This application claims the benefit of the filing date under 35 U.S.C. § 119(a)-(d) of European Patent Application No. 20194283, filed on Sep. 3, 2020.
The present invention relates to a connector and, more particularly, to an angled connector.
Angled connectors are commonly used for detachable connections of electrical components for allowing, in the coupled state, the transmission of current and/or electrical signals. Since angled connectors allow a change of the plugging direction, they are particularly preferred in applications with tight space constraints.
However, the installation of the angled connectors has proven to be cumbersome. For example, the angled connector may comprise two housing shells, each carrying a respective terminal, wherein the two housing shells may be mounted to one another. The connection of the two housing shells needs to be sealed with a watertight sealing, which is complicated and prone to errors. Moreover, additional costs are incurred for the manufacture, transport and assembly of a multipart housing. Furthermore, a customer or operator is usually required to install the second terminal, for example a cable end terminal, on site. The first terminal, however, may be different to the second terminal; it may be an interface terminal. The customer or operator usually does not possess the necessary equipment for processing and installing the interface terminal, such as stamping equipment.
An angled connector includes a connector housing, a terminal support held by the connector housing, and a first terminal held in the terminal support. The connector housing has a first terminal passage and a second terminal passage extending at an angle to the first terminal passage. The first terminal passage and the second terminal passage intersect one another in an intersection region. The terminal support is slidable relative to the connector housing along the first terminal passage from a first position to a second position. The first terminal at least partially extends into the first terminal passage. The first terminal is closer to the second terminal passage in the second position than in the first position, and the first terminal is at least partially arranged in the intersection region in the second position.
The invention will now be described by way of example with reference to the accompanying Figures, of which:
In the following, the exemplary embodiments of the angled connector, according to the invention, are explained in greater detail with reference to the accompanying drawings.
In the figures, the same reference numerals are used for elements which correspond to one another in terms of their function and/or structure.
According to the description of the various aspects and embodiments, elements shown in the drawings can be omitted if the technical effects of these elements are not required for a particular application, and vice versa: i.e. elements that are not shown in the figures but are described herein can be added if the technical effect of those particular elements is advantageous in a specific application.
An angled connector 1 according to an embodiment is shown in
The first terminal passage 4 may extend along a longitudinal axis L being arranged at an angle, particularly essentially perpendicular, to the longitudinal axis L of the second terminal passage 6, whereby the longitudinal axes L of the respective passages may intersect one another in the intersection region 8. In an embodiment, the angled connector 1 may be an elbow connector, such as a 90° angled connector, wherein a longitudinal axis L of the first terminal passage 4 may be arranged at about 90° angle to the longitudinal axis L of the second terminal passage 6. However, other embodiments, such as 30° or 45° angled connectors, may also be provided.
The angled connector 1 further comprises a first terminal 10, the first terminal 10 being held in a terminal support 12 and at least partially extending into the first terminal passage 4, as shown in
In an embodiment, the connector housing 2, particularly the parts comprising the respective sections, may be formed as a monolithic component 14 or a unitary housing. Therefore, the passages 4, 6 may form a continuous through channel of the housing 2 and no cumbersome sealing of two composite housing parts, each forming a part of a passage, is necessary.
The connector housing 2, as shown in
As shown in
The first terminal 10 may particularly be an interface terminal 28, as shown in
In an embodiment, the interface end 30 of the first terminal 10 may be held by the terminal support 12. The terminal support 12 may particularly extend over less than half of the first terminal 10, the half being opposite the second terminal passage 6, in order to keep a weight of the angled connector 1 to a minimum and safe material costs. In other words, the terminal support 12 may extend over less than half of the first terminal 10 starting from the interface end 30.
The terminal support 12 may be adapted to hold only a tip of the first terminal 10, e.g. the interface end 30 of the first terminal 10, and at least partly be arranged outside of the first terminal passage 4 at least in one of the first and second position P, C, particularly in both positions. Thus, the terminal support 12 may be easily accessed, allowing a convenient actuation of the terminal support 12 for inducing movement between the first and second position.
The terminal support 12 of the first embodiment is further explained in detail with reference to
The interface end 30 of the first terminal 10 may be at least partially supported by a support collar 40, shown in
The columns 42 may be spaced apart from one another in a circumferential direction, as shown in
The securing latch 46 may be elastically deflectable and may, in an embodiment, be more flexible than the remainder of the support collar 40. For this, the length of the securing latch 46 in a direction essentially parallel to the longitudinal axis L of the first terminal passage 4 may be larger than the remainder of the support collar 40. Particularly, the free end comprising of or consisting of the radially inward protruding shoulder 48 may extend beyond the remainder of the support collar 40 towards the second terminal passage 6. This may lead to an extension of the lever arm of the securing latch 46, increasing the flexibility of the securing latch 46. To further increase the flexibility of the securing latch 46, the securing latch 46 may extend in the circumferential direction along less than a 40° arc, and in an embodiment less than a 30° arc. Hence, the first terminal 10 may be easily mounted to the support collar 40 by deflecting the securing latch 46 radially outwardly. The remainder of the support collar 40 may be rather rigid compared to the at least one securing latch 46.
When the terminal support 12 is mounted to the connector housing 2, the securing latch 46 may advantageously be supported by an inner surface 56 of the first terminal passage's 4 wall 22. Therefore, a deflection of the securing latch 46 radially outwards for disengaging the first terminal 10 may be prevented, further securing the first terminal 10 within the terminal support 12.
In order to secure the relative rotational position of the first terminal 10 and the terminal support 12 and/or ensure coupling of the first terminal 10 in a predetermined relative rotational position, the first terminal 10 and the terminal support 12 may comprise complementary formed keying features 58, of which only the keying feature 58 of the terminal support 12 is shown in
The slot 60 may be arranged opposite the at least one securing latch 46 separating two parts from the remainder of the support collar 40 in the circumferential direction. Therefore, the two parts of the support collar 40 being arranged adjoining to the slot 60, or at least one of the two, may be formed rather rigidly, for example by extending over a larger arc in the circumferential direction and/or a lower length essentially parallel to the longitudinal axis L of the first terminal 10. The rigidity of the support collar 40 adjoining the slot 60 may further secure the rotational lock provided by the complementary formed keying feature 58.
A rail may be provided as the complementary keying feature 58 formed on the first terminal 10. The rail may protrude radially outwards from the first terminal 10, particularly the interface end 30 of the first terminal 10 shown in
To ensure that the first terminal 10, particularly the connection end 38, does not interfere with the second terminal when the terminal support 12 is secured in the first position P shown in
A mode of securing the terminal support 12 in at least one of the first position P and the second position C is to secure the terminal support 12 against movement in at least one direction essentially parallel to the longitudinal axis L of the first terminal passage 4 by a form lock. In this case, the terminal support 12 may be a terminal position assurance 61. For this, the terminal support 12 may comprise a locking latch 62, which can be seen in
The locking latch 62 may be adapted to lock the terminal support 12, at least in the first position P, and in an embodiment in both positions P, C. Therefore, the operator does not have to worry about accidental movement of the terminal support 12 during insertion of the second terminal 80 into the second terminal passage 6. The operator does not have to hold the terminal support 12 or the first terminal 10 and thus has both hands to his/her disposal for the insertion of the second terminal 80.
In an embodiment, the at least one locking latch 62 and the connector housing 2 may form a form lock in at least one of the first and second position P, C. With the form lock, wear on the connector housing 2 as well as the terminal support 12 may be reduced and lower forces may be necessary to push the terminal support 12 from the first position P to the second position C or vice versa. Only an initial force for deflecting the at least one locking latch 62 out of engagement of the form lock is necessary for inducing a relative movement of the terminal support 12 essentially parallel to the longitudinal axis L relative to the first terminal passage 4.
A snap nose 64 may be formed on a free end of the locking latch 62, protruding radially inwards and being adapted to engage a notch 63 formed on an outer surface of a wall 65 of the first terminal passage 4. The wall 65 may be adapted to extend into a gap formed between the locking latch 62 on one side and the support collar 40 and/or first terminal 10 on the other side, so that the locking latch 62 may slide along the outer surface of the wall 65, shown in
In order to provide sufficient space for the locking latch 62 to be elastically deflected to disengage the notch, a play 67 may be provided radially outwards from the locking latch 62 in the radial direction. The locking latch 62 may extend in the circumferential direction along an arc section, the arc section being arranged circumferentially shifted to the support collar 40.
Additionally or alternatively, the arc section, along which the locking latch 62 extends, may be radially offset from the support collar 40. Therefore, the support collar 40 does not disrupt the freedom of a deflection movement of the locking latch 62.
As can be seen in
For stabilizing the first terminal 10 within the first terminal passage 4, the first terminal passage 4 may comprise a radial constriction 68, shown in
In an embodiment, the terminal support 12 may further comprise a guiding collar 70 shown in
A gap 71 may be formed between the guiding collar 70 and the support collar 40 and/or the locking latch 62, whereby the wall 22 of the first terminal passage 4 may be received in said gap 71 essentially parallel to the longitudinal axis L of the first terminal passage 4.
In an embodiment, the front face 44 is closed between the support collar 40 and the guiding collar 70 so that the wall 22 may abut against the inner surface of the front face 44 when pushing the terminal support 12 too deep into the first terminal passage 4, as shown in
The guiding collar 70 may rest on the outer surface 20 of the wall 22, whereby the guiding collar 70 may circumferentially surround the wall 22 at least partially. Therefore, a tilting of the terminal support 12 relative to the connector housing, particularly the first terminal passage 4, may be averted.
The guiding collar 70 may comprise at least one guiding slot 72, shown in
The guiding slots 72 may further act as a polarization feature signaling the correct rotational position for mounting the terminal support 12 to the connector housing 2 and/or for mating the mating connector with the angled connector 1. In order to prevent the mating connector for being pushed too far into the first terminal passage 4 beyond the terminal support 12, the at least one guiding slot 72 may be closed at a distal end 73 directed towards the second terminal passage 6, e.g. by a bridge 74 as shown in
The angled connector 1 may be pre-assembled in the first position P, as shown in
As is shown in
The second terminal 80 may be a cable end terminal 84 being assembled onto an end of an electric cable 86, for example by crimping or the like, as shown in
According to the inventive method, the terminal support 12 is secured in the first position P shown in
Consequently, the operator may push the terminal support 12 from the first position P into the second position C pushing the connection end 38 into engagement with the second terminal 80, as is shown in
In an embodiment, the terminal support 12 may be secured in the second position C essentially parallel to the longitudinal axis L of the first terminal passage 4 in a form locking manner by having the snap nose 64 engage a second notch 63 proximal to the second terminal passage 6, as shown in
With the inventive solution, the first terminal 10 may be pre-mounted at the manufacturing site, while the second terminal 80 may be mounted on site by the operator. Therefore, the operator does not need additional equipment for processing the first terminal 10. The first terminal 10 may be mounted and secured in the first position P at the manufacturing site, wherein in the first position P, the first terminal 10 does not interfere with the second terminal 80. Thus, the operator may easily insert the second terminal 80 into the second passage 6 in the assembly position A without risking damage to any of the terminals 10, 80. Once the second terminal 80 is in the assembly position, the operator may push the terminal support 12 into the second position C, so that the first and second terminals 10, 80 may be connected to one another in a form- and/or force-locking manner.
