Description

Technical Field

[0001] This invention relates to cable connectors for connecting electronic devices such as vehicle-mounted equipment to cables, and methods for assembling the same. Background Technology

[0002] In the past, electronic devices such as vehicle camera modules were connected to cables consisting of multiple wires using cable connectors (for example, see Patent Document 1).

[0003] This type of cable connector has contacts that connect to each wire and an insulator that holds each contact. After the core wires of each wire are crimped to the contacts, each contact is pressed into the insulator, thereby holding multiple contacts in the insulator.

[0004] In addition, in this type of cable connector, when the contacts are arranged in a longitudinal and transverse direction on the end face, it is difficult to press multiple contacts at the same time. Therefore, each contact is crimped with the core wire of each wire, and after crimping, the insulator is pressed in separately.

[0008] The problem that the invention aims to solve

[0009] However, in the prior art as described above, since the core wire of the wire is crimped to each contact and inserted into the insulator, the assembly time increases as the number of contacts increases, resulting in problems such as deterioration of work efficiency.

[0010] Furthermore, in this type of existing cable connector, because each contact is crimped with a wire and pressed into the insulator, there is unevenness in the assembly, resulting in unstable distances between contacts and between cable crimped parts, which causes individual differences in transmission performance.

[0011] Therefore, the present invention addresses these prior problems and aims to provide a cable connector and its assembly method that can be assembled efficiently, crimped with cables and contacts in a stable state, and exhibits excellent transmission performance.

[0012] Solution for solving the problem

[0013] The invention described in Solution 1, which addresses the existing problems as described above, is characterized in that the cable connector comprises: a plurality of contacts respectively connected to each wire of a cable consisting of a plurality of wires; and an insulator holding the plurality of contacts. In the cable connector, the insulator comprises: a front insulator consisting of a plurality of segments whose side portions are joined to each other; and a rear insulator connected to and linked to the rear of the front insulator and the segments. The contacts are embedded in the segments and integral with them in a state where a connecting portion connected to the wire protrudes from the rear end face of the segments.

[0014] In addition to the structure of Scheme 1, the invention described in Scheme 2 includes the following features: a base portion extending from the contact base portion; and a crimping piece supported on the side edge of the base portion and pressed against the base portion side at its front end. The core wire of the wire inserted between the base portion and the crimping piece is crimped to the base portion by the crimping piece. The crimping piece side faces the mating surface side of the split body or the outer side side opposite to the mating surface.

[0015] In addition to the structure of Scheme 1 or 2, the invention described in Scheme 3 has the following features: the front insulator has a keyway portion formed through the space between the split bodies; the rear insulator has a connecting key portion that protrudes from the front end face and engages with the keyway portion; and on one side of the connecting key portion or the inner side of the keyway portion, there is a engaging protrusion that protrudes from the side or the inner side and engages with an engaging recess formed on the inner side of the keyway or the side of the connecting key portion.

[0016] In addition to the structure of any one of Schemes 1 to 3, the rear insulator of Scheme 4 includes: a connecting portion receiving portion with an opening on its outer side and for receiving the connecting portions respectively; and a blocking wall separating the connecting portion receiving portions.

[0017] The invention described in Scheme 5 is characterized in that, in the assembly method of the cable connector, the cable connector comprises: a plurality of contacts respectively connected to each wire of a cable composed of a plurality of wires; and an insulator holding the plurality of contacts. In the assembly method, a plurality of segments are integrally formed such that the connection portions for connecting the contacts to the wires protrude from the rear end face. After the wires are respectively connected to the contacts of each segment, a rear insulator is disposed behind the segment while the segment is moved in a direction of mutual separation. Then, the rear insulator is connected to the interlocking plurality of segments, thereby integrating the segments.

[0018] In addition to the structure of Scheme 5, the invention described in Scheme 6 has a base portion extending from the connector body and a pair of crimping tabs supported on both sides of the base portion, such that the opening between the pair of crimping tabs opens to the outer side of one of the split bodies, so that the core wire of the wire is simultaneously crimped to multiple connecting portions constituting the contacts of each split body.

[0019] The effects of the invention

[0020] The cable connector of the present invention, by having the structure of embodiment 1, eliminates the need to press the contacts into the insulator and stabilizes the distance between contacts and between connecting parts, thereby improving transmission performance.

[0021] Furthermore, in this invention, by having the structure of Scheme 2, it is possible to simultaneously press multiple contacts and wires embedded in each segment, thereby reducing assembly time.

[0022] Furthermore, in this invention, by having the structure of Scheme 3, the split bodies can be appropriately connected to each other, and the front insulator and the rear insulator can be integrated.

[0023] Furthermore, in this invention, by having the structure of Scheme 4, the connection between the parts can be appropriately blocked.

[0024] Furthermore, in this invention, by having the structure of Scheme 5, it is possible to connect the wire to the contact while integrating multiple contacts with the dividing body, without pressing the contact into the insulator, and to stabilize the distance between the contacts and the connection parts, thereby improving the transmission performance.

[0025] Furthermore, in this invention, by having the structure of Scheme 6, it is possible to simultaneously press multiple contacts and wires embedded in each segment, thereby reducing assembly time. Attached Figure Description

Detailed Implementation

[0038] The following is based on Figures 1 to 7 The embodiments shown illustrate implementations of the cable connector of the present invention. Furthermore, in the figures, symbol 1 represents a cable connector.

[0039] Furthermore, in this embodiment, for convenience, the connector side of the cable connector 1 is defined as "front", the side connected to the cable 2 is defined as "rear", a direction of the front face is defined as "longitudinal", and a direction orthogonal to the longitudinal direction is defined as "lateral".

[0040] The cable connector 1 has a connector body 3 consisting of multiple contacts 4, 4... and an insulator 5 that holds the multiple contacts 4, 4... The multiple contacts 4, 4... are respectively connected to each wire 21, 21... of the cable 2 consisting of multiple wires 21, 21... The connector body 1 is housed in an outer cover 7 while the outer side of the connector body 3 and the end of the cable 2 connected to the connector body 3 is covered by a shielding member 6.

[0041] like Figure 4 As shown, in cable 2, multiple wires 21, 21... (four in this embodiment) are bundled by outer sheath 22. The outer sheath 22 at the front end is peeled off, and the covering layer at the front end of each exposed wire 21, 21... is peeled off, and the front end of the core wire 23 is exposed. The core wire 23 is connected to the contacts 4, 4...

[0042] The outer cover 7 is made of synthetic resin and includes: a hollow box-shaped cover body 71 that houses the connector body 3 covered by the shielding component 6; a sealing gasket (not shown) that closes the rear end of the cover body 71; and a rear cover 72 that fits into the rear end of the cover body 71.

[0043] The cover body 71 includes: a connector storage portion 711 that opens to the front end face; a sealing gasket storage portion (not shown) that communicates with the connector storage portion 711 and opens to the rear end face; and a flange portion 712 that extends from the outer peripheral surface. The connector storage portion 711 stores the connector body 3 covered by the shielding member 6, and the sealing gasket storage portion stores the sealing gasket that fits onto the outside of the cable 2. The rear end opening of the sealing gasket storage portion is closed by the rear cover 72.

[0044] The shielding component 6 is formed of a conductive material into a square tube shape with an open front end, and a fixing component 61 for holding the outer sheath 22 of the cable 2 is supported on the rear edge of its peripheral wall.

[0045] like Figure 4 As shown, the insulator 5 includes: a front insulator 8 consisting of a plurality of (in this embodiment, a pair) segments 81, 81 joined together; and a rear insulator 9 connected to and linked to the rear of the front insulator 8 and the segments 81, 81, wherein a plurality of contacts 4, 4 are integrally held in each of the segments 81, 81.

[0046] like Figures 5(a) to 5(d) As shown, the rear insulator 9 is integrally formed from insulating synthetic resin and has a rectangular body 91 and a connecting key 92 protruding to the front end face of the body 91, i.e., the side of the front insulator 8.

[0047] The torso 91 has groove-shaped connecting portion storage portions 93 and 93 that are open on the outer side of the transverse side, i.e. the direction in which the two segments 81 and 81 can be separated from each other, and are through the front and back. Each connecting portion storage portion 93 and 93 is separated by a blocking wall that constitutes the wall portion of the torso 91.

[0048] As shown in Figure 5(d), the connecting key 92 is formed as a flat plate that is longer in the transverse direction, i.e., between the split bodies 81, 81, and has engaging protrusions 94, 94 that protrude from the side portions of the transverse ends, and is formed in an I-shape in the transverse cross section.

[0049] The engaging protrusions 94, 94 protrude from the side portion in a longitudinal direction, that is, in a direction orthogonal to the direction between the dividing bodies 81, 81, forming a continuous protrusion in the front-to-back direction.

[0050] like Figures 6(a) to 6(c) As shown, the segment 81, 81 are formed into a longitudinally elongated cuboid shape by longitudinally dividing the front insulator 8. Multiple contacts 4, 4... are integrally assembled in the longitudinal direction of each segment 81, 81 by embedding and forming.

[0051] Regarding the two segments 81, 81, their inner side faces orthogonal to the front end face are joined together to form a cubic front insulator 8. In the front insulator 8, multiple contacts 4, 4... (in this embodiment, four) are arranged longitudinally and transversely relative to the front end face.

[0052] In addition, each of the segmented bodies 81 and 81 has a concave groove 82a and 82a at the center of its rear end, which is oriented laterally, i.e., between the segmented bodies 81 and 81. The two grooves 82a and 82a are connected by joining the two segmented bodies 81 and 81, thereby forming a keyway 82 that penetrates between the segmented bodies 81 and 81.

[0053] The keyway portion 82 is formed to have the same or slightly deeper depth as the protrusion of the connecting key portion 92. When the rear insulator 9 is connected to the front insulator 8, the front end face of the rear insulator 9 abuts against the rear end face of the front insulator 8.

[0054] Therefore, the front insulator 8 is connected to the rear insulator 9, so that the front end faces of the two segments 81, 81 form the same plane, and the contacts 4, 4... held in each segment 81, 81 are also positioned in the predetermined position.

[0055] On the other hand, at both ends of the keyway portion 82, that is, on the inner side of the outer end of each groove recess 82a, 82a, there are engaging recesses 83, 83 that engage with engaging protrusions 94, 94, and the keyway portion 82 is formed in a cross-section of horizontal I-shape corresponding to the shape of the connecting key portion 92.

[0056] The engaging recesses 83, 83 are recessed in the longitudinal direction, that is, in the direction orthogonal to the inner surface of the keyway portion 82, forming a groove shape that is continuous with the depth direction of the keyway portion 82.

[0057] Furthermore, by connecting the key portion 92 and the keyway portion 82, and engaging the engagement protrusions 94 and 94 and engaging the engagement recesses 83 and 83, the two segments 81 and 81 are clamped between the engaging protrusions 94 and 94 that are laterally opposed, and the movement of the two segments 81 and 81 in the direction of separation is restricted, thereby integrating them into a joined state.

[0058] like Figure 7 As shown, the contacts 4, 4... are formed as one piece from a conductive metal plate and have: a contact base 41 embedded in the divider 81; a contact portion 42 supported at one end of the contact base 41; and a connecting portion 43 supported at the other end of the contact base 41.

[0059] The contacts 4, 4... are formed as a group of symmetrically shaped components that are adjacent to each other in the longitudinal direction. The group of contacts 4, 4 is assembled into the segment 81 by embedding. With the contact portion 42 exposed to the front end face of the segment 81, 81 and the connecting portion 43 protruding from the rear end face of the segment 81, 81, the contact base 41 is embedded in the segment 81, 81.

[0060] The contact base 41 has a slender plate-shaped main body plate 411 and support plates 412 and 413 extending obliquely in the longitudinal direction from one end of the main body plate 411 on the same plane as the main body plate 411. The contact portion 42 is supported by the support plates 412 and 413.

[0061] Each of the support plates 412 and 413 of a set of contacts 4, 4 is supported such that the contact portion 42 extends laterally in a direction that is separated from each other, and the contact portions 42 are adjacent in the longitudinal direction.

[0062] The contact portion 42 includes: a supported piece 421 bent from the front end of the support pieces 412, 413 in a direction orthogonal to the support pieces 412, 413; and a rectangular plate-shaped contact piece 422 supported on the supported piece 421, configured to be exposed parallel to its front end face when assembled with the split body 81, 81.

[0063] The connecting portion 43 includes: a base portion 431 extending from the contact base portion 41; and crimping plates 432, 432 supported on the side edge of the base portion 431, which are pressed together by rolling the crimping plates 432, 432 toward the base portion 431. The core wire 23 of the wires 21, 21... inserted between the base portion 431 and the crimping plates 432, 432 is crimped to the base portion 431 by the two crimping plates 432, 432.

[0064] The crimping tabs 432, 432 of the connecting portion 43 face the outer side opposite to the mating surface side of the dividing body 81, and the connecting portions 43 of a set of contacts 4, 4... of each dividing body 81, 81 face the same direction, with the crimping tabs 432, 432 open between them.

[0065] That is, a set of contacts 4, 4... held in the divider 81, 81 are pressed together from the same direction.

[0066] The following is based on Figure 8~ Figure 10 The assembly method of the cable connector described above will be explained. Furthermore, for structures identical to those in the embodiments described above, the same symbols will be used and descriptions will be omitted.

[0067] First, after passing the cable 2 through the rear cover 72, fit the sealing gasket (not shown) onto the outside of the outer sheath 22 of the cable 2, and move the rear cover 72 and the sealing gasket toward the rear of the cable 2 to facilitate the operation.

[0068] Next, the outer sheath 22 of cable 2 is stripped to expose the front ends of each wire 21, 21..., and the covering layer at the front end of each wire 21, 21... is stripped to expose the core wire 23.

[0069] In addition, as a preparation, with the contact portion 42 exposed to the front end face and the connecting portion 43 protruding from the rear end face, multiple (in this embodiment, a pair) segmented bodies 81, 81, formed by insert molding are used to create multiple contacts 4, 4... integrated into one unit.

[0070] Next, as shown in Figures 8(a), 9(a), and 9(b), the core wires 23 of each wire 21 are crimped to the contacts 4 and 4 held in the divider 81, and the wires 21 and 21 are connected to the contacts 4 and 4.

[0071] Specifically, the base portion 431 of a set of contacts 4, 4 held on one side of the split body 81 is placed on the support platform 11, 11, and the core wire 23 of the wires 21, 21... is inserted between the crimping plates 432, 432. In addition, the other wires 21, 21... are arranged in positions such as bends that do not interfere with the support platform 11, 11.

[0072] Next, as shown in Figures 9(a) and 9(b), the crimping clamp (crimper) 12 is lowered, and the crimping clamp (crimper) 12 is used to press the crimping pieces 432, 432 and roll the crimping pieces 432, 432 into the inside, and the two crimping pieces 432, 432 press the core wire 23 and crimp it to the base part 431.

[0073] At this time, as shown in FIG9(b), all the contacts 4, 4 held in the split body 81 are configured at the same height and in the same orientation (the side opposite to the mating surface), so that the core wire 23 of all the contacts 4, 4 held in the split body 81 and the connecting part 43 can be crimped at the same time.

[0074] Next, the core wires 23 of each wire 21, 21... are similarly crimped to the contacts 4, 4... held on the other side of the divider 81, connecting the wires 21, 21 to the contacts 4, 4.

[0075] Next, as shown in FIG8(b), with the split bodies 81, 81 connected to the wires 21, 21 moved in a direction of separation from each other, the connecting key 92 side is facing the front insulator 8 side, and the rear insulator 9 is inserted from between the two split bodies 81, 81 to the rear of the split bodies 81, 81.

[0076] Furthermore, as shown in Figure 8(c), Figure 10 As shown, wires 21, 21... are embedded in the connecting portion storage portions 93, 93 of the body 91 of the rear insulator 9, and the two segments 81, 81 are joined together.

[0077] The front insulator 8 is joined together by the dividers 81, 81, so that the grooves on the rear face are connected by the recesses 82a, 82a, forming a keyway portion 82 that is continuous in the transverse direction.

[0078] In this state, the rear insulator 9 is pushed into the front insulator 8 side, so that the connecting key 92 and the keyway 82 are engaged, and the front end face of the body 91 abuts against the rear end faces of the two segments 81, 81.

[0079] Furthermore, by connecting the key portion 92 and the keyway portion 82, and engaging the protrusions 94 and 94 and engaging the recesses 83 and 83, the movement of the two segments 81 and 81 in the direction of separation is restricted, and the two segments 81 and 81 are integrated.

[0080] In addition, along with the connection between the front insulator 8 and the rear insulator 9, the connecting portions 43 of each contact 4, 4... protruding from the rear end face of each segment 81, 81, and the wires 21, 21... connected to the connecting portions 43 are housed in the connecting portion housing portions 93, 93 formed in the body 91 of the rear insulator 9.

[0081] Next, as shown in Figure 8(d), the shielding component 6 is placed over the outside of the connector body 3 of the connecting cable 2, so that the outer sheath 22 of the cable 2 is held by the fixing component 61, and the shielding component 6 is fixed to the outside of the connector body 3.

[0082] Furthermore, the connector body 3 covered by the shielding component 6 is inserted into the connector storage portion 711 of the cover body 71, so that the sealing gasket moves forward towards the cable 2 and is stored in the sealing gasket storage portion of the cover body 71, and the rear cover 72 is used to close its rear, thereby completing the assembly.

[0083] In the cable connector 1 constructed in this way, multiple contacts 4, 4... are integrated with each segment 81, 81 by embedding and molding, thereby eliminating the need to insert the contacts 4, 4... into the insulator 5 and reducing the time required for this part.

[0084] Furthermore, in this cable connector 1, even when the contacts 4, 4... are arranged in multiple longitudinal and transverse directions relative to the front end face, since the front insulator 8 is divided into multiple segments 81, 81, and the crimping tabs 432, 432 of all the contacts 4, 4... held in the segments 81, 81 face the outer side of the segments 81, 81 opposite to the mating surface, the crimping operation of the wires 21, 21... relative to each contact 4, 4... held in the segments 81, 81 can be performed simultaneously, thus reducing the time required for this part.

[0085] Furthermore, in this cable connector 1, by using embedded molding to assemble multiple contacts 4, 4... in the split bodies 81, 81, the distance (longitudinal distance) between each contact 4, 4... in the split bodies 81, 81 is kept stable. The front insulator 8 is connected to the rear insulator 9, and by restricting the movement of the joined split bodies 81, 81 in the separation direction, the distance (lateral distance) between the contacts 4, 4... in each split body 81, 81 is also kept stable.

[0086] Furthermore, in this cable connector 1, by having the front end face of the rear insulator 9 abut against the rear end face of each segment 81, 81, the front end faces of the two segments 81, 81 are positioned in such a way that their relative positions in the front-rear direction are on the same plane, and the relative positions of the contacts 4, 4... of the segments 81, 81 in the front-rear direction are also kept stable.

[0087] Therefore, in this cable connector 1, the relative positional relationship of the multiple contacts 4, 4... held in the insulator 5 can always be kept in a stable state, thereby ensuring stable transmission performance.

[0088] Furthermore, in this cable connector 1, the connecting portions 43 of each contact 4, 4... protruding from the rear end face of the split bodies 81, 81, and the wires 21, 21... connected to the connecting portions 43 are housed in the connecting portion housing portions 93, 93 formed in the body 91 of the rear insulator 9. The connecting portion housing portions 93, 93 are separated by a shielding wall, thus suppressing signal interference between the wires 21, 21....

[0089] Furthermore, in the above embodiment, the structure in which the contact portion 42 of the contacts 4, 4... is formed as a flat plate and exposed to the front end face of the front insulator 8 is described as an example. However, the shape of the contact portion 42 is not limited to this. For example, it can also be a plug-in shape or a pin shape.

[0090] Furthermore, in the above embodiments, an example of connecting the front insulator 8 and the rear insulator 9 by fitting the connecting key portion 92 and the keyway portion 82 has been described. However, the shape of the connecting portion is not limited to this. For example, multiple pin-shaped protrusions may be provided on the front end face of the body 91 of the rear insulator 9, and these protrusions may be inserted into pin holes that open to the rear end faces of each segment 81, 81.

[0091] Furthermore, in the above embodiments, the case of the pressure contact heads 4, 4... and the wires 21, 21... has been described, but the connection between the contacts 4, 4... and the wires 21, 21... is not limited to this. For example, they can also be connected by soldering, spot welding, or conductive adhesive.
