Embodiment 1
The utility model embodiment provides a kind of power lug, and as shown in Figure 1, described power lug comprises: rubber-covered shell 1 and the copper wire connecting portion 2 be positioned on the upside of described rubber-covered shell 1 inwall.
Described copper wire connecting portion 2 comprises: copper shell fragment 21, card 22, at least one pair of copper brace 23, described card 22 is positioned at the two ends of described copper shell fragment 21, and two in often pair of copper brace copper braces 23 lay respectively at two side positions of described copper shell fragment 21.As shown in Figure 1, described power lug comprises a pair copper brace (only identifying the copper brace on right side in Fig. 1), and this pair copper brace lays respectively at two side positions of described copper shell fragment 21.
Here it should be noted that, the structure centre of the power lug described in the present embodiment is symmetrical, the component of the power lug left and right sides is identical, in order to ensure that accompanying drawing is succinct, the copper shell fragment 21 on the right side of power lug, card 22 and copper brace 23 is only identified, the sequence number that the copper shell fragment on the left side of power lug, card and copper brace identify with reference to right side in Fig. 1.
The inner lower of described rubber-covered shell 1 is provided with the bayonet socket 11 (only identifying the bayonet socket in left side in Fig. 1, the bayonet socket on right side and left side bayonet socket Central Symmetry) for card and described card 22; Formed for placing the placement section need refuting copper core of connecting wires on the downside of described bayonet socket 11 and the inwall of described rubber-covered shell 1; Described copper brace 23 is for refuting the copper core of connecting wires with bayonet socket 11 card with the need being placed on described placement section described in rear contact at described card 22.
Preferably, as shown in Figure 3, described copper brace 23 is pointed dentation, like this described card 22 and bayonet socket 11 block and time, drive copper brace 23 to move down, copper core 0 of connecting wires need be refuted and will be stuck in gap in the middle of pointed tooth, copper brace 23 with need refute copper core 0 of connecting wires and contact.
Here it should be noted that, as shown in Figure 1, the position that the inner lower of described rubber-covered shell 1 corresponds at least one pair of copper brace 23 described is provided with at least one pair of support column 12, and the top of at least one pair of support column 12 described is concordant with the top of described bayonet socket 11; Described bayonet socket 11 is formed for placing the placement section need refuted and connect wires with at least one pair of support column 12 described.
Preferably, in order to make described need refute to connect wires copper core to prevent stable, described bayonet socket 11 is formed for placing the groove need refuting copper core of connecting wires to all corresponding at least one pair of support column 12 described.Like this, described need are refuted copper core of connecting wires and just can be placed directly in this groove, than easy rolling.
Preferably, it is all cylindric for refuting due to current need copper core of connecting wires, therefore described groove is semicircle, described need can be made like this to refute copper core of connecting wires and be more snugly placed in described groove.
Certainly, described placement section also can be that described bayonet socket 11 is formed with the zone line 13 on the downside of the inwall of described rubber-covered shell 1, as shown in Figure 2, this zone line 13 is positioned at inside two described bayonet sockets 11, and the top of described zone line is concordant with the top of described bayonet socket 11; Described zone line 13 is formed for placing the placement section need refuted and connect wires with described bayonet socket 11.Certainly, described zone line 13 also can all correspondingly be formed for placing the groove need refuting copper core of connecting wires on described bayonet socket 11.Described groove is preferably semicircle.
When using above-mentioned power lug, directly two need are refuted to connect wires and insert the two ends of this power lug respectively, described need are refuted to connect wires and is placed into the placement section of this power lug, then instrument is used (to it should be noted that by crimping this power lug two ends here, rubber-covered shell in this power lug is softer flexible), the card 22 in described copper wire connecting portion 2 is made to block with bayonet socket 11 and fix, like this, at least one pair of copper brace 23 on shell fragment will contact with refuting the copper core of connecting wires, and then is communicated with two need and refutes and connect wires.Said wires joint, swift to operate in use, wiring can be completed very soon, and volume is very little, can small space be applied in.
In order to ensure the sealing of power lug, shown in figure 4, described power lug also comprises the first fluid sealant 3; Described first fluid sealant 3 is arranged on the two ends on the downside of described rubber-covered shell 1 inwall, be positioned on the position outside described bayonet socket 11, formed by thin-film package fluid sealant, the top of described first fluid sealant 3 is concordant with the top of described bayonet socket 11, like this, bayonet socket 11 and card 22 block and time, card 22 will puncture the film of the first fluid sealant 3, fluid sealant in first fluid sealant 3 is flowed out solidify, seal the two ends of this power lug.
Or shown in figure 4, described power lug also comprises the second fluid sealant 4; Described second fluid sealant 4 is arranged on the two ends on the upside of described rubber-covered shell 1 inwall, is positioned on the position outside described card 22, is formed by thin-film package fluid sealant, and the top of described second fluid sealant 4 is concordant with the top of described card 22; The top of described bayonet socket 11 is provided with hangnail.Described hangnail can bayonet socket 11 and card 22 block and time puncture the film of the second fluid sealant 4, the outflow of the fluid sealant in the second fluid sealant 4 is solidified, seals the two ends of this power lug.
Certainly, because in the present embodiment, the volume requirement of power lug is less, come to encapsulate this power lug to ensure enough fluid sealants, shown in figure 4, described power lug can comprise the first fluid sealant 3 and the second fluid sealant 4.
When using the power lug shown in Fig. 4, directly two need are refuted to connect wires and insert the two ends of this power lug respectively, described need are refuted to connect wires and is placed into the placement section of this power lug, then use instrument by crimping this power lug two ends, the card 22 in described copper wire connecting portion 2 is made to block with bayonet socket 11 and fix, like this, at least one pair of the copper brace 23 on shell fragment will contact with refuting the copper core of connecting wires, and then is communicated with two need and refutes and connect wires; Meanwhile, the hangnail on card 22 and/or bayonet socket 11 can puncture fluid sealant, fluid sealant is flowed out and solidifies, seal nipple two ends.So just ensure the sealing of this power lug, moisture resistance is better, should not leak electricity.The power lug that the present embodiment provides is applicable to various refuting of hard copper core electric wire and connects, and has wide range of applications.
The above; be only embodiment of the present utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of described claim.
