Description

Technical field

[0001] The present invention relates to a split sealing mold structure for a combination cable, in particular a split sealing mold structure for a combination cable, wherein cables connected to a wheel speed sensor or an electronic parking brake are integrally fixed in a separated state and the inner surface of the protective tube is formed into an ellipse to prevent the inflow of a molding compound. State of the art

[0002] In general, a vehicle's electronic parking brake (EPB) is a braking device that automatically engages the brakes when the vehicle is stopped and automatically releases them after the brake pedal is pressed during startup. Because it can brake without the need to press the brake pedal, the EPB is being used in an increasing number of vehicles.

[0003] A motor drives the EPB (Electronic Parking Brake) to engage or disengage a disc, thereby applying or releasing the brake. An EPB cable is connected to the motor via a connector to supply electrical power. A wheel speed sensor (WSS) is also located around the EPB to detect wheel speeds after ABS activation. The WSS transmits and receives detection signals via a cable.

[0004] In the past, the EPB cable and the WSS cable in a vehicle were separate and connected to the engine and WSS, respectively. Because the cables were routed separately, it was difficult to organize them neatly; consequently, the vehicle's overall quality was compromised.

[0005] Furthermore, to solve the aforementioned problem, an EPB cable and a WSS cable were coupled and connected. However, no suitable structure was provided at the dividing point between the motor and the WSS to separate the cables.

[0006] US 2 933 550 A deals with an electrical cable assembly with one or more electrical conductors, with a plurality of sleeves surrounding a portion of the electrical conductors, wherein a uniform mass surrounds an end portion of the sleeve and joins the electrical conductor and the sleeve together.

[0008] CN 2 04 155 655 U deals with a cable harness with a first connecting tube, a second connecting tube and a third connecting tube, wherein a single cable is guided through the second and third connecting tubes.

[0009] JP 2005 - 294 132 A discloses an outer shaped cable harness comprising an outer component made of a thermoplastic elastomer, which is arranged by melting on a circumferential surface of a wire coating material of an olefin resin coated wire.

[0010] Therefore, it is necessary to mitigate the aforementioned problem.

Therefore, these terms should be defined based on the entire content of this description.

Fig. Figure 2 shows an enlarged oblique view of the split sealing mold structure of a combination cable, as described in an embodiment of the present invention.

Fig. Figure 5 shows a sectional view of the state in which the protective tube is provided on the first cable in an embodiment of the present invention. Fig. Figure 6 shows the state in which a cord feedthrough section is formed on the dividing mold section in the divided sealing mold structure for a combination cable according to the present invention.

[0032] Fig. Figure 7 shows a flowchart of the process for manufacturing a split sealing mold structure of a combination cable, as described in one embodiment of the present invention.

[0033] As in the Fig. Figures 1 to 6 show a split sealing mold structure of a combination cable, which is described in an embodiment of the present invention, comprising the first cable (10), the second cable (20), the connector (30), the split mold section (40), the connector mold section (50) and the protective tube (60).

[0034] As in the Fig. 1 and Fig. As shown in Figure 2, after disconnecting the first cable (10) from the combination cable (2), an electric parking brake (EPB) is connected to its end. The first cable (10) is exposed by removing the outer sheath (4) of the combination cable (2). The first cable (10) comprises two offset turns, which can be configured relative to each other.

[0035] After disconnecting the second cable (20) from the combination cable (2), the wheel speed sensor (WSS) (22) or the WSS extension cable connector (24) is connected to its end. As shown in Fig. As shown in Figure 3, the second cable (20) is exposed to the outside by removing the outer sheath (4) of the combination cable (2). In this case, the second cable (20) can also have its inner sheath (6) on the inner surface of the outer sheath (4); thus, the two turn offsets of the second cable (20) can only be exposed once the inner sheath (6) has been removed. The WSS (22) is functionally connected to the two turn offsets of the second cable (20). As shown in Figure 3, the second cable (20) is exposed to the inner sheath (6) of the combination cable (20). Fig. As shown in Figure 6, the WSS extension cable connector (24) can also be connected to the end of the second cable (20).

[0036] The connector (30) is provided at the end of the first cable (10), thus enabling operation of the EPB. After connecting the connector (30) to the end of the first cable (10), it is secured using the connector section (50) described below.

[0037] The splitting form section (40) is a form structure that is formed between the first cable (10) and the second cable (20) in the split section and holds the first cable (10) and the second cable (20) in a split state. By forming, the splitting form section (40) integrally fixes the combination cable (2), the second cable (20), which is formed by connecting it in a straight line, and the splitting section of the first cable (10), which bends into a ¬-shape, so that the combination cable (2) holds the first cable (10) and the second cable (20) in a split state.

[0038] The splitting section (40) comprises the following structures: the integral section (42), which surrounds and secures the outer surface of the outer sheath (4) of the combination cable (2); the splitting section (44), which is formed by bending towards the side of the first cable (10) exposed to the integral section (42); and the second splitting section (46), which is formed by straightening towards the side of the second cable (20) exposed to the integral section (42). In this case, the diameter of the first splitting section (44) remains almost the same from one end to the other. This ensures that the first splitting section (44) securely secures one end of the protective tube (60) and holds the first cable (10) in a bent position. Furthermore, the diameter of the second splitting section (46) gradually increases from one end to the other.The diameter of the second cable (20) is smaller than the diameter of the protective conduit (60) surrounding the first cable (10). Therefore, a diameter corresponding to that of the protective conduit (60) surrounding the first split section (44) is maintained. To improve the flexibility of the second cable (20), its diameter is designed to gradually decrease towards its end. The split section (40) surrounds the first cable (10) and the second cable (20), which are separate, and the combination cable (2), which is not separate, thus preventing the ingress of any foreign substances, such as moisture.

[0039] The connector forming section (50) is a structure that forms the connection between the connector (30) and the first cable (10). The connector forming section (50) can be formed simultaneously with, before, or after the split forming section (40). The connector forming section (50) bends into a ¬-shape; thus, when the connector (30) is in place, the first cable (10) can bend to a predetermined degree and direction. The connector forming section (50) is approximately at a right angle. The connector forming section (50) surrounds the separated first cable (10) and part of the connector (30), thereby preventing the ingress of foreign substances, such as moisture.

[0040] As in the Fig. 4 and Fig. As shown in Figure 5, the protective tube (60) is a structure that protects the first cable (10) with its ends fixed to the splitting mold section (40) and the connector mold section (50), respectively. The outer surface of the protective tube (60) is circular. The protective tube (60) can be made of TPU rubber (TPU - thermoplastic polyurethane). The protective tube (60) can also be made of other types of rubber or soft synthetic resin. As shown in Fig. As shown in Figure 5, the inner surface (62) of the protective tube (60) can be elliptical, and the protective tube fits snugly against the outer surface of the first cable (10), which has two turn offsets, thus preventing the inflow of a molding compound. If the split molding section (40) and the connector molding section (50) are each formed on one side of the protective tube (60), it is thus possible to prevent a molding compound from flowing into the interior of the protective tube (60) through the open spaces on both sides of the protective tube (60). In this case, the inner surface of the protective tube (60) is an ellipse (62). Due to friction, it can be difficult to insert the first cable (10), which has two turn offsets. However, the protective tube (60) alone can block the inflow of a molding compound without the need for any additional blocking component (not shown in the figure). Thus, the number of components can be reduced.

[0041] As in Fig. As shown in Figure 6, the cord guide section (80) for installing the bracket (90) is formed and integrated on the outer surface of the dividing mold section (40). Fig. As shown in Figure 1, the number of components can increase when the cord feed-through section (80) is arranged on the division form section (40) and in any other position on the combination cable (2). If, as in Fig. As shown in Figure 6, if the cord guide section (80) is integrated into the dividing mold section (40), the number of components and the manufacturing costs can be reduced. If the cord guide section (80) is provided on the integral section (42) of the dividing mold section (40), it is advantageous to install the support (90) in this case.

[0042] With reference to Fig.7 The specific sequence of the method for manufacturing a split sealing mold structure for a combination cable according to the present invention is described in detail below.

[0043] Initially, the method for producing a split sealing mold structure for a combination cable according to the present invention comprises the following steps: exposing and splitting (S10), arranging the sheathing (S20), arranging the connector (S30), arranging the WSS (S40), forming the split mold section (S50) and forming the connector mold section (S60).

[0044] The exposing and separating step (S10) is the step of removing the outer sheath (4) of the combination cable (2) to expose and separate portions of the first cable (10) and the second cable (20). In this case, part of the inner sheath (6) may remain on the second cable (20).

[0045] The sheathing application step (S20) involves applying the sheathing to the outer surface of the separated first cable (10). The outer surface of the sheathing is circular, and the inner surface (62) of the sheathing is elliptical. Therefore, the side surface of the sheathing lies as close as possible to the first cable (10). During the forming of the split section (40) and the connector section (50), measures can be taken to prevent molding compound from flowing into the interior of the protective tube (60).

[0046] The step of arranging the connector (S30) is the step of arranging the EPB connector (30) at the end of the first cable (10).

[0047] The step of arranging the WSS (S40) is the step of arranging the WSS (22) at the end of the second cable (20).

[0048] The step of forming the split section (S50) is the step of surrounding the split section between the first cable (10) and the second cable (20) and one end of the protective conduit (60) to form the split section (40). The split section (40) simultaneously surrounds the split section between the first cable (10) and the second cable (20) and part of the combination cable (2), thereby preventing the ingress of any foreign substances, such as moisture.

[0049] The step of forming (S60) the connector section (50) is the step of surrounding the connection section between the connector (30) and the first cable (10) and the other end of the protective tube (60) to form the connector section (50). The connector section (50) bends into the shape of a "¬". The connector section (50) surrounds the first cable (10) and part of the connector (30), thereby preventing the ingress of foreign substances, such as moisture. [Description of reference symbols]
