Description

A kind of multicore rotary connector

Technical field

The utility model is related to the electrical cnnector on a kind of wireless drilling inclinometers, is especially on a kind of rotation of multicore Turn connector.

Background technology

In wireless drilling inclinometers, between mechanical structure be attached with screw thread pair, and electrically between be all It is attached with various connectors, the more commonly used there are two kinds, and one kind is attached with ten core plugs (seat) 100, connects shape Formula is as shown in Figure 1；Another kind is attached with the mode of aviation plug (seat) 200+ spiral cables 300, type of attachment such as Fig. 2 institutes Show.

Regardless of type of attachment, because connector can not rotate in itself, the screw thread in structural member connection procedure When pair is threaded in or out, operation is all inconvenient, and does not note slightly, will result in plug or connected part Damage.In the first connected mode, plug (seat) damage or base end is often caused to break and split, mainly due to termination Frictional force between 400 and matrix 500 is larger, and when termination is rotated, matrix follows rotation, especially in dismounting, due to termination It is dead by mud cavity between, so being easier to damage.In second connected mode, mainly spiral cable 300 is easy Damage, the domestic general heatproof of spiral cable can only achieve 85 DEG C or so, so the well of higher temperature cannot all be used, even entering Mouth cable, due to rotate, so often cable knots, causes breakage.

Utility model content

Based on above-mentioned some problems, the utility model provides a kind of multicore rotary connector, and the connector can freely revolve Then wire influence is not received, will not also destroy wire.

To achieve the above object, the utility model takes following technical scheme：A kind of multicore rotary connector, including plug With socket two parts, the plug includes axial plug body, at least offers one vertically on the outer peripheral face of plug body Cabling channel, wire is equipped with the cabling channel；Axially spaced dead ring and conducting slip ring, institute are arranged with plug body periphery State each wire in cabling channel and correspond to respectively and be welded on a conducting slip ring, the connection of the other end draw plug of wire Onto electrical part；

The socket has axial cavity, and pad, contact and dead ring, spring leaf are provided with the cavity, wherein The dead ring and the axially spaced setting of spring leaf, the wire drawn on self-brazing pad are welded on spring leaf, a wire pair Answer a spring leaf；

After the plug and socket is to inserting, the spring leaf and conducting slip ring contact are conductive.

Further, the quantity of the conducting slip ring and the one-to-one contact of spring leaf, the conducting slip ring and spring leaf is big In equal to number of conductors.

Further, the cabling channel has 3-10 bars, uniform in the outer circumference surface of plug body.

Further, the plug also includes fixing bolt, interior perforating line；Bolt head as axial contact with it is described Contact on socket is conductive.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawings and examples, wherein accompanying drawing constitutes the application one Point, and be used to explain the utility model together with embodiment.

The utility model provides a kind of multicore rotary connector, and as shown in Fig. 3-1,3-2, the connector includes the He of plug 1 The two parts of socket 2, plug 1 has circular, circumferential inner surface, and socket 2 has circular, circumferential outer surface, and plug 1 can be with periphery The rotation of screw thread pair is rotated freely and is inserted into socket 2, and it is very convenient to operate, but simultaneously without prejudice to is conducted between the two, and Can be turned on for multiple spot.The concrete structure of plug 1 and socket 2 is as described below.

As shown in Fig. 4-1,4-2,4-3, the structural member of plug 1 includes plug body 11, connector assembly 12, fixing bolt 13, absolutely Edge ring 14, the several parts of conducting slip ring 15.Plug 1 is axle part, and plug body 11 is docked on connector assembly 12, from plug body 11 Centre bore penetrates fixing bolt 13.Offer at least one cabling channel long 16 vertically on the outer circumference surface of plug body 11, often A wire is connected in individual cabling channel.Cabling channel 16 is general uniform a plurality of in the circumferential, from 3 to 10, as shown in FIG. It is 8.A plurality of cabling channel 16 can wear a plurality of wire, you can as multi-core connector.Wire in plug can be from cabling channel 16 It is connected on electrical part through being passed from the rear end of plug body.Peripheral axially spaced in plug body 11 is arranged with dead ring 14 With conducting slip ring 15, dead ring 14 and conducting slip ring 15 are all smooth annulus, and being enclosed within the periphery of plug body 11 just can be with Cabling channel 16 is hidden in the inside, the quantity of dead ring 14 and conducting slip ring 15 is set according to number of conductors, in cabling channel 16 Each wire correspondence is welded on a conducting slip ring 15, has several wires just to that should have several conducting slip rings, on plug Wire one end is welded on conducting slip ring 15, and the other end passes cabling channel 16 and is connected on electrical part.As its name suggests, conducting slip ring 15 It is electric conductor.

Further, the head that wire is connected to fixing bolt, fixed spiral shell are also passed through in the fixing bolt 13 on plug 1 Bolt head is used as axial contact conductive.

As shown in Fig. 5-1,5-2, the structural member of socket 2 includes outer barrel 21, helmet 22, pad 23, end flange 24, insulation Base 25, contact 26, dead ring 27, spring leaf 28.Outer barrel 21 and the connection of helmet 22 surround socket cavity, and pad 23 is installed on sky Chamber inner bottom part, end flange 24 is connected to outer end, and insulator foot 25 and contact 26 are arranged in cavity, are additionally provided with cavity Dead ring 27 and spring leaf 28.It is also axially spaced to arrange dead ring 27 and spring leaf 28, dead ring 27 and bullet in socket 2 The quantity of reed 28 is set according to the quantity of jack wires, and wire one end is welded on pad 23, and other end correspondence is welded to one On individual spring leaf 28, there are several wires there are several spring leafs.Spring leaf 28 is electric conductor.

Further, as shown in fig. 6, dead ring 27 is to process a recessed platform downwards on a side plane of ring, and And ring both sides external respectively process a ring lack, large and small bolt hole is offered on recessed platform.It is put into recessed platform Spring leaf 28, is fixed with pin.Dead ring as multiple is together in series by big screw, is just formed as dead ring 27 and bullet The space state of reed 28, as shown in fig. 5-1.Dead ring 27 is put into the cavity of socket, lacking position in ring may pass through wire, Piece wire correspondence is welded on a spring leaf 28 just electrically conductive.

Further, spring leaf 28 is in flower-shape, and boss readily accesses wire.

After plug 1 and socket 2 are docked, plug 1 is inserted into the inner ring of spring leaf 28, the conducting slip ring 15 on plug 1 with Spring leaf 28 is contacted, and forms radially conductive.In the axial direction, the contact 27 on socket 2 contacts shape with the fixing bolt 13 on plug 1 Into axial conduction.Due to plug 1 and two parts independence of socket 2, externally only contact a little, respective wire is all inside buried, Have no effect on the rotation of plug or socket；Axial lead is also simply penetrated vertically from core, does not influence equally to rotate.So rotation The plug and socket for turning connector can be rotated freely with the rotation of screw thread pair.

The above, only the utility model preferably specific embodiment, but protection domain of the present utility model is not This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model is disclosed Change or replacement, should all cover within protection domain of the present utility model.
