Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spacer for an electronic component, which is used in combination with a desired electronic component such as an LED numeral display in which an LED (light emitting diode) is used to form 8 segments or 7 segments. And electronic components.

[0002]

As is well known, a large number of electronic components such as IC chips are standardized in size, and desired components can be obtained by directly gripping the electronic components by an automatic mounter. It can be automatically mounted on the site. However, for example, in the case of an LED display device having 8 segments or the like formed by LEDs, the positional accuracy of the leads provided in the LED display device may be poor, and the LED display device is directly gripped by the automatic mounter. Therefore, the lead may not be accurately aligned to the desired mount position. Therefore, it has been difficult to automate the mounting operation of the LED display.

Therefore, the applicant of the present application corrects the position of the lead of the LED display by combining the LED display and a predetermined spacer as a means for solving the above-mentioned problems, and the position accuracy of the lead is corrected. Inspired by the technical idea of increasing the. If it is possible to improve the position accuracy of the LED display leads by combining the LED display with a spacer, hold the LED display together with the spacer by the automatic mounter, and then appropriately move the LED display to the desired part. Can be mounted,
Mounting work can be automated.

However, as described above, when the LED display device is combined with a predetermined spacer, it is not possible to surely couple the both by simply fitting them together, and it is difficult to handle them. Occurs. Therefore, as a means for eliminating this, a means for adhering the LED display and the spacer with an adhesive can be considered.

However, if the adhesive is used in this way, the adhesive may adhere to the leads of the LED display, resulting in a defective product. In addition, LE on the upper surface side of the spacer
If an adhesive agent is interposed between the D display and the D display when they are fitted to each other, the LED display may rise from the spacer. If such a rise occurs, a large error occurs in the height dimension when the LED display is mounted on a desired portion, which is not appropriate.

The present invention has been devised under such circumstances, and when a desired electronic component is fitted into a spacer and both are combined, an adhesive is applied to the lead of the electronic component. An object of the present invention is to make it possible to appropriately combine the both without causing improper adhesion or a problem that the electronic component floats up from the spacer.

On the other hand, as the electronic component 2, for example, 8 segments 24 (or 7 segments) of LEDs are used.
An LED display device such as an LED number display device configured as described above is adopted. Further, notch-shaped concave step portions 29, 29 are provided on the upper portions of the left and right end portions of the electronic component 2. These concave step portions 29, 29 correspond to an example of the engaging portion according to the present invention, and when the electronic component 2 is fitted into the concave portion 13 of the spacer 1, the first portion of the spacer 1 is inserted. It is a portion for engaging each claw portion 12A of the hook-shaped projection 12, 12.

Next, the operation of the electronic component spacer 1 and the electronic component 2 having the above-described configurations will be described.

First, the spacer 1 is used in combination with the electronic component 2, and the electronic component 2 is fitted into the recess 13 of the spacer 1 as shown in FIGS. 2 and 3. In this way, the electronic component 2 is mounted on the recess 13

It will be shipped to the user side as it is. Alternatively, it is transferred to the next step.

As described above, if the tips of the leads 20 of the electronic component 2 are set in an accurate arrangement using the spacers 1, as shown in FIG. It is possible to accurately correspond to the formation position of the hole portion 31 for lead connection of the motherboard 3. Therefore,
Even when the spacer 1 and the electronic component 2 are gripped by using an appropriate mechanical device, this mechanical device allows the leads 20 of the electronic component 2 to be inserted into the lead connection holes 31 of the motherboard 3. It can be easily and accurately positioned and inserted.

Along with this, if the second hook-shaped projections 16 and 16 of the spacer 1 are inserted into the predetermined holes 30 and 30 of the motherboard 3, the claw portions 16A of each hook-shaped projection 16 are inserted into the motherboard. 3 can be engaged with the back side of the spacer 3, and the spacer 1 can be fixed and locked on the motherboard 3. Therefore, after that, the motherboard 3

It is possible to target various electronic components other than the LED display.

Further, the specific structure of each part of the electronic component spacer according to the present invention is not limited to that of the above embodiment, and various design changes are possible. For example, as the locking means for locking the electronic component, it goes without saying that a locking means having a different structure from the hook-shaped projection may be adopted.

Further, as means for locking the electronic component to the spacer, the concave step portion 29,
It is not necessary to provide an engaging portion such as 29, and for example, the locking means of the spacer is engaged with the upper surface portions (shoulder portions or corner portions) of both ends of the electronic component in which the concave step portion 29 and the like are not provided. You may do it. Further, the electronic component spacer according to the present invention is not necessarily limited to one for improving the positional accuracy of the leads of the electronic component.
