Connector

Technical field

The utility model is about a kind of connector, refers to especially a kind ofly not only make to go up very conveniently, can effectively reduce cost of manufacture, and can reach easily and electronic installation between the connector that electrically connects.

Background technology

All be provided with the connector of different size and different aspects on the general electronic installation, this connector is to electrically connect with this electronic installation, and peg graft for the terminal on other electronic peripheral device, reach the purpose of transmitting electric signal with other electronic peripheral device mutually.

Please referring to shown in Figure 7, traditional connector 60 mainly includes a body 61 and a center needle 62, and wherein these body 61 front ends are to be formed with a jack 610; This center needle is rounded cylinder, and it is arranged in this jack 6

Among 10, and the mutual riveted in rear end and body 61 rear ends; So, then the terminal (not shown) of other electronic peripheral device of conforming to of specification can be inserted and be interconnected with center needle 62 by the jack 610 of body 61;

Yet this traditional connector 60, because its center needle 62 is rounded cylinders, and be to borrow riveted mode and body 61 to interconnect, so its service time one long afterwards, tend to produce gradually loosening and rolling among body 61, and then cause connecting unsteady situation generation.

In view of this, developed again afterwards and another kind of connector 70, please referring to shown in Figure 8, it is to include a body 71 and a center needle 72, wherein these body 71 front ends are recessed into and are formed with a jack, and the rear end penetrates and is formed with a fixing hole 710, this fixing hole 710 be communicate with jack and with the same axle center of jack, its cross section is to be hexagon; In addition these body 71 bottoms are formed with a clamping hole, this clamping hole be transverse to fixing hole 710 and with fixing hole 71

0 communicates, and is equipped with a fixing sheet 73 in this clamping hole;

This center needle 72 is by hexagonal metal cartridge turning moulding, and it is formed with an a junction 720 and a fixed part 721, and wherein the terminal of this connecting portion 720 other electronic peripheral device that can conform to for specification connects; These fixed part 721 cross sections are to be hexagon with respect to fixing hole 710, and in corresponding to the radially recessed caulking groove 722 that is formed with in clamping hole place; This center needle 72 is to be arranged among the body 71, be positioned among the jack with connecting portion 720, and fixed part 721 is through within the fixing hole 710, engages mutually with fixing hole 710; In addition, its caulking groove 722 is chimeric mutually with aforementioned fixing sheet 73.

By this, the connector 70 of the prior art can prevent effectively that this center needle 72 from producing rolling among body 71, and prevents this center needle 7

2 produce axial slip among body 71, thereby make this center needle 72 firm being positioned among the body 71.

But, the

connector

60,70 of aforementioned prior art, it desires to electrically connect with electronic installation, often must install between the rear end that is connected in this electronic installation and

center needle

62,72 with lead or scolding tin, this need spend certain hour and manpower is finished, and therefore uses comparatively inconvenient; In addition, the center needle 72 of connector 70 is made in the turning mode, is comparatively time-consuming, palpus secondary operations when especially making abnormity, and cost more greatly improves, so the connector cost of manufacture of prior art is difficult for reducing.

The utility model content

The purpose of this utility model provides a connector, and it not only makes very convenient, can effectively reduce cost of manufacture, and can reach easily and electronic installation between electric connection.

For reaching aforementioned purpose, connector of the present utility model is to include a body and a center needle, and wherein this body is formed with a jack and a cross section is non-circular fixing hole; And this center needle is by die casting and straight forming has a junction, a fixed part and an electrode pin, and it is to be arranged among the body, is fixed mutually with the fixing hole of fixed part and body; And this electrode pin is to be shaped in the other end of this fixed part with respect to this connecting portion, and it is piercing in outside the fixing hole of body, and is extended with certain-length.

The beneficial effects of the utility model are, the user can be when installing connector of the present utility model, directly make this electrode pin and electronic installation reach electric connection with scolding tin or other means, it need be by complicated operation sequence, therefore also lead setting that must be not other is used upward more convenient.

And because aforementioned center needle is to finish the moulding of connecting portion, fixed part and electrode pin by die casting and with the time, it is comparatively time saving and energy saving, therefore the reduction that can effectively reach cost of manufacture.

Embodiment

Please referring to Figure 1 and Figure 2, connector of the present utility model includes a body 10, a housing 20, plural power connecting sheet 30 and a center needle 40, wherein:

This body 10 be for plastic material made, its inside is formed with plural ostiolate room 100, and front end is recessed to be formed with a jack 11, and the rear end penetrates and is formed with a fixing hole 12, this fixing hole 12 be communicate with jack 11 and with jack 11 same axle center, its cross section is to be hexagon; These body 10 bottoms are formed with a clamping hole 13 (please cooperate referring to shown in the 4th figure) in addition, this clamping hole 13 is to be transverse to fixing hole 12 and to communicate with fixing hole 12, and be equipped with one in this clamping hole 13 and fix sheet 14, these fixing sheet 14 width are corresponding with clamping hole 13, its edge with respect to fixing hole 12 is recessed on and is formed with an embedding edge 140, and the two ends of this embedding edge 140 are rough outstanding and form card division 141;

This housing 20 is to be sheathed on this body 10 outsides, and has a protecgulum 21 and can cover and close in this body 10 front ends, and wherein, this protecgulum 21 has a perforation 210 and can expose for jack 11;

This plural number power connecting sheet 30 is to be arranged among the room 100 of body 10, has an end respectively and is connected in the external circuit (not shown); And the other end is exposed in the jack 11 of body 10, for being connected with other electronic peripheral device (not shown);

This center needle 40 is by die casting and straight forming, and it has a junction 41, a fixed part 42 and an electrode pin 43, and wherein the terminal of this connecting portion 41 other electronic peripheral device that can conform to for specification connects; These fixed part 42 cross sections are to be hexagon with respect to fixing hole 12, and in corresponding to the radially recessed caulking groove 420 that is formed with in clamping hole 13 places; This electrode pin 43 is in this center needle 40 die casts simultaneously, is shaped in the other end of this fixed part 42 with respect to this connecting portion 41, is vertically down to bend and extend certain-length;
