Utility model content

The purpose of this utility model is to provide a kind of more quick water-proof connector of cable butting.

Above-mentioned technical purpose of the present utility model technical scheme is that：

A kind of water-proof connector, including main body, the main body uniformly offer multiple mounting grooves, the mounting groove around axis Binding post is inside contained, the rear plug for closing multiple mounting grooves is connected with one end of the main body, it is right beyond the Great Wall after described The first entrance hole should be offered in the opening position of mounting groove, the opening position that mounting groove is corresponded on the other end of the main body offers Second entrance hole, the binding post includes interconnecting and one end is right against the first plug division of the first entrance hole and another Rectify the second plug division for the second entrance hole.

By using above-mentioned technical proposal, the inner core eliminated in existing connector sets, inserted main body as wire pair Connection member, simplify the layout of the structure and whole inner member inside connector；Secondly two cables docking when, Only need that the first entrance hole from rear plug and the second entrance hole of main body penetrate respectively by the electric wire in cable, and be inserted into and connect In first plug division and the second plug division at line terminals both ends, you can realize the connection between two cables, eliminate wiring spiral shell The design and operating process of nail, improve agility during cable butting.

Preferably, the binding post includes base portion and the first formed contact is flipped up by base portion both sides Piece and the second contact chip, the first tabletting that first contact chip turns down including one end to the second contact chip side, described second Contact chip includes one end away from the first tabletting and two the second adjacent tablettings turned down to the first contact chip side, and described the One tabletting forms the first plug division with the region that the second contact chip encloses, and two the second tablettings are enclosed with the first contact chip Close the region formed and form the second plug division.

By using above-mentioned technical proposal, the first contact chip and the second contact chip realize the conducting of electric current by base portion, two The electric wire at end can be respectively between the gap between the first tabletting and the second contact chip and the second tabletting and the first contact chip Gap in penetrate, it is possible to realize the conducting of both ends electric wire, operation and its simple, and due to setting two the second tablettings real The purpose of electric wire one-in-and-two-out is showed, has eliminated extra the step of increasing deconcentrator, further improve side during docking Just property.

Preferably, the water-proof connector also includes the off-line block that sliding is connected in the first entrance hole, described de- Line block, which includes one end, can force in the first tabletting and make its one end toward the crushing block away from the lateral movement of the second contact chip one, described to squeeze Cable-through hole is offered in briquetting.

By using above-mentioned technical proposal, electric wire with binding post when being attached, it is necessary to through on crushing block Cable-through hole is attached with binding post again, is easy to operation of taking out stitches while electric wire installation is not influenceed, is needed during taking out stitches Crushing block is pressed, unlock piece is used as by crushing block acts on the first tabletting and bring it about elastic deformation, originally passes through first The electric wire that tabletting is compacted is unlocked, and easily can be passed from threading hole.

Preferably, first contact chip and the second contact chip enclose to form a line chamber, first tabletting and two There is the first importing block and second that side is protruded into line chamber to import block respectively for the end of second tabletting, and described first imports block An introducing port is respectively provided with outside line chamber with the second importing block.

By using above-mentioned technical proposal, the introducing port for importing the setting of block and then being formed outside line chamber can play pair first The guide effect of electric wire is inserted, secondly electric wire increases connecing between electric wire after being inserted into line chamber using the introducing port Contacting surface is accumulated, and improves the compression intensity of electric wire.

Preferably, branch hole, second inlet wire are offered adjacent to the second entrance hole on the end face of the main body The two second importing blocks that hole and the position of branch hole are corresponded respectively in the second tabletting.

By using above-mentioned technical proposal, the setting of branch hole more preferably play separation during electric wire separated time And guide effect.

Preferably, the hole of taking out stitches being connected is offered in second entrance hole and/or branch hole.

By using above-mentioned technical proposal, electric wire is being inserted into the first plug division and the second plug division or, can utilize work Part inserts from hole of taking out stitches and extrudes the first tabletting or the second tabletting is so that both deform, increase and the first contact chip or Gap between the contact chip of person second, and then electric wire can easily be pulled out from the first plug division or the second plug division, Completion is taken out stitches process.

Preferably, kept off in the side wall of first contact chip and the second contact chip to line chamber convex swaging into one Block.

By using above-mentioned technical proposal, behind the first plug division and the insertion of the second plug division, end can abut to electric wire On block, block can improve contact during cable butting as electric-conductor；Secondly the intubating length of electric wire, raising pair can be shortened Rapidity when connecing.

Preferably, to line chamber evagination swaging into a projection on the end face of the base portion, confession is offered in the main body The guide groove that projection slides, the guide groove connect with mounting groove.

By using above-mentioned technical proposal, binding post is used as guiding when being fit into inner core housing, by the use of projection And mark action.

Preferably, second contact chip outwards turns down relative to one end of the second tabletting and forms flange, the master The resigning breach connected with mounting groove is offered on body.

By using above-mentioned technical proposal, the flange to be formed that turned up on the second contact chip can insert from resigning breach, more It is further to play a part of being oriented to and quickly identify installation position.

Preferably, the water-proof connector also includes the adapter sleeve and locking screw being threadedly coupled with the both ends of main body Mother, one end of the adapter sleeve are provided with flexible catch, contain grommet component in the flexible catch, on the adapter sleeve Also screw thread has the packing nut that can collapse flexible catch.

By using above-mentioned technical proposal, cable utilizes packing nut and the spiral shell of adapter sleeve after grommet component passes through Flexible catch is collapsed in line connection, and is applied to by flexible catch on grommet component to realize the holding to cable, improves Installation fixing to cable.
