BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chip component socket used when a chip component such as a chip resistor is mounted on a printed board.

[0002]

2. Description of the Related Art In recent years, computerization has advanced in various fields, and accordingly, diversification of specifications and miniaturization of parts are required. Also for circuit parts, it is becoming mainstream to use chip parts in order to cope with miniaturization.

[0003]

However, there is a problem in that mounting of the component is troublesome because the component is made into a chip and miniaturized. In other words, the current situation is that the progress of component mounters has not kept pace with the progress of components. Moreover,
When parts are made into chips and downsized, there is a problem that it takes time and effort to replace parts and perform maintenance.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a chip component socket which allows easy mounting, rearrangement, maintenance and the like of components. is there.

[0005]

According to the present invention, in order to achieve the above object, a frame-shaped socket main body for accommodating a chip component therein, and an upper part of the socket main body are slidably mounted in a lateral direction and mounted. A chip retainer that elastically contacts the upper surface of the mounted chip component, contacts the terminals of the mounted chip component, and implants a plurality of spring-like contacts that are soldered during mounting on the printed circuit board into the socket body. I am doing it.

In order to form a wiring pattern under the socket body, a stopper may be formed at the bottom of the socket body for floating the chip component from the printed board. Further, in order to facilitate the removal of the chip component, it is preferable to form one step lower portion for removing the chip component at one or both ends of the socket body.

Further, it is preferable to provide a fixing means for fixing the chip holder to the position of the center of gravity of the entire chip when the chip component is not mounted so that the chip component socket can be mounted on a printed circuit board or the like by using the component mounter. Furthermore,
When mounting a chip component socket on a printed circuit board using a component mounter, the size of the central part of the chip holder should be at least as large as the suction surface of the component mounting nozzle of the component mounter. It is necessary to.

[0008]

The present invention has the above-mentioned configuration,
The socket main body is mounted on a printed circuit board in advance, and then the chip parts can be detachably mounted on the socket main body. Here, if the socket body has a structure that can be mounted by a mounter, chip components of any shape can be mounted. Moreover, by sliding the chip holder, the chip parts can be removed, and the reassembly and maintenance can be easily performed.

[0009]

1 to 3 show an embodiment of the present invention. In this embodiment, a chip component socket (hereinafter, simply referred to as a socket) in which the chip resistor 4 is mounted is shown. As shown in FIG. 1, this socket has a chip resistor 4
And a chip holder 2 for elastically contacting the upper surface of a chip resistor 4 mounted on the upper part of the socket body 1 slidably in the lateral direction.

A plurality of contacts 3 for contacting the terminals 4a of the chip resistors 4 mounted on the socket body 1 are planted. The socket body 1 is formed with slide grooves 5 running laterally from the right end to the substantially central portion at the upper portions of both side surfaces. The tip retainer 2 is made of an elastic material and has a U-shaped cross section, and both side portions are further bent inward to form an engagement piece 2a. Therefore, the engaging piece 2a is engaged with the slide groove 5 and is attached to the socket body 1 so as to be slidable in the lateral direction. Then, a resilient contact portion 2b is formed which resiliently contacts the chip resistor 4 mounted by forming a spherical recess in the center of the upper surface. In addition, in order to prevent the chip resistor 4 from floating and coming off, the upper surface is formed in a convex shape in the central portion to sufficiently close the opening of the socket body 1.

Here, the chip holder 2 has a chip resistor 4
When the chip resistor 4 is not attached, it is moved to the right end as shown in FIG. 1A, and when the chip resistor 4 is attached, it is moved to the center as shown in FIG. 3A. Therefore, in order to position the chip holder 2, a convex portion 1a is formed on the upper surface of the socket body 1. The contact 3 is formed of a conductive material having a spring property, and as shown in FIG.
One end is formed in a U shape having a downward opening, and the tip end portion is exposed inside the socket body 1, and insert molding is performed in both side wall portions of the socket body 1. Then, the other end is extended laterally from the bottom surface, and this extended portion is used as a terminal when the socket body 1 is mounted on the printed board.

Here, in this embodiment, the contacts 3 respectively inserted into the both side walls are arranged in a staggered manner, and the terminals 4a of the chip resistors 4 are elastically sandwiched. By disposing a plurality of contacts 3 in this way, a plurality of chip resistors 4 or chip resistors 4 having different terminal shapes can be mounted. In addition, as described above, the contact 3
By arranging the zigzags in a zigzag manner, chip components such as transistors having three terminals arranged in a triangular shape other than the chip resistor 4 can be mounted. Therefore, in the case of a socket in which only the chip resistor 4 is symmetrical, the contacts 3 may be symmetrically arranged in each side wall.

The chip resistor 4 of the socket body 1 is also provided.
The left end of the mounting portion is recessed in a substantially semicircular shape, and this recess 5 is used to remove the chip resistor 4. Hereinafter, a method of mounting the chip resistor 4 using the socket of this embodiment will be described. The socket body 1 is aligned with the land of the printed board and soldered, and fixed on the printed board. At this time, the tip holder 2 is slid to the right end of the socket body 1 as shown in FIG.

Next, the chip resistor 4 is placed in the socket body 1 as shown in FIG. Then, the tip holder 2 is slid to the left and moved to the central portion of the socket body 1. As a result, the chip resistor 4 is pressed by the chip presser 2. Since the chip resistor 4 is pressed by the chip retainer 2 in this manner, the chip resistor 4 does not float due to vibration or impact, and the contact stability is improved.

By the way, in the conventional device having a structure in which parts are retrofitted, a pressing member, which is a separate part, is usually attached so as to prevent the parts from floating due to vibration or shock. Further, the pressing member has a structure that is attached to the socket body by engagement of hook claws or the like. However, with such a structure, it is necessary to remove the pressing member that engages with the main body of the apparatus, so that it takes time and trouble to remove the parts, and since it is a separate member (can be removed), the pressing member is removed. May be lost.

In this respect, in this embodiment, since the chip holder 2 is integrally attached to the socket body, there is no fear of loss, and the chip resistor 4 can be removed by sliding the chip holder 2 and removing the chip resistor 4. Has the advantage that it does not take time. In addition, this removal is done with the tip holder 2
The chip resistor 4 can be removed by sliding, and inserting a jig having a thin tip (for example, one having a shape like a mechanical pencil tip) into the concave portion 5 formed in the socket body 1 and prying.

By the way, it is preferable to provide the following structure in addition to the above structure. This structure is shown in FIG. That is,
A stopper 6 for floating the chip resistor 4 from the printed circuit board is formed on the bottom of the socket body 1. When the stopper 6 is formed, the terminals of the chip resistor 4 do not come into contact with the printed circuit board, so that a wiring pattern can be formed under the socket, and space saving and mounting surface efficiency can be achieved.

By the way, in the above-described case, the jig 5 having a thin tip was inserted into the recess 5 formed in the socket body 1 and the chip resistor 4 was removed by prying, but as shown in FIG. If one end of the formed socket body 1 is formed as a lower stepped portion 1b and the end portion of the chip resistor 4 can be hooked and pushed up by a finger as shown in FIG. 9, the chip resistor 4 can be removed more easily. It is convenient to do.

Further, it is preferable that this type of socket can be mounted on a printed circuit board or the like by a component mounting machine. Therefore, in order to enable mounting by the component mounter as described above, the convex portion 1a on the center side is formed so that the chip holder 2 can be fixed at the position of the center of gravity of the whole when the chip resistor 4 is not mounted. The size of the central portion of the chip holder 2 may be formed to be at least the size of the suction surface of the component mounting nozzle of the component mounter (the size of the suction surface is indicated by the hatched line in FIG. 8). .. If you do this,
The chip holder 2 can be mounted on a printed circuit board or the like by grasping it with the nozzle of the component mounter, and the socket can be easily mounted.

Although the above description has been made on the chip resistor 4, it goes without saying that a capacitor, a transistor, or an IC is used.
It goes without saying that it can also be applied to the like.

[0021]

As described above, according to the present invention, the frame-shaped socket main body for accommodating the chip parts therein, and the upper surface of the chip parts mounted slidably in the lateral direction on the upper part of the socket main body are mounted. The socket body consists of contacting chip holders, contacts the terminals of the chip components to be mounted, and has multiple spring-like contacts that are soldered during mounting on the printed circuit board. The chip component can be mounted on the printed circuit board in advance, and then the chip component can be removably mounted on the socket body. Therefore, if the socket body has a structure that can be mounted by a mounter, chip components of any shape can be mounted.
Moreover, by sliding the chip holder, the chip parts can be removed, and the reassembly and maintenance can be easily performed.

If a stopper for floating the chip component from the printed circuit board is formed at the bottom of the socket body, a wiring pattern can be formed under the socket body, which saves space and improves the mounting surface efficiency. be able to. In addition, if one step lower part is formed at one or both ends of the socket body to remove the chip part, expose the end part of the chip part and push up this part with your finger to remove the chip part.
