Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a fuse for an automatic insertion machine for automatically mounting a circuit connection terminal leg between tapes to a predetermined position of the automatic insertion machine and mounting it on a substrate. Regarding clips.

(Prior Art) Conventionally, as shown in FIGS. 5 and 6, a fuse clip that holds both ends of a cylindrical fuse tube mounted on a substrate is located above both edges of the base portion 1 which are arranged to face each other. A pair of holding springs 2 and 2 are projected, and the end portion of the fuse tube 3 is held between the holding springs 2 and 2, and the holding spring projecting side edge portion of the base portion 1 is disposed at an opposite edge orthogonal to the holding spring protruding side edge portion. In general, a pair of terminal legs 4, 4 are integrally projected from the portions 1a, 1a to the back surface side.

When mounting this fuse clip on the board, it has been attempted to use a general-purpose automatic insertion machine used for mounting resistors, capacitors, diodes, etc., as shown in FIG. Sandwiched between the tapes 5 and 5 and held by the tape at regular intervals, and fed into the automatic insertion machine in a fixed orientation as shown in FIG. 8, and the terminal legs 4 and 4 are cut to a predetermined position on the substrate 7. The terminal legs 4 and 4 are inserted into the through holes of the substrate 7 by moving them down and pushing them down with the push rod 8.

(Problems to be Solved by the Invention) The tip surface of the push rod 8 of this conventional general-purpose automatic insertion machine corresponds to the general shape and size of many electronic parts, and therefore, is not shown in FIGS. As shown in the figure, the side parallel to the feeding direction of the tape 5, that is, the direction a side connecting the pair of terminal legs is long, and the direction b side orthogonal thereto is short.

Therefore, if the conventional fuse clip described above is to be mounted on this automatic insertion machine, as shown in FIG. 7, the fuse springs 2 and 2 face each other in a direction orthogonal to the center line direction of the clamped fuse tube. Since the narrow width direction a is oriented in this direction, the tip of the push rod 8 fits between the two holding springs 2, 2 or only the holding spring 2 on one side is pushed and pressed in an inclined state. There is a problem that insertion defects frequently occur, which causes a decrease in the operating rate of the automatic insertion machine.

In view of such conventional problems, the present invention has an object to provide a fuse clip which does not cause defective insertion without changing the design of a general-purpose automatic insertion machine.

(Means for Solving the Problem) The gist of the present invention for solving the above-mentioned conventional problems and achieving the intended purpose is that from the opposite edges of the base portion to the surface side thereof. A fuse clip having a fuse holding spring that is raised in one piece and holds one end of a cylindrical fuse tube and is opposed to each other, and a pair of terminal legs for circuit connection are integrally projected on the back side of the base. In the above, the terminal legs are projected so as to be opposed to each other under both edges of the base portion on the side parallel to the axial direction of the fuse tube held by the fuse holding spring, and the both terminal legs are arranged between two transfer tapes. It lies in a fuse clip for an automatic insertion machine, which is characterized in that it is held between.

(Operation) In the fuse clip of the present invention, since the pair of terminal legs are projected in the same opposing direction as the opposing direction of the fuse holding springs facing each other, when taping this for the automatic insertion machine, the feeding direction of the fuse clip is increased. Side is sent in the state of facing the fuse holding piece spring, and when inserting into the board using a general-purpose automatic inserter that uses a push rod with a long end face shape in the feeding direction, the end face of the push rod faces The fuse holding pieces in contact with each other always come into contact with the upper ends of the fuse holding pieces in a state of straddling each other, thereby eliminating the occurrence of defective insertion.

(Embodiment) Next, an embodiment of the present invention will be described with reference to FIGS.

1 and 2 show a fuse clip according to the present invention. The fuse clip 10 has two pairs of fuse holding springs 12a, 12a, 12b, 12b protruding upward from a pair of edges of the base 11 facing each other. Each of the fuse holding springs 12a, 12b has an arc-shaped holding recess 13a, 13b in which the center height position is recessed on the facing surface side.

Below the opposing edges of the side of the base 11 on which the holding springs 12a, 12b are projected, the terminal legs 14a, 14 are provided at substantially central positions of the respective edges.
b is integrally projected.

This fuse clip 10 is formed by punching out a conductive metal plate material and molding each part by pressing at the time of manufacture, and the fuse holding spring 12 is continuous with the base portion 11.
The terminal legs 14a and 14b are punched and molded between a and 12a and between 12b and 12b, and the fuse holding springs 12a and 12b are bent and erected on the front surface side of the base 11 and the terminal legs 14a and 14b on the rear surface side.

 In the figure, 15 is a stopper tongue.

When the fuse clip 10 having the above-described structure is applied to an automatic insertion machine, when both terminal legs 14a and 14b are held between the tapes 5 and 5 as shown in FIGS. The direction and the opposing direction of the fuse holding springs 12a and 12b are the same, and the longitudinal direction of the end face of the push rod 8 is the same direction. Therefore, even if there is some variation in the upper end spacing of the fuse holding springs 12a, 12b that face each other when being pushed by the push rod 8, the lower ends of the push rods 8 will face the upper ends of the opposite fuse holding springs 12a, 12b. It will always be pressed.

(Effects of the Invention) As described above, the fuse clip for an automatic insertion machine of the present invention is mounted on the automatic insertion machine because the pair of terminal legs are projected in the same facing direction as the facing directions of the fuse holding springs facing each other. Therefore, when taping the terminal leg, the tape feeding direction and the facing direction of the fuse holding spring are the same, and even if the conventional general-purpose automatic insertion machine is used as it is, the push rod is always pushed in completely. As a result, there is no pressing failure, and the same general-purpose automatic insertion machine ensures that automatic insertion is performed like other electronic components, and efficient automation is achieved.
