Description

Technical Field

[0001] This utility model relates to the field of igniter manufacturing technology, specifically a structure suitable for automated line operation. Background Technology

[0002] As the core transformer device of the automotive ignition system, the coil igniter (i.e., ignition coil) uses the principle of electromagnetic induction to instantly boost the low-voltage electricity (about 12V) of the battery to a high-voltage electricity of 10,000-30,000 volts, driving the spark plug to ignite the air-fuel mixture in the engine cylinder, ensuring combustion, starting, and continuous operation. Its structure mainly includes a primary coil (thick enameled wire, 200-500 turns) and a secondary coil (fine enameled wire, 15,000-25,000 turns), and integrates a magnetic core, switching transistor, and insulation components. It achieves efficient voltage conversion through inverter technology, while also needing to cope with the challenges of harsh environments such as high temperature and moisture.

[0003] Existing igniters are not suitable for automated production lines and mostly require manual assembly, resulting in low production efficiency and poor accuracy. They are fixed by inserting a pin into a slot, which is unstable. During subsequent assembly, the plug mechanism is prone to detaching from the igniter housing.

[0004] Based on this, a structure suitable for automated line operation is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-5 As shown, a structure suitable for automatic line operation includes a plug mechanism 1 and an igniter housing 2. The plug mechanism 1 includes a conductive insert 101. Two primary inserts 103 and one secondary insert 104 are welded to the bottom of the conductive insert 101. An injection-molded plug 102 is injection molded on the outside of the conductive insert 101. Stabilizing mechanisms 3 are installed on both sides inside the igniter housing 2. Two first anti-mistake grooves 4 are symmetrically opened on the top of the igniter housing 2. A first anti-mistake block 5 is engaged inside each of the two first anti-mistake grooves 4. A primary winding housing 6 is fixedly connected between the two first anti-mistake blocks 5.

[0027] In this embodiment, the conductive plug 101 is first injection molded into an injection plug 102, and then the plug resistor 105 is welded to the conductive plug 101 to complete the assembly of the plug mechanism 1. Finally, the plug mechanism 1 is installed with the igniter housing 2. No tools are needed to lock it during the installation process, which is convenient for automatic line operation and greatly improves the production efficiency of igniters.

[0028] In one embodiment, such as Figure 2 and Figure 3As shown, the injection-molded plug 102 has a plug resistor 105 installed inside, and the plug resistor 105 is welded to the conductive plug 101. The injection-molded plug 102 has grooves 106 on both sides of its exterior, and the grooves 106 are adapted to the igniter housing 2. The top of the igniter housing 2, on one side of one of the first anti-foolproof grooves 4, has a secondary slot 7, and the secondary slot 7 is adapted to the secondary plug 104. The top of the primary winding housing 6 has two symmetrical primary slots 11, and the primary slots 11 are adapted to the primary plug 103. During the installation of the plug mechanism 1 and the igniter housing 2, the secondary plug 104 is inserted into the secondary slot 7, and the primary plug 103 is inserted into the primary slot 11, thereby completing the electrical connection with the primary coil and the secondary coil. Through the cooperation between the grooves 106 and the igniter housing 2, the plug mechanism 1 is not easily misaligned during installation, improving the installation accuracy and the quality of the igniter.

[0029] In one embodiment, such as Figure 4 and Figure 5 As shown, the stabilizing mechanism 3 includes a fixing block 31, which is fixedly installed inside the igniter housing 2. Two sliding grooves 32 are formed on one side of the fixing block 31, and sliding rods 33 are slidably installed inside each of the two sliding grooves 32. A locking block 34 is fixedly installed at one end of each sliding rod 33, and a chamfer 36 is formed on the top of the locking block 34. A reset assembly is installed on one side of the fixing block 31, and the reset assembly includes a spring 35, one end of which is fixedly installed on one side of the fixing block 31. The other end of the spring 35 is fixedly installed with the locking block 34. During the downward pressing of the plug mechanism 1, it first contacts the locking block 34. Due to the setting of the chamfer 36, the two locking blocks 34 move to both ends, the slide rod 33 slides inside the slide groove 32, and the spring 35 is compressed. When the plug mechanism 1 is fully installed inside the igniter housing 2, due to the reset action of the spring 35, the two locking blocks 34 move closer to each other, thereby locking and fixing the plug mechanism 1, which improves the stability of the installation of the plug mechanism 1, and does not require the use of tools, making it convenient for automatic line operation.

[0030] In one embodiment, such as Figure 3 As shown, the top of the first anti-misalignment block 5 is provided with a second anti-misalignment groove 8, and a second anti-misalignment block 9 is installed inside the second anti-misalignment groove 8. One end of the second anti-misalignment block 9 is fixedly connected to the secondary winding housing 10. An iron core is installed at the center point of the secondary winding housing 10. Through the cooperation of the first anti-misalignment groove 4 and the first anti-misalignment block 5, it is convenient to assemble the primary winding housing 6 with the igniter housing 2. Through the cooperation of the second anti-misalignment groove 8 and the second anti-misalignment block 9, it is convenient to assemble the secondary winding housing 10 with the primary winding housing 6. Finally, the iron core is installed with the secondary winding housing 10. The above structure prevents misalignment and improves the installation accuracy.

[0031] The above embodiment discloses a structure suitable for automatic line operation. First, the conductive plug 101 is injection molded into an injection plug 102. Then, the plug resistor 105 is welded to the conductive plug 101 to complete the assembly of the plug mechanism 1. The first anti-misalignment groove 4 and the first anti-misalignment block 5 facilitate the assembly of the primary winding shell 6 and the igniter shell 2. The second anti-misalignment groove 8 and the second anti-misalignment block 9 facilitate the assembly of the secondary winding shell 10 and the primary winding shell 6. Finally, the iron core is installed on the secondary winding shell 10. The above structure prevents misalignment and improves the installation accuracy.

[0032] During the installation of the plug mechanism 1 and the igniter housing 2, the secondary insert 104 is inserted into the secondary slot 7, and the primary insert 103 is inserted into the primary slot 11, thereby completing the electrical connection with the primary coil and the secondary coil. Through the cooperation of the groove 106 and the igniter housing 2, the plug mechanism 1 is less prone to misalignment during installation, improving the installation accuracy and the quality of the igniter. At the same time, during the downward pressing of the plug mechanism 1, it first contacts the locking block 34. Due to the setting of the chamfer 36, the two locking blocks 34 move to both ends, the slide rod 33 slides inside the slide groove 32, and the spring 35 is compressed. When the plug mechanism 1 is fully installed inside the igniter housing 2, due to the reset action of the spring 35, the two locking blocks 34 move closer to each other, thereby locking and fixing the plug mechanism 1, improving the stability of the installation of the plug mechanism 1, and eliminating the need for tools, which is convenient for automatic line operation.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
