  The socket for electrical parts is automatically mounted on the circuit board by sucking the bottom surface of the housing by the suction nozzle. Automatic mounting by a mounting machine is performed by supplying a supply tape in the form of a roll on which electrical component sockets are juxtaposed to the mounting machine along the rails, and by sequentially sucking the electrical component sockets by the mounting machine suction nozzle. This is done by removing it from the circuit board and placing it on the circuit board.

  When the electrical component socket is automatically mounted, the bottom surface of the housing becomes a suction surface that is sucked by the suction nozzle. However, if the contact terminal is arranged at the bottom of the housing, the area of the suction surface for automatic mounting becomes small, and the suction nozzle may not be able to suck. Further, if the length of the contact terminal is shortened in order to increase the suction surface, the elastic force of the elastic portion is reduced and it becomes impossible to ensure the contact pressure with the electrical component.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an electrical component socket capable of ensuring contact pressure between a contact terminal and an electrical component and having a housing capable of automatic mounting. .

In order to solve the above-described problems, an electrical component socket according to the present invention has a box-shaped housing that is opened upward to which an electrical component having a plurality of contact portions is mounted on a bottom surface, and the contact portion of the electrical component abuts.

The auxiliary suction surface protrudes to the vicinity of the position of the connection portion of the contact terminal moved downward by the mounting of the electrical component.

  In the electrical component socket according to the present invention, the contact terminal has a fixing portion fixed to the side wall of the housing, and the fixing portion can be attached to the side wall of the housing from below. It is structured as a feature.

  According to the socket for electrical parts according to the present invention, the suction surface has a bowl-shaped auxiliary suction surface protruding toward the opening of the housing portion, thereby increasing the area of the suction surface by the auxiliary suction surface. In addition, since the contact terminal can be disposed below the auxiliary suction surface, the elastic part of the contact terminal can be lengthened, so that the contact pressure between the contact terminal and the contact part of the electrical component can be ensured.

  Further, according to the electrical component socket according to the present invention, the contact terminal connection portion is disposed above the opening portion and moves to the height of the opening portion when the electrical component is mounted on the housing, and the auxiliary suction surface is By projecting to near the position of the contact terminal connecting part moved downward due to the mounting of the electrical component, the mounting suction surface is enlarged without interfering with the downward movement associated with the insertion of the electrical part of the contact terminal connecting part. be able to.

  Furthermore, according to the socket for electric parts according to the present invention, the contact terminal has a fixing portion fixed to the side wall of the housing, and the fixing portion is attachable to the side wall of the housing from below. Even if the auxiliary suction surface is formed, the contact terminal can be easily attached to the housing.

  Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of an electrical component socket and electrical component 50 in the present embodiment, FIG. 2 is a plan view of the housing 1 in the present embodiment, and FIG. 3 is a cross-sectional view taken along line AA in FIG. As shown in each of these drawings, the electrical component socket in the present embodiment is provided in the housing 1 to which the electrical component 50 is mounted, and a plurality of housings 1, and includes the electrical component 50 and a circuit board (not shown). And a contact terminal 10 that can be electrically connected to each other. In addition, the cover member 40 is attached to the electrical component 50 from above while being attached to the housing 1.

  The electrical component 50 mounted on the housing 1 is made by processing a semiconductor such as silicon of several millimeters square so that a large number of circuit elements function as an electronic circuit. In the present embodiment, the electrical component 50 is a camera module in which an optical component is further incorporated. However, the electrical component 50 is not limited to the camera module.

  The electrical component 50 has a plurality of contact portions on the bottom surface. The electrical component 50 is mounted on the housing 1 and brought into contact with a contact portion (not shown) and the thin plate-like contact terminal 10, so that the circuit of the electrical component 50 is provided. Electrical connection to the substrate is possible. One of the side surfaces 51 of the electrical component 50 is formed with a protruding portion 56 that protrudes outward from the side surface 51 and is disposed on a guide portion 30 of the housing 1 described later. Further, an engaged portion 57 that engages with a claw portion 46 of a cover member 40 described later is formed on the side surface 51 of the electrical component 50.

  The housing 1 that houses the electrical component 50 is formed of an insulating material such as a resin and is formed in a box shape that is open at the top. The housing 1 is in a state in which the electrical component 50 is mounted by inserting and fitting the electrical component 50 from above. As shown in FIGS. 1 and 2, a guide portion 30 is provided on one side of the side wall 2 of the housing 1 to place a protruding portion 56 formed on the side surface 51 of the electrical component 50. In addition, the other three surfaces other than the side wall 2 on which the guide portion 30 is formed have restricting portions 31 that interfere with the protruding portions 56 of the electrical components 50, and the upper end portion of the restricting portion 31 is the upper end of the side wall 2. It is formed continuously with the part.

  As described above, the electric component 50 is mounted on the housing 1 only when the side surface 51 having the protruding portion 56 and the side wall 2 provided with the guide portion 30 are inserted in correspondence with each other, and in other directions, the restricting portion of the housing 1 is mounted. 31 and the protrusion 56 interfere with each other so that the housing 1 cannot be mounted. Therefore, it is possible to prevent the electric component 50 from being inserted into the housing 1 in the wrong direction.

  Further, the housing 1 has a grounding member 60 on each side wall 2 as shown in FIG. The ground member 60 conducts a metal cover member 40 described later to the circuit board, and protects the electrical component 50 together with the cover member 40 from static electricity or electrical noise. As shown in FIGS. 1 and 3, the ground member 60 includes a fixing portion 61 that is fixed to the side wall 2 of the housing 1 and a connection portion 62 that is bonded to the circuit board. The fixed portion 61 has a concave portion 63 that engages with the elastic piece 41 of the cover member 40 on the outer surface. The connecting portion 62 of the ground member 60 is formed in a U-shaped cross section, and the lower end portion is joined to the circuit board by soldering or the like.

As shown in FIG. 1, the cover member 40 covers the electrical component 50 from above and is detachable from the outer surface of the housing 1. The cover member 40 protects the electrical component 50 by being attached to the housing 1. An opening 45 is formed on the upper surface of the cover member 40 so that the optical component incorporated in the upper part of the electrical component 50 is exposed. A plurality of claw portions 46 that engage with engaged portions 57 formed on the side surface 51 of the electrical component 50 are formed at the edge of the opening 45. When the cover member 40 is attached to the housing 1, the electric component 50 is pressed from above by the claw portion 46, and the electric component 50 is prevented from coming out of the housing 1.

  Further, the side surface of the cover member 40 has an elastic piece 41 at a position corresponding to the grounding member 60 of the housing 1. The elastic piece 41 is provided with elasticity by bending a part of the side surface of the cover member 40 inward. Since the fixing portion 61 of the grounding member 60 has a concave portion 63 on the outer surface, when the cover member 40 is mounted on the housing 1, the elastic piece 41 engages with the concave portion 63 of the fixing portion 61 to cover the cover member 40 and the grounding member 60. , And the electrical component 50 is protected from static electricity or electrical noise, and the cover member 40 is less likely to be detached from the housing 1.

  A plurality of contact terminals 10 provided in the housing 1 are formed of a conductive material such as metal, and a connection portion 11 formed at the tip thereof is disposed in the housing 1 corresponding to a contact portion of the electrical component 50. The connection part 11 has an upper part formed in a substantially semicircular cross section in order to ensure contact with the contact part of the electrical component 50. The contact terminal 10 includes a fixed portion 12 fixed in the side wall 2 of the housing 1 and an elastic portion 18 connected to the lower end portion of the fixed portion 12, and the connection portion 11 is formed at the tip of the elastic portion 18.

The insertion part 5 is formed from the lower end of the side wall 2 to a predetermined position in the side wall 2, and the contact terminal 10 is fixed by press-fitting the fixing part 12 of the contact terminal 10 into the side wall 2 from below.

  As shown in FIG. 3, the elastic portion 18 of the contact terminal 10 includes a first terminal portion 13 extending from the lower end portion of the fixing portion 12 toward the inside of the housing 1, and a first bent portion 14 extending from the first terminal portion 13. A second terminal portion 15 extending toward the upper side of the side wall 2 of the housing 1 via the second terminal portion 15 and a third terminal portion extending from the second terminal portion 15 toward the inner upper side of the housing 1 via the second bent portion 16. The connecting portion 11 is formed at the tip of the third terminal portion 17.

  The housing 1 also has a suction surface 7 for automatic mounting at the center of the bottom surface 3 as shown in FIG. The housing 1 is mounted by adsorbing and holding the bottom surface 3 of the housing 1 by an adsorption nozzle of a mounting machine, and placing the housing 1 on a circuit board (not shown).

  A housing portion 9 that houses the lower portion of the contact terminal 10 is provided around the suction surface 7. The accommodating part 9 has an opening 9 a for projecting the connecting part 11 of the contact terminal 10 upward in the upper part.

  The suction surface 7 has an auxiliary suction surface 8 that protrudes toward the opening 9 a of the housing portion 9. The auxiliary suction surface 8 is formed flush with the suction surface 7 as shown in FIG. As shown in FIG. 2, the auxiliary suction surface 8 is formed so as to protrude from the suction surface 7 toward the side wall 2 of the housing 1, and forms a flat surface with the suction surface 7 together with the portion between the auxiliary suction surfaces 8. That is, the mounting surface for mounting can be increased by one size. Thereby, even if the contact terminal 10 is arrange | positioned in the bottom part of the housing 1, it can be set as the housing 1 which can respond to automatic mounting.

  Further, since the auxiliary suction surface 8 is formed in a bowl shape, the contact terminal 10 can be disposed also below the auxiliary suction surface 8, and the length of the elastic portion 18 can be increased. Thereby, since the elastic force of the elastic part 18 can be strengthened, the connection part 11 of the contact terminal 10 and the contact part of the electric component 50 can be made to contact reliably.

  The auxiliary suction surface 8 is formed so that its tip protrudes to the vicinity of the position at the height of the opening 9a of the housing portion 9 when the tip of the connection portion 11 of the contact terminal 10 moves downward. For this reason, the suction surface for mounting can be enlarged without obstructing the downward movement of the connecting portion 11 of the contact terminal 10.

  Further, the contact terminal 10 in this embodiment is fixed to the housing 1 by press-fitting the fixing portion 12 into the insertion portion 5 from the lower side with respect to the side wall 2 of the housing 1. The terminal 10 can be easily attached.

One folded portion 14 is arranged. That is, the connecting portion 11 is disposed closer to the side wall 2 of the housing 1 than the first bent portion 14. For this reason, when the connection part 11 of the contact terminal 10 is pushed downward by the insertion of the electric component 50, the movement of the connection part 11 in the inside and outside of the housing 1 by the first bent part 14 and the second bent part 16 can be canceled. The connecting portion 11 can be moved substantially vertically downward. Thereby, while being able to ensure the contact of the connection part 11 and the contact part of the electrical component 50, generation | occurrence | production of malfunctions, such as a deformation | transformation of the connection part 11, and a failure | damage, can be prevented.

  As mentioned above, although embodiment of this invention was described, application of this invention is not restricted to these embodiment, It can apply variously within the range of the technical idea. For example, the number of contact terminals 10 juxtaposed in the housing 1 is not limited to the present embodiment, and may be more or less.
