Abstract
The utility model relates to a cable connector capable of proofing lightning and shielding high current. The inner wall of the opening of the threaded end of a connector plug shell is conical and is matched with the shape of a joint, and a cable clamp holder is connected with the connector plug shell through conical surfaces, so that the contact area is enlarged. When high-current interference is generated on the shielding net of a cable, the high current can flow to the connector plug shell via the cable clamp holder and then flow to the ground to disappear, and thereby the connector cannot be burnt by the high-current interference generated by lightning and the like. A surrounding spring sheet is arranged between a connector socket shell and the connector plug shell and is respectively contacted with the surfaces of the connector socket shell and the connector plug shell, so that the direct contact areas are enlarged, and consequently, the higher the passing current is, the better the effect of shielding the high-current interference can be.
Description
Technical field
The utility model relates to connector, in particular for the connector of cable, and can anti-lightning strike and shielding super-large current.
Background technology
The wire and cable connector of existing band shielding generally comprises four parts: connector body, connector plug, line ball tail cover are provided with the shell fragment that contacts with the cable shielding net in the tail cover, and are to electrically connect between the various piece.Cable enters into connector and is fixed on the line ball tail and puts, shell fragment in the shielding stratum reticulare of cable and the line ball tail cover electrically connects, so, disturbance current on the gauze screen just can flow on the connector plug shell by the shell fragment of line ball tail cover, and the connector plug shell electrically connects with the connector body shell, so, electric current on the gauze screen will flow on the connector body shell, be connected with ground owing to the connector body shell again, electric current on the connector body shell will join with the earth and disappear at last, and the disturbance current conductively-closed that is about to produce on the cable is fallen.Above-mentioned connector only is just to have function of shielding under the situation of little current interference, when having big electric current to pass through on (connector) gauze screen, because the connection contact-making surface area of each parts connector body shell of connector, connector plug shell, line ball tail cover inner shrapnel is less, big electric current (as thunderbolt) can't pass through, cause the connector contact site current overload phenomenon to occur, the huge heat that overload is produced might burn each contact site of (cable) connector.
The utility model content
It is anti-lightning strike and shield the wire and cable connector of big electric current that technical problem to be solved in the utility model provides a kind of energy, can shield the interference of big electric current, and anti-lightning strike.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of energy is anti-lightning strike and shield the wire and cable connector of big electric current, comprises connector body shell, connector plug shell, line ball folder support, is articulated in wire clamp gland, tail-hood on the line ball folder support; Described connector body shell is connected with the connector plug shell, and described connector plug shell is connected with tail-hood; Described line ball folder support is arranged in the tail-hood together with the wire clamp gland; Described line ball folder support comprises junction surface, line ball portion, and described junction surface is frustum type, and the end opening inwall that connector plug shell and line ball folder support join is the conical surface, and agrees with mutually with described junction surface shape.Be connected for the conical surface between line ball folder support and the connector plug shell, contact area increases, cable shielding is online when producing big current interference, big electric current can press from both sides support by line ball and flow on the connector plug shell, and then flow into the earth and disappear, guaranteed that this contact site can not burnt because of the big current interference of generations such as thunderbolt.
As improvement, be provided with between described junction surface and the line ball portion and compress platform, be provided with clamp ring in the described tail-hood, it is described that to compress the platform external diameter bigger than the clamp ring internal diameter in the tail-hood.During the locking of tail-hood and connector plug shell, clamp ring presses and compresses platform, and it is tight more to enter the junction surface and the connector plug housing contacts that make the line ball support.
As improvement, described line ball portion is provided with protuberance, and corresponding protuberance place is provided with depressed part on the wire clamp gland, and described protuberance cooperates with depressed part, and the two also runs through with a rotating shaft.
As improvement, described line ball portion is provided with screw, and described wire clamp gland is provided with screw.By cooperating of screw and screw, can make firm being fixed on the line ball folder support of cable.
As improvement, be provided with the border shell fragment between described connector body shell and the connector plug shell, described border shell fragment respectively with connector body shell and connector plug housing contacts.The border shell fragment increases the contact-making surface area of connector body shell and connector plug shell, and the electric current that can pass through is big more, and the effect that shields big current interference is good more.
The beneficial effect that the utility model is compared with prior art brought is:
Be connected for the conical surface between line ball folder support and the connector plug, contact area increases, cable shielding is online when producing big current interference, big electric current can press from both sides support by line ball and flow on the connector plug shell, and then flow into the earth and disappear, guaranteed that each contact site of connector can not burnt because of the big current interference of generations such as thunderbolt;
The border shell fragment increases the contact-making surface area of connector body shell and connector plug shell, and the electric current that can pass through is big more, and the effect that shields big current interference is good more.
Description of drawings
Fig. 1 is the utility model structure broken away view.
Embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 1, a kind of energy is anti-lightning strike and shield the wire and cable connector of big electric current, comprises connector body shell 1, connector plug shell 2, line ball folder support 3, wire clamp gland 6, tail-hood 4.Described connector body shell 1 directly plugs together with described connector plug shell 2, perhaps relies on bayonet socket to make the two tight connection.Be provided with border shell fragment 5 between the junction of connector body shell 1 and connector plug shell 2, described border shell fragment 5 comprises quoit 51, number of metal shell fragment 52, metal clips 52 directly comes out from quoit 51 bendings, and be evenly distributed on the quoit 51, border shell fragment 5 relies on the elastic force fixed cover of shell fragment on connector plug shell 2, and can be stuck in the interior ring recess 21 on the connector plug shell 2, when connector body shell 1 is connected with connector plug shell 2, border shell fragment 5 respectively with connector body shell 1 on surface 11 contact with interior ring recess 21 on the connector plug shell 2, increase the contact area between the two.Described connector plug outer casing screw end 22 is threaded with tail-hood female end 41, and line ball folder support 3 is arranged in the tail-hood 4 together with wire clamp gland 6.Described line ball folder support 3 comprises junction surface 31, line ball portion 32, described junction surface 31 is frustum type, described connector plug outer casing screw end 22 opening inwalls are the conical surface 23, and agree with mutually with described junction surface 31 shapes, between outer square metre 2 of line ball folder support 3 and the connector plug for the conical surface is connected, the contact area increase.
