Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.

Examples

The utility model provides an inner tower is inserted to eight characters tail, as shown in figure 2, including inner tower main part 1, inner tower main part 1 is provided with the through-hole that is used for placing eight characters tail female terminal 8 along the axis direction, and is provided with spacing step in the through-hole, and when eight characters tail female terminal 8 inserted the through-hole, spacing step was spacing to eight characters tail female terminal 8.

Specifically, in the present embodiment, the through holes include a first through hole 2 and a second through hole 3, and the inner diameter of the first through hole 2 is smaller than the inner diameter of the second through hole 3; the first through hole 2 is arranged at the front end of the inner frame main body 1, the second through hole 3 is arranged at the rear end of the inner frame main body 1, and the connecting part of the first through hole 2 and the second through hole 3 forms the limiting step.

There is not spacing step in traditional inner tower main part 1's the through-hole, when production, as shown in fig. 2, through coating the one deck inner membrance on the power cord that is provided with eight letter tail female terminal 8 for the inner membrance forms spacing step on eight letter tail female terminal 8, thereby makes eight letter tail female terminal 8 can not all carry out in the through-hole, and then forms creepage distance. However, in the inner film forming process, the splayed female terminal 8 is not fixed and indefinite, so after the inner film is formed, the length of the splayed female terminal 8 coated with the inner film is inconsistent, and thus, the creepage distance is inconsistent, and the use is affected.

And in this application, spacing step sets up in the through-hole in advance, and spacing step is unanimous with the distance of interior frame main part 1 front end, consequently, the inconsistent condition of creepage distance can not appear.

Further, as shown in fig. 2 and 3, in order to fix the splay-letter terminal 8, a fixing portion is further provided in the present embodiment, and the fixing portion is fixedly provided on the rear end surface of the inner frame body 1; after the splayed letter terminal 8 is inserted into the through hole from the rear end face of the inner frame main body 1, the splayed letter terminal 8 is fixed on the inner frame main body 1 by the fixing part.

Specifically, the fixing portion in this embodiment includes a bottom plate 4 and a rear cover 5, a front end of the bottom plate 4 is disposed on a rear end face of the inner frame body 1, and the bottom plate 4 and the inner frame body 1 are integrally formed; be provided with spacing groove 6 on bottom plate 4, be provided with stopper 7 with 6 matches in spacing groove on the back lid 5, after splayed female terminal 8 inserts the through-hole, stopper 7 joint in spacing groove 6, and the front end of bottom plate 4 and splayed female terminal 8's rear end butt to fix splayed female terminal 8.

In this application, when inserting splayed letter tail female terminal 8 in the through-hole of interior frame main part 1, need not to coat the inner membrance on splayed letter tail female terminal 8, reduce production technology and production time, effectual work efficiency and manufacturing cost that have promoted.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above description is only the embodiments of the present invention, and is not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
