Summary of Invention
Technical Problem
In the related connector with the wire cover as describe above, because the mating parts are coupled by closing members (the connecting adapter and the direction regulating protector) corresponding to the cover which are half-cut-pipe shaped, there is a problem that the wire cover cannot be easily assembled, namely, the assembling property is inferior. Since the connecting adapter is pipe-shaped, it is difficult to bend the wires drawn out backwards from the rear of the connector body laterally just after the connector body. Therefore, there is a problem that it is hard to apply the connecting adapter and the direction regulating protector to a connector with a lever for which a rotation space behind the connector body is necessary. It is therefore one advantageous aspect of the present invention to provide a connector with a wire cover which makes it easy to assemble to an connector body and which is applicable to, for example, a connector with a lever for which a rotation space of the lever behind the connector body is necessary.
Solution to Problem
According to one advantage of the invention, there is provided a connector including a wire cover, comprising:
a connector body, wires being drawn out backwards from a rear of the connector body;
a wire cover, attached to the rear of the connector body, configured to arrange the wires drawn out backwards from the rear of the connector body so as to be bent once laterally and guided to a predetermined direction, and divided into a first cover and a second cover;
a bend guiding wall, provided in the first cover, having a U-shaped section, and configured to laterally bend the wires drawn out backwards from the rear of the connector body;
a sliding-type first locking mechanism, provided between one end of the first cover and the rear of the connector body, and configured to slide the first cover in a specific direction to the rear of the connector body and to lock the first cover and the connector body so as to releasably couple the rear of the connector body with the first cover by sliding;
a extraction guiding wall, provided in the second cover, having a U-shaped section, and configured to guide and extract the wires, which are laterally bent by the bend guiding wall, to a predetermined direction; and
a sliding-type second locking mechanism, provided between one end of the second cover and the other end of the first cover, and configured to slide the second cover in a specific direction to the other end of the first cover and to lock the second cover and the first cover so as to releasably couple the one end of the second cover with the other end of the first cover.
The connector with the wire cover may be configured such that: the first locking mechanism slides the first cover towards the lateral direction in which the wires are bent so as to lock the first cover to the rear of the connector body, and the second locking mechanism slides the second cover forwards so as to lock the second cover to the other end of the first cover. The connector with the wire cover may be configured such that: a lever for fitting a mating connector is pivotably attached to the connector body, and the first cover is provided in a non-interference space at the inner side of pivoting traces of the lever. The second cover may be selected from a plurality of kinds of second covers which make the extraction direction of the wires different and is coupled to the first cover.
Advantageous Effects of Invention According to the connector with the wire cover of the present invention, the wires drawn out backwards from the rear of the connector body can be led to be bent laterally immediately by the first cover one end of which is attached to the rear of the connector body. Therefore, for example, even when the space behind the connector body is limited since there is an obstacle near the rear of the connector body, the wires drawn out from the connector body can be dealt with no trouble. Because it is not necessary to prolong the wires behind the connector body, the first cover and the like are applicable to a connector with a lever. That is, in the case of the connector with the lever, when the connector body is fitted with a mating connector, for example, although it is necessary to pivot the lever towards the rear of the connector body, because the wires can be led laterally without becoming a trouble for the pivoting of the lever, the first cover and the like are applicable to the connector with the lever. The wires, which are led by the first cover to be bent laterally, can be extracted by being guided towards a predetermined direction by the second cover which is attached to the other end of the first cover. In this case, since the first cover is between the wires and the second cover at the preceding part of the second cover which decides the final extraction direction of the wires, by selecting a second cover suitable for a specific disposition condition from a plurality of kinds of second covers which make extraction directions different, it becomes possible to attach freely. Therefore, by merely preparing one kind of the first cover in accordance with the connector body, the first cover can be commonly used for the plurality of kinds of second covers, and versatility of the connector is improved. Further, because the first cover and the second cover do not have a half-cut structure, but are constructed to have the bend guiding wall and the extraction guiding wall of a U-shaped section, and the first cover and the second cover are slid in specific directions to be locked, the assembling operation is easily performed.
According to the connector with the wire cover of the invention, because the sliding/locking direction of the first cover is assumed as a lateral direction and the sliding/locking direction of the second cover is assumed as a forwards direction, the wires are prevented from being caught and the two covers can be attached sequentially in a reasonable way.
According to the connector with the wire cover of the invention, the wire cover can be disposed without interfering with the operation of the lever.
According to the connector with the wire cover of the invention, by selecting the second cover, the final extraction direction of the wires can be changed freely. According to the present invention, even when the space behind the connector body is limited, the wires drawn out from the connector body can be dealt with no trouble. Because it is not necessary to prolong the wires behind the connector body, the first cover and the like are applicable to a connector with a lever. Since the first cover is between the wires and the second cover at the preceding part of the second cover which decides the final extraction direction of the wires, by selecting a second cover suitable for a specific disposition condition from a plurality of kinds of second covers which make extraction directions different, it becomes possible to attach freely. Therefore, by merely preparing one kind of the first cover in accordance with the connector body, the first cover can be commonly used for the plurality of kinds of second covers, and versatility of the connector is improved.

Description of Embodiments
Below, an embodiment of the invention is described with reference to the figures.
In the following description, the side where a connector with an wire cover of the embodiment is fitted to a mating connector is assumed as a front side, the side opposite to the front side is assumed as a rear side, and the direction that a large number of terminals (not shown in the figures) are aligned in the connector is assumed as a right-to-left or left-to-right direction.
As shown in Fig. 1 , the connector with a wire cover of the embodiment includes a connector body 10, a wire cover 30 and a lever 20. Wires W are drawn out backwards from the rear of the connector body lO.The wire cover 30 is attached to the rear of the connector body 0 and extracts the wires W, which are drawn out backwards from the rear of the connector body 10, to a predetermined direction after the wires W are bent once towards a side (the left side opposite to the side where the lever 20 to be described below is attached). The lever 20 is attached to a position at the right side of the connector body 10 to be pivotable in an arrow X direction, and is pivoted backwards from the right side of the connector body 0 when the connector is fitted with a mating connector. As shown in Figs. 1 to 3, the wire cover 30 is divided into two parts, namely, a first cover 40 and a second cover 50 beside the connector body sequentially along a leading direction of the wires W drawn from the rear of the connector body 10. The first cover 40 has a bend guiding wall 41 of a U-shaped section to lead the wires W, which are drawn out backwards from the rear of the connector body 10, to bend laterally. The first cover 40 is constructed to be received in a non-interference space at the inner side of pivoting traces of the lever 20 to make it possible to perform an operation of fitting the connector with the mating connector. At one end (front end) of the first cover 40 and the rear of the connector body 10, sliding-type first locking mechanisms 14 and 44 are provided which releasably couple the rear of the connector body 10 with the first cover 40 by sliding the first cover 40 in a specific direction to the rear of the connector body 10 to lock the first cover 40 and the connector body 10. The sliding direction when the first cover 40 is locked in this case is the direction that the wires W are bent laterally, that is, a direction from right to left. The second cover 50 has a extraction guiding wall 51 of a U-shaped section to extract the wires W, which are led by the bend guiding wall 41 of the first cover 40 to be bent laterally, by guiding the wires W to a predetermined direction. One end 53 of the second cover 50 overlaps the other end (left end) 43 of the first cover 40. At the one end 53 of the second cover 50 and the other end 43 of the first cover 40, sliding-type second locking mechanisms 45 and 55 are provided which releasably couple the one end 53 of the second cover 50 with the other end 43 of the first cover 40 by sliding the second cover 50 in a specific direction to the other end 43 of the first cover 40 to lock the second cover 50 and the first cover 40. The sliding direction that the second cover 50 is locked in this case is a direction from rear to front.
When the wire cover 30 is to be assembled to the connector body 10, as shown in Fig. 3, first, the first cover 40 is slid from the right side to the left side as shown with an arrow A. Then, as shown in Fig. 4, the first cover 40 is coupled to the connector body 10 when the first locking mechanisms 14 and 44 are engaged with each other. Then, the one end 53 of the second cover 50 is slid towards the other end 43 of the first cover 40 from the rear side to the front side as shown with an arrow B. Then, as shown in Fig. 5, the second cover 50 is coupled to the first cover 40 when the second locking mechanisms 45 and 55 are engaged with each other. Thereby, the wire cover 30 has been attached. Then, the lever 20 is attached to the connector body 0, and thereby the connector is completed.
As described above, with the connector with the wire cover of the present embodiment, the wires W drawn out backwards from the rear of the connector body 10 can be led to be bent laterally immediately by the first cover 40 one end of which is attached to the rear of the connector body 10. Therefore, for example, even when the space behind the connector body 10 is limited since there is an obstacle near the rear of the connector body 0, the wires W drawn out from the connector body 10 can be dealt with no trouble.
Because it is not necessary to prolong the wires W behind the connector body 10, the first cover 40 and the like are applicable to a connector with a lever like that of the present embodiment. That is, in the case of the connector with the lever, when the connector body 10 is fitted with a mating connector, for example, although it is necessary to pivot the lever 20 towards the rear of the connector body 10, because the wires W can be led laterally without becoming a trouble for the pivoting of the lever 20, the first cover 40 and the like are applicable to the connector with the lever. In the embodiment, because the first cover 40 and the second cover 50 do not have a half-cut structure, but are constructed to have the bend guiding wall 41 and the extraction guiding wall 51 of a U-shaped section, and the first cover 40 and the second cover 50 are slid in specific directions to be locked, the assembling operation is easily performed. In particular, because the sliding/locking direction of the first cover 40 is assumed as a lateral direction and the sliding/locking direction of the second cover 50 is assumed as a forwards direction, the wires W are prevented from being caught and the two covers 40 and 50 can be attached sequentially in a reasonable way.
The wires W, which are led by the first cover 40 to be bent laterally, can be extracted by being guided towards a predetermined direction by the second cover 50 which is attached to the other end 43 of the first cover 40. In this case, since the first cover 40 is between the wires W and the second cover 50 at the preceding part of the second cover 50 which fixes the final extraction direction of the wires W, by selecting a second cover 50 suitable for a specific disposition condition from a plurality of kinds of second covers 50 which make extraction directions different, it becomes possible to attach freely. Therefore, by merely preparing one kind of the first cover 40 in accordance with the connector body 10, the first cover 40 can be commonly used for the plurality of kinds of second covers 50, and versatility of the connector is improved.
For example, with the second cover 50 of the above embodiment, the extraction direction of the wires W is set from a lateral direction to a slightly forwards direction, but it is also possible to extract the wires W to a direction perpendicular to the bending direction due to the first cover 40 with second covers 50A or 50B of Figs. 6A and 6B. In this case, only the directions of extraction guiding walls 51 A and 51 B have to be changed. Thus, by selecting the second cover, the final extraction direction of the wires W can be changed freely.
Fig. 7 shows that, as a comparative example to the embodiments, a wire cover 130 of a shape that integrates a part corresponding to a second cover 150 with a part corresponding to a first cover 140 is slid laterally to be attached to the connector body 0. When the wire cover 130 of the integrated structure is used in this way, the sliding/locking direction of locking mechanisms 14 and 114 at the rear of the connector body 10 and the end of the wire cover 130 is an arrow C direction so that the wire cover 130 can be easily attached to the connector body 10. However, it is only possible to make the wire cover 130 to slide in a specific direction depending on the direction of the extraction guiding wall 151 of the wires W, and it is not possible to lock.
Thus, as shown in Figs. 8 to 10, first, while a position where the wire cover 130 can be attached to the connector body 10 is searched (while parts surrounded by F are aligned), the wire cover 130 is attached forwards to the connector body 10. Next, from the position shown in Fig. 10, the wire cover 130 is slid laterally (from right to left) to the connector body 10 to make the wire cover 130 to be coupled to the connector body 10. In the case of the wire cover 130 of the integrated structure, it is very likely that the assembly becomes troublesome due to the variation of the extraction direction of the wires, but by dividing the wire cover 30 into the first cover 40 and the second cover 50 like those of the present embodiment, the trouble in the assembly can be reduced.
The present invention is not restricted to the above-described embodiments, and suitable modifications, improvements and the like can be made. Moreover, the materials, shapes, dimensions, numbers, installation places, and the like of the components in the above embodiments are arbitrarily set as far as the invention can be attained, and not particularly restricted.
The present application is based on Japanese Patent Application No. 2012-019877 filed on February 1 , 2012, the contents of which are incorporated herein by way of reference.
