Field of the Invention The present invention relates to a press-fit joint connector formed by connecting connector housings in multiple stages. 2. Description of the Related Art FIGS. 7 to 15 show such a press-fitting joint connector. 7 is a perspective view of the connector housing, FIG. 8 is a perspective view of the terminal assembly, FIG. 9 is a perspective view of the connector housing with the terminal assembly assembled, FIG. 10 is a plan view of the connector housing,
11 is a cross-sectional view of the connector housing, FIG. 12 is a cross-sectional view taken along line AA of FIG. 11 when the terminals are mounted, FIG. 13 is a cross-sectional view of the connector housing with the terminals mounted, and FIG. Sectional view, FIG.
(A), (B) is a sectional view showing the state of contact between the tab portion and the tab contact portion due to positional displacement between both terminals. In FIGS. 7 to 13, a connector housing 1 has upper and lower surfaces formed as connecting surfaces 1a and 1b, respectively, and is provided on both sides of the upper connecting surface 1a and substantially the entire front surface. The housing lock projection 2 has a housing lock groove 3 on the corresponding lower connecting surface 1b.
(Shown in FIG. 11 and the like) are provided. [0004] The connector housing 1 is provided with a plurality of terminal accommodating chambers 5 each partitioned by each cavity wall 4, and each of the terminal accommodating chambers 5 is provided with a locked portion 1c. The terminals 6 are respectively housed in the respective terminal housing chambers 5 by insertion. Prior to assembly into the connector housing 1, the plurality of terminals 6 are configured as a terminal assembly 7 shown in FIG. 8, and the terminal assembly 7 is formed of a plurality of terminals 6 and a plurality of terminals 6 arranged in parallel. And a carrier section 8 connecting the terminals 6.
The terminal assembly 7 is formed by punching a plate-shaped conductive metal into a predetermined shape, bending the punched conductive metal to form a plurality of terminals 6, and then forming a carrier portion 8 connecting the plurality of terminals 6 to a valley. Is formed by bending into a continuous shape. That is, by bending the carrier portion 8, the terminal pitch is narrowed to form a terminal assembly 7 having a narrow pitch between terminals. [0005] In the process of assembling the connector housing 1, a portion of the carrier portion 8 located between the terminals 6 where no electrical connection is required is cut, and a cut space 9 is formed in this portion. . The terminal 6 is a wire press-contact portion 6 to which the wire W is pressed.
a, a locking portion 6b that is locked to the connector housing 1 and has a spring property, and a tab portion 6c that protrudes toward the upper connecting surface 1a and has a contact surface in a direction orthogonal to the terminal insertion / drawing direction.
The tab portion 6c inserted from the lower connecting surface 1b is brought into contact with the tab contact portion 6d having a spring property (shown in FIG. 13 and the like) and the opposite surface of the tab portion contacted by the tab contact portion 6d. And a supporting tab receiving portion 6e (shown in FIG. 13 and the like). As shown in FIG. 12, the terminal 6 is at the mounting position, and the locking portion 6 b is locked to the locked portion 1 c of the connector housing 1. Further, a tab insertion hole 10 is formed in the lower surface of each terminal accommodating chamber 5, and the tab insertion hole 10 is configured to coincide with the position of the tab contact portion 6d of the terminal 6 at the mounting position. Next, the operation of mounting terminals on the connector housing 1 and the operation of connecting the connector housings 1 will be described. The terminal assembly 7 is inserted from the rear surfaces of the plurality of terminal receiving chambers 5 of the connector housing 1 to the mounting position as shown in FIG. At a position before the mounting position of each terminal 6, the protruding locking portion 6b is retracted by the spring property to allow insertion of the terminal 6, and when each terminal 6 is inserted to the mounting position, as shown in FIG. The locking portion 6 of each terminal 6
b returns to the protruding position by the spring return property and is locked to the locked portion 1c of the connector housing 1. Next, among the terminals 6 adjacent to each other, between the terminals 6 that do not require electrical connection,
A portion of the carrier portion 8 located between the terminals 6 is cut using a carrier cutting jig device (not shown). Next, each of the electric wires W is connected to the electric wire pressing portion 6 of each terminal 6.
A process such as press contact with a is performed, and each electric wire W and each terminal 6 are connected. Next, the connecting surfaces 1a and 1b of both connector housings 1 are moved in a direction to approach each other, and the positioning of the housing lock projection 2 and the housing lock groove 3 is performed. When both alignments are performed, the connection surfaces 1a and 1b of both connector housings 1 further move in a direction of approaching each other, and when the connection surfaces 1a and 1b are joined, the housing is locked and FIG.
The connection is completed as shown in FIG. As the two connector housings 1 move to the connection position, the tab portions 6c of the terminals 6 of the lower connector housing 1 enter the tab insertion holes 10 of the upper connector housing 1, and FIG. In the connection position indicated by, the tab portion 6c of each terminal 6 of the lower connector housing 1 is brought into contact with the tab contact portion 6d of each terminal 6 of the upper connector housing 1. When it is not desired to electrically connect the upper and lower terminals 6 to each other, a bending process for bending the tab portion 6c is performed in advance. That is, this press-fit joint connector is
If necessary, it is possible to electrically connect the adjacent upper and lower terminals 6 and the adjacent left and right terminals 6. However, in the above-described conventional press-fit joint connector, the positioning of the terminal 6 in the terminal accommodating chamber 5 is performed by the locking portion 1c of the connector housing 1 and the locking portion of the terminal 6. 6b is locked, but the positional relationship between the locked portion 1c and the locking portion 6b must be configured with a margin due to component dimensional tolerances and the like. Specifically, as shown in FIG.
The distance d2 between the insertion end surface 6f of the terminal 6 and the locking portion 6b is set smaller than the distance d1 between the distal end surface 5a and the locked portion 1c. Accordingly, the terminal 6 can be displaced in the inserting direction and the opposite drawing direction, and the lower terminal 6 shifts to the right due to the external force from the electric wire W, or the upper terminal 6
Shifts to the left, the contact between the tab portion 6c and the tab contact portion 6d or the tab receiving portion 6e becomes a point contact as shown in FIG. 6 shifts to the left or the upper terminal 6 shifts to the right, the contact between the tab portion 6c and the tab contact portion 6d or the tab receiving portion 6e becomes a point contact as shown in FIG. If this is repeated, there is a problem that the tab portion 6c, the tab contact portion 6d, and the tab receiving portion 6e are deteriorated to cause poor contact. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and a press-fit joint connector in which poor contact between a tab portion and a tab contact portion does not occur even when a terminal is displaced in a terminal receiving chamber. The purpose is to provide. According to a first aspect of the present invention, there is provided a connector housing having a plurality of connector housings each having an upper surface and a lower surface as connecting surfaces, each of which has a plurality of terminals. A housing chamber is provided, and each terminal housing chamber has a terminal having a tab portion protruding toward one of the connection surfaces and a tab contact portion to which a tab portion inserted from the connection surface side opposite to the connection surface is in contact. The connector housings are accommodated, and the connector housings are connected in a multi-stage manner by moving the connecting surfaces of the two connector housings in a direction of approaching each other. In a press-fit joint connector in which a tab portion and a tab contact portion are in contact with each other, the tab portion has at least a terminal insertion / withdrawal direction of the terminal. An extended contact surface, the tab contact portion is configured to be elastically deformable in a direction perpendicular to a terminal insertion / drawing direction, and the tab contact portion is elastically deformed in a direction perpendicular to the terminal insertion / drawing direction to form the tab portion. While contacting the contact surface , Said
The tab is a base that extends in the direction perpendicular to the terminal insertion / extraction direction.
Part and the base, and extend in the terminal insertion / extraction direction.
And a contact portion having the contact surface.
An L-shaped tab insertion hole is formed in the bottom of the terminal.
Or the tab portion is in the terminal insertion / extraction direction.
A base extending in a direction orthogonal to the base, and fixed to one side of the base.
It has a contact surface that is fixed and extends in the terminal insertion / extraction direction.
It is fixed to the contact part and the other side of the base,
U-shaped from the contact part with the contact surface extending in the extension direction
And a U-shaped tab insertion port on the bottom of the terminal.
It is characterized by being formed . In this press-fit joint connector, when the two connector housings are connected to each other, the contact direction between the tab portion of one terminal and the tab contact portion of the other terminal becomes the direction of terminal insertion / insertion.
Because the direction is perpendicular to the drawing direction, for example, even if the terminal is displaced due to external force from the electric wire, the contact state of the tab and the tab contacting part only changes the position of the contact surface of the tab contacting the tab contacting part. Properly maintained. [0018] [0019] In addition, in this press-contact joint connector,
Strength as members of the tab portion can be improved. Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show a first embodiment of the present invention. FIG. 1A is a sectional view showing a connection state of both connector housings, and FIG. FIG. 2 is a sectional view showing a contact state between a tab portion and a tab contact portion of FIG.
2A is a perspective view around a tab contact portion, and FIG. 2B is a perspective view of a tab portion. In the first embodiment, the same components as those in the conventional example will not be described repeatedly, and description thereof will be omitted, and only different components will be described. The same components as in the conventional example are denoted by the same reference numerals in the drawings as in the conventional example. That is, in the first embodiment, FIG.
As shown in FIG. 2, the tab 6 c of the terminal 6 is formed by bending a flat plate at the center and forming one of the outer surfaces thereof as a contact surface 20 extending in the insertion direction / drawing direction S of the terminal 6. Have been. The tab contact portion 6d and the tab receiving portion 6e are
Each of the side portions on both sides of the terminal 6 is punched inward and bent. Tab contact part 6d
The base end is integrally connected to the side surface of the terminal 6, and the free end 21 extends in the terminal insertion / pull-out direction S. The free end 21 is configured to be displaceable by elastic deformation in a direction T orthogonal to the terminal insertion direction and the terminal extraction direction.
Both base ends of the tab receiving portion 6e are integrally connected to the side surface portion of the terminal 6, and the central surface portion 22 extends in the terminal insertion direction / drawing direction S. The lower end of the free end 21 of the tab 6c and the central surface 22 of the tab contact 6d is provided with a tapered surface 23 which is inclined in such a manner as to increase the distance between them as going downward. The tab portion 6c entering from below is smoothly moved by the two tapered surface portions 23 to the tab contact portion 6d.
And a tab receiving portion 6e. Further, a tab insertion port 24 is formed on the bottom surface of the terminal 6, and the tab insertion port 24 is located below the tab contact portion 6d and the tab receiving portion 6e. A tab insertion port 10 is provided in the connector housing 1 where the terminal 6 is in the mounting position and the tab insertion port 24 of the terminal 6 is located, as in the conventional example.
The shape and dimensions are such that the tab portion 6c of the first embodiment is inserted. In the above configuration, when the connecting surfaces 1a and 1b of both connector housings 1 are moved in a direction of approaching each other and the connecting surfaces 1a and 1b are joined, the housing is locked and as shown in FIG. The connection is completed. As the two connector housings 1 move to the connection position, the tab portions 6c of the terminals 6 of the lower connector housing 1 enter the tab insertion holes 10 and 24 of the upper connector housing 1 and the terminals 6, respectively. When the tab portion 6c comes into contact with the tab contact portion 6d and the tab receiving portion 6e, the tab contact portion 6d is displaced by elastic deformation in a direction T orthogonal to the terminal insertion direction and the pull-out direction, and the tab contact portion 6d of the tab portion 6c. And the tab receiving portion 6e are allowed to be inserted. And FIG.
In the connection position indicated by, the tab 6c of each terminal 6 of the lower connector housing 1 enters between the tab contact portion 6d and the tab receiving portion 6e of each terminal 6 of the upper connector housing 1, and the elasticity from the tab contact 6d. The tab portion 6c is brought into contact with the tab contact portion 6d and the tab receiving portion 6e by the force. For example, when an external force from the electric wire W is transmitted to the terminal 6, the terminal 6 slightly moves in the terminal insertion / withdrawal direction S in the terminal accommodating chamber 5 for the reason explained in the conventional example. Since the contact direction with the tab contact portion 6d is the orthogonal direction T of the terminal insertion / pull-out direction, even if the terminal 6 is displaced, only the contact position between the contact surface 20 of the tab portion 6c and the tab contact portion 6d is shifted. The contact state between the tab portion 6c and the tab contact portion 6d is properly maintained. Further, even if the tab 6c is inclined with respect to the vertical direction due to the displacement of the terminal 6, the contact position (including the contact angle) between the contact surface 20 of the tab 6c and the tab contact 6d is similarly shifted. Thus, the contact state between the tab portion 6c and the tab contact portion 6d is properly maintained. Therefore, a load acts on the tab portion 6c and the tab contact portion 6d or the tab receiving portion 6e due to the displacement of the terminal 6 as in the conventional example.
Since the tab 6c and the tab contact 6d or the tab receiving 6e do not come into a point contact state, the tab 6c, the tab contact 6d, and the tab receiving 6e are not deteriorated, and poor contact is prevented. 3 to 5 show a second embodiment of the present invention. FIG. 3 is a partial perspective view of the terminal, FIG. 4 is a partial bottom view of the terminal, and FIGS. It is a perspective view which shows the contact state of the tab part inclined with respect to the perpendicular direction, and a tab contact part. In the second embodiment, the same components as those in the first embodiment will not be described repeatedly, and description thereof will be omitted, and only different components will be described. The same components as those in the first embodiment are denoted by the same reference numerals in the drawings as in the conventional example. That is, in the second embodiment, FIG.
As shown in FIG. 4 and FIG. 4, the tab 6c of the terminal 6 includes a base 25 extending in a direction T orthogonal to the terminal insertion / extraction direction, and a contact surface 20 fixed to the base 25 and extending in the terminal insertion / extraction direction S. The contact portion 26 has an L-shape. The tab contact portion 6 d has a lower end integrally connected to the side surface of the terminal 6 and an upper end as a free end 21. An L-shaped tab insertion port 24 is formed on the bottom surface of the terminal 6. The second embodiment has the same operation and effect as the first embodiment, and as shown in FIGS. 5A and 5B, the tab portion is displaced due to the displacement of the terminal 6 or the like. 6
Even if c is inclined with respect to the vertical direction, the contact surface 20 of the tab portion 6c
The contact state between the tab 6c and the tab contact 6d is properly maintained only by shifting the contact position (including the contact angle) between the tab 6c and the tab contact 6d. In the second embodiment, the tab portion 6c
Are L-shaped, and the strength of the tab portion 6c as a member is high and excellent in durability and the like. Further, since the strength of the tab portion 6c is high, the contact between the tab portion 6c and the tab contact portion 6d can be sufficiently ensured without providing the tab receiving portion. The contact with the contact portion 6d is assured and stable. FIG. 6 shows a third embodiment of the present invention.
FIG. 3 is a perspective view of a tab portion of the terminal. The third embodiment is different from the second embodiment only in the configuration of the tab portion and the tab insertion opening, and the other configurations are the same as those of the second embodiment. The description thereof will be omitted, and only different components will be described. That is, in the third embodiment, the tab portion 6c is fixed to one side of the base portion 25 extending in the direction T orthogonal to the terminal insertion / drawing direction. A contact portion 26 having a contact surface 20 extending in the drawing direction S and a contact portion 27 fixed to the other side of the base 25 and having a contact surface extending in the terminal insertion / drawing direction S are formed in a U-shape. I have. Also, on the bottom of the terminal 6,
The U-shaped tab insertion port 24 is formed as the deficient area is added by a virtual line in FIG. In the third embodiment, the same functions and effects as those of the first embodiment can be obtained, and as in the second embodiment, the tab portion 6c has a high strength as a member and is excellent in durability and the like. I have. In addition, if a tab contact portion is provided which also contacts the other contact portion 27, the reliability of the electrical connection is increased by making contact at two places. As described above, according to the first aspect of the present invention, the tab portion has at least a contact surface extending in the terminal insertion / extraction direction of the terminal, and the tab contact portion is connected to the terminal. Since the tab contact portion is configured to be elastically deformable in a direction perpendicular to the insertion / drawing direction and the tab contact portion is configured to be elastically deformed in the direction perpendicular to the terminal insertion / drawing direction to contact the contact surface of the tab portion, both connectors are provided. When the housing is connected,
Since the contact direction between the tab portion of one terminal and the tab contact portion of the other terminal is orthogonal to the terminal insertion / extraction direction, the tab contact portion contacts even if the terminal is displaced due to, for example, an external force from an electric wire. Just by shifting the position of the contact surface of the tab portion, the contact state between the tab portion and the tab contact portion is properly maintained, and poor contact between the tab portion and the tab contact portion does not occur. Further, the tab portion is fixed to the base portion extending in a direction orthogonal to the terminal insertion / drawing direction, and the base portion,
Since being composed of a contact portion having a contact surface extending into the terminal insertion and withdrawal direction, improves the strength of the members of the tab portion, it is excellent in durability.
