[0005]

[0001] The present application relates to a connector that can be applied to a vehicle as a connector for connecting an in-vehicle cable.

Background Art

[0002] With the development of communication technologies, the requirements for data transmission are becoming increasingly high. In order to improve the data transmission speed and reduce the cable cost of data transmission, terahertz waves are increasingly used as information carriers for communication. Terahertz waves are electromagnetic waves with a wavelength band between millimeter waves and visible light, and optical fibers are used as communication media. Compared with conventional microwave communication using cables as media, terahertz communication can easily achieve signal transmission exceeding 10 Gbps and has advantages such as broad spectrum resources, low quantum energy, and wide bandwidth.

[0003] Current terahertz connector assemblies for connecting optical fibers cannot guarantee stable signal connections in a vibration environment. Water and dust can penetrate into the connectors, and the optical fibers are easily contaminated. The connectors are large-sized or have many requirements for processing technology, resulting in high costs.

[0004] Therefore, there is a need for a connector that can adapt to a vibration environment in order to improve the stability of signal connections and prevent water and dust from contaminating the optical fibers.

Summary of the Invention

Means for Solving the Problems

[0005] In consideration of the above problems, the present application provides a connector. The connector can improve the reliability of line connections and maintain signal stability.

[0006] A first aspect of this application provides a connector comprising a first housing and a metal coupling member, the metal coupling member being mounted on the first housing and having a first surface and a second surface opposite to each other, the first surface having a first hole and the second surface having a second hole.

[0007] According to the connector structure described above, two cables can be inserted separately into the first and second holes, thereby achieving connection between the two cables by the coupling of a metal coupling member. Compared to conventional methods of crimping a gold finger and a spring piece, for example, such a connection method can improve the reliability of the connection and maintain signal stability. Specifically, for example, when the connector is applied to an automotive scenario, if conventional methods of crimping a gold finger and a spring piece are used, the spring piece will elastically deform when the vehicle vibrates, which can cause the spring piece to temporarily separate from the gold finger and potentially lead to signal instability. However, according to the connector of the first aspect of this application, the cables are inserted into the first and second holes to achieve connection. Therefore, the cables can be held relatively stably within the holes, improving connection reliability and signal stability.

[0008] Furthermore, the cable is inserted into the hole, and the signal is transmitted via a metal coupling member in contact with the inner wall of the hole. This reduces transmission loss and improves signal stability.

[0009] Furthermore, the two cables are connected via a metal coupling, eliminating the need for direct contact, which contributes to waterproofing and dustproofing.

[0010] In possible embodiments, the first hole and / or the second hole include multiple tapered bore sections or one tapered bore section.

[0011] According to the above-described arrangement, the contact area between the cable and the metal coupling member can be increased, transmission loss can be reduced, and coupling efficiency can be improved. In some embodiments, transmission with a loss of less than 2.5 dB / end can be achieved.

[0012] In possible embodiments, the first hole and / or the second hole are multiple blind holes or one blind hole.

[0013] In other words, the first hole is not connected to the second hole, which prevents water and dust from entering the second hole from the first hole, and prevents water and dust from entering the first hole from the second hole, thereby improving the waterproof and dustproof effect.

[0014] In possible embodiments, a first metallic shielding layer is placed between the metallic coupling member and the first housing.

[0015] According to the above arrangement, electromagnetic compatibility (EMC) performance can be improved, interference between the cable connected to the metal coupling member and other equipment is reduced, and the degree of interference prevention of the cable to other equipment is improved.

[0016] In possible embodiments, the hoop is positioned around the opening of the first hole.

[0017] According to the arrangement described above, the metal coupling member can be fixed inside the first housing, the installation method is simple, and the installation structure is reliable.

[0018] In possible embodiments, a collar is further included, which is positioned in a second hole.

[0019] According to the above arrangement, the cable is 2The collar is firmly fixed in the hole, ensuring a secure fit between the cable and the metal connector. This further prevents poor contact between the cable and the metal connector caused by vibration, improving signal transmission quality. The collar is tightly attached to the end of the cable, preventing water, dust, etc. from entering the second hole and contaminating the contact surface between the cable and the second hole, thereby avoiding oxidation and corrosion of part of the metal connector within the second hole.

[0020] In possible embodiments, the first housing is made of a plastic material.

[0021] According to the above arrangement, assembly and fixing of the metal coupling member and the first housing become easy, the assembly method is simple, material costs are low, and large-scale manufacturing and assembly are easy.

[0022] In possible embodiments, the metal connector is made of copper.

[0023] According to the above arrangement, the signal transmission efficiency can be improved.

[0024] A second aspect of this application provides a connector comprising a second housing and a wire fixing portion, the wire fixing portion being installed within the second housing and comprising a tubular portion having a through hole and a protruding edge, the protruding edge being located on one side of the tubular portion, the through hole communicating with a first hole of a metal coupling member installed within the first housing to seal a wire within the first hole, the metal coupling member comprising a first surface and a second surface opposite to each other, the first hole being provided on the first surface and the second hole being provided on the second surface.

[0025] The wire fixing part is configured to be connected to a cable. According to the connector with the above-described structure, the wire inserted into the first hole may be installed in the second housing by using the wire fixing part. Then, the wire inserted into the first hole is coupled to the wire inserted into the second hole by using a metal coupling member, thereby realizing the connection between two cables (i.e., wires). For example, compared with the conventional method of crimping a gold finger and a spring piece, such a connection method can improve the reliability of the connection and maintain the stability of the signal. Specifically, for example, when the connector is applied to an in-vehicle scenario, if the conventional method of crimping a gold finger and a spring piece is used, the spring piece elastically deform when the vehicle vibrates, thereby causing the spring piece to be temporarily separated from the gold finger, and the signal may become unstable. However, according to the connector of the second aspect of the present application, the cable is inserted into the first hole and the second hole to realize the connection. Therefore, the cable can be relatively stably held in the hole, and the reliability of the connection and the stability of the signal are improved.

[0026] Also, the cable is inserted into the hole, and the signal is transmitted through the inner wall of the hole and via the metal coupling member in contact therewith, whereby the transmission loss can be reduced and the stability of the signal can be improved.

[0027] Furthermore, the two cables perform signal connection by the coupling of the metal coupling member and do not need to be in direct contact, which is useful for waterproofing and dustproofing.

[0028] In a possible embodiment, the wire fixing part is configured as a stepped flange plate.

[0029] The portion with a small diameter of the stepped flange plate structure can be attached to the inner wall of the second housing, and the portion with a large diameter of the stepped flange plate structure can be adapted to the inner wall of the second housing, whereby one end of the cable can be sealed in the first hole. Therefore, oxidation and corrosion of the portion of the metal coupling member within the first hole are avoided. The stepped flange plate structure is simple and facilitates assembly and processing.

[0030] In a possible embodiment, a metal pin is further included, the metal pin being fixed to the second housing and extending outwardly with respect to the second housing.

[0031] In a possible embodiment, a second metal shielding layer is disposed on the hole wall of the through hole.

[0032] According to the above-described arrangement, the performance of electromagnetic compatibility (EMC) can be improved, the interference of the cable coupled to the metal coupling member to other devices is reduced, and the interference prevention degree of the cable to other devices is improved.

[0033] The third aspect of the present application provides a signal line. The signal line includes a line body and a connector provided in any one of the possible embodiments of the first aspect and the first aspect of the present application, or includes a line body and a connector provided in any one of the possible embodiments of the second aspect and the second aspect of the present application, and an end of the line body is inserted into the first hole or the second hole.

[0034] In a possible embodiment, the end of the line body includes a tapered portion.

[0035] According to the above-described arrangement, the contact area between the cable and the metal coupling member can be increased, and the transmission loss can be reduced. In some embodiments, transmission with a loss less than 2.5 dB / end can be achieved.

[0036] In a possible embodiment, the line body includes a plastic optical fiber.

[0037] The structure of plastic optical fibers can prevent dust from entering the plastic optical fibers and affecting the signal transmission quality.

[0038] A fourth aspect of this application provides a connector, which includes a connector provided in any one of the first aspect and a possible embodiment of the first aspect of this application, and a connector provided in any one of the second aspect and a possible embodiment of the second aspect of this application.

[0039] According to the collar and stepped flange plate positioned in the second hole of the metal coupling member provided in this application, the ends of the plastic fiber can be sealed separately in the first and second holes to prevent dust and water from entering the plastic fiber and contaminating the contact surface between the plastic fiber and the metal coupling member. Plastic fibers configured as solid fibers can also be prevented from dust entering the plastic fiber and affecting signal transmission quality. The first and / or second holes having tapered portions can increase the contact area between the plastic fiber and the metal coupling member, thereby reducing transmission loss. The first and second housings of this application are made of plastic, are reliable in installation, easy to manufacture, low-cost, and easy to manufacture and assemble on a large scale.

[Figure 8] This is an exploded view of yet another connector with plastic fibers installed according to one embodiment of the present application. [Figure 9] This is a schematic diagram of a structure in which the connector shown in Figure 1 and another connector shown in Figure 5 are installed together. [Figure 10] This is a cross-sectional view of Figure 9. [Modes for carrying out the invention]

[0042] The connectors provided in the embodiments of this application may be applied, for example, to connections between wires in a vehicle, or to connections between terahertz plastic fibers used to transmit terahertz waves.

[0043] Figure 1 is a schematic diagram of the structure of a connector 100 into which a plastic fiber 3 is installed according to one embodiment of the present application. The connector 100 provided in one embodiment of the present application (also called a board-end connector or female connector) may be configured to connect to a circuit board of a controller. As shown in Figure 1, the connector provided in this embodiment of the present application includes a first housing 1 and a metal coupling member 2. The metal coupling member 2 may be configured to connect to a plastic fiber 3. Figure 2 is a cross-sectional view of the connector 100 shown in Figure 1. As shown in Figure 2, the metal coupling member 2 is installed in the first housing 1. The metal coupling member 2 includes a first face 21 and a second face 22 that are opposite to each other. A first hole 211, configured to be inserted by a first plastic fiber 6 (see Figure 10), is located on the first face 21. A second hole 221, configured to be inserted by a second plastic fiber 3, is located on the second face 22.

[0044] Two cables (for example, a first plastic fiber 6 and a second plastic fiber 3) are inserted separately into the first hole 211 and the second hole 221 of the metal coupling member 2, thereby enabling signal connection between the cables by coupling the metal coupling member 2.

[0045] For example, compared to the conventional method of crimping a gold finger and a spring piece, such a connection method can improve the reliability of the connection and maintain signal stability. Specifically, for example, when the connector is applied to an automotive scenario, if the conventional method of crimping a gold finger and a spring piece is used, the spring piece will elastically deform when the vehicle vibrates, which can cause the spring piece to temporarily separate from the gold finger and potentially lead to signal instability. However, according to the connector 100 of the first aspect of this application, the cable is inserted into the first hole 211 and the second hole 221 to achieve the connection. Thus, the cable can be held relatively stably within the hole, improving the reliability of the connection and signal stability.

[0046] Furthermore, the cable is inserted into the hole, and the signal is transmitted via a metal coupling member in contact with the inner wall of the hole. This reduces transmission loss and improves signal stability.

[0047] Furthermore, the two cables are connected by a metal coupling member 2, eliminating the need for direct contact, which helps with waterproofing and dustproofing.

[0048] In the embodiment shown in Figure 1, the metal coupling member 2 is housed within the first housing 1, thereby securing the metal coupling member 2 to the first housing 1, and thus securing the cable to the connector 100. When the connector 100 is applied to connections between wires transmitting terahertz waves within a vehicle, poor contact between the wires and the metal coupling member 2 due to vehicle vibration can be prevented, improving signal transmission quality.

[0049] In some embodiments, as shown in Figure 1, the first hole 211 and / or the second hole 221 are either multiple blind holes or a single blind hole. Specifically, the first hole 211 and the second hole 221 are not in communication with each other. This prevents water and dust from entering the second hole 221 from the first hole 211, or vice versa, thereby improving the waterproof and dustproof effect.

[0050] In some embodiments, the metal coupling member 2 may be an elongated column, as shown in Figures 2 and 10. The first hole 211 and the second hole 221 are provided separately on the end faces of both ends of the column, and the first hole 211 and / or the second hole 221 include multiple tapered holes 212 or one tapered hole. Correspondingly, the end of the first plastic fiber 6 inserted into the first hole 211 and the end of the second plastic fiber 3 inserted into the second hole 221 are pre-cut to a tapered shape. The outer circumferential surface of the tapered end of the plastic fiber is attached to the inner circumferential surface of the tapered portion of the first hole 211 and the second hole 221, respectively, thereby effectively increasing the contact area between the plastic fiber and the metal coupling member, enabling low-loss transmission, for example, transmission where end-to-end transmission loss of less than 2.5 dB is achieved at each end.

[0051] In some embodiments, the metal connector 2 may alternatively have a different shape, such as a substantially rectangular parallelepiped or a triangular prism. The first hole 211 and / or the second hole 221 may alternatively have a cylindrical or prismatic shape. Correspondingly, the ends of the first plastic fiber 6 inserted into the first hole 211 and the ends of the second plastic fiber 3 inserted into the second hole 221 are pre-cut into a cylindrical or prismatic shape. The outer circumferential surfaces of the ends of the cylindrical or prismatic plastic fibers are attached to the inner circumferential surfaces of the cylindrical or prismatic portions of the first hole 211 and the second hole 221, respectively.

[0052] Optionally, the plastic fiber may be a solid fiber made of a material with a low dielectric constant, and the solid fiber structure can prevent dust from entering the solid fiber and affecting the signal transmission quality of the plastic fiber. Optionally, the metal connector 2 may be made of copper. It will be understood that the metal connector 2 may be made of another metal instead.

[0053] In some embodiments, as shown in Figure 2, the connector further includes a collar 25. The collar 25 is positioned in the second hole 221 and is configured to seal the gap between the second plastic fiber 3 and the second hole 221. The collar 25 may be made of plastic. Before the second plastic fiber 3 is inserted into the second hole 221, the collar 25 may be sleeved at one end of the second plastic fiber 3, and then the second plastic fiber 3 is inserted into the second hole 221, thereby securing the collar 25 in the second hole 221. Furthermore, the second plastic fiber 3 is also secured to the metal coupling member 2 by using the collar 25. In one embodiment, this securing configuration ensures attachment and fixation between the plastic fiber and the metal coupling member 2, preventing poor contact caused by vibration from affecting the quality of the signal transmitted over the terahertz wave. In another embodiment, the collar 25 can prevent water from entering the second hole 221 and prevent external dust and dirt from contaminating the contact surface between the plastic fiber and the metal connector 2.

[0054] In some embodiments, as shown in Figure 2, a first metal shielding layer 23 may be further positioned between the metal coupling member 2 and the first housing 1 to shield against other electromagnetic signals. The first metal shielding layer 23 may be sleeved on the outer circumference of the metal coupling member 2, thereby improving the electromagnetic compatibility performance of the connector, reducing interference to other equipment caused by the cable coupled to the metal coupling member 2, and also improving the degree of interference prevention of the cable coupled to the metal coupling member 2. Optionally, the first metal shielding layer 23 is made of copper. Furthermore, the first metal shielding layer 23 may be grounded.

[0055] In some embodiments, as shown in Figure 3, the hoop 24 may be positioned around the opening of the first hole 211 and configured to fix the metal coupling member 2 to the first housing 1. The hoop 24 may be an annular component having a step on its outer circumference, the inner circumference of the hoop 24 being connected to the first hole 211, and the stepped portion of the hoop 24 being able to abut against the inner wall of the first housing 1.

[0056] In some embodiments, as shown in Figures 3 and 4, the first housing 1 may include a housing body 101 and a fastener 102 configured to secure a metal coupling member 2 within the housing body 101. The housing body 101 has a first chamber 11, which has a first opening 111 and a second opening 13 opposite to each other in the opening direction. The first opening 111 is used to receive a second housing 4 (see Figure 5) of a male connector 200, thereby coupling a first plastic fiber 6 (see Figure 10) fixed within the male connector 200 into a first hole 211 of the metal coupling member 2. The second opening 13 is used to secure the metal coupling member 2. A support portion 16 supporting the metal coupling member 2 may be located in the second opening 13, and the support portion 16 extends outward from the first housing relative to the second opening 13.

[0057] As shown in Figures 2 and 3, the fastener 102 can partially surround the metal coupling member 2, and the retaining ring 15 is positioned on both sides of the fastener 102. As shown in Figure 4, projections 14 that fit into the retaining ring 15 are positioned on both sides of the support portion 16 of the second opening 13, and the projections 14 have a slope. When assembling the housing body 101, the metal coupling member 2, and the fastener 102, the metal coupling member 2 is first inserted into the second opening 13, and the stepped portion of the metal coupling member 2 abuts against the inner wall of the housing body 101. Then, pressure is applied to the fastener 102 in the direction of the arrow in Figure 4, thereby deforming the retaining ring 15 until it abuts against the slope of the projection 14 and the projection 14 is fully positioned within the retaining ring 15 under the action of the slope.

[0058] In some embodiments, the first housing 1 may be made of plastic material, and the housing body 101 and fasteners 102 may deform during installation and assembly to ensure installation reliability. Furthermore, the installation process is simple, the process is easy to carry out, the cost is low, and large-scale manufacturing and installation are easy.

[0059] As shown in Figures 1 to 4, metal fixing pins 12 are further positioned on the housing body 101. The metal fixing pins 12 are configured to fix the first housing 1 of the connector 100 to the circuit board. The metal fixing pins 12 extend outward relative to the housing body 101. Electrical contact pins 17 are further positioned on the housing body 101 and are configured to be electrically connected to the male connector 200 (see Figure 10).

[0060] Figure 5 is a cross-sectional view of another connector according to one embodiment of the present application. As shown in Figure 5, the connector 200 (also called a male connector or wire end connector) includes a second housing 4 and a wire fixing portion 5 for fixing a first plastic fiber 6. The wire fixing portion 5 is installed on the second housing 4 and is configured in the shape of a flange plate. Specifically, the wire fixing portion 5 includes a tubular portion 53 with a through hole 51 and a protruding edge 52, the protruding edge 52 being positioned at one end of the tubular portion 53. After one end of the first plastic fiber 6 is inserted into the through hole 51, the wire fixing portion 5 is inserted into the second housing 4, and the wire fixing portion 5 is sandwiched between the first plastic fiber 6 and the second housing 4, thereby fixing the first plastic fiber 6 to the second housing 4. When connector 200 is configured for connecting cables used to transmit terahertz waves within a vehicle, poor contact between the cable and the metal coupling member 2 caused by vehicle vibration can be prevented, and the quality of the signal transmitted by the cable is improved.

[0061] As shown in Figure 6, the second housing 4 may include a second housing body 41, a fixing piece 42, and a subconnector 43. The subconnector 43 is configured to accommodate the wire fixing portion 5, as shown in Figures 5, 7, and 8, and the subconnector 43 can be inserted into the second housing body 41. The fixing piece 42 is configured to fix the subconnector 43 to the second housing body 41.

[0062] As shown in Figures 5 and 6, a subconnector hole 411 for installing the subconnector 43 is provided in the second housing body 41. A plug-in fastener 44 that fits the female connector 100 and a locking means 412 that fits the fixing piece 42 and protrudes from the second housing body 41 are located on the outside of the second housing body 41.

[0063] As shown in Figures 5 and 6, the outer circumference of the subconnector 43 may be stepped, and the subconnector 43 can be partially inserted into the subconnector hole 411. Correspondingly, the subconnector hole 411 conforms to the outer circumference shape of the subconnector 43 and is also stepped. The wire fixing section through hole 431 is provided inside the subconnector 43 and includes a portion that conforms to the outer circumference shape of the wire fixing section 5, for example, a portion with a small diameter and a portion with a large diameter. The portion with a small diameter is attached to the outer circumference of the tubular portion 53 of the wire fixing section 5, and the portion with a large diameter abuts against the protruding edge 52, thereby fixing the wire fixing section 5 in the wire fixing section through hole 431.

[0064] As shown in Figure 6, the fixing piece 42 includes a surrounding portion 421, which can partially surround the subconnector 43 and the second housing body 41. The locking ring 422 is positioned on the edge of the surrounding portion 421 and can be sleeved on the locking means 412.

[0065] As shown in Figures 6 to 8, when the second housing body 41, fixing piece 42, and subconnector 43 are fixed together, the subconnector 43 is partially inserted into the subconnector hole 411 of the second housing body 41. The surrounding portion 421 of the fixing piece 42 surrounds the subconnector 43 and the second housing body 41. The locking ring 422 at the edge of the surrounding portion 421 is sleeved on the locking means 412, and the inner edge of the locking ring 422 abuts against the locking means 412.

[0066] In some embodiments, the second housing body 41 is provided with an electrical contact hole 413 used for installing a cable 7, and the cable 7 is fixed to the electrical contact hole 413 by using a locking piece inside the electrical contact hole 413.

[0067] In some embodiments, as shown in Figures 5 and 6, the first plastic fiber 6 includes an inner core 61 and a cladding medium 62. The end of the inner core 61 is sharply conical, and one sharp conical end of the first plastic fiber 6 is inserted into a through-hole 51 of the wire fixing portion 5 from one end of a protruding edge 52 of the wire fixing portion 5 and attached to the hole wall of the first hole 211 of the metal connector 2. The first plastic fiber 6 and the through-hole 51 are closely fitted, so that the first plastic fiber 6 can be fixed to the second housing 4 and the quality of the signal transmitted by terahertz waves is prevented from being affected by poor contact caused by vibration. The structure of the protruding edge 52 of the wire fixing portion 5 can seal the inner core 61 of the first plastic fiber 6 into the first hole 211, preventing water from entering the first hole 211 and preventing external dust and dirt from contaminating the contact surface between the first plastic fiber and the metal connector 2.

[0068] In some embodiments, as shown in Figure 5, the second metal shielding layer 511 may be positioned on the wall of the through hole 51. The electromagnetic compatibility performance of the connector is improved, interference to other equipment caused by the first plastic fiber 6 coupled to the metal coupling member 2 is reduced, and the degree of interference prevention of the first plastic fiber 6 coupled to the metal coupling member 2 to other equipment is also improved. Optionally, the second metal shielding layer 511 is made of copper. Furthermore, the second metal shielding layer 511 may be grounded.

[0069] Figures 9 and 10 show schematic and cross-sectional views, respectively, of the male connector 200 and female connector 100 combined as a single unit. As shown in Figures 9 and 10, the second plastic fiber 3 is fixed to the second hole 221 of the metal coupling member 2 in the first housing 1 by using the collar 25. The first plastic fiber 6 is fixed to the second housing 4 by using the wire fixing part 5. The second housing 4 is inserted into the first chamber 11 of the first housing 1 by using the first opening 111. One end of the metal coupling member 2, which has the first hole 211, can be inserted into the subconnector hole of the subconnector 43, thereby attaching the tapered end of the first plastic fiber 6 to the hole wall of the first hole 211 and achieving a connection between the first plastic fiber 6 and the second plastic fiber 3.
