Technical field

The utility model relates to the arrangements of terminals with busbar described in one kind, for connecting at least one electric conductor.

Background technique

Such arrangements of terminal includes shell and the busbar that can be connected with shell, can be electrically connected on this busbar At least one electric conductor.

Such arrangements of terminal can for example be configured to connecting terminal, especially penetrating terminal.Such connecting terminal can be with other Connecting terminal is for example installed on supporting rail in a manner of rows of each other together, and thus mode, which is realized, can be mounted on switch To provide the arrangement of the terminal of control function, linkage function or insurance function in cabinet or on electrical equipment.

Penetrating terminal usually has there are two tie point, and two can be connected on this tie point for providing between the conductors The electric conductor of electrical connection.Between electric conductor connection by if necessary have big current carrying capacity with electric conductor it Between transmission (big) electric current and the busbar that is for example configured to solid metal part thus realize.

Bolt connecting device is for example configured to for electric conductor to be connected to the attachment device on busbar.By suitable Connecting element, for example in connection lasso form connecting element electric conductor can be installed on such bolt connecting device, from And electric conductor is fixed on busbar by the bolt element of screwing bolts attachment device.

Such arrangements of terminal is for example as known to 10 2,009 057 854 A1 of DE.

There are following demands in such arrangements of terminal, and busbar is fixed in a simple manner in the housing, in addition, together When can firmly hold in the mounted state.Especially busbar should be non-rotatably secured on shell, so that screwing spiral shell Caused torque energy accesses absorption and conduction when tethering the bolt element of connection device, without influencing busbar consolidating on shell It is fixed.

Utility model content

The purpose of the utility model is to provide a kind of for connecting the arrangements of terminal of at least one electric conductor, in energy Realize that busbar is reliably fixed on shell while enough simply installations.

This purpose is realized by the main body of the feature with claim 1.

Arrangements of terminal has locking system as a result, and there is this locking system at least one to be capable of the locking bullet of flexible deformation Spring part can be such that busbar connect with shell locking by this locking spring part.

Therefore the connection of busbar and shell is realized by the locking spring part that there is one or more to be capable of flexible deformation. Therefore, busbar is connected with shell locking, this realizes that busbar simply assembles on shell by grafting, and is installing Under state, under conditions of being made up of the connection of shape cooperation locking system, busbar is securely fixed on shell.

In a kind of design scheme, at least one locking spring part is arranged on shell and in the installation shape of arrangements of terminal It is inserted into the corresponding locking recess on busbar under state.Here, one or more locking spring parts can be set on shell, Such as be molded on shell one-piece and integrally, to be inserted into one on busbar under the installation condition of arrangements of terminal Or in multiple locking recesses.If being provided with multiple locking spring parts on shell, then it can be by locking system multiple The connection that shape between busbar and shell cooperates is established at position, thus by busbar relative to shell reliably, can not turn It is dynamicly fixed.

It is on the contrary, it is contemplated that and it is possible that one or more locking spring parts are set on busbar.In the case, Locking recess is constructed on shell, to establish shape cooperation between busbar and shell under the installation condition of busbar Connection.

Locking system can for example be configured to establish shape between busbar and shell in the side edge of busbar and cooperate Connection.If locking spring part is arranged on shell, under the installation condition of busbar, the insertion of locking spring part converges Flow in the side edge of item in corresponding locking recess and thus establish the connection of shape cooperation between shell and busbar.

In a kind of design scheme, busbar has along the plate by laterally extending with the plane of depth direction expansion Main body.This main body can for example the base shape with rectangle and by side, along depth direction in the two sides of main body The side edge of extension limits.By locking system, main body can be for example at a side edge or two (opposite) sides It ordinatedly connect at edge with hull shape, is fixed on shell so that busbar passes through locking system in the mounted state.

Busbar can be especially established relative to the non-rotatable connection of shell by the locking spring part of locking system, so that Busbar is surrounded perpendicular to depth direction and is non-rotatably fixed perpendicular to lateral short transverse relative to shell.Cause This, busbar cannot be fixed relative to housing into rotation, and therefore relative to shell in its plane, so that especially for example in bolt The torque that the bolt element of attachment device generates when screwing in can be absorbed or be imported in shell on shell.

In a kind of design scheme, at least one locking spring part of locking system preferably along short transverse, it is i.e. vertical In busbar main body plane be it is elastic.Here, locking system for example realizes busbar inserting along direction depth direction Enter installation of the direction on shell, so that busbar be made to be connected with shell, wherein when busbar is installed on shell, lock One or more locking spring part flexible deformations of locking apparatus, that is to say, that deflected perpendicular to the plane of busbar main body.It is converging After flowing item installation, locking spring part is then for example inserted into the correspondence locking recess of busbar and thus by busbar relative to shell Body is fixed.

In order to simplify grafting of the busbar on shell, at least one locking spring part of locking system can be for example with inclining Tiltedly in the contact inclined-plane of depth direction, the deflection of at least one locking spring part is supported when busbar is inserted on shell.Such as At least one locking spring part of fruit is for example arranged on shell, then, busbar then acts at least one locking in grafting It is slided on the contact inclined-plane of spring part and on contact inclined-plane, so that at least one locking spring part is especially perpendicular to busbar master The plane of body deflects.Therefore, under conditions of at least one locking spring part flexible deformation, busbar can be inserted on shell, Wherein, when busbar reaches the insertion position of setting, at least one locking spring part returns to the original state loosened and therefore Locking recess engaging corresponding with busbar.

In a kind of design scheme, at least one locking spring part has locking head and linking arm.Locking head passes through herein Linking arm is connected with the casing section of shell.Such as contact inclined-plane is set on locking head.Locking head is inserted in busbar and shell It is engaged when connecing connected with the locking recess formation on busbar side and therefore establishes shape cooperation between busbar and shell Connection.

At least one locking spring part preferably integrally and is one-piece constructed with the casing section of shell.Correspondingly, Linking arm is connected by an end with casing section, but here, can flexible deformation, enable locking head on linking arm It is enough flexibly to deflect, to be engaged when busbar is connected with shell plug with the locking recess formation on busbar side.

Linking arm for example by-divide along short transverse observation-channel-shaped form of cut or cuts notch and casing section, thus Linking arm can with locking disposed thereon it is first with perpendicular to plane relative to casing section flexible deformation.Along perpendicular to flat The short transverse in face direction is observed, here, notch be molded over the linking arm below linking arm on the side of busbar, from And when busbar is connected with shell plug, at least one locking spring part can be along short transverse elastic deflection.

It in a kind of design scheme, is observed along direction of insertion, locking head is located at linking arm rear.In busbar and shell When plug is connected, busbar be therefore posted by connecting first arm and along linking arm at least one locking spring part towards insert Enter direction promotion.Later, busbar impinges upon on the locking head of linking arm, and thus at least one locking spring part deforms, Busbar is enabled to move through locking head, until locking head is in the state that busbar is connected with shell and on busbar The engaging of locking recess and thus mode establish the connection that shape cooperates between shell and busbar.

It in the state of being connected with shell, observes, converges along the short transverse of the plane perpendicular to busbar main body herein Stream item is for example placed on linking arm, thus bearing of the construction to busbar on shell.Here, on locking head and busbar Locking recess forms engagement, to constitute specific support of the busbar on shell by least one locking spring part.

In a kind of design scheme, locking head is in reverse to direction of insertion in the presence of load with being engaged on for corresponding locking recess In the case where be self-locking.If busbar is in reverse to direction of insertion relative to shell receiving in the state of being connected with shell Load, then, locking head then keeps engaging with corresponding locking recess and especially will not automatically removing from locking recess. Therefore, the load force on busbar not will lead to busbar (undesirably) from shell abjection, and ensure that busbar and loading In the case of fixation on shell.

At least one locking spring part be preferably perpendicular to plane be elasticity and therefore can be in busbar and shell grafting Along the short transverse deflection perpendicular to plane when ground is connected.But here, at least one locking spring part is along transverse to slotting Enter direction and be substantially rigid transverse to the transverse direction of short transverse and cannot deform, to pass through at least one locking bullet Spring part fixing bus-bars are on shell along lateral position.Therefore, pass through at least one locking spring part and busbar locking Engagement, busbar is not only in reverse to direction of insertion and along short transverse but also along laterally relative to case lock.

In a kind of design scheme, locking system tool is used to converge there are two the locking spring part being arranged on shell Flow the connection for establishing that shape cooperates between busbar and shell at the opposite side edge of a main body.Therefore, pass through locking system And its busbar is provided at two side edges of busbar along the locking spring part being transversely spaced apart from each other relative to shell Support, and thus reliably and being able to bear load ground fixing bus-bars relative to shell.

In a kind of design scheme, there is busbar at least one to be used to connect the attachment device of electric conductor.For example, in order to It realizes penetrating terminal, just two attachment devices in bolt connection piece form can be set on busbar, so as to pass through Two electric conductors are connected on busbar by two attachment devices and thus mode is contacted by pass through the penetration type of busbar Part makes it be connected with each other.

Especially there is the bolt that can be screwed in the bolt openings of busbar in the attachment device of bolt connecting device form Element, wherein in order to which conductor to be fixed on busbar, conductor is by especially in the suitable connecting element of connection lasso form It is installed on busbar and is connected by bolt element with busbar.

In a kind of advantageous design scheme, locking system implement to make locking spring part for example on shell with for example What the shape between the corresponding locking recess on busbar cooperated is engaged on bolt element (along screw-in direction) screw-in pair It is self-reinforcing when in the bolt openings answered.Therefore, when bolt element screws in corresponding bolt openings, locking spring part exists Engagement in corresponding locking recess is loaded so that locking spring part holding engaged with locking recess, and thus by In the case where torque load(ing), the connection of shape cooperation will not release easily.

Arrangements of terminal preferably has code device according to another aspect, busbar is only capable of with just a kind of position It is mounted on shell with direction.Such code device is for example with encoder element, this encoder element is for example with the shape of the beam of protrusion Formula is arranged on shell or on busbar, and is inserted under the installation condition of busbar on another element, i.e. busbar Or in the corresponding coding recesses on shell.

Such encoder element for example can be in reverse to direction of insertion protrusion from the rear wall of shell and be in reverse to direction of insertion insertion Along in the correspondence coding recesses on the transverse edge of busbar main body being laterally extended.Here, encoder element and coding recesses Between engagement (along lateral observation) be arranged off-centre, to only in a kind of position and be directed toward upper busbar and could pacify It is attached on shell.

The arrangements of terminal of type described herein is for example designed as connecting terminal, is for example designed as penetrating terminal, and can In conjunction with other arrangements of terminals, so that the sub-assembly of arrangements of terminal is for example assembled on supporting rail.For this purpose, in arrangements of terminal Shell on the fixed device of preferable configuration, shell can fix device by this and be installed on supporting rail, thus in assembled state It is lower shape-ordinatedly to be locked with supporting rail.

In a kind of arrangements of terminal for being designed as penetrating terminal, two are especially arranged on busbar, especially in bolt company Two can be used to be connected to busbar through the conductor of contact by this attachment device by the attachment device of fitting.

Specific embodiment

Fig. 1 shows the arrangements of terminal 1 for being configured to the connecting terminal form of penetrating terminal, this connecting terminal has shell 10, and can be connected with supporting rail 3 with locking by constructing the fixation device 100 in the bottom side of shell 10.

Arrangements of terminal 1 such or different configuration arrangements of terminal can be combined with other, and thus mode is realized Such as the electric component of control function, linkage function or insurance function is provided on the electrical equipment in such as switchgear.

Arrangements of terminal 1 has busbar 11, is mounted in the insertion position 102 in shell 10-in the mounted state- And it is fixedly linked with shell 10.Busbar 11 by conductive solid material constructions and has along by depth in a known manner Spend the main body 110 that the plane E that direction T and transverse direction Q is constituted extends.

There are two in the company with bolt element 130 and the screw connection form of clamping element 131 for the tool of busbar 11 Two conductors 2 can be connected on busbar 11 by connection device 13 by this attachment device.For this purpose, conductor 2 can be filled by side Enter in shell 10, thus by the connecting element 210 on the conducting wire core wire 21 that conductor 2 is wrapped up by wire sheath 20 respectively with connection The correspondence bolt element 130 of device 13 cooperates and is clamped on busbar 11 by clamping element 131, is such as directed in Fig. 1 As shown in (there are two conducting wire core wires 21) conductor 2.

The pin 132 in opening 113 that the clamping element 131 of attachment device 13 passes through busbar 11 guides and passes through bullet Spring element 133 and 11 elasticity of busbar pre-tighten, so that after unclamping corresponding bolt element 130, clamping element 131 and spiral shell Bolt element 130 is mobile and lifts from busbar 11, as in Fig. 1 for as shown in right side attachment device 13.

In order to which conductor 2 to be clamped on busbar 11, the bolt element 130 of corresponding attachment device 13 is screwed in busbar 11 In correspondence bolt openings 111 in main body 110, thus makes clamping element 131 mobile towards busbar 11 and thereby will be in connection The connecting element 210 and busbar 11 of lasso form clamp.

Fig. 2 to 12, which is shown, to be connected with (Fig. 2) of conductor, is not connected with (scheming for conductor 2 under 13 releasing orientation of attachment device 3) and in the state that attachment device 13 tenses but other views of (Figure 10) arrangements of terminal 1 of not connected conductor 2.In shell One conductor 2 can be installed respectively on every side of body 10 and be connected with the device 13 that is correspondingly connected on busbar 11, thus by This mode is realized between the conductor 2 by two sides connection terminal device 1 through connection.

In order to touch the bolt element 130 of attachment device 13, the top surface of shell 10 is on the side away from fixed device 100 Construction opening 101 can for example touch the bolt element 130 of attachment device 13 by this opening by screwdriver.

Such as particularly by combining observation Fig. 7 and Fig. 8 as it can be seen that busbar 11 can be as preassembled component together with being arranged in Attachment device 13 thereon is inserted into the corresponding insertion position 102 on shell 10 along direction of insertion A, and in insert state Under (Fig. 8) be shape-ordinatedly connected by 12 locking of locking system and thereby with shell 10.There are two collection for the tool of locking system 12 At ground molding locking spring part 120 on the housing 10, be configured for insertion into 110 two sides of main body of busbar 11, along In the correspondence locking recess 121 in side edge 112 that depth direction T extends, and thus busbar 11 is fixed on shell by mode In insertion position 102 on body 10.

The height direction H flexible deformation that locking spring part 120 can extend especially along the plane E perpendicular to main body 110. Such as by the enlarged drawing in Fig. 9 as it can be seen that locking spring part 120 is respectively provided with favours depth direction T and favour short transverse The contact inclined-plane 124 of H, busbar 11 along direction of insertion A when being inserted into insertion position 102 by respective side edge 112 Front edge section 114 touches this contact inclined-plane, and thus corresponding locking spring part 120 is flexibly pressed down against, directly To edge section 114, by locking spring part 120, simultaneously therefore locking spring part 120 can be with the locking recess in side edge 112 121 engagings, such as illustratively combine Fig. 4 from Fig. 9.

In the mounted state, busbar 11 is in reverse to direction of insertion A and shape-ordinatedly keeps on the housing 10 and therefore solid It is scheduled on and (passes through the restriction of the corresponding wall portion section of shell 10 up and down along height direction H) in insertion position 102.

Fig. 5 shows the individual view of shell 10, and Fig. 6 shows the individual view of busbar 11.Locking recess 121 From corresponding side edge in the side edge 112 that the two sides of 11 main body 110 of busbar are molded over adjacent main body 110 and as recess 112 extend into main body 110.In the mounted state (for example, see Fig. 4), the locking spring part 120 of shell 10 is embedded in locking In recess 121, and therefore busbar 11 is shape-ordinatedly fixed on the housing 10.

In addition, busbar 11 also has the bolt openings of the bolt element 130 for attachment device 13 as seen from Figure 6 111 and the pin 132 as the clamping element 131 for attachment device 13 guide opening opening 113.

Engagement of the locking spring part 120 in corresponding locking recess 121 is self-reinforcing, so that busbar 11 can not be easily Ground can not be in reverse to direction of insertion A from insertion position under conditions of (intentionally) for example releases locking using tool anyway It sets in 102 and unclamps.Such as by Figure 11 and 12 as it can be seen that when the bolt element 130 of attachment device 13 is tightened along screw-in direction D, This for example causes to generate the torque along screw-in direction D on busbar 11, so that side edge shown in right side in figs. 11 and 12 Edge section 114 on 112 is corresponding on corresponding locking spring part 120 by abutment face 123 along screw-in direction D The formation of abutment face 122 reclines.Locking spring part 120 (especially along height direction H) presses to locking recess 121 as a result, thus anti- Only the locking in load conditions between locking spring part 120 and corresponding locking recess 121 automatically releases.Therefore, especially Torque loads when screwing in the bolt element 130 of attachment device 13 not will lead to busbar 11 undesirably from shell 10 It unclamps.

Figure 13 shows what locking recess 121 corresponding with the main body 110 for being molded over busbar 11 engaged to amplify Locking spring part 120.Locking spring part 120 have locking head 125, on this locking head by favour depth direction T and The inclined-plane formation of contact inclined-plane 124 of height direction H is favoured, and under the connection status of busbar 11, this locking head and remittance The correspondence locking recess 121 for flowing 11 side of item engages, and therefore establishes the connection that shape cooperates between shell 10 and busbar 11.

Locking head 125 is molded on an end of linking arm 126, by this linking arm by locking head 125 and shell 10 Casing section 103 be connected.Here, linking arm 126 and casing section 103 are integrally formed and in separate locking head 125 It is connected on end 127 with casing section 103.

Locking spring part 120 can be inclined relative to 103 elasticity of casing section along height direction H substantially about end 127 Turn.Here, linking arm 126 by slit-shaped, along the molding notch of depth direction T 128 with casing section 103 (along height Spend direction H observation) segmentation, so that locking spring part 120 is by its linking arm 126 and molding locking head 125 on the connecting arm It can be along height direction H relative to 103 elastic deflection of casing section.

When busbar 11 is connected with shell 10, i.e., busbar 11 is plugged on shell 10 along direction of insertion E When, busbar 11 collides and by along direction of insertion E forward section 114 and locking head 125 in each locking spring part It is slided on contact inclined-plane 124 on 120 locking head 125, and thus keeping locking spring part 120 downward along height direction H Deflection, therefore, section 114 move through locking head 125, and final, the locking recess corresponding with busbar 11 of locking head 125 121 engagings.In connected state, by the locking spring part 120 in 11 two sides of busbar to establish busbar 11 and shell The connection of shape cooperation between 10.By constructing locking spring part 120 substantially rigidly not flexibly along lateral Q, Here, busbar 11 keeps the relative position with shell 10 also along lateral Q by locking spring part 120.

It is observed along direction of insertion E, after the locking head 125 of each locking spring part 120 is located at corresponding linking arm 126 Side, so that busbar 11 reclines with the formation of linking arm 126 first and then slides on locking head 125.In connected state, even It connects arm 26 and constitutes the bearing for being used for busbar 11, so that the locking spring part 120 by 11 two sides of busbar is also defined in shell Along the pedestal of the busbar of height direction H 11 on body 10, such as seen from Figure 13.

In connected state, on locking head 125, direction is being molded between locking head 125 and busbar 11, especially Exist between the abutment face 122 of the section 114 of busbar 11 from locking.If as shown in Figure 14, busbar 11 is in reverse to slotting Enter load force F of the E receiving in direction relative to shell 10, section 114 then sticks in abutment face 122 and causes Lock spring part The load of the torque direction M in the direction along the engagement between enhancing locking head 125 and corresponding locking recess 121 on 120.Cause This, the load that direction of insertion E is in reverse on busbar 11 will not easily result between locking spring part 120 and busbar 11 The release of engagement, but in load conditions, locking head 125 squeezes and enhances ground and engage with corresponding locking recess 121.

Such load force F can for example occur when screwing in the bolt element 130 of attachment device 13, it is also possible in Xiang Huiliu Item 11 occurs when applying other power.

In arrangements of terminal 1, guarantee that 11 position of busbar is properly mounted on shell 10 by code device 14.Coding Device 14 is pacified by constituting in the encoder element 140 of the beam-like protrusion form on the wall at 10 back side of shell in busbar 11 The correspondence coding recesses being inserted into the case where installing on the transverse edge 115 that 11 main body 110 of busbar extends along lateral Q In 141, such as from Fig. 4 and 11.Because of the coding recesses on encoder element 140 and busbar 11 on shell 10 141 prejudicially arrange on insertion position 102 (along lateral Q observation), so, busbar 11 can only be just a position Be inserted on direction in insertion position 102, thus support busbar 11 on the housing 10 position and be directed toward correctly installation.

Design based on the utility model is not limited to previous embodiment, and in principle also can be with totally different type of side Formula is implemented.

Arrangements of terminal can also be particularly by the terminal different from penetrating terminal shown here, being used only as exemplary illustration Construction.

Therefore, especially there may also be more than two or less than two attachment devices, this attachment devices on busbar It can also be not configured to be bolted in principle.
