Abstract

The invention discloses a connecting structure for a lead and a terminal. The connecting structure for the lead and the terminal comprises the lead and the terminal. The lead comprises a conductor and internal and external insulating sheath layers which wrap outside the conductor. The internal insulating sheath layer of the lead is connected with the rear pin of the terminal in a crimping way. The conductor of the lead stretches out to be connected with the front pin of the terminal in the crimping way. The problem that the diameter of the insulating sheaths of the lead exceeds the maximum crimping size of the rear pin of the terminal and direct crimping cannot be performed can be solved by the connecting structure for the lead and the terminal.

Description

A kind of wire and the attachment structure of terminal

Technical field

The present invention relates to the attachment structure of automotive wire bundle technical field, a kind of wire and terminal.

Background technology

As it is shown in figure 1, the conductor 11 at existing wire 1 Shi You center and the single layer dielectrics skin 12 being coated on outside conductor are constituted.Described wire 1 is when being connected with terminal 2 as shown in Figure 2, and the conductor 11 stretched out crimps with the front foot 22 of terminal, and insulated hull 12 periphery is crimped in the metapedes 21 of terminal.Under specified conditions, conductor insulation sheath 12 can undertake special electrical performance demands, and conductor insulation sheath 12 can be thickening, and insulated hull outside diameter d 1 crimps size range more than terminal metapedes so that existing wire directly can not crimp with terminal.As shown in Figure 3; the problems referred to above are solved at present by the way of using the patchcord 3 increasing by a section thinner; one end of this patchcord 3 is linked together by the conductor of U-shaped card 4 with described wire; junction point is protected with the protective layer such as heat-shrink tube or insulating tape 5 after connection; the other end of patchcord 3 is crimped together with terminal 2 again, and the insulated hull outside dimension of this patchcord 3 meets terminal metapedes crimping size range.

Summary of the invention

It is an object of the invention to provide the attachment structure of a kind of wire and terminal, ensureing on the premise of wire diameter size, meet it and crimp assembling with terminal.

Wire of the present invention and the attachment structure of terminal, including wire and terminal, described wire includes conductor and the inside and outside two-layer insulated hull being coated on outside conductor, and the metapedes that the primary insulation skin of described wire exposes forward with terminal crimps, and the front foot that the conductor of described wire stretches out with terminal is connected.

Preferably, separated by one layer of parting layer between described primary insulation skin and outer layer insulation skin.

Preferably, the material of described parting layer is Pulvis Talci, oils and fats, aluminium foil or plastic sheeting.

Preferably, described outer layer insulation skin is different from the color of primary insulation skin.

The present invention is by being inside and outside two-layer insulated hull by traverse design, can either ensure that the outside dimension of outer layer insulation skin meets electrical performance demands, and directly crimped with terminal metapedes by primary insulation skin, avoid using patchcord, enhance the suitability of wire and terminal, solve conductor insulation sheath diameter and exceed terminal metapedes maximum crimping size and the problem that cannot directly crimp so that wire and the simpler convenience of connection of terminal, substantially increase efficiency of assembling.

Detailed description of the invention

The present invention is further elaborated with embodiment below in conjunction with the accompanying drawings, and following example are only used for explaining the present invention, are not intended that limiting the scope of the present invention.

Being the wire 6 employed in this attachment structure as shown in Figure 4, Figure 5, it is followed successively by conductor 61, primary insulation skin 62, parting layer 63 and outer layer insulation skin 64 from inside to outside.

The purpose of described parting layer 63 is to separate inside and outside two-layer insulated hull, it is to avoid it is sticked together, and the material of parting layer can use Pulvis Talci, oils and fats, aluminium foil or plastic sheeting etc..

Primary insulation skin 62, when producing, is first coated on conductor 61 outer surface, then the material of parting layer is coated in primary insulation skin 62 outer surface, be coated on parting layer outer surface by outer layer insulation skin 64 by described wire.

Described outer layer insulation skin 64 is different from the color of primary insulation skin 62, visually produces and is clearly distinguished from, plays mistake proofing effect.

Fig. 6 show the connection diagram of above-mentioned wire and terminal 2, it is L1 ~ L2 that the metapedes 21 of this terminal crimps size range, and the outer diameter D of the primary insulation skin of this wire is between L1 and L2, for meeting wire electric property, this wire is relatively thick, and its outer layer insulation skin external diameter is more than L2.

When being linked and packed, first outer layer insulation skin 64 part of front end is cut away, exposes one section of primary insulation skin 62, then primary insulation skin portion is cutd open remove, make front end expose one section of conductor 61.

Being crimped in terminal metapedes 21 by the described primary insulation skin 62 exposed, the conductor 61 exposed front end is crimped together with terminal front foot 22, just completes the connection operation of described wire and terminal.
