Abstract

The utility model relates to an electric joint changeover connecting device. The relative faces of a conductor are respectively provided with a connector. Insulating strips are arranged between the contact terminals of the connectors and the conductor, and the surface of the contact terminal is provided with an extendible guiding part. The ends of the extendible guiding parts are respectively arranged on the periphery of the insulating strips, and simultaneously, the extendible guiding parts contacts with the surface of the conductor in a flat pasting way, so multi-variation selecting space is formed between the extendible guiding parts and welding points of the terminals of the conductor.

Description

Electrical connector conversion jockey

The utility model relates to a kind of electrical connector conversion jockey, particularly relates to a kind of switching device volume that dwindles, and reduces the printed circuit board (PCB) hole and settle, and be not subjected to the electrical connector conversion jockey of terminal distance or its row's number and shape restriction.

General printed circuit board (PCB) or conductor need to do conversion with joint usually and connect.With conventional substrate formula connector is example, sees also shown in Figure 1ly, and it normally is respectively equipped with

connector

11,12 at two end surfaces of circuit board 10 (being PCB), and constitutes a crossover sub.Because of its printed circuit board (PCB) longer, so be difficult to reduced volume.

See also shown in Figure 2ly, for commonly using wire welding type connector, it is that printed circuit board (PCB) 13 is inserted in the middle of two row's

terminals

16,17 of two side-connectors 14,15.Though it can comparatively dwindle the length of printed circuit board (PCB) 13, if it run into, and connector is provided with two rows during with upper terminal or cylindrical connector, and the crossover sub of this kind structure promptly can't be suitable for.

Seeing also shown in Figure 3ly, be No. 4618196 patent case of the U.S., be the minimum transition device that uses now, but its scope of application is comparatively narrow.For example, it is between the sub-A of printed circuit board (PCB) 18 1 sides, two abutting ends, B and need be provided with hole C, for the another terminal D of immobile phase offside.But when terminal A and D are positioned at the position of same relatively center line, fix in single hole, can't for two terminal A, D and independent function is arranged, therefore be the setting of certainly will staggering mutually of the terminal of printed circuit board (PCB) 18 both sides at circuit board, this architectural characteristic makes this kind conversion equipment be subjected to great restriction.

In addition, because employed connector has tended to compactization now, be example with the SCSI type connector of commonly using, the centre distance between its terminal and terminal only has 1.27mm, makes between both outer peritremes apart from about only surplus about 0.6mm.Because so the aperture of terminal surpasses 0.6mm usually, establishes hole be difficult to make at all again, can't fix extra terminal again, its applicability also so and limited, very undesirable.

Main purpose of the present utility model is, overcome the shortcoming of prior art, and provide a kind of electrical connector to change jockey, make it have the volume that can dwindle switching device, printed circuit board (PCB) or conductor need not to make hole, printed circuit board (PCB) has changeableization and many spaces are selected, and is not subjected to the effect of connector shape or style restriction.

The purpose of this utility model is realized by following technical scheme:

A kind of electrical connector conversion jockey, it is characterized in that it is respectively equipped with connector at the conductor opposite face, be provided with insulating trip between the contact terminal of these connectors and the conductor, and be provided with the guidance part of extension in its terminal surfaces, these guidance part ends are located at the periphery of above-mentioned insulating trip respectively, simultaneously, contact guidance part and conductive surface are smooth, and form the space of changeableization selection between conductor terminal pad and the pad.

The purpose of this utility model also can further be realized by following technical measures.

Aforesaid electrical connector conversion jockey, wherein said conductor is a printed circuit board (PCB).

The conversion jockey of aforesaid electrical connector, wherein said insulating trip are diaphragm.

Aforesaid electrical connector conversion jockey, wherein said these terminal guidance parts are located for embedding in the insulating trip.

Aforesaid electrical connector conversion jockey, wherein said insulating trip are a slice or more than a slice.

Aforesaid electrical connector conversion jockey, wherein said terminal are the conductor formation with two or more.

The utility model compared with prior art has tangible advantage and good effect.By above technical scheme as can be known.The utility model mainly is to be provided with insulating trip between connector and printed circuit board (PCB) or conductor, and the guidance part of connector and suitably extend the back crooked smooth in the above-mentioned insulating trip outside with printed circuit board (PCB) or conductor is smooth contacts, thereby form a kind of conversion equipment of new structure.The utility model is because the connector of whole conversion equipment is to being located at printed circuit board (PCB) or conductor, so printed circuit board (PCB) or conductor can effectively be dwindled, and simultaneously, also need not on printed circuit board (PCB) or conductor hole to be set, and is its advantage.Another visible largest benefit then is, because the pad of printed circuit board (PCB) or conductor two opposite end is extended to periphery electing property seam, it is more diversified to make the circuit of printed circuit board (PCB) or conductor connect design, and have the selection of a plurality of spaces, make whole conversion equipment more be applicable to the scope of design of multiple different circuit; Moreover, can find out more that according to the above technical scheme that discloses the utility model conversion equipment no longer is subjected to the shape of connector or the restriction of pattern, can be changed connection easily, really be quite novel with a practical improvement design.
