Abstract
The utility model discloses an insulation partition shelf of an ignition coil. The insulation partition shelf comprises a shelf body made of engineering plastics, wherein the shelf body is in U shape; connection holes are formed in two ends of the shelf body; raised parts are arranged in the middle of the inner side surface of the shelf body; a high voltage wiring terminal fixing part is arranged in the middle of the outer side surface of the shelf body; a mounting position on the partition shelf is provided for the wiring terminal, so that the wiring terminal is firmly mounted; and insulating resin can be filled in the inner side of the partition shelf, and because an outer frame is provided for filling the insulating resin, the insulating resin is effectively prevented from being cracked.
Description
Technical field
The utility model discloses a kind of ignition coil insulation separation frame, be specifically related to a kind of insulation separation frame that prevents that automobile ignition coil is broken down by high-voltage.
Background technology
Existing automobile ignition coil main parts size comprises iron core, primary coil, secondary coil, housing and the primary coil low pressure input that is connected with the outside and connects the high-voltage output end of secondary coil and respectively organize inserting terminal.During assembling, will be packed in the housing by the coil block that iron core, primary coil and secondary coil consist of, secondary coil is connected with the external high pressure output by the metal inserting terminal.
Insulating barrier adopts epoxy resin filling usually between inserting terminal and the secondary coil at present, its shortcoming is: (1) metal terminal structure often exists right angle faceted pebble and wedge angle, and behind epoxy resin cure, toughness can be short of to some extent, produces the crack in the edges and corners of metal terminal easily; (2) when ignition coil is worked, epoxy resin can interiorly can produce thermal stress, and occurrence positions deformation, and structure length is larger, and stress is healed large, can the initial ring epoxy resins peel off or the crack in right angle and the wedge angle stress concentration portion position of iron core.
The meeting that above-mentioned epoxy resin produces the crack directly endangers ignition coil, particularly or generation creepage phenomenon easy or breakdown at high-pressure work state point fire coil just.
The utility model content
The utility model is intended to provide a kind of insulating barrier that prevents to produce the crack, can improve the ignition coil insulation separation frame of ignition coil fail safe.
The purpose of this utility model can reach by following measures: a kind of ignition coil insulation separation frame, comprise the support body that engineering plastics are made, described support body takes the shape of the letter U, the two ends of support body have connecting hole, be provided with lug boss in the middle of the described support body medial surface, be provided with the high-voltage connection terminal fixed part in the middle of the described support body lateral surface.
The technique scheme difference with the prior art is: at first, provide the installation site to binding post on this separation frame, so that the installation of binding post is more firm; Secondly, insulating resin can be filled in the inboard of this separation frame, owing to an outside framework is provided for the filling of insulating resin, can prevent effectively that insulating resin from producing the crack.
Further, described engineering plastics are the PPO engineering plastics, and the PPO engineering plastics have good electrical insulating property under the condition of humidity, load, high temperature and high-fire resistance is high.
The utility model is simple in structure, and is applied widely, the crack that can prevent insulating barrier to produce, the fail safe that improves insulated coil.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the front view of the utility model ignition coil insulation separation frame embodiment;
Fig. 2 is the right view of Fig. 1.
Embodiment
Embodiment: with reference to Fig. 1, Fig. 2, a kind of ignition coil insulation separation frame, comprise the support body 1 that the PPO engineering plastics are made, described support body 1 is the U-shaped body of prolate, the two ends of support body 1 all have connecting hole 4, be provided with lug boss 3 in the middle of described support body 1 medial surface, be provided with high-voltage connection terminal fixed part 2 in the middle of described support body 1 lateral surface.
During use, first support body 1 is connected and fixed on the secondary framework by connecting hole 4 bolts, at the inner side edge filling epoxy resin of support body 1; Fixing high-voltage connection terminal on the described high-voltage connection terminal fixed part 2, high-voltage connection terminal is connected with the external high pressure output.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection range of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
