Description

Technical area

[0001] The invention relates to a connector and a mounting method for a connector, for or on a cable, in particular a coaxial cable. State of the art

[0002] Housings, especially plastic housings, for coaxial connectors are designed to enclose the electrical (connector) contact(s) and ensure mechanical closure of the entire (connector) system. The basic structure of the entire (connector) system comprises a pin housing and a coupler housing. In each pin and coupler housing, a primary locking mechanism ensures that the contact(s) are and remain fixed in the respective housing. Optionally, each pin and coupler housing can also have secondary locking mechanisms to further ensure mechanical closure (of the primary locking mechanism). In addition, an additional optional security feature (so-called Connector Position Assurance - CPA) can prevent the connector connection from being accidentally released. The above-mentioned housing variants can alternatively be designed to be waterproof.

[0003] In the automotive sector, this primarily concerns all known FAKRA and mini-coax systems. Standards and specifications contain well-known requirements for primary and secondary locking, mating security, ease of assembly and disassembly, and the like.

[0004] In the current state of the art, lateral joining of the secondary locking mechanism is not possible in waterproof systems, as this would not create a closed (and thus leak-proof) housing. Furthermore, prior art (connector) systems usually feature a secondary locking mechanism that only locks the movable primary locking hook but does not provide any additional engagement. Such a design results in low mechanical stability. Furthermore, disassembly is often complicated or only possible through destruction.

[0005] Further disadvantages resulting from the current state of the art include a high degree of variance, or rather, the number of different geometries of the (connector) housings, for example, for a waterproof and a non-waterproof housing. This means that for these high variances, different equipment must be procured, which requires significant investments, and different processes, such as joining, mating, etc., must be performed. As a result, the effort and the production chain increase, ultimately making the product more expensive to manufacture. Description of the invention

[0006] It is therefore an object of the present invention to provide a connector and an assembly method which at least partially reduce the above-mentioned disadvantages.

[0007] The above-mentioned object is achieved by a connector according to claim 1 and an assembly method according to claim 9. Further advantageous embodiments of the invention can be found in the subclaims, the description, and the drawings.

[0008] In particular, the above-mentioned object is achieved by a connector for a cable, comprising: a housing, a through-opening formed in the housing along a first direction between a first side and a second side, a contact carrier which can be inserted into the through-opening for fastening the cable in the housing, wherein the contact carrier has first fastening means with which the contact carrier can be fastened to the cable, and the first fastening means are designed to be rigid or flexible, and the contact carrier has separate second fastening means with which the contact carrier can be fastened in the housing, and the second fastening means are designed to be flexible.

[0009] The present connector has a primary locking mechanism by means of the contact carrier, with locking taking place at two separate (i.e., spatially separated) points. A first latching or locking mechanism between the cable and the contact carrier at the first fastening means, and a spatially separated second latching mechanism between the contact carrier and the housing via the second fastening means. In particular, the first and second fastening means are arranged on opposite sides of the contact carrier. The first and second fastening means are designed to ensure reliable locking and mechanical stability. The first fastening means cannot (unintentionally) become loose.Due to their spatially separated arrangement, the second fastening means can be designed to be elastically deformable, whereby the contact carrier and the connector as a whole nevertheless offer reliable mechanical stability. In particular, the second fastening means are arranged on a first side or cable outlet side of the connector. The first side lies opposite a second side or plug-in side, onto which the connector can be plugged with a matching mating connector. The spatial separation of the functions, in particular the separation of the primary locking mechanism from the plug-in side of the connector, enables a connector with a small installation space, as well as high reliability and mechanical stability. In particular, the primary locking mechanism is spatially separated from a plug-in face of the connector. This means that the primary locking mechanism does not hinder an optional mating locking mechanism.A mating lock can be designed independently of the primary locking mechanism and in any desired configuration, allowing for a wide range of different mating patterns within the same housing. This keeps the number of components to a minimum.

[0010] Preferably, the connector further comprises at least one opening extending transversely to the first direction between the through-opening and an outer surface of the housing. The second fastening means engage in the at least one opening as an undercut upon complete insertion of the contact carrier into the housing. The undercut provides reliable mechanical stability and locking in a small space. Furthermore, the engagement in the undercut can be released from the outside through the opening, allowing for simple and non-destructive disassembly of the connector.

[0011] The contact carrier preferably has a gap along the first direction, wherein the gap is arranged in a first section. The gap makes it possible to attach the contact carrier to the cable laterally and / or by a tilting movement. This allows the contact carrier to be arranged at any position on the cable. The contact carrier can thus be inserted directly into a recess on the cable, at least in the first region. A first and / or second seal seals the interior of the housing against external environmental influences such as water or dirt when the contact carrier is inserted.

[0012] The through-opening preferably has a tunnel section whose inner diameter is selected such that, when the contact carrier is fully inserted into the housing, the cable is prevented from becoming detached from the contact carrier, and in particular from the first fastening means. When the contact carrier is inserted into the tunnel section, the rigid or flexible first fastening means on the contact carrier, together with the inner wall of the tunnel section, form an insurmountable barrier for the cable, so that the cable cannot become detached accidentally without the contact carrier being removed from the housing. This achieves a very high level of reliability of the primary locking mechanism on the connector.

[0013] The contact carrier is preferably constructed in one piece, with the contact carrier comprising at least a first and a second region, which are preferably formed together using a two-component injection molding process, with the first region having a rigid or flexible shape and the second region having a flexible shape. The one-piece construction of the contact carrier enables simple assembly. The possibly different flexibilities of the material in different regions of the contact carrier enable optimal adaptation of the fastening or locking means to the spatial conditions on the housing, thus achieving good mechanical stability with optimal space utilization (in a small space).

[0014] The second region preferably has a larger diameter than the first region. The larger diameter, in particular a larger inner diameter, in the second region, firstly facilitates the insertion of the cable into the contact carrier. Secondly, tilting of the cable in this region is enabled, so that, for example, first fastening means (tilted out) can be guided (at least partially) past a contact region of the cable and then arranged again (tilted in) on the cable. Finally, the larger diameter enables a gap between the cable and the second fastening means, so that the second fastening means can be moved flexibly in order to engage or disengage the locking mechanism.

[0015] The connector preferably further comprises a cap which can be locked to the housing and closes off the housing on the first side and the at least one opening. The cap allows a connector to be protected very easily. No changes to the housing are necessary, which for example keeps the number of different housing components and process steps to a minimum. The cap protects the connector on at least two different sides, e.g. on the cable outlet side and to the side thereof. Locking the cap to the housing offers additional retention, which increases the reliability of the connector, in contrast to simply placing it on or plugging it onto / into the housing as in the prior art. Finally, by covering the at least one opening, the cap protects against accidental release of the second fastening means from the outside.

[0016] The cap preferably has a projection, which, when the cap is locked to the housing, exerts a preload on the contact carrier. Due to the projection, the cap exerts a preload on the contact carrier and thus holds the contact carrier in position. In particular, (material) fatigue phenomena, which can lead to unwanted play of the contact carrier in the housing, are compensated for by the preload. Due to the projection, the cap fulfills not only its protective function but also the function of a secondary locking mechanism. The secondary locking mechanism offers protection against accidental release of the contact carrier's locking mechanism in the housing and increases the reliability of the connector.Furthermore, the volume of the projection is preferably formed such that, if the contact carrier is not fully inserted into the housing, the cap either cannot be fully locked onto the housing and thus serves as an indicator of an incorrectly mounted connector, or the cap pushes the contact carrier into the fully inserted position when locked onto the housing, whereby both options also increase the reliability of the connector.

[0017] The above-mentioned problems are further solved in particular by an assembly method for a plug connector to a cable, in which the plug connector comprises at least one housing and a contact carrier which can be arranged in the housing, and the assembly method has the following steps: providing the cable along a first direction, arranging the contact carrier on the cable, by plugging it on or a tilting movement, from a direction transverse to the first direction, and inserting the contact carrier with the cable into the housing along the first direction until the contact carrier locks into the housing.

[0018] The step of arranging the contact carrier on the cable by lateral insertion and / or a tilting movement transverse to the first direction enables the rigid or flexible first fastening means to be arranged in a recess on the cable without the first fastening means having to be displaced on the cable. Displacing the first fastening means on the cable can lead to damage to the cable and / or the fastening means. The material thickness and / or shape of the first fastening means achieves a high level of fastening reliability when the contact carrier is subsequently fully inserted into the housing. Inserting the contact carrier along the first direction into the housing, in turn, enables the formation of a waterproof connector and keeps the assembly of the connector simple.

[0019] Preferably, the step of arranging the contact carrier on the line comprises laterally attaching it transversely, in particular perpendicularly, to the first direction, or guiding it along the first direction, wherein the second central axis of the contact carrier is aligned transversely to the first direction, and then tilting it so that the second central axis is aligned on the line along the first direction. Guiding it along the first direction, wherein the second central axis is aligned transversely to the first direction, serves to move the rigid or flexible first fastening means next to the line until the first fastening means can be arranged at a suitable location on the line, namely a recess. Tilting it onto the line takes place at this suitable location.

In this figure: Fig. 1 is a perspective view of an embodiment of a connector; Fig. 2 is a cross-sectional view of the embodiment of the connector from Fig. 1 along the first direction; Fig. 3 shows a perspective view of an embodiment of a housing; Fig. 4 shows a perspective view of an embodiment of a contact carrier; Fig. 5 shows a further perspective view of the embodiment of the contact carrier from Fig. 4 ; Fig. 6 a cross-sectional view of the embodiment of the contact carrier from Fig. 4 along the first direction; Fig. 7 is a perspective view of an embodiment of a line provided with a contact area; Fig. 8 is a perspective view of an embodiment of the line from Fig. 7 , on which a contact carrier is arranged; Fig. 9 a perspective view of an embodiment of the line from Fig. 7, on which a cap is arranged; and Fig. 10 a perspective view of an embodiment of the line from Fig. 7 , on which a cap and a contact carrier are arranged.

[0021] In the following, preferred embodiments are described in detail with reference to the accompanying figures.

[0022] Fig. 1 shows an embodiment of a connector 1 for a cable 2. The connector 1 makes it possible to connect the cable 2 to a matching mating connector, which can be attached to another cable or an end user.

[0023] The connector 1 has at least one housing 10. The housing 10 is preferably made of plastic and has dimensions in the range of a few millimeters to a few centimeters. In the assembled state, the housing 10 extends on a cable 2 from a first side S1, the so-called cable outlet side, to an opposite second side S2, the so-called plug-in side, to which the connector 1 can be plugged with a matching mating connector. Plugging occurs by inserting the mating connector into the receptacle 13 on the plug-in face of the connector 1, wherein a mating lock can optionally be used to ensure that only a matching mating connector can be successfully plugged into the connector 1.

[0024] A through-opening 12 is formed in the housing 10 (see Fig. 2 and 3). The through-opening 12 runs in the housing 10 along a first direction X, which also forms the plug-in direction of the plug connector 1 with a mating plug connector. The through-opening 12 runs between the first side S1 and the second side S2. The through-opening 12 has at least one tunnel section T, the inner diameter of which is selected such that, when the contact carrier 20 is fully inserted into the housing 10, detachment of the line 2 from the contact carrier 20, and in particular from the first fastening means 21, is prevented or blocked. At the end of the tunnel section T on the second side S2, at least one stop 15 is arranged or formed, which signals maximum insertion of the contact carrier 20 when brought into stop.

[0025] The illustrated connector 1 further comprises a contact carrier 20 which can be inserted into the through-opening 12. A preferred embodiment of the contact carrier 20 is shown in Fig. 4 shown. The contact carrier 20 is fastened to the cable 2 before being inserted into the housing 10 or the through-opening 12. The contact carrier 20 serves to fasten the cable 2 in the housing 10. The contact carrier 20 is a hollow body whose second central axis M2 is arranged along the first central axis M1 of the housing 10 when the contact carrier 20 is in the fully inserted state in the housing 10. In the fully inserted or mounted state, the cable 2 is aligned in the region of the connector 1 along the first direction X and the first central axis M1.

[0026] The contact carrier 20 shown has at least first fastening means 21, with which the contact carrier 20 can be fastened to the line 2. The first fastening means 21 shown are rigid or stiff or dimensionally stable. In an alternative embodiment, the first fastening means 21 can be flexible. An example of a flexible first fastening means 21 is a latching hook. The first fastening means 21 are preferably formed as projections which are formed integrally with the contact carrier 20. The first fastening means 21 can be elastically deformable or non-elastically deformable. The first fastening means 21 are arranged at a corresponding point on the line 2 and form a type of pre-fixing of the contact carrier 20 to the line 2. In interaction with the housing 10 orIn the tunnel section T of the through-opening 12, the first fastening means 21 form a (final) fixation of the line 2 in the housing 10 when the contact carrier 20 is fully inserted into the housing 10, since the line 2 cannot be removed from the fastening without the contact carrier 20 being removed from the housing 10.

[0027] The illustrated contact carrier further comprises at least second fastening means 22, with which the contact carrier 20 can be secured in the housing 10. The second fastening means 22 are flexible, i.e., elastically deformable. This flexibility is achieved by the selection of the elastically deformable plastic material. The second fastening means 22 are designed, in particular, as an at least partially circumferential projection with respect to the contact carrier 20. The second fastening means 22 can be compressed radially and expand radially outward again when the compression force is removed.

[0028] The Fig. 3The illustrated housing 10 of the plug connector 1 further comprises at least one opening 14 which extends transversely to the first direction X between the through-opening 12 and an outer surface of the housing 10. The at least one opening 14 is preferably formed during the formation of the housing 10, but it can also be introduced into the housing 10 subsequently. The at least one opening 14 preferably has the shape of a slot. The second fastening means 22 can engage in the at least one opening 14 as an undercut when the contact carrier 20 is fully inserted into the housing 10 and thereby fasten the contact carrier 20 to or in the housing 10.

[0029] The contact carrier 20 shown can be divided into a first section A1 and a second section A2 (see Fig. 6). The first section A1 can be rigid or flexible and comprises the first fastening means 21. The second section A2 is flexible, at least in the region of the second fastening means 22. The contact carrier 20 shown is of one-piece construction. The contact carrier 20 shown can be further subdivided. When subdivided, the contact carrier 20 comprises at least a first and a second region B1, B2, which are connected to one another via a base 23. The first and second regions B1, B2 were preferably formed together in a 2K injection molding process. The first region B1 lies in the first section A1, has a rigid or flexible shape, and forms the region of the first fastening means 21 along the first direction X. The second region B2 lies in the second section A2, at the opposite end of the contact carrier 20 along the first direction X with respect to the first region B1.The second region B2 has a flexible shape and forms the region of the second fastening means 22 along the first direction X. The second region B2 further has a larger second (inner) diameter D2 than the first region B1 with a first (inner) diameter D1. The larger second diameter D2 in the second region B2 allows play or tilting of the line 2 in the second region B2. The first diameter D1 in the first region B1 lies closely against the line 2 or is even slightly smaller than the outer diameter of the line 2 in large parts, so that the first region B1 can only be arranged in a section of the line 2 provided for this purpose, the recess 8, which has a smaller outer diameter.

[0030] Fig. 7shows a preferred embodiment of a line 2. The line 2 shown comprises a coaxial line or a coaxial cable, with a contact area 3. The contact area 3 has at least one crimp sleeve 4, an inner conductor contact 5 (see Fig. 2 ), an outer conductor contact 6, and a recess 8. The illustrated recess 8 is formed between the outer conductor contact 6 and the crimp sleeve 4. In alternative embodiments, the recess 8 can also be formed on the cable 2 at a different position or by other components, or sections with partially removed layers of the cable 2. The recess 8 is preferably formed circumferentially, so that the cable 2 can be arranged in the first fastening means 21 at any circumferential section.

[0031] The illustrated contact carrier 20 further has a gap 24 across the first section A1 along the first direction X. A first and second seal 25, 26 are arranged at least partially circumferentially in the circumferential direction and, when fully inserted, seal the through-opening 12 toward the first side S1. The first and second seals 25, 26 are flexible, i.e., elastically deformable.

[0032] For a protected connector 1, the connector 1 further comprises a cap 30 (see Fig. 1 , 9 and 10). The cap 30 can be locked to the housing 10 and protects the housing 10 on the first side S1 and the at least one opening 14. The illustrated cap 30 further comprises a projection 34. The illustrated projection 34 is formed integrally with the cap 30 from plastic and is designed to extend circumferentially. When the cap 30 is locked to the housing 10, the illustrated projection 34 exerts a preload on the contact carrier 20 and thereby prevents the second fastening means 22 from disengaging from the undercut of the at least one opening 14.

[0033] In the following, with reference to the Figs. 7 - 10 , a mounting method for a connector 1 shown to a cable 2 is described. The mounting method comprises at least the following steps: First, a cable 2 is provided along a first direction X, as shown in Fig. 7shown. If a protected connector 1 is mounted, the cap 30 is first pushed along the first direction X from the second side S2 towards the first side S1 or from the outer conductor contact 6 towards the cable outlet onto the cable 2 (see Fig. 9 ). Sliding on the cap 30, as well as all assembly steps, can be done manually, but is preferably automated.

[0034] The contact carrier 20 is then arranged on the line 2. In one embodiment, the contact carrier 20 shown is first pushed onto the line 2, wherein the contact carrier 20 is aligned transversely to the first direction X, i.e. at least partially along a second or third direction Y, Z, so that the first fastening means 21 run next to the line 2. Only when the first region B1 is located along the first direction X at the level of the recess 8 does a tilting movement of the contact carrier 20 onto the line 2 take place, so that the contact carrier 20 is aligned along the first direction X (see Fig. 8 and 10 ). In this orientation, the first fastening means 21 and the cable 2 are in the previously mentioned pre-fixation.

[0035] Subsequently, the contact carrier 20 with the cable 2 is inserted into the housing 10 along the first direction X until the contact carrier 20 locks into the housing 10. Locking means, on the one hand, that the insertion is continued until the first area B1 of the contact carrier 20 comes into contact with the stop 15 in the through-opening 12. And, on the other hand, that during insertion, the second fastening means 22 are automatically compressed upon entry into the housing 10. Only when the second fastening means 22 reach the at least one opening 14 when the contact carrier 20 is fully inserted into the housing 10 do they expand again and form an engagement with the housing 10. This engagement secures the contact carrier 20 to the housing 10.The engagement can be released if the second fastening means 22 are pressed together radially inwards from the outside, preferably with aids, and the contact carrier 20 is simultaneously moved out of the housing 10.

[0036] Particularly in the case of a protected connector 1, the cap 30 is finally moved along the cable 2 in the direction of the housing 10 until fastening means 32 on the cap 30 engage or lock with locking means 19 on the housing 10 (see Fig. 1). The locking secures the cap 30 to the housing 10 and also prevents unintentional removal of the contact carrier 20 from the housing 10. In order for the illustrated cap 30 to lock with the projection 34 on the housing 10, the contact carrier 20 must be in the fully inserted position or the fully assembled state. If the contact carrier 20 is not in the fully inserted position, the contact carrier 20 can be moved into the fully inserted position either by exerting increased pressure on the cap 30 in the direction of the housing 10 until the cap 30 locks onto the housing 10. Or the non-locking of the cap 30 serves as an indicator that the connector 1 has not been properly assembled. The locking or non-locking is easily visible from the outside and could be detected in particular by automated testing processes.

[0037] The locked cap 30 can be removed from the housing 10 without causing any damage, preferably with the aid of tools. During complete disassembly of the connector 1, the second fastening means 22 are subsequently released from the housing 10 or from the at least one opening 14, preferably with the aid of tools. At the same time, the contact carrier 20 is removed from the housing 10, or the housing 10 is pulled off the contact carrier 20 via the outer conductor contact 6. Finally, the contact carrier 20 and the cable 2 are separated from one another by tilting the first fastening means 21 out of the recess 8 on the cable 2 and / or removing them laterally.

[0038] The described preferred embodiments have the following functions in summary with regard to a primary and secondary locking mechanism. The contact carrier 20 and the housing 10 are two separate components which, when assembled, fulfill the function of a primary locking mechanism (for the cable 2 in the connector 1). With this primary locking mechanism, the functions of 'fixing the cable 2 in the contact carrier 20' and fixing the contact carrier 20 in the housing 10' are implemented at two different locations. The cable 2 is fixed in the contact carrier 20 via the first fastening means 21 in the first region B1. The contact carrier 20 is fixed in the housing 10 via the separate second fastening means 22, which are spatially separated along the contact carrier 20, in the second region B2. By spatially separating the two functions, the structure of the connector 1 can be kept very small yet mechanically stable.A secondary locking mechanism can be optionally added. The secondary locking mechanism is formed by the projection 34 of the cap 30 exerting a preload on the contact carrier 20. The present secondary locking mechanism thus does not act as a barrier against the release of the primary locking mechanism from the cable, as in the prior art, but rather as a barrier against the release of the contact carrier 20 from the housing 10, indirectly also preventing (accidental) release of the cable 2 from the contact carrier 20. Due to the operating principle of the present secondary locking mechanism, the connector can be constructed very effectively and, for example, advantageously combine the function of the secondary locking mechanism with the function of (additional) protection. Additional safeguards such as a CPA can be arranged on the primary and secondary locking mechanisms on the housing 10 without any disadvantages. LIST OF REFERENCE SYMBOLS
