Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a mold fixing device for preventing the hook from being lost.

[Prior Art] Conventionally, a fixing device for this type of mold will be described with reference to FIG.

In the drawing, reference numeral 1 denotes a hook vertically provided from a mold 2, and the hook 1 has a step portion 3 formed on a side surface thereof. Then, the hook 1 is inserted into the locking hole 5 formed in the substrate 4, and the stepped portion 3 of the hook 1 is locked to the edge of the locking hole 5 on the back surface of the substrate 4, and the mold 2 is fixed. It is fixed to the substrate 4.

[Problems to be Solved by the Invention] In the conventional mold fixing device described above, the hook is inserted into the locking hole of the substrate or the like to fix the hook.

However, when the mold is mounted on a substrate or the like, the tip of the hook protrudes to the back surface, so that external force is applied to the tip of the hook when the parts are transported, and the hook is missing and the mold is damaged. The fixation may become unstable and the quality may be deteriorated.

Therefore, there is a technical problem to be solved in order to prevent the hook from dropping and stabilize the mold fixing, and to improve the quality, and the present invention aims to solve the problem. .

[Means for Solving the Problems] The present invention has been proposed in order to achieve the above-mentioned object. A hook is hung vertically on a mold, and the hook is inserted into a locking hole or the like of a substrate to be locked. In the mold fixing device for fixing the mold to the substrate or the like, the mold fixing device is characterized in that a guard wall is provided so as to face the side surface of the hook from the mold.

[Operation] In this invention, a guard wall is vertically provided from the mold so as to face the side surface of the hook. Then, the mold is fixed to the substrate by inserting the hook and the guard wall into the locking hole of the substrate or the like and locking the hook. At this time, the tip portion of the hook projects to the back surface of the substrate or the like, but the guard wall protects the hook.

[Embodiment] An embodiment of the present invention will be described below in detail with reference to FIGS. 1 to 4 of the attached drawings.

In the figure, 10 is a plug unit attached to a computer or the like, and is formed so that the socket 12 of the cable 11 can be connected from the upper surface of the plug unit 10. Contact pins 14, 14 ... Are fixed to the mold 13 of the plug unit 10, and lower ends of the contact pins 14, 14 ... Are connected to the circuit board 15. In the figure, 16 is a circuit board 15.
It is an LED attached to. Further, 17 is a connector mounted on the circuit board 15, and the circuit board is connected by the connector 17.
Connect 15 and other components.

Further, hooks 18, 18, ... Are vertically provided on the mold 13, and the hooks 18, 18, ... Are locked to the circuit board 15 and the mold 13 is mounted. As shown in FIG. 2, the hook 18 is integrally formed from the lower end of the mold 13 and hung vertically, and is given an elastic force. Further, as shown in FIG. 3, a step portion 19 is formed by projecting the outer surface of the front end portion of the hook 18. Further, a guard wall 20 is vertically provided at the lower end of the mold 13, and the guard wall 20 is formed in a U shape so as to face the side surface of the hook 18 as shown in FIG. Then, the side surface of the hook 18 having the stepped portion 19 is opened so that the hook 18 is in the third position.
It is configured so that it can rotate in the left-right direction in the figure. on the other hand,
The outer surface of the guard wall 20 is cut inward at the lower end to form a seat 21.
Is formed.

When the mold wall 13 is pressed against the circuit board 15 by facing the guard wall 20 and the hook 18 above the locking hole 22 of the circuit board 15, as shown in FIG. Is inserted into the locking hole 22, the insertion is stopped when the seat 21 abuts on the upper surface of the circuit board 15, and the stepped portion 19 of the hook 18 is the edge of the locking hole 22 on the back surface of the circuit board 15. Engage the part. Therefore, the mold 13 is fixed to the circuit board 15.

In the state where the mold 13 is mounted, the tip of the hook 18 projects from the back surface of the circuit board 15, but the guard wall 20 prevents external force from being applied to the hook 18. or,
Even if an external impact is applied to the surface of the hook 18 provided with the step portion, the guard wall 20 prevents the hook 18 from rotating and prevents the hook 18 from being chipped. Further, since the guard wall 20 does not rotate, etc., the positioning at the time of mounting is easier and the rattling of the mold 13 against the circuit board 15 is prevented as compared with the case where it is fixed only by the hook. To do. Further, the guard wall 20 protruding from the back surface of the circuit board 15 protects the contact pins 14, 14 ... And other terminals shown in FIG. Further, the guard wall 20 protects the hooks 18 when the mold 13 is conveyed or when the mold 13 is released from the mold.

It should be noted that this invention can be modified in various ways without departing from the spirit of this invention, and it goes without saying that this invention extends to the modified version.

[Advantage of the Invention] In this invention, the hook for fixing the mold is protected by the guard wall, so that the hook is prevented from being damaged.

Therefore, it is a device having practical effects such as stable fixation of the mold and contribution to improvement of quality.
