Abstract

The present invention relates to an insulating sheath which performs the insulating protection action to a non-flux terminal and a leading wire which extends in a direction basically vertical to a terminal body. The sheath is provided with a back end sheet which is hinged with the upper wall or the lower wall of a sheath body. The free end of the back end sheet, which is not hinged, is provided with a hook with an elastic bulge; the bulge on the hook is suitable for being inserted in a hole on the wall opposite to the wall hinged with the back end sheet in the sheath, which is convenient to insert the non-flux terminal and the leading wire in the sheath or take out the non-flux terminal and the leading wire from the sheath.

Description

The insulating sleeve of non-soldered terminal

The present invention relates to be connected to by mechanical crimping the structure of the employed a kind of insulating sleeve of non-soldered terminal of circuit and each lead-in wire thereof without solder.

Fig. 1 (a) and (b) show traditional insulating sleeve 1 and be covered with non-soldered terminal 2, terminal 2 is connected with lead-in wire 3, the terminal body extension that goes between 3 and be substantially perpendicular to non-soldered terminal.As we can see from the figure; the rear end of insulating sleeve 1 is made up of sheet 11 and sheet 12; protecting go between 3 and go between 3 and non-soldered terminal 2 between connector 4; described up and down sheet is articulated with the relative wall that is covered with terminal front end and near sheath body thereof, and sheet 11 and 12 tail are bent to form the aft bulkhead of sheath when partly closing.Opening articulated sheet 11 and 12 just can insert non-soldered terminal 2 and lead-in wire 3 in the sheath.After non-soldered terminal 2 and lead-in wire 3 insertions were in place, the projection 17 that forms on the crooked free end with sheet is embedded in the hole of offering on another chip bonding end 18 just can close sheath.

Yet traditional insulating sleeve has two openable 11 and 12 as mentioned above, thereby its manufacture method is all quite complicated with its use.

In addition, when sheet closed up and down, its free bend end separately must flush basically each other.Meet this requirement, projection 17 and hole 18 must go out from each free distal process of sheet up and down, as shown in Fig. 1 (b), thereby make once more its make and use further complicated.

The objective of the invention is to eliminate the above-mentioned shortcoming of traditional sheath, way provides and a kind ofly not only is easy to open and closes but also be convenient to novel insulating sleeve with the terminal removal in case of necessity.

For achieving the above object; the sort of insulating sleeve of protecting non-soldered terminal and being substantially perpendicular to the lead-in wire of terminal body of the present invention has the wall of a unbending sheath sheet and jacket body articulated; when closing, sheath forms the aft bulkhead of sheath; on the non-hinged free end of sheath sheet, be provided with a hook; the free end of hook has an elastic bumps, and is suitable from the inboard hole that embeds on the jacket body oppose side wall of jacket body.

Fig. 1 (a) and 1 (b) show the plane graph and the cross-sectional side elevation view of traditional insulating sleeve respectively, and wherein, lead-in wire and non-soldered terminal are partly inserted in the sheath.

Fig. 2 shows the cross-sectional side elevation view of insulating sleeve of the present invention, Fig. 2 (a) shows lead-in wire and non-soldered terminal is partly inserted situation in the sheath, Fig. 2 (b) shows lead-in wire and non-soldered terminal is inserted the interior situation of sheath fully, and Fig. 3 (c) then shows with pin by the projection on the pressure hook to unload the situation of non-soldered terminal.

Fig. 3 is the cross-sectional side elevation view of most preferred embodiment of the present invention.

Fig. 4 is the cross-sectional side elevation view of another most preferred embodiment of the present invention.

Fig. 5 and Fig. 6 are the plane graphs of sheath shape of the present invention.

The end view of Fig. 2 (a) is represented a non-soldered terminal 2, its terminal body 21 is at tie point place that inserts sheath 1 and lead-in wire 3 quadratures, find out obviously that from this figure the back dististyle 13 of sheath 1 hingedly is connected on the wall 15 of sheath and is opening so that non-soldered terminal that is connected thereto 2 and lead-in wire 3 insert.

After terminal 2 and lead-in wire 3 insert and finish, back dististyle 13 is fixed to the wall 14 of sheath from the hole 18 of the inner embedding of shovel wall 14 by the projection 17 that will be located at the hook 16 on the dististyle 13 of back, as shown in Fig. 2 (b), in the insulating sleeve 1 of so just non-soldered terminal 2 and lead-in wire 3 being packed into securely.

In the time of non-soldered terminal 2 need being taken out from insulating sleeve 1 with lead-in wire 3, can push projection 17 (as shown in Fig. 2 (C)) with pin 5, thereby back dististyle 13 is discharged from wall 14.The back dististyle 13 of insulating sleeve 2 is made by elastoplast, thereby takes out in the patchhole 18 of being not difficult or from hole 18.

Before entering hole 18, projection 17 contacts with the inner surface of wall 14, as shown in Fig. 2 (b) to front slide.Therefore projection 17 preferably should make its shape form guarantee its can be on the inner surface of wall 14 smooth sliding, and successfully in the embedded hole 18.

Fig. 3 shows the shape projection 17 triangular in shape basically of cross section, and Fig. 4 shows the projection 17 that the shape of cross section is combined by different arcs.

Sheath 1 with back dististyle 13 of hook 16 and projection 17 can be made different shape.Fig. 5 shows a kind of L font sheath, and its part 21 is covered with lead-in wire 3 and joint thereof, and its another part 22 is covered with the tip side 23 of non-soldered terminal 2, and these two parts are orthogonal in plan view.Fig. 6 shows another kind of sheath, and the plane graph of this sheath is rectangular basically.

Usually, be equipped with the hole 18 of one or two projection 17 and respective number, but this number is not limited specifically.

Though the combination of a projection 17 and hole 18 formation is simple, and only pushes a projection 17 and just can decontrol back dististyle 13 as shown in Fig. 2 (C), the combination that two or more projectioies 17 and hole 18 form can guarantee more firm joint.

In insulating sleeve of the present invention, as implied above go out like that, have only back dististyle 13, rather than in traditional as described above sheath two opposed external members arranged like that, with respect to the upper wall or the lower wall opening and closing of sheath.In addition, the not only easy embedded hole 18 of the small embossment 17 on the hook 16, and operation smoothly is provided.

As Fig. 2 (a), 2 (b), 2 (c), back dististyle 13 are not difficult to make it to engage with wall 14, and the concrete practice is that hook 16 is contacted with the inner surface of wall 14, and the projection 17 on the hook 16 is embedded in the hole 18 of wall 14.Need be when from insulating sleeve, taking out with lead-in wire 3 and non-soldered terminal, as long as can be easily back dististyle 13 be opened by the projection on the pressure hook 16 17 with pin 5.

Though simplicity of design, insulating sleeve of the present invention are more superior than traditional sheath in many aspects.
