Definitions
- the invention is based on a contact carrier according to the preamble of independent claim 1.
- the invention is also based on a method for assembling a plug contact in a contact carrier according to one of claims 7 to 9.
- Contact carriers of this type are required to hold at least one plug contact inserted therein and to absorb the plug forces acting thereon during the plugging process.
- the plug contact can
- a cable connection area namely one
- Crimp connection and a plug area on the plug side, e.g. one
- the plug-in area and the cable connection area can have a middle collar.
- the plug contact can have a connection-side collar at its connection-side end.
- the middle collar of the plug contact has one in this design
- connection-side i.e. in the direction of the cable connection, bevel to remove the plug contact from it
- the middle collar has the function, together with the connection-side collar, of guiding the plug contact within the contact carrier and centering its plug region in a hollow cylindrical through opening of the contact carrier. Furthermore, the middle collar also has a holding surface on the plug side, that is to say in the direction of the plug region.
- Holding surface can interact with the contact carrier in order to prevent the plug contact from being immersed too deeply in the direction of the plug side of the contact carrier.
- the corresponding contact carrier can be used
- the crimp connection of the plug contact is basically elongated. This elongation varies depending on the type of crimping process, e.g. depending on the type of crimping tool, the crimping machine or others
- Crimping tools The change in length of the crimp connection is therefore not yet exactly quantifiable when the plug contact and / or the contact carrier is in the free position.
- an additional locking means for example a locking cone, secures the contact element in a one-piece contact carrier and absorbs the plug-in forces between the cable connection area and the plug-in area.
- a disadvantage of this design is that at least one additional locking means is required to fix the electrical contacts, for example in the form of a snap ring, one
- Locking clips the locking cone or a locking hook.
- DE 196 31 467 A1 has a multi-pole plug connection with a plurality of plug contacts, each of which is received in a through opening of a multi-part contact carrier.
- a locking projection projecting from one side of the through opening engages in a holding recess in the central section of the plug contact and supports the plug contact against axial loading.
- One of the The spring tongue on the opposite side holds the plug contact in its assembled position.
- the object of the invention is to provide a contact carrier, which is possibly also able to insert one inserted therein
- a contact carrier has a plug-in side and a connection side opposite and serves to receive and attach one
- Plug contact which has a crimp connection and a middle collar with a bevel on the connection side.
- Contact carrier has an insulating body and a mounting plate that can be attached to it on the connection side. Furthermore, the contact carrier has at least one latching element which, in the unmounted state, can assume both a position which latches the plug contact and a position which unlatches the plug contact.
- the latching element is part of the insulating body according to the invention.
- the holding plate also has at least one locking element which, in the assembled state, fixes the at least one locking element in its position locking the plug contact and thus prevents its transition from the locking position to the unlocking position.
- connection side includes and below
- Cable connection side and / or at least inclined or aligned in the direction of the respective cable connection side.
- Connection side basically stands for cable connection side.
- the latching element can preferably be a latching arm.
- the invention is of particular advantage because the plug contact may be locked in this way on the insulating body instead of on the holding plate.
- the mounted holding plate in turn, merely ensures that the at least one latching element of the insulating body is fixed in its position in which the plug contact is locked by the locking element.
- the holding plate itself does not absorb any insertion forces.
- the contact carrier can absorb the forces occurring in the plugging process particularly effectively, because the holding plate is naturally in the direction of the Connection side - and thus in their dismantling direction - acting plug forces relieved.
- the contact pin it is thus possible for the contact pin to be particularly stable and reliable in its central collar
- the at least one latching element is fixed in its latching position by the locking element and, in the fixed state, cannot be moved into its latching position in spite of the beveling of the middle collar on the connection side, even under particularly strong insertion forces.
- those contact pins can thus also be fixed centrally in the contact carrier, which would otherwise not be able to be locked in the contact carrier with sufficient holding force due to the beveling of their central collar on the connection side.
- Such a central fixation that is to say a locking on the central collar to prevent unlatching, is furthermore particularly advantageous for the following reasons:
- Contact carrier can impact.
- the contact carrier according to the invention By means of the contact carrier according to the invention, it is also possible to use the plug contacts, the middle collar of which has a bevel on the connection side, that is to say, for example, the contacts from the HARTING company of the Han C type.
- the plug contacts can be manufactured inexpensively in this form using existing manufacturing processes and equipment.
- they have already proven themselves in the present form in relation to many other quality criteria.
- the contact carrier according to the invention thus makes a contribution to the compatibility of existing plug contacts for different latching methods and is all the more cost-effective to produce in large series.
- this type of plug contact can be used universally.
- Plug contacts do not have to be held on their connection-side collar in conventional contact carriers, but can
- the insulating body can be a
- the at least one latching element can each be a latching arm which is integrally formed on the through opening and projects into the through opening for latching the plug contact, in particular with a latching lug integrally formed thereon.
- the insulating body preferably has at least two such latching arms. At least are particularly preferred three, in particular at least four locking arms inside the
- the insulating body thus has at least two, in particular at least three, preferably at least four, for example two, three, four, five, ..., n latching arms for latching the inserted plug contact on its central collar and thus for preventing movement of the plug contact in the direction the connection side of the contact carrier.
- the contact carrier can have at least two, in particular at least three, preferably at least four, that is to say for example two, three, four, five,..., N holding elements which on the inside of the
- Insulating bodies are molded on and prevent the plug contact from being moved deeper into the plug side of the contact carrier.
- One of the said ones can advantageously always be used
- Holding elements can be arranged between two of said locking arms.
- the latching arms and the holding elements can be integrally formed on an encircling inner collar formed in the through opening, as a result of which they have particularly great stability and can absorb particularly large insertion forces.
- the holding plate can have a square or at least rectangular base plate with a preferably circular insertion opening.
- the locking element can be a locking sleeve molded onto the base plate, through which said insertion opening runs.
- the locking sleeve has a hollow cylindrical basic shape. Then the outer radius of the locking sleeve can be smaller than the inner radius of the
- the locking sleeve can in particular be non-positively arranged between the at least one latching element, in particular the at least one latching arm, and an inside of the through opening of the insulating body.
- the locking sleeve prevents the at least one latching element from moving outwards, that is to say towards the inside of the through opening, and thus prevents the transition of the latching element from the position that locks the plug contact into the position that unlocks it.
- the holding plate itself can be locked in two different positions on the insulating body, namely in an assembly position and a locking position.
- the locking position corresponds to the assembled state in which the plug contact is finally held stable in the contact carrier.
- the contact carrier can thus absorb particularly high insertion forces.
- the holding plate can have two fastening plates for this purpose, which are arranged on two opposite sides of the base plate at right angles to the latter.
- two latching windows namely a first latching window and a second latching window, can be arranged on each fastening plate.
- the insulating body can have, on two opposite outer sides, a recess which adjoins the connection side and runs in the direction of the plug-in side and is open to the outside and is delimited by two outer webs.
- One of the mounting plates is then each in the respective recess for mounting the contact carrier
- Retaining plate in particular, can be inserted precisely between the webs.
- In the area of the depression are on the respective outside of the Insulating body each arranged with the locking windows of the mounting plates corresponding to each other in the insertion direction offset locking projections, namely a first and a second
- the mounting of the contact carrier with the plug contact can take place as follows:
- Depressions of the insulating body initially latch the respective first snap-on molding of the insulating body in the second snap-in window of the respective mounting plate. The is in this state
- the plug contact which is, for example, a pin or socket contact, can be crimped on the connection side with an electrical stranded conductor of an electrical cable. Then the plug contact, with its plug area ahead, through the
- Insulating body inserted and locked in its final assembly position. A deeper insertion of the plug contact is prevented by the striking of its middle collar on the at least one further internal projection. For locking, the locking arms of the insulating body engage behind the bevelled middle collar. In this state, the plug contact is still in the cable connection direction under the influence of a sufficiently high plug-in force from the plug-side direction (or pulling force from the connection-side direction)
- the holding plate is moved from its loading position into its final locking position.
- the contact carrier is finally assembled and the plug contact is in its final assembly position fixed with the desired high holding force in the contact carrier.
- the locking sleeve is arranged between the locking arms and the inside of the through opening.
- the locking sleeve prevents an outward movement of the latching arms, ie movement toward the inside of the through opening.
- the locking arms are therefore locked against a transition to their unlocking position.
- the plug contact cannot push the latch arms apart even under the influence of high plug-in forces, despite the bevelled side of its central collar. It is therefore held in a particularly stable manner in the contact carrier.
- the high insertion forces are possibly absorbed by the insulating body on which the locking arms are finally arranged.
- the holding plate does not experience any unlocking / disassembling forces.
- FIG. 3 shows a contact carrier, comprising the insulating body and the holding plate locked thereon in an assembly position together with the plug contact to be inserted therein;
- Plug contact 1 In the present example, it is designed as a pin contact, since its plug area is formed by a contact pin 11. In a further embodiment, a socket contact can be made in the same way
- the plug contact 1 has a cable connection area, which as
- Crimp connection 12 is executed.
- the plug contact 1 is therefore also referred to in technical jargon as a “crimp contact”.
- the crimp connection 12 is sleeve-shaped, namely hollow-cylindrical, and therefore has a cylindrical crimp opening 120, and has a collar 14 on the connection side at its free end.
- this plug contact 1 could be held on its connection-side collar 14 for receiving plug-in forces acting in the connection direction. Then, however, the lengthening of its crimp connection 12, which varies depending on the crimping method, results in structural disadvantages, which are explained in more detail below.
- a middle collar 13 is arranged between the plug-in area 11 and the crimp connection 12.
- the middle collar 13 has on the one hand the function, together with the collar 14 on the connection side, for guiding the plug contact 1 within the respective contact carrier and centering the contact pin 11, for example in a hollow cylindrical through-opening of the contact carrier.
- the middle collar 13 has a holding surface 131 on the plug side. This can prevent the plug contact 1 from being too deep when it is inserted
- the plug contact 1 in the conventional contact carrier has a correspondingly large amount of play in the plug direction. If the elongation is greater than expected, it can cause difficulties with the
- the middle collar 13 also has a bevel 132 on the connection side.
- the plug-side holding surface 131 is also beveled in the present embodiment, but this does not play a significant role for the following considerations .
- the connection-side collar 14, on the other hand, does not require a bevel on the connection side, since it is arranged anyway on a connection side of the conventional contact carrier and therefore does not cause any appreciable resistance when it is removed
- an arrangement which comprises an insulating body 2 shown in FIG. 2a and a holding plate 3 shown in FIG. 2b.
- the insulating body shown in FIG. 2a is essentially cuboid. It has a central cylindrical one
- Insulating body 2 are executed.
- Each of the two depressions 28 is delimited by two lateral webs, which are also not provided with reference numerals for reasons of clarity.
- two locking projections 284, 284 ' are offset from one another in the plugging direction, namely a first locking projection 284 and a second
- Rastanformung 284 ' arranged. These each have a sliding slope and a locking arm, which are not provided with a reference symbol for reasons of clarity.
- each folding element 231 and four latching elements 232 are formed in alternating order on a circumferential inner collar 23.
- the latching elements are latching arms 232 which are used to latch the central collar 13 of the
- the pleat elements 231 each have a pleat section 2311 in order to hold the plug contact 1 on its plug-side holding surface 131 of its central collar 13 and thus to move the flin deeper Prevent plug contact 1 in the direction of a plug side S of the contact carrier K.
- Base plate 32 with an insertion opening 330, which is through a
- a mounting plate 38 is formed at right angles thereto.
- two locking windows 384 namely a first locking window 384 and a second locking window 384 ' , are arranged on each fastening plate 38.
- FIG. 3 shows the contact carrier K, which has the insulating body 2 and the holding plate 3 locked thereon in a fitting position, as a result of which the contact carrier is in a fitting state.
- the plug contact 1 can be inserted into the contact carrier K from the connection side A.
- the pin contact 1 is crimped beforehand at its crimp connection 12 with an electrical stranded conductor, not shown in the drawing.
- the first latching windows 384 latch
- connection side A and the plug side S lie opposite each other.
- the contact carrier K has a plug-in side S.
- the first latching window 384 latches on the first latching projection 284 and the second latching window 384 ' on the second latching projection 284 ' , as it is shown in Fig. 4a.
- the holding plate 3 is thus in its locking position.
- the contact carrier K is then together with the inserted plug contact 1 in its assembled state, in which illustration from
- FIG. 4b shows the mounted contact carrier K with a view of the
- 5a and 5b show the assembled contact carrier K in cross section through the holding elements 231 and through the latching arms 232.
- Holding surface 131 of its central collar 13 on the holding section 2311 of the holding elements 231 is secured against its deeper insertion in the direction of the plug side S. It is also easy to see that the Holding elements on the circumferential inner collar 23 of the
- Insulating body 2 are molded.
- latches 2322 fasten the plug contact 1 to the bevel 132 on the connection side of its central collar 13 against movement in the direction of the connection side A.
- the locking sleeve 33 is non-positively arranged between the locking arm 232 and an inside of the through opening 20 of the insulating body 2. As a result, the locking sleeve 33 prevents the latch arms 232 from moving outwards, i.e. towards said inside of the through opening 20, and thus prevents the transition of the
- the plug contact 1 could, under the action of plug-in forces which press it in the direction of the connection side A, with its bevel 132 on the connection side, the latching arms 232 without
- the plug contact 1 Due to the fully inserted into the insulating body 2 locking sleeve 33, the plug contact 1 is fixed in its final assembly position with the desired high holding force in the contact carrier 2.
- the locking sleeve 33 prevents an outward movement of the locking arms 323, that is to say toward the inside of the insulating body 2.
- the locking arms 323 are thus locked against a transition into their unlocking position.
- the plug contact cannot push apart the latching arms 232 even under the action of high plug-in forces. So he is kept particularly stable in the contact carrier K.
- the high insertion forces are possibly absorbed by the insulating body 2, on which the locking arms 232 are finally formed on the inside.
- the holding plate 3 does not experience any unlocking / disassembling forces.
