Description

TECHNICAL FIELD The present disclosure relates to the area of electrical connectors. Particularly, the present disclosure relates to a connector, to a connector assembly comprising a connector and to a vehicle.
BACKGROUND ln a vehicle there is a large number of electrical connections between different systems and components of the vehicle. The progress within the area of electric driven vehicles during the recent years has resulted in an increase of the number of electrical connections inside electric vehicles. Further, the progress has resulted in improvements in the area of charging of vehicles where an electrical connection is needed as well. The process of assembling systems and components in a vehicle with electrical connectors is time consuming. Therefore, efforts have been made to develop solutions for automatic assembling of electrical connectors. Efforts have also been made to develop systems for automatic charging of electric vehicles. Despite progress within the area there is often a need of human intervention when assembling electrical connectors or when charging a vehicle.
Thus, to enable autonomous systems that can be operated by robots there is a need of improvements within the area of electrical connectors.
SUMMARY lt is an object of the present disclosure to overcome, or at least alleviate, at least some of the above-mentioned drawbacks and problems.
According to a first aspect of the disclosure, the object is achieved by a connector according to the independent claim related to a connector. Thus, the object is achieved by connector arranged for an electrical connection in a vehicle. The electrical connection means an electrical connection between electrical components in the vehicle or for charging of the vehicle.
The connector comprises: - a casing part configured to form a cavity within the casing part and having a through opening enabling an access into the cavity from the outside of the casing part and- a floating part comprising a first part arranged within the cavity and a second part connected to the first part and arranged for extending at least partly through the through opening of the casing part.
The casing part is arranged to accommodate the floating part such that the first part of the floating part is positioned in the cavity and the second part of the floating part extends at least partly through the through opening of the casing part. The second part extends from the first part in a direction towards the through opening and possibly through the through opening towards the outside of the casing part. The through opening of the casing part is made in a wall of the casing part to enable an access into the cavity from the outside of the casing part through the through opening. For example, the second part of the floating part can be arranged to extend partly through the through opening or can be arranged to extend through the through opening and a portion out of the casing part.
The floating part comprises a through hole for an electric line to be led through the through hole and to be connected to an electrical joint arranged at an outer surface of the casing part. The electric line may comprise several sub lines. Thus, the electric line is partly protected by the floating part.
The first part of the floating part is arranged in relation to the cavity such that there is a first space between an outer edge surface of the first part and an inner surface of the cavity radially in relation to a center axis of the casing part and wherein the second part of the floating part is arranged in relation to the through opening such that there is a second space between an outer surface of the second part and an inner surface of the through opening radially in relation to the center axis to enable a movement of the floating part in relation to the casing part in a plane extending through the first part.
Because there is the first space between the outer edge surface of the first part and the inner surface of the cavity radially in relation to the center axis of the casing part the first part can move freely within the cavity in different directions in the plane extending through the first part. The size of the first space. i.e. the distance between the outer edge surface of the first part and the inner surface of the cavity measured radially in relation to the center axis defines the distance from the center axis of the casing part that the first part can move within the cavity in the plane through the first part. Further, because there is a second space between the outer surface of the second part and an inner surface of the through opening radially in relation to the center axis the second part can move within the through opening. The size of the second space, i. e. the distance between the outer surface of the second part and theinner surface of the through opening measured radially in relation to the center axis defines the distance from the center axis that the second part can move within the through opening. Preferably, the first space and the second space are equal measured radially from the center axis. Further, because the first part and the second part are connected to each other the entire f|oating part can move in relation to the casing part in the plane extending through the first part. Preferably, the f|oating part is a one-piece f|oating part comprising the first part and the second part. The relative movement in the plane through the first part between the f|oating part and the casing part imp|ies that the f|oating part can move relatively the casing part in any directions in the plane inclusive a rotational direction. Thus, the f|oating part and the casing part can move in any direction within the plane in relation to each other inclusive a rotational movement in relation to each other.
Because the f|oating part can move freely in relation to the casing part, which imp|ies that the casing part can also move freely in relation to the f|oating part, some deviation in the position of the connector in relation to a connector receiver can be corrected during connecting of the connector to the connector receiver. Usually, the f|oating part is connected to connection part of a mounting system or a charging system, such as a robot arm. During connection of the connector to the connector receiver, when the casing part is to be positioned in a desired position in the receiving part for connection of the connector to the connector receiver, the deviation can be corrected because the casing part can move in relation to the f|oating part and can be positioned in the desired position in the connector receiver. Thereby, connection process is facilitated and human interventions can be reduced or eliminated. Thus, the connection process can be performed fully automatically. Thereby, the above-mentioned object is achieved.
Optionally, the first part is arranged in relation to the cavity such as there is a third space between an outer side surface of the first part and the inner surface of the cavity axially in relation to the center axis to enable the f|oating part to move in relation to the casing part axially along the center axis. Thus, some further deviation in the position of the connector in relation to a connector receiver can be corrected during connecting of the connector to the connector receiver. Thereby, connection process is yet facilitated.
Optionally, the casing part and the f|oating part have a cylindrical shape and the cavity and the through opening have circular cross-sectional shapes. Thus, the first space and the second space may have circular shapes.Optionally, the cavity and the through opening are centered in relation to the center axis of the casing part. Thus, manufacturing of the connector can be Simplified. As a further effect, the correction of the deviations in the position of the connector in relation to a connector receiver can be facilitated.
Optionally, the outer surface of the casing part which is provided with the electrical joint is angled in relation to the center axis with a first angle. Thus, the casing part is tapered in a direction towards a virtual point on the center axis outside the casing part and on an opposite side of the casing part than the side with the through opening. As a result, during positioning of the connector in a connector receiver, when the casing part is to be positioned in a desired position in the connector receiver, the connection process can be yet facilitated because the casing part can be guided into the connector receiver along the angled outer surface of the tapered part of the casing part. Thus, a yet improved connector is provided.
Optionally, the connector comprises a spring arranged along the second part and arranged to bias the floating part in relation to the casing part axially along the center axis. Because the floating part is biased in relation to the casing part also the casing part will be biased towards a connector receiver after the connector has been connected to the connector receiver. Thus, an improved electrical connection is provided because of pressure forces acting on the electrical joints of the connector and the connector receiver. As a result, a yet improved connector is provided.
Optionally, the electrical joint comprises at least two metal pins. Thus, a simple electrical joint is provided.
Optionally, the metal pins have a capability of elastic deformation in a radial direction in relation to the center axis. Thus, an improved electrical connection can be provided because the metal pins can act with pressure forces on a corresponding further electrical joint of a connector receiver when the casing part has been positioned in a desired position in the connector receiver. Thereby, a yet improved connector is provided.
Optionally, the casing part comprises a locking portion arranged on an opposite side of the casing part than the side of the casing part where the through opening is arranged along the center axis. Thus, the casing part can be locked in a connector receiver and thereby the connector can be locked in the connector receiver.Optionally, the locking portion has a capability of elastic deformation in a radial direction in relation to the center axis of the casing part. Thus, the locking portion can Work according to a click in function for locking of the connector in the connector receiver. Thus, a simple and efficient locking is provided.
According to a second aspect of the disclosure, the object is achieved by a connector assembly according to the independent claim related to a connector assembly. Thus, the object is achieved by connector assembly arranged for an electrical connection in a vehicle. The connector assembly comprises a connector according to any of the embodiments described herein and a connector receiver arranged to receive the connector to achieve the electrical connection. According to some embodiments, the connector receiver can have a fast position and the connector can be movable and arranged to be connected to the connector receiver. For example, the connector receiver can be a charging contact of a vehicle and the connector can be arranged on a charging cable. Because the connector assembly comprises an improved connector which facilitates the connection process when the human interventions can be reduced or eliminated an improved connector assembly is provided. Thereby, the above-mentioned object is achieved.
Optionally, the connector receiver comprises a further electrical joint arranged to cooperate with the electrical joint of the connector for the electrical connection.
Optionally, the further electrical joint comprises at least two further metal pins. Thus, a simple further electrical joint is provided.
Optionally, an inner surface of the connector receiver is angled in relation to a further center axis of the connector receiver with a second angle corresponding to the first angle of the outer surface of the casing part of the connector. Thus, the inner portion of the connector receiver is arranged tapered in a direction towards a further virtual point on the further center axis outside the connector receiver, on the side of the connector receiver opposite to the side arranged to receive the connector and more particularly the casing part of the connector. As a result, during positioning of the connector in a connector receiver, when the casing part is to be positioned in a desired position in the connector receiver, the connection process can be yet facilitated because the casing part can be guided into the connector receiver along the tapered outer surface of the casing part and along the tapered inner surface of the connector receiver. Thus, a yet improved connector assembly is provided.Optionally, the connector receiver comprises a further locking portion arranged to cooperate with the locking portion of the casing part to lock the connector to the connector receiver. Thus, the casing part can be locked in the connector receiver which implies that the connector can be locked in the connector receiver.
The object is also achieved by a vehicle according to the independent claim related to a vehicle. Thus, the object is achieved by a vehicle comprising a connector assembly according to any of the embodiments described herein and/or comprising a connector receiver arranged to receive a connector according to any of the embodiments described herein. Because the vehicle comprises an improved connector assembly and/or an improved connector receiver enabling assembling of components in the vehicle and charging of the vehicle in an automatic manner, an improved vehicle is provided Thereby, the above- mentioned object is achieved.
Further features of, and advantages with, the present invention will become apparent when studying the appended claims and the following detailed description.
BRIEF DESCRIPTION OF THE DRAWINGS Various aspects of the invention, including its particular features and advantages, will be readily understood from the example embodiments discussed in the following detailed description and the accompanying drawings, in which: Fig. 1 illustrates a cross sectional view of a connector assembly comprising a connector and a connector receiver, wherein the connector and the connector receiver are illustrated disassembled, Fig. 2 illustrates a perspective cross sectional view the connector assembly illustrated in Fig. 1 being assembled and Fig. 3 illustrates schematically a vehicle.
DETAILED DESCRIPTION Aspects of the present invention will now be described more fully. Like numbers refer to like elements throughout. Well-known functions or constructions will not necessarily be described in detail for brevity and/or clarity.
Fig. 1 illustrates a connector assembly 37 arranged for an electrical connection in a vehicle 2. The vehicle 2 is illustrated schematically in Fig.The connector assembly 37 comprises a connector 1 and a connector receiver 39 arranged to receive the connector 1 to achieve the electrical connection.
The connector 1 comprises: - a casing part 3 configured to form a cavity 5 within the casing part 3 and having a through opening 7 enabling an access into the cavity 5 from the outside of the casing part 3 and - a f|oating part 9 comprising a first part 9.1 arranged within said cavity 5 and a second part 9.2 connected to the first part 9.1 and arranged for extending at least partly through said through opening 7 of the casing part The casing part 3 may be manufactured by a molding process and may be of a plastic material. Thus, the cavity 5 and the through opening 7 may be created during molding of the casing part 3. As an alternative, the through opening 7 may be created after a molding process of the casing part 3, for example by drilling.
The f|oating part 9 comprises a through hole 11 for an electric line to be led through the through hole 11 and to be connected to an electrical joint 13 arranged at an outer surface 15 of the casing part 3. The outer surface 15 provided with the electrical joint 13 is a side surface of a part of the casing part 3 that is configured to be inserted into a connector receiver 39. The electric line may comprise several sub electric lines and is a standard solution within electrical connections and is therefore not described in details herein.
The first part 9.1 of the f|oating part 9 is arranged in relation to the cavity 5 such that there is a first space 17 between an outer edge surface 19 of the first part 9.1 and an inner surface 21 of the cavity 5 radially in relation to a center axis a1 of the casing part The second part 9.2 of the f|oating part 9 is arranged in relation to the through opening 7 such that there is a second space 23 between an outer surface 25 of the second part 9.2 and an inner surface 27 of the through opening 7 radially in relation to the center axis a1 to enable a movement of the f|oating part 9 in relation to the casing part 3 in a plane p extending through the first part 9.
Preferably, the f|oating part 9 is a one-piece f|oating part 9 comprising the first part 9.1 and the second part 9.2. The f|oating part 9 may be manufactured by molding and may be of a plastic material.According to the embodiments illustrated in Fig. 1, the casing part 3 and the floating part 9 have a cylindrical shape and the cavity 5 and the through opening 7 have circular cross- sectional shapes. Thus, the first part 9.1 and the second part 9.2 of the floating part 9 have cylindrical shape. The first part 9.1 have a shape of a flat cylinder having a first diameter d1. The second part 9.2 have a shape of an elongated cylinder having a second diameter d2. Further, the second part 9.2 extends substantially perpendicularly from the first part 9.1 and through the through opening 7 and outside the casing part The cavity 5 has a third diameter d3, wherein the third diameter d3 is greater than the first diameter d1 of the first part 9.1 of the floating part 9. The through opening 7 has a fourth diameter d4, wherein the fourth diameter d4 is greater than the second diameter d2 of the second part 9.2 of the floating part 9. Thus, the first space 17 in the cavity 5 is created because of the difference between the third diameter d3 and the first diameter d1. ln a similar way, the second space 23 is created because of the difference between the fourth diameter d4 and the second diameter d2. The size of the first space 17 and of the second space 23 radially in relation to the center axis a1 determines how much, i.e. to which extend, the floating part 9 can move in relation to the casing part 3 along the plane p. The ratios between the third diameter d3 and the first diameter d1 and between the fourth diameter d4 and the second diameter d2 can be freely chosen with retained intended functionality of the connector 1 regarding the movement of the floating part 9 along the plane p in relation to the casing part 3. However, it needs to be considered that the first part 9.1 of the floating part 9 extends radially into the cavity 5, seeing in a direction from the center axis a1, and that the first diameter d1 of the first portion 9.1 is greater than the fourth diameter d4 of the through opening 7. Thereby, the floating part 9 is properly positioned in the casing part 3 and risks for an unintentional removal of the floating part 9 from the casing part 3 during use can be at least reduced.
According to the embodiments illustrated in Fig. 1, the first space 17 and the second space 23 have circular shapes. The difference between the third diameter d3 and the first diameter d1 may be equal the difference between the fourth diameter d4 and the second diameter d According to the embodiments illustrated in Fig. 1, the cavity 5 and the through opening 7 are centered in relation to the center axis a1 of the casing part 3. Thus, the center axis a1 is the common axis for the cavity 5 and for the through opening The first part 9.1 can be arranged in relation to the cavity 5 such as there is a third spacebetween an outer side surface 31 of the first part 9.1 and the inner surface 21 of the cavityaxially in relation to the center axis a1 to enable the floating part 9 to move in relation to the casing part 3 axially along the center axis a1. As illustrated in Fig. 1, the first part 9.1 of the floating part 9 has a first thickness t1 and the cavity 5 has a second thickness t2, wherein the second thickness t2 is greater than the first thickness t1. Thus, the third space 29 is created because the difference between the second thickness t2 and the first thickness t1. For example, the first thickness t1 is between 75 and 95 % of the second thickness t2. Thus, the floating part 9 can move in relation to the casing part 3 axially along the center axis a1 and still being positioned in casing part 3 such that risks for the first part 9.1 get stuck in the cavity 5 can be at least reduced.
The outer surface 15 of the casing part 3 which is provided with the electrical joint 13 is angled in relation to the center axis a1 with a first angle 0:1. For example, the first angle 0:1 is in a range between 15 and 50 degrees. Thus, the casing part 3 is tapered in a direction towards a virtual point (not shown) on the center axis a1 outside the casing part and on an opposite side of the casing part 3 than the side of the casing part with the through opening.
The connector 1 may comprise a spring 33 arranged along the second part 9.2 and arranged to bias the floating part 9 in relation to the casing part 3 axially along the center axis a1. The spring 33 is arranged along the outer surface 25 of the second part 9.2 and is arranged to bias a connection part (not shown) connected to the second part 9.2 of the floating part According to the embodiments illustrated in Fig. 1, the electrical joint 13 comprises two metal pins 13. Each of the at least two metal pins 13 have a capability of elastic deformation in a radial direction in relation to the center axis a1. Thus, after the connector 1 has been inserted into a connector receiver 39 an improved electrical connection is achieved because the metal pins 13 are then pressed radially towards the center axis a1 which implies that pressure forces will then act on the metal pins 13 radially in a direction from the center axis a The casing part 3 comprises a locking portion 35 arranged on an opposite side of the casing part 3 than the side of the casing part 3 where the through opening 7 is arranged along the center axis a1. Thus, the connector 1 can be locked by means of the locking portion.
The locking portion 35 has a capability of elastic deformation in a radial direction in relation to the center axis a1 of the casing part 3. Thus, the locking portion 35 can work according to a click in function for locking of the connector 1 in the connector receiver 39. Thus, a simple and efficient locking is provided.
The connector receiver 39 comprises a further electrical joint 41 arranged to cooperate with the electrical joint 13 of the connector 1 for said electrical connection. According to the embodiments illustrated in Fig. 1, the further electrical joint 41 comprises at least two further metal pins 41. Each of the at least two further metal pins 41 may have a capability of elastic deformation in a radial direction in relation to the further center axis a2 in a similar manner as the metal pins 13 of the connector An inner surface 43 of the connector receiver 39 is angled in relation to a further center axis a2 of the connector receiver 39 with a second angle 0:2 corresponding to the first angle 0:1 of the outer surface of the casing part 3 of the connector 1. Thus, the second angle 0:2 may be in a range between 15 and 50 degrees. Consequently, the casing part 3 is tapered. Thus, the inner portion of the connector receiver 39 is arranged tapered in a direction towards a further virtual point (not shown) on the further center axis a2 outside the connector receiver 39, on the side of the connector receiver 39 opposite to the side arranged to receive the connectorand more particularly the casing part 3 of the connector The connector receiver 39 comprises a further locking portion 45 arranged to cooperate with the locking portion 35 of the casing part 3 to lock the connector 1 to the connector receiver 39. Thus, the connector 1 can be locked in the connector receiver Fig. 2 illustrates a perspective cross sectional view the connector assembly 37 illustrated in Fig. 1 being assembled. As can be seen, the connector 1 has been connected to the connector receiver 39 by the casing part 3 being inserted into the connector receiver 39 and being locked in the connector receiver 39 by a cooperation between the locking portion 35 and the further locking portion 45. As illustrated in Fig. 2, the locking portion 35 may comprise two sub locking portions and the further locking portion can be arranges as an opening in the bottom of the connector receiver 39 arranged to receive the sub locking portions. The sub locking portions are arranged to be pressed together when inserted in the opening and revert to the initial position after being inserted. Protrusions at the end of the sub locking portions result in locking of the casing part 3 to the connector receiver Because of the functionality of the connector 1 regarding the movement of the floating part 9 along the plane p in relation to the casing part 3 as described in conjunction to Fig. 1, any deviations in position of the connector 1 in relation to the connector receiver 39 before the connection has been corrected and the connector 1 has been connected to the connector receiver 39 such that the further center axis a2 of the connector receiver 39 coincides the center axis a1 of the casing part 3 of the connectorFig. 3 illustrates schematically a vehicle 2. The vehicle 2 may comprise a connector assembly 37 according to any of the embodiments described herein and/or may comprise a connector receiver 39 arranged to receive a connector 1 according to any of the embodiments described herein. ln Fig. 3 it is illustrated schematically that the vehicle 2 comprises a connector receiver 39 arranged for charging of the vehicle 2. The position of the connector receiver 39 on the vehicle 2 illustrated in Fig. 3 is only an example of a possible position. Other positions are also possible with consideration regarding, for example, easy access for an operator.
