Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly to a connector in which contacts are doubly locked in an insulating housing.

[0002]

2. Description of the Related Art As a connector which double-locks contacts in an insulating housing to increase the locking strength of the contacts to the insulating housing, for example, Japanese Patent Publication No.
There are those disclosed in Japanese Patent No. 23391 and Japanese Patent Laid-Open No. 4-137474.

That is, the connector disclosed in Japanese Patent Publication No. 4-23391 and Japanese Patent Laid-Open No. 4-137474 discloses an insulating housing having a plurality of contacts and a plurality of contact accommodating chambers for receiving the contacts, respectively. The double locking member is inserted from the side wall of the insulating housing.

Further, another type of connector has an insulating housing having a contact accommodating chamber for accommodating a plurality of contacts, and a double locking member inserted from the rear wall side of the housing. In some cases, the upper surface of the double locking member is exposed at the free end so that the double locking member cannot slide when the terminal is incompletely inserted. And
In this state, the lock lever does not bend and the mating connector cannot be fitted to detect the incompletely inserted state of the contact.

[0005]

[Problems to be Solved by the Invention] However, Japanese Patent Publication No. 4-2
Since the connectors disclosed in Japanese Patent No. 3391 and Japanese Patent Laid-Open No. 4-137474 have a structure in which the double locking member is inserted from the side wall of the insulating housing, when the double locking member is in the temporary locking state, The side wall of the insulating housing into which the double locking member is inserted protrudes from the surface. For this reason, there is a drawback in that the main locking state is likely to occur during transportation or when an unexpected external force is applied. Further, since such a double locking member is simply inserted from the side wall of the insulating housing, it may fall off from the insulating housing as opposed to the above-mentioned full locking state.

Further, in a connector of the type in which the double locking member is attached to the rear surface of the insulating housing, if the cable with the contacts crimped in the final locking state is pressed, the temporary locking state is restored. Also, a double locking member is inserted at the rear end of the barrel part of the contact to double lock the contact, but the contact is stretched due to the crimping of the cable, which causes the double locking position of the contact to fluctuate. May occur, and a state in which the double locking is not performed may occur. Furthermore, in this type of connector, the double locking member cannot slide when the terminal is half-inserted, and since the upper surface of the double locking member projects below the lock lever, the lock lever does not bend. Rejects mating with the mating connector. That is, this type of connector only detects the half-inserted state of the contact.

The present invention has been proposed in view of the above-mentioned drawbacks of the prior art, and prevents the double locking member from being permanently locked or disengaged at the time of transportation and by an unexpected external force. It is also an object of the present invention to provide a double locking type connector that prevents the locking from returning to the temporary locking state even if the cable is twisted, and does not change the double locking position of the contact. .

[0008]

DISCLOSURE OF THE INVENTION The present invention provides a connector for doubly locking contacts loaded in an insulating housing, the insulating housing having a plurality of contacts and a contact receiving chamber for receiving the contacts. The contact includes a double locking member that is inserted into the insulating housing and a pressing member that holds the double locking member in the insulating housing. A first locking portion that engages with a lance formed in the insulating housing, and a second locking portion that engages with a predetermined portion of the double locking member only at the time of main locking, The double locking member is housed in the insulating housing so as to be movable between a temporary locking position and a main locking position in a direction intersecting with the contact, and the double locking member is temporarily locked. When in the locking position, the contour It is configured such that the contact can be inserted / removed, and in the main locking position, both contacts of the contact are engaged to double-lock and hold the contact in the insulating housing. .

Further, according to the present invention, the double locking member is moved from the temporary locking position to the main locking position by pressing the acupressure surface formed on the upper surface of the double locking member. It is characterized in that the acupressure surface is lower than the upper surface of the lock lever formed in the insulating housing.

Also, the present invention provides a connector for double locking a contact loaded in an insulating housing,
An insulating housing having a plurality of contacts, a contact accommodating chamber that receives the contacts, a double locking member that is inserted into the insulating housing, and a holding member that holds the double locking member in the insulating housing. Have
The contact is provided with a first locking portion that engages with a lance formed in the insulating housing at the time of temporary locking and full locking, and a predetermined double locking member is provided only at the time of main locking. A second locking portion that engages with the part is formed, and the double locking member is movable in a direction intersecting with the contact and between a temporary locking position and a main locking position. The contact is inserted and removed when the double locking member is in the temporary locking position and is engaged with the locking portion of the contact in the main locking position. Is double retained in the insulating housing, and the double locking member moves from the temporary locking position to the final locking position in the insulating housing located above the double locking member. The double locking portion is provided so as to be performed by bending of the lock lever provided. And sets the positional relationship between the lock lever and.

[0011]

According to the present invention having the above-mentioned structure, the double locking member is held and housed in the insulating housing by the pressing member so as to be movable only from the temporary locking position to the main locking position. The double locking member does not separate from the insulating housing.

The double locking member is moved from the temporary locking position to the main locking position by pressing the acupressure surface formed on the upper surface of the double locking member, and Since the acupressure surface is configured to be lower than the upper surface of the lock lever formed in the insulating housing, the double locking member is provided by the presence of the lock lever due to the presence of the lock lever during transportation or even when an unexpected external force is applied to the connector. Since the external force is prevented from being applied, the double locking member does not easily move from the temporary locking position to the main locking position.

Similarly, in the case where the double locking member is moved from the temporary locking position to the main locking position by the bending of the lock lever provided at a predetermined position of the insulating housing, the double locking member is also used. Since the heavy locking member is covered by the upper lock lever, the double locking member is prevented from moving from the temporary locking position to the full locking position due to an unexpected external force. In addition, when the contact is half-inserted, the double locking member cannot move to the full locking position, which limits the flexure of the lock lever that presses the double locking member, and connects with the mating connector. Be rejected.

The double locking member 2 housed in the space 18 inside the insulating housing 1 has an upper plate portion 20a and a lower plate portion 20b which are spaced apart and face each other in parallel.
A partition wall is integrally provided between a and the lower plate portion 20b at a predetermined interval, and the partition wall forms a contact insertion hole 21. The contact insertion hole 21 communicates with the contact housing chamber 11 on the upper stage of the insulating housing 1.

On the upper plate portion 20a of the double locking member 2, two finger-pressure portions 22 are formed so as to be inserted between the notch portion of the frame-shaped thick portion 10 of the housing 1 and the finger-pressure portion 13 of the lock lever 12. ing. A protrusion 23 is formed in the horizontal direction on the outer side of the acupressure part 22. Grooves 24a and 24b are formed on the upper and lower sides of the protrusion 23, respectively.
24b engages with an engagement protrusion 10a formed on the end surface of the cutout portion of the frame-shaped thick portion 10 of the insulating housing 1. That is, the lower groove 24a engages with the engaging projection 10a when the double locking member 2 is in the temporary locking position, and serves as a temporary locking groove.
The upper groove 24b engages with the engaging projection 10a when the double locking member 2 is in the lowered position, that is, when the double locking member 2 is in the main locking position, and is a main locking groove.

Next, after the double locking member 2 is loaded into the space 18 of the insulating housing 1, the space 1 of the double locking member 2 is loaded.
The holding member 3 for preventing the escape from the inside 8 is loaded in the space 19 in the insulating housing 1. The lower side of the pressing member 3 is integrally joined to the lower end of the insulating housing 1 via the hinge portion 16, and the pressing member 3 is lifted in the direction indicated by the arrow around the hinge portion 16 to form the pressing member 3.

Further, in the second embodiment, as will be described later, even when the double locking member 2 is moved from the temporary locking position to the main locking position by pressing the finger pressure portion 13 of the lock lever 12. It is used.

A contact accommodating chamber 11 for accommodating each contact 4 by partitioning it is formed inside the insulating housing 1. Also in this second embodiment, the contact accommodating chamber 11 has two upper and lower stages, and each stage has 11 stages.
Individual contact storage chambers 11 are formed.

The rear side end of the upper contact accommodating chamber 11 is located on the inner side so as to accommodate a double locking member 2 described later, and forms a space 18.
A double locking member 2 which will be described later is placed on a partition wall that partitions the lower contact accommodating chamber 11.

Further, the rear end of the partition wall for partitioning the lower contact accommodating chamber 11 is retracted to the inside by an amount for accommodating the pressing member 3 described later to form a space 19 for accommodating the pressing member 3. There is.

On the inner surface side and the rear end side of the frame-shaped thick portion 10 of the insulating housing 1, as in the first embodiment,
An engagement window 10b is formed in which the engagement projections 35 and 36 of the pressing member 3 described later are engaged. The engagement windows 10b are also provided so as to form a pair on the left and right, but since this is a perspective view, only the left side is visible and the right side is hidden.

The double locking member 2 housed in the space 18 inside the insulating housing 1 has an upper plate portion 20a and a lower plate portion 20b which are spaced apart and face each other in parallel. A partition wall is integrally provided at a predetermined distance from the plate portion 20b, and the partition wall forms a contact insertion hole 21. This contact insertion hole 21

The upper plate portion 20a of the double locking member 2 is flush with the first embodiment, unlike the first embodiment. The upper surface of the flat upper plate portion 20a is pressed by the finger pressure portion 13 of the lock lever 12 to move the double locking member 2 downward to the full locking position, as described later.

On the insertion side end surface of the double locking member 2, locking recesses 25a and 25b are formed, which are not shown in FIGS. 5 and 6, but can be seen from FIG. 7 which will be described later. The locking recesses 25 a and 25 b of the above engage with the engaging projections 14 formed in the insulating housing 1. That is, the lower locking recess 25a engages with the engaging projection 14 when the double locking member 2 is in the temporary locking position, and serves as the temporary locking recess 25a, and the upper recess 25b double locks. When the member 2 is lowered, the main locking is correspondingly performed, and the main locking recess 25b is formed.

Next, after loading the double locking member 2 in the space 18 of the insulating housing 1, the space 1 of the double locking member 2 is loaded.
The holding member 3 for preventing the escape from the inside 8 is loaded in the space 19 in the insulating housing 1. The lower side of the pressing member 3 is integrally joined to the lower end of the insulating housing 1 via the hinge portion 16, and the pressing member 3 is lifted in the direction indicated by the arrow around the hinge portion 16 to form the pressing member 3. The engaged protrusions 35 and 36 engage with the locking windows 10b formed in the corresponding insulating housing 1. The pressing member 3 is also formed with a grid of contact insertion holes 31 that communicate with the lower contact housing chamber 11 of the insulating housing 1 and the contact insertion hole 21 of the upper double locking member 2.

Although not shown in the figure, the contact 4 has a first locking portion 41 that engages with a lance formed inside the insulating housing 1, and a second locking portion 41 that engages with the double locking member 2.
Is provided with the locking portion 43.

The contact 4 is inserted into the contact accommodating chamber 11 in the insulating housing 1 from the contact insertion hole 31 of the pressing member 3 on the rear surface side. When the contact 4 is inserted while the double locking member 2 is in the temporary locking state, the lance 15 formed inside the insulating housing 1 causes the first locking portion 41 of the contact 4, as shown in FIG. The upper plate portion 20a and the lower plate portion 20 of the double locking member 2
The lower edge portion of b is not engaged with the second locking portion 43. That is, in this state, the contact 4 can be inserted and removed, and the engagement protrusion 14 is engaged with the temporary engagement recess 25 a on the lower side of the double engagement member 2.

In the case of the final locking, as shown in FIG. 8, the finger pressure portion 13 of the lock lever 12 provided flexibly on the upper surface of the insulating housing 1 is pressed with a finger. Then, the acupressure part 13 of the lock lever 12 descends and presses the upper plate part 20a of the double locking member 2. As a result, the double locking member 2 is lowered, and the upper plate portion 20a and the lower plate portion 20 are
The edge portion of b is engaged with the side surface of the second locking portion 43 of the contact 4. When the double locking member 2 is moved to the main locking position, the engagement protrusion 14 provided inside the insulating housing 1 engages with the main locking recess 25b of the double locking member 2, and The movement (elevation) of the locking member 2 afterward is prevented.

Even in the second embodiment, as in the first embodiment, when even one of the contacts 4 is in the half-inserted state, the upper plate portion 20a or the lower portion of the double locking member 2 is lowered. The lower surface of the plate portion 20b contacts the upper surface of the second locking portion 43 of the contact 4 and prevents the double locking member 2 from moving to the main locking position. Therefore, when trying to connect with the mating connector in the half-inserted state, the lock lever 12 is locked by the double locking member 2.
This prevents the connector from bending and rejects the connection with the mating connector. Therefore, it is possible to easily detect that even one contact 4 is half-inserted, and the connector is not connected when the contact is incompletely inserted.

In the above description, the mooring of the double locking member 2 at the temporary locking position and the final locking position is performed by the engagement projection 14 formed inside the insulating housing 1 and the double locking member 2. Locking recess 25 formed on the insertion side end surface of the upper plate 20a
However, the present invention is not limited to this, and the engaging projections and the engaging grooves are provided in other portions and are engaged with each other. Therefore, the double locking member 2 may be moored at the temporary locking position and the main locking position, respectively.

Also, in the second embodiment, the pressing member 3 has been described as being integrally attached to the insulating housing 1 by the hinge portion 16, but the pressing member 3 is separated from the insulating housing 1. It may be.

Also in the second embodiment, the contact accommodating chambers 11 formed inside the insulating housing 1 are arranged in two stages, that is, the upper and lower stages. However, similar to the first embodiment, The contact accommodating chambers 11 may be provided in one stage, three stages or more, and may be arranged in a staggered manner.

Further, also in the second embodiment, the double locking position of the contact 4, that is, the first and second locking portions 4 is used.
The positions of 1, 43 are not limited to those shown in the figure.

[0054]

As described above, according to the present invention, the double locking member can be moved only from the temporary locking position to the main locking position, and cannot be removed from the insulating housing by the pressing member. Since it is held and accommodated as described above, the double locking member does not come off from the insulating housing.

Further, the double locking member is moved from the temporary locking position to the main locking position by pressing the acupressure surface formed on the upper surface of the double locking member. Moreover, when the acupressure surface is configured to be lower than the upper surface of the lock lever formed in the insulating housing, during transportation and even when an unexpected external force is applied to the connector,
The presence of the lock lever prevents external force from being applied to the double locking member, and the double locking member does not easily move from the temporary locking position to the main locking position.

Similarly, even when the double locking member is moved from the temporary locking position to the final locking position by the bending of the lock lever provided at a predetermined position of the insulating housing, Since the double locking member moored in the temporary locking position is covered by the upper lock lever, even if an unexpected external force is applied to the connector, the double locking member in the temporary locking position is temporarily locked. It does not move from the locked position to the main locked position.

In addition, in these connectors, the double locking member cannot move to the main locking position when the contact is half inserted into the insulating housing. Incomplete insertion of contacts can be reliably detected.

Further, even when the double locking member is moved from the temporary locking position to the final locking position by the bending of the lock lever for locking the connection with the mating connector,
If the contact is half-inserted (incomplete insertion), the lock lever is also restricted from bending when connected to the mating connector, so if the contact is imperfectly inserted, the connection with the mating connector is rejected. It will not happen that the connector is not connected properly.
