Description

[Technical field]

[0001] The present invention relates to a connector. [Background technology]

[0002] A connector is provided with a metallic shield shell that covers a synthetic resin housing from the outside in order to prevent external noise from entering the terminal fittings and electric wires in the housing. In this connector, the shield shell is screwed to a mating metallic housing or the like with a metallic bolt, and external noise on the shield shell is released through the housing or the like. Since this connector employs such a screw-fastening structure, the head of the bolt protrudes to the outside. For this reason, conventional connectors are provided with a bolt cap that covers the head of the bolt to prevent the head from being exposed to water. For example, the connectors described in the following Patent Documents 1 to 6 are provided with a bolt cap that has a cap body that covers the head of the bolt and a co-fastening portion that is fastened together with the bolt.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a connector according to the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to this embodiment.

[0010] [Embodiment] One embodiment of a connector according to the present invention will be described with reference to FIGS.

[0011] Reference numeral 1 in Fig. 1 to Fig. 5 indicates a connector of this embodiment. This connector 1 is attached to an end of an electric wire We, and is electrically connected to a device (not shown) at the end of this electric wire We. This connector 1 is electrically connected to a mating terminal fitting 510 (Fig. 2) of a mating device 500, thereby electrically connecting the mating device 500 and the device at the end of the electric wire We. For example, in this case, the device at the end of the electric wire We is an inverter of a vehicle, and the mating device 500 is a rotating machine of the vehicle.

[0012] The connector 1 includes a terminal fitting 10, a housing 20, and a shield shell 30 (FIGS. 3 and 4).

[0013] The terminal fitting 10 is made of a conductive material such as metal. For example, the terminal fitting 10 is formed into a predetermined shape by press forming such as bending and cutting a base metal plate. The terminal fitting 10 is attached to an end of the electric wire We so as to be electrically connected to the electric wire We. The terminal fitting 10 is also physically and electrically connected to a mating terminal fitting 510. Thus, the terminal fitting 10 has a terminal connection portion 11 that is physically and electrically connected to a mating terminal connection portion 511 of the mating terminal fitting 510, and an electric wire connection portion 12 that is physically and electrically connected to the end of the electric wire We (FIG. 4).

[0014] The terminal connection portion 11 may be, for example, one that is fitted and connected to the counterpart terminal connection portion 511 of the counterpart terminal fitting 510, or one that is screwed and fixed to the counterpart terminal connection portion 511. The terminal connection portion 11 of this embodiment is formed to be fitted and connected to the counterpart terminal connection portion 511 in a fitting connection direction along the terminal insertion direction into the housing 20. Thus, one of the terminal connection portion 11 and the counterpart terminal connection portion 511 is formed in a female terminal shape, and the other is formed in a male terminal shape.

[0015] The terminal connection part 11 shown here is formed in a tubular female terminal shape into which the mating terminal connection part 511 is inserted in the terminal removal direction from the housing 20. This terminal connection part 11 is formed, for example, in a square tube shape or a cylindrical shape. Here, the terminal connection part 11 is formed in a square tube shape. Therefore, the mating terminal connection part 511 shown here is formed in a one-piece male terminal shape (so-called male tab shape) (FIG. 2).

[0016] The electric wire connection part 12 is physically and electrically connected to the core wire at the end of the electric wire We by, for example, crimping or welding. The electric wire connection part 12 shown here is crimped to the bare core wire by crimping two barrel pieces to the bare core wire.

[0017] The terminal fitting 10 shown in this example is formed in a straight shape with its terminal connection portion 11 and electric wire connection portion 12 arranged on a straight line. Therefore, the electric wire We is drawn out from the electric wire connection portion 12 in the extension direction of the terminal fitting 10 along the straight line. However, the terminal fitting 10 may be arranged such that the terminal connection portion 11 and the electric wire connection portion 12 are crossed, for example, by orthogonally arranging them.

[0018] The connector 1 shown here has three pairs of terminal fittings 10 and electric wires We.

[0019] The housing 20 is molded from an insulating material such as synthetic resin. The terminal fitting 10 and the electric wire We are housed inside the housing 20. The terminal fitting 10 is held in the housed state in the housing 20, and the electric wire We is pulled out from the inside to the outside.

[0020] In this housing 20, a terminal accommodating portion 21 for accommodating the terminal fitting 10 in the inner terminal accommodating chamber 20a is provided for each terminal fitting 10 (FIGS. 1, 3, and 4). This terminal accommodating portion 21 is formed in a rectangular tube shape, and the rectangular tube-shaped terminal connection portion 11 is accommodated in the inner terminal accommodating chamber 20a. In this terminal accommodating portion 21, the mating terminal connection portion 511 is inserted into the terminal accommodating chamber 20a from one opening in the cylindrical axis direction, and the mating terminal connection portion 511 is inserted into the terminal connection portion 11 in the terminal accommodating chamber 20a.

[0021] The housing 20 has a cylindrical hood portion 22 that covers each of the terminal accommodating portions 21 from the outside with a gap therebetween (FIGS. 1 to 5). The hood portion 22 shown here is formed in an elongated cylindrical shape. In the housing 20, an elongated cylindrical mating terminal accommodating portion 521 (FIG. 2) of a mating housing 520 is fitted into an elongated annular gap between the hood portion 22 and each of the terminal accommodating portions 21, and at the same time, each of the mating terminal connection portions 511 inside the mating terminal accommodating portion 521 is inserted into each of the terminal accommodating chambers 20a. Thus, in the housing 20, the hood portion 22 and each of the terminal accommodating portions 21 become fitting portions, and the fitting portions are fitted and connected to the mating terminal accommodating portions 521 as the mating fitting portions.

[0022] Here, the mating housing 520 is fixed to a metal housing 500a of the mating device 500, and is disposed in an oval through-hole 500b of a mating wall 500a1 of the housing 500a (FIG. 2). In the connector 1, the hood portion 22 of the housing 20 is inserted through an insertion opening 500b1 of the through-hole 500b. An oval cylindrical seal member 51 is attached to the oval outer peripheral surface of the through-hole 500b located on the insertion opening 500b1 side (FIGS. 1 to 5). The seal member 51 is a waterproof member that fills a part of an oval cylindrical gap between the oval outer peripheral surface of the housing 20 and the inner peripheral surface of the through-hole 500b of the housing 500a.

[0023] In the state where the hood portion 22 and the seal member 51 are accommodated in the through hole 500b (that is, in the state where the hood portion 22 and each of the terminal accommodating portions 21 as the mating portion are mated and connected to the mating terminal accommodating portion 521 as the mating portion (hereinafter referred to as the "mated and connected state")), the wall surface 500a1 on the insertion opening 500b1 side of the mating wall body 500a1 is 11 The housing 20 has a protrusion 23 that protrudes from the housing 20 (FIGS. 4 and 5). The protrusion 23 includes an electric wire receiving portion 24 of the housing 20.

[0024] The wire accommodating portion 24 is a cylindrical portion of the housing 20 that accommodates the electric wire We inward and draws it outward, and is provided for each electric wire We. A cylindrical seal member 52 is attached to the inside of the wire accommodating portion 24 to fill a part of the cylindrical gap between the inner peripheral surface of the wire accommodating portion 24 and the outer peripheral surface of the electric wire We (FIG. 4). The terminal fitting 10 attached to the end of the electric wire We is inserted from the electric wire outlet 24a of the wire accommodating portion 24 to the terminal accommodating chamber 20a. The connector 1 is provided with a rear holder 60 that is fitted into the gap between the electric wire outlet 24a of each wire accommodating portion 24 and the electric wire We (FIGS. 1, 2, 4, and 5).

[0025] The shield shell 30 covers the protruding portion 23 of the housing 20 from the outside, thereby suppressing the intrusion of external noise into the electric wires We inside each electric wire accommodating portion 24. Therefore, the shield shell 30 is formed of a metal material (for example, aluminum or an aluminum alloy).

[0026] The shield shell 30 has an oval cylindrical shield body 31 that covers the protruding portion 23 of the housing 20 from the outside (FIGS. 1 to 5). An oval ring-shaped seal member 53 is attached to the housing 20 on the oval outer peripheral surface of the protruding portion 23, which is closer to the hood portion 22 than the wire accommodating portions 24 (FIGS. 4 and 5). The seal member 53 is a waterproof member that fills a part of the oval cylindrical gap between the oval outer peripheral surface of the housing 20 and the inner peripheral surface of the shield body 31 of the shield shell 30.

[0027] The shield shell 30 is provided at one end of the shield body 31 in the axial direction, and is formed on a wall surface 500a1 on the side of the insertion opening 500b1 of the mating wall body 500a1 in a fitted and connected state. 11 1 to 5. The shield shell 30 protrudes from the flange portion 32 and contacts the wall surface 500a1 on the side of the insertion opening 500b1 of the mating wall body 500a1 in the mating connected state. 11 The fixing portion 33 has a through hole (hereinafter, referred to as a "bolt insertion hole") 33a that is arranged coaxially with the female screw portion 500c of the mating wall body 500a1 in the mating connection state (FIG. 4).

[0028] The connector 1 is provided with a metal bolt 70 that is inserted into the bolt insertion hole 33a and screwed into the female screw portion 500c to screw-fix the fixing portion 33 to the mating wall body 500a1 (FIGS. 1 to 5). The bolt 70 has a male screw portion 71 that is inserted into the bolt insertion hole 33a and screwed into the female screw portion 500c in a fitted connection state, and a head portion 72 that receives axial torque from a tool (not shown) when screwing (FIGS. 4 and 5). The connector 1 is provided with a snap ring 75 that holds the bolt 70 rotatably about the axis relative to the fixing portion 33 with the male screw portion 71 inserted into the bolt insertion hole 33a (FIGS. 1 and 3 to 5).

[0029] Here, in this connector 1, the head 72 of the bolt 70 protrudes to the outside, and depending on the installation location, there is a possibility that liquid such as water may adhere to the head 72. Therefore, this connector 1 is provided with a bolt cap 80 that covers the head 72 (FIGS. 1 to 8). This bolt cap 80 is molded from a flexible material such as synthetic rubber. For ease of explanation, in FIGS. 7 and 8, the bolt cap 80 is not shown in cross section.

[0030] The bolt cap 80 has a cap body 81 that covers the head 72 to hide the head 72, a retaining body 82 that is inserted into the through hole (hereinafter referred to as the "retaining hole") 33b of the fixing part 33 from the entrance 33b1 to be tightly fitted and retained in the retaining hole 33b, and a connecting body 83 that connects the cap body 81 and the retaining body 82 (Figures 1 to 8).

[0031] The cap body 81 is formed in a cylindrical shape with one end closed and the other end open, and the head 72 of the bolt 70 is inserted from the opening. This cap body 81 is formed in a cylindrical shape corresponding to the head 72. The cap body 81 shown here is formed in a cylindrical shape with one end closed to match the shape of the head 72 of a hexagonal bolt. The annular end face on the opening side of the cap body 81 shown here is brought into close contact with the annular seat 72a of the head 72, preventing liquid from entering between this end face and the seat 72a (FIGS. 4 and 5). is.

[0032] The holding body 82 and the connecting body 83 are formed in a bendable shaft shape that protrudes and extends from the outer circumferential surface of the cap body 81. The holding body 82 shown here has an insertion part 82a into which a tip 82a1 is inserted from an entrance 33b1 of the holding hole 33b and passed through the holding hole 33b (FIGS. 5 to 8). Here, the insertion part 82a and the connecting body 83 are formed as a cylindrical shaft.

[0033] The retaining body 82 is inserted into the cylindrical retaining hole 33b of the fixing part 33 in a tight contact state, so that it is retained by the inner peripheral surface of the retaining hole 33b and the gap between the retaining body 82 and the inner peripheral surface is blocked, thereby improving waterproofing. Therefore, the retaining body 82 is in close contact with the inner peripheral surface of the retaining hole 33b over the entire circumference. Therefore, the retaining body 82 has a lip portion 82b that is concentrically disposed on the outer peripheral surface of the insertion part 82a and is in close contact with the inner peripheral surface of the retaining hole 33b over the entire circumference (FIGS. 6 and 7). The lip portion 82b shown here is formed in an annular shape and is disposed at intervals along the axial direction of the insertion part 82a.

[0034] The retaining body 82 is held in the retaining hole 33b of the fixing part 33 by using the lip part 82b. The retaining body 82 uses the lip part 82b to close the annular gap between the outer circumferential surface of the insertion part 82a and the inner circumferential surface of the retaining hole 33b, thereby preventing the passage of liquid therebetween.

[0035] The bolt cap 80 inserts the tip 82a1 of the insertion portion 82a into the retaining hole 33b from the entrance 33b1. Here, the ease of inserting the insertion portion 82a into the retaining hole 33b is improved as follows. First, the entrance 33b1 of the retaining hole 33b is provided with a chamfered portion 33b2, which is chamfered around the entire periphery (FIGS. 5 and 7). Next, the tip 82a1 of the insertion portion 82a is formed into a pointed cone shape. That is, the entrance 33b1 of the retaining hole 33b shown here is formed into a truncated cone shape with a large diameter on the outside. And the tip 82a1 of the insertion portion 82a shown here is formed into a cone shape. This allows the bolt cap 80 to improve the ease of inserting the insertion portion 82a into the retaining hole 33b.

[0036] In addition, the bolt cap 80 inserts the tip 82a1 of the insertion portion 82a into the retaining hole 33b from the entrance 33b1, and the tip 82a1 protrudes from the exit 33b3 of the retaining hole 33b, thereby inserting the retaining body 82 into the retaining hole 33b (FIGS. 5, 7, and 8). 11 In order to prevent the wall surface 500a from contacting the 11 A recess 33c is provided between the wall surface 500a of the fixed portion 33 and the outlet 33b3 to accommodate the tip 82a1 (FIGS. 5, 7, and 8). 11 The outlet 33b3 of the retaining hole 33b is disposed in the recessed portion of the wall surface 500a when the retaining hole 33b is in the mated connection state. 11 The protruding end 82a1 is fitted and connected to the wall surface 500a at a position spaced from the wall surface 500a. 11 In this way, the bolt cap 80 is disposed at a position where it does not come into contact with the wall surface 500a. 11 Therefore, application of a load toward the inlet 33b1 side to the holder 82 can be prevented, so that the holding function of the holder 82 in the holding hole 33b can be maintained.

[0037] After the bolt 70 has been screwed in while in a fitted connection state, the cap body 81 of the bolt cap 80 is placed over the head 72 of the bolt 70 while bending the connector 83 .

[0038] As described above, the connector 1 of this embodiment can prevent the head 72 of the bolt 70 from being wetted by the bolt cap 80, thereby improving the durability of the head 72. The connector 1 can hold the retainer 82 on the inner circumferential surface of the retainer hole 33b by inserting the retainer 82 into the retainer hole 33b of the fixing part 33 in a tight contact state, and can block the gap between the inner circumferential surface and the retainer 82 to prevent a decrease in waterproofing. When the connector 1 inserts the retainer 82 into the retainer hole 33b, the chamfered portion 33b2 of the entrance 33b1 of the retainer hole 33b and the cone shape of the tip 82a1 of the insertion part 82a act as pick-up, improving the ease of inserting the retainer 82 into the retainer hole 33b. The connector 1 also covers the head 72 of the bolt 70 with the bolt cap 80, which contributes to improving the appearance. In addition, this connector 1 only requires that the cap body 81 be placed over the head 72 of the bolt 70, and when providing the bolt cap 80, there is no need to provide the bolt 70 with a special shape for the bolt cap 80, so a versatile standard bolt 70 can be used.

[0039] [Variations] The connector 2 of this modification is obtained by replacing the shield shell 30 and the bolt cap 80 of the connector 1 of the above-described embodiment with the shield shell 130 and the bolt cap 180 described below (FIGS. 9 to 14). For this reason, in the following, for parts and parts that are unchanged from the embodiment and parts and parts that can be regarded as equivalent to those of the embodiment, the reference numerals will be used as necessary, and the explanations here will be omitted, and the reference numerals will be omitted as necessary.

[0040] The shield shell 130 of this modification corresponds to the shield shell 30 of the above-mentioned embodiment in which the fixing portion 33 is replaced with the fixing portion 133 described below (FIGS. 9 to 11, 13, and 14). The fixing portion 133 of this modification has a bolt insertion hole 33a, a retaining hole 133b, and a recess 133c similar to the fixing portion 33 of the above-mentioned embodiment (FIGS. 11, 13, and 14). The retaining hole 133b has a chamfered portion 133b2 at an entrance 133b1 similar to the retaining hole 33b of the above-mentioned embodiment (FIGS. 11 and 13).

[0041] On the other hand, unlike the fixing portion 33 of the previously described embodiment, the fixing portion 133 of this modified example has a countersunk portion 133d with which the annular end portion 184a of the covering portion 184 described below in the bolt cap 180 comes into annular surface contact while reducing the gap (Figures 10, 11, 13 and 14).

[0042] Here, the bolt cap 180 of this modification has a cap body 181, a retaining body 182, and a connecting body 183 similar to those of the bolt cap 80 of the previously described embodiment (FIGS. 11 to 14). The retaining body 182 has an insertion portion 182a and a lip portion 182b similar to those of the retaining body 82 of the previously described embodiment (FIGS. 12 and 13).

[0043] On the other hand, the bolt cap 180 of this modification is different from the bolt cap 80 of the above-mentioned embodiment in that it has a covering portion 184 that is in close contact with the periphery of the inlet 133b1 in the outer wall 133e on the inlet 133b1 side of the fixing portion 133 and covers the inlet 133b1 (FIGS. 10 to 14). This covering portion 184 is provided to prevent liquid from entering the inlet 133b1, and is formed in a truncated cone shape that is coaxial with the insertion portion 182a and the connecting body 183. This covering portion 184 is disposed at the boundary between the holding body 182 and the connecting body 183. This covering portion 184 has a lower annular end portion 184a that is in close contact with the periphery of the inlet 133b1 in the outer wall 133e of the fixing portion 133, thereby preventing liquid from entering the inlet 133b1 from the periphery (FIGS. 11 and 14). Here, the peripheral portion is provided on the bottom surface of the countersunk portion 133d.

[0044] The countersunk portion 133d is a recess formed by countersunk processing in a circular shape on the outer wall 133e of the fixing portion 133 on the inlet 133b1 side, and the inlet 133b1 of the holding hole 133b is disposed on the bottom surface of the countersunk portion 133d. The surface roughness of the bottom surface of the countersunk portion 133d is smaller than the surface roughness of the wall surface of the outer wall 133e of the fixing portion 133. This allows the annular end 184a of the covering portion 184 to come into annular surface contact with the bottom surface of the countersunk portion 133d while suppressing a gap. Therefore, in this connector 2, the occurrence of a gap between the bottom surface of the countersunk portion 133d and the annular end 184a of the covering portion 184 is suppressed, and thus the waterproofing between them can be improved.

[0045] The bolt cap 180 of this modification is also different from the bolt cap 80 of the embodiment described above in the following respect. The retainer 182 of this modification has a locking portion 182c provided at the tip 182a1 of the insertion portion 182a and formed in a pointed umbrella shape (FIGS. 11 to 14). This locking portion 182c is locked to the wall surface of the outlet 133b3 side of the fixed portion 133 after passing through the outlet 133b3 of the retaining hole 133b. The locking portion 182c shown here is formed in a conical umbrella shape coaxial with the insertion portion 182a, and the annular end portion 182c1 on the bottom side is locked to the wall surface of the outlet 133b3 side of the fixed portion 133 and to the peripheral portion of the outlet 133b3 (FIGS. 11 and 14). The bolt cap 180 of this modification can improve the holding force to the fixed portion 133 by the locking portion 182c.

[0046] Here, the locking portion 182c has a pointed cone shape, similar to the tip 82a1 of the insertion portion 82a in the above-described embodiment. Therefore, in the bolt cap 180 of this modification, similar to the bolt cap 80 in the above-described embodiment, the chamfered portion 133b2 of the entrance 133b1 of the retaining hole 133b and the cone shape of the locking portion 182c act as a complement, improving the ease of inserting the insertion portion 182a into the retaining hole 133b.

[0047] As described above, the connector 2 of this modified example has the same effects as the connector 1 of the embodiment. Furthermore, the connector 2 of this modified example can ensure waterproofing greater than or equal to that of the connector 1 of the embodiment by the covering portion 184 of the bolt cap 180, and can ensure a holding force of the bolt cap 180 greater than or equal to that of the connector 1 of the embodiment by the locking portion 182c.
