The connector of the present disclosure includes:
a first part having a pair of inner wall surfaces arranged to face each other;
a second component having a pair of outer wall surfaces arranged back to back and assembled to the first component with the pair of outer wall surfaces facing the pair of inner wall surfaces;
Equipped with
The pair of said inner wall surfaces and the pair of said outer wall surfaces constitute two sets of opposing wall surfaces, each of which is a combination of one said inner wall surface and one said outer wall surface facing each other,
Only one of the two sets of opposing wall surfaces is provided with thread ribs that are crushed and deformed when the first component and the second component are assembled.

According to the present disclosure, the positional relationship between the first component and the second component that are assembled to each other can be made constant.

According to the configuration of the present disclosure, when the first component and the second component are assembled, the inner wall surface and the outer wall surface are in direct contact with each other on the opposing wall surfaces on which the thread ribs are not arranged. The positional relationship between the two parts can be made constant.

(2) In (1), the first component has two pairs of the inner wall surfaces whose opposing directions are orthogonal, and the second component has two pairs of the outer wall surfaces whose opposing directions are orthogonal; It is preferable that the thread ribs are arranged only on two sets of the opposing wall surfaces that are perpendicular to each other among the four sets of the opposing wall surfaces. According to this configuration, the positional relationship between both components can be kept constant in two-dimensional directions orthogonal to each other.

(3) In (1) or (2), the first part and the second part are assembled in parallel to the length direction of the thread rib, and the first part is attached to a plurality of the threads. It is preferable that the thread ribs have ribs, and the positions of the front ends of the plurality of thread ribs in the assembly direction are different from each other.

The groove portion 94 brings the actuated portion 83 and the projection portion 51 into sliding contact, so that the female housing 50 and the moving plate 80 move together within the hood portion 21 of the male housing 20 . When the lever 90 moves to the rotation completion position (see FIG. 12), the male housing 20 and the female housing 50 are fitted together, and the male terminal fitting 30 and the female terminal fitting 60 are connected.

2. Structure of Thread Ribs Between Male Housing and Moving Plate As shown in FIG. 3, the hood portion 21 of the male housing 20 is provided with thread ribs 23A to 23D. The thread ribs 23A to 23D are elongated protrusions that protrude from the inner wall surface of the hood portion 21 and extend in the front-rear direction. The thread ribs 23A to 23D are trapezoidal when viewed from a direction perpendicular to the protruding direction and the front-back direction. The thread ribs 23A to 23D have a semicircular shape in cross section when viewed from the front and rear directions. At the front ends of the thread ribs 23A to 23D, the area of the cross section perpendicular to the front-rear direction becomes smaller toward the front. At the rear ends of the yarn ribs 23A to 23D, the area of the cross section perpendicular to the front-rear direction becomes smaller toward the rear.

The moving plate 80 is assembled to the male housing 20 in parallel to the length direction (front-back direction) of the thread ribs 23A to 23D. The thread ribs 23A to 23D are crushed between the hood part 21 and the moving plate 80 in a plastically or elastically deformed state, thereby preventing the hood part 21 and the moving plate 80 from being twisted.

The thread ribs 23A to 23D are arranged at the same position on the inner wall surface of the hood portion 21 in the front-rear direction. For example, as shown in FIG. 14, the thread ribs 23A and 23C are at the same position in the front and back direction. As a result, the thread ribs 23A to 23D are brought into a collapsed state and an uncollapsed state at the same timing during the fitting process of both housings 20 and 50.

2-1. Thread ribs on the upper and lower opposing wall surfaces As shown in FIG. The wall surfaces 82B) constitute two sets of opposing wall surfaces (an upper opposing wall surface FA and a lower opposing wall surface FB). Specifically, a pair of opposing wall surfaces FA (upper opposing wall surface FA) is configured by a combination of one inner wall surface (upper inner wall surface 21A) and one outer wall surface (upper outer wall surface 82A) that face each other. There is. Furthermore, a pair of opposing wall surfaces FB (lower opposing wall surfaces FB) is configured by a combination of one inner wall surface (lower inner wall surface 21B) and one outer wall surface (lower outer wall surface 82B) that face each other.

As shown in FIG. 8, one of the two opposing wall surfaces (upper opposing wall surface FA, lower opposing wall surface FB) (lower opposing wall surface FB) is crushed and deformed when the male housing 20 and the moving plate 80 are assembled. Thread ribs 23A and 23B are provided. Thread ribs 23A, 23B are provided on the lower inner wall surface 21B of the lower opposing wall surface FB. In FIG. 6, thread ribs 23A are shown.

The thread ribs 23A, 23B are provided so as to extend forward at a predetermined distance (for example, the same distance as the thickness of the hood portion 21) from the rear end of the lower inner wall surface 21B (the end on the side where the female housing 50 is inserted). ing. The thread ribs 23A and 23B are respectively arranged slightly outside (on the left and right sides) of the center in the left-right direction on the lower inner wall surface 21B. The thread ribs 23A, 23B are arranged at symmetrical positions on the lower inner wall surface 21B with the center in the left-right direction in between.

As shown in FIGS. 6 and 7, of the two sets of opposing wall surfaces (upper opposing wall surface FA, lower opposing wall surface FB), the opposing wall surface (upper opposing wall surface FA) on which thread ribs 23A and 23B are not provided is in contact with the opposing wall surface (upper opposing wall surface FA). . That is, the upper outer wall surface 82A of the moving plate 80 comes into contact (surface contact) with the upper inner wall surface 21A of the male housing 20 without being deformed. As a result, when the male housing 20 and the moving plate 80 are assembled, the upper outer wall surface 82A directly contacts the upper inner wall surface 21A on which the thread ribs 23A and 23B are not arranged, so that the male housing 20 and the moving plate The vertical positional relationship of 80 can be made constant. Further, since the dimensions of other parts constituting the connector 10 can be varied based on the contact position (contact surface) between the upper inner wall surface 21A and the upper outer wall surface 82A, it is possible to suppress the accumulation of manufacturing tolerances.

2-2. Thread ribs on left and right opposing wall surfaces As shown in FIG. The wall surface 82D) constitutes two sets of opposing wall surfaces (left opposing wall surface FC, right opposing wall surface FD). Specifically, a pair of opposing wall surfaces FC (left opposing wall surface FC) is configured by a combination of one inner wall surface (left inner wall surface 21C) and one outer wall surface (left outer wall surface 82C) that face each other. There is. Furthermore, a pair of opposing wall surfaces FD (right opposing wall surface FD) is configured by a combination of one inner wall surface (right inner wall surface 21D) and one outer wall surface (right outer wall surface 82D) that face each other.

As shown in FIG. 9, one of the two opposing wall surfaces (left opposing wall surface FC, right opposing wall surface FD) (left opposing wall surface FC) is crushed and deformed when the male housing 20 and the moving plate 80 are assembled. Thread ribs 23C and 23D are provided. Thread ribs 23C and 23D are provided on the left inner wall surface 21C of the left opposing wall surface FC. In FIG. 10, thread ribs 23C are shown.

The thread ribs 23C, 23D extend forward at a predetermined distance (for example, the same length in the front-rear direction as the thread ribs 23A, 23B) from the rear end of the left inner wall surface 21C (the end on the side where the female housing 50 is inserted). It is set up like this. The thread ribs 23C and 23D are arranged near the upper end and near the lower end, respectively, on the left inner wall surface 21C. The thread ribs 23C and 23D are arranged at vertically symmetrical positions on both sides of the vertical center on the left inner wall surface 21C.

As shown in FIGS. 7 and 10, of the two sets of opposing wall surfaces (left opposing wall surface FC, right opposing wall surface FD), the opposing wall surface (right opposing wall surface FD) on which thread ribs 23C and 23D are not provided is in contact with each other. . That is, the right outer wall surface 82D of the moving plate 80 comes into contact (surface contact) with the right inner wall surface 21D of the male housing 20 without being deformed. As a result, when the male housing 20 and the moving plate 80 are assembled, the right outer wall surface 82D directly contacts the right inner wall surface 21D where the thread ribs 23C and 23D are not arranged, so that the male housing 20 and the moving plate The horizontal positional relationship of 80 can be made constant.

2-3. Thread ribs on opposing wall surfaces with orthogonal positional relationship The male housing 20 has two pairs of inner wall surfaces (an upper inner wall surface 21A and a lower inner wall surface 21B, a left inner wall surface 21C and a right inner wall surface 21D) whose opposing directions are perpendicular to each other. There is. The moving plate 80 has two pairs of outer wall surfaces (an upper outer wall surface 82A and a lower outer wall surface 82B, and a left outer wall surface 82C and a right outer wall surface 82D) whose opposing directions are perpendicular to each other.

The thread ribs 23A to 23D are connected to two sets of opposing wall surfaces (lower opposing wall surfaces) that are perpendicular to each other among four sets of opposing wall surfaces (upper opposing wall surface FA and lower opposing wall surface FB, left opposing wall surface FC and right opposing wall surface FD). It is arranged only on the wall surface FB and the left opposing wall surface FC). As a result, the upper opposing wall surface FA (upper inner wall surface 21A, upper outer wall surface 82A) contacts in the vertical direction, and the right opposing wall surface FD (right inner wall surface 21D, right outer wall surface 82D) contacts in the horizontal direction. Therefore, the positional relationship between the male housing 20 and the moving plate 80 can be kept constant in the orthogonal two-dimensional directions (vertical direction, horizontal direction).

2-4. Action of thread ribs The thread ribs 23A to 23D are crushed between the hood portion 21 and the moving plate 80 before the connection between the male terminal fitting 30 and the female terminal fitting 60 starts during the moving process of the moving plate 80. The start point of connection between the male terminal fitting 30 and the female terminal fitting 60 is the point in time when the contact between the male terminal fitting 30 and the female terminal fitting 60 begins. FIG. 5 shows a state before the connection between the male terminal fitting 30 and the female terminal fitting 60 starts. FIG. 5 is a sectional view taken along line BB in FIG.

6 to 11 are views of the same state as the connector 10 shown in FIG. 5 (a state before the connection of both terminal fittings 30, 60 is started). FIG. 6 shows a state in which the thread rib 23A is crushed between the hood portion 21 and the moving plate 80. FIG. 8 shows a state in which the thread ribs 23A, 23B are crushed. FIG. 9 shows a state in which the thread ribs 23C and 23D are crushed. FIG. 10 shows a state in which the thread ribs 23C are crushed.

When the male terminal fitting 30 and the female terminal fitting 60 start to connect, the thread ribs 23A to 23D are crushed between the hood part 21 and the moving plate 80 in a plastically or elastically deformed state, so that the hood part 21 Since prying of the moving plate 80 and the moving plate 80 is prevented, both terminal fittings 30 and 60 can be aligned.

As shown in FIG. 12, the thread ribs 23A to 23D are released from the collapsed state after the connection between the male terminal fitting 30 and the female terminal fitting 60 is started. FIG. 12 is a diagram showing a state in which both the housings 20 and 50 are fully fitted. For example, the thread ribs 23A to 23D are released from the collapsed state after the connection between the male terminal fitting 30 and the female terminal fitting 60 is started but before the connection is completed. FIG. 12 shows a state in which the thread ribs 23A are released from the collapsed state between the hood portion 21 and the moving plate 80.

As shown in FIG. 13, the right inner wall surface of the right recessed portion 25 contacts the right end portion 42Ab of the holding portion 42A. Thereby, the horizontal positional relationship between the male housing 20 and the holding portion 42A can be made constant.

In the male housing 20, the holding parts 42B to 42E of the male terminal holding part 40 may also be provided with thread ribs similar to the thread ribs 24A, 24B, and 25A for the holding part 42A. In this case, the holding parts 42B to 42E correspond to an example of the "second component" of the present disclosure.

4. Effects of Example 1 In the connector 10 of Example 1, only one of the two opposing wall surfaces (e.g., upper opposing wall surface FA, lower opposing wall surface FB) (e.g., lower opposing wall surface FB), Thread ribs 23A and 23B are provided which are crushed and deformed when the male housing 20 and the moving plate 80 are assembled. According to this configuration, when the male housing 20 and the moving plate 80 are assembled, the inner wall surface (for example, the upper inner wall surface 21A) and the outer wall surface (for example, the upper outer wall surface 82A), the positional relationship between the male housing 20 and the moving plate 80 can be kept constant.

In the connector 10 of the first embodiment, the male housing 20 has two pairs of inner wall surfaces (an upper inner wall surface 21A and a lower inner wall surface 21B, a left inner wall surface 21C and a right inner wall surface 21D) whose opposing directions are perpendicular to each other. The plate 80 has two pairs of outer wall surfaces (an upper outer wall surface 82A and a lower outer wall surface 82B, and a left outer wall surface 82C and a right outer wall surface 82D) whose opposing directions are perpendicular to each other. The thread ribs 23A to 23D are arranged only on two sets of opposing wall surfaces (lower opposing wall surface FB, left opposing wall surface FC) that are perpendicular to each other among the four opposing wall surfaces FA to FD. According to this configuration, the positional relationship between the male housing 20 and the moving plate 80 can be kept constant in the orthogonal two-dimensional directions (vertical direction, horizontal direction).

[Example 2]
The connector of Example 2 differs from Example 1 in the arrangement of thread ribs. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

In the connector of Example 2, the positions of the front ends of the plurality of thread ribs in the assembly direction are different from each other. For example, as shown in FIG. 15, a thread rib 223A is provided in place of the thread rib 23A of the first embodiment. A portion of the thread rib 223A is located at a position overlapping the thread rib 23D in the front-rear direction. In the hood portion 21, the front end 223Aa of the thread rib 223A in the assembly direction is located further back in the assembly direction than the front end 23Da of the thread rib 23D in the assembly direction. Here, the assembly direction of the hood portion 21 is the direction toward the side where the moving plate 80 is assembled (the negative direction of the X-axis).

In the process of assembling the male housing 20 and the moving plate 80, the fitting resistance due to the crushing deformation of the thread ribs 223A, 23B to 23D reaches its maximum when the thread ribs 223A, 23B to 23D begin to collapse. Therefore, by making the formation ranges of the thread rib 223A and the thread ribs 23B to 23D different in the assembly direction, the peak value of the fitting resistance can be reduced.
