Technology Field

[0001] The present invention relates to a connector assembly for a video transmission cable, and more specifically, to a connector assembly for a video transmission cable capable of ensuring the fastening robustness of the connectors even when vibration and shock occur in a vehicle. Background Technology

[0003] Generally, video transmission cables applied to vehicles are connected to video receivers through a connector assembly. The connector assembly requires clearance between the connector sleeve and the connector housing to facilitate easy connection without interference between the connector terminals when the connectors are connected.

[0004] FIG. 6 is a drawing showing the state of a conventional connector assembly for a video transmission cable before connection, and FIG. 7 is a drawing showing the state of the connector assembly after connection.

[0005] As illustrated in FIGS. 6 and 7, a conventional connector assembly for a video transmission cable is composed of a first connector (10) and a second connector (20). The first connector (10) is composed of a connector sleeve (11) and a first connector terminal (12) provided within the connector sleeve (11), and the second connector (20) is composed of a connector housing (21) and a second connector terminal (22) provided within the connector housing (21). Additionally, the first connector (10) is provided with a connector cable (i.e., a video transmission cable) (13) connected to the first connector terminal (12).

[0006] In the above connector assembly, a gap exists between the connector sleeve (11) and the connector housing (21) to facilitate the connection of the connectors (10, 20). This gap causes poor contact between the second connector terminal (22) and the first connector terminal (12) during vehicle vibration, and causes video signal transmission errors due to said poor contact. Such video signal transmission errors lead to problems such as a black screen phenomenon where no image is displayed on the monitor inside the vehicle.

[0007] For example, if contact failure occurs between the connector terminals of a camera video transmission cable due to the impact of a vehicle accident, it can lead to a critical problem where video of the moment of the accident is not recorded. The problem to be solved

[0009] The present invention has been devised in consideration of the above-mentioned problems, and aims to provide a connector assembly for a video transmission cable configured such that the gap between the connectors is completely eliminated when the first connector and the second connector are connected, thereby maintaining the contact state of the connector terminals even under conditions of vibration or shock.

A portion of the non-conductive film layer is characterized in that, when the connector sleeve is inserted into the connector housing, it is separated from the outer surface of the connector sleeve by the film layer pusher and fills a front void in the space between the connector sleeve and the connector housing.

[0014] According to an embodiment of the present invention, the film layer pusher is characterized by being positioned at the axial center of the connector housing and extending in the circumferential direction of the connector housing.

[0015] In addition, the front gap is characterized as being a space between the opening of the connector housing and the film layer pusher.

[0016] In addition, the inner diameter of the film layer pusher is smaller than the outer diameter of the non-conductive film layer.

[0017] In addition, the connector sleeve is provided with a film layer stopper at its rear end; the film layer stopper is characterized by closing the front gap on the opposite side of the film layer pusher when a portion of the non-conductive film layer is separated from the outer surface of the connector sleeve by the film layer pusher.

[0018] In addition, the outer diameter of the film layer stopper is characterized by being larger than the inner diameter of the connector housing.

[0019] In addition, the first connector is characterized by including a connector cable that transmits a video signal to the first connector terminal. Effects of the invention

The details depicted in the attached drawings are schematic drawings intended to facilitate the explanation of the embodiments of the present invention and may differ from the actual implemented form.

[0028] Figure 1 attached is a drawing showing the state before fastening of a connector assembly for an image transmission cable according to an embodiment of the present invention, Figure 2 is a drawing viewed from AA of Figure 1, Figure 3 is a drawing viewed from BB of Figure 1, Figure 4 is a drawing showing the state after fastening of the connector assembly, and Figure 5 is a drawing viewed from CC of Figure 4.

[0029] As illustrated in FIG. 1, the connector assembly of the present invention comprises a first connector (100) and a second connector (200).

[0030] As illustrated in FIGS. 1 and 2, the first connector (100) is configured to include a connector sleeve (110), a first connector terminal (120), a non-conductive film layer (130), a film layer stopper (140), and a connector cable (150).

[0031] The connector sleeve (110) may be formed in a cylindrical shape with one end open and the other end closed. The connector sleeve (110) has one end open along the longitudinal direction of the first connector terminal (120). The connector sleeve (110) has a first opening (111) at one end for inserting the second connector terminal (220). For connecting the first connector (100) and the second connector (200), the connector sleeve (110) is inserted into the connector housing (210) of the second connector (200).

[0032] The first connector terminal (120) is positioned inside the connector sleeve (110). The first connector terminal (120) is positioned inside the connector sleeve (110) with one end fixed to the connector sleeve (110). The first connector terminal (120) extends long in the axial direction of the connector sleeve (110). The first connector terminal (120) may be positioned in the center of the connector sleeve (110) with respect to the radial direction of the connector sleeve (110).

[0033] A non-conductive film layer (130) is formed by coating a thin film on the outer surface of the connector sleeve (110). The non-conductive film layer (130) is coated entirely on the cylindrical outer surface of the connector sleeve (110). The non-conductive film layer (130) is formed from a non-conductive material, such as a material that does not conduct electricity, for example, a polymer.

[0034] As shown in FIGS. 4 and 5, when the connector sleeve (110) is inserted into the connector housing (210) of the second connector (200), this non-conductive film layer (130) fills the front void (241) in the space between the connector sleeve (110) and the connector housing (210).

[0035] A film layer stopper (140) is provided at the rear end of the connector sleeve (110). The film layer stopper (140) is provided at the rear end of the connector sleeve (110) with respect to the insertion direction of the connector sleeve (110) relative to the connector housing (210). In other words, the film layer stopper (140) is provided opposite the first opening (111).

[0036] The film layer stopper (140) is formed to have an outer diameter larger than the outer diameter of the connector sleeve (110) so as to protrude radially outward from the connector sleeve (110). The outer diameter of the film layer stopper (140) has a value larger than the inner diameter of the connector housing (210).

[0037] This film layer stopper (140) closes one side (i.e., the opening) of the front gap (241) opposite the film layer pusher (230) when a portion (i.e., the peeled portion) of the non-conductive film layer (130) is separated from the connector sleeve (110) by the film layer pusher (230) of the second connector (200). By closing one side of the front gap (241), the film layer stopper (140) prevents the peeled portion (131) of the non-conductive film layer (130) separated from the outer surface of the connector sleeve (110) from leaking out of the front gap (241) and ensures that the front gap (241) is completely filled by the non-conductive film layer (130).

[0038] Here, the non-conductive film layer (130) may be divided into a peelable portion (131) and a non-peeling portion (132). The peelable portion (131) is a portion that separates from the outer surface of the connector sleeve (110) when the connector sleeve (110) is inserted into the connector housing (210). The non-peeling portion (132) is a portion that does not separate from the outer surface of the connector sleeve (110) when the connector sleeve (110) is inserted into the connector housing (210).

[0039] The above peeling portion (131) is separated from the outer surface of the connector sleeve (110) by the film layer pusher (230) during the process of inserting the connector sleeve (110) into the connector housing (210) and moves toward the non-peeling portion (132). The above non-peeling portion (132) maintains a state of being coated on the outer surface of the connector sleeve (110) even after the connector sleeve (110) is fully inserted into the connector housing (210).

[0040] The connector cable (150) is a video transmission cable for transmitting a video signal acquired through a camera, etc. to a device such as a video receiver. One end of the connector cable (150) is fixed and supported at the rear end of the connector sleeve (110). The connector cable (150) is positioned on the outside of the connector sleeve (110) and is connected to the first connector terminal (120) to enable the transmission of a video signal. The connector cable (150) can transmit a video signal to the first connector terminal (120). Although not shown in the drawing, the connector cable (150) can penetrate the rear end of the connector sleeve (110) in the axial direction and come into contact with the first connector terminal (120).

[0041] As illustrated in FIGS. 1 and 3, the second connector (200) is configured to include a connector housing (210), a second connector terminal (220), and a film layer pusher (230).

[0042] The connector housing (210) may be formed in a cylindrical shape with one end open and the other end closed. The connector housing (210) is formed with one end open along the longitudinal direction of the second connector terminal (220). The connector housing (210) has a second opening (211) at one end for insertion of the connector sleeve (110).

[0043] The second connector terminal (220) is positioned inside the connector housing (210). The second connector terminal (220) is positioned inside the connector housing (210) with one side fixed to the connector housing (210). The second connector terminal (220) extends long in the axial direction of the connector housing (210). The second connector terminal (220) may be positioned in the central part of the connector housing (210) with respect to the radial direction of the connector housing (210).

[0044] This second connector terminal (220) is formed in a cylindrical shape into which the first connector terminal (120) can be inserted. By inserting the first connector terminal (120) into the inner side of the second connector terminal (220) and making contact with the second connector terminal (220), the video signal transmitted to the first connector terminal (120) through the connector cable (150) can be transmitted from the first connector terminal (120) to the second connector terminal (220).

[0045] Meanwhile, the connector housing (210) is formed to have an inner diameter larger than the outer diameter of the connector sleeve (110) for easy connection of the connectors (100, 200). Additionally, the inner diameter of the connector housing (210) is larger than the outer diameter of the non-conductive film layer (130) coated on the outer surface of the connector sleeve (110).

[0046] For example, if the outer diameter of the connector sleeve (110) is 3.8 mm, the inner diameter of the connector housing (210) may be 6.7 mm, and the outer diameter of the non-conductive film layer (130) may be set to a value greater than 3.8 mm and less than 6.7 mm. The outer diameter of the non-conductive film layer (130) is determined according to the radial thickness (i.e., coating thickness) of the non-conductive film layer (130), and the method for determining the radial thickness of the non-conductive film layer (130) will be described later.

[0047] As the inner diameter of the connector housing (210) is larger than the outer diameter of the connector sleeve (110), when the connector sleeve (110) is inserted into the connector housing (210), a void portion (240) is formed as a space between the inner surface of the connector housing (210) and the outer surface of the connector sleeve (110).

[0048] The above-mentioned void portion (240) can be divided into a front void portion (241) and a rear void portion (242) through a film layer pusher (230).

[0049] The film layer pusher (230) is provided in a protruding form on the inner circumference of the connector housing (210). The film layer pusher (230) is formed to extend continuously in the circumferential direction of the connector housing (210). The film layer pusher (230) is formed in a ring shape on the inner circumference of the connector housing (210).

[0050] The film layer pusher (230) is formed to protrude radially toward the second connector terminal (220) of the connector housing (210). The film layer pusher (230) is positioned in the axial center of the connector housing (210). The film layer pusher (230) is formed integrally with the connector housing (210). Additionally, the film layer pusher (230) may be formed of the same material as the connector housing (210). For example, the film layer pusher (230) may be formed of stainless steel.

[0051] This film layer pusher (230) has an inner diameter smaller than the outer diameter of the non-conductive film layer (130) in order to relatively push out the peel portion (131) of the non-conductive film layer (130) when the connector sleeve (110) is inserted into the connector housing (210). That is, the inner diameter of the film layer pusher (230) is smaller than the outer diameter of the non-conductive film layer (130).

[0052] The film layer pusher (230) is formed to have a minimum radial width so as to act as a guide for the connector sleeve (110) when the first connector (100) and the second connector (200) are connected, and to minimize mechanical interference with the connector sleeve (110). Additionally, the film layer pusher (230) is formed to have a minimum clearance from the connector sleeve (110) so as to facilitate filling of the non-conductive film layer (130) into the front void (241). The radial width is based on the radial direction of the connector housing (210).

[0053] The radial width of the film layer pusher (230) may be smaller than the radial width of the front gap (241). For example, if the radial width of the front gap (241) is 1.2 mm, the radial width of the film layer pusher (230) may be 1.0 mm. In this case, the connector sleeve (110) and the film layer pusher (230) have a clearance of 0.2 mm.

[0054] The front gap (241) is positioned in front of the film layer pusher (230), and the rear gap (242) is positioned behind the film layer pusher (230). Specifically, based on the direction in which the connector sleeve (110) is inserted into the connector housing (210), the front gap (241) is positioned in front of the film layer pusher (230), and the rear gap (242) is positioned behind the film layer pusher (230). More specifically, the front gap (241) is a gap between the second opening (211) of the connector housing (210) and the film layer pusher (230).

[0055] The above film layer pusher (230) blocks the entry of the non-conductive film layer (130) when contact with the non-conductive film layer (130) begins when the connector sleeve (110) is inserted into the connector housing (210). Accordingly, the film layer pusher (230) acts to relatively push out the peel portion (131) of the non-conductive film layer (130) when the connector sleeve (110) is inserted into the connector housing (210).

[0056] The peeled portion (131) of the non-conductive film layer (130) is separated from the outer surface of the connector sleeve (110) as it is pushed by the film layer pusher (230) as the connector sleeve (110) enters the connector housing (210). The peeled portion (131) of the non-conductive film layer (130) separated from the outer surface of the connector sleeve (110) is moved toward the front void portion (241) and fills the front void portion (241) as shown in FIGS. 4 and 5.

[0057] At this time, the film layer stopper (140) prevents the peeled portion (131) of the non-conductive film layer (130) from leaking out to the outside of the front void portion (241), thereby ensuring that the front void portion (241) is completely filled by the non-conductive film layer (130).

[0058] When the first connector (100) and the second connector (200) are connected, the front gap (241) is completely filled by the non-conductive film layer (130), thereby eliminating the gap between the connector housing (210) and the connector sleeve (110) and preventing radial movement of the connector sleeve (110) caused by the gap.

[0059] More specifically, during the process of inserting the connector sleeve (110) into the connector housing (210) for connecting the first connector (100) and the second connector (200), the peeled portion (131) of the non-conductive film layer (130) is separated from the outer surface of the connector sleeve (110) by the film layer pusher (230) and moved to the front void portion (241). At this time, the peeled portion (131) of the non-conductive film layer (130) that has moved to the front void portion (241) fills the space between the outer surface of the non-peeled portion (132) that remains coated on the outer surface of the connector sleeve (110) and the inner surface of the connector housing (210). As a result, the front void portion (241) is completely filled with the non-conductive film layer (130) when the connection of the first connector (100) and the second connector (200) is completed.

[0060] In order to ensure that the front gap (241) is completely filled with the non-conductive film layer (130) when the first connector (100) and the second connector (200) are connected, the radial thickness (t) of the non-conductive film layer (130) film ) is determined as shown in Equation 3 below. This is because the volume (A1) of the front void (241) is calculated as shown in Equation 1 below, and the required volume (A2) of the non-conductive film layer (130) to fill the front void (241) is calculated as shown in Equation 2 below, and the required volume (A2) of the non-conductive film layer (130) must be the same as the volume (A1) of the front void (241).

[0061] Equation 1: A1 = π×h'×(a 2 - b 2 )

[0062] Equation 2: A2 = 2π×b×h×t film ÷ Filling rate film

[0063] Equation 3:

[0064] Referring to FIG. 1, h' is the distance from the second opening (211) of the connector housing (210) to the film layer pusher (230), a is the inner diameter of the connector housing (210), b is the outer diameter of the connector sleeve (110), h is the axial length of the connector sleeve (110), and the filling rate film is the filling rate of the non-conductive film layer (130) for the front void portion (241).

[0065] Since some of the peeled portion (131) of the non-conductive film layer (130) may not be separated from the connector sleeve (110) due to the gap between the connector sleeve (110) and the film layer pusher (230), the filling rate film The value is adjusted so that the front void (241) is completely filled with the non-conductive film layer (130).

[0066] As shown in FIG. 1, before the first connector (100) and the second connector (200) are connected, the radial thickness of the non-conductive film layer (130) has a value smaller than the radial width of the front gap (241). As shown in FIG. 4 and FIG. 5, after the first connector (100) and the second connector (200) are connected, the radial thickness of the non-conductive film layer (130) has a value equal to the radial width of the front gap (241).

[0067] In the connector assembly for a video transmission cable of the present invention configured as described above, the front gap (241) is filled with a non-conductive film layer (130) during the process in which the connector sleeve (110) is inserted into the connector housing (210) for connecting the first connector (100) and the second connector (200), and when the connection between the first connector (100) and the second connector (200) is completed, the front gap (241) is completely filled with the non-conductive film layer (130), thereby eliminating the gap between the connector housing (210) and the connector sleeve (110). As a result, the connector assembly for a video transmission cable can increase the rigidity of the connection and stably maintain the contact state of the connector terminals (120, 220) even when vibration and shock occur in the vehicle, thereby preventing video signal transmission errors caused by poor contact of the connector terminals (120, 220).

[0068] Here, the second connector (200) may be a connector of a video receiver that receives a video signal transmitted from a connector cable (150) through a connector assembly as described above. The video receiver may output and store the received video signal. For example, the second connector (200) may be a female connector provided in a controller of the video receiver.

Furthermore, the scope of the present invention is not limited to the embodiments described above, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims are also included within the scope of the present invention.
