Abstract
The invention relates to a method for integrating an ignition coil split module, wherein a split module, a module bracket and a plug are mainly provided; the module bracket is in a shape of flat plate; two small eudipleural blocks are arrayed at the middle; strip struts the lateral surfaces of which are triangular extend from two ends of one side close to the plug of the module bracket; the tail ends of the struts are in a trapezoid shape; and two trapezoid grooves are formed at the rear part of the plug. During integration, the method comprises the following steps of: firstly, clamping split modules into two small blocks of the module bracket; secondly, inserting the tail ends of the struts of the module bracket into the trapezoid grooves at the rear part of the plug; and finally carrying out micro arc spot welding and closing argon gas by delaying 0.5 second after arc blowout so as to protect welding spots to cool and condense. Compared with the conventional method for integrating the ignition coil split module, the invention has the advantages of high micro arc spot welding efficiency, no lead in the welding process, environmental protection and no harm to human body; in addition, since the split module and the plug form a whole by the module bracket, the circuit conduction can be ensured.
Description
Technical field
The present invention relates to a kind of module integrated approach, the split type module integrated approach of particularly a kind of ignition coil.
Background technology
The split type module of ignition coil integrated normally at first is installed on plug on the housing, and split type module places in the housing; Secondly, pick up split type module and the inserted sheet of this module is docked with the inserted sheet of plug, implement soldering with electric iron at the inserted sheet joint with tweezers; The motionless 3-5 in postwelding inserted sheet joint holding position second is to treat the solder joint cooled and solidified.Its problem is to use lead to cause damage to human body and environment in the soldering process; The space is narrow and small in the housing, makes inserted sheet butt joint hand-manipulated and soldering may have the not firm and rosin joint of solder joint, and split type module only depends on solder joint to rely on to be suspended in the housing, inserted sheet may take place dock and get loose, and causes loose contact, not conducting of ignition coil circuit.
Summary of the invention
The objective of the invention is to propose a kind of safety, environmental protection, efficient and guarantee the split type module integrated approach of ignition coil of circuit turn-on.
Technical scheme of the present invention is achieved in that the split type module integrated approach of described ignition coil, mainly comprise split type module, module bracket and plug, module bracket is tabular, the middle part is arranged with symmetrical two blockages, respectively extending near the two ends, one side of plug, the side be leg-of-mutton strip pillar, it is trapezoidal that post tips is, and there are two trapezoidal grooves at the plug rear portion.When integrated, at first split type module card in two blockages of module bracket; Secondly the post tips of module bracket is inserted on the trapezoidal groove of plug; Implement micro-arc spot welding at the inserted sheet joint of split type module and plug at last, welding parameter is set as follows table:
| Welding method | Welding current (A) | Nozzle diameter (mm) | Tungsten electrode diameter (mm) | The spot welding time (ms) | Working gas flow (L/min) | Shield gas flow rate (L/min) |
| Micro-arc spot welding | ??16～24 | ??Φ1.2 | Cerium tungsten Φ 0.8 | ??45～60 | ??Ar0.5 | ??Ar0.5 |
Delay was closed argon gas in 0.5 second with protection solder joint cooled and solidified after the blow-out.Split type module, module bracket and plug form in the housing of packing into after the integral body.
The invention has the beneficial effects as follows: micro-arc spot welding efficient height, welding process is not leaded, environmental protection and harmless; Module bracket makes split type module and plug form integral body, avoids the circuit loose contact.
The invention will be further described below in conjunction with the drawings and specific embodiments.
