Abstract

The utility model provides a durable single-core data line, which comprises a plug jack of a first connecting line, a contact pin of a second connecting line, a PCB data line, a plastic packaging head, a connecting data line, a plug jack plastic packaging body and a contact pin plastic packaging body. Two crossed elastic members are arranged in the plug jack; the end of the contact pin is a cylindrical plug; a stop head is arranged in the middle of the plug; a travel limiting member is arranged at the back of the plug; the plug is plugged between the two elastic members to connect the plug jack and the contact pin; the stop head is clamped and embedded in the free ends of the elastic members to position the contact pin; and the elastic members are immediately reset after elastic deformation to prevent damage to the plug jack after the plug jack is used for many times. Simultaneously, the travel limiting member is arranged at the top of the open end face of the plug jack to limit the over plugging of the plug. By adopting the cylindrical plug, the stop head and the elastic members, the contact pin and the plug jack are used repeatedly without easy deformation and have firm connection and prolonged service life.

Description

Durable type list core data wire

Technical field

The utility model relates to a kind of on-deformable signal transmitted data line that repeatedly uses, and belongs to domain of communication equipment.

Background technology

At present, single core power line main body of using as main flow trend is made of jack and contact pin, wherein the end of contact pin is the spherosome plug, establish in the jack and pass through spring, rely on this spherosome plug to insert passing through in the spring of jack, reach and make jack and the affixed purpose of contact pin, but because the spherosome plug often is difficult to hold size on technology is made, make diameter differ, as easy as rolling off a log the making after repeatedly spring is passed through in insertion of spherosome plug that is not inconsistent size passed through spring generation deformation, can't be affixed with contact pin again after causing jack to be damaged, directly shortened useful life.

Summary of the invention

The technological deficiency that the utility model is repeatedly pegged graft back damage easily, can not repeatedly be utilized at existing contact pin and jack just, propose a kind of rational in infrastructure, operate easy, jack and reuse on-deformable signal transmitted data line.

For achieving the above object, the utility model is achieved by the following technical programs: a kind of durable type list core data wire, include first wiring and second wiring of mutual grafting, wherein, first wiring is made of with the jack plastic-sealed body that is connected data wire, jack, plastic packaging jack of jack the PCB data wire, plastic packaging head, the connection plastic packaging head that are connected on the pcb board; Described second wiring is made of with the contact pin plastic-sealed body that is connected data wire, contact pin, plastic packaging contact pin of contact pin the PCB data wire, plastic packaging head, the connection plastic packaging head that are connected on the pcb board; Described first wiring and second wiring are plugged in the jack by described contact pin and are formed by connecting.The both sides of described jack inner chamber are provided with the first symmetrical elastic component and second elastic component, first elastic component, one end of second elastic component is fixed on and becomes stiff end on the internal chamber wall, the other end is the free end of round end structure, and first elastic component, second elastic component extends the back and becomes chi structure, the end of described contact pin is cylindric plug, the middle part of this cylindric plug is provided with stop head, the rear portion is provided with travel limit member, cylindric plug is placed through between first elastic component and second elastic component of jack, and stop head is embedded in the free-ended round end structure, and described travel limit member overhead was on the open end of jack when contact pin and jack were pegged graft.

The further technical measures of the utility model are that the rear portion of above-mentioned jack and contact pin is respectively equipped with jack groove and the contact pin groove that is used for positioning jack plastic-sealed body and contact pin plastic-sealed body.

Compared with prior art, the utlity model has following technical advantage: contact pin adopts cylindric plug, jack adopts elastic piece structure, both are connected firmly, and unloading is convenient, and jack is not yielding, can repeatedly reuse and not damage, prolong the whole service life of data wire, reduce use cost indirectly, cheap and be easy to the realization that technology is made.

Description of drawings

Below in conjunction with illustrating and best case study on implementation is done more clearly to set forth to the utility model.

Fig. 1 is a cross-sectional view of the present utility model.

Fig. 2 is the enlarged diagram that jack combines with contact pin.

Fig. 3 is the structural representation of jack.

Fig. 4 is the structural representation of contact pin.

Among the figure: 1, PCB data wire, 2, the plastic packaging head, 3, connect data wire, 4, left wiring, 5, the jack plastic-sealed body, 6, jack, 7, first elastic component, 8, the round end structure, 9, right wiring, 10, contact pin plastic-sealed body, 11, travel limit member, 12, the jack groove, 13, second elastic component, 14, plug, 15, stop head, 16, contact pin groove, 17, contact pin, 18, inner chamber.

Embodiment

With reference to Fig. 1-shown in Figure 4, durable type list core data wire is divided into left wiring 4 and right wiring 9, the joint of left and right wiring is jack 6 and contact pin 17, both peg graft mutually, left wiring 4 also includes PCB data wire 1, plastic packaging head 2, connect plastic packaging head 2 and jack 6 be connected data wire 3, jack plastic-sealed body 5; Right wiring 9 also includes PCB data wire 1, plastic packaging head 2, connect plastic packaging head 2 and contact pin 17 be connected data wire 3, contact pin plastic-sealed body 10; PCB data wire 1 is welded on the pcb board of communication apparatus and is communicated with transfer of data.

More detailed technological improvement part is: jack 6 has the inner chamber 18 of an opening, inner chamber 18 both sides have to uneven first elastic component 7 of inclined and second elastic component 13, both are made as the shell fragment shape, one end of elastic component is fixed on and becomes stiff end on the internal chamber wall, and the other end is a free end, and this free end is a round end structure 8.The end of contact pin 17 has cylindric plug 14, the middle part of plug 14 and rear portion are provided with stop head 15 and travel limit member 11 respectively, plug 14 inserts being connected of realization jack 6 and contact pin 17 between first elastic component 7 and second elastic component 13, this moment stop head 15 just inlay card in the free end of elastic component with contact pin 17 location, two elastic components of metal material insert also through plug 14 and reset immediately after the strain, thereby even repeatedly also can prevent that jack 6 from being damaged after the action.Further, after contact pin 17 marches to certain stroke, on the open end of jack 6, and, limit the excessive insertion of plug 14 then with the sealing of the open end of jack 6 by travel limit member 11 overheads.
