Description

The Wedge-shape connector that has the penetration insulator of sealing

The present invention relates to a kind of electrical connector, more specifically to a kind of Wedge-shape connector.

The application No.EP0810688 of EUROPEAN PATENT OFFICE discloses a kind of Wedge-shape connector of insulation-piercing conductor.UK Patent Application No.2065994 also discloses a kind of Wedge-shape connector that has the wedge that can pierce through the insulator on the conductor.U.S. Patent No. 5,679,031 discloses the maintenance bar on the Wedge-shape connector housing.

According to one embodiment of present invention, provide a kind of Wedge shape electric connector, comprised a housing and a wedge assembly.The wedge assembly is suitable for inserting in the housing two electric conductors is electrically connected to each other.The wedge assembly comprises that the conductor insulation body on a framework, the framework penetrates protrusion and at least one is around the seal that penetrates protrusion.The size and dimension of protrusion makes it can penetrate conductor to be electrically connected with the current-carrying part of conductor.This at least one seal forms a sealing around protrusion between conductor and framework.

According to a further embodiment of the invention, provide a kind of Wedge shape electric connector, comprised a housing, a wedge and at least one conductor bed course.Wedge is suitable for inserting and makes two conductors machinery and electrical connection each other in the housing.The size and dimension of this at least one conductor bed course makes it can be between inboard and one first conductor of housing.Bed course prevents that when first conductor is mobile to the inside in the process of wedge being inserted in the housing housing from damaging the insulator of first conductor.

A method according to the present present invention, provide a kind of in a Wedge-shape connector method with two conductors electricity and mechanical connection, wherein the wedge shape connection has a housing and a wedge, and the method may further comprise the steps: provide a framework and a conductor insulation body ledge to wedge; Seal is positioned on the wedge, makes seal center on conductor and penetrate ledge; And wedge inserted in the housing, two conductors are positioned on the wedge opposite side.Ledge penetrates in the conductor and seal forms sealing around ledge between conductor and wedge framework.

Describe above-mentioned aspect of the present invention and further feature in detail below in conjunction with accompanying drawing, wherein:

Fig. 1 has two conductors of feature of the present invention and an exploded perspective view of a Wedge-shape connector;

Fig. 2 is an exploded perspective view of the wedge shown in Fig. 1; And

Fig. 3 is the cutaway view along conductor shown in the 3-3 line among Fig. 1 and connector assembly.

Referring to Fig. 1, show one and have a Wedge shape electric connector 10 of feature of the present invention and the exploded perspective view of two conductor A, B.Although the present invention single embodiment with reference to the accompanying drawings is described, should understand the version that the present invention can show as many embodiment.In addition, can use any suitable size or unit type or material.

Conductor A, B generally include a current-carrying part C and an outer electrical insulating material D in one.Connector 10 generally includes a housing 12, one wedge assemblies 14, seal 16 and bed course 18,19.The monomer spare that housing 12 preferably is made of metal.Housing 12 has the cross section that is generally C shape and reduces gradually from back to front to form a structure that is generally wedge shape." C " shape forms two at the relative end face of housing and the

conductor receiving area

20,22 of bottom surface.Have lockhole 24 at this embodiment end face and bottom surface, this is further described below.But in the embodiment that changes, can use the housing of other type.

Wedge shape assembly 14 comprises a framework 26 and insulation penetrating member 28.With reference to Fig. 2, framework 26 is made of two

parts

30,32 that connected by the securing member (not shown) to each other in this embodiment in addition.But in the embodiment that changes, can use the framework of other types.First frame parts 30 has a groove 34 and a side recess 36 that is installed in penetrating member 28.Second frame parts 32 has an inboard boss 38 and an outside boss 40.Inboard boss 38 is suitable for and side recess 36 locking cooperation mutually.Two

frame partss

30,32 form the end face and the

bottom surface

42,44 of arc.Framework 26 has a structure that is generally wedge shape from front to

back.Frame parts

30,32 both can also can be made up of non-conducting material electric conducting material.

The penetrating member 28 that insulate in this embodiment is two bar bars being made by electric conducting material.But the penetrating member of other type and quantity can be set, in the embodiment that changes for example with the integrally formed penetrating member of framework or not exclusively run through frame height and extend and make framework play the penetrating member of an electric bridge effect.Bar bar 28 is basic identical in this embodiment, but highly different.Each bar bar 28 has apical tooth and an

end tooth

46,48 and a side recess 50.Bar bar 28 is arranged in groove 34, and when two

frame partss

30,32 were connected with each other, the inboard boss 38 of second frame parts 32 stretches in the side recess 50 to be locked bar bar 28 in the framework 26.The opposite end that

tooth

46,48 stretches out groove 34.In the embodiment that changes, framework 26 can groove on bar bar 28.Seal 16 also can groove built on the framework 26 and/or on the bar bar 28.

Seal 16 preferably is made of a kind of elastomeric material, for example rubber or polymer.Each seal has hole 52, and its size and dimension makes and can be passed by tooth 46,48.Seal 16 has arcuate shape with on the

curved surfaces

42,46 that is located in framework 26 and provide and hold the arc-shaped contact surface 54 meet conductor A,

B.Bed course

18,19 is preferably made by plasticity or polymeric material.Each

bed course

18,19 has one

first side

56,58 that has curved surfaces that contacts with conductor A, B and one second

opposite flank

62,64 that has projection 60.Second side, 62,64 cambers are installed in into

housing receiving area

20,22 with cooperation.Projection 60 size and dimensions are made in the hole 24 of the housing 12 of can packing into vertically to

pin bed courses

18,19 with respect to housing 12.But in an embodiment who changes, can provide variation, other or not have lock-in feature.In a preferred embodiment,

bed course

18,19 can be selected from the many different bed course size and dimension corresponding to the conductor A that will connect, B size.

With reference to Fig. 3, wedge connector 10 is shown in addition, two conductor A, B are connected with each

other.Bed course

18,19 is between conductor A, B and housing 12.

Bed course

18,19 can help prevent that housing 12 is careless to be damaged the insulating barrier D on conductor A, the B and can help to make conductor A, B to locate relative to each other to provide wedge assembly 14 suitable mechanical connection.Projection 60 is arranged in hole 24 and puts in place so that

bed course

18,19 is vertically locked.When wedge assembly 14 inserted, the

tooth

36,38 of bar bar 28 passed the insulating barrier D of conductor A, B and electrically contacts with current-carrying part C.Seal 16 can be depressed and form sealing around bar bar 28 between framework 26 and conductor A, B.Like this, bar bar 28 forms electrical connection between conductor A, B, is the electrical connection of a sealing but connect.In the embodiment that changes, can use greater or less than two seals and/or greater or less than two bed courses.

Should understand the above-mentioned just description exemplary to the present invention.Those of ordinary skills can carry out many variations and modification without departing from the scope of the invention.Correspondingly, the present invention can comprise all these variations, modification with different, and they all fall within the scope of claim.
