Abstract
The invention discloses a connecting needle for a wired fixture. The connecting needle consists of a metal part and an insulating plastic part, wherein based on the service direction, the insulating plastic part is positioned on the tail part of the connecting needle; the insulating plastic part forms a head part and a tail part; the cross section of the head part is bigger than that of the tail part; the bottom end of the tail part has a tapering cone shape; the cross section of the metal part is smaller than that of the tail part of the insulating plastic part; and the metal part is inserted into the tail part of the insulating plastic part and is fixedly accommodated in the insulating plastic part, so that the tenacity and bending coefficient of the tail part of the connecting needle are increased. Therefore, the tail part of the connecting needle knocked into a needle plate of the fixture can be effectively prevented from breaking; and since the tenacity is increased, the size of the insulating plastic can be reduced, the connecting needle occupies small area of the needle plate of the fixture and the use ratio is high.
Description
Technical field
The present invention relates to a kind of connection pin, be used to connect wired tester probe and tester table interface.
Background technology
At present, known connection pin is made up of two parts, the one, the metal part, the 2nd, insulation plastic cement part, metal partly inserts in the insulation plastic cement part certain depth, be generally 8mm, be that metal partly inserts in the head part of insulation plastic cement, the cross-sectional diameter of insulation plastic cement head part is generally 3mm, the diameter of section of insulation plastic cement afterbody part is generally 2.2mm, described afterbody part bottom is that the progressive pyramid type that dwindles forms tip-like, therefore strike the just insulation plastic cement afterbody part of diameter of section 2.2mm in the needle plate the inside of tool, if when moving the connection pin, do not note to make afterbody partly to break, cause unnecessary trouble to test, the centre distance of the connecting hole that bores is generally 3.8mm on the needle plate of tool in addition, connecting pin like this strikes behind the needle plate the inside, its spacing becomes the 0.8mm free space, unwrapping wire just has a lot of troubles for the more tool of pin mark, to take up room because of connecting the pin external diameter in addition, just have no idea to put at the local existing connection pin of the insufficient space 3.0mm of the intensive place of pin mark like this, just can't utilize naturally this connects the corresponding resource in pin position.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of connecting needle for wired fixture, have toughness and anti-tortuosity factor preferably, can prevent effectively that the afterbody that connects pin from fractureing, and its to take the needle plate space less, utilization factor is higher.
The present invention for the technical scheme that solves its technical matters and adopt is:
A kind of connecting needle for wired fixture, partly form by metal part and insulation plastic cement, to use direction to be benchmark: the insulation plastic cement partly is positioned at the connection Aculeata, described insulation plastic cement partly forms head part and afterbody part, the xsect of head part is greater than the xsect of afterbody part, the bottom of described afterbody part is progressive dwindle coniform, the xsect of described metal part is less than the xsect of the afterbody part of insulation plastic cement part, and described metal partly wears the afterbody part of described insulation plastic cement part and fixedly is placed in the described insulation plastic cement part.
Further technical scheme of the present invention is:
Described metal partly wears to the afterbody part of described insulation plastic cement part and the intersection of described bottom.
The afterbody part cross-sectional diameter of described insulation plastic cement part is 1.4mm; The cross-sectional diameter of the head part of described insulation plastic cement part is 1.5mm.
The invention has the beneficial effects as follows: because metal partly wears the afterbody part into insulation plastic cement part, increased and connect the toughness and the anti-tortuosity factor of Aculeata, thereby can effectively prevent to knock in fractureing of connection Aculeata in the tool needle plate; Again because the enhancing of its toughness, and realize dwindling of insulation plastic cement part specification, make to connect pin to take tool needle plate space less that utilization factor is higher.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Embodiment: a kind of connecting needle for wired fixture, form by metal part 1 and insulation plastic cement part 2, to use direction to be benchmark: insulation plastic cement part 2 is positioned at the connection Aculeata, described insulation plastic cement part 2 forms head part 21 and afterbody part 22, the xsect of head part 21 is greater than the xsect of afterbody part 22, the bottom 23 of described afterbody part 22 is progressive dwindle coniform, the xsect of described metal part 1 is less than the xsect of the afterbody part 22 of insulation plastic cement part 2, and described metal part 1 wears the afterbody part 22 of described insulation plastic cement part 2 and fixedly is placed in the described insulation plastic cement part 2.
Described metal part 1 wears to the afterbody part 22 of described insulation plastic cement part 2 and the intersection of described bottom 23.
Afterbody part 22 cross-sectional diameters of described insulation plastic cement part 2 are 1.4mm; The cross-sectional diameter of the head part 21 of described insulation plastic cement part 2 is 1.5mm.
According to the foregoing description, the connection pin of total length 47.3mm is an example after the bottom length to remove: the partly long 47.3mm of metal, the insulation partly long 19.7mm of plastic cement (removal bottom length), the partly long 12mm of head of the plastic cement part that wherein insulate, the partly long 7.7mm of afterbody (removal bottom length) of insulation plastic cement part, metal partly insert insulation plastic cement part 19.7mm.
During concrete enforcement, the afterbody (the afterbody part 23 of the plastic cement that promptly insulate) that connects pin is in the needle plate of wired fixture is knocked in the bottom, the intersection of metal part 1 that exposes and insulation plastic cement part 2 is around lead, this lead is connected with the probe of wired measurement jig, and exposed metal part 1 head end is connected with the tester table interface fit.
Because metal part 1 wears afterbody part 22 into insulation plastic cement afterbody part 2, increased and connected the toughness and the anti-tortuosity factor of Aculeata, thereby can effectively prevent to knock in fractureing of connection Aculeata in the tool needle plate; Again because the enhancing of its toughness, and realize dwindling of insulation plastic cement part specification, make to connect pin to take tool needle plate space less that utilization factor is higher.
