Description

  The present invention relates to a test socket, and more particularly, to a test socket that is used for connecting an assembled electronic component to an inspection machine.

  For semiconductors, LCD modules, image sensors, camera modules, etc., after the assembly of each part is completed, supply the same operation signal and power as the electronic parts to be mounted and undergo quality inspections to check whether they operate normally. .

  The test socket is a device that connects the LCD module, the camera module, and the like to the inspection machine so that the signal of the inspection machine can be transmitted to the LCD module, the camera module, and the like.

  In this connection, Korean Patent Registration No. 1006243 discloses an electronic module inspection socket. Korean Registered Patent Publication No. 1006243 discloses a body part that forms a mounting part on which an electronic module as an inspection object is mounted, and a hinge part that is hinged to one side of the body part so as to be rotated. A lid that covers the upper part of the body part so as to prevent the electronic module from being detached while contacting and selectively pushing the electronic module, and provided on one or both sides of the body part and the lid part when the lid part is closed An operating part to be operated semi-automatically, a clip part to maintain the closed state of the lid part by the operating part, and a pin assembly provided in the body part and connected to the electronic module when the lid part is closed; A printed circuit board connected to the pin assembly and electrically connected to the inspection apparatus.

  Korean Registered Patent Publication No. 1006243 discloses a test socket in which when a worker rotates a lid, a member (connection pin block or push block) provided on the lid pushes an electronic module placed on the mounting portion. The operation structure for connecting the connection pins (hereinafter referred to as “connection pins”) to the connector (hereinafter referred to as “connector”) of the electronic module is formed.

  However, Korean Registered Patent Publication No. 10063443 has the following disadvantages.

  (1) Since the connection pin and the connector are connected in a state where the lid covers the electronic module, the electronic module and the inspection device are electrically connected in a state where the field of view of the operator with respect to the electronic module is blocked. Form. Therefore, the operator cannot visually confirm whether or not the connection pin and the connector are normally connected.

  The operator can consider that the connection pin and the connector are normally connected when the electronic module is determined to be good as a result of the inspection of the electronic module. It is difficult to accurately determine whether the determination is due to an abnormal connection or due to a defect in the electronic module, and there is a difficulty that additional confirmation must be made.

  (2) An operating structure is formed in which the connecting pin is connected to the connector while the lid is rotated by the operator's hand, and the lid forms a rotation radius of approximately 90 degrees around one side of the body. Therefore, the installation space for the test socket occupies a space obtained by adding the operator's operation space to the plane area of the trunk portion and the height of the lid portion.

  In an inspection room where an inspection process of an electronic module is performed, various machine materials are provided in a limited space. Various machine materials are placed within a short distance of the worker for convenience and efficiency of inspection work. Therefore, the greater the space occupied by the test socket in the inspection room, the less convenient and efficient the inspection work is.

  (3) Since the lid portion rotates to connect the connection pin to the connector, the lid portion forms an external force that connects the connection pin and the connector while performing a curved motion in which the direction of the force changes every moment. Therefore, the rotational force of the lid is transmitted to the connection pin and the connector in a direction inclined with respect to the connection direction of the connection pin and the connector (before the connection pin and the connector are completely connected), and is transmitted to the contact portion between the connection pin and the connector. Causes frictional forces due to external forces that do not match the ideal connection direction.

  As a result, the connection pin and the connector are damaged by the frictional force. In particular, the connection pins connected to a large number of connectors accumulate damage due to frictional forces, so that the life is shortened quickly.

  In this regard, Korean Patent Registration No. 759081 discloses a socket for camera module inspection. Korean Registered Patent Publication No. 759081 is a body part to which a camera module as an inspection object is mounted; an operation part coupled to the body part so as to be movable up and down; an elevating guide for guiding the vertical movement of the operation part; A clip portion that is fixed so as to maintain a lowered state; a pin assembly that is located on one side of the operating portion and is connected to a connector pin of the camera module; a printed circuit board connected to the pin assembly; A connecting wire for connecting the inspection device; and a lens crimping portion provided in the operating portion.

  (4) Since the Korean Registered Patent Publication No. 759081 forms an operating structure in which the operating part is raised and lowered in the vertical direction, the above problems (1) to (3) can be partially solved. Since the lens crimping part is located on the upper side of the mounting plate, an accident occurs in which the camera module moved to the mounting plate collides with the lens crimping part and the lens crimping part interferes with the operator's line of sight with respect to the mounting plate. Has structural limitations.

After moving along, it moves along the movement path in the opposite direction to W1 and is positioned below the top cover 200 again. (See Figs. 1 and 4)

  Korean Registered Patent Publication No. 1006243 discloses a test socket in which when a worker rotates a lid, a member (connection pin block or push block) provided on the lid pushes an electronic module placed on the mounting portion. The operation structure for connecting the connection pins (hereinafter referred to as “connection pins”) to the connector (hereinafter referred to as “connector”) of the electronic module is formed.

  However, Korean Registered Patent Publication No. 10063443 has the following disadvantages.

  (1) Since the connection pin and the connector are connected in a state where the lid covers the electronic module, the electronic module and the inspection device are electrically connected in a state where the field of view of the operator with respect to the electronic module is blocked.

  The operator can consider that the connection pin and the connector are normally connected when the electronic module is determined to be good as a result of the inspection of the electronic module. It is difficult to accurately determine whether the determination is due to an abnormal connection or due to a defect in the electronic module, and there is a difficulty that additional confirmation must be made.

  (2) An operating structure is formed in which the connecting pin is connected to the connector while the lid is rotated by the operator's hand, and the lid forms a rotation radius of approximately 90 degrees around one side of the body. Therefore, the installation space for the test socket occupies a space obtained by adding the operator's operation space to the plane area of the trunk portion and the height of the lid portion.

  In an inspection room where an inspection process of an electronic module is performed, various machine materials are provided in a limited space. Various machine materials are placed within a short distance of the worker for convenience and efficiency of inspection work. Therefore, the greater the space occupied by the test socket in the inspection room, the less convenient and efficient the inspection work is.

  In this regard, Korean Patent Registration No. 759081 discloses a socket for camera module inspection. Korean Registered Patent Publication No. 759081 is a body part to which a camera module as an inspection object is mounted; an operation part coupled to the body part so as to be movable up and down; an elevating guide for guiding the vertical movement of the operation part; A clip portion that is fixed so as to maintain a lowered state; a pin assembly that is located on one side of the operating portion and is connected to a connector pin of the camera module; a printed circuit board connected to the pin assembly; A connecting wire for connecting the inspection device; and a lens crimping portion provided in the operating portion.

  (4) Since the Korean Registered Patent Publication No. 759081 forms an operating structure in which the operating part is raised and lowered in the vertical direction, the above problems (1) to (3) can be partially solved. Since the lens crimping part is located on the upper side of the mounting plate, an accident occurs in which the camera module moved to the mounting plate collides with the lens crimping part and the lens crimping part interferes with the operator's line of sight with respect to the mounting plate.

The height of the vertical surface 122 and the inclined surface 121 is more than several tens of times the connection depth between the connector C and the connection pin P. Since it does not need to be formed, the height occupied by the test socket 10 in the examination room can be reduced, so that the problem (2) of the prior art can be solved.

  The push block 320 is separated from the electronic component L in the moving path W1, and pressurizes the electronic component L downward (in the connecting direction of the connector C and the connecting pin P) in the moving path W2. The problem (3) can be solved.

  The rolling member 330 is configured to roll on the inclined surface 121 and the vertical surface 122, is formed in a cylindrical shape, and is rotatably coupled to the slider 310 by a bolt or a pin.

  As shown in FIGS. 7 and 8, the top cover 200 and the pressure module 300 are connected by the first elastic member E1. The first elastic member E <b> 1 is a compression spring that is configured to form a recovery force that causes the rolling member 330 to be in close contact with the inclined surface 121 and the vertical surface 122. Link. The slider 310 and the top cover 200 are formed with holes corresponding to both ends of the first elastic member E1.

  As shown in FIGS. 4 and 5, the first elastic member E1 moves the rolling member 330 to the inclined surface 121 or the vertical surface 122 (by pulling the slider 310 away from the electronic component L by the recovery force). Adhere closely. When the top cover 200 is raised and lowered, the rolling member 330 rolls while being in close contact with the inclined surface 121 or the vertical surface 122.

  6 and 7, that is, in a state where the top cover 200 is raised to the maximum by the actuator A, the rolling member 330 is brought into close contact with the upper end portion of the inclined surface 121 by the recovery force of the first elastic member E1. At this time, the push block 320 is located on the lower side of the top cover 200, and the operator can easily attach the electronic component L to the attachment unit 110.

  As shown in FIG. 8, when the top cover 200 is lowered by the actuator A, the pressurizing module 300 is pushed by the inclined surface 121 in the process of lowering the top cover 200 and slides upward on the electronic component L. Will descend in the direction.

  The push block 320 is separated from the electronic component L when the rolling member 330 rolls on the inclined surface 121. When the rolling member 330 rolls on the vertical surface 122, the electronic component L is placed on the lower side (connector C and connection pin P). Pressure direction). In the state shown in FIG. 8, the connector C and the connection pin P maintain a stable connection state by the pressing force of the push block 320.

  After the test by the inspection machine is completed, the top cover 200 is automatically raised by the actuator A. The pressurizing module 300 slides in a direction away from the electronic component L by the recovery force of the first elastic member E1 when the top cover 200 is raised.

  When the top cover 200 is raised or lowered by the actuator A, the speed of the top cover 200 can be controlled to be constant, so that the connector C and the connection pin P can be connected more stably. Since there is no need to press, there is an advantage that the height occupied by the test socket 20 in the examination room can be minimized.

  According to the present invention, the pressing module is pushed by the inclined surface in the process of lowering the top cover and slides to the upper side of the electronic component, so that the visual field of the operator for the electronic module is ensured during the inspection, and the socket It is possible to provide a test socket in which the height of the installation space is reduced and the connection pins and the connectors are connected in an ideal connection direction.

  Further, when the actuator raises the top cover, the pressure module slides away from the electronic component by the recovery force of the first elastic member, so that the connection between the connection pin and the connector is not a manual operation by the operator. It is possible to provide a test socket configured to be implemented by an automatic connection structure using force.

  Although specific embodiments of the present invention have been described and illustrated above, the present invention is not limited to the described embodiments, and various modifications and variations can be made without departing from the spirit and scope of the present invention. What is possible is obvious to those with ordinary knowledge in the art. Therefore, such modifications or variations should not be individually understood from the technical idea and viewpoint of the present invention, and the modified embodiments should belong to the scope of the claims of the present invention.
