Description

Cable connector

The utility model relates to a kind of cable connector, particularly relates to a kind of lead of its cable and the pad between conducting terminal and can avoid because of frequent plug cause the getting loose cable connector with preferable stretching resistance of phenomenon.

The function of electronic installation constantly increases now, and its volume constantly reduces relatively, makes that the layout of electric connector is more and more tightr, and therefore, docking with it and the shape of the cable connector of telecommunication transmission is provided is towards lightening development; Simultaneously, it is simple and efficient, really firm that the compound mode of this cable connector is also made every effort to, and uses the raising assembling efficiency.

But, with regard to present cable connector, its existing shortcoming, integration arrangement can be as described below substantially:

(1) lead of cable and connector terminals come off easily: because the lead of cable and connector terminals are when welding, lid is very tiny so that be difficult for welding because of the both, add that cable connector must have the action of inserting or extracting on reality is used, therefore, failing effectively to prevent under the directly stressed situation of terminal, its lead and terminal then are easy to come off, and then cause and can't use.

(2) phenomenon that easily gets loose after the shell combination of cable connector: because connector shell generally is with the combination of engaging mode, however because of not good snap-on design, and after using a period of time, promptly can produce the phenomenon that gets loose gradually, be to cause the bad of product.

(3) cable connector is aspect the encapsulating operation; it thrusts cable and the glue that produce to overflow easily: since the lead of cable and terminal weld finish after; must it be coated with an insulating material; preventing short circuit, and generally be to carry out in the encapsulating mode, yet; the strength of encapsulating is very big; thereby regular meeting thrusts the lead of this cable, therefore, also only can scrap and can't make again or maintenance in case damage to some extent.

(4) as shown in Figure 1, the insulation shell 10a of general cable connector 1a is comparatively spacious, yet, emphasizing that volume is little and transmission speed is now fast, promptly can't satisfy user's demand.

The purpose of this utility model.Be to provide a kind of cable connector, it mainly convexes with an extension block in the welding ends of insulation shell, and after implementing covered type moldings formed therefrom (over mold), this extension block can supply the interlock of the cladding of moldings formed therefrom, insulation shell and cladding can not come off because of the plug on using, reach the effect of firm combination according to this.

In order to reach above-mentioned purpose, the utility model provides a kind of cable connector, it is characterized in that, comprising: a cable, and it is arranged with a plurality of leads; An and insulation shell, its two ends are respectively equipped with a butt end and a welding ends, be penetrated with a plurality of terminal storage tanks therebetween, these terminal storage tanks are plugged with corresponding conducting terminal respectively, these conducting terminals stretch out this welding ends, welding with these leads, and this welding ends convexes with one and extends and determine.Described extension block, it has preferable stretching resistance behind the covered type moldings formed therefrom.

In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended accompanying drawing only provide with reference to and explanation usefulness, be not to be used for to the utility model limitr in addition.

Fig. 1 is the outside drawing of known cable connector;

Fig. 2 is the three-dimensional exploded view of the utility model cable connector first embodiment;

Fig. 3 is the three-dimensional combination figure of the utility model cable connector first embodiment;

Fig. 4 is the three-dimensional exploded view of the utility model connector second embodiment;

Fig. 5 is the three-dimensional combination figure of the utility model cable connector second embodiment.

Seeing also Fig. 2 and shown in Figure 3, is three-dimensional exploded view and the three-dimensional combination figure of the utility model first embodiment, and cable connector provided by the utility model includes members such as a cable 1 and an insulation shell 2, wherein:

This cable 1 is arranged with a plurality of leads 10 and is positioned this insulation shell 2 for linking, and these insulation shell 2 one ends are butt ends 21, this butt end 21 is for being plugged in a butt connector (not shown), the other end with respect to this butt end 21 then is a welding ends 22, and this welding ends 22 is to connect this cable 1 to use for the transmission of telecommunication; Moreover, be penetrated with a plurality of terminal storage tanks 23 between this butt end 21 and this welding ends 22, be plugged with a plurality of corresponding conducting terminals 24 in these terminal storage tanks 23 respectively, these conducting terminals 24 stretch out this welding ends 22, and weld with the lead 10 of this cable 1.

Again, welding ends 22 bottom vertical of this insulation shell 2 are extended with an extension block 25, and these extension block 25 surfaces are provided with a plurality of grooves 26, these grooves 26 can provide more contact area, in this way, after lead 10 welding of the conducting terminal 24 of this insulation shell 2 and this cable 1, implemented covered type moldings formed therefrom (over mold) and be formed with a cladding 3, this cladding 3 can fill up the groove 26 of this extension block, use the interlock strength of 3 of this insulation shell 2 of increase and this claddings, so that can avoid this cladding 3 because of the excessive phenomenon that gets loose that causes of plug strength, in brief, when this cable 1 was subjected to pulling force, this pulling force can reach this cladding 3, and this cladding 3 can be caught this extension block 25, can not have influence on the effect of the pad of this lead 10 and conducting terminal 24 such as grade.

In addition, these conducting terminals 24 are that the suitable distance of stretching out this welding ends 22 vertically bends, and be parallel to this extension block 25 upper ends, in addition, welding ends 22 horizontal-extendings one fin 27 in this insulation shell 2, this fin 27 is the usefulness of contact when supplying these leads 10 with these conducting terminals 24 welding, to prevent that these conducting terminals 24 are because of unsettled its compressive deformation that caused.

Other sees also Fig. 4 and shown in Figure 5, be three-dimensional exploded view and the three-dimensional combination figure of the utility model second embodiment, cable connector provided by the utility model includes a cable 1 and a current supply cable 1 is connected the members such as connector 2 of locating, wherein with the aforementioned first embodiment difference, be to be that this extension block 25 is the welding endss 22 that extend horizontally in this insulation shell 2, and these conducting terminals 24 are to stretch out this welding ends 22, and be parallel to this extension block 25 upper ends, and this extension block 25 upper end vertical extent one fin 27, this fin 27 is the usefulness of contact when supplying these leads 10 with these conducting terminals 24 welding, remainder is all identical with first example structure, so no longer given unnecessary details at this.

In sum, the utility model can't effectively prevent the shortcoming that pad gets loose for improving known cable connector, promptly utilizes an extension block and increase the effect person of its stretching resistance behind mold, creates product so it is rare utility model.
