Embodiment
Explain with reference to the accompanying drawings embodiment of the present utility model.
Fig. 1 to Fig. 8 represents the embodiment 1 of insulating cover for terminal of the present utility model, and Fig. 1 means the stereogram of the state of having opened obvolvent portion, and Fig. 2 means the front view of the state of having opened obvolvent portion.
In above-mentioned figure, Reference numeral 1 is cylindrical portion, and Reference numeral 2,3 is obvolvent portion, and as shown in Figure 2, the terminal of the present utility model packing into before the terminal being connected with electric wire forms T word shape with insulating cover by cylindrical portion 1 and obvolvent portion 2,3.
Thereby, while making fitting projection 4 and chimeric recess 5 chimeric closing obvolvent portion 2,3, the surface that is quadrangle shape due to fitting portion cross section each other contacts and fixes, therefore obvolvent portion 2,3 can not rock, in addition, because the contact-making surface of hook part 4a and protuberance 5a is wider tabular surface, thereby so fitting portion fixed reliably obvolvent portion can not opened easily.
As shown in Figure 7, the terminal of this embodiment 1 is the structure that the female terminal 20 being connected with electric wire 21 is packed into inside and fixes at the male terminal 10 of the interior insertion inserted sheet of female terminal 20 type with insulating cover, as shown in Figure 6, the contrary side in male terminal 10Yu Qi inserting side of this inserted sheet type is formed with shoulder 10a.
Therefore, being inserted into, this male terminal 10 is enclosed in terminal when interior with the female terminal 20 in insulating cover, when cylindrical portion 1 is the identical A/F of width with male terminal 10 inserting side, the shoulder 10a of male terminal 10 encounters the edge of cylindrical portion 1, thereby cannot be inserted into fully in the female terminal 20 in cylindrical portion 1.
Therefore, by the edge in cylindrical portion 1, form the breach 1a corresponding with the shoulder 10a of male terminal 10, can male terminal 10 is chimeric fully with the female terminal 20 in cylindrical portion 1.
As represented, to terminal of the present utility model, with insulating cover embodiment 1, inserted as shown in Fig. 8 of state of male terminal, in the situation that there is the male terminal 10 of shoulder 10a to the interior insertion of cylindrical portion 1 that has packed female terminal 20 into, by the edge in cylindrical portion 1, be provided with breach 1a, can make male terminal 10 fully chimeric with the female terminal 20 in cylindrical portion 1.Thus, can suppress terminal after chimeric rocking each other, can prevent from waiting by vibration the comes out of engagement causing.
In addition, as shown in Figure 1 and Figure 2, the terminal of this embodiment 1 is provided with rib 1b with insulating cover on cylindrical portion top, also in an obvolvent portion 3, is provided with the rib 3a extending upward than composition surface 3b.Thus, as shown in Figure 3, closing and the gap of 2,3 o'clock ，Bu Huizi bonding parts of engaging obvolvent portion is exposed inner electric wire etc. and become the structure that insulating properties is higher.
Fig. 9 to Figure 13 represents the embodiment 2 of insulating cover for terminal of the present utility model.
The terminal of this embodiment 2 is used in the female terminal 22 of the flag form shown in Figure 12 with insulating cover, consist of in the same manner with embodiment 1 cylindrical portion 11 and obvolvent portion 12,13, in an obvolvent portion 12, has fitting projection 14, in another obvolvent portion 13, has chimeric recess 15.
In use, to cylindrical portion 11, pack the head of female terminal 22 into, by closing obvolvent portion 12,13, cover remainder and the electric wire 21 of female terminal 22.Figure 11 represents that the obvolvent portion that closes of embodiment 2 makes fitting projection 14 be embedded in chimeric recess 15 and state after engaging.
This embodiment 2 is identical with embodiment 1, for closing and fitting projection 14, the chimeric recess 15 of engaging obvolvent portion 12,13 is all configured to cross section and is quadrangle, after closing obvolvent portion 12,13 and making 12,13 engagings of obvolvent portion, can fix reliably and can not open easily.
In addition, at cylindrical portion 11 edge, be provided with breach 11a, when male terminal 10 insertions have been encased in to the female terminal 22 in cylindrical portion 11, the shoulder 10a of male terminal 10 can not encounter cylindrical portion 11 and can be inserted into fully female terminal 22 inside, can suppress terminal after chimeric rocking each other, can prevent from waiting by vibration the comes out of engagement causing.
And, because the top edge in cylindrical portion 11 is provided with rib 11b, all inside sidewalls of an obvolvent portion 13 in obvolvent portion are provided with rib 13a, therefore after having closed obvolvent portion, can utilize above-mentioned rib 11b, 13a to prevent that the gap at inner electric wire Deng Cong junction surface from exposing, better aspect insulating properties.
