Description

[Technical field]

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

[0002] Conventionally, a connector has been proposed that has a plurality of first connector housings and a second connector housing that accommodates the plurality of first connector housings arranged in one direction (Patent Document 1). The second connector housing has accommodation chambers for the plurality of first connector housings that are partitioned by walls. Since the inside of the second connector housing is thus partitioned by walls, there has been a problem in that the width of the connector in one direction is wide.

[0003] Also, a connector in which multiple connector housings are arranged in one direction and screwed to a plate-shaped connecting part has been considered. However, since the connector housings need to be stacked one by one on the connecting part and screwed, it is necessary to leave a gap between the connector housings, which causes a problem that the width of the connector in one direction is wide.

[Brief description of the drawings]

[0009] [Figure 1] FIG. 1 is a rear view showing one embodiment of a connector of the present invention. [Diagram 2] FIG. 2 is a front view of the connector shown in FIG. [Diagram 3] 3 is a right side view of the electric wires, the terminals, and the housing portion shown in FIG. [Figure 4] FIG. 4 is an explanatory diagram for explaining an assembly procedure of the connector shown in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0011] For the sake of convenience, the following definitions are used for "front", "rear", "left", "right", "upper" and "lower" as shown in Figs. 1 to 4. The "front-rear direction", "left-right direction" and "up-down direction" are mutually orthogonal. The left-right direction corresponds to "one direction" in the present invention.

[0012] The connector 1 is, for example, a connector constituting part of a wire harness arranged in a vehicle or the like, and is fixed to the vehicle body, the vehicle motor, etc. As shown in Figures 1 and 2, the connector 1 includes a plurality of terminals 3 (see Figure 2) attached to ends of electric wires 2, a plurality of housing parts 4 (see Figure 1) that individually accommodate the plurality of terminals 3, and a connection part 5 in which the plurality of housing parts 4 are fixed in a line in the left-right direction and which collectively holds the plurality of terminals 3 so that they can be connected to a mating connector.

[0013] In this embodiment, the electric wire 2 is a shielded electric wire shielded by a braid (not shown). In this embodiment, six electric wires 2 are provided.

[0014] As shown in Fig. 2, the connector 1 has terminals 3 in the same number as the electric wires 2. In this embodiment, the connector 1 has six terminals 3. The terminals 3 are made of a conductive material such as metal. The terminals 3 have an electric wire connection portion (not shown) to which the electric wires 2 are attached and which connects the terminals 3 and the electric wires 2, a terminal connection portion 31 which is connected to a mating terminal of a mating connector, and a shield portion 32 which is connected to the braid of the electric wires 2. The shield portion 32 surrounds the outer periphery of the terminal connection portion 31 in the circumferential direction.

[0015] As shown in Fig. 1, the connector 1 has housing portions 4 in the same number as the terminals 3. In this embodiment, the connector 1 has six housing portions 4. The housing portions 4 are made of an insulating material such as synthetic resin. The housing portions 4 are provided separately from the connection portions 5, and each house the electric wire connection portions of the multiple terminals 3.

[0016] 3, the housing 4 has a box-shaped main body 41 that houses the electric wire connection portion of the terminal 3, and an attachment portion 42 that protrudes upward from the main body 41 and is screwed onto a connection portion 5 described below. The terminal connection portion 31 and the shield portion 32 of the terminal 3 are disposed protruding outside the main body 41 from an opening provided on the upper side of the front side of the main body 41. The electric wire 2 is drawn downward from an opening provided on the lower surface of the main body 41.

[0017] The mounting portion 42 is thinner in the front-rear direction than the main body portion 41. The front side surfaces of the main body portion 41 and the mounting portion 42 are flush with each other. As shown in Fig. 4, the mounting portion 42 is provided with a through hole 42A penetrating in the front-rear direction. A metal collar 43 having a screw hole 43A penetrating in the front-rear direction is press-fitted into the through hole 42A. A thread groove that screws into the screw 10 is provided on the inner side surface of the screw hole 43A.

[0018] In this embodiment, as shown in Fig. 1, the width of the mounting portion 42 in the left-right direction is set to be the same as the width of the main body portion 41 in the left-right direction. As shown in Fig. 4, the mounting portion 42 has a convex portion 42B (first fitting portion) provided on the left side surface and a concave portion 42C (second fitting portion) provided on the right side surface. In adjacent housing portions 4, 4, the convex portion 42B of the right housing portion 4 is press-fitted (fitted) into the concave portion 42C of the left housing portion 4. This allows multiple housing portions 4 to be aligned and fixed in the left-right direction.

[0019] The connection part 5 is made of a conductive material. When the connection part 5 is fixed to a vehicle body or a motor of a vehicle, it is grounded. As shown in FIG. 2, the connection part 5 has a flat-plate-shaped holding part 51 that holds the terminal connection part 31 and the shield part 32 of the terminal 3, and a positioning part 52 that protrudes forward from the holding part 51. The holding part 51 is provided with an insertion hole (not shown) through which the terminal connection part 31 and the shield part 32 of the terminal 3 pass, and a screw hole (not shown) for fixing the housing part 4. A plurality of insertion holes are provided in a line in the left-right direction. By passing the shield part 32 through this insertion hole, the shield part 32 and the connection part 5 are electrically connected, and the shield part 32 is grounded. A plurality of screw holes are also provided in a line in the left-right direction. A screw groove that screws into the screw 10 is provided on the inner surface of the screw hole provided in the holding part 51.

[0020] The positioning portion 52 is provided integrally with the holding portion 51 on the front surface of the holding portion 51, and is a portion that fits with a mating connector. The positioning portion 52 is provided so as to surround all of the through holes aligned in the left-right direction.

[0021] Next, a procedure for attaching the housing part 4 accommodating the terminals 3 to the connection part 5 will be described. First, the concave parts 42C are press-fitted into the convex parts 42B of the adjacent housing parts 4 to align and fix the multiple housing parts 4 in the left-right direction. At this time, all the housing parts 4 to be attached to the connection part 5 are aligned and fixed in the left-right direction. According to this embodiment, six housing parts 4 are aligned and fixed in the left-right direction.

[0022] At this time, the left and right side surfaces of the main body part 41 and the mounting part 42 come into contact with each other in adjacent housing parts 4. To explain in detail, in adjacent housing parts 4, the right side surface of the main body part 41 and the mounting part 42 of the left housing part 4 comes into contact with the left side surface of the main body part 41 and the mounting part 42 of the right housing part 4.

[0023] Next, the six housing parts 4 aligned and fixed in the left-right direction are collectively attached to the connection part 5. Specifically, the screw holes 43A provided in each of the six housing parts 4 are aligned with six screw holes (not shown) provided in the connection part 5. Thereafter, the screws 10 are screwed into the screw holes 43A provided in the housing parts 4 and the screw holes provided in the connection part 5, and the housing parts 4 are collectively attached to the connection part 5.

[0024] According to the embodiment described above, it is no longer necessary to screw the housing parts 4 one by one. Therefore, it is no longer necessary to provide a space between the housing parts 4 required for the screwing operation, so that the width of the connector 1 in the left-right direction can be reduced, thereby making the connector 1 more compact.

[0025] According to the embodiment described above, when the convex portion 42B and the concave portion 42C of adjacent housing portions 4 are fitted together, the left and right side surfaces of the main body portion 41 of the adjacent housing portions 4 come into contact with each other. This allows the multiple housing portions 4 to be more firmly aligned and fixed in the left and right direction, and also allows the width of the connector 1 in the left and right direction to be reduced, thereby making the connector 1 more compact.

[0026] According to the embodiment described above, the left-right widths of the main body 41 and the attachment portions 42 in the housing portion 4 are set to be the same. This allows the left-right side surfaces of the attachment portions 42 in adjacent housing portions 4, 4 to come into contact with each other, making it possible to more firmly align and fix the multiple housing portions 4 in the left-right direction.

[0027] According to the above-described embodiment, the connector 1 comprises a plurality of terminals 3, a plurality of housing portions 4 which individually accommodate the plurality of terminals 3, and a connection portion 5 to which the plurality of housing portions 4 are fixed in a line in the left-right direction, and the housing portions 4 are screwed in place by the connection portions 5.

[0028] According to this configuration, the connection portion 5 can hold the multiple terminals 3 and connect them together to the mating connector, so that the connector can be efficiently connected to the mating connector. In addition, the multiple terminals 3 are individually housed in the multiple housing portions 4 that are provided separately from the connection portion 5 and screwed to the connection portion 5. Therefore, even if the requirement for the number of electric wires 2 is different, it can be accommodated by increasing or decreasing the number of housing portions 4 that are fixed side by side while keeping the structure of the connection portion 5 the same. This improves the versatility of the connector 1 and reduces the manufacturing cost of the connector 1.

[0029] The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, etc. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary as long as the present invention can be achieved, and are not limited.

[0030] In the above-described embodiment, the multiple terminals 3 are collectively connected to the mating connector, but the present invention is not limited to this. The multiple terminals 3 may be connected to the mating connectors one by one.
