Description

The microminiature coaxial connector

The utility model relates to a kind of microminiature coaxial connector, refers to a kind of microminiature coaxial connector that is used to be welded on printed circuit board (PCB) plate edge especially.

As shown in Figure 1, it is the cutaway view of a kind of existing " coaxial connector ".This coaxial connector comprise a connector 1 ', an insulation fixed body 2 ' and core terminal 3 '; This connector 1 ' bosom be provided with one the perforation 11 ', in the perforation 11 ' front side form a preposition hollow bulb 12 ', and in this perforation 11 ' rear side form a rearmounted hollow bulb 13 ', this connector 1 ' rear end left and right sides form backward respectively a pole 14 '; This insulation fixed body 2 ' be is filled at this postposition hollow bulb 13 ' inboard, this insulation fixed body 2 ' wear spliced eye 21 '; This core terminal 3 ' be to form smooth type, and be inserted in respectively this insulation fixed body 2 ' spliced eye 21 ' in, this core terminal 3 ' be establish this spliced eye 21 of an Access Division 31 ' be fixed in ' in, and this core terminal 3 ' leading portion be extend through this perforation and extend preposition hollow bulb 13 ' in, axle core terminal back segment be extend a flat welding section of stretching 32 ', smooth and be welded in printed circuit board (PCB) 4 '.Only, it has following shortcoming, for example set two poles 14 in this connector 1 ' back ' with this core terminal 3 ' welding section 32 ' be together smooth in printed circuit board (PCB) 4 ' on, so that be difficult for the location when welding, loosening easily the damage, when a complementary connector is plugged in the coaxial connector of the prior art, mating force be act on a core terminal 3 ', and this mating force directly act on the flat welding section of stretching 32 ' pad on, fragile welding position is damaged, this core terminal 3 ' be that flat backward stretching is welded on the printed circuit board (PCB), its central axis is to be positioned at the circuit board top, so its height that is positioned on the circuit board is higher, this haves much room for improvement.

So the inventor at the shortcoming of prior art, examines and goes through test improvement many times through constantly thinking to grind especially, and generation of the present utility model is arranged eventually.

Main purpose of the present utility model is to provide a kind of microminiature coaxial connector, and it is to comprise a connector, an insulation fixed body and a core terminal; This connector is a hollow cylinder, and its rear end is provided with a pair of pole; This insulation fixed body is to be filled at this connector rear side inside and to wear a spliced eye; This core terminal is to be inserted in the spliced eye of this insulation fixed body, and this core terminal mat establishes end difference and support and to make up in printed circuit board edge, more easily against the location, and can increase anti-contact engaging and separating force and increase useful life when making the welding of a core terminal and printed circuit board (PCB).

In order to make the juror can further 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 diagram only for reference with explanation usefulness, be not to be used for to the utility model limitr in addition.

To shown in Figure 4, it is three-dimensional exploded view, three-dimensional combination figure and cutaway view that the utility model is implemented illustration as Fig. 2.The utility model is to provide a kind of microminiature coaxial connector, and it is to comprise a connector 1, an insulation fixed body 2 and a core terminal 3; This connector 1 is a metal hollow cylinder, it mainly is to be made by brass, this connector 1 bosom is provided with a perforation 11, form a preposition hollow bulb 12 in perforation 11 front sides, and form a rearmounted hollow bulb 13 in these 11 rear sides of boring a hole, and this connector 1 rear end left and right sides form backward respectively a pole 14,14 '; This insulation fixed body 2 is to be filled at this postposition hollow bulb 13 inboards, and this insulation fixed body 2 wears a spliced eye 21, and this insulation fixed body 2 is to be made by insulating material such as for example Teflons; Be convexly equipped with the Access Division 31 of reversed acanthoid for example on this core terminal 3, and this Access Division 31 of mat is inserted in the spliced eye 21 of this insulation fixed body 2 and before this core terminal section be to extend perforation 11 and extend in this preposition hollow bulb 12, this core terminal back segment is to extending this connector 1, and form an end difference 32, and this end difference 32 of mat is connected to printed circuit board (PCB) 4 edges, makes this core terminal 3 and each pole 14,14 ' easily and these printed circuit board (PCB) 4 location and welds.

As shown in Figure 5, it is that of the present utility model another implemented the cutaway view of illustration.Itself and the foregoing description difference are that this end difference 32 is the turning points 321 that are provided with a bevel.

The utlity model has following advantage:

1. but this end difference of axle core terminal mat is connected to the printed circuit edges of boards, makes a core terminal easy and printed circuit board (PCB) location and welding.

2. can utilize end difference to reduce the height of coaxial connector on printed circuit board (PCB).
