Abstract
The utility model discloses a low-voltage joint, comprising at least one line pressing jacket and an expansion jacket integrated with the line pressing jacket and used for inserting into a connecting sleeve at the device side, wherein the expansion jacket is coaxially provided with thread holes, the inner diameter of the hole section of the expansion jacket embedded into the insertion part of the connecting sleeve at the device side is less than the large diameter of the corresponding threads, after the completion of mounting, the insertion portion and the connecting sleeve are in conference fit. The utility model provides a low-voltage joint with low connection resistance and easy use.
Description
(1) technical field
The utility model relates to a kind of low-pressure connector device, particularly, relates to a kind of low-pressure connector that is used for low-voltage equipment electric wire or cable connection.
(2) background technology
Mostly known low-pressure connector is O type joint, C type joint, be exactly a terminal for having above-mentioned shape of joint, but the other end is the cover of crimping cable.Such low-pressure connector is mainly used in the crimping connection that equipment end has binding post, the pretightning force of the main pressured tight bolt of this class joint realizes that cable is connected with the reliable of binding post, because it is little to connect area, cause connection resistance excessive, cable connects the energy consumption height, also may be because of the crimping pretightning force is not enough, and cause the cable can't conducting.
The jointing that another kind of low-pressure connector has line ball cover and line pressing bolt based on present equipment end, wherein line pressing bolt is positioned at a side of line ball cover, and cable is penetrated the line ball cover, compresses by line pressing bolt.The low-pressure connector of this structure will be got well than preceding type low pressure tieing convenience, but can destroy connector lug usually because of line pressing bolt, causes actual some contact to connect, and it is higher to connect resistance, is easy to cause connector to be burnt out.
(3) summary of the invention
Therefore, the utility model connects the higher defective of resistance at present low-pressure structure, provides a kind of connection resistance low, easy to use low-pressure connector.
The technical solution adopted in the utility model is:
The utility model low-pressure connector, it comprises at least one line ball cover and overlaps the expansion set that is used to insert equipment end wiring sleeve of one with this line ball, wherein expansion set is coaxial with it is provided with screwed hole, and its hole section internal diameter of insertion section that is used to embed described equipment end wiring sleeve is less than the big footpath of respective threaded, and after finishing assembling, described insertion section and wiring sleeve interference fit.
Above-mentioned low-pressure connector, described screwed hole are blind hole, and have overfolw hole in the hole of its insertion section section, and scribble conductive paste in the section of described hole.Further, described overfolw hole is uniformly distributed on the described insertion section.
Described screwed hole is consistent with the cable patchhole direction of described line ball cover, and described expansion set is connected in line ball cover tail end one side.
Above-mentioned low-pressure connector, described screwed hole comprise the thread segment of porch and corresponding to the unthreaded hole section of described insertion section.
According to the technical solution of the utility model as can be known, this programme has adopted a kind of brand-new connector structure, promptly comes the electrical connection of realization face contact by expansion set, and contact area is big, and it is just little to connect resistance accordingly.In addition, its insertion section be easy to cooperating of described wiring sleeve control, very easy to use.To connect resistance little in addition, and the heat that produces at tie point also compares less, and the possibility that burns out jointing is minimum.
In addition, because corresponding to the connector that has line ball cover and line pressing bolt structure now, annex quantity does not increase, only be to change into the version that expansion set replaces screw in compression, cost does not have what increase.
(4) description of drawings
Fig. 1 is the structural representation of the utility model embodiment low-pressure connector.
Fig. 2 cuts open structural representation for the master of the utility model embodiment low-pressure connector.
Among the figure: 1, line ball cover, 2, expansion set, 3, overfolw hole, 4, screwed hole, 5, thread segment, 6, the insertion section.
(5) embodiment
Specify the utility model below in conjunction with Figure of description:
With reference to the attached Fig. 1 and 2 of explanation, the present embodiment low-pressure connector, it comprises at least one line ball cover 1 and overlaps the expansion set 2 that is used to insert equipment end wiring sleeve of one with this line ball, wherein expansion set is coaxial with it is provided with screwed hole, and its hole section internal diameter of insertion section 6 that is used to embed described equipment end wiring sleeve is less than the big footpath of respective threaded, and after finishing assembling, described insertion section and wiring sleeve interference fit.
Described screwed hole is a blind hole, and has overfolw hole 3 in the hole of its insertion section section, and scribbles conductive paste in the section of described hole.During installation, along with entering of screw, conductive paste overflows by described overfolw hole and enters on the described mating surface that inserts section and described wiring sleeve, has both increased electrical connection properties, can play corrosion-resisting function again, the useful life of increase connector.
Described overfolw hole is uniformly distributed on the described insertion section, to improve the uniformity of smearing of conductive paste.
For the ease of installing, described screwed hole is consistent with the cable patchhole direction of described line ball cover, and described expansion set is connected in line ball cover tail end one side.
Described screwed hole comprises the thread segment 5 of porch and corresponding to the unthreaded hole section of described insertion section, when reducing the length of thread segment, also can be convenient to be provided with the wall thickness of unthreaded hole section, make trip bolt to enter obstacle smaller.
Claims (5)
1. low-pressure connector, it is characterized in that it comprises at least one line ball cover (1) and overlaps the expansion set that is used to insert equipment end wiring sleeve (2) of one with this line ball, wherein expansion set is coaxial with it is provided with screwed hole, and its hole section internal diameter of insertion section (6) that is used to embed described equipment end wiring sleeve is less than the big footpath of respective threaded, and after finishing assembling, described insertion section and wiring sleeve interference fit.
2. low-pressure connector according to claim 1 is characterized in that: described screwed hole is a blind hole, and has overfolw hole (3) in the hole of its insertion section section, and scribbles conductive paste in the section of described hole.
