Abstract

The utility model discloses a 2M cable head belongs to the connection fittings field of cable or electric wire for solve the problem that current 2M cable head is of low quality, service life is short. 2M cable head, the cable head is from interior to being interior conducting layer, the inner insulating layer, shielding layer, outer jacket, crimping layer outward in proper order, interior conducting layer is formed by the contact pin welding of cable tip inner conductor with the 2M connector, the roller flower cylinder that is the 2M connector between the inner insulating layer and the shielding layer, the shielding layer evenly wraps up roller flower cylinder, the crimping layer covers and is crimp connection between shielding layer and crimping layer tip and the shielding layer, cup joint in the 2M cable head outside on the pyrocondensation layer. The cable head conduction can be good, life can reach more than the decade.

Description

A kind of 2M cable end

Technical field

The utility model belongs to the connection fittings field of cable or electric wire, specifically, relates to a kind of manufacture craft of 2M cable end.

Background technology

2M cable end small volume, manufacture craft requires strict; Often easily cause the phenomenons such as cable end heart yearn rosin joint, sealing-off, broken string in operation, cause operating channel interrupt, telecommunication circuit fault, and heart yearn loose contact sometimes in checking process, sometimes can recover again normal, cause phenomenon of breaking during communication line fashion, it has endless trouble.Therefore the quality of 2M cable end directly concerns communication security and communication quality.

Utility model content

For solving the problem, the utility model provides the 2M cable end of a kind of good communication quality, long service life.

2M cable end described in the utility model, described cable end is followed successively by inner conducting layer, inner insulating layer, screen, outer jacket, crimping layer from the inside to the outside, described inner conducting layer is welded by the contact pin of cable end inner wire and 2M connector, it is the roller flower cylinder of 2M connector between described inner insulating layer and screen, described screen evenly wraps up roller flower cylinder, described crimping layer covers screen and crimping layer end is connected for crimping with between screen, and described shrink wrap layer is socketed in outside 2M cable end.

2M cable end described in the utility model, inner conducting layer is welded by the contact pin of cable end inner wire and 2M connector, preferred employing fusing point is that 125 DEG C and above scolding tin are welded, connect at screen external application crimping lamination, be socketed in the outside shrink wrap layer of cable end, whole cable end has triple protection, can ensure that the contact pin in cable inner conductor and 2M connector is combined closely, can not come off, adopt the power of about 60N to pull cable end and do not occur loosening sign, described cable end can ensure communication quality, and useful life is extended.

2M connector described in the utility model, belongs to the one of SMB connector, is also called 2M head.

Preferably, described crimping layer is metal material, be preferably aluminum alloy material, described crimping layer is the cannula-like structure of both ends open, the two ends of crimping layer and screen are crimped together by Crimping Pliers by crimping layer, certainly for improving the firmness of cable end, Press Plier can be utilized all to be crimped on the shielding layer by crimping layer.

Preferably, described shrink wrap layer is thermal contractible plastic, and described shrink wrap layer is the cannula-like structure of both ends open.

Preferably, described screen is the network structure of single line braiding, and when crimping layer crimps with screen, ensure that screen is all inner at crimping layer, cut if any exposed screen, object improves communication quality, prevents signal disturbing.

Preferably, be better attached cable head, improve its firmness, the inner conducting layer of described cable end, inner insulating layer and outer jacket are from the inside to the outside successively in step-like arrangement, and inner conducting layer length is the longest.

Compared with prior art, the beneficial effects of the utility model are: cable end inner conducting layer described in the utility model is welded by the contact pin of cable end conductor and 2M connector, and conduction property is good; Cable end also comprises crimping layer and shrink wrap layer, and to cable end with protection, can ensure that cable end is relatively more firm, when pulling by the power of about 60N, cable end non-loosening phenomenon occurs; The life cycle of whole cable end is long, and useful life can reach more than 10 years.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Wherein, 1-inner wire; 2-inner insulating layer; 3-screen; 4-outer jacket; 5-crimps layer; 6-shrink wrap layer; 7-contact pin; 8-roller flower cylinder.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further explained.

A kind of 2M cable end, comprise the inner conducting layer, inner insulating layer 2, screen 3, outer jacket 4, the crimping layer 5 that set gradually from the inside to the outside, the inner conducting layer of described cable end, inner insulating layer 2 and outer jacket 4 successively in step-like arrangement, from inside to outside shorten from the inside to the outside gradually.Inner conducting layer is welded by the contact pin 7 of cable end inner wire 1 with 2M connector, it is the roller flower cylinder 8 of 2M connector between described inner insulating layer 2 and screen 3, described screen 3 is parcel roller flower cylinder 8 evenly, described crimping layer 5 is the aluminium alloy sleeve pipe of both ends open, crimping layer 5 covers screen 3 and crimping layer 5 end is connected for crimping with between screen 3, described shrink wrap layer 6 is the cannula-like structure of both ends open, and shrink wrap layer 6 is socketed in outside 2M cable end.

Its manufacture method is:

Now crimping layer 5 and shrink wrap layer 6 are sleeved on one end of cable, then the inner wire 1 of cable end is stripped out, the inner wire 1 be stripped out is inserted in the contact pin 7 of 2M connector, the roller of 2M connector flower cylinder 8 is plugged between the inner insulating layer 2 of cable and screen 3, screen 3 is made evenly to be attached on the roller flower cylinder 8 of connector, crimping layer 5 is covered on screen 3, then compress with the two ends of Crimping Pliers at crimping layer 5, then the contact pin 7 of inner wire 1 and 2M connector is welded, after shrink wrap layer 6 is sleeved on outside cable end, heat gun is utilized to make shrink wrap layer 6 and cable end close contact.
