Description

Connector device

This disclosure relates to a connector device.

Conventionally, there is a connector device provided with a device-side connector mounted on the case of a device mounted on a vehicle and a wire-side connector provided at the end of an electric wire and electrically connected to the device-side connector. The device-side connector has a device-side terminal that is electrically connected to a device-side terminal arranged inside the case, and a device-side connector housing in which the device-side terminal is arranged inside. The wire-side connector has a wire-side terminal to which the wire is electrically connected, and a wire-side connector housing in which the wire-side terminal is arranged inside and the device-side connector housing is inserted. Then, for example, the device side terminal is a male terminal and the electric wire side terminal is a female terminal. When connecting the device-side connector and the wire-side connector, the device-side terminal is inserted into the wire-side terminal, so that the device-side terminal and the wire-side terminal are electrically connected.

In such a connector device, for example, as described in Patent Document 1, by screwing a fitting nut provided on the device-side connector and a fitting bolt provided on the electric wire-side connector, the fitting bolt is screwed. There is a configuration that assists the connection between the device side connector and the electric wire side connector.

Japanese Unexamined Patent Publication No. 2011-48949

By the way, when inserting the device-side terminal into the wire-side terminal in order to connect the device-side connector and the wire-side connector, if the electric wire-side terminal, which is a female terminal, presses the device-side terminal, which is a male terminal, with a large pressing force. Since the frictional force between the terminals becomes large, a larger force is required to insert the device-side terminal into the wire-side terminal. In a connector device configured to assist the connection between the device-side connector and the wire-side connector with the fitting nut and fitting bolt, the fitting bolt is screwed into the fitting nut to connect the device-side terminal to the wire-side terminal. It can assist the insertion.

However, the fitting nut and the fitting bolt are generally provided at one location on the outer periphery of the device-side terminal and the wire-side terminal in the device-side connector and the wire-side connector. Further, the force required to insert the device-side terminal into the wire-side terminal is generally larger than the force required to insert the device-side connector housing into the wire-side connector housing. Therefore, when the fitting bolt is screwed into the fitting nut, the electric wire side connector may be tilted with respect to the device side connector with the screwed portion between the fitting nut and the fitting bolt as a fulcrum. Then, the insertion of the device-side terminal into the wire-side terminal is advanced with the wire-side terminal tilted with respect to the device-side terminal. In this case, the terminal may be damaged at the contact portion between the device side terminal and the electric wire side terminal, for example, the terminal may be scraped.

The purpose of the present disclosure is to provide a connector device capable of suppressing damage to terminals.

The connector device of one aspect of the present disclosure includes a first connector having a first terminal and a second connector having a second terminal electrically connected to the first terminal and connected to the first connector. The first connector includes a first connector housing having a tubular first insertion portion and a first tightening member, and the second connector includes a tubular second insertion portion. It has a second connector housing and a second tightening member that inserts the first insertion portion into the second insertion portion by screwing with the first tightening member, and the first terminal is the first. It has a first connection portion that is arranged inside the insertion portion and extends along the axial direction of the first insertion portion, and the second terminal is arranged inside the second insertion portion and has a shaft of the second insertion portion. It has a second connection portion extending along the direction, and the first connection portion and the second connection portion are the first connection portion as the first insertion portion is inserted into the second insertion portion. And one of the second connecting portions is electrically connected by being inserted into the other, and the first insertion portion is formed on the outer peripheral surface of the first insertion portion by the first insertion portion. The second guide portion has a first guide portion extending along the axial direction, and the second insertion portion has a second guide portion extending along the axial direction of the second insertion portion on the inner peripheral surface of the second insertion portion.

[Explanation of Embodiments of the present disclosure]
First, embodiments of the present disclosure will be listed and described.
The connector device of the present disclosure is
[1] A first connector having a first terminal and a second connector having a second terminal electrically connected to the first terminal and connected to the first connector are provided, and the first connector is provided. The second connector has a first connector housing having a tubular first insertion portion and a first tightening member, and the second connector has a second connector housing having a tubular second insertion portion. It has a second tightening member that inserts the first insertion portion into the second insertion portion by screwing with the first tightening member, and the first terminal is arranged inside the first insertion portion. It has a first connection portion extending along the axial direction of the first insertion portion, and the second terminal is arranged inside the second insertion portion and extends along the axial direction of the second insertion portion. It has a connection portion, and the first connection portion and the second connection portion are of the first connection portion and the second connection portion as the first insertion portion is inserted into the second insertion portion. One of them is electrically connected by being inserted into the other, and the first insertion portion extends on the outer peripheral surface of the first insertion portion along the axial direction of the first insertion portion. The first guide portion is provided, and the second insertion portion has one or more second guide portions extending along the axial direction of the second insertion portion on the inner peripheral surface of the second insertion portion. One of the first guide portion and the second guide portion is a guide groove, and the other is the second of the first insertion portion when the first insertion portion is inserted into the second insertion portion. It is a connector device which is a guide convex portion which is inserted into the guide groove along a direction parallel to the insertion direction into the insertion portion and fits into the guide groove.

According to this configuration, the guide protrusion inserted into the guide groove along the direction parallel to the insertion direction fits into the guide groove. Therefore, the inclination of the guide protrusion with respect to the guide groove is regulated by the inner peripheral surface of the guide groove. That is, the inclination of the guide convex portion with respect to the axial direction of the first insertion portion or the axial direction of the second insertion portion is regulated by the inner peripheral surface of the guide groove. Therefore, when the first insertion portion is inserted into the second insertion portion in order to connect the first connector and the second connector, the second insertion portion is inclined relative to the first insertion portion. It is suppressed by the fitted first guide portion and second guide portion. Therefore, it is possible to prevent the second connection portion extending along the axial direction of the second insertion portion from being relatively inclined with respect to the first connection portion extending along the axial direction of the first insertion portion. Therefore, the first connection portion and the second connection portion can be electrically connected in a state where the second connection portion is suppressed from being tilted relative to the first connection portion. As a result, damage to the first connection portion and the second connection portion, that is, damage to the first terminal and the second terminal can be suppressed.

[2] When connecting the first connector and the second connector, the insertion into the guide groove is performed before the insertion into the other of the first connection portion and the second connection portion is started. It is preferable that the insertion of the guide protrusion is started.

According to this configuration, when the insertion into one of the first connecting portion and the second connecting portion is started, at least a part of the guide convex portion is fitted in the guide groove. Therefore, when connecting the first connector and the second connector, the first connection portion and the second connection portion are formed by the first guide portion and the second guide portion, so that the second connection portion is connected to the first connection portion. Connection with each other can be started with the relative inclination suppressed. As a result, when connecting the first connector and the second connector, the first connection portion and the second connection portion are damaged, that is, the first terminal and the first connection portion are damaged from the start of the connection between the first connection portion and the second connection portion. Damage to the second terminal can be suppressed.

[3] When the first connector is viewed from the axial direction of the first insertion portion, a straight line passing through the center of the first insertion portion and the center of the first tightening member is the first straight line, and the first insertion portion. The portion has two first guide portions arranged at both ends of the first insertion portion in a direction intersecting the first straight line, and the second connector is connected from the axial direction of the second insertion portion. As seen, the straight line passing through the center of the second insertion portion and the center of the second tightening member is the second straight line, and the second insertion portion is the second insertion portion in the direction intersecting the second straight line. It is preferable to have the two second guide portions arranged at both ends of the inner peripheral surface of the above.

According to this configuration, the first connector and the second connector are provided as compared with the case where the first insertion portion has only one first guide portion and the second insertion portion has only one second guide portion. It is easier to prevent the second insertion portion from tilting relative to the first insertion portion when connecting. Further, the first insertion portion has first guide portions at both ends of the first insertion portion in the first straight line direction, and the second insertion portion has both ends of the inner peripheral surface of the second insertion portion in the second straight line direction. Compared with the case where the second guide portion is provided in the portion, it is easier to prevent the second insertion portion from being tilted relative to the first insertion portion when the first connector and the second connector are connected. Therefore, when connecting the first connector and the second connector, it becomes easier to suppress the second connection portion from being tilted relative to the first connection portion. As a result, damage to the first connection portion and the second connection portion, that is, damage to the first terminal and the second terminal can be further suppressed.

[4] The first connector housing has a flange portion extending outward from the outer peripheral surface of the first insertion portion, and the first guide portion is the guide convex portion and the flange portion. It is preferable that they are provided integrally.

According to this configuration, the strength of the first guide portion can be increased as compared with the case where the first guide portion is not provided integrally with the flange portion. Therefore, the first guide portion can withstand a larger load applied to the first guide portion when the second insertion portion tries to incline relative to the first insertion portion.

Further, each of the second guide portions 48 has a constant cross-sectional shape along the axial direction X2. The positions of the two second guide portions 48 are the same in the lateral direction of the second insertion portion 42 when viewed from the axial direction X2.

Here, the direction in which the first insertion portion 22 is inserted into the second insertion portion 42 when the first connector 20 and the second connector 40 are connected is the insertion direction X3. When connecting the first connector 20 and the second connector 40, the first guide portion 28 is inserted along the direction parallel to the insertion direction X3 as the first insertion portion 22 is inserted into the second insertion portion 42. Is inserted into the second guide portion 48. In the present embodiment, the first guide portion 28 is inserted into the second guide portion 48 along the same direction as the insertion direction X3. The portion of the first guide portion 28 inserted into the second guide portion 48 fits into the second guide portion 48. Then, in the portion where the first guide portion 28 is fitted to the second guide portion 48, the gap between the outer peripheral surface of the first guide portion 28 and the inner peripheral surface of the second guide portion 48 is the first guide portion 28. It is smaller than the gap between the outer peripheral surface of the first insertion portion 22 excluding the above and the inner peripheral surface of the second insertion portion 42 excluding the second guide portion 48. Further, the gap between the outer peripheral surface of the first guide portion 28 and the inner peripheral surface of the second guide portion 48 is a relative movement between the first guide portion 28 and the second guide portion 48 in the direction parallel to the insertion direction X3. The size is such that the inner peripheral surface of the second guide portion 48, which is a guide groove, can suppress the inclination of the first guide portion 28, which is a guide convex portion, with respect to the axial direction X2.

(Structure of the second terminal 51)
As shown in FIGS. 1 and 2, the second connector 40 has two second terminals 51 in the same number as the first terminal 31. The second terminal 51 is made of a conductive material. As the material of the second terminal 51, for example, a metal material such as copper, a copper alloy, aluminum, or an aluminum alloy can be used.

The two second terminals 51 are arranged with respect to the second connector housing 41 so as to be aligned in the longitudinal direction of the second insertion portion 42 when viewed from the axial direction X2. An electric wire (not shown) is electrically connected to each of the second terminals 51.

Each second terminal 51 has a second connection portion 52 arranged inside the second insertion portion 42. At each second terminal 51, the second connection portion 52 extends along the axial direction X2. The second connecting portion 52 has a shape into which the first connecting portion 32 can be inserted. That is, the second terminal 51 of this embodiment is a female terminal. In the present embodiment, the second connecting portion 52 has a cylindrical shape. The two second connecting portions 52 are arranged in the longitudinal direction of the second inserting portion 42 when viewed from the axial direction X2. Further, the two second connecting portions 52 have the same position in the lateral direction of the second inserting portion 42 when viewed from the axial direction X2. The tip of the second connecting portion 52 is located closer to the proximal end side of the second inserting portion 42 than the tip of the second inserting portion 42 in the axial direction X2. The tip of the second connecting portion 52 is the end of the second connecting portion 52 on the tip side of both ends of the axial direction X2.

As shown in FIG. 4, in the present embodiment, when viewed from the axial direction X2, the center O22 of the second tightening member 44 and the center of the two second connecting portions 52 are in the longitudinal direction of the second inserting portion 42. The position is the same. Therefore, when viewed from the axial direction X2, the second insertion portion 42 has second guide portions on both sides in a direction orthogonal to the straight line passing through the center O22 of the second tightening member 44 and the center of the two second connection portions 52, respectively. Has 48.

(Connection between the first connector 20 and the second connector 40)
Next, the connection between the first connector 20 and the second connector 40 will be described together with the operation of the present embodiment.

As shown in FIG. 2, when connecting the first connector 20 and the second connector 40, the first connector 20 and the second connector 40 are connected to the tip of the first insertion portion 22 and the second insertion portion 42. Place it so that it faces the tip. After that, the second connector 40 is moved to the first connector 20 side so that the first insertion portion 22 is inserted into the second insertion portion 42. At this time, the first guide portion 28 is inserted into the second guide portion 48 along the direction parallel to the insertion direction X3 of the first insertion portion 22 into the second insertion portion 42. The portion of the first guide portion 28 inserted into the second guide portion 48 fits into the second guide portion 48 in a state where relative movement in the axial direction X2 with respect to the second guide portion 48 is permitted. As the insertion of the first guide portion 28 into the second guide portion 48 progresses, the first guide portion 28 and the second guide portion 48 suppress the inclination of the second insertion portion 42 with respect to the first insertion portion 22. become. That is, the inclination of the second insertion portion 42 with respect to the first insertion portion 22 is suppressed so that the axial direction X2 is inclined with respect to the axial direction X1 (that is, the central axis L2 is inclined with respect to the central axis L1). It becomes a state. Therefore, it is possible to prevent the second connection portion 52 from being tilted with respect to the first connection portion 32.

When the second connector 40 is further moved toward the first connector 20 while the first insertion portion 22 is inserted into the second insertion portion 42, the tip of the male screw portion 44b of the second tightening member 44 becomes the first tightening member 27. Is inserted into the opening of the female screw hole 27b. At this time, the tip of the first connecting portion 32 and the tip of the second connecting portion 52 are separated from each other in the axial direction X1 or the axial direction X2, that is, the insertion direction X3, and the first connecting portion 32 is connected to the second connecting portion 52. Insertion has not started.

Then, by screwing the second tightening member 44 into the first tightening member 27, the second connector 40 is further moved to the first connector 20 side. Then, the tip of the first connecting portion 32 begins to be inserted into the second connecting portion 52. When the first connecting portion 32 begins to be inserted into the second connecting portion 52, the first guide portion 28 is tilted by the first guide portion 28 and the second guide portion 48 with respect to the first insertion portion 22. It is inserted into the second guide portion 48 enough to suppress the above. Therefore, it is provided so as to extend along the axial direction X2 inside the second insertion portion 42 with respect to the first connection portion 32 provided so as to extend along the axial direction X1 inside the first insertion portion 22. The first connecting portion 32 starts to be inserted into the second connecting portion 52 in a state where the tilting of the second connecting portion 52 is suppressed.

Then, the second tightening member 44 is screwed into the first tightening member 27 until the holding portion 43 comes into contact with the contact surface 27a. At this time, the first guide portion 28 and the second guide portion 48 prevent the second insertion portion 42 from tilting with respect to the first insertion portion 22. Therefore, even if it is difficult for the first connecting portion 32 to be inserted into the second connecting portion 52 due to the frictional force between the first connecting portion 32 and the second connecting portion 52, the first connecting portion 32 is not inserted. Therefore, it is possible to prevent the first connection portion 32 from being inserted into the second connection portion 52 in a state where the second connection portion 52 is tilted.

As shown in FIG. 3, when the holding portion 43 comes into contact with the contact surface 27a, the connection between the first connector 20 and the second connector 40 is completed. The E-ring 45 is arranged in the accommodating recess 27c. In a state where the first connector 20 and the second connector 40 are connected, the first connection portion 32 is inserted into the second connection portion 52, so that the first connection portion 32 and the second connection portion 52 are in pressure contact with each other. The first connection portion 32 and the second connection portion 52 are electrically connected to each other.

The effect of this embodiment will be described.
(1) The connector device 10 has a first connector 20 having a first terminal 31 and a second connector 40 having a second terminal 51 electrically connected to the first terminal 31 and connected to the first connector 20. And have. The first connector 20 has a first connector housing 21 provided with a first insertion portion 22 having a cylindrical shape, and a first tightening member 27. The second connector 40 inserts the first insertion portion 22 into the second insertion portion 42 by screwing the second connector housing 41 having the second insertion portion 42 having a cylindrical shape and the first tightening member 27. It has a second tightening member 44. The first terminal 31 has a first connection portion 32 arranged inside the first insertion portion 22 and extending along the axial direction X1. The second terminal 51 has a second connection portion 52 arranged inside the second insertion portion 42 and extending along the axial direction X2. The first connection portion 32 and the second connection portion 52 are electrically connected to each other by inserting the first connection portion 32 into the second connection portion 52 as the first insertion portion 22 is inserted into the second insertion portion 42. It is connected to the target. The first insertion portion 22 has a first guide portion 28 extending along the axial direction X1 on the outer peripheral surface of the first insertion portion 22. The second insertion portion 42 has a second guide portion 48 extending along the axial direction X1 on the inner peripheral surface of the second insertion portion 42. The second guide portion 48 is a guide groove. The first guide portion 28 is provided in the guide groove along a direction parallel to the insertion direction X3 of the first insertion portion 22 into the second insertion portion 42 when the first insertion portion 22 is inserted into the second insertion portion 42. It is a guide convex portion that is inserted and fits into the guide groove.

According to this configuration, the guide protrusion inserted into the guide groove along the direction parallel to the insertion direction X3 fits into the guide groove. In the present embodiment, the first guide portion 28 inserted into the second guide portion 48 along the direction parallel to the insertion direction X3 fits into the second guide portion 48. Therefore, the inclination of the first guide portion 28, which is the guide convex portion, with respect to the second guide portion 48, which is the guide groove, is regulated by the inner peripheral surface of the second guide portion 48. That is, the inclination of the first guide portion 28, which is the guide convex portion, with respect to the axial direction X2 is regulated by the inner peripheral surface of the second guide portion 48, which is the guide groove. Therefore, when the first insertion portion 22 is inserted into the second insertion portion 42 in order to connect the first connector 20 and the second connector 40, the second insertion portion 42 is relative to the first insertion portion 22. Tilt is suppressed by the first guide portion 28 and the second guide portion 48 fitted to each other. Therefore, it is suppressed that the second connecting portion 52 extending along the axial direction X2 is relatively inclined with respect to the first connecting portion 32 extending along the axial direction X1. Therefore, the first connection portion 32 can be inserted into the second connection portion 52 in a state where the second connection portion 52 is suppressed from being tilted relative to the first connection portion 32. As a result, damage to the first connection portion 32 and the second connection portion 52, that is, damage to the first terminal 31 and the second terminal 51 can be suppressed.

(2) When connecting the first connector 20 and the second connector 40, the first guide to the second guide portion 48 is made before the insertion of the first connection portion 32 into the second connection portion 52 is started. The insertion of the portion 28 is started.

It will be fitted to 48. Therefore, when connecting the first connector 20 and the second connector 40, the first connecting portion 32 and the second connecting portion 52 are connected to the first connecting portion 32 by the first guide portion 28 and the second guide portion 48. On the other hand, the connection between the second connecting portions 52 can be started in a state where the relative inclination is suppressed. As a result, when the first connector 20 and the second connector 40 are connected, the first connection portion 32 and the second connection portion 52 are damaged from the start of the connection between the first connection portion 32 and the second connection portion 52. That is, damage to the first terminal 31 and the second terminal 51 can be suppressed.

(3) When the first connector 20 is viewed from the axial direction X1, the straight line passing through the center O11 of the first insertion portion 22 and the center O12 of the first tightening member 27 is the first straight line L11, and the first insertion portion 22 is , The first guide portions 28 are provided at both ends of the first insertion portion 22 in the direction intersecting the first straight line L11.

The second guide portions 48 are provided at both ends of the inner peripheral surface of the second insertion portion 42 in the direction intersecting the straight line L21.

According to this configuration, the first connector 20 and the second insertion portion 42 have only one first guide portion 28 and the second insertion portion 42 has only one second guide portion 48. When connecting to the second connector 40, it is easier to prevent the second insertion portion 42 from tilting relative to the first insertion portion 22. Further, the first insertion portion 22 has first guide portions 28 at both ends of the first insertion portion 22 in the direction of the first straight line L11, and the second insertion portion 42 is a second insertion portion 42 in the direction of the second straight line L21. Compared to the case where the second guide portions 48 are provided at both ends of the inner peripheral surface, the second insertion portion 42 is relative to the first insertion portion 22 when connecting the first connector 20 and the second connector 40. It is easier to suppress the inclination to. Therefore, when the first connector 20 and the second connector 40 are connected, it becomes easier to prevent the second connecting portion 52 from tilting relative to the first connecting portion 32. As a result, damage to the first connection portion 32 and the second connection portion 52, that is, damage to the first terminal 31 and the second terminal 51 can be further suppressed.

In the present embodiment, when the first connector 20 is viewed from the axial direction X1, the first insertion portion 22 is two first inserted portions arranged at both ends of the first insertion portion 22 in a direction orthogonal to the first straight line L11.

It has a portion 48. Therefore, it is possible to more effectively suppress the second insertion portion 42 from being tilted relative to the first insertion portion 22 when the first connector 20 and the second connector 40 are connected. Therefore, when the first connector 20 and the second connector 40 are connected, it is possible to more effectively suppress the second connection portion 52 from being tilted relative to the first connection portion 32. As a result, damage to the first connection portion 32 and the second connection portion 52, that is, damage to the first terminal 31 and the second terminal 51 can be further suppressed.

(4) The first connector housing 21 has a flange portion 24 extending outward from the outer peripheral surface of the first insertion portion 22. The first guide portion 28 is a guide convex portion and is provided integrally with the flange portion 24.

According to this configuration, the strength of the first guide portion 28 can be increased as compared with the case where the first guide portion 28 is not provided integrally with the flange portion 24. Therefore, the first guide portion 28 can withstand a larger load applied to the first guide portion 28 when the second insertion portion 42 tries to incline relative to the first insertion portion 22.
