BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector with a guide member provided with a guide member for preventing bending of a male contact.

[0002]

2. Description of the Related Art A conventional connector with a guide member provided with a guide member for preventing bending of male contacts arranged in a housing will be described with reference to FIGS. -116985). FIG. 12 is a longitudinal sectional view showing a state before the female connector and the male connector are fitted, and FIG. 13 is a longitudinal sectional view showing a state where the female connector and the male connector are fitted.

The housing 12 of the female connector 10 includes
A plurality of male contacts 14 are arranged, and the tip portions 14a of the male contacts 14 pass through through holes formed in the guide member 16, respectively. Guide member 1
6 is temporarily fixed in the housing 12 by fitting a convex portion 12a formed in the housing 12 into a concave portion 16a of the guide member. When the female connector 10 and the male connector 20 are fitted together, the guide member 16 is pushed by the male connector 20 and moves to the rear end of the male contact 14 as shown in FIG. . This allows
The male contact 14 and the female contact 22 are fitted.

As described above, in the connector with the guide member, the male contact is prevented from being bent by inserting the tip of the male contact into the through hole formed in the guide member, and the female connector is provided. When the male connector is fitted with the male connector, the guide member is configured to be pushed by the male connector and move to the rear end of the male contact.

[0005]

Until the mating of the male connector and the female connector is started, the guide member is held at the tip of the male contact at the tip of the male contact in order to prevent bending of the male contact. The contacts are temporarily fixed in the housing in which the contacts are arranged, but if the temporary fixing is too strong, it becomes difficult to fit the male connector and the female connector, and thus the contacts are weakly temporarily fixed. For this reason, in the conventional connector with a guide member, when vibration or something accidentally hits the guide member during transportation, the guide member moves from the front end portion to the rear end portion of the male contact and the guide member moves. There is a problem that the temporary fixing may be released.

In view of the above circumstances, the present invention is intended to prevent the guide member from being inadvertently moved due to vibration and the like during transportation until the male connector and the female connector are mated. It is another object of the present invention to provide a connector with a guide member that prevents the provisional fixing and facilitates the fitting when the fitting is performed.

[0007]

According to the present invention, there is provided a connector with a guide member having a first housing and a male contact arranged in the first housing and extending in a fitting direction. A first connector, a second connector having a second housing fitted with the first housing, and a through-hole through which the male contact penetrates are formed , and the first and second connectors are connected to each other. >; and a guide member which is pushed by the second connector when you fit moves to the rear end of the male contact, the guide member with the connector, (1) the first housing, the male Before mold contact

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the connector with a guide member of the present invention will be described below with reference to the drawings. FIGS. 1 to 7 are horizontal sectional views showing the outline of the plug housing, showing only the outline, and showing the cross section of the guide member by oblique lines, from the start to the end of the fitting of the connector with the guide member of the present invention.

First, the structure of the connector with a guide member of the present embodiment will be described with reference to FIG. In the connector 30 with a guide member, a cap housing 40 fitted to each other is provided.
And a plug housing 50. A plurality of male contacts 42 are arranged in the cap housing 40. A plate-like guide member 60 substantially parallel to the fitting surface is accommodated in the cap housing 40. The guide member 60 includes a plurality of male contacts 4
A plurality of through holes 61 through which each 2 penetrates are formed.

On the bottom wall 44 of the cap housing 40,
Two projections 44 having a surface 43a substantially orthogonal to the fitting direction
a is formed, and the projection 44a is
It is engaged with a pair of L-shaped legs 60a having a surface 63a formed at 0 and orthogonal to the fitting direction. Each L-shaped leg 6
0a is adjacent to the bottom wall 44 of the cap housing 40
It extends from the edge of the guide member 60 in the fitting direction and is elastic.
And a spring arm 60a1 having
With the hook part 60a2 provided integrally with the front end.
You. The engagement between the projection 44a and the L-shaped leg 60a is performed by abutting the two surfaces 43a and 63a substantially perpendicular to the fitting direction. Inadvertent movement toward the section is prevented. The upper surface of the projection 44a has a downward slope from the center of the upper surface toward the rear (in the direction toward the rear end of the male contact 42), so that the connector can be easily detached. . Further, two projections 44b are also formed on the bottom wall 44 of the cap housing 40. When the stopper leg 60b formed on the guide member 60 comes into contact with the projection 44b, the guide member 60 falls out of the cap housing 40. Has been prevented. Further, the cap housing 4
Two projections 44c are formed on the bottom wall of the zero, and downward slopes are formed from the center of the upper surface of the projection 44c toward the front and the rear, respectively. In addition, this projection 4
4c, the plug housing 50 is the cap housing 4
When the plug housing 50 engages with the temporary stop leg 60c formed on the guide member 60 when the plug housing 50 is slightly engaged with the guide member 60, the guide member
0 is temporarily stopped. This prevents collision between the male contacts 42 arranged in the cap housing 40 and the female contacts (not shown) arranged in the plug housing 50, and these contacts are securely fitted. Furthermore, two projections 44d are formed on the bottom wall of the cap housing 40, and the projections 44d
Deflects the L-shaped leg 60d as described later. Note that the projection 4 is also provided on the upper wall (not shown) of the cap housing 40.
4a, 44b, 44c and 44d (not shown) are formed two each.

The plug housing 50 is inserted between a pair of L-shaped legs 60a to bend the pair of L-shaped legs 60a in directions opposite to each other, thereby forming the L-shaped legs 60a.
A wedge-shaped projection 50a for releasing the engagement between the projection and the projection 44a is formed. Further, as described later, the male contacts 42
A projection 50b is also formed for smoothing the movement of the guide member 60 when is slightly bent.

Next, the process from the start to the end of the fitting of the connector 30 with a guide member will be described. As shown in FIG. 1, when the cap housing 40 and the plug housing 50 are not fitted at all, the surface 43a of the projection 44a of the cap housing 40 and the L-shaped leg 60a When the surface 63a abuts, the protrusion 44a and the L-shaped leg 60a are strongly engaged in the rear end direction of the male contact 42, and the male contact 42
The guide member 60 is prevented from accidentally moving toward the rear end. On the other hand, the projection 4 of the cap housing 40
The guide member 60 is prevented from dropping out of the cap housing 40 due to the contact of the stopper leg 60b with the stopper leg 4b. Further, when the cap housing 40 and the plug housing 50 are not fitted, the tip of the male contact 42 does not pass through the through hole 61 of the guide member 60, and is protected from external force and the like. As shown in FIG.
When the cap housing 40 and the plug housing 50 are slightly fitted, the tip of the wedge-shaped projection 50a enters between the pair of L-shaped legs 60a. When the cap housing 40 and the plug housing 50 are further fitted, as shown in FIG. 3, the wedge-shaped projection 50a enters deeply between the pair of L-shaped legs 60a immediately above the projection 44a, and the pair of L-shaped The legs 60a are largely bent in opposite directions. As is clear from FIGS. 2 and 3, the L-shaped legs
60a flexes along the bottom wall 44 of the cap housing 40
Therefore, a large space is required for the L-shaped leg 60a to bend.
do not need. The fitting between the cap housing 40 and the plug housing 50 further proceeds, and the wedge-shaped projection 50a is
4, the protrusion 44a and the L-shaped leg 60a are disengaged from each other, and the suspension leg 60c is moved further deeply between the pair of L-shaped legs 60a.
And the projection 44c are engaged, and the guide member 60 is temporarily stopped. When the fitting between the cap housing 40 and the plug housing 50 further proceeds, as shown in FIG. 5, the guide member 60 is temporarily stopped because the temporary stop leg 60c and the projection 44c are engaged. Plug housing 5
0 approaches the guide member 60. As the fitting of the cap housing 40 and the plug housing 50 further proceeds, as shown in FIG.
0 abuts against the base surface 62. From this state, the fitting of the male contact 42 and the female contact (not shown) is started, so that the collision between the male contact 42 and the female contact is prevented, and these contacts are fitted smoothly. Further, when the fitting is advanced while the plug housing 50 is kept in contact with the guide member 60, the suspension leg 60c advances over the protrusion 44c, and as shown in FIG.
The male contact 42 and the female contact (not shown) are fitted and finished.

Here, the plug housing 5 is detached from the male contact 42 and the female contact (not shown).
0 in the opposite direction to the fitting direction, the wedge-shaped projection 50a
Is engaged with the pair of L-shaped legs 60a,
In the release direction. When the plug housing 50 is further pulled in the detaching direction, the pair of L-shaped legs 60a
a, and the suspension leg 60c is also a projection 44c.
Get over. When the plug housing 50 is further pulled in the detaching direction, the stopper leg 60b comes into contact with the projection 44b, the movement of the guide member is stopped, and the plug housing 50 is completely detached from the cap housing 40.

Next, referring to FIGS. 8 to 11, for example, since the male contact 42 (see FIG. 1) is slightly bent, friction occurs with the through hole 61 (see FIG. 1). From the start of fitting of the connector 30 with a guide member to the end of fitting when the connector does not move smoothly will be described. The state shown in FIG. 8 is a state in which the male member (not shown) is slightly bent, causing friction with the through-hole 61 and the guide member 60 not moving smoothly, and is shown in FIG. The plug housing 50 is fitted slightly deeper into the cap housing 40 as compared with the state in which the plug member 50 is moved, but the movement of the guide member 60 is small. It is clear from this. When the movement of the guide member 60 is small, as shown in FIG.
0b contacts the L-shaped leg 60d of the guide member 60.
When the fitting is further advanced, as shown in FIG. 10, the L-shaped leg 60d is pressed by the projection 50b, so that the guide member 60 moves in the fitting direction slightly, and the tip of the male contact 42 penetrates. It is inserted slightly deeper into the hole 61. When the fitting is further promoted, as shown in FIG. 11, the sloped surface 45a of the projection 44d formed on the inner wall of the cap housing 40 causes the sloped surface 63a of the L-shaped leg 60d to extend in a direction substantially orthogonal to the fitting direction. Pressed. Thereby, as shown in FIG. 5 described above, the protrusion 50b and the L-shaped leg 60d do not interfere with each other. When the fitting is further advanced, FIG.
The fitting is completed by the movement as shown in FIG. As described above, since the male contact is slightly bent, friction occurs with the through hole 61, so that the fitting can be smoothly finished even when the guide member 60 is not moving smoothly.

The legs 60a and 60d may have a shape other than an L-shape such as a T-shape or a J-shape.
