Abstract

The utility model relates to an auto-winding winder comprising an insulating circular shell. A circular spring is coaxially mounted in the shell and comprises a telescopic end and a tension end. The telescopic end is fixed in the middle of the shell. The middle and edge of one side of the shell are provided with wire outlets respectively. A test wire is mounted at the tension end of the circular spring. The tension end is located between the connecting ends of the test wire, one end of the test wire extends out of the wire outlet in the middle of the shell, and the other end of the test wire extends out of the wire outlet formed in the outer edge of the shell. Two connecting ends of the test wire are provided with insulating protective sleeves respectively. The auto-winding winder has the advantages that the test wire is kept insulated with respect to the circular spring, so that the function of testing loop connection is ensured; the test wire can be linearly connected as far as possible by the aid of the circular spring, so that tangling of the test wire is avoided and a test loop is vivid and is easy for examination; the test wire can telescope automatically, so that the time of sorting the test wire is shortened greatly; the test wire of proper length can be wound as required, so that intermediate connectors for the test wire are reduced.

Description

Automatic recovery type winder

Technical field

The utility model belongs to dynamo-electric check implement accessory equipment field, especially a kind of automatic recovery type winder.

Background technology

In the high-potting process, often appearance connects the situation of tens test wires simultaneously since every test wire is different in size and the loop is more, test wire is chaotic easily, cause the loop connection state to be difficult for checking, and after test is finished, big, the consuming time length of arrangement test wire difficulty.Simultaneously, because every test wire limited length, when many test wire serial connections, all there are risk in splice insulation and connective stability.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of simple in structure, automatic recovery type winder of being easy to put in order is provided.

The technical solution adopted in the utility model is:

A kind of automatic recovery type winder; comprise an insulation circular shell; coaxial installation one coil spring in this housing; this coil spring comprises serrated end and the end that stretches; its serrated end is packed in the housing middle part; middle part and edge at housing one side are shaped on a wire hole respectively; at coil spring stretching end a test wire is installed; the end that stretches connects between the line end at test wire; one end of this test wire stretches out the wire hole that the outer middle part of housing is shaped on; the other end stretches out the wire hole that the housing outward flange is shaped on, and two test wire coupling ends all are shaped on insulation protective jacket.

And, on the outside position around described each wire hole, all by insulated wire one locating dowel pin is installed, each locating dowel pin and the corresponding and extruding cooperation one by one of its wire hole on every side.

And, hold with the test wire coupling end distance of stretching out the wire hole that the middle part is shaped on outside the housing greater than coil spring limit of stretch radius in described coil spring stretching.

Advantage of the present utility model and good effect are:

1, test wire and coil spring keep insulation in the utility model, guarantee the function that the test loop connects; Utilize coil spring to make the test wire straight line of can trying one's best connect, avoided the winding of test wire, make clear being easy in test loop check, after test finishes, test wire can be withdrawn automatically, the arrangement test wire time that significantly reduces, also the test wire that can reel and to be of convenient length according to need reduces the test wire center coupling.

2, the wire hole of an end of test wire by the housing center derived in the utility model, is conducive to reduce the collapsing length of test wire fixed end test wire when flexible; And the other end can be shunk in the drive withdrawal housing by coil spring, takes full advantage of the guide function of coil spring, guarantees that test wire is flexibly flexible, avoids bite.

3, the insulation protective jacket external diameter is bigger in the utility model, and the test wire coupling end can not return in the housing, pushes two wire holes respectively by locating dowel pin, and the wire hole shutoff is located test wire thus, and the test wire coupling end can not return in the housing.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.

A kind of automatic recovery type winder, comprise a cylindrical insulation shell 1, coaxial installation one coil spring 10 in this housing, this coil spring comprises serrated end 12 and the end 11 that stretches, the coil spring serrated end is packed in the housing middle part, middle part and edge at housing one side are shaped on a wire hole 2 and 4 respectively, all by insulated wire 8 locating dowel pin 3 and 7 are installed on the outside position around each wire hole, each locating dowel pin and the corresponding and extruding cooperation one by one of its wire hole on every side.

At coil spring stretching end a test wire is installed; coil spring stretches end between test wire two coupling ends; one coupling end 9 of this test wire stretches out the wire hole that the outer middle part of housing is shaped on; another coupling end 5 stretches out the wire hole that the housing outward flange is shaped on; two test wire coupling ends all are shaped on insulation protective jacket 6, and each insulation protective jacket external diameter is all greater than each wire hole aperture.

Coil spring stretches end and the test wire coupling end distance of stretching out the wire hole that the outer middle part of housing is shaped on greater than coil spring limit of stretch radius, namely coil spring stretch end with the test wire coupling end distance of stretching out the wire hole that the outer middle part of housing is shaped on coil spring serrated end and the distance between holding of stretching during greater than the coil spring limit of stretch.

Using method of the present utility model is:

Test wire two coupling ends stretch out respectively outside the housing and are connected with Devices to test, to form the loop, push two wire holes respectively by locating dowel pin, and the wire hole shutoff is located test wire thus, avoid coil spring that test wire is shunk thus and take back; After test, unclamp locating dowel pin, test wire then can be shunk to drive by coil spring returns housing, because the insulation protective jacket external diameter is bigger, the test wire coupling end can not return in the housing.

Because stretching, holds with the test wire coupling end distance of stretching out the wire hole that the middle part is shaped on outside the housing greater than coil spring limit of stretch radius coil spring, even so the test wire coupling end that stretches out the wire hole that the middle part is shaped on outside the housing when coil spring is stretched to the limit, also can not be shunk by coil spring and take back.
