Embodiment

Plug configuration one-tenth of the present invention allows that the lead that will have the conductor of one or more different types and/or size penetrates, and does not need the user to regulate.Connector has first, and this first is used for receiving lead and cooperates with second portion.Pierce through in the second portion that pin places connector.Pierce through pin and have bifurcated contact, this bifurcated contact vertically is provided with along the length of lead.When these two parts cooperated, bifurcated contact penetrated the insulating barrier of lead and can contact with the conductor in it.

With reference to figure 1-6, it illustrates the embodiment of plug of the present invention, and this embodiment is included in the plug on two straps that can be connected under the situation that does not need to use any instrument at least five different conductor sizes.Disclosed technology and method are not subjected to the restriction of the size of the conductor size that the number of lead maybe will hold.

Fig. 1 illustrates the form of angle plug 10 of the present invention.Plug comprises first 12 and second portion 14, and various piece is connected respectively on hinge 20a, the 20b.First and second parts are rotatably connected on the hinge, cooperatively interact to allow described part, as shown in Figure 1.Lead 16 as equipment can place in the plug 10.The intrinsic pin (narration hereinafter) that pierces through in the plug can be connected to the conductor in the lead on the blade 18.When plug was in as shown in Figure 4 opening, lead 16 placed in the plug 10.When hinge 20b rotated, piercing through pin can electrically contact with the conductor in the lead 16, so that conductor is electrically connected on the blade 18 at second portion.Simultaneously, lead 16 is trapped between first 12 and the second portion 14.

Fig. 5 illustrates the performance that pierces through pin 500.Each pin has bifurcated contact 502a, 502b.In the time of in pin is pressed into lead 510, pin penetrates insulating barrier 506, and the contact can electrically contact with conductor 504a, 504b.The bifurcated contact that pierces through pin can place in the bias structure of conductor on vertically, guaranteeing suitable distribution termination (wiring termination), and no matter the size of lead how.Because the size of the lead that uses in the biasing of the contact of pin, equipment tolerable plug changes.The contact can place any position along the expection cross section of conductor 504a, 504b.Longitudinal biasing between contact and lead can so that the contact than closely horizontal positioned is together when placed side by side.

Fig. 2-4 illustrates the internal arrangement of the performance of angle plug, and wherein, this angle plug can not need instrument just to be assembled into electric wire.With reference to figure 2, a series of main wall 204 vertical with leading wire casing 202 can be set, thereby lead 16 (referring to Fig. 4) is captured in the groove 202.One or more stopper rib 218 can be located at the end points place of metallic channel 202, and the length of restriction lead in plug, and makes wire termination stable.Guide wall 208 can be arranged to setover transverse to lead from the longitudinal axis of leading wire casing 202.Guiding rib 206a, 206b can be arranged to make the longitudinal axis of lead and metallic channel 202 vertically to offset away, and when assembling connector, cause lead 16 spirality structure before entering metallic channel 202.With reference to figure 4, one or more pairs of main positioning ribs 210 can make the lead bending in the metallic channel 202 and be positioned at the center.A pair of secondary positioning rib 212 can make this lead 16 crooked and placed in the middle when lead 16 enters metallic channel 202.Main positioning rib 210 and secondary positioning rib 212 can make strain relief, and help to make lead 16 to align in metallic channel 202.Rib 210,212 can help to make lead and pierce through pin 214 (referring to Fig. 3) and align, and wherein, describedly pierces through the end that pin 214 places each plug blade.Some leads 16 can have longitudinal fluting, so that insulate between the conductor in the lead.Separately rib 216 (splitting rib) can place in the plug, with when the assembling connecting piece with the conductor of this lead 16 between groove contact.Each blade 18 (referring to Fig. 1) of plug can comprise that two insulation pierce through pin 214, contacts with the insulating barrier around the conductor that pierces through lead 16 and with conductor in the lead.Piercing through pin 214 can offset away mutually, and like this, the wire spacing between the multiple size of lead and two leads is termination exactly, and does not need the user to do any adjusting.Bifurcated contact can make the location, contact along the location on the conductor length direction, therefore, one of them contact is with the conductor of contact wire.Interlocking rib 220 can be provided with in abutting connection with hinge 20a, and cooperates with complementary relative thing (not shown) when the assembling plug.Metal clip 222 can be installed in the first 12 or second portion 14 of header body, and is set on the barb (not shown), and this barb can be a body component of the mating part of plug.When the assembling plug, metal clip 222 can keep together first and second portion in the position that lead 16 enters in the plug.

Plug can adopt 16AWG lead (this 16AWG lead has two conductors of insulating barrier pattern SPT-1 (thermoplastics that service is parallel), SPT-2 or HPN (neoprene that heater is parallel)), the flat parallel cable of at least five different sizes, this cable comprise #18AWG SPT-1 and SPT-2, #16AWG SPT-2 and #18 or #16AWG HPN.Lead is pushed through the opening of metal clip 222, and enters metallic channel 202, till lead touches stopper rib 218.Spirality structure when guide wall 202 and guiding rib 206 can cause lead in being placed into metallic channel, and inwardly spur lead producing required lax of main positioning rib 210, thereby is eliminated the strain on the lead.Main positioning rib 210,212 can prevent that lead is drawn out plug.This just can provide lead 16 in plug strain relief and become the integral part of housing.When lead 16 was pushed down in metallic channel 202, main positioning rib 210 alignd the lead in the metallic channel.Secondary positioning rib 212 can help to prevent that lead from skidding off in metallic channel 202, stopper rib 218 can help to prevent that lead from sliding too far in header body.After in lead inserts metallic channel, first and second portion rotate around hinge 20a, 20b.Separately rib 216 places in the plug, thereby enters in the central recess of the insulating barrier of lead between conductor.At first 12 and second portion 14 around hinge 20a, 20b rotation so that part when cooperating with another part, separately rib 216 can be with two parts separation of lead 16, thereby helps to prevent that any lead that departs from is short-circuited passing the cable place.When closing plug, pierce through the insulating barrier that pin 214 can pierce through lead 16, and electrically contact with conductor in the insulating barrier.After lead 16 was pushed through the opening of metal clip 222, it firmly was positioned at metallic channel near rib 210,212.When first 12 that closes plug and second portion 14, roughly carry out following operation simultaneously: keep together with the first and the second portion of metal clip 222 with the cooperation of plug, and first and second portion kept in position, wherein, described metal clip 222 inwardly ejects at the top of barb (not shown).

Other embodiment are in the scope of following claims.
