The utility model discloses an embedment mutual-inductor easy operation, it is with low costs, lead wire and coil are qualified for the next round of competitions and are difficult for opening a way.
Description
Technical Field
The utility model relates to an electric field, concretely relates to embedment mutual-inductor.
Background
In the current mutual inductor in the market, a common metal needle is used as a pin needle, a wound coil outgoing wire is wound on the metal needle for welding, in order to prevent an inner core from being broken, a section of wire thicker than the coil outgoing wire is additionally arranged on some of the mutual inductors, one end of the wire is welded with the coil outgoing wire, and then the other end of the wire is wound on the metal needle for welding, so that the welding cost is high, and the welding speed is low. Coil outgoing lines of some mutual inductors are directly led out by flexible wires, the flexible wires and the outgoing lines of the coils need to be connected and welded, the flexible wires and the outgoing lines of the coils are fixed by tin dipping welding points in an adhesive tape wrapping mode after welding, then the whole mutual inductor magnetic ring is coated with rubber, dipped with tin and insulated and protected, the process is complex, and the flexible wires are easy to be stressed and pulled and open circuits of the coil outgoing lines.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an embedment mutual inductor that easy operation, with low costs, lead wire and coil are qualified for next round of competitions and are difficult for opening a way is provided.
For solving the technical problem, the utility model provides a pair of embedment mutual-inductor, including the mutual-inductor coil, still including wrap up in the outside casing of mutual-inductor coil, the casing with the embedment has sealed glue between the mutual-inductor coil, be equipped with two lead wire jacks on the casing, the be qualified for the next round of competitions at mutual-inductor coil both ends with wear to advance after the lead-out wire is connected in the lead wire jack.
Further, the sealant is an epoxy resin sealant.
Further, the lead jack is located at the edge of the outer surface of the shell.
Furthermore, a winding post is arranged on the outer ring of the lead jack, and the mutual inductor coil is led out and wound on the winding post to be fixed.
Furthermore, outgoing lines at two ends of the transformer coil are connected with the outgoing lines in a welding mode.
The beneficial effects of the utility model are that:
1. the utility model discloses an at the outside parcel casing of mutual-inductor coil, and the casing with sealed glue of embedment between the mutual-inductor coil, sealed fixed mutual-inductor coil through the embedment, save the manual work and wrap the step of sticky tape, easy operation, reliable.
2. The utility model discloses be equipped with two lead wire jacks on the casing, the be qualified for the next round of competitions at mutual-inductor coil both ends with wear into behind the lead wire welded connection among the lead wire jack, mutual-inductor coil and lead wire are difficult to receive to drag and open a way.
3. The utility model discloses lead wire jack outer lane is equipped with the wrapping post, mutual-inductor coil both ends earlier on the wrapping post twine fixed back again with lead-out wire welded connection guarantees the fixed difficult removal in mutual-inductor coil both ends, prevents to receive because of mutual-inductor coil both ends shift and drags.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, an encapsulation mutual inductor, including mutual inductor coil 1 and lead-out wire 2, still including wrap up in the outside casing 3 of mutual inductor coil 1, casing 3 with sealed glue 4 of epoxy is sealed to the embedment between the mutual inductor coil 1, be equipped with two lead wire jacks 5 on the surface edge of casing 1, lead wire jack 5 outer lane is equipped with wrapping post 6, mutual inductor coil 1 both ends are in after winding is fixed again on wrapping post 6 with lead-out wire 2 wears into after through welded connection in the lead wire jack 5.
The utility model discloses an at 1 outside parcel casing 3 of mutual-inductor coil, and casing 3 with sealed glue of embedment between the mutual-inductor coil 1, it is fixed through sealed 4 of embedment epoxy resin mutual-inductor coil 1 saves the step that the sticky tape was wrapped up in the manual work, easy operation, reliable.
The utility model discloses be equipped with two lead wire jacks 5 on casing 3, the be qualified for the next round of competitions at 1 both ends of mutual-inductor coil with wear into behind the 2 welded connection of lead wire in the lead wire jack 5, make mutual-inductor coil 1 and lead wire 2 are difficult to receive to drag and open a way.
The utility model discloses 5 outer lanes in lead wire jack are equipped with wrapping post 6, 1 both ends of mutual-inductor coil first on 6 twine fixed back again with 2 welded connection of lead-out wire, guarantee 1 fixed difficult removal in both ends of mutual-inductor coil prevents to receive because of the displacement of 1 both ends of mutual-inductor coil and drags.
The above description is illustrative and not restrictive. Many modifications and variations of the present invention will be apparent to those skilled in the art in light of the above teachings, which will fall within the spirit and scope of the invention.
