Description

The present invention relates to a connector structure.

Conventionally, when the terminal accommodated in the terminal accommodating chamber of the housing is in the normal accommodating position, the lance receiving hole provided in the terminal and the lance provided in the housing are engaged with each other, and a spacer is provided in the housing. A connector structure having a so-called double locking structure in which a spacer and a terminal are engaged by being housed in a normal insertion position of a spacer insertion hole is widely known (see, for example, Patent Document 1). According to the double locking structure, it is possible to extremely surely prevent the terminal accommodated in the terminal accommodating chamber from moving from the normal accommodating position in the exit direction (rear side in the insertion direction).

In the connector structure described in the above document, a terminal for a coaxial wire having a columnar shape connected to an end portion of the coaxial wire is used as the terminal. Therefore, the position of the lance receiving hole and the lance may be displaced due to the rotation of the terminal around the axis in the terminal accommodating chamber. In order to prevent this misalignment, a protrusion (also called a stabilizer) is provided on the side surface of the terminal, a groove is provided in the terminal accommodating chamber along the insertion direction of the terminal, and the groove is provided when the terminal is inserted into the terminal accommodating chamber. It is designed to guide the protrusion. Furthermore, when the terminal is in the normal accommodation position, the protrusion located on the front side in the insertion direction from the spacer insertion hole (spacer) and the spacer engage in the insertion direction to prevent the terminal from moving in the disconnection direction. It is supposed to be done.

By the way, in such a connector structure, it is important to be able to easily detect whether or not the terminal accommodated in the terminal accommodating chamber is in the normal accommodating position. In this regard, in the connector structure described in the above document, when the terminal is not in the normal insertion position and the protrusion is located in the spacer insertion hole, the protrusion interferes with the spacer and the spacer cannot be accommodated in the normal insertion position. Therefore, it is possible to detect that the terminal is not in the normal accommodation position. However, when the terminal is not in the normal accommodation position and the protrusion is located on the rear side in the insertion direction from the spacer insertion hole, the spacer can be accommodated in the normal insertion position without the protrusion interfering with the spacer. Therefore, there is a problem that it cannot be detected that the terminal is not in the normal accommodation position.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a connector structure capable of reliably detecting whether or not a terminal accommodated in a terminal accommodating chamber is in a normal accommodating position. be.

In order to achieve the above-mentioned object, the connector structure according to the present invention is characterized by the following (1) and (2).
(1)
A terminal having a columnar shape having a protrusion and a lance receiving hole on the side surface,
A terminal accommodating chamber for accommodating the terminal, a lance provided so as to face the terminal accommodating chamber and capable of engaging with the lance receiving hole when the terminal is in the normal accommodating position, and the terminal accommodating chamber as the terminal. A housing provided with a spacer insertion hole provided to divide in the insertion direction of the
When the terminal is in the normal accommodation position, the spacer is accommodated in the normal insertion position of the spacer insertion hole and can engage with the protrusion in the insertion direction.
It is a connector structure equipped with
The housing accommodates the terminal from a position on the rear side in the insertion direction from the spacer insertion hole to a position on the front side in the insertion direction from the spacer insertion hole so as to straddle the spacer insertion hole along the insertion direction. An opening provided in the chamber, provided with an opening for guiding the protrusion when the terminal is inserted into the terminal accommodating chamber.
When the terminal is in the normal accommodation position of the terminal accommodation chamber, the protrusion is located on the front side in the insertion direction from the spacer insertion hole in the opening, and the protrusion does not interfere with the spacer. The spacer can be accommodated in the normal insertion position,
When the terminal is not in the normal accommodation position of the terminal accommodation chamber, the protrusion is located on the rear side of the spacer insertion hole in the opening in the insertion direction, or the protrusion interferes with the spacer. The spacer cannot be accommodated in the normal insertion position,
It has a connector structure configured as such.
(2) In the connector structure described in (1) above,
The housing has a plurality of the terminal accommodating chambers.
Must have a connector structure.

According to the connector structure having the configuration of (1) above, when a terminal having a columnar shape is inserted into the terminal accommodation chamber, a protrusion provided on the side surface of the terminal is guided to an opening provided in the terminal accommodation chamber. This prevents the position of the lance receiving hole and the lance from being displaced due to the rotation of the terminal around the axis in the terminal accommodating chamber. Here, the opening means an opening that communicates between the terminal accommodating room and the outside of the housing and is exposed to the outside of the housing.

When the terminal is in the normal accommodation position of the terminal accommodation chamber, the protrusion is located on the front side in the insertion direction from the spacer insertion hole in the opening, so that the protrusion does not interfere with the spacer. Therefore, the spacer can be accommodated in the normal insertion position of the spacer insertion hole. Therefore, when the terminal is in the normal accommodation position, the lance receiving hole provided in the terminal and the lance provided in the housing are engaged with each other, and the protrusion provided on the side surface of the terminal is in the normal insertion position. The so-called double locking structure is achieved by engaging with the housed spacer.

When the terminal is not in the normal accommodation position of the terminal accommodation chamber and the protrusion is located in the spacer insertion hole, the protrusion interferes with the spacer and the spacer cannot be accommodated in the normal insertion position, so that the terminal cannot be accommodated. Can be detected that is not in the normal accommodation position.

Further, when the terminal is not in the normal accommodation position of the terminal accommodation chamber and the protrusion is located on the rear side in the insertion direction from the spacer insertion hole in the opening, the protrusion exposed from the opening inserts the spacer in the opening. By visually or by detecting from the outside of the housing that it is behind the hole in the insertion direction by visual inspection or detection equipment (electrical inspection with a conduction pin, optical inspection with a camera, etc.), the terminal can be placed in the normal accommodation position. It can be detected that there is no such thing.

According to the connector structure having the configuration of (2) above, the positions of the protrusions exposed from the openings can be visually confirmed in all of the plurality of terminal accommodating chambers. For this reason, in particular, when the terminal should be accommodated only in a part of the terminal accommodating chambers among the plurality of terminal accommodating chambers due to the mode of the mating connector side, any of the terminal accommodating chambers is accommodated. By confirming whether or not the protrusion is exposed from the opening of the chamber, it is possible to confirm from the outside of the housing whether or not the terminal is accommodated in the terminal accommodating chamber in which the terminal should be accommodated.

According to the present invention, it is possible to provide a connector structure capable of reliably detecting whether or not a terminal accommodated in a terminal accommodating chamber is in a normal accommodating position.

The present invention has been briefly described above. Further, the details of the present invention will be further clarified by reading through the embodiments described below (hereinafter referred to as "embodiments") with reference to the accompanying drawings.

<Embodiment>
Hereinafter, the connector structure 1 according to the embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 5, the connector structure 1 according to the embodiment of the present invention includes a terminal 10 connected to a terminal of a coaxial wire 40, a housing 20 accommodating the terminal 10, and a spacer attached to the housing 20. 30 and. Hereinafter, for convenience of explanation, in the insertion direction of the terminal 10 with respect to the housing 20 (hereinafter, may be simply referred to as “insertion direction”), the side (left side in FIG. 1) to which the mating side connector (not shown) is fitted is forward. The side is called the side, and the opposite side (right side in FIG. 1) is called the rear side. Hereinafter, each component constituting the connector structure 1 will be described in order.

First, the terminal 10 will be described. As shown in FIGS. 2 and 4B, the metal terminal 10 is a terminal connected to the terminal of the coaxial line 40, and generally has a columnar shape. The terminal 10 typically contains an inner conductor terminal (female terminal) connected to the inner conductor (linear conductor) of the coaxial wire 40, a dielectric accommodating the inner conductor terminal, and a dielectric. It is composed of an outer conductor terminal connected to an outer conductor (braid) of the coaxial wire 40 (not shown). The appearance of the cylindrical terminal 10 shown in FIG. 2 and the like is, more accurately, the appearance of the outer conductor terminal constituting the terminal 10.

As shown in FIG. 2A, on one side of the side surface of the cylindrical terminal 10 at a position closer to the front than the center in the insertion direction, a rectangular plate-shaped protrusion (stabilizer) protruding radially outward from the same side surface. 11 is provided integrally. When the terminal 10 is inserted into the housing 20, the stabilizer 11 is guided into the opening 24 (see FIG. 3C, etc.) provided in the terminal accommodating chamber 21 described later in the housing 20, so that the stabilizer 11 is inside the terminal accommodating chamber 21. It has a function of suppressing the rotation of the terminal 10 around the axis at.

As shown in FIG. 2B, a lance is placed on one side (the side on which the stabilizer 11 is provided) of the terminal 10 near the front end in the insertion direction (position on the front side of the stabilizer 11) and on the other side, as shown in FIG. 2 (b). A receiving hole 12 is provided. When the terminal 10 is inserted into the housing 20, the lance receiving hole 12 engages with the lance 22 (see FIG. 4B) provided in the housing 20 so that the terminal 10 can be pulled out in the disconnection direction (rear side). It has a function to suppress movement. As shown in FIG. 3, the terminal 10 is inserted into the housing 20 with the stabilizer 11 located at the bottom and the lance receiving hole 12 at the top.

Next, the housing 20 will be described. As shown in FIGS. 1 and 3-5, the resin housing 20 generally has a rectangular parallelepiped shape extending in the insertion direction. Inside the housing 20, a plurality of terminal accommodating chambers 21 accommodating a plurality of (two in this example) terminals 10 are formed through along the insertion direction so as to be arranged in the width direction (particularly). , See Figure 4-5).

As shown in FIGS. 4 (b) and 5 (b), a cantilever-shaped lance 22 is integrally provided inside the housing 20 so as to face the upper position near the front end of the terminal accommodating chamber 21. Has been done. As described above, the lance 22 has a function of suppressing the movement of the terminal 10 in the disconnection direction (rear side) by engaging with the lance receiving hole 12 of the terminal 10 when the terminal 10 is inserted into the housing 20. Have.

Inside the housing 20, as shown in FIGS. 1 and 3-5, a plurality of terminal accommodating chambers 21 are divided in the insertion direction and in the width direction on the rear side from the position where the lance 22 is provided. A spacer insertion hole 23 is provided so as to open downward over the entire area. As will be described later, the spacer insertion hole 23 has a function of suppressing the movement of the terminal 10 in the exit direction (rear side) by inserting the spacer 30.

On the lower surface of the housing 20, as shown in FIGS. An opening (slit) 24 extending from the insertion hole 23 to a position on the front side is provided in the terminal accommodating chamber 21. The opening 24 communicates with the inside of the terminal accommodating chamber 21 and the outside of the housing 20, and is exposed to the outside of the housing 20.

The width dimension of the opening 24 is slightly larger than the width dimension of the stabilizer 11 so that the stabilizer 11 of the terminal 10 can enter the opening 24 when the terminal 10 is inserted into the terminal accommodating chamber 21. As described above, the opening 24 guides the stabilizer 11 of the terminal 10 that has entered the opening 24 when the terminal 10 is inserted into the terminal accommodating chamber 21, so that the opening 24 rotates around the axis of the terminal 10 in the terminal accommodating chamber 21. It has a function of suppressing rotation.

In the terminal 10 inserted into the terminal accommodating chamber 21, the stabilizer 11 of the terminal 10 that has entered the opening 24 has the front end of the opening 24 (that is, the front end of the portion of the opening 24 that is in front of the spacer insertion hole 23). It can be inserted up to the position where it comes into contact with the portion) (see FIG. 4 (b)). This position corresponds to the "normal accommodation position".

Next, the spacer 30 will be described. As shown in FIGS. The spacer 30 is attached to the housing 20 by inserting it into the spacer insertion hole 23 of the housing 20 from below to above.

When the spacer 30 is inserted into the spacer insertion hole 23, the spacer 30 is provided with a locking mechanism (not shown) provided at a position where the pair of side plate portions 32 of the spacer 30 and the pair of side walls of the housing 20 rub against each other. It is possible to lock the spacer insertion hole 23 at the temporary locking position and the main locking position. This locking position is a position where the spacer 30 is inserted all the way to the innermost part (up to the upper side) of the spacer insertion hole 23. This position corresponds to the "normal insertion position". The temporary locking position is a position slightly downward from the main locking position.

In the state where the spacer 30 is locked in the temporary locking position, the stabilizer 11 of the terminal 10 does not interfere with the bottom plate portion 31 of the spacer 30 when the terminal 10 is inserted into the terminal accommodating chamber 21 (the space above the bottom plate portion 31). Can pass through). Therefore, the terminal 10 can be inserted from the insertion start position to the normal accommodation position.

On the other hand, in the state where the spacer 30 is locked at the main locking position, the stabilizer 11 of the terminal 10 interferes with the bottom plate portion 31 of the spacer 30. In other words, when the stabilizer 11 is located in the spacer insertion hole 23 in the insertion direction, the spacer 30 cannot move from the temporary locking position to the main locking position, while the stabilizer 11 has the spacer insertion hole in the insertion direction. When it is located on the front side or the rear side of 23, it can move from the temporary locking position to the main locking position. The components constituting the connector structure 1 have been described above.

Next, a procedure for accommodating the terminal 10 in the normal accommodating position of the terminal accommodating chamber 21 of the housing 20 will be described. First, as shown in FIG. 3, in a state where the spacer 30 is temporarily locked to the housing 20, the terminal 10 is oriented so that the stabilizer 11 is located below and the lance receiving hole 12 is located above. Then, the housing 20 is moved from the rear position to the front side and inserted into the terminal accommodating chamber 21.

As a result, the stabilizer 11 starts to enter the opening 24 on the rear side of the spacer insertion hole 23, and the opening 24 guides the stabilizer 11 to the front side. In this way, while the stabilizer 11 is guided forward by the opening 24 on the rear side of the spacer insertion hole 23, the terminal 10 is further inserted deeper (toward the front side), and the stabilizer 11 inserts the spacer insertion hole 23. It enters the opening 24 on the front side of the spacer insertion hole 23 and abuts on the front end portion of the opening 24 (see FIG. 4B). That is, the terminal 10 reaches the normal accommodation position. When the terminal 10 reaches the normal accommodation position, the lance 22 of the housing 20 and the lance receiving hole 12 of the terminal 10 engage with each other (see FIG. 4B).

After the terminal 10 reaches the normal accommodation position, the spacer 30 is moved from the temporary locking position to the main locking position, and the spacer 30 is accommodated in the main locking position. When the terminal 10 reaches the normal accommodation position, as shown in FIGS. 4 (b) and 4 (c), the stabilizer 11 is located on the front side of the spacer insertion hole 23, so that the spacer 30 is temporarily locked. It is in a state where it can be moved from to the main locking position. When the spacer 30 moves from the temporary locking position to the main locking position while the terminal 10 is in the normal accommodation position, the rear end surface of the stabilizer 11 and the front end surface of the bottom plate portion 31 of the spacer 30 are engaged in the insertion direction. It will fit.

As described above, when the terminal 10 is in the normal accommodation position and the spacer 30 is accommodated in the main locking position, as shown in FIG. 4B, the lance 22 of the housing 20 and the lance receiver of the terminal 10 are received. The so-called double locking structure is achieved by the engagement with the hole 12 and the engagement between the stabilizer 11 of the terminal 10 and the spacer 30. Therefore, it is possible to extremely surely prevent the terminal 10 from moving from the normal accommodation position in the exit direction (rear side).

Next, in the connector structure 1, a method for detecting whether or not the terminal 10 accommodated in the terminal accommodating chamber 21 is in the normal accommodating position will be described.

As described above, in the state where the terminal 10 is in the normal accommodation position, the stabilizer 11 of the terminal 10 is located on the front side of the spacer insertion hole 23, and the spacer 30 can be accommodated in the main locking position. (See FIG. 4 (b)). Therefore, it can be visually confirmed from the outside of the housing 20 that the stabilizer 11 exposed from the opening 24 is on the front side of the spacer insertion hole 23 in the opening 24 and the spacer 30 is housed in the main locking position. By detecting with a detection device (electrical inspection by a continuity pin or the like, optical inspection by a camera or the like, etc.), it is possible to detect that the terminal 10 is in the normal accommodation position.

On the other hand, when the terminal 10 is not in the normal accommodation position, the stabilizer 11 is located in the spacer insertion hole 23 in the insertion direction, and the stabilizer 11 is located behind the spacer insertion hole 23 in the opening 24. It can be assumed.

When the terminal 10 is not in the normal accommodation position and the stabilizer 11 is located in the spacer insertion hole 23 in the insertion direction, the stabilizer 11 interferes with the spacer 30 as described above, so that the spacer 30 is temporarily locked. Cannot move to the main locking position. Therefore, the terminal 10 is not in the normal accommodation position by visually detecting that the spacer 30 is not in the main locking position or by detecting by a detection device (electrical inspection by a conduction pin or the like, optical inspection by a camera or the like, etc.). Can be detected.

When the terminal 10 is not in the normal accommodation position and the stabilizer 11 is located behind the spacer insertion hole 23 in the opening 24, the spacer 30 moves from the temporary locking position to the main locking position as shown in FIG. Therefore, the spacer 30 can be accommodated in the main locking position. However, it is detected by visual inspection or a detection device (electrical inspection by a conduction pin or the like, optical inspection by a camera or the like, etc.) that the stabilizer 11 exposed from the opening 24 is behind the spacer insertion hole 23 in the opening 24. By doing so, it is possible to detect that the terminal 10 is not in the normal accommodation position.

As described above, according to the connector structure 1 according to the embodiment of the present invention, when the terminal 10 having a columnar shape is inserted into the terminal accommodation chamber 21, the stabilizer 11 provided on the side surface of the terminal 10 is the terminal accommodation chamber 21. By being guided by the opening 24 provided in the terminal accommodation chamber 21, the positional deviation between the lance receiving hole 12 and the lance 22 due to the rotation of the terminal 10 around the axis in the terminal accommodating chamber 21 is prevented.

When the terminal 10 is in the normal accommodation position of the terminal accommodation chamber 21, the stabilizer 11 is located on the front side of the spacer insertion hole 23 in the opening 24, so that the stabilizer 11 does not interfere with the spacer 30. Therefore, the spacer 30 can be accommodated in the normal insertion position of the spacer insertion hole 23. Therefore, when the terminal 10 is in the normal accommodation position, the lance receiving hole 12 provided in the terminal 10 and the lance 22 provided in the housing 20 are engaged with each other, and the stabilizer provided on the side surface of the terminal 10. The so-called double locking structure is achieved by engaging the spacer 30 housed in the normal insertion position with 11.

When the terminal 10 is not in the normal accommodation position of the terminal accommodation chamber 21 and the stabilizer 11 is located in the spacer insertion hole 23, the stabilizer 11 interferes with the spacer 30 and the spacer 30 is accommodated in the normal insertion position. When it becomes impossible, it can be detected that the terminal 10 is not in the normal accommodation position.

Further, when the terminal 10 is not in the normal accommodation position of the terminal accommodation chamber 21 and the stabilizer 11 is located behind the spacer insertion hole 23 in the opening 24, the stabilizer 11 exposed from the opening 24 is exposed. The terminal 10 is detected from the outside of the housing 20 by visual inspection or a detection device (electrical inspection by a conduction pin or the like, optical inspection by a camera or the like, etc.) to detect that the opening 24 is behind the spacer insertion hole 23. Can be detected that is not in the normal accommodation position.

Further, the positions of the stabilizers 11 exposed from the openings 24 can be visually confirmed for all of the plurality of terminal accommodating chambers 21. Therefore, in particular, when the terminal 10 should be accommodated only in a part of the terminal accommodating chambers 21 among the plurality of terminal accommodating chambers 21 due to the aspect of the connector side on the other side, the terminal accommodating chambers 21 are among the plurality of terminal accommodating chambers 21. By confirming from which opening 24 of the terminal accommodating chamber 21 the stabilizer 11 is exposed, whether or not the terminal 10 is accommodated in the terminal accommodating chamber 21 in which the terminal 10 should be accommodated can be determined from the outside of the housing 20. You can check from.
