore, in the measurement socket 1A of this embodiment, by placing the electro-optical component 100 on the concave portion 11 of the base 10 to be described later and pressing it, the terminal 17 provided in the concave portion 11 and the Electrical conduction is obtained by contacting the pad 1012. Further, in the measurement socket 1A, by pressing the electro-optical component 100, the case 1011 is pushed against the reference wall W to position it, and the optical axis of the optical element such as the optical lens unit 105 is aligned. Carry out. That is, the measurement socket 1A achieves both electrical conduction to the electro-optical component 100 to be measured and optical alignment (optical axis alignment).

The measuring socket 1A according to the present embodiment includes a base 10, a pressing member 30, a biasing means 40, and a regulating member 50. In addition, in the following description, the direction orthogonal to the surface of the base 10 on which the electro-optical component 100 is mounted is the Z direction, one of the directions orthogonal to the Z direction is the X direction, the Z direction and the X The direction orthogonal to the direction is assumed to be the Y direction.

The base 10 has a concave portion 11 on which the electro-optical component 100 is mounted. For example, the base 10 has a base plate 150 and a guide plate 160 mounted on the base plate 150, and the concave portion 11 is provided at an approximately central portion of the guide plate 160. The concave portion 11 is composed of a through hole provided in the guide plate 160 and a bottom formed by the base plate 150. The concave portion 11 serves as a guide for determining an arrangement position of the electro-optical component 100.

A tapered portion extending upward is provided on the opening side of the concave portion 11, and a straight portion is provided below the tapered portion. The electro-optical component 100 placed on the concave portion 11 is drawn in by a taper and accommodated in the straight portion.

A terminal 17 is provided at the bottom of the recess 11 (above the base plate 150). When the electro-optical component 100 is accommodated in the recessed portion 11 and pressed in the Z direction, the pad 1012 provided on the back surface of the case 1011 and the terminal 17 are brought into contact with each other. Thereby, the measurement socket 1A can obtain electrical conduction with the electro-optical component 100.

The base 10 is covered with a cover 20. In the measuring socket 1A, the cover 20 is mounted rotatably with respect to the base 10. That is, the cover 20 is mounted through the hinge 27 provided at one end of the base 10. Accordingly, the cover 20 is provided to be opened and closed around the axis 28 of the hinge 27.

A latch 15 is provided on, for example, the base 10 of the measurement socket 1A. When the cover 20 is closed, the latch 15 is held against the click 25 of the cover 20 to maintain the closed state of the cover 20. The cover 20 is urged in an open direction by a spring 29 mounted on the shaft 28 of the hinge 27. Therefore, by removing the latch 15, the cover 20 is opened by the biasing force of the spring 29.

The pressing member 30 is a member for pressing the electro-optical component 100 accommodated in the concave portion 11 of the base 10 to the reference wall W. The reference wall W is, for example, an inner wall of the concave portion 11. As the reference wall W, a separate collision wall (standing piece) may be provided instead of the inner wall of the concave portion 11. In the measuring socket 1A, the pressing member 30 is disposed in a guide hole 10h provided adjacent to the concave portion 11 of the guide plate 160. The pressing member 30 is provided to be slidably within the guide hole 10h and contacts the case 1011 of the electro-optical component 10 to press the electro-optical component 100 in a predetermined direction.

The pressing member 30 may be one, or may be provided in plural. In the measuring socket 1A, two pressing members 30A and 30B are provided. Each of the pressing members 30A and 30B presses the case 1011 in two different directions to push the case 1011 against the reference wall W. That is, when viewed from above, the pressing member 30A presses one side of the rectangular case 1011 in the Y direction, and the pressing member 30B has the other side orthogonal to the side of the case 1011 in the X direction. Pressurize. When describing without distinguishing between the pressing members 30A and 30B, it will be referred to as the pressing member 30. The pressing member 30 is provided between, for example, a pair of guide rollers 35, and is designed to be smoothly slid in one direction along the XY plane by the guide rollers 35.

The biasing means 40 is biased in the direction of the pressing member 30 (reference wall W). For the biasing means 40, for example, a coil spring is used. The biasing means 40 is provided between the guide plate 160 and the rear end opposite to the front end of the pressing member 30 (the side in contact with the case 1011) and the pressing member 30 is electro-optical. An auxiliary force for pushing in the direction of the part 100 is applied to the pressing member 30.

For example, the pressing member 30A is applied with a biasing force F1a in the Y direction toward the electro-optical component 100 by the biasing means 40, and the pressing member 30B is applied by the biasing means 40. A negative force F1b is applied in the X direction toward the electro-optical component 100.

The regulating member 50 is a member that imparts a regulating force to the biasing means 40 to overcome the biasing force of the biasing means 40 based on the operation of the cover 20 covered on the base 10. In the measuring socket 1A, the regulating pin 51 connected to the pressing member 30 is the regulating member 50. In the measuring socket 1A, regulating members 50A and 50B are provided corresponding to each of the two pressing members 30A and 30B. When explaining without distinguishing between the regulating members 50A and 50B, it will be referred to as the regulating member 50.

The regulating pin 51, which is the regulating member 50, is inserted into the hole 30h provided on the back side of the pressing member 30. The regulation pin 51 is vertically installed at one end of the swing link 61 with respect to the shaft 61a. The swinging link 61 is mounted so as to be swingable about the axis 61a with respect to the base 10. A support pin 62 is erected and installed at the other end of the swing link 61 with respect to the shaft 61a. The support pin 62 is coupled with a hook pin 66 of a direct link 65 to be described later.

The direct link 65 drives the regulating pin 51, which is the regulating member 50, in conjunction with the operation of the cover 20. A passive part 68 that receives the operation of the cover 20 is provided at an end of the linear link 65 on the cover 20 side, and moves the linear link 65 by receiving the opening/closing operation of the cover 20. The oscillating link 61, the support pin 62, the direct moving link 65, and the hook pin 66 are constituent elements of the regulating force control means 60. The regulating force control means 60 sets the relationship between the relative distance between the base 10 and the cover 20 and the degree of the regulating force.

In the measurement socket 1A having such a configuration, when the cover 20 is opened, a regulating force is applied to the biasing means 40 by the regulating member 50, and the pressing member 30 is moved from the reference wall W. Move it away from you. On the other hand, when the cover 20 is closed, the regulating force is attenuated according to the relative distance between the cover 20 and the base 10, and the pressing member 30 is attached to the reference wall W by the biasing force of the biasing means 40. Move in the approaching direction. That is, the cover 20 is rotatably supported with respect to the base 10, and the pressing member 30 and the link (direct link 65 is provided on the base 10, and interlocks with the rotational motion of the cover 20). Thus, the link (direct link 65) is provided so as to move forward and backward.

Specifically, when the cover 20 is opened by the biasing force of the spring 29, the direct-acting link 65 moves toward the cover 20 by the opening operation of the cover 20. Then, by the movement of the linear link 65, the hook pin 66 pulls the support pin 62, and the swing link 61 swings. As the support pin 62 is pulled, the regulation pin 51 moves in a direction away from the electro-optical component 100 (recess 11) through the swinging link 61. By the movement of the regulation pin 51, the pressing member 30 is pulled against the biasing force of the biasing means 40, and moves in a direction away from the electro-optical component 100. That is, a regulating force is applied to the biasing means 40 from the regulating pin 51, and the pressing member 30 moves in a direction opposite to the direction in which the biasing force acts by the regulating force to overcome the biasing force.

For example, the regulating pin 51 of the regulating member 50A applies the regulating force F2a to overcome the biasing force F1a that biases the pressing member 30A in the direction of the reference wall W. ). The regulating force F2a originates from the force that opens the cover 20 by the spring 29, and is controlled by the relative distance between the cover 20 and the base 10 by the regulating force control means 60A. When the regulating force F2a becomes larger than the auxiliary force F1a, the pressing member 30A moves in the Y direction away from the reference wall W.

In addition, the regulating pin 51 of the regulating member 50B applies a regulating force F2b to the biasing means 40 to overcome the biasing force F1b that biases the pressing member 30B in the direction of the reference wall W. Grant. The regulating force F2b originates from the force opening the cover 20 by the spring 29, and is controlled by the relative distance between the cover 20 and the base 10 by the regulating force control means 60B. When the regulating force F2b becomes larger than the auxiliary force F1b, the pressing member 30B moves in the X direction away from the reference wall W.

On the other hand, when the cover 20 is closed, the linear link 65 moves in the X direction away from the hinge 27 by the closing operation of the cover 20. By the movement of the linear link 65, the force applied from the hook pin to the receiving pin 62 is weakened, and the regulating force opposed to the biasing force of the biasing means 40 is attenuated. As a result, the pressing member 30 moves in a direction approaching the reference wall W by the auxiliary force. The electro-optical component 100 is pressed by the movement of the pressing member 30, and the case 1011 is pressed against the reference wall W.

That is, in the operation of closing the cover 20, the regulating force F2a applied from the regulating pin 51 of the regulating member 50A to the biasing means 40 through the pressing member 30A is the biasing force F1a ) Is smaller than that. And, as the sub-force F1a overcomes the regulating force F2a, the pressing member 30A moves in the direction of the reference wall W and presses the electro-optical component 100. In accordance with the movement of the pressing member 30A, the swinging link 61 of the regulating force control means 60A swings, and the support pin 62 moves to follow the hook pin 66.

Further, the regulating force F2b applied from the regulating pin 51 of the regulating member 50B to the biasing means 40 through the pressing member 30B becomes smaller than the biasing force F1b. Then, as the auxiliary force F1b overcomes the regulating force F2b, the pressing member 30B moves in the direction of the reference wall W, thereby pressing the electro-optical component 100. As the pressing member 30B moves, the swinging link 61 of the regulating force control means 60B swings, and the support pin 62 moves to follow the hook pin 66.

In the control of the regulating force interlocked with the operation of the cover 20, the spring 29 urged in the direction of opening the cover 20 operates the regulating member 50 as an elastic member. The elastic deformation of the spring 29 is less when the cover 20 is open compared to when the cover 20 is closed. Accordingly, as the cover 20 is opened, as the elastic deformation of the spring 29 decreases, a greater regulating force is applied from the regulating member 50 to the biasing means 40. Thereby, when the spring 29 is in a more free state, a regulating force can be provided, and it becomes easy to increase the regulating force.

Further, the relationship between the relative distance between the cover 20 and the base 10 and the degree of the regulating force can be set by the link configuration of the regulating force control means 60. For example, the length from the axis of the oscillating link 61 to the regulation pin 51 or the support pin 62, or the locking start position of the support pin 62 and the hook pin 66 (length of the link, etc.) Is set by Accordingly, it is possible to set the timing of the action of the regulating force and the change of the regulating force according to the relative distance between the cover 20 and the base 10.

In addition, timing of pressing of the electro-optical component 100 in the Z direction (contact of the pad 1012 and the terminal 17) according to the closing operation of the cover 20 by the link configuration of the regulating force control means 60 And, it is possible to adjust the timing of pressing the case 1011 of the electro-optical component 100 by the pressing member 30 and pressing it against the reference wall W. For example, the cover 20 is closed to contact the electro-optical component 100, and before pressing the electro-optical component 100 in the Z direction, the pressing member 30 is pressed against the reference wall W. In the case of completing, the attenuation of the regulating force is started until the cover 20 contacts the electro-optical component 100 by the link configuration of the regulating force control means 60, and the pressurization by the pressing member 30 is completed. You just need to set up the link configuration to do so.

According to such a measuring socket 1A, the regulating member 50 based on the biasing force of the biasing means 40 for biasing the pressing member 30 in the direction of the reference wall W and the operation of the cover 20 The pressing force for pushing the electro-optical component 100 against the reference wall W can be set by a balance with the regulating force applied to the biasing means 40 from ). Further, since the regulating force is attenuated as the cover 20 is closed, the electro-optical component 100 can be stably pressed by the prevailing sub-force in the state where the cover 20 is closed.

In addition, by controlling the regulating force by the regulating force control means 60, the relationship between the relative distance between the cover 20 and the base 10 and the degree of the sub force, and the reference wall W of the electro-optical component 100 The pressurization timing can be set arbitrarily. Since the electro-optical component 100 is a precision component, there is a fear that it will be damaged if excessively pressed. By always acting the regulating force on the sub-force, the degree of pressurization by the sub-force can be appropriately adjusted, and it is possible to achieve stable pressurization and regulation of excessive pressing force on the electro-optical component 100.

7 is an enlarged perspective view of the pressing member.

8A to 8C are schematic cross-sectional views illustrating the operation of the socket for measurement according to the second embodiment.

In the measuring socket 1B according to this embodiment, the cover 20 is mounted rotatably with respect to the base 10. The regulating force control means 60 has an eccentric cam 70 provided on the rotation shaft 28 of the cover 20 and a sliding portion 71 provided to be movable by the eccentric cam 70. The sliding part 71 is provided between the base plate 150 and the guide plate 160.

The sliding part 71 is pressed in a direction away from the reference wall W by a coil spring (elastic member) 75 provided between the base plate 150 and the base plate 150. A regulation pin 51 is erected in the slide portion 71 and is inserted into the hole portion 30h of the pressing member 30 disposed on the sliding portion 71. On the side of the eccentric cam 70 in the sliding portion 71, a roller 72 capable of contacting the eccentric cam 70 is provided.

The pressing member 30 is disposed in the guide hole 10h provided in the guide plate 160 and is provided so as to advance and retreat along the inner wall of the guide hole 10h. In this embodiment, the guide hole 10h and the pressing member 30 are disposed between the concave portion 11 and the eccentric cam 70. The pressing member 30 is capable of advancing and retreating in the X direction along the guide hole 10h.

The pressing means 40 is provided between the rear end of the pressing member 30 and the inner wall of the guide hole 10h facing the rear end of the pressing member 30, and the pressing member 30 is attached to the reference wall (W). ) In the direction of.

In order to measure the electro-optical component 100 by the measurement socket 1B, first, as shown in Fig. 8 (a), with the cover 20 open, the recess 11 of the base 10 is The electronic optical component 100 is placed. The case 1011 of the electro-optical component 100 is drawn into the tapered portion of the concave portion 11 and accommodated in the straight portion. When the cover 20 is open, the roller 72 of the sliding portion 71 is not in contact with the eccentric cam 70. In this state, the sliding portion 71 is biased in a direction away from the reference wall W by the biasing force of the coil spring 75, which is an elastic member, and the pressing member 30 is also referenced through the regulation pin 51. It is pulled in the direction away from the wall W (the hinge 27 side). That is, the biasing force of the coil spring 75 becomes a regulating force and is applied to the pressing member 30, and overcomes the biasing force of the biasing means 40 to move the pressing member 30 toward the hinge 27 side. Thereby, the pressing member 30 is separated from the case 1011 of the electro-optical component 100.

Next, as shown in Fig. 8(b), the cover 20 is closed. When the cover 20 is closed, the eccentric cam 70 contacts the roller 72 and presses the sliding part 71. When the sliding part 71 is pressed, the regulation pin 51 moves in the direction of the reference wall W. Thereby, the regulating force imparted to the biasing means 40 from the regulating pin 51 through the pressing member 30 is attenuated, and the pressing member 30 is moved by the biasing force of the biasing means 40. Will move in the direction of. Thereby, the pressing member 30 presses the case 1011 of the electronic component 101 and pushes the case 1011 against the reference wall W. As a result, the position of the electro-optical component 100 is determined.

In addition, when the cover 20 is closed as shown in FIG. 8 (c), the locking pin 51 and the pressing member 30 are not caught, and the regulating force is eliminated, so that only the biasing force by the biasing means 40 is eliminated. Positioning of the electro-optical component 100 is completed by the pressing member 30. Then, the electro-optical component 100 is pressed in the Z direction by the cover 20. As a result, the pad (not shown) provided on the back surface of the electro-optical component 100 and the contact pin 91 come into contact, and electrical connection is made.

By using the eccentric cam 70 provided in the measurement socket 1B, the operation of closing the cover 20 by changing the profile of the eccentric cam 70 and the electro-optical component 100 by the pressing member 30 The pressing timing and the change in the pressing force can be set arbitrarily.
