Description

[0001] Cross-reference to related applications

[0002] This application claims the benefit of U.S. Provisional Application No. 62 / 913,320, filed October 10, 2019. The disclosure of the application as described above is incorporated herein by reference in its entirety. Technical Field

[0003] This disclosure generally relates to a connector assembly with a connector position guarantee device, and more particularly to a connector assembly with a connector position guarantee mark. Background Technology

[0004] Automotive original equipment manufacturers (OEMs) need to implement methods to ensure that electrical connectors with wires properly align with mating connectors. To ensure proper engagement, a Connector Position Guarantee (CPA) is provided, which moves from a pre-positioned position to a mating position only when the connector and mating connector are fully in place. However, assembly operators may mate the connector but fail to move the CPA to the correct position, thus failing to ensure proper connection between the connector and mating connector. To address this issue, OEMs need a way to verify that the CPA is closed after the connection system has been engaged.

[0005] Some connector assemblies include recordable features used to record and document the presence, location, characteristics, or other features of the connector assembly during the manufacturing or assembly process to verify the correct fit of the connector assembly. Recording that the connector assembly is correctly fitted to verify that such a connection has been formed during assembly and / or verifying the presence of the connector assembly in a larger product such as an automobile or appliance being assembled can be useful. This data can then be stored in a database.

[0006] The background description mentioned herein is for the purpose of providing an overall picture of the context of this application. The work of the currently designated inventor (up to the extent described in the background section) and aspects of the specification that are not otherwise identified as prior art at the time of filing are neither explicitly nor implicitly acknowledged as prior art to this application. Summary of the Invention

[0007] According to one aspect of this disclosure, a connector is proposed. In one exemplary embodiment, the connector includes: a connector body having a mating interface configured to engage complementary mating connectors during mating operation; a first marking feature carried by the connector body and having a first partial visual identifier disposed on the first marking feature; and a second marking feature carried by the connector body and having a second partial visual identifier disposed on the second marking feature, wherein the first marking feature and the second marking feature move relative to each other between a separated position and an engaged position, characterized in that the first marking feature and the second marking feature form a complete visual identifier selected from a list including one-dimensional barcodes, two-dimensional barcodes, and three-dimensional barcodes only when in the engaged position, wherein the first marking feature and the second marking feature are in a separated position when the connector body is not fully engaged relative to the mating connector, and wherein the first marking feature and the second marking feature are in the engaged position in response to the connector body being fully engaged with the mating connector.

[0008] In some embodiments, a complete visual identifier identifies the connector. This complete visual identifier is machine-readable, such that a sensor can only read the complete visual identifier when the first and second marking features are in the engaged position. In some embodiments, a wall of the connector body defines the first marking feature, a first partial visual identifier is disposed on the outer surface of the wall, and the second marking feature is a connector position guarantee (CPA) device disposed on the second partial visual identifier. The connector position guarantee device is coupled to and movable relative to the wall of the connector body, and the CPA device is movable to bring the first and second marking features into the engaged position.

[0009] In some embodiments, the wall of the connector body defining the first marking feature is close to the mating interface. The CPA device is configured to engage with the mating connector, and when the connector body engages with the mating connector, the CPA device moves relative to the wall of the connector body in the engagement direction via the mating connector. The CPA device is movable to bring the first and second marking features into an engaged position when the connector body is fully engaged with the mating connector. In some embodiments, the CPA device is held in a track between two guide rails on the wall of the connector body. The CPA device includes a deflectable latch extending from a first end of the CPA device. When the connector body is not fully engaged with the mating connector, the deflectable latch engages at least one of the guide rails to restrict movement of the CPA device to the engaged position. When the connector body engages with the mating connector, the deflectable latch is configured to deflect via at least one corresponding lug of the mating connector to allow the CPA device to move relative to the guide rails to the engaged position.

[0010] In some embodiments, the CPA device and connector body include features configured to suppress movement of the CPA device relative to the connector body when the first and second marking features are in the engaged position. In some embodiments, a locking feature on the CPA device is interference-fitted with the connector body when the first and second marking features are in the engaged position. In some embodiments, the CPA device defines a pressing rib configured to suppress lateral and longitudinal movement of the CPA device relative to the connector body when the first and second marking features are in the engaged position.

[0011] According to another aspect of this disclosure, an electrical connector with a recordable position guarantee is proposed. In one exemplary embodiment, the electrical connector includes: a connector body having a mating interface configured to engage a complementary mating connector during mating operation and having a first marking feature having a first partial visual identifier disposed thereon; and a CPA device having a second marking feature having a second partial visual identifier disposed thereon, the CPA device being coupled to the connector body, the CPA device being movable relative to the connector body between a preparatory position and a working position, provided that the electrical connector is not fully engaged with the mating connector. When engaged, the CPA device is positioned in a standby position and is restricted from moving to a working position. The CPA device is configured to move from the standby position to the working position in response to the electrical connector fully engaging with the mating connector. The device is characterized in that, only when the CPA device is in the working position, a first marking feature and a second marking feature form a complete visual identifier selected from a list including one-dimensional barcodes, two-dimensional barcodes, and three-dimensional barcodes. The CPA device is in the standby position when the connector body is not fully engaged with the mating connector, and the CPA device is in the working position in response to the connector body fully engaging with the mating connector.

[0012] In some embodiments, a complete visual identifier identifies the electrical connector. This complete visual identifier is machine-readable, allowing the sensor to read it only when the CPA device is in the operating position. In some embodiments, the CPA device is held in a trajectory between two guide rails on the wall of the connector body. The CPA device includes a deflectable latch extending from a first end of the CPA device. When the connector body is not fully engaged with the mating connector, the deflectable latch engages at least one of the guide rails to restrict movement of the CPA device to the operating position. When the connector body engages with the mating connector, the deflectable latch is configured to deflect via at least one corresponding lug of the mating connector to allow movement of the CPA device relative to the guide rails to the operating position.

[0013] In some embodiments, the CPA device and the connector body include features configured to suppress movement of the CPA device relative to the connector body when the CPA device is in the operating position. In some embodiments, a locking feature on the CPA device interferes with the connector body when the CPA device is in the operating position. In some embodiments, the CPA device defines a pressing rib configured to suppress lateral and longitudinal movement of the CPA device relative to the connector body when the CPA device is in the operating position.

[0014] According to another aspect of this disclosure, a method for mates a connector with a complementary mating connector is proposed. In one exemplary embodiment, the method includes: providing a connector comprising: a connector body having a mating interface configured to engage complementary mating connectors during mating operation; a first marking feature carried by the connector body and having a first partial visual identifier disposed on the first marking feature; and a second marking feature carried by the connector body and having a second partial visual identifier disposed on the second marking feature, wherein the first marking feature and the second marking feature move relative to each other between a separated position and an engaged position, characterized in that the first marking feature and the second marking feature form a complete visual identifier selected from a list including one-dimensional barcodes, two-dimensional barcodes, and three-dimensional barcodes only when in the engaged position, wherein the first marking feature and the second marking feature are in a separated position when the connector body is not fully engaged relative to the mating connector, and wherein the first marking feature and the second marking feature are in an engaged position in response to the connector body being fully engaged with the mating connector; and when the connector body is fully engaged with the mating connector, the complete visual identifier is used to identify the connector when the first marking feature and the second marking feature are in the engaged position.

[0015] In some embodiments, the identification includes machine-readable identification, such that the sensor can only read the complete visual identifier when the first and second marking features are in the engaged position. In some embodiments, a wall of the connector body defines the first marking feature, the first partial visual identifier being disposed on the outer surface of the wall, the second marking feature being a CPA device disposed with a second partial visual identifier, the second partial visual identifier being coupled to and movable relative to the wall of the connector body, and the method further includes moving the CPA device during mating operation to bring the first and second marking features into the engaged position.

[0016] In some embodiments, the wall of the connector body defining the first marking feature is close to the mating interface, the CPA device is configured to engage with the mating connector, and when the connector body engages with the mating connector, the CPA device moves relative to the wall of the connector body in the engagement direction via the mating connector, and when the connector body engages fully with the mating connector, the CPA device can move to bring the first marking feature and the second marking feature into the engagement position.

[0017] In some embodiments, the CPA device is held in a trajectory between two guide rails on the wall of the connector body. The CPA device includes a deflectable latch extending from a first end of the CPA device. When the connector body is not fully engaged with the mating connector, the deflectable latch engages at least one of the guide rails to restrict movement of the CPA device to the engaged position. When the connector body engages with the mating connector, the deflectable latch is configured to deflect via at least one corresponding lug of the mating connector to allow movement of the CPA device relative to the guide rails to the engaged position. In some embodiments, the CPA device and the connector body include features configured to suppress movement of the CPA device relative to the connector body when the first and second marking features are in the engaged position.

[0029] Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. Numerous specific details are set forth in the following detailed description to provide a thorough understanding of the various described embodiments. However, it will be apparent to those skilled in the art that the various described embodiments can be practiced without these specific details. In other instances, well-known methods, processes, components, circuits, and networks have not been described in detail to avoid unnecessarily obscuring aspects of the embodiments.

[0030] Figures 1 to 8 An exemplary embodiment of an electrical connection assembly (hereinafter referred to as assembly 10) is shown. Figure 1 As shown, component 10 includes: a first connector 12 having a connector body 14; a connector position guarantee (CPA) device 16; a terminal retainer 18 configured to secure electrical terminals (not shown) within the connector body 14; and a complementary second connector 20 including mating electrical terminals (not shown). In this example, the first connector 12 also includes a seal 22 for sealing the first connector 12 to the second connector 20 to prevent environmental contaminants from entering the interface between the connectors.

[0031] The first and second connectors are configured to mate with each other during the manufacturing or assembly process. Recording the mate of the first and second connectors is useful, such as for tracking progress during the manufacturing or assembly process, and for verifying whether any problems or issues arise later regarding the correct mate of the first and second connectors. In this example, the first connector 12 includes a first marking feature 24 carried by a connector body 14, the connector body 14 having a first partial visual identifier 26 (e.g., ...) disposed on the connector body 14. Figure 3 (As shown). The first connector 12 also includes a second marking feature 28 carried by the connector body 14. In this example, the second marking feature 28 is disposed on the CPA device 16, which has a second partial visual identifier 30 disposed on the CPA device 16 (e.g., Figure 3 (As shown). As used herein, the corresponding feature “carried by the connector body” means that the feature is a component of the connector body 14, disposed on, within, or through the connector body 14; or directly or indirectly connected to the connector body 14 such that movement of the connector body 14 will also cause the “carried” feature to move.

[0032] like Figure 2 and Figure 4 As shown, the first marking feature 24 and the second marking feature 28 move relative to each other between the separated position 31 when the CPA device 16 is in its operating position 32 and the engaged position 34 when the CPA device 16 is in its operating position 36. When the first marking feature 24 and the second marking feature 28 are in the engaged position 34, and when the first partial visual identifier 26 and the second partial visual identifier 30 are adjacent to each other, the first marking feature 24 and the second marking feature 28 form a complete visual identifier 38.

[0033] The complete visual identifier 38 is associated with a corresponding first connector 12. For example, the complete visual identifier 38 may identify the first connector 12 via a part number, etc. The complete visual identifier 38 may also be associated with a second connector 20, such as by identifying the first connector 12 to which it is configured to mate, or by identifying a broader electrical connection system. The complete visual identifier 38 may also be associated with a larger machine or device, to which the first connector 12 is a component, such as a particular type or model of automobile or appliance. Alternatively, the complete visual identifier 38 may uniquely identify the first connector 12, for example by a serial number of the first connector 12 or the vehicle identification number (VIN) of the automobile to which the first connector 12 is assembled.

[0034] The complete visual identifier 38 can be a machine-readable one-dimensional barcode, two-dimensional barcode, or three-dimensional barcode. It can also be a human- or machine-readable alphanumeric or symbolic mark.

[0035] When the first connector 12 is not fully engaged with the second connector 20, the first marking feature 24 and the second marking feature 28 are in the separated position 31; when the first connector 12 and the second connector 20 are fully engaged, the first marking feature 24 and the second marking feature 28 are in the engaged position 34. The first partial visual identifier 26 and the second partial visual identifier 30 do not provide machine-readable barcodes or complete alphanumeric or symbol markings before they are adjacent to each other to form a complete visual identifier 38.

[0036] The complete visual identifier 38 is machine-readable, such that the sensor can only read the complete visual identifier 38 when the first marker feature 24 and the second marker feature 28 are in the engaged position 34. When the first marker feature 24 and the second marker feature 28 are in the disengaged position 31, the sensor may not be able to correctly read the first partial visual identifier 26 and the second partial visual identifier 30.

[0037] The sensor may be a handheld or mounted barcode scanner. The sensor may include a light source and a photodetector to read the complete visual identifier 38. Optionally, the sensor may include a digital camera. The sensor may be communicatively coupled to a database, such that data acquired by the sensor is transferred to the database for storage. The database may reside on a tangible and non-transitory computer-readable storage device. The storage device may be computer memory, such as random access memory (RAM) or a hard disk drive, or it may be a removable storage drive, such as a solid-state device, optical disk drive, external hard disk drive, flash drive, etc. The database may be remotely accessible from the sensor and may be accessed at subsequent times to access information about the connector assembly 10 and / or the vehicle, appliance, or other machine or device on which the connector assembly 10 is mounted. For example, by recording the information in the complete visual identifier 38 contained in the database, the database may be accessed remotely and / or at subsequent dates and times to verify that the first connector 12 has correctly mated to the second connector 20.

[0038] like Figures 2 to 5As shown, the wall of the connector body 14 of the first connector 12 defines a first marking feature 24. A first partial visual identifier 26 is located on the outer surface of the wall. A second marking feature 28 is located on the CPA device 16, on which a second partial visual identifier 30 is disposed. The first marking feature 24 and the second marking feature 28 may be directly printed, sprayed, etched, or otherwise formed on the connector body 14 or the CPA device 16. Alternatively, the first marking feature 24 and the second marking feature 28 may be formed on an adhesive, film, etc., and subsequently bonded or otherwise attached to the connector body 14 or the CPA device 16. The CPA device 16 is coupled to the wall of the connector body 14 and is movable relative to the wall. When the CPA device 16 moves from the preparatory position 32 to the working position 36, the CPA device 16 is movable to rotate the first marking feature 24 and the second marking feature 28 from the disengaged position 31 to the engaged position 34.

[0039] The wall of the connector body 14 defining the first marking feature 24 is close to the mating interface. When the first connector 12 mates with the second connector 20, the CPA device 16 is configured to engage the second connector 20, and is configured to move the second connector 20 in the engagement direction relative to the wall of the connector body 14, such that when the first connector 12 and the second connector 20 are fully engaged, the CPA device 16 places the first marking feature 24 and the second marking feature 28 in the engagement position 34.

[0040] CPA device 16 is held in a track between two guide rails 42 on the wall of connector body 14. CPA device 16 includes a deflectable latch extending from a first end of CPA device 16. When the first connector 12 is not fully engaged with the second connector 20, the deflectable latch engages at least one of the guide rails 42 to restrict movement of CPA device 16 to a preparatory position 32. The deflectable latch is configured to deflect by a corresponding lug of the second connector 20 when the first connector 12 engages with the second connector 20 to allow CPA device 16 to move relative to the guide rails 42 to a working position 36.

[0041] As shown in Figures 7A and 7B, when the first marking feature 24 and the second marking feature 28 are in the engagement position 34, the locking device 40 on the CPA device 16 is in interference fit with the guide rail 42 on the connector body 14. Figure 8 As shown, the CPA device 16 defines a pressing rib, which is configured to suppress lateral and longitudinal movement of the CPA device 16 relative to the connector body 14 when the first marking feature 24 and the second marking feature 28 are in the engagement position 34.

[0042] Although the illustrated embodiment has a linear CPA device 16, other embodiments of the present disclosure are conceivable, wherein the first connector includes a lever device that cooperates with the second connector, and the first and second marking features may be disposed on the lever, and the CPA device may be disposed on the lever device.

[0043] Additionally, although the exemplary implementation is an electrical connector, other implementations suitable for use with fiber optic cables, pneumatic tubes, hydraulic tubes, or hybrid connector assemblies including two or more of the items listed above are conceivable.

[0044] Therefore, a connector assembly 10 with a connector position assurance mark is provided. The marking feature 38, for example, two separate portions 24, 28 of a machine-readable barcode, is disposed on several parts 14, 16 of the connector 12, said parts being separated by a gap until the connector 12 properly engages with the mating connector 20. When the connector is properly engaged, the gap closes, and the barcode can be correctly read by a sensor such as a barcode scanner.

[0045] The marking feature is always visible, and there is no need to cover or hide any part of the marking feature. This provides flexibility in the location of the marking component on the connector assembly. The marking feature can be located on any movable feature on the connector assembly, and is not limited to the CPA device connector body assembly.
