Description

[Technical Field]

[0001] The present invention relates to a wire cover that is attached to the rear end of a connector housing and that regulates the direction in which wires are led out from the rear of the connector housing. [Background technology]

[0002] 5 and 6 show a connector with a wire cover 501 equipped with a conventional wire cover 521. FIG. This conventional wire cover 521 is attached to the rear end of the housing body 513 of the connector housing 511, and first bends the wire bundle 61 consisting of multiple wires 63 leading out from the rear of the housing body 513 to the side and then leads it in a predetermined direction.

[0003] The wire cover 521 has a pair of side walls 523, 523 and a curved ceiling wall 525 having a curved surface, thereby forming a bending direction guide wall with a U-shaped cross section that guides the wire bundle 61 drawn out from the rear of the housing main body 513 to bend sideways (towards the left in Figure 5).

[0004] A flapper portion 541 extending in a predetermined direction in which the wire bundle 61 is led out (diagonally upward to the left in FIG. 6) is integrally formed on an end portion 525a of the ceiling wall 525 in the wire bending direction (left direction in FIG. 5) of the wire cover 521. The flexure part 541 has a binder attachment part 549 at its tip. Then, the wire bundle 61 arranged along the inner surface of the flexure part 541 is fixed to the flexure part 541 by a binding band 51 inserted into a binding band insertion hole 549a of the binding band attachment part 549.

[0005] Therefore, it is possible to restrict the wire bundle 61, which is bent from the rear portion of the housing main body 513 toward the side, to a predetermined leading-out direction. However, in the above-described connector with wire cover 501, in order to change the leading-out direction of the wire bundle 61, it is necessary to replace the wire cover 521 with another wire cover having a different leading-out direction of the latch part 541, and it is necessary to prepare and manufacture a plurality of wire covers for each leading-out direction of the wire bundle 61.

[0006] In contrast to this, a connector with a wire cover that can change the lead-out direction of the wires with a single cover is known, for example, as disclosed in Patent Document 1. This connector with a wire cover includes a housing from which wires are drawn backward from the rear, and a wire cover attached to the rear of the housing and guiding the wires in a predetermined direction. The wire cover has a first cover attached to the rear of the housing, a second cover assembled to the first cover and changing the direction in which the wires are drawn out, and a displacement means for changing the direction in which the wires are drawn out by the second cover while the first cover remains attached to the rear of the housing. Therefore, according to this connector with a wire cover, the direction in which the wires are led out can be changed with one wire cover. [Prior art documents] [Patent documents]

A wire cover is attached to a rear end of a connector housing and regulates the direction in which wires are led out from the rear of the connector housing, a bending direction guide wall that bends the electric wires led out from the rear portion of the connector housing toward the side; a movable bell member rotatably provided on the bending direction guide wall, the extending direction of which is changed in accordance with the leading direction of the electric wire; a restricting mechanism that restricts the extending direction of the movable lever member; A wire cover comprising: [Effects of the Invention]

[0011] According to the present invention, it is possible to provide a compact wire cover that allows the direction in which wires are led out from a connector housing to be easily changed with a single wire cover.

[0012] The present invention has been briefly described above. The details of the present invention will become clearer by reading the following detailed description of the invention (hereinafter referred to as "embodiments") with reference to the accompanying drawings.

[Figure 6]FIG. 6 is a perspective view of a conventional connector with a wire cover. [Figure 7] FIG. 7 is a plan view showing a state in which the direction in which the wires are led out from the rear part of the connector housing is restricted by the conventional connector with a wire cover shown in FIG. DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view of a connector with a wire cover 1 including a wire cover 21 according to one embodiment of the present invention. Fig. 2 is an exploded perspective view of the connector with a wire cover 1 shown in Fig. 1. Fig. 3 is a plan view showing a state in which the direction in which the wires 63 are led out from the rear of the connector housing 11 is restricted by the connector with a wire cover 1 shown in Fig. 1.

[0015] As shown in FIG. 1, the connector with wire cover 1 equipped with the wire cover 21 according to this embodiment has a connector housing 11 that is fitted to and separated from a mating connector housing (not shown) via a lever, and the wire cover 21 that regulates the direction in which the wires 63 are led out from the rear (upper part in FIG. 1) of the connector housing 11.

[0016] 2, the connector housing 11 has a housing body 13 made of synthetic resin and a lever (not shown). The housing body 13 is formed in a rectangular parallelepiped (block-like) shape with terminal accommodating chambers 17, which accommodate connection terminals (not shown), arranged in parallel in multiple stages on the top, bottom, left, and right.

[0017] A plurality of electric wires 63 connected to the connection terminals accommodated in each terminal accommodating chamber 17 are led out from the rear opening of the terminal accommodating chamber 17, and then formed into an electric wire bundle 61 and led out from the rear of the housing main body 13 (see Figure 3). A support shaft 14 for rotatably supporting a lever is provided in a protruding manner on both side walls 13a, 13a of the housing body 13 along the longitudinal direction.

[0018] The wire cover 21 is a cover for protecting the wire bundle 61 led out from the rear of the housing body 13 from mechanical load, and is formed so that a surface facing the rear opening of the terminal accommodating chamber 17 and one end surface continuous with the facing surface are open. That is, the wire cover 21 configures a bending direction guide wall 27 having a U-shaped cross section with a pair of side walls 23, 23 that form the opening and a curved ceiling wall 25 having a curved surface.

[0019] The wire cover 21 is attached so as to be prevented from coming off by slidingly engaging with the protrusions 15 provided on the rear end portions of the outer surfaces of the side walls 23 of the housing body 13 along the longitudinal direction. The wire cover 21 is then assembled to the rear end portion of the housing body 13.

[0020] Furthermore, the wire cover 21 of this embodiment is provided with a movable lever member 41 that is rotatably mounted on the wire bending direction end (left end in Figure 2) 25a of the ceiling wall 25 in the bending direction guide wall 27, and whose extension direction is changed depending on the lead-out direction of the wire bundle 61, and a regulating mechanism 50 that regulates the extension direction of the movable lever member 41.

[0021] 3(a) and 3(b) are enlarged perspective views of the movable bellows member 41 shown in FIG. 2, viewed obliquely from above and below. As shown in (a) and (b) of the figures, the movable bellows member 41 is integrally formed with a bellows main body 42 having a substantially rectangular flat plate shape and a binding device attachment portion 49 having a quarter-circular cross section and provided at the tip of the bellows main body 42 in the extension direction.

[0022] A shaft 45 extending vertically from the upper surface of the rotor body 42 has a pair of locking projections 43, 43 formed on the top of a cylindrical base 44. The pair of locking projections 43, 43 are elastically displaceable radially inward by slits formed along the axial direction of the cylindrical base 44. An oblong cylindrical projection 47 is provided vertically on the upper surface of the base end of the bellows body 42 in the extending direction, rearward of the shaft portion 45.

[0023] The binder attachment portion 49 has a binder insertion hole 49a provided on the outer periphery and through which the binder (binder) 51 is inserted, and a restriction wall 49b extending in the circumferential direction of the outer periphery and restricting the binder 51, and is wound around the binder 51. The inner circumferential surface of the binder attachment portion 49 is formed as a wire attachment surface 48 that contacts along the side of the wire bundle 61 attached to the binder attachment portion 49.

[0024] FIG. 4 is an enlarged plan view of the main part showing the rotation range of the movable bell member 41. As shown in FIG. As shown in Figure 4, the regulating mechanism 50 is compactly configured and includes a shaft support hole 31 and multiple grooves 33 formed in the end 25a of the wire bending direction of the ceiling wall 25 of the wire cover 21, and a shaft 45 and protrusions 47 vertically attached to the upper surface of the wrench body 42.

[0025] The shaft support hole 31 is a circular hole that rotatably supports the cylindrical base 44 of the shaft 45. The peripheral edge of the shaft support hole 31 engages with a pair of locking projections 43, 43 of the shaft 45 inserted from below the ceiling wall 25, thereby preventing the movable bellows 41 from coming loose.

[0026] Multiple (five in this embodiment) grooves 33 are formed at equal intervals on the inner side edge of a sectorial opening 35 with the shaft support hole 31 as the arc center, and by engaging the protrusion 47 of the movable bell member 41 with any of them, the extension direction of the movable bell member 41 can be changed. That is, in the restriction mechanism 50 of this embodiment, five grooves 33 are provided, so that the extending direction of the movable fin member 41 can be changed in five stages within a rotation range of approximately 90 degrees.

[0027] FIG. 5 is a plan view showing a state in which the direction in which the wires 63 are led out from the rear part of the connector housing 11 is restricted by the connector with wire cover 1 shown in FIG. The movable lever member 41 is restricted in advance by the restricting mechanism 50 to a predetermined extending direction relative to the wire cover 21 .

[0028] 5, wire bundle 61 consisting of a plurality of wires 63 led out from the rear of connector housing 11 is bent laterally by bending direction guide wall 27, and then bound and attached to movable lever 41 by cable ties 51 attached to binder attachment portion 49 in a state where the wire bundle 61 is aligned with wire connection surface 48 of binder attachment portion 49. Therefore, wire bundle 61 bent laterally from the rear of housing main body 13 by wire cover 21 is restricted to a predetermined leading-out direction by movable lever 41.

[0029] As described above, according to the wire cover 21 of this embodiment, as shown in FIG. 5, by changing the groove portion 33 with which the protrusion 47 of the movable fin member 41 engages, the lead-out direction of the wire bundle 61 that is led out from the rear part of the housing main body 13 and bent laterally by the bending direction guide wall 27 can be easily changed with one wire cover 21.

[0030] Furthermore, the movable bellows member 41 can be made smaller than the bending direction guide wall 27, which is formed with a U-shaped cross section by a pair of side walls 23, 23 and the ceiling wall 25, so the entire wire cover 21 can be made compact.

[0031] Furthermore, according to the wire cover 21 of this embodiment, the regulating mechanism 50 is compactly configured to have an axle support hole 31 and multiple grooves 33 formed in the end 25a of the wire bending direction of the ceiling wall 25 of the wire cover 21, and an axle 45 and protrusion 47 vertically attached to the upper surface of the wrench body 42.

[0032] Furthermore, according to the electric wire cover 21 of this embodiment, the tip of the movable lever member 41 in the extending direction is provided with a binder attachment portion 49 for attaching a binding band 51 for binding the electric wire bundle 61 (electric wires 63). Therefore, the bundle of electric wires 61 (electric wires 63) can be easily attached to the movable lever member 41 by the binding band 51, improving workability.

[0033] Furthermore, according to the wire cover 21 of this embodiment, the inner surface of the binder attachment portion 49, which is formed in a quarter-circular cross section, is made into a wire attachment surface 48 that contacts along the side of the wire bundle 61 (wires 63) attached to the binder attachment portion 49. Therefore, when attaching the wire bundle 61 (wires 63) to the movable lever member 41, the wire bundle 61 (wires 63) can be fixed to the binder attachment portion 49 stably and reliably.

[0034] Therefore, it is possible to provide a compact wire cover 21 that allows the direction in which the wires 63 are led out from the connector housing 11 to be easily changed with a single wire cover 21.

[0035] The present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. Furthermore, the material, shape, size, number, location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as they can achieve the present invention.

[0036] For example, in the above embodiment, the shaft 45 and protrusion 47 that constitute the regulating mechanism 50 are formed on the movable bell member 41, and the shaft support hole 31 that is rotatably supported on the shaft 45 and the multiple grooves into which the protrusions are engaged are formed on the bending direction guide wall 27, but it is also possible to form multiple grooves that reach the shaft support hole on the movable bell member, and form the shaft and protrusions on the bending direction guide wall.

[0037] Furthermore, according to the above embodiment, the connector with the wire cover to which the wire cover is attached is a lever-type connector, but it goes without saying that the wire cover may also be attached to the rear end of a type of connector that is not a lever-type connector.
