The PIN 122 has a bar shape, and the shape of the PIN 122 may be set as needed, for example, the PIN 122 has a flat shape or an L shape (the PIN 122 has a flat shape after press molding, and has an L shape after being mounted on the housing 11 of the electronic component case, and the PIN 122 may have other shapes as needed).

Each PIN 122 has a soldering PIN 123 and a connecting PIN 124, the soldering PIN 123 is used for soldering with a circuit board, the connecting PIN 124 is used for electrically connecting with a lead, i.e. the PIN 122 and the lead can allow current to pass through, and the connecting PIN 124 can be larger than the width of the PIN 122 at other positions.

The welding leg 123 is directly or indirectly connected to the edge strip 120, and the connection manner may be an integral molding, etc.

The PIN 122 and the edge strip 120 may be produced simultaneously, for example, by stamping the sheet material using a stamping technique, etc., so that the excess portion, such as the edge strip 120, may be removed after the assembly process is completed for ease of manufacture and use.

Referring to fig. 3, the terminal pin 124 is provided with a terminal lug 125, the terminal lug 125 is provided with a wire-locking groove 126 for accommodating a lead, the depth of the wire-locking groove 126 can be larger than the diameter of the lead, generally, the diameter of the lead is about 0.08-0.12mm, there are one or two winding wires, the width of the wire-locking groove 126 can be set to 0.24-0.30mm, and the width of the wire-locking groove 126 can be adjusted appropriately according to the diameter of the lead.

The shape of the wire-locking groove 126 is not limited, and may be, for example, U-shaped, V-shaped, semicircular, irregular, etc., and the main function of the wire-locking groove 126 is that, after the end of the lead is clamped at the bayonet 130, the relative position of the lead and the wire-locking groove 126 is fixed, the lead does not slide relative to the wire-connecting pin 124, and the welding by the worker is facilitated.

Of course, the terminal pin 124 may be bent, and the lead may be held and fixed after the terminal pin 124 is bent.

In this embodiment, the ridge line groove 126 is U-shaped, the ridge line groove 126 can be divided into three parts, namely, an end part, a middle part and a bottom part, the distance between the two end parts of the ridge line groove 126 is gradually reduced from outside to inside, the distance between the middle parts is unchanged, and the bottom part adopts a circular arc structure. This design allows the lead to be easily inserted into the threshold slot 126.

Referring to fig. 4-6, the state of the bonding legs 124 before and after being bonded is schematically illustrated, and the bonding legs 124 can hold the leads after being bonded.

The above-mentioned "from outside to inside" refers to a direction from the opening of the ridge line groove 126 to the groove bottom.

During the production process, the following matters need to be noted: 1. the four-color wire needs to be twisted, and the number of twisted sections needs to be strictly controlled according to 1inch of 18 sections; 2. the winding rings can not be overlapped in a crossed way, and have the phenomena of multiple turns, less turns, copper wire skin breaking and the like; 3. when winding, the magnetic ring needs to be pressed to the bottom of the CASE and can not be suspended, and the PIN1 PIN position is noticed; 4. when winding, a single wire is wound with PIN3-4TS, and a stranded wire is wound with PIN2-3 TS; 5. the machine is a lead-free environment-friendly product, and all processes are carried out according to the lead-free product manufacturing process control; 6. before the product is on line, the first piece is manufactured to be confirmed to be correct, and then the product can be put into production; 7. leaving 12 blank spaces before banding, and leaving 15 blank spaces after banding; 8. wrapping the protective belt for one turn after finishing the belt beating; 9. before being packed with a belt reel, the bag is wrapped by a composite belt. Then, pumping out the air in the bag by a vacuumizing air extractor, and buckling and sealing the composite bag by the vacuumizing air extractor; 10. after the tape is wound, the upper and lower covers are sealed at the arc opening by using sealing glue (or paper tape).

The steps can be added, deleted, modified and adjusted according to the requirements.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
