Description

Connector

[technical field]

The utility model is about a kind of connector, particularly about a kind of connector of guaranteeing the certain ground connection of copper ring.

[background technology]

Be a kind of known message connector as shown in Figure 7, this connector comprises a housing 70, a copper ring 80 and an earthing member 90 (please cooperate consult shown in Figure 8) at least; Wherein:

This housing 70 is general rectangular and be hollow form, and the one end is formed with the outstanding protuberance 71 of outer wall on one day, forms jacks 72 in this protuberance 71, for the ccontaining aforementioned copper ring 80 of installation; Earthing member 90 is the metal lamellar bodies of shape of generally taking the shape of the letter U again, and it has two relative arms, and wherein the medial extremity of an arm extends the electrical contacts 91 of a bending to the inside, and the medial extremity of another arm then extends outwardly to constitute a pin 92 with right angle orientation; Moreover the root edge place of earthing member 90 outboard ends stretches out and forms a tongue piece 93; And this earthing member 90 is ends of being located at nearly protuberance 71 in the housing 70, and its electrical contacts 91 is positioned at correspondence in jack 72 inboards, and its pin 92 passes outside the housing 70, and for the usefulness of plug-in unit assembling, the tongue piece 93 of earthing member 90 then extend out on the inner hole wall of jack 72.

These copper ring 80 external diameters and jack 72 internal diameters coupling, its medial extremity is formed with the expansion portion 81 that a tool inclined-plane and its maximum outside diameter are slightly larger than jack 72 internal diameters, whereby, copper ring 80 medial extremitys still can successfully enter in the jack 72, in copper ring 80 enters jack 72 fully, its expansion portion 81 will clamp-on the hole wall of jack 72, and constitute tight fit state (seeing also shown in Figure 9); At the same time, the medial extremity of copper ring 80 also contacts with tongue piece 93 formations of earthing member 90.

From the above, the copper ring 80 of aforementioned connector must electrically contact with earthing member 90 formations, yet the contact relation of the two only terminate in tongue piece 93 that earthing member 90 outboard ends are extended and and copper ring 80 medial extremitys between very limited contact area, because the message connector has current signal regularly by copper ring 80 and earthing member 90 when using, therefore may elevate the temperature, when temperature one height, the possibility that produces deformation promptly heightens relatively, under this situation, earthing member 90 promptly may come in contact bad situation with copper ring 80, and then influences the operate as normal of connector.

[utility model content]

The utility model main purpose is to provide a kind of connector of guaranteeing that copper ring and earthing member contact really.

For reaching the major technique means that aforementioned purpose takes is to make aforementioned connector include:

One housing, general rectangular and be hollow form, the one end is formed with the outstanding protuberance of outer wall on one day, formation one jack in this protuberance;

One copper ring is to be located in the jack of aforementioned housing, is formed with the recessed neck of a circular groove shape on this copper ring medial extremity;

One earthing member, this earthing member one end is formed with a contact chip respectively in two relative positions, and two contact chips are fitted on the recessed neck that is held on copper ring relatively and are constituted and electrically contact;

In the previous constructions, two contact chips in the earthing member are the recessed necks that are held on relatively on the copper ring, electrically contact so can guarantee that copper ring and earthing member positively constitute, and can not influence its contact relation because of high temperature deformation or external force.

[embodiment]

A preferred embodiment of the present utility model sees also shown in Figure 1, mainly is to be arranged with a copper ring 20 and an earthing member 30 in a housing 10; Wherein:

This housing 10 is general rectangular and be hollow form, and the one end is formed with the outstanding protuberance 11 of outer wall on one day, forms jacks 12 in this protuberance 11, and for ccontaining this copper ring 20 of installation, these jack 12 medial extremitys form the slot part 13 that inwardly concaves on relative hole wall.

This earthing member 30 has upper and lower and two lateral plates, wherein a lateral plate and last slice be to be the disconnection shape, other each sheets then are continuous shape, again earthing member 30 wherein the medial extremity of a lateral plate extend the electrical contacts 31 of a bending to the inside, the medial extremity of another lateral plate then extends outwardly to constitute a pin 32 with right angle orientation; Moreover, earthing member 30 thereon, down the outboard end of sheet stretches out respectively and forms a contact chip 33, be formed with the space between the free end of this contact chip 33 and upper and lower, make it form a shell fragment shape, contact chip 33 forms outstanding contact site 330 respectively on the relative inner face again.

Aforementioned again earthing member 30 is ends of being located at nearly protuberances 11 in the housing 10, and the contact chip 33 on its upper and lower is the slot parts 13 that are positioned on jack 12 medial extremitys, and its electrical contacts 31 is to be positioned at jack 12 inboards, and its pin 32 passes outside the housing 10.

These copper ring 20 external diameters and jack 12 internal diameters coupling, its middle section is formed with the expansion portion 21 that a tool inclined-plane and its maximum outside diameter are slightly larger than jack 12 internal diameters, its medial extremity then is formed with one and inwardly concaves and dwindle the recessed neck 22 of internal diameter, and this recessed neck 22 is suitable corresponding to two contact chips 33 on the earthing member 30.

Can understand the detailed construction of the utility model one preferred embodiment by above-mentioned explanation, detailed as described below as for its compound mode:

At first copper ring 20 is pressed in the jack 12 of housing 10, when copper ring 20 enters jack 12, its expansion portion 21 will clamp-on the hole wall of jack 12 to constitute tight fit.Then earthing member 30 is inserted by the opening on housing 10 sidewalls, and it is installed in an end of nearly protuberance 11 in the housing 10, the contact chip 33 at its upper and lower outboard end place will be positioned at the slot part 13 (seeing also shown in Figure 2) of jack 12 medial extremitys simultaneously, and two contact chips 33 will be corresponding to the recessed neck 22 of copper ring 20, its contact site 330 and with relative clamping on it (seeing also shown in Figure 3), to constitute certain relation that electrically contacts.

Seeing also again shown in Fig. 4,5,6, is the another preferred embodiment of the utility model, and its basic composition structure is all roughly the same with last embodiment as housing 10, copper ring 20 etc., and difference is in the contact chip 33 ' form of this earthing member 30 ' slightly different:

This earthing member 30 ' mainly still has upper and lower and two lateral plates, and its outboard end of upper and lower also stretches out respectively and forms a contact chip 33 ', this contact chip 33 ' is to be long and narrow, its long limit is parallel with upper and lower edge, and and form the gap between upper and lower, make it form a shell fragment shape, the long edge tail of contact chip 33 ' slightly bends inwards to constitute contact site 330 ' again.When earthing member 30 ' is packed housing 10 into, earthing member 30 ' will be positioned at an end of housing 10 nearly protuberances 11, and its contact chip 33 ' will be positioned at the slot part 13 on jack 12 medial extremitys, and the contact site 330 ' of this contact chip 33 ' will be held in the recessed neck 22 of copper ring 20 then relatively to constitute certain electrically contacting.

From the above, connector of the present utility model is that to make two contact chips in the earthing member are the recessed necks that are held on relatively on the copper ring, can make copper ring and earthing member positively constitute whereby electrically contacts, thus, can avoid influencing its contact relation, effectively solve the problem that traditional connector may influence operate as normal because of loose contact because of high temperature deformation or external force.
