Abstract

The utility model provides a coil wire winding structure, includes coil skeleton and four pins of drawing forth from coil skeleton, its characterized in that: respectively there is one enameled wire wire winding structure on every pin, enameled wire wire winding structure is forming the close three rings of structures of winding on every pin upper portion, and the continuity is drawn midfoot at every and is formed rare two rings of structures of winding, and the continuity is close around two rings of structures in every pin bottom formation again, the utility model discloses foretell technical scheme has been taked, following beneficial effect can be realized: take wire jumper design when 1. Twining the pin, realize in the length space of pin that pin upper portion is close around three rings, then rarely wind two rings, it is close around two rings in the bottom again, wind two rings of capillary effects to scaling powder and soldering tin and disturb through the centre is rare, finally realize tin in three rings~four rings alls on the upper portion, tin is not gone up for one~three ring in the bottom, is guaranteeing to stablize under electrical connection's the prerequisite like this, and the bottom keeps the flexibility of enameled wire, avoids splitting under extreme condition.

Description

A kind of coil-winding structure

Technical field

This utility model relates to coil-winding structure, belongs to electronic technology field.

Background technology

Bar code scan instrument ultraprecise series micro-coil, this bar code scan instrument can use in the presence of a harsh environment, for coil requirement can anti-vibration, anti-drop, reliable and stable; Common coiling and scolding tin mode cannot meet vibrations and anti-drop requirement, in this little coil production process, there are the following problems: 1. in the coiling stage, because enamel-covered wire is too thin, start line and buttock line easily breaks; 2. in the scolding tin stage, often due to capillarity causes scolding tin size not meet drawing requirement.

In view of this, the present inventor studies and devises a kind of coil-winding structure, and this case thus produces.

Utility model content

The purpose of this utility model is in that to provide a kind of coil-winding structure, is arranged by the coiling of pin, it is possible to solve the technical problem in above-mentioned background, and the technical scheme in the invention for solving the technical problem is:

A kind of coil-winding structure, including coil rack and from four pins drawn coil rack, it is characterized in that: each pin is respectively arranged with one group of enamel-covered wire winding structure, described enamel-covered wire winding structure is close around three coil structures for being formed on each pin top, continuity formed in the middle part of each pin rare around two coil structures, then continue formed bottom each pin close around two coil structures.

As the optimal way of embodiment, described enamel-covered wire winding structure is formed by three enamel-covered wires are stranded.

This utility model takes above-mentioned technical scheme, following beneficial effect can be realized: when being 1. wound around pin, take wire jumper to design, the existing pin top of the length space interior-excess of pin is close to be enclosed around three, then rare around Liang Quan, close around Liang Quan in bottom again, the capillary effect of scaling powder and scolding tin is disturbed around two circles by centre is rare, finally realize top three and enclose ~ tetra-circles all upper stannum, stannum is not enclosed in bottom one ~ tri-, so under the premise ensureing stable electrical connection, bottom keeps the flexibility of enamel-covered wire, it is to avoid rupture under severe conditions; 2. enamel-covered wire coiling forms by three enamel-covered wires are stranded, allows enamel-covered wire coiling when being wound around pin from one and become three bursts of strands together, allows strength enhancing 10 times.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

As shown in Figure 1, this utility model discloses a kind of coil-winding structure, including coil rack 1 and from four pins drawn coil rack, each pin is respectively arranged with one group of enamel-covered wire winding structure 3, described enamel-covered wire winding structure 3 is close around three coil structures for being formed on each pin top, continuity formed in the middle part of each pin rare around two coil structures, then continue formed bottom each pin close around two coil structures.

As the optimal way of embodiment, described enamel-covered wire winding structure 3 is formed by three enamel-covered wires are stranded.

In the present embodiment, four pins are from left to right followed successively by the first pin the 21, second pin the 22, the 3rd pin 23 and the 4th pin 24, one enamel-covered wire forms winding structure 3 from the first pin 21 coiling, then around entering coil rack 1, after coil rack 1 coiling completes, it is coiled into winding structure 3 around entering the 3rd pin 23, another strand of enamel-covered wire forms winding structure 3 around from the second pin 22 coiling, then around entering coil rack 1, it is coiled into winding structure 3 around entering the 4th pin 24 after coil rack 1 coiling completes, starting and finishing up of two strands of enamel-covered wires is coiled into one group of close rare close formula enamel-covered wire winding structure respectively on four pins, by full-automatic accurate coiling plus full-automatic twisted wire, full-automatic stranding process is used in each pin coiling place, enamel-covered wire coiling forms by three enamel-covered wires are stranded at each pin portions, be wound around pin time from one and become three bursts strand together, allow strength enhancing 10 times, wire jumper is taked to design during full-automatic winding pin, the existing pin top of space interior-excess at pin 2.3mm is close around three circles, then rare around Liang Quan, close around Liang Quan in bottom again, around two circles, the capillary effect of scaling powder and scolding tin is disturbed by centre is rare, finally realize top three and enclose ~ tetra-circles all upper stannum, stannum is not enclosed in bottom one ~ tri-, so under the premise ensureing stable electrical connection, bottom keeps the flexibility of enamel-covered wire, it is to avoid rupture under severe conditions.

The above, it is only this utility model preferred embodiment, therefore the scope that this utility model is implemented can not be limited according to this, the equivalence namely made according to this utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that this utility model is contained.

Claims (2)
