らの欠点を除くためになされたものである。These have the following drawbacks. (A) In the case of using a screw, it is often screwed from the back of the board, so there is a problem in fixing the nut, it is complicated because a nut and screw and a jig such as a drag bar is required, and during reflow. I needed to hold down weights to prevent it from rising and the head of the screw came out of the board, which was an obstacle. (B) In the case of using a solder tab, the board often warps during reflow or separates from the board due to thermal deformation of the electronic component itself, so weights are used in the reflow process to prevent lifting, or for tabs on the board. Since the pattern is required, the effective use range of the substrate is narrowed. The present invention has been made to eliminate these drawbacks.

Provided on the lower surface of the body (2). (C) A push pin (1) having a flat upper portion and a cylindrical lower portion provided with fall prevention protrusions (9) in the circumferential direction is fixed to the post through hole (7) so as to be slidable. According to the present invention, in the case of using this product with the above-mentioned structure, the post (3) is formed by aligning the electronic component having the push pin (1) on the body (2) with the fixing hole of the substrate. It penetrates through the fixing holes in the board and is lightly aligned. After that, by pushing the push pin (1) from above, the tip of the post (3) breaks the edge of the fixing hole of the substrate or moves forward while deforming the tip of the push pin (1), and strongly presses the fixing hole of the substrate. Fixing is completed by doing. Also, the place where the post finally contacts the fixing hole of the substrate may be roughened or a protrusion may be provided. The push pin (1) may be fixed to the post (3) by a method other than the protrusion.

くしたり突起を付けてもよい。A third embodiment of the invention will be described below with reference to FIGS. 5, 6 and 7. (A) An electronic component, for example, a body (2) of a header body for a memory card is provided with a through hole (4). (B) A collar (6) is provided on the upper side so that it can be fixed to the through hole (4), and a slit (5) of an appropriate length is symmetrically or asymmetrically provided at the tip along the axial direction, and a lower proper side is provided. A post (3) having a post through hole (7) having an internally threaded portion (10) that has been processed at various positions is press-fitted into the body (2). (C) Tighten the push pin (1) having a male thread on the outer periphery to the position where the post through hole (7) has a thread. According to the present invention, when the present product is used with the above-described structure, by aligning the electronic component having the post (3) and the push pin (1) on the body (2) with the fixing hole of the substrate,
The posts (3) penetrate through the fixing holes in the substrate and are lightly aligned. After that, by further rotating the push pin (1), the tip of the post (3) goes over the unprocessed part of the screw thread and moves forward to open the tip of the post (3) and strongly press the fixing hole of the substrate. Fixing is completed by. Alternatively, as shown in FIGS. 6 and 7, the post (3) may be integrated with the body (2) and self-tapping may be performed without performing female thread processing. The post may be roughened or provided with a protrusion at a place where the post finally contacts the fixing hole of the substrate.

しないので取り扱いが容易である(B) Since the post can be machined so that its outer shape is smaller than the hole of the board, the position of the post can be roughly aligned easily. (B) Push pin is pushed in or turned to open the post or push pin is cut in to easily and firmly connect to the board, so there is no need to prepare screws separately, and soldering of electronic component tails, etc. Position alignment of parts becomes possible almost mechanically. (C) Since it can be firmly connected to the board, it can be prevented from floating due to warpage of the board during reflow, and jigs such as weights are not required. As a result, floating of the soldered part can be prevented and reliability is high, and A product with good workability can be manufactured. (D) By adjusting the length of the post, it is possible to firmly fix the post by sticking it out from the base plate as in the conventional case. (E) The post is integrally machined on the body and eccentric has a simple shape. Because the tip is not chipped during transportation or handling, it is easy to handle
