Description
Technical field
The present invention relates to a kind of Electric connector, it has a grafting part that constitutes a screw sheel, can divide the locking nut that cooperates the relative grafting part of pegging graft with this Plug Division to screw in one.
Background technology
Be well known that for this connector part and the receptacle portion of pegging graft locks preventing by a locking nut separates mutually unintentionally.For this reason, locking nut is screwed on the external screw thread of the opposite side partly of pegging graft usually, until push up an axial stop structure on the part of pegging graft, and fixing the chucking, make described being threaded to unclamp, described grafting part is by encircling sealing ring or equivalent axial seal by an O shape.
The shortcoming of this known connector is fixing or dismantles the required time of this socket connection, when running into fault, needs promptly to pull down and to change damaged parts.
DE10003924A1 discloses a kind of connector, and it can removably be connected with the receiving unit of a connector by means of a bayonet fittings.For this reason, be provided with the notch that cooperatively interacts on the outer surface of the guide sleeve of connector and receiving unit, it cooperates with the directing pin of relative set being plugged on a time-out, and the rotation guide sleeve just can make described connector peg graft regularly.Because this connected mode is for the mechanical requirement of directing pin and the notch that cooperates with this pin, so be not used in the axial connection of the connector with less connected structure.
A kind of coaxial radio-frequency connectors is disclosed among the DE3022102C1, wherein has a connector part at least for having an externally threaded screw sheel, and, in this connector, one revolves and inserts part and a grafting part that has the joint of a bayonet socket can be outwarded winding, or fixes by means of rotational lock.Certainly owing in this connector, cancelled seal usually, so, peg graft with unload the operation that is connected in slotting power and pull out force be not very big, thereby make and can only bear very little load on the locking nose (Verriegelungsnasen).
DE29618581U1 discloses a kind of Electric connector, and wherein the sleeve part can be fixed on the part of pegging graft by means of a locking nut.This locking nut not only comprises one and is used for having the internal thread that an externally threaded part of pegging graft is connected with one, and the recessed structure (Aussparungen) of given shape, it is used to be connected the grafting part that has export trade (AuBenzapfen), for example a bayonet coupling connector.Shortcoming is that the load that described export trade can be born for the contact engaging and separating force that occurs is very little.Under the situation that use is threaded, can not realize pegging graft rapidly and install, because complete grafting process must be finished by means of screwing locking nut.
EP0431408A2 discloses a kind of Electric connector of bayonet type locking.This connector is to realize like this installing rapidly, and it has a guiding groove, and this groove is used to receive a guiding tendon, and has a very big gradient.Yet this almost constant heavy grade can not satisfy the different requirement of locking aspect.
US6099329 discloses a kind of Electric connector, and screw shell wherein only is made of two parts.Because this screw shell no longer has the cylindrical shape of sealing,, and can not durablely use reliably so this connector is not firm.Plugging and unplugging with revolving force in the grafting process can be easy to the damaged screw sleeve part.
Summary of the invention
For being contained on the machine, on the transducer and the connector that is used for the industrial use on the electronic device of distributing signal or voltage, higher requirement being arranged aspect durability and the sealing.Be proved to be useful by means of being sealed in of sealing ring realization is industrial.For this reason, break down and change thus under the situation of trouble unit, transducer or electronic device at machine, must be with connecting lead promptly separately, so that unload these parts from these devices.It not is the inappreciable time that the present connector that uses always needs when the spiral that unclamps connector connects.At such prior art, plug-in unit of the present invention has adopted a kind of durable fixed form, and it has reduced in the present connector is not inappreciable consuming time, and guaranteed with market on being connected of commonly used connector.
The structure that the present invention proposes is the unique application of a kind of screw thread in this plug connector; it can axially form a kind of sealing of interference fit very nearby from joint edges by being screwed in, and this sealing can be protected bad (rauen) influence in the external world that the contact avoids usually occurring.
Therefore, the present invention proposes a kind of Electric connector, it has a grafting part that constitutes a screw shell, be used to screw in a locking nut, perhaps be used to screw in the fixing housing parts of an electronic instrument, the external screw thread of wherein said screw shell has a no threaded portion that is arranged on the grafting direction at least, on peg graft a locking nut or a housing with this no threaded portion be equal to (
) and during the internal thread that cooperates therewith, can almost completely insert this no threaded portion, and, for the fixing operation of carrying out of screwing has reduced the screw action of half way around to maximum commentaries on classics.This structure also can be used for full thread, thereby can make up with the commercial general standard connector with same size and connected mode.

Embodiment
On screw shell shown in Figure 13, have an external screw thread, but this external screw thread only appears on the regional area 5 of screw shell 3 peripheries.Location by this threaded portion 5 has formed no threaded portion 7,7 ', and this zone can receive the threaded region 6 on the locking nut.In contrast, revolve and insert part 2 and have a locking nut 4 that has internal thread 6, it has the no threaded portion 8,8 ', 8 with respect to the interface position location " and the zone that is threaded 6.
Figure 2 illustrates the perspective view of screw shell 3, this sleeve has the useful annular knurl limit that is used to operate, thereby is convenient to rotary screwing thread sleeve 3, screwed as can be seen from the figure regional 5,5 ', 5 " with and distribute.Although the threaded portion shown in Fig. 25,5 ', 5 " on the periphery of screw shell 3, be asymmetric distribution, also can adopt a kind of form of simple symmetrical distribution.Yet, this asymmetrical form has advantage, that is exactly, in revolving the process of going around, can make a joint only be in a position, shown in Figure 4 when having the seal 14 of very big flexibility when adopting, this fixedly is favourable for connector 1, because pitch is big, almost is that it revolves the whole process of going around so the anglec of rotation of screw shell 3 is increased to.
As can be seen from Figure 3, be equal to screw shell 3, locking nut 4 has a no threaded region 8,8 ', 8 ", this zone is positioned at the regional opposite position that is plugged on two parts.So, the radially-protruding threaded portion 5,5 ', 5 of screw shell 3 " and (its prolongation on the peripheral direction with locking nut 4 on no threaded portion corresponding) slip into mutually; up to as shown in Figure 4, the seal 14 on interface direction X-X defines it and moves mutually.When the threaded portion on the periphery at two elements 5,5 ', 5 ", 6,6 ', 6 " when being symmetrically distributed, on engaged each plug connector, no threaded portion 7,7 ', 7 ", 8,8 ', 8 " place on the identical peripheral position, its size is also identical.Therefore, the scope of screw thread covering is bigger.Particularly, in order to find the interface position of grafting easily by the peripheral direction rotation of annular knurl outer ledge, be provided with external label 17,18, this two mark is preferably the mark that has color, perhaps shown in Fig. 2 and 3, make the plane of no annular knurl, thereby form a tangible visible dots, by making two mark position unanimities, screw shell 3 and locking nut 4 are pegged graft mutually.
Fig. 4 shows the structure after screw shell 3 spins mutually with locking nut 4.At this, two connectors 1 and 2 element and the stop surface 13 and 15 of axially going up alignment thereof be along lip ring 14 of direction of engagement Y extruding, and this sealing ring general encloses for O shape commercial.The part, contact that like this, has just prevented insulation location in plug connector is subjected to disadvantageous ectocine.
A kind of favourable form of implementation of the alignment of no threaded portion has been shown among Fig. 5.Each spiral part rotated easily when the alignment of no threaded portion on the upper surface of screw shell 3 and the locking nut 4 that is equal to made operation.No threaded portion 7,7 ', 7 on the screw shell 3 " or with its locking nut that is equal to 4 in no threaded portion 8,8 ', 8 " integral body align make consistent to the angle of two elements, be angle α, do not have like this, therewith that threaded portion is corresponding a threaded portion 5,5 ', 5 ", 6,6 ', 6 " must have identical angle.It is important in this that position in a circumferential direction, these zones also should be consistent.
Certainly, at no threaded portion 7,7 ', 7 " before and after screw thread must be arranged in the groove (Flucht) of relative screw thread, could guarantee the screw-in of locking nut like this.So,, also can adopt the commercial general connector that has full thread 1,2 for two kinds of inserting mode.To have the connector combination of different connected structures) time, the for example no threaded portion of a symmetry and asymmetrical no threaded portion combination, the performance of this connector is different from another connector, it is very time-consuming usually when for example a kind of commercial connector that has full thread commonly used, this connector threaded portion dock fixedly mutually.
In another unshowned form of implementation, can expect assigning to replace having revolving of a locking nut 4 and inserting part 2 with the fixing housing section on the device, this fixing housing parts has a reception threaded portion that cooperates corresponding to locking nut.If the execution mode of internal thread of a device connecting portion is suitable for the internal thread 6,6 ', 6 according to locking nut 4 of the present invention " condition, then under the situation of the connecting portion on direct employing device, can reduce the fixedly operation time spent of connector 1.
