CONNECTOR WITH SHIELD SHELL FOR CABLE Technical Field
A vehicle as a moving object includes a variety of electronic devices.
For example, a hybrid car or an electronic car includes the electronic devices such as a three-phase alternate current motor or an inverter to convert a direct-current power from a battery to an alternating-current power and supply it to the motor. In order to connect the motor to the inverter, for example, a connector is used which is connected to the motor through an electrical wire (for example, see Patent Literature l). The connector is configured such that a connection terminal of power supply side is fastened and connected using bolts to a bus bar which is a terminal stand provided in a casing. In addition, a shield wire is configured such that an end part thereof is peeled and the connection terminal is connected to a core wire, and a braid is engaged with a shell member provided at a holding tube through the shell member so as to be grounded.

In the connector 81, the shield shell 89 which enhances the
electromagnetic shield effect with respect to each of the cables 86 is not covered by the service cover 91. Thus, the electromagnetic shield is accomplished with respect to each of cables 86 using only the shield shell 89.
In addition, the connection areas between the terminal stand and the connection terminal 84 are located at the back of the accommodation space S of the connection part 85. In addition, the cable introduction part 87 extends above the connector main body 88 along the same direction as the fastening direction by the fastening bolts 93 of the connection terminal 84 and the terminal stand.
In order to achieve the object described above, a connector according to an aspect of the present invention is characterized by any one of (l) to (3) described below.
(l) A connector, including:
an attachment part that includes a terminal stand; a connector main body that includes a connection terminal connected to a cable, the connection terminal being fastened and fixed to the terminal stand in a state in which the connector main body is mounted to the attachment part!
a cable shield shell that covers an introduction part for the cable in the connector main body,' and
(2) The connector according to the configuration of (l), wherein the connector main body is configured such that the introduction part for the cable is inclined to a direction separate away from a fastening direction of the connection terminal to the terminal stand.
(3) The connector according to the configuration of (l) or (2), wherein the connector main body is molded in a state where the introduction part for the cable is embedded at a part of the connector main body.
In the connector having the configuration of (l) described above, in the connector main body which the connection part shield shell covers, each of the cables is covered by the cable shield shell and is also covered by the connection part shield shell. As a result, if sufficient electromagnetic shield effect may be anticipated with respect to each of the cables due to the connection part shield shell, even if the electromagnetic shield effect due to the cable shield shell is little, the cable shield shell can be made thinner and smaller since the influence of the electromagnetic shield effect with respect to each of the cables is little. In the connector having the configuration of (2) described above, since the introduction part of the cables is inclined to a direction separate away from the fastening direction of the connection terminal to the terminal stand, when the connector main body is fitted from above in the attachment part, the attachment part as the insertion opening, into which the connector main body is inserted, is not blocked by the cable introduction part and the cable shield shell. The attachment part as the insertion opening is sufficiently visible so that fitting of the connector main body into the attachment part is easily performed and the insertion of the connector main body into the attachment part can be prevented from being incomplete beforehand. Accordingly, the connection work can be greatly improved, the connection trouble or the like do not occur at the connection locations between the terminal stand and the connection terminal and the connection reliability can be increased.
In the connector having the configuration of (3) described above, since the cable connected to the connection terminal is embedded, for example, by insert molding, when the connector main body is attached to the terminal stand, the attachment work of the connection terminal to the connector main body is not required. Thus, the load of the attachment work of the connector main body to the terminal stand can be alleviated. In addition, the cable connected to the connection terminal is embedded in the connector and thereby the introduction part for the cable can be easily maintained in the inclined state. Advantageous Effects of Invention According to the aspect of the present invention, a connector can be provided which can increase the electromagnetic shield effect with respect to the shield electric wire and can achieve a thinner and smaller shape of the shield electric wire.
Hereinabove, the present invention is described briefly.
Furthermore, details of the present invention will be further clarified by reading the embodiments of the present invention described below with reference to accompanying drawings.
Fig. 1 is a perspective view of a connector according to an
Fig. 6 is a cross -sectional view taken along arrows VI- VI in Fig. 5 illustrating the integrated-type shield shell.
Description of Embodiments Hereinafter, an exemplary embodiment of the present invention is described with reference to drawings.
When the connection part shield shell 14 covers the attachment part
12 and the connector main body 13, the bolt insertion holes 58 are made to communicate with the screw holes 20 formed at the panel 11. In addition, at a portion where the fixing piece 43 of the cable shield shell 33 is arranged, the bolt insertion holes 58 are communicated with the hole sections 42 of the fixing piece 43 communicated with the screw holes 20 of the panel 11. In addition, in a case where the connection part shield shell 14 covers the attachment part 12 and the connector main body 13, the connection part shield shell 14 covers the fastening areas between the connection terminal 35 and the terminal stand 22 in order to accommodate the cable shield shell 33 inside thereof in a state where the service cover 51 is held between the connection part shield shell 14 and the connector main body 13. Thus, in the connector main body 13 on which the connection part shield shell 14 covers, each of the cables 38 is covered by the cable shield shell 33 and also covered by the connection part shield shell 14. As a result, the
electromagnetic shield effect with respect to each of the cables 38 can be increased. Furthermore, if sufficient electromagnetic shield effect is expected with respect to each of the cables 38 by the connection part shield shell 14, since the influence of the electromagnetic shield effect to each of the cables 38 is little even if the electromagnetic shield effect due to the cable shield shell 33 is little, the cable shield shell 33 can be made thinner and smaller.
In addition, in the connector according to the embodiment described above, since above the connector main body 13 attached to the attachment part 12 is opened, checking and visibility in the fastening areas of the connection terminal 35 to the terminal stand 22 can be largely improved. Accordingly, when the connection terminal 35 of the terminal plate section 31 is fastened and connected to the terminal stand 22 of the attachment part 12 by the fastening nuts 40, the connection work can be easily performed while the locations of the connection work can be checked visibly.
Accordingly, the connection work can be largely improved, the connection failure or the like does not occur at the connection locations between the terminal stand 22 and the connection terminal 35, and the connection reliability can be increased.
Figs. 5 and 6 illustrate an inte rated -type shield shell where the connection part shield shell 14 and the cable shield shell 33 are integrally formed in the connector according to the present embodiment. As shown in Fig. 5, an integrated-type shield shell 71 has a cable insertion part 72, into which the cables 38 are inserted, and a window area 73 formed to connect the terminal stand 22 and the connection terminal 35.
In addition, the cable insertion part 72 is also inclined to be matched with the cable introduction part 32 of the connector main body 13.
Accordingly, as shown in Fig. 6, an introduction direction B of the cable 38 with respect to a fastening direction A between the terminal stand 22 and the fastening nuts 40 is inclined. Thus, in order to perform press process of the integrated-type shield shell 71, the press work should be performed from two directions of a C direction and a D direction so that costs may increase due to the complexity of the manufacturing process.
In contrast, according to the present embodiment, when the terminal plate section 31 is fitted from above in the outer wall section 24 of the attachment part 12, the outer wall section 24 of the attachment part 12 as the insertion opening, which inserts the connector main body 13, is not blocked by the cable introduction part 32 and the cable shield shell 33. The outer wall section 24 of the attachment part 12 as the insertion opening is sufficiently visible so that the fitting of the terminal plate section 31 into the outer wall section 24 can be easily performed and the insertion of the connector main body 13 into the outer wall section 24 can be prevented from being incomplete beforehand. Accordingly, the fastening nuts 40 can be prevented from fastening to the fastening bolts 21 in a state where the insertion of the fastening bolts 21 into the connection holes 34 is incomplete. In addition, according to the present embodiment, since the connection part shield shell 14 covering the fastening areas between the connection terminal 35 and the terminal stand 22, and the cable shield shell 33 covering the cable introduction part 32 in the connector main body 13 are provided, the fastening work can be easily performed in a state where the fastening areas of the connection terminal 35 are exposed even though the cable shield shell 33 is attached, compared to using the integrated -type shield shell 71 where the cable insertion part 72 covering the cable insertion part 32 and the portion covering the fastening areas of the connection terminal 35 are integrated. In addition, it is possible to achieve simplification of the manufacturing process by simplifying the shape, and thereby achieving to be smaller and low cost.
The present application is based upon and claims the benefit of Japanese patent application No. 2011-161083 filed on July 22, 2011, the contents of which are incorporated by reference in its entirety. Industrial Applicability
