Description

1. Field of the invention

[0001] This invention relates to a right-angled connector, and a method of assembling such a connector.2. Background

[0002] The technical background of the invention relates to electrical connectors, specifically right-angled connectors used in systems where space constraints, mechanical stability, and reliable electrical connections are critical, such as in automotive applications. Right-angled connectors are designed to allow electrical terminals and conductors to interface at a go-degree angle, optimizing the use of space and facilitating routing in tight environments.

[0003] The problem addressed by the invention revolves around ensuring the stable and secure retention of right-angled terminals within the connector housing, preventing displacement or misalignment during assembly, operation, or exposure to external forces like vibrations. Traditional connectors may struggle with terminal movement, especially in demanding conditions, leading to poor electrical contact, increased wear, and failure.

[0004] In view of the foregoing, there is a need for an improved right-angled connector. It is thus an object of the present invention to overcome some or all the deficiencies of the prior art.3. Summary

[0005] The above objects are at least partially solved by the subject matter of independent claim 1. Preferred embodiments are the subject of the dependent claims, and the skilled person will find clues to other suitable aspects of the present invention in the overall disclosure of the present application.

[0006] An aspect of the invention relates to a right-angled connector, comprising: a connector housing having a rearward stop surface, the rearward stop surface configured to maintain at least one right-angled terminal within a terminal cavity in the connector housing against a movement in unmating direction, the right-angled terminal having a connection section configured to interface with a corresponding terminal along a connection axis and an attachment section configured to be attached to a conductor; and a retainer, attachable to the connector housing, the retainer being configured to enclose the terminal cavity and defining a forward stop surface configured to retain the right-angled terminal within the terminal cavity to block a movement of the terminal relative to the housing in mating direction.

[0007] Such a connector has a connector housing that has a rearward stop surface designed to hold a right-angled terminal securely inside a cavity within the housing, preventing it from moving backward against mating direction. The right-angled terminal itself has two important sections: a connection section that interfaces with another terminal along a specific axis and an attachment section that connects to a conductor, such as a wire. Additionally, the connector features a retainer that can be attached to the housing. The retainer encloses the terminal cavity and includes a forward stop surface, which holds the terminal in place, preventing it from moving forward in the mating direction. The right-angled configuration of the terminal allows for more efficient use of space within tight environments. The rearward and forward stop surfaces ensure that the terminal remains fixed during both connection and disconnection, reducing wear and the risk of failure. Thus, the terms rearward and forward in this context describe a direction in relation with the mating direction. Forward means "in mating direction" and rearward means "against the mating direction" (i.e., in unmating direction).

[0008] This can be improved when the terminal is engaged with a first latching means of the connector housing, such that the movement of the terminal relative to the housing is blocked in a direction perpendicular to the mating direction.

[0009] Such a feature could be particularly useful in environments where the connector might be subjected to external forces or vibrations. The first latching mechanism provides an extra layer of stability, preventing the terminal from loosening or shifting out of alignment. This improved alignment enhances the electrical connection's reliability and longevity, reducing the risk of connection failure due to misalignment or wear.

[0010] Further improvement is achieved when the connector housing comprises a mating section, adapted to circumferentially receive the connection section of the terminal, preferably forming a round shaped hollow cylinder.

[0011] Such a mating section could be utilized in applications where a secure and precise fit is important, such as in high-frequency data or signal transmission. The circumferential engagement of the terminal improves the connection's stability by evenly distributing mechanical forces around the terminal, preventing it from shifting or loosening.

[0012] This embodiment can be further improved when the mating section forms a first round shaped hollow cylindrical segment, wherein the arc angle Θ of the segment is between 180 and 270 degree, preferably between 210 and 240 degree and most preferably 225 degree.

[0013] Such a cylindrical segment could be used in applications where space constraints or the need for easier assembly and disassembly are critical. The partial cylindrical segment allows the terminal to be securely held in place while also enabling easier insertion and removal of the retainer. The specific arc angle ensures that there is enough enclosure to provide a strong mechanical hold on the terminal while leaving an open section that facilitates access for installation of the retainer and / or the terminal itself.

[0014] This can be further improved when the retainer comprises a second round shaped hollow cylindrical segment, adapted to form a closed hollow cylinder with the first second round shaped hollow cylindrical segment in mounted condition.

[0015] Such a retainer could be beneficial in environments where a completely enclosed terminal is necessary for protection against external factors, such as dust, moisture, or mechanical impact. By forming a closed cylinder around the terminal, the connector ensures that the terminal remains firmly in place while providing additional shielding from environmental influence.

[0016] Further improvement can be achieved when the retainer comprises a cavity, adapted to hold a terminal and wherein the retainer further comprises a fastener, configured to releasably retain the terminal in the retainer.

[0017] Such a retainer could be useful in applications requiring maintenance or replacement of terminals. The releasable fastener ensures that the terminal is held securely during operation but allows for easy disconnection when needed, thus simplifying repair or upgrades.

[0018] This can be further improved when the fastener is attached to the retainer by means of a film hinge.

[0019] Such a film hinge could be beneficial in applications requiring frequent adjustments or reconnections. The flexible hinge allows for easy manipulation of the fastener without the risk of losing separate components, thus simplifying assembly and maintenance processes. The film hinge also reduces the likelihood of mechanical failure by minimizing the number of discrete parts.

[0020] This can be further improved when the fastener is adapted to retain at least one terminal inside the retainer by closing the fastener and to retain another terminal, that is arranged in the connector housing, when the retainer is mounted to the connector housing.

[0021] Such a fastener could be advantageous in complex systems where multiple terminals need to be connected and secured at once. The ability of the fastener to retain multiple terminals ensures a strong and reliable connection. Such a connector also simplifies assembly and reduces the number of individual components, enhancing both the efficiency and reliability of the connector.

[0022] This can be further improved when the retainer comprises a retainer connection section, adapted to receive the connection section of the terminal and a retainer attachment section, adapted to receive the attachment section of the terminal, and wherein retainer connection section and the retainer attachment section are arranged at 90° with respect to each other.

[0023] Such a configuration would be particularly useful in space-constrained environments where compact and efficient routing of conductors is essential. The 90-degree arrangement allows for optimized use of space, thus ensuring that the connection and attachment sections are securely held while maintaining the necessary right-angle configuration. This design also enhances the stability and performance of the connector by providing dedicated sections for both the electrical connection and mechanical attachment points, thus ensuring reliable and robust operation.

[0024] This can be further improved when the retainer is adapted to retain at least one terminal and the housing is adapted to hold at least one other terminal and the fastener is arranged between the terminal inside the retainer and the terminal in the housing in mounted condition of housing and retainer.

[0025] Such a design can be effective in multi-terminal connectors. By positioning the fastener between the terminals in both the retainer and housing, the design ensures that all terminals are properly aligned and securely fastened in one step. This simplifies the assembly process, reduces the risk of terminal displacement during use, and ensures consistent electrical contact, even in demanding environments subject to vibration or movement or the like.

[0026] Further improvement can be achieved when the retainer is attachable to the housing by moving the retainer against the mating direction.

[0027] Such a retainer is useful in scenarios where space constraints or ease of assembly are important. By allowing the retainer to be attached from the direction opposite to the mating direction of the connector, the design simplifies installation and provides better access to the terminals during assembly or maintenance.

[0028] Further improvement can be achieved when the housing has a right-angled configuration with a mating section, adapted to be circumferentially around the connection section of the terminal in mounted condition, and a main section adapted to receive the attachment section of the terminal in mounted condition.

[0029] Such a right-angled configuration can be useful in applications where space management is important, such as in densely packed automotive systems. The design allows for efficient routing of wires and terminals at a go-degree angle, optimizing space and improving the layout of the wiring. By securely holding both the electrical and mechanical parts of the terminal, the connector ensures a stable and reliable performance under various operating conditions.

[0030] Another aspect of the invention relates to a method of assembling a right-angled connector, comprising: inserting a right-angled terminal configured to be attached to a conductor into a terminal cavity of a connector housing along a first insertion direction, the connector housing comprising a rearward stop surface bordering the terminal cavity; attaching a retainer configured to enclose the terminal cavity to the connector housing along a second insertion direction, the cover defining a forward stop surface configured to retain the right-angled terminal within the terminal cavity; and disposing a portion of the right-angled terminal between the rearward stop surface and the forward stop surface.

[0031] Such a method offers an efficient way to assemble right-angled connectors in environments where space is limited, such as in automotive or electronic systems. By utilizing distinct rearward and forward stop surfaces, the method ensures that the terminal is properly aligned and securely fastened within the connector housing, preventing unwanted movement during operation.

[0032] This method can be further improved when the right-angled terminal comprises a connection section configured to interface with a corresponding terminal along a connection axis and an attachment section configured to be attached to a conductor and wherein the connection axis is substantially perpendicular to the first insertion direction, wherein preferably the connection axis is substantially parallel to the second insertion direction.

[0033] Such a method is suitable for use in applications requiring precise terminal alignment. The perpendicular relationship between the connection axis and the first insertion direction ensures a compact, efficient design, while the parallel alignment with the second insertion direction simplifies assembly and enhances terminal stability. This method leads to improved electrical contact and greater mechanical integrity in space-restricted environments.

[0034] This method can be further improved when the attaching of the retainer is achieved by a first step of moving the retainer in a direction parallel to the first insertion direction and a second step of moving the retainer in a direction parallel to the second insertion direction.

[0035] Such a method provides a controlled and precise way to assemble the connector, ensuring that the retainer securely locks into place without misalignment. This method is beneficial in situations where the connector needs to withstand vibrations or mechanical stress. The two sequential steps help ensure a robust mechanical and electrical connection, thus reducing the likelihood of assembly errors.4. Brief description of the figures

[0037] The subsequent sections provide a detailed description of the invention, referencing the accompanying illustrations for clarity. The descriptions represent examples only and are not intended to limit the invention's scope. Identical reference numerals across the figures and text denote the same components. The illustrations may not reflect actual size or scale; their dimensions, proportions, and depictions of elements might be enhanced for better understanding and visual convenience.

[0038] Figure 1 illustrates a right-angled connector 1 according to the invention in a perspective view. A right-angled terminal 200 is mounted inside the connector housing 100. A retainer 300 retains the terminal 200 inside the connector housing 100 and is attached to the connector housing by the engagement of a second latching means 102 of the housing with a counter latching means 320 of the retainer. The mating section 130 circumferentially encloses, respectively receives a connection section 210 of the terminal 200 (cf. also to Fig. 4A), forming a round shaped hollow cylinder. The housing 100 has a right-angled configuration with a mating section 130, that is circumferentially around the connection section 210 of the terminal 200, and a main section 140 that encloses the attachment section 220 of the terminal 200.

[0039] Such a design ensures that the terminal is firmly retained in position while allowing for reliable electrical contact due to the round, circumferential enclosure of the connection section. This configuration is useful for maintaining a stable connection in applications subjected to physical movement or vibrations, ensuring the terminal remains properly aligned within the connector housing for consistent performance.

[0040] Figure 2 shows the retainer 300 of Figure 1 in a perspective view. The retainer 300 comprises counter latching means 320 to engage the second latching means 102 of the housing for attaching the retainer to the connector housing 100. The retainer 300 further comprises a forward stop surface 310, configured to block a movement of the terminal relative to the housing in mating direction when the retainer 300 is mounted on the housing.

[0041] Such an engagement of the counter-latching means and the forward stop surface provides a robust mechanism for securing the terminal within the connector. This dual functionality not only keeps the terminal properly aligned but also ensures that it cannot be pushed too far forward during the mating process, which is particularly important in ensuring consistent electrical performance and mechanical durability in high-vibration or dynamic environments.

[0042] Figure 3 shows the housing 100 of Figure 1 in a cross-sectional view. The housing 100 comprises the mating section 130, that is adapted for mating with a corresponding counter connector. Inside the housing, a terminal cavity 120 is provided to receive the terminal 200 therein. The housing further comprises first latching means 101, adapted to engaged with the terminal, such that a movement of the terminal relative to the housing is blocked in a direction perpendicular to the mating direction. A rearward stop surface 110 is configured to maintain the terminal withing the terminal cavity 120 against a movement in unmating direction. The terminal cavity 120 holds the terminal in mounted condition. The second latching means 102 are adapted to engage with the counter latching means of the retainer.

[0043] Such a design securely fastens the retainer to the housing, effectively locking the terminal in place between the rearward stop surface and the forward stop surface provided by the retainer, ensuring stable and reliable operation. The design allows for precise alignment and retention of the terminal within the connector, which is important for maintaining strong electrical contact and resisting external forces. The use of multiple latching mechanisms enhances both the mechanical strength and durability of the connector.

[0044] Figures 4A-4C illustrate the assembling of the connector 1 in a perspective view. In Figure 4A the right-angled terminal 200 comprises a connection section 210 configured to interface with a corresponding terminal along a connection axis and an attachment section 220 configured to be attached to a conductor 221. The mating section 130 on the housing 100 forms a first round shaped hollow cylindrical segment, wherein the arc angle Θ of the segment is about 270 degree. The Terminal 200 can be mounted in the housing by moving it in the direction of the arrow. Figure 4B depicts the terminal 200 mounted in the terminal cavity 120 of the connector housing 100. The first latching means 101 of the housing engage with the connection section 210 of the terminal and block movement of the terminal against the mounting direction of the terminal 200.

[0045] Figure 4C shows the mounting of the retainer 300 onto the housing 100 by moving the retainer against the mating direction of the connector 1 as indicated by the arrow. The retainer 300 comprises a second round shaped hollow cylindrical segment 330, adapted to form a closed hollow cylinder with the first round shaped hollow cylindrical segment 130 in mounted condition.

[0046] Such an assembly process ensures that the right-angled terminal is properly secured within the connector housing, maintaining alignment and preventing movement during operation. The 270-degree cylindrical mating section offers mechanical support to the connection section, while the latching mechanisms provide additional security, ensuring that the terminal remains securely fixed.

[0047] Figure 5 depicts another connector 5 according to the invention in a perspective view. A right-angled terminal 600 is mounted inside the connector housing 500. A retainer 700 retains the terminal 600 inside the connector housing 500 and is attached to the connector housing by the engagement of second latching means 502 of the housing with counter latching means 720 of the retainer. The mating section 530 circumferentially encloses the connection section 610 of the terminal 600, forming a round shaped hollow cylinder. One part of the mating section 530 is open, respectively forms not a full cylinder but only a cylindrical segment. The retainer 700 correspondingly comprises a second round shaped hollow cylindrical segment 730, adapted to form a closed hollow cylinder with the open part of the mating section 530. Thereby, the fully closed round shaped hollow cylindrical segment 530 is formed in mounted condition.

[0048] Such a design offers reliable mechanical and electrical stability, ensuring that the terminal is both physically protected and electrically connected. The cylindrical mating section provides robust mechanical support, reducing the risk of terminal movement or misalignment during operation.

[0049] Figure 6 shows the retainer 700 of the connector of Figure 5 in a perspective view. The retainer 700 comprises counter latching means 720 to engage the second latching means 502 of the housing. The retainer 700 further comprises a forward stop surface 710, configured to stop movement of the terminal 600 in mating direction.

[0050] Such a configuration with forward stop surface and the counter-latching mechanism working together provides a reliable retention system for the terminal. This design prevents any unwanted displacement of the terminal during connection.

[0051] Figures 7A-7C illustrate a mounting procedure of the terminal in the housing of the connector of Figure 5. The terminal 600 is inserted into the connector housing 500 in a superimposition of a rotational and translation movement until the terminal 600 engages the first latching means 501.

[0052] Such a mounting process with a combination of rotational and translational movement facilitates smoother insertion, reducing the risk of misalignment or damage to the terminal or housing.

[0053] Figures 8A-8C depict another mounting procedure of the terminal in the housing of the connector of Figure 5. The terminal 600 is inserted into the connector housing 500 in a rotational movement until the terminal 600 engages the first latching means 501.

[0054] Such a rotational mounting procedure simplifies the insertion process, allowing for precise alignment of the terminal within the housing with minimal effort. The rotational movement facilitates smoother engagement with the latching mechanism, ensuring that the terminal is properly.

[0055] Figures 9A-9C show the two-step assembly of the retainer in the housing of the connector 5 of Figure 5. In Figure 9A the retainer 700 is moved upwards in the figure, i.e. perpendicular to the mating direction in a first retainer assembly step. Figure 9B depicts a second retainer assembly step of moving the retainer 700 in the unmating direction of the connector. Figure 9C shows the mounted retainer 700 in the housing 500 with the engagement of the second latching means 502 with the counter latching means 720. The retainer 700 forms a closed hollow cylinder with the open part of the mating section 530.

[0056] Such a two-step assembly method provides a precise and controlled attachment process for the retainer, ensuring both proper alignment and secure retention. The dual-direction movements allow for smoother assembly and reduce the risk of misalignment or damage.

[0057] Figure 10 depicts another connector 10 according to the invention in a perspective view. Also in this embodiment, a retainer 1200 encloses multiple terminals 1100 and is mounted in the housing 1000.

[0058] Figure 11A-11C depicts the mounting procedure of the terminals with the retainer 1200 of the connector of Figure 10. Figure 11A shows the retainer 1200 and the terminals 1100. The retainer 1200 comprises two cavities 1201, adapted to receive the terminals 1100. The retainer 1200 further comprises a fastener 1250, configured to releasably retain the terminals 1100 in the retainer 1200. Figure 11B shows the terminals 1100 arranged inside the cavities 1201 of the retainer 1200 and the fastener 1250, which is attached to the retainer 1200 by means of a film hinge 1251. Figure 11C shows the closed fastener 1250, such that the terminals 1100 are retained in the retainer 1200. The retainer 1200 comprises a retainer connection section 1210, adapted to receive the connection section 1110 of the terminal 1100 and a retainer attachment section 1220, adapted to receive the attachment section of the terminal 1120, and wherein retainer connection section 1210 and the retainer attachment section 1220 are arranged at 90° with respect to each other.

[0059] Such a mounting procedure allows for secure and efficient retention of multiple terminals within the retainer. The use of the film hinge simplifies the closing mechanism by keeping the fastener attached to the retainer, reducing the risk of losing parts during assembly. This design is beneficial in applications where multiple terminals need to be retained securely, ensuring reliable connections and easy assembly or maintenance. The fastener's releasable feature also allows for convenient removal or replacement of terminals when necessary.

[0060] Figure 12 shows the mounting procedure of two terminals 1100 in the housing 1000 of the connector of Figure 10. The terminals 1100 are moved in the terminal mounting direction, until the terminals are mounted in the housing 1000 by engaging with the first latching means 1001.

[0061] Figure 13A-13B depict the mounting procedure of the retainer in the housing of the connector of Figure 10 and 12. In Figure 13A, the housing 1000 holds the two mounted terminals 1100, while the retainer 1200 holds two additional terminals 1100'. Figure 13B shows the mounted retainer 1200 on the housing 1000, thus forming a connector 10 with four terminals. The retainer 1200 is attachable to the housing by moving the retainer against the mating direction of the connector. The fastener 1250 retains the two terminals 1100' inside the retainer 1200 and it also retains the two other terminals 1100, that are pre-mounted in the connector housing, when the retainer (1200) is mounted to the connector housing as shown in Fig. 13B. As one can take from the figure, the retainer 1200 is adapted to retain two terminals and the housing is adapted to hold two other / additional terminals. In mounted condition of housing and retainer, the fastener 1250 is arranged between the terminals inside the retainer and the terminals in the housing. The retainer 1200 is attachable to the housing by moving the retainer 1200 against the mating direction, as mounting guides 1300 attached on two sides of the retainer allow movement only against mating direction.

[0062] Such a design allows for the combination of terminals from both the housing and the retainer, providing a compact and efficient solution for multi-terminal connections. The secure retention of the terminals through both the housing and the retainer ensures reliable electrical contact and mechanical stability. The design also facilitates modular assembly, enabling easy maintenance or replacement of individual components without compromising the entire connector's integrity.References:

1. Field of the invention

[0001] This invention relates to a right-angled connector, and a method of assembling such a connector.2. Background

[0002] The technical background of the invention relates to electrical connectors, specifically right-angled connectors used in systems where space constraints, mechanical stability, and reliable electrical connections are critical, such as in automotive applications. Right-angled connectors are designed to allow electrical terminals and conductors to interface at a go-degree angle, optimizing the use of space and facilitating routing in tight environments.

[0003] The problem addressed by the invention revolves around ensuring the stable and secure retention of right-angled terminals within the connector housing, preventing displacement or misalignment during assembly, operation, or exposure to external forces like vibrations. Traditional connectors may struggle with terminal movement, especially in demanding conditions, leading to poor electrical contact, increased wear, and failure.

[0004] In view of the foregoing, there is a need for an improved right-angled connector. It is thus an object of the present invention to overcome some or all the deficiencies of the prior art.3. Summary

[0005] The above objects are at least partially solved by the subject matter of independent claim 1. Preferred embodiments are the subject of the dependent claims, and the skilled person will find clues to other suitable aspects of the present invention in the overall disclosure of the present application.

[0006] An aspect of the invention relates to a right-angled connector, comprising: a connector housing having a rearward stop surface, the rearward stop surface configured to maintain at least one right-angled terminal within a terminal cavity in the connector housing against a movement in unmating direction, the right-angled terminal having a connection section configured to interface with a corresponding terminal along a connection axis and an attachment section configured to be attached to a conductor; and a retainer, attachable to the connector housing, the retainer being configured to enclose the terminal cavity and defining a forward stop surface configured to retain the right-angled terminal within the terminal cavity to block a movement of the terminal relative to the housing in mating direction.

[0007] Such a connector has a connector housing that has a rearward stop surface designed to hold a right-angled terminal securely inside a cavity within the housing, preventing it from moving backward against mating direction. The right-angled terminal itself has two important sections: a connection section that interfaces with another terminal along a specific axis and an attachment section that connects to a conductor, such as a wire. Additionally, the connector features a retainer that can be attached to the housing. The retainer encloses the terminal cavity and includes a forward stop surface, which holds the terminal in place, preventing it from moving forward in the mating direction. The right-angled configuration of the terminal allows for more efficient use of space within tight environments. The rearward and forward stop surfaces ensure that the terminal remains fixed during both connection and disconnection, reducing wear and the risk of failure. Thus, the terms rearward and forward in this context describe a direction in relation with the mating direction. Forward means "in mating direction" and rearward means "against the mating direction" (i.e., in unmating direction).

[0008] This can be improved when the terminal is engaged with a first latching means of the connector housing, such that the movement of the terminal relative to the housing is blocked in a direction perpendicular to the mating direction.

[0009] Such a feature could be particularly useful in environments where the connector might be subjected to external forces or vibrations. The first latching mechanism provides an extra layer of stability, preventing the terminal from loosening or shifting out of alignment. This improved alignment enhances the electrical connection's reliability and longevity, reducing the risk of connection failure due to misalignment or wear.

[0010] Further improvement is achieved when the connector housing comprises a mating section, adapted to circumferentially receive the connection section of the terminal, preferably forming a round shaped hollow cylinder.

[0011] Such a mating section could be utilized in applications where a secure and precise fit is important, such as in high-frequency data or signal transmission. The circumferential engagement of the terminal improves the connection's stability by evenly distributing mechanical forces around the terminal, preventing it from shifting or loosening.

[0012] This embodiment can be further improved when the mating section forms a first round shaped hollow cylindrical segment, wherein the arc angle Θ of the segment is between 180 and 270 degree, preferably between 210 and 240 degree and most preferably 225 degree.

[0013] Such a cylindrical segment could be used in applications where space constraints or the need for easier assembly and disassembly are critical. The partial cylindrical segment allows the terminal to be securely held in place while also enabling easier insertion and removal of the retainer. The specific arc angle ensures that there is enough enclosure to provide a strong mechanical hold on the terminal while leaving an open section that facilitates access for installation of the retainer and / or the terminal itself.

[0014] This can be further improved when the retainer comprises a second round shaped hollow cylindrical segment, adapted to form a closed hollow cylinder with the first second round shaped hollow cylindrical segment in mounted condition.

[0015] Such a retainer could be beneficial in environments where a completely enclosed terminal is necessary for protection against external factors, such as dust, moisture, or mechanical impact. By forming a closed cylinder around the terminal, the connector ensures that the terminal remains firmly in place while providing additional shielding from environmental influence.

[0016] Further improvement can be achieved when the retainer comprises a cavity, adapted to hold a terminal and wherein the retainer further comprises a fastener, configured to releasably retain the terminal in the retainer.

[0017] Such a retainer could be useful in applications requiring maintenance or replacement of terminals. The releasable fastener ensures that the terminal is held securely during operation but allows for easy disconnection when needed, thus simplifying repair or upgrades.

[0018] This can be further improved when the fastener is attached to the retainer by means of a film hinge.

[0019] Such a film hinge could be beneficial in applications requiring frequent adjustments or reconnections. The flexible hinge allows for easy manipulation of the fastener without the risk of losing separate components, thus simplifying assembly and maintenance processes. The film hinge also reduces the likelihood of mechanical failure by minimizing the number of discrete parts.

[0020] This can be further improved when the fastener is adapted to retain at least one terminal inside the retainer by closing the fastener and to retain another terminal, that is arranged in the connector housing, when the retainer is mounted to the connector housing.

[0021] Such a fastener could be advantageous in complex systems where multiple terminals need to be connected and secured at once. The ability of the fastener to retain multiple terminals ensures a strong and reliable connection. Such a connector also simplifies assembly and reduces the number of individual components, enhancing both the efficiency and reliability of the connector.

[0022] This can be further improved when the retainer comprises a retainer connection section, adapted to receive the connection section of the terminal and a retainer attachment section, adapted to receive the attachment section of the terminal, and wherein retainer connection section and the retainer attachment section are arranged at 90° with respect to each other.

[0023] Such a configuration would be particularly useful in space-constrained environments where compact and efficient routing of conductors is essential. The 90-degree arrangement allows for optimized use of space, thus ensuring that the connection and attachment sections are securely held while maintaining the necessary right-angle configuration. This design also enhances the stability and performance of the connector by providing dedicated sections for both the electrical connection and mechanical attachment points, thus ensuring reliable and robust operation.

[0024] This can be further improved when the retainer is adapted to retain at least one terminal and the housing is adapted to hold at least one other terminal and the fastener is arranged between the terminal inside the retainer and the terminal in the housing in mounted condition of housing and retainer.

[0025] Such a design can be effective in multi-terminal connectors. By positioning the fastener between the terminals in both the retainer and housing, the design ensures that all terminals are properly aligned and securely fastened in one step. This simplifies the assembly process, reduces the risk of terminal displacement during use, and ensures consistent electrical contact, even in demanding environments subject to vibration or movement or the like.

[0026] Further improvement can be achieved when the retainer is attachable to the housing by moving the retainer against the mating direction.

[0027] Such a retainer is useful in scenarios where space constraints or ease of assembly are important. By allowing the retainer to be attached from the direction opposite to the mating direction of the connector, the design simplifies installation and provides better access to the terminals during assembly or maintenance.

[0028] Further improvement can be achieved when the housing has a right-angled configuration with a mating section, adapted to be circumferentially around the connection section of the terminal in mounted condition, and a main section adapted to receive the attachment section of the terminal in mounted condition.

[0029] Such a right-angled configuration can be useful in applications where space management is important, such as in densely packed automotive systems. The design allows for efficient routing of wires and terminals at a go-degree angle, optimizing space and improving the layout of the wiring. By securely holding both the electrical and mechanical parts of the terminal, the connector ensures a stable and reliable performance under various operating conditions.

[0030] Another aspect of the invention relates to a method of assembling a right-angled connector, comprising: inserting a right-angled terminal configured to be attached to a conductor into a terminal cavity of a connector housing along a first insertion direction, the connector housing comprising a rearward stop surface bordering the terminal cavity; attaching a retainer configured to enclose the terminal cavity to the connector housing along a second insertion direction, the cover defining a forward stop surface configured to retain the right-angled terminal within the terminal cavity; and disposing a portion of the right-angled terminal between the rearward stop surface and the forward stop surface.

[0031] Such a method offers an efficient way to assemble right-angled connectors in environments where space is limited, such as in automotive or electronic systems. By utilizing distinct rearward and forward stop surfaces, the method ensures that the terminal is properly aligned and securely fastened within the connector housing, preventing unwanted movement during operation.

[0032] This method can be further improved when the right-angled terminal comprises a connection section configured to interface with a corresponding terminal along a connection axis and an attachment section configured to be attached to a conductor and wherein the connection axis is substantially perpendicular to the first insertion direction, wherein preferably the connection axis is substantially parallel to the second insertion direction.

[0033] Such a method is suitable for use in applications requiring precise terminal alignment. The perpendicular relationship between the connection axis and the first insertion direction ensures a compact, efficient design, while the parallel alignment with the second insertion direction simplifies assembly and enhances terminal stability. This method leads to improved electrical contact and greater mechanical integrity in space-restricted environments.

[0034] This method can be further improved when the attaching of the retainer is achieved by a first step of moving the retainer in a direction parallel to the first insertion direction and a second step of moving the retainer in a direction parallel to the second insertion direction.

[0035] Such a method provides a controlled and precise way to assemble the connector, ensuring that the retainer securely locks into place without misalignment. This method is beneficial in situations where the connector needs to withstand vibrations or mechanical stress. The two sequential steps help ensure a robust mechanical and electrical connection, thus reducing the likelihood of assembly errors.4. Brief description of the figures

[0037] The subsequent sections provide a detailed description of the invention, referencing the accompanying illustrations for clarity. The descriptions represent examples only and are not intended to limit the invention's scope. Identical reference numerals across the figures and text denote the same components. The illustrations may not reflect actual size or scale; their dimensions, proportions, and depictions of elements might be enhanced for better understanding and visual convenience.

[0038] Figure 1 illustrates a right-angled connector 1 according to the invention in a perspective view. A right-angled terminal 200 is mounted inside the connector housing 100. A retainer 300 retains the terminal 200 inside the connector housing 100 and is attached to the connector housing by the engagement of a second latching means 102 of the housing with a counter latching means 320 of the retainer. The mating section 130 circumferentially encloses, respectively receives a connection section 210 of the terminal 200 (cf. also to Fig. 4A), forming a round shaped hollow cylinder. The housing 100 has a right-angled configuration with a mating section 130, that is circumferentially around the connection section 210 of the terminal 200, and a main section 140 that encloses the attachment section 220 of the terminal 200.

[0039] Such a design ensures that the terminal is firmly retained in position while allowing for reliable electrical contact due to the round, circumferential enclosure of the connection section. This configuration is useful for maintaining a stable connection in applications subjected to physical movement or vibrations, ensuring the terminal remains properly aligned within the connector housing for consistent performance.

[0040] Figure 2 shows the retainer 300 of Figure 1 in a perspective view. The retainer 300 comprises counter latching means 320 to engage the second latching means 102 of the housing for attaching the retainer to the connector housing 100. The retainer 300 further comprises a forward stop surface 310, configured to block a movement of the terminal relative to the housing in mating direction when the retainer 300 is mounted on the housing.

[0041] Such an engagement of the counter-latching means and the forward stop surface provides a robust mechanism for securing the terminal within the connector. This dual functionality not only keeps the terminal properly aligned but also ensures that it cannot be pushed too far forward during the mating process, which is particularly important in ensuring consistent electrical performance and mechanical durability in high-vibration or dynamic environments.

[0042] Figure 3 shows the housing 100 of Figure 1 in a cross-sectional view. The housing 100 comprises the mating section 130, that is adapted for mating with a corresponding counter connector. Inside the housing, a terminal cavity 120 is provided to receive the terminal 200 therein. The housing further comprises first latching means 101, adapted to engaged with the terminal, such that a movement of the terminal relative to the housing is blocked in a direction perpendicular to the mating direction. A rearward stop surface 110 is configured to maintain the terminal withing the terminal cavity 120 against a movement in unmating direction. The terminal cavity 120 holds the terminal in mounted condition. The second latching means 102 are adapted to engage with the counter latching means of the retainer.

[0043] Such a design securely fastens the retainer to the housing, effectively locking the terminal in place between the rearward stop surface and the forward stop surface provided by the retainer, ensuring stable and reliable operation. The design allows for precise alignment and retention of the terminal within the connector, which is important for maintaining strong electrical contact and resisting external forces. The use of multiple latching mechanisms enhances both the mechanical strength and durability of the connector.

[0044] Figures 4A-4C illustrate the assembling of the connector 1 in a perspective view. In Figure 4A the right-angled terminal 200 comprises a connection section 210 configured to interface with a corresponding terminal along a connection axis and an attachment section 220 configured to be attached to a conductor 221. The mating section 130 on the housing 100 forms a first round shaped hollow cylindrical segment, wherein the arc angle Θ of the segment is about 270 degree. The Terminal 200 can be mounted in the housing by moving it in the direction of the arrow. Figure 4B depicts the terminal 200 mounted in the terminal cavity 120 of the connector housing 100. The first latching means 101 of the housing engage with the connection section 210 of the terminal and block movement of the terminal against the mounting direction of the terminal 200.

[0045] Figure 4C shows the mounting of the retainer 300 onto the housing 100 by moving the retainer against the mating direction of the connector 1 as indicated by the arrow. The retainer 300 comprises a second round shaped hollow cylindrical segment 330, adapted to form a closed hollow cylinder with the first round shaped hollow cylindrical segment 130 in mounted condition.

[0046] Such an assembly process ensures that the right-angled terminal is properly secured within the connector housing, maintaining alignment and preventing movement during operation. The 270-degree cylindrical mating section offers mechanical support to the connection section, while the latching mechanisms provide additional security, ensuring that the terminal remains securely fixed.

[0047] Figure 5 depicts another connector 5 according to the invention in a perspective view. A right-angled terminal 600 is mounted inside the connector housing 500. A retainer 700 retains the terminal 600 inside the connector housing 500 and is attached to the connector housing by the engagement of second latching means 502 of the housing with counter latching means 720 of the retainer. The mating section 530 circumferentially encloses the connection section 610 of the terminal 600, forming a round shaped hollow cylinder. One part of the mating section 530 is open, respectively forms not a full cylinder but only a cylindrical segment. The retainer 700 correspondingly comprises a second round shaped hollow cylindrical segment 730, adapted to form a closed hollow cylinder with the open part of the mating section 530. Thereby, the fully closed round shaped hollow cylindrical segment 530 is formed in mounted condition.

[0048] Such a design offers reliable mechanical and electrical stability, ensuring that the terminal is both physically protected and electrically connected. The cylindrical mating section provides robust mechanical support, reducing the risk of terminal movement or misalignment during operation.

[0049] Figure 6 shows the retainer 700 of the connector of Figure 5 in a perspective view. The retainer 700 comprises counter latching means 720 to engage the second latching means 502 of the housing. The retainer 700 further comprises a forward stop surface 710, configured to stop movement of the terminal 600 in mating direction.

[0050] Such a configuration with forward stop surface and the counter-latching mechanism working together provides a reliable retention system for the terminal. This design prevents any unwanted displacement of the terminal during connection.

[0051] Figures 7A-7C illustrate a mounting procedure of the terminal in the housing of the connector of Figure 5. The terminal 600 is inserted into the connector housing 500 in a superimposition of a rotational and translation movement until the terminal 600 engages the first latching means 501.

[0052] Such a mounting process with a combination of rotational and translational movement facilitates smoother insertion, reducing the risk of misalignment or damage to the terminal or housing.

[0053] Figures 8A-8C depict another mounting procedure of the terminal in the housing of the connector of Figure 5. The terminal 600 is inserted into the connector housing 500 in a rotational movement until the terminal 600 engages the first latching means 501.

[0054] Such a rotational mounting procedure simplifies the insertion process, allowing for precise alignment of the terminal within the housing with minimal effort. The rotational movement facilitates smoother engagement with the latching mechanism, ensuring that the terminal is properly.

[0055] Figures 9A-9C show the two-step assembly of the retainer in the housing of the connector 5 of Figure 5. In Figure 9A the retainer 700 is moved upwards in the figure, i.e. perpendicular to the mating direction in a first retainer assembly step. Figure 9B depicts a second retainer assembly step of moving the retainer 700 in the unmating direction of the connector. Figure 9C shows the mounted retainer 700 in the housing 500 with the engagement of the second latching means 502 with the counter latching means 720. The retainer 700 forms a closed hollow cylinder with the open part of the mating section 530.

[0056] Such a two-step assembly method provides a precise and controlled attachment process for the retainer, ensuring both proper alignment and secure retention. The dual-direction movements allow for smoother assembly and reduce the risk of misalignment or damage.

[0057] Figure 10 depicts another connector 10 according to the invention in a perspective view. Also in this embodiment, a retainer 1200 encloses multiple terminals 1100 and is mounted in the housing 1000.

[0058] Figure 11A-11C depicts the mounting procedure of the terminals with the retainer 1200 of the connector of Figure 10. Figure 11A shows the retainer 1200 and the terminals 1100. The retainer 1200 comprises two cavities 1201, adapted to receive the terminals 1100. The retainer 1200 further comprises a fastener 1250, configured to releasably retain the terminals 1100 in the retainer 1200. Figure 11B shows the terminals 1100 arranged inside the cavities 1201 of the retainer 1200 and the fastener 1250, which is attached to the retainer 1200 by means of a film hinge 1251. Figure 11C shows the closed fastener 1250, such that the terminals 1100 are retained in the retainer 1200. The retainer 1200 comprises a retainer connection section 1210, adapted to receive the connection section 1110 of the terminal 1100 and a retainer attachment section 1220, adapted to receive the attachment section of the terminal 1120, and wherein retainer connection section 1210 and the retainer attachment section 1220 are arranged at 90° with respect to each other.

[0059] Such a mounting procedure allows for secure and efficient retention of multiple terminals within the retainer. The use of the film hinge simplifies the closing mechanism by keeping the fastener attached to the retainer, reducing the risk of losing parts during assembly. This design is beneficial in applications where multiple terminals need to be retained securely, ensuring reliable connections and easy assembly or maintenance. The fastener's releasable feature also allows for convenient removal or replacement of terminals when necessary.

[0060] Figure 12 shows the mounting procedure of two terminals 1100 in the housing 1000 of the connector of Figure 10. The terminals 1100 are moved in the terminal mounting direction, until the terminals are mounted in the housing 1000 by engaging with the first latching means 1001.

[0061] Figure 13A-13B depict the mounting procedure of the retainer in the housing of the connector of Figure 10 and 12. In Figure 13A, the housing 1000 holds the two mounted terminals 1100, while the retainer 1200 holds two additional terminals 1100'. Figure 13B shows the mounted retainer 1200 on the housing 1000, thus forming a connector 10 with four terminals. The retainer 1200 is attachable to the housing by moving the retainer against the mating direction of the connector. The fastener 1250 retains the two terminals 1100' inside the retainer 1200 and it also retains the two other terminals 1100, that are pre-mounted in the connector housing, when the retainer (1200) is mounted to the connector housing as shown in Fig. 13B. As one can take from the figure, the retainer 1200 is adapted to retain two terminals and the housing is adapted to hold two other / additional terminals. In mounted condition of housing and retainer, the fastener 1250 is arranged between the terminals inside the retainer and the terminals in the housing. The retainer 1200 is attachable to the housing by moving the retainer 1200 against the mating direction, as mounting guides 1300 attached on two sides of the retainer allow movement only against mating direction.

[0062] Such a design allows for the combination of terminals from both the housing and the retainer, providing a compact and efficient solution for multi-terminal connections. The secure retention of the terminals through both the housing and the retainer ensures reliable electrical contact and mechanical stability. The design also facilitates modular assembly, enabling easy maintenance or replacement of individual components without compromising the entire connector's integrity.References:
