Description

Cable connector

The utility model relates to a kind of cable connector, and it has press button for a kind of locking device reed, can cooperate the assembling of cable connector hull shape inlay card, and cable connection engages firmly with the connector contact, can not use the cable connector that comes off because of plug.

Existing cable connector, generally comprise, upper and lower casing, one is connected the cable be positioned between upper and lower casing, is communicated with cable and inserted terminal is exposed to the external connector of upper and lower shell, and is located between upper and lower casing and can operates the locking device that is used for the butt connector joint outward by housing.Wherein in locking device, be used for the reed that butt connector engages need be disposed a button, the joint of its pressing action may command reed with open, with regard to assembling and cost, use reed and button, not only cost is high and increase assembling man-hour.Also there is following shortcoming in the existing cable connector in addition:

(a) wiring and contact be easy to come off-because the contact of cable connection and cable connector is tiny, therefore welding is not easy, must plug in the actual use of cable connector, wiring only depends on welding with combining of contact, can't effectively prevent under the directly stressed situation of wiring, plug back wiring for several times and contact come off easily, can't continue to use;

(b) the conducting effect stability not enough-because the housing of existing cable connector is with screw lock mode or the combination of engaging mode, actual use a period of time after bolt can get loose gradually, the engaging mode in conjunction with the time adaptation bad;

(c) connector part maintenance maintenance can't carry out-because after the existing cable connector welds with contact, must will coat with insulating material, prevent short circuit, prior art is to carry out in the encapsulating mode, practical operation is not only time-consuming takes a lot of work, and because of encapsulating strength can thrust wiring, in case damage can only be scrapped and can't repair;

When (d) cable connector is used for particular system, be to be fit to the use of various objectives, it is provided with in connector debates that to know key be fixed design, and this fixed setting is difficult to change and deacclimatizes various objectives.

The purpose of this utility model is to provide a kind of cable connector, and reed has particular design in its locking device, except that having engagement function, also has the knob of pressure function, and has the stretching resistance design, can also change and debate the position of knowing key.

The purpose of this utility model is to realize like this, a kind of cable connector promptly is provided, it comprise can cover up and down one on, lower house, one cable, be connected and be positioned at an aforementioned side that goes up lower house, a connector, be connected with aforementioned cable, its inserted terminal is exposed to outside the lower house, and a locking device, be positioned at, between lower house, described locking device comprises a pair of reed, described reed has a location division, an one press button portion and a junction surface, described location division is fixed on the cable connector housing, and described press button portion is outside the outline along the cable connector housing is convexly set in from described location division, and extend from press button portion at described junction surface, be stuck in outside the cable connector housing, keep an elasticity spacing with housing.

The advantage of cable connector of the present utility model is, it is convenient to control, and it is convenient to make, and in conjunction with firm, conduction is stable, and is easy to change and debates the knowledge key position to adapt to various objectives.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:

lower casing

1,2 after the welding.In addition, lower house 2 inboard both sides are provided with L type inserting slot 23,24 (13,14), and nearly both sides, composition surface, stage casing are provided with breach 25,26 (15,16), all are used to inlay card locking device 5, and the back also can be narrated.Have, it is chimeric for cable 3 and connector 4 that the both sides up and down of lower house 2 are provided with embedding mouth 27,28 (17,18) again.

Cable 3 is common cable, and its abutting end is provided with connecting portion 30, two convex shoulders 301,302 about on this connecting portion 30 there being mold casting forming, and this two convex shoulder all has

upper rim

3011,3021 and lower rim 3012,3022.These electric wires in the cable 3 are to connect by circuit board 31 and connector 4 solid weldings.In addition, this lower house 2 and two convex shoulders 301,302 are provided with fit portion, are used for that both are made effective fit and fix, and this fit portion is positioned on the lower house 2 of neighbour's embedding mouth 27, are provided with two drag posts 291,292 (191,192) arranged side by side; On two convex shoulders 301,302, establish

drag hole

3013,3023, so, when this drag post 291,292 (191,192) is inserted in the

drag hole

3013,3023, cable 3 is firmly combined with last

lower house

1,2 have good stretching resistance.In brief, when these cable 3 tensions, this pulling force can reach convex shoulder 301,302, and can not have influence on combining of cable 3 and circuit board 31 contacts.

As shown in Figure 1, the utility model device is provided with the portion of pushing against on the lower house 2 of contiguous drag post 291,292 (191,192) upper and lower, and this portion that pushes against establishes barricade 293 and 294 (193 and 194) on lower house 2.As shown in Figure 3, after cable 3 is incorporated into lower house 2, can know that

drag hole

3013,3023 covers of finding out on two convex shoulders 301,302 are stuck in drag post 291,292 (191,192), the

upper rim

3011,3021 of convex shoulder 301,302 and

lower rim

3012,3022 are resisted against on the barricade 293 and 294 (193 and 194), therefore all around all effectively being located of this cable 3 can guarantee that the cable 3 and the contact of circuit board 31 avoid directly stressed.Equally, as shown in Figure 4, electric connector 4 one ends also are provided with clamping close device 6, this clamping close device is established engaging groove 295 (195) on lower house 2, the corresponding engaging post 42 that is provided with this connector, by this groove 295 (195) with engage post 42 and engage, can make connector 4 have the tension effect, so this setting that pushes against portion and clamping close device 6 can make cable and connector have Hangzhoupro and draw ability, in conjunction with firm.
