The present invention relates to a kind of for protecting electrical network avoid overvoltage or cross the insertable unit equipment of stream, it can be inserted into the connector module on plant bottom case with plant bottom case with at least one.Here, plant bottom case has the base house of the approximate U shape with the recess for accommodating connector module, for the binding post of conductor of electrical network to be protected and the plug contacts that is connected with binding post.Connector module has inner housing, hood-shaped shell body, the protection element being arranged in inner housing and the connection plug contacts corresponding with plug contacts; wherein, hood-shaped shell body can limited between the position and the position on the second top of the first bottom relative to inner housing be arranged movably.
Background technology
For the safety in operation of electronic equipment, machinery and equipment, continual and steady energy supply particular importance.In order to prevent the stopping or in order to keep electrical network or to be connected to the damage risk of customer at electrical network the least of such as facility or facilities section, it is necessary to prevent electrical network or customer due to overvoltage or persistently occur cross stream, i.e. overcurrent or the damage of short circuit current.For this; use overvoltage protection device and equipment protection switch; it derives the overvoltage of transient state or selectively cuts off the current loop of fault when overvoltage or overload or short circuit, thus prevents the damage of the equipment coupled and make other facilities section maintenance function as much as possible effective.
Not only overvoltage protection device and also equipment protection switch be the most usually configured to the insertable unit equipment with the plant bottom case as lower component and the connector module as upper-part.Within the scope of this invention, insertable unit equipment is possible not only to be overvoltage protection device and can be equipment protection switch, and unrelated with the following overvoltage protection device mainly as the explanation of insertable unit equipment.
In known overvoltage protection device, such as, may be mounted at the plant bottom case on bearing track for being connected to electric lead.In order to install this conductor L1 that such as should protect and guide mutually, the overvoltage protection device of L2, L3 and zero line N and the most also protection ground wire PE, at plant bottom case, it is provided with the corresponding binding post for single conductor.In known overvoltage protection device, plant bottom case is configured to approximate U shape, wherein, is disposed with and is disposed with the binding post for ground wire for phase conductor and the binding post of neutral conductor at another commissural flange lower limb at lower limb.The base house of plant bottom case has recess, and its size matches with the outside dimension of connector module so that connector module can be inserted in this recess.
The connector module of the protection element in order to make plant bottom case simply and be wherein disposed with reality mechanically and electricly contacts; plant bottom case has the plug and socket being connected with binding post and the latch corresponding with connector module so that connector module can be inserted on plant bottom case.The plugability of the over-voltage protection element by being arranged in connector module; there is following probability; i.e. in failure condition or in the case of correction or maintenance work, in the case of need not disconnecting the conductor being connected at the binding post of plant bottom case, change connector module.
In fault or overload situations, can flow through impact or short circuit current momently, it exceedes the rated current several times of electrical network.So, owing to high short circuit current causes strong magnetive attraction, thus over-voltage protection element can be extruded from equipment lower component.Being also applied for accordingly during performance review, wherein, utilize pulse current to load overvoltage protection device, the amplitude of pulse current can exceed the amplitude of short circuit current.
Therefore, risk is to make connector module eject from plant bottom case or lift after performance review and in failure condition or overload situations present in the known overvoltage protection device.Additionally, in the case of strong vibration, it is possible to cause the connector between plant bottom case with connector module to be connected and unclamp, thus no longer can reliably ensure normally electrically connecting of connector module.Although this can thus prevent, i.e. plug and socket and latch structure becomes to make to exist between plug and socket and latch the power also can strengthened by tectonic thickening portion at latch or form fit in the state of connector, but thus connector module can only be inserted in plant bottom case with relatively high power consumption, and can only pull out from plant bottom case with higher power consumption when hope is changed.
By the known a kind of insertable unit equipment illustrated with the beginning of the form of overvoltage protection device of file DE 10 2,008 021 210 B4, wherein, insertable over-voltage protection element has one or two spring element as locking element.When shell body is positioned in the position of its underpart, the free end of spring element can be pressed off each other by means of the chock as operating element being arranged at hood-shaped shell body, so that in the guiding flank that the free end power wedge structure ordinatedly of spring element is at plant bottom case.If insertable over-voltage protection element should be changed; shell body then must be made to be raised to from the position of its underpart in the position on its top; thus; the end of controls also moves upward; thus a spring element or two spring elements can be made to rebound in its initial position; thus, the connection guiding the power between flank to coordinate of the free end at spring element and plant bottom case has been unclamped.
Also by the known a kind of overvoltage protection device being configured to insertable unit equipment of file DE 10 2,008 017 423 A1.In this overvoltage protection device, the connector module with over-voltage protection element can be inserted in plant bottom case and can be locked at wherein in the state inserted.Here, realize connector module locking in plant bottom case by means of the lock pin that rotates in of the limit lower limb being bearing in plant bottom case, rotate lock pin and there is the tongue of extension.After in the receiving portion that connector module inserts plant bottom case, connector module can thus be locked in its position, i.e. makes rotation lock pin rotate by means of instrument, and wherein, the tongue rotating lock pin is joined in connector module in the groove of correspondence.If connector module should be changed, then rotation lock pin must be made again to rotate, so that its tongue moves out and swing in the limit lower limb of plant bottom case in corresponding groove or hole from the groove connector module.Connector module this locking type in plant bottom case is had the drawback that, for the locking in plant bottom case and unblock connector module, it is necessary to make rotation lock pin rotate, it means that additional installation step.
Summary of the invention
Therefore, present invention aim at providing the insertable unit equipment of beginning explanation for use, wherein, plant bottom case and connector module construct as simply as possible, but simultaneously for can the most simply and cosily perform the locking of connector module and unblock and replacing for user.
In the case of the insertable unit equipment with the beginning explanation of the feature described in claim 1, this purpose thus realizes, i.e. arrange at least one kayser acted between plant bottom case and the inner housing of connector module to be connected, wherein, this kayser connects and has at least one with the elastic latch arm of kayser nose and kayser recess or kayser protuberance.In addition, at least one window portion is constructed at least one side of the shell body of connector module, it acts as so that latch arm does not deflects in the position of the first bottom of shell body with latch arm jointly, thus make connector module be fastened in recess by kayser in the state that connector module is fully-inserted, and on the contrary in the position on the second top of shell body, make latch arm overcome its spring force to deflect, thus, cancel kayser to connect, thus connector module can be pulled out simply from plant bottom case.
By making the kayser between plant bottom case with connector module be connected by one side, with the latch arm of kayser nose and on the other hand kayser recess or kayser protuberance form, make kayser connect particularly simple to construct, wherein, additional component can be saved in particular because not only elastic latch arm and kayser recess or kayser protuberance can directly realizations at the base house of plant bottom case or at the inner housing of connector module.By constructing at least one window portion at least one side of the shell body of connector module, can the most thus cancel or unclamp kayser to connect, shell body is i.e. made to move from the position of its first bottom or be raised to the position on its second top, this causes latch arm to deflect, thus kayser nose no longer engages with kayser recess or kayser protuberance.By lifting or pull the shell body of connector module, unclamp kayser the most in the first step and connect, thus afterwards (directly next to) by continuing to lift or pull shell body that connector module can be made to take off from plant bottom case or pulling out from recess.
There are two kinds of probabilities, the i.e. element which place arranges or structure kayser connects in two components (plant bottom case or connector module) in principle, say, that on the one hand latch arm and another aspect kayser recess or kayser protuberance.Here, the latch arm with its kayser nose is arranged and configured so that kayser nose will not hinder connector module plugging to plant bottom case due to the elastic performance of latch arm in both cases, say, that the insertion in connector module to recess.Thus plugging in the case of connector module, making latch arm deflect slightly, thus in the case of there is no bigger power consumption, connector module can inserted in recess.To this end, be configured with corresponding free space on the side back to connector module of latch arm, latch arm is deflectable in this free space.
The first main form of implementation according to the present invention, at least one kayser recessed configuration is in the wall of at least one restriction recess of plant bottom case, and the latch arm with at least one elasticity of the kayser nose corresponding with kayser recess constructs at the inner housing of connector module.Here, relative to the window portion in the side of shell body, kayser nose is arranged so that kayser nose can be stretched out by window portion in the position of the first bottom of shell body.So, in the state in the recess of the fully-inserted plant bottom case of connector module, kayser nose snaps in the kayser recess in the wall of plant bottom case, so that connector module card is locked in plant bottom case.On the contrary, in the position on the second top of shell body, latch arm is deflected by the lower limb in window portion or the wall below window portion that abuts against of shell body, thus kayser nose no longer stretches in the kayser recess in the wall of plant bottom case, thus cancels kayser and connects.
In the enforcement flexible program described above of the unit equipment according to the present invention, at shell body, catch connector module by user and it is pulled out from the recess plant bottom case, the connector module that kayser Connection Card is locked in plant bottom case can be pulled through the most simply from recess.At this, first shell body limitedly lifting relative to inner housing is realized, this causes, and first the kayser nose that the window portion being passed through in shell body stretches out is pressed inwardly from the wall below window portion that abuts against of the lower limb in window portion or shell body, and this causes the deflection of latch arm.The deflection of latch arm or kayser nose causes at this, and kayser nose no longer stretches in the kayser recess in the wall of plant bottom case, thus the kayser between kayser nose with kayser recess is connected and unclamps.Owing to shell body is arranged to only may move limited distance relative to inner housing, further pulling at shell body causes, and the connection plug contacts of present connector module is drawn out from the plug contacts of plant bottom case and thus connector module is pulled out on the whole from plant bottom case.Unclamping that kayser connects realizes from there through single handle with connector module pull-out from the recess of plant bottom case, is i.e. simply pulled at shell body by connector module or is lifted realization.
Below having elaborated, kayser connects latch arm and at least one kayser recess with at least one elasticity.Preferably, each at least one kayser recess of structure in the wall relative to each other of two restriction recesses of plant bottom case.The most correspondingly, the inner housing of connector module respectively has at least one latch arm at two sides relative to each other, and constructs at least one window portion in two sides of shell body the most respectively.Thereby it is ensured that connector module reliable locking in the recess of plant bottom case, connect because being respectively configured with a kayser at two relative sides.
In order to connector module being hindered to the insertion in the recess in plant bottom case by structure latch arm, the kayser nose of latch arm preferably has rake, and it rises on the contrary with the direction of insertion in connector module to plant bottom case.Thus, it is therefore prevented that insert the bending of kayser nose in the case of in recess at connector module or hook, and simplify latch arm rebounding when inserting.
According to the design that another is favourable, the kayser nose of latch arm has card locking face, and the kayser recess in the wall of plant bottom case has the locking face corresponding with kayser face, and wherein, locking face is roughly parallel to the base surface of recess and stretches.Thus, the kayser nose preventing latch arm is undesirably shown from kayser recess, even if thus when fault or overload situations occur strong electromagnetic force (by its with plug in opposite direction the power pointed to and load connector module) time also ensure that the connector module reliable locking in plant bottom case.
In order to simplify desired the unclamping of kayser connection, another favourable design according to the present invention is arranged to, the card locking face of kayser nose stretches with an angle in the locking face relative to kayser recess, and wherein, card locking face rises from latch arm towards the free end of kayser nose.By the card locking face slightly askew stretched, simplify shell body kayser nose showing from kayser recess in the case of the position of the first bottom is raised to the position on the second top.
According to the second main form of implementation of the unit equipment according to the present invention, the latch arm structure of at least one elasticity is in the wall of at least one restriction recess of plant bottom case, and wherein, in addition at least one kayser nose, latch arm also has unblock protuberance.Owing in this flexible program, latch arm constructs at plant bottom case, the kayser protuberance corresponding with kayser nose constructs now at the inner housing of connector module.Additionally, at least one side of the shell body of connector module, be additional to unblock window portion corresponding to protuberance and be also configured with at least one hole at least one kayser nose.
In the state in recess in connector module is fully inserted to the base house of plant bottom case, at this, the locking between connector module and plant bottom case thus realizes, i.e. unlock protuberance and enter in window portion and in kayser nose entrance hole in shell body, wherein, kayser nose and the kayser protuberance at the inner housing of connector module connect common effect as kayser.Therefore, the connector module unexpected extrusion from the recess plant bottom case, i.e. kayser protuberance (and thus inner housing is overall) at inner housing is thus prevented to be fixed in its position by the kayser nose of latch arm.On the contrary, in the position on the second top of shell body, unlock in the window portion that protuberance is no longer in shell body, so that latch arm is deflected by the lower limb in window portion or the wall below window portion that abuts against of shell body, this causes, and kayser nose does not stretch into and is connected common effect as kayser in the hole in shell body and the most no longer with the kayser protuberance at inner housing.
Thus, in this second enforcement flexible program, shell body lifting or pulling from the position of its first bottom to the position on its second top also causes latch arm to deflect, this causes the kayser between kayser nose with kayser protuberance to be connected being cancelled, then thus connector module can be pulled out from the recess the base house of plant bottom case.
As above also already in connection with as the first enforcement flexible program elaboration of the unit equipment according to the present invention, implement in flexible program second, on the both sides of connector module or on the both sides of recess, the most also construct lock part.Preferably, thus in the wall relative to each other of two restriction recesses of plant bottom case, at least one latch arm is respectively constructed.So, these external two sides relative to each other of inner housing respectively have at least one kayser protuberance and in two sides of shell body, also construct at least one window portion each and at least one hole.
In order to implement flexible program will not hinder due to structure latch arm the most as far as possible connector module to the insertion in the recess in the base house of plant bottom case second of the insertable unit equipment according to the present invention, it is preferably set to, kayser nose has rake, but this rake rises on the direction of the base surface of recess now.Inserting the deflection of latch arm in the case of connector module here, structure rake at kayser nose also simplify and thereby simplify connector module to the insertion in recess.
According to another preferred design, at least one and opens wide downwards in the lower edge of shell body for the hole of kayser nose structure.In this design of unit equipment, structure kayser protuberance at inner housing can be formed by the bottom of inner housing simply, and shell body is placed on bottom this in the position of its first bottom.Opening wide downwards by being used in the hole of kayser nose, shell body can be brought in the position on its second top without problems from the position of its first bottom, and is not herein limited by the obstruction of kayser nose.

Detailed description of the invention
Fig. 1 to 6 shows that this unit equipment is made up of plant bottom case 1 and the connector module 2 can being inserted on plant bottom case 1 for protecting electrical network avoid overvoltage or cross the first embodiment of the insertable unit equipment flowed.The second embodiment of insertable unit equipment according to the present invention is shown in Fig. 7 is to 11.
Common in the two embodiment at this, the plant bottom case 1 that illustrates independently in Fig. 4 and 8 has cocker and is locked into the base house 3 of approximate U shape on bearing track, with the recess 4 for accommodating connector module 2.Additionally, be disposed with the binding post 5 of the conductor for electrical network to be protected in the limit lower limb of plant bottom case 1, wherein, in the embodiment being shown here at, binding post 5 is bolt binding post.Obviously, it is possible to use other type of binding post, such as tension spring binding post, direct spring connecting terminal or helix torsion spring binding post or cut clip binding post.Finally, there also is provided multiple plug contacts 6 being connected with binding post 5 in plant bottom case 1 under recess 4, it is configured to plug and socket in this case.
The connector module 2 illustrated in Figure 5 and independently has inner housing 7 and a hood-shaped shell body 8, and wherein, shell body 8 can be relative to inner housing 7 first, move between the position (Fig. 1) of bottom and the position (Fig. 2) on the second top.Being disposed with protection element, in particular overvoltage arrester, such as spark gap or rheostat in inner housing 7, it electrically connects with the plug contacts 9 that couples with bayonet fashion, and this connection plug contacts 9 may be inserted in plug contacts 6 corresponding in plant bottom case 1.Except assembling is simple, also achieved the connector module 2 changing fault simply by the plugability of connector module 2.To this end, connector module 2 can be extracted simply from plant bottom case 1, exactly pull-out from recess 4, without being joined in assembling.
In order to ensure connector module 2 reliably fixing in plant bottom case 1, at plant bottom case 1, construct at least one kayser between its base house 3 and inner housing 7 of connector module 2 in particular and be connected, this kayser connects by with kayser nose 11, the elastic latch arm 10 of 11', 10' and kayser recess 12 or kayser protuberance 13 form.Connect in order to simply and this kayser can be unclamped by user in the case of not having auxiliary tools or additional installation step when connector module 2 desirably should be extracted from plant bottom case 1, difference tectonic window portion 15,15' in two sides 14 of shell body 8.By means of window portion 15,15' and by means of shell body 8 relative to the limited mobility of inner housing 7, can the most thus unclamp kayser and connect, i.e. make shell body 8 move to the position on the second top from the position of the first bottom.Here, so make latch arm 10,10' deflects, i.e. kayser nose 11, and 11' no longer engages with corresponding kayser recess 12 or corresponding kayser protuberance 13.
In the first embodiment according to the insertable unit equipment according to the present invention of Fig. 1 to 6, the wall 16 of two recesses being limited in plant bottom case 14 constructs two kayser recesses 12 respectively, such as can be as seen from Figure 4.Correspondingly, inner housing 7 respectively has two latch arm 10 at two side, and its kayser nose 11 forms kayser respectively and connects with corresponding kayser recess 12.Additionally, construct two window portions 15 in two sides 14 of shell body 8 respectively, the kayser nose 11 of latch arm 10 can be stretched out by window portion 15, and this can find out in particular in Figure 5.
Fig. 1 shows the connector module 2 in plant bottom case 1 in the fully-inserted state with kayser, wherein, in the overview diagram according to Fig. 1 a, a part for base house 3 and adjacent the part also eliminating shell body 8 is eliminated, in order to can be seen that the kayser between plant bottom case 1 and connector module 2 at the limit lower limb in the left side of plant bottom case 1.Here, can find out from the enlarged drawing according to Fig. 1 b in particular, kayser nose 11 extends through the window portion 15 in the side 14 of shell body 8 and stretches in the kayser recess 12 in the relative wall 16 of the recess 4 of base house 3.Here, shell body 8 is positioned in the position of its first bottom.If shell body 8 is taken to the position on its second top from the position of the first, bottom, then this causes, kayser nose 11 is deflected by the lower limb 17 in window portion 15 and is guided from the window portion 15 the side 14 of shell body 8, thus, latch arm 10 is made to deflect inward, thus finally kayser nose 11 no longer stretches in the kayser recess 12 in wall 16, such as this figure 2 illustrates.
Therefore, the kayser between plant bottom case 1 with connector module 2 is connected and unclamps the most in a straightforward manner, i.e. user somewhat (in opposite direction with plugging) lifts shell body 8.Owing to the most automatically having unclamped kayser connection, can extract connector module 2 from the recess 4 plant bottom case 1 simply in the case of not having large force consumption now, such as this figure 3 illustrates.Thus, by opposite direction simply pulling on shell body 8 extracting on direction, that is with plugging, it is achieved between plant bottom case 1 and connector module 2, kayser unclamps and connector module 2 extracting at plant bottom case 1.For unlocking or unclamping kayser, it is not necessary to additional unlocked step, thus may utilize and extract unclamping of Motor execution kayser and taking off or extracting of connector module 2.
In order to hinder connector module 2 plugging to plant bottom case 1 by the kayser nose 11 at latch arm 10, kayser nose 11 has rake 18, and it rises on the contrary with the direction of insertion in connector module 2 to plant bottom case 1.In the case of in the recess 4 being inserted in base house 3 by connector module 2, elastic latch arm 10 deflects, until connector module 2 is fully inserted in recess 4 by limiting the wall 16 of recess 4.In this position, window portion 15 and kayser recess 12 are oppositely arranged in the side 14 of shell body 8, so that kayser nose 11 can be snapped in kayser recess 12 by window portion 15.
The connector module 2 unexpected extrusion from plant bottom case 1 or unclamp thus prevents, and i.e. makes the kayser nose 11 of latch arm 10 have card locking face 19, and the locking face 20 that card locking face 19 is corresponding with kayser recess 12 acts on jointly.Here, the base surface 21 that locking face 20 is roughly parallel to recess 4 stretches, thus kayser nose 11 is prevented undesirably to show from kayser recess 12.Additionally, can be seen that from Fig. 1 b, the card locking face 19 of kayser nose 11 stretches with the angle relative to locking face 20, and wherein, card locking face 19 rises from latch arm 10 to the free end of kayser nose 11.The orientation of the card locking face 19 of kayser nose 11 prevents the free end causing kayser nose 11 when undesirably unclamping locking to bend at the locking face 20 of kayser recess 12.
In second embodiment of the insertable unit equipment according to the present invention shown in Fig. 7 to 11, elastic latch arm 10' constructs in two walls 16 limiting recess 4 of plant bottom case 1 respectively.Here, there are two kayser nose 11' and the unblock protuberance 22 being arranged between the two kayser nose 11' according to latch arm 10' of Fig. 8.In this enforcement flexible program, latch arm 10' constructs at plant bottom case 1, and the kayser protuberance 13 corresponding with kayser nose 11' constructs now at two relative sides of inner housing 7.
As can find out from Fig. 9 a and 9b in particular, in two sides 14 of shell body 8, in addition to the window portion 15' corresponding with unlocking protuberance 22, it is also configured with two holes 23 corresponding for kayser nose 11' with two.Here, hole 23 is arranged in the lower edge of shell body 8 and opens wide downwards, so that hole 23 limits by constructing the kayser protuberance 13 at inner housing 7, such as this can learn in particular from the amplification local according to Fig. 9 b.Here, kayser protuberance 13 is directly formed by the bottom of inner housing 7, shell body 8 is placed on bottom this in the position of its first bottom.Two kayser protuberances 13 (because it by the bottom of inner housing 7 formed) coefficient with in two kayser nose 11' is interconnected to single type the most respectively.
Two diagrams according to Figure 10 a and 10b respectively illustrate the local of the unit equipment in the state of kayser and in the state of non-kayser, in the state of kayser, shell body 8 is positioned in the position of its first bottom, and in the state of non-kayser, shell body 8 is positioned in the position on its second top.Figure 10 a and 10b there is shown herein latch arm 10' or kayser nose 11' relative to hole 23 or the corresponding position of kayser protuberance 13.Figure 11 a and 11b shows latch arm 10' on the contrary or unlocks the protuberance 23 relevant position relative to the window portion 15' in shell body 8.
Illustrating in the position of kayser in figure loa, kayser nose 11' stretches in the hole 23 in shell body 8, thus kayser nose 11'' and the kayser protuberance 13 at inner housing 7 connect common effect as kayser.If on the contrary, shell body 8 is according in the position being illustrated at its second top in figure 10b, then making latch arm 10' be deflected into so that kayser nose 11' no longer stretches into and jointly acts in the hole 23 in shell body 8 and the most no longer with kayser protuberance 13.
At this, it is achieved in the deflection of latch arm 10', i.e. in the position on the second top of shell body 8, structure unblock protuberance 22 latch arm 10' at is no longer in the window portion 15' of shell body 8, but the wall below the lower limb 17 from window portion 15' or the window portion that the is arranged in 15' from shell body 8 is deflected outward by.This position is shown in the enlarged drawing according to Figure 11 b.If on the contrary, shell body 8 is positioned in the position of the first, bottom, then unlocks protuberance 22 and stretch in the window portion 15' in shell body 8 (Figure 11 a), so that latch arm 10' does not deflects.So, kayser nose 11' stretches in hole 23, and such as this can find out from Figure 10 a.
In addition can be seen that from the diagram according to Figure 10 a, kayser nose 10' has rake 18', and it rises on the direction of the base surface 21 of recess 4.Thus, rake 18' also simplify connector module 2 to the desired insertion in the recess 4 in base house 3.In addition, kayser nose 11' also has substantially relative with rake 18' card locking face 19', card locking face 19' stretches with an angle of the base surface 21 relative to recess 4 equally, and wherein, card locking face 19' tilts relative to base surface 21 from latch arm 10' to the free end of kayser nose 11'.Being therefore prevented from, connector module 2 can undesirably be forced out in the position of kayser from recess 4, because the inclination of card locking face 19' prevents kayser protuberance 13 to slip at kayser nose 11'.
As in particular can be from Fig. 1 a, 2a, 3, as finding out in 5 and 6, inner housing 7 has multiple kayser nose 24, in shell body 8, construct the corresponding kayser recess 25 of respective numbers relative to multiple kayser noses 24, each kayser nose 24 is joined in kayser recess 25.The kayser recess 25 in the hole being configured to window is used herein to, it is achieved that shell body 8 is relative to the desired limited mobility of inner housing 7.Here, can be seen that from the comparison of Fig. 1 and 2, in the position of the first bottom of shell body 8, kayser nose 24 abuts in the upper edge of kayser recess 25, and in the position on the second top of shell body 8, kayser nose 24 abuts in the lower edge of kayser recess 25.Jointly acted on kayser recess 25 by kayser nose 24, on the one hand, achieve the desired movement between shell body 8 and inner housing 7, on the other hand, it is therefore prevented that shell body 8 is taken off at inner housing 7 completely.If shell body 8 is lifted so far forth, make kayser nose 24 abut in the lower edge of kayser recess 25, then further lifting or pulling at shell body 8 causes connector module 2 entirety to be drawn out from the recess 4 the base house 3 of plant bottom case 1.
Here, thus simplify connector module 2 lifting or pulling out from plant bottom case 1 further for user, i.e. shell body 8 is respectively provided with grip surfaces 26 at the side 14 that it is relative.Not only to plug and in order to extract, user can catch connector module 2 simply by the two of a hands finger at relative grip surfaces 26, and or be inserted in recess 4 or first unclamp locking and afterwards by further pulling on connector module 2 pull-out from recess 4 completely by it by pulling at shell body 8.
Finally, overview Figure 4 and 5 are it is also seen that construct two guiding grooves 27 respectively and construct at two sides 14 of shell body 8 and guide flank 28 in two relative walls 16 of plant bottom case 1.Thus, not only in the case of extracting from plant bottom case 1, ensure that the guiding of connector module 2 being inserted on plant bottom case 1, and thus prevent bending.In a second embodiment, the arrangement exchange of guiding groove and guiding flank, say, that construct two guiding grooves 27 at two sides 14 of shell body 8 respectively and construct two corresponding guiding flanks 28 at two relative walls 16 of plant bottom case 1 respectively.
