In existing lamp decoration industry, the employed transformer of low-voltage electrical apparatus, the one side is equipped with the fastening structure of electric wire, in order to securing electric lines.And traditional fastening structure lock onto the line ball lid on the transformer case with screw usually, and electric wire is sandwiched between line ball lid and the transformer case, thereby electric wire is fixedly clamped.Yet no matter this kind is to install or dismounting in the mode of screw locking, all need by instrument, so trouble is used in the common reflection of consumer.
The utility model content
The purpose of this utility model is to provide a kind of fastening structure of transformer electric wire, and it does not need tool using conveniently electric wire to be fixedly clamped.
For achieving the above object, technical solution of the present utility model is:
A kind of fastening structure of transformer electric wire, but the groove of securing electric lines be provided with in a side of transformer case, and groove is provided with the line ball lid that electric wire can be clamped, and covers at groove and line ball and is respectively equipped with the clamping structure that cooperatively interacts.
Described clamping structure is some pawl shape draw-in grooves of being located at recess sidewall, with some pawl shape grabs of being located at line ball lid side.
Described clamping structure is then established an arc convex for be provided with some arc-shaped recess on the sidewall of groove in line ball lid side.
The front end place of described groove is provided with the latch that is higher than groove floor; And be provided with and the corresponding front-seat latch of groove latch at the front end place of described line ball lid, be provided with more corresponding with the bottom surface of groove than its low back row's latch in this latch rear end, front row.
Described groove two sides are provided with orientable gear, match with the groove gear and also be provided with gear in described line ball lid both sides.
Be formed with the slit between line ball lid behind the described fastening and the groove.
After adopting such scheme,, therefore need not use any instrument because the utility model adopts the mode that fixes to reach the purpose of fastening electric wire, can reach be easy to install, effect for convenience detach.In addition, described clamping structure can be several draw-in groove that cooperatively interacts and grabs, or arc convex and arc-shaped recess, therefore applicable to the electric wire of different size, makes suitability of the present utility model stronger.Moreover, the utility model has designed the latch that is higher than groove floor at groove front end place, has also designed the forward and backward row's latch with high low head at line ball lid front end, and it cooperatively interacts and electric wire can be pressed into " Z " shape, thereby reach the purpose of fastening electric wire, the method safety, easy, effective.

Embodiment
As shown in Figure 1, a side of transformer case 1 described in the utility model is provided with a groove 11, is provided with two binding posts 12 in this groove 11, and external cable 2 can be received on this binding post 12; On groove 11, be provided with line ball lid 3, in order to electric wire 2 clampings; More than same as the prior art, characteristics of the present utility model are:
Be respectively equipped with the clamping structure that cooperatively interacts on described groove 11 and line ball lid 3, this clamping structure can be some pawl shape draw-in grooves 13 of being located at groove 11 sidewalls, and is located at some pawl shape grabs 31 that line ball covers 3 sides.
In addition, be provided with the latch 15 that is higher than groove 11 bottom surfaces 14, be provided with orientable gear 16 in groove 11 two sides at the front end place of described groove 11; Front end place at described line ball lid 3 is provided with and groove 11 latches 15 corresponding front-seat latches 32, be provided with more correspondingly with the bottom surface 14 of groove 11 in these front row latch 32 rear ends, cover 3 both sides at line ball and also be provided with the gear 34 that matches with groove 11 side gears 16 than its low back row's latch 33.
The utility model is when assembling, as shown in Figure 2, line ball lid 3 is embedded in the groove 11 of transformer case 1, line ball cover the grab 31 of 3 both sides will be automatically with groove 11 on corresponding draw-in groove 13 engage mutually preventing that line ball lid 3 from moving up and down, and the engaging back since the gear 16 of groove 11 and line ball cover 3 gear 34 and cooperate and make line ball cover 3 can't to move forward and backward; And then utilize the latch 15 at groove 11 front end places and the high low head between its bottom surface 14, the end row latch 32 and back row's latch 33 that cooperate line ball lid 3, electric wire 2 is pressed into " Z " shape (shown in Fig. 3,4), thereby reaches the purpose of fastening electric wire 2, the method safety, easy, effective.
In addition, in view of the employed external power cord specification of present consumer disunity, it is the thickness difference of electric wire, the utility model is designed to several grooves with the grab 31 of described line ball lid 3 and the draw-in groove 13 of described groove 11, thereby any electric wire all can be adaptive, as long as the consumer is after being fixed on binding post 12 with electric wire 2, and line ball lid 3 being pressed onto the position that is fit to this electric wire 2 can be with electric wire 2 clamping again, and described groove also can suitably increase or reduce as required.
When desire dismounting line ball covers 3, only need firmly groove 11 two sides outwards to be broken into two with one's hands, grab 31 and draw-in groove 13 are broken away from, line ball can be covered 3 and take out.And for convenience groove 11 two sides are outwards broken into two with one's hands, between lid 3 of the line ball behind the fastening and groove 11, can form a slit 4, this slit 4 can be formed by the breach that is arranged on groove 11 two sides, like this, only need to stretch in this slit 4, can conveniently exert oneself with finger, and then conveniently the two side of groove 11 is broken into two with one's hands, perhaps embed the breach of groove 11, can conveniently line ball lid 3 be levered up, to carry out wiring work with straight screwdriver.
Moreover described clamping structure also can promptly be provided with some arc-shaped recess 111 as shown in Figure 5 on the sidewall of groove 11, cover 3 sides at line ball and then establish an arc convex 35.When assembling, according to the thickness of electric wire, described arc convex 35 is fastened in the corresponding arc-shaped recess 111, thereby electric wire is clamped.
In addition, described clamping structure is not limited to above-mentioned two kinds, as long as can make line ball lid and groove fix in the mode that fixes, and all should be in protection range of the present utility model.Moreover in the described clamping structure, the position of grab and draw-in groove, camber projection and arc-shaped recess is provided with all interchangeable, and promptly grab and arc convex are located in the groove, and draw-in groove and arc-shaped recess then are located in the groove.
