Description

The wire and cable connector device

The utility model is a kind of wire and cable connector device, relates in particular to that a kind of cable still keeps the origin-location under tension and unlikely fracture, the wire and cable connector device deviate from.

Along with more and more widely reaching, the scope of computer applications the user can be utilized expediently immediately plant computer respectively the additional function that is provided, usually on computers can winding there be many peripheral equipments to support these functions are provided, as printer, scanner, digital still camera etc., yet in order to make computer can directly control the transmission of these peripheral equipments and signal steadily, it is indispensable providing in conjunction with firm cable and the electric connector that cooperated thereof.Especially for portable notebook computer, along with they are residing local different, will use different peripheral equipments, at this moment, strongly durablely just just become considerable essential the outfit again at the wire and cable connector device of plug.Wire and cable connector device on the market is of a great variety at present, size, size has difference respectively, be assembled in mode on the cable according to connector, roughly can be divided into two types, first type as United States Patent (USP) the 4th, 993,971,5,011,424,5,435,744,5,486,117,5,562,497,5,569, documents such as No. the 79209545th, No. 047 and TaiWan, China patent, its wire and cable connector device 6 mainly is provided with a metallic inner casing 60 (with reference to Fig. 4), and these inner casing 60 formed inner spaces can be accommodated and winding electric connector (not shown) and cable ends 62, and finish metal inner casing 60 after the winding and need give in the Jet forming machine directly injection moulding one deck insulation shell 61 outside shell again, borrow this insulation shell 61 with integral body of the affixed formation of the insulation appearance of metal inner casing 60 and cable ends 62.These designs have intensity preferably usually, insulation shell 61 can effectively support cable ends 62, the situation that makes it be unlikely when contact engaging and separating force is excessive and fracture takes place or get loose between electric connector, yet, owing to need the metal inner casing is inserted in the Jet forming machine injection moulding forming an integral body, so manufacturing cost and specification requirement are all higher.And, under the situation that insulation shell covers the metal inner casing fully, in case have inner member to damage or during the cable wire fracture, can't repair easily it at all, as long as problem is arranged slightly, just sliver cable connector device must be abandoned replacing like this, cause user's cost burden.

Other class design is by United States Patent (USP) the 5th; 234; No. 357 and the curved patent the 77210069th of Chinese platform; 79108915; 80203860; wait for No. 83214112 document to disclose like that; with reference to No. 83214112 document of TaiWan, China patent shown in Figure 5; its wire and cable connector device 7 mainly be provided with metal on; lower house 71; 72; two housings is to borrow screw interlocking mode to form a box-like body; and portion forms a receiving space to accommodate electric connector 74 within it; simultaneously the box-like body rear side be formed with a perforate 75 for the terminal lead 41 of cable 4 by so that winding on electric connector 74; because the cable ends lead 41 that is connected on the electric connector 74 is very tiny usually; therefore make its unlikely and electric connector 4 disconnections for further fixed cable 4 to protect these leads 41; lower house 72 appropriate positions in cable 4 both sides are respectively equipped with spiral shell seat (not shown); have the holding piece 76 of arc bending with the common bridge joint central authorities that lock, borrow the arc bending of this holding piece 76 to support on the insulated part 40 of cable ends and cable can be fixed on the lower house.These design biggest advantage are easy to assembly, and laid-up is easy, can save the cost that must change whole wire and cable connector device because of little defective.But this type of wire and cable connector device is bad to vertical fixed effect of cable, as long as the user firmly pulls cable, it is external just may to cause cable ends longitudinally to be subjected to force direction to deviate from upper and lower shell, and then terminal wire fracture was lost efficacy.In addition, the insulated part in the cable outside is directly to contact with metal upper and lower casing, and insulated part perforate peritreme easy and lower house rubs, and gets off for a long time, insulated part often has wearing and tearing to break, even exposes inner lead and cause situation of short circuit to take place.At last, such connector is when the earth lead of winding cable, must on housing, establish a spiral shell seat in addition to borrow screw with this earth lead locking, like this, except that the program of original winding cable, need increase the course of processing of interlocking earth lead in addition, and must just can reach, be unfavorable for a large amount of mechanization productions like this by manual method.

Main purpose of the present utility model, be to provide a kind of winding facility, maintenance easily and cable ends when bearing the sizable power of pullling and do not rupture or deviate from the wire and cable connector device of shell.

An other purpose of the present utility model is to provide the wire and cable connector device a kind of design of isolating cable and its metal shell, makes unlikely directly the contact with metal shell of cable rub and cause short circuit.

Another purpose of the present utility model is by the two metal shell windings of wire and cable connector device in one, in the lump with the earth connection clamping of cable and constitute electrical path, with the be spirally connected process of earth connection of minimizing, make a large amount of production and assembly processes more easy, convenient, and can strengthen the effect of anti-stop signal interference and ground connection simultaneously.

The purpose of this utility model is to realize like this, this wire and cable connector device mainly includes the metal shell that covers, this covers shell has two and covers and form the inner space each other to accommodate the upper and lower cover body of connector body and cable ends, the connector body installing and locating extends inward into connector body with its terminal formation to electrically conduct and the line of cable is terminal from the junction that covers shell at the opening part that covers shell butt joint side.Injection moulding has positioner on cable ends, this positioner has to hold and is covering supporting convex body and deciding stops on the outer casing inner wall, and section is provided with annular groove therein, like this, borrow and cover covering of shell two lids, make cable ends directly borrow this positioner to be fixed on the junction that covers shell, and the earth lead in the cable and metal knitted body also can be combed and be clamped in the lump in the annular groove of positioner after whole, and utilize and to cover that the corresponding clamping device that is provided with of institute is gripped on the shell, with the formation grounded circuit.

Compared with prior art, the utlity model has following advantage:

1. because the setting of cable ends positioner, thereby can effectively strengthen the enabling capabilities of cable at longitudinally.

2. by isolating the design of cable and its metal shell, can prevent effectively that cable from directly contacting friction and causing short circuit or improper fracture with metal shell.

3. reduced winding process or manufacturing process, made that assembling process is more prone to, facility.

Below in conjunction with drawings and Examples the utility model is further described.
