Description

The present invention relates to a movable connector, particularly a movable connector suitable for a large current.

A plurality of terminals having a fixed housing, a movable housing that fits and connects with the connection object, a contact portion that makes conductive contact with the connection object, and a movable portion that displaceably supports the movable housing with respect to the fixed housing. Movable connectors are known. In the movable connector, the movable part located in the area between the fixed housing and the movable housing is elastically deformed, so that the movable housing is displaced with respect to the fixed housing and the position is displaced when the movable connector is fitted with the object to be connected. It is configured to absorb. The movable housing has a locking piece that regulates its displacement in the direction in which the object to be connected is removed by contacting the side of the fixed housing. Among these, for example, as shown in Patent Document 1, a movable connector in which a locking piece of a movable housing is provided on a side in a removal direction from a movable portion of a terminal is known.

Jikkenhei 05-023465 Gazette, FIG.

The amount of heat generated by the terminals increases, for example, when a large current is applied. At this time, heat tends to be trapped in the internal space of the movable connector that accommodates the terminal that is the source of heat. For example, in the case of a structure in which the locking piece acts as a barrier between the particularly movable part of the terminal and the external space of the movable connector such that the locking piece is located on the removal direction side of the movable part, the movable connector It becomes difficult for the heat accumulated in the internal space of the connector to be dissipated. Therefore, the reliability of the movable connector is lowered.

On the other hand, in order to avoid this problem, it is possible to consider a configuration in which the locking piece is provided on the fitting direction side of the connecting object with respect to the movable portion. In this case, for example, locking pieces can be provided on the side walls of the movable housing which are both outer sides in the terminal arrangement direction. However, in such a configuration, it is necessary to form a hole or the like in contact with the locking piece on the side wall of the fixed housing. Then, the strength of the side wall of the fixed housing tends to decrease, and the position where the fixing member for fixing the movable connector to the substrate is provided is limited. Further, a displacement allowance for the locking piece passing through the side wall of the fixed housing is required, so that the movable connector becomes large in the terminal arrangement direction, or electronic components cannot be arranged around the movable connector.

It is the present invention that has been made against the background of the above-mentioned prior art. An object of the present invention is to improve the heat dissipation of a movable connector.

In order to achieve the above object, the present invention is configured to have the following features.

That is, in the present invention, the first housing attached to the substrate, the second housing that fits and connects to the connection object, the contact portion that makes conductive contact with the connection object, and the second housing are said to be the second housing. A terminal having a movable portion that supports displaceably with respect to one housing, the second housing, and a storage space for the terminal are provided, and the first housing is fitted with the object to be connected. The second housing has a first engaging portion extending in an intersecting direction with respect to the direction, and the second housing engages in the displacement of the second housing in the removal direction opposite to the fitting direction. In a movable connector having a second engaging portion that contacts and regulates the joint portion, the second engaging portion has a heat radiating portion that allows heat in the housing space to flow to the external space. It is characterized by.

The heat generated from the terminals tends to be trapped in the storage space where the moving parts are housed. However, the second engaging portion of the movable connector of the present invention has a heat radiating portion capable of allowing heat in the accommodation space to flow to the external space. Therefore, according to the present invention, the heat in the accommodation space can be dissipated to the outside of the movable connector through the heat radiating portion.

The heat radiating portion can be formed of a through hole penetrating the second engaging portion.

According to the present invention, since the heat radiating portion is composed of a through hole penetrating the second engaging portion, the heat radiating portion can be easily formed, and the movable connector has a relatively simple structure. The heat dissipation can be improved.

The second engaging portion is composed of a plurality of engaging protrusions, and the heat radiating portion can be configured to be provided between the engaging protrusions adjacent to each other in the intersecting direction.

According to the present invention, since the second engaging portion is composed of a plurality of engaging protrusions, the weight of the second engaging portion is reduced as compared with the case where the second engaging portion is, for example, a large single engaging piece. The heat in the accommodation space can be dissipated to the outside from the heat radiating portion formed between the adjacent engaging protrusions.

The second housing can be configured to have an engaging projection connecting portion that connects the engaging projections that are adjacent to each other in the intersecting direction.

The second housing of the present invention has an engaging protrusion connecting portion for connecting adjacent engaging protrusions constituting the second engaging portion. Therefore, according to the present invention, the heat in the accommodation space can be dissipated to the outside while reinforcing the structure of the engaging protrusion.

The second engaging portion can be configured to be located on the side in the removal direction with respect to the movable portion.

Normally, in the case of a structure in which the second engaging portion is located closer to the removal direction of the object to be connected than the movable portion of the terminal, the second engaging portion is engaged between the particularly movable portion of the terminal and the external space of the movable connector. The pieces act as a barrier, making it difficult for the heat accumulated in the internal space of the movable connector to be dissipated. However, according to the present invention, since the second engaging portion has a heat radiating portion, even in a movable connector having such a structure, heat in the accommodation space is dissipated to the outside of the movable connector through the heat radiating portion without any problem. can do. Moreover, according to the present invention, since the second engaging portion is located closer to the moving portion in the removal direction of the object to be connected, for example, a locking piece is attached to the side wall of the movable housing which is both outer sides in the terminal arrangement direction. It is not necessary to form a hole or the like in contact with the locking piece on the side wall of the fixed housing in order to provide the above. Therefore, the strength of the side wall of the fixed housing is not likely to decrease, and the position where the fixing member for fixing the movable connector to the substrate is provided is not limited. Further, since the displacement allowance of the locking piece passing through the side wall of the fixed housing is not required, the movable connector does not become large in the terminal arrangement direction, and the electronic component can be arranged around the movable connector without any problem.

At least a part of the movable portion can be configured to be positioned so as to overlap the heat radiating portion from the viewpoint from the fitting direction.

A part of the movable portion of the present invention is positioned so as to overlap the heat radiating portion from the viewpoint from the fitting direction. Therefore, there is nothing that hinders heat convection between a part of the movable portion and the heat radiating portion. Therefore, according to the present invention, the heat in the accommodation space generated from the movable portion of the terminals can be dissipated to the outside.

The movable portion has a folded portion on the removal direction side, and the folded portion can be configured to be positioned so as to be displaced from the heat radiating portion from the viewpoint from the fitting direction.

The folded portion of the movable portion of the present invention is located away from the heat radiating portion from the viewpoint from the fitting direction. Therefore, the folded portion is not exposed through the heat radiating portion from the viewpoint from the fitting direction. Therefore, according to the present invention, even if a foreign substance or the like passes through the heat radiating portion, it does not hit the folded portion, so that the movable portion can be prevented from being damaged.

The first housing has an exposed portion that communicates with the heat radiating portion and exposes the heat radiating portion to the outside of the first housing, and has an exposed portion that exposes the heat radiating portion to the outside of the first housing. The exposed portion can be configured to overlap the heat radiating portion that is displaced together with the second housing.

The first housing of the present invention has an exposed portion that communicates with the heat radiating portion and exposes the heat radiating portion to the outside of the first housing. The movable connector is formed so that at least a part of the exposed portion overlaps with the heat radiating portion from the viewpoint of the fitting direction, no matter how the heat radiating portion is displaced within the movable range of the second housing with respect to the first housing. Has been done. Therefore, in the movable connector, the displacement of the second housing with respect to the first housing does not cover the entire region of the heat radiating portion with the first housing. Therefore, according to the present invention, heat in the accommodation space can be dissipated to the outside of the movable connector through the heat radiating portion regardless of the displacement position of the second housing with respect to the first housing.

The first housing can be configured to have an erroneous insertion prevention portion that partially covers the exposed portion to prevent erroneous insertion of the connection object.

An erroneous insertion prevention portion is formed in the exposed portion of the first housing of the present invention. The erroneous insertion prevention portion divides the exposed portion, for example, and makes the cross-sectional area of each divided region smaller than the cross-sectional area of the object to be connected. Therefore, the object to be connected does not pass through the exposed portion, and erroneous insertion into the movable connector is prevented.

The erroneous insertion prevention portion extends along the extension direction of the terminal to divide the exposed portion into individual exposed holes, and at least a part of the movable portion is the exposed hole from the viewpoint of the fitting direction. It can be configured to be positioned so as to overlap with.

A part of the movable portion of the present invention is located so as to overlap the exposed hole from the viewpoint from the fitting direction. Therefore, a path for heat convection is formed between a part of the movable portion and the exposed hole. Therefore, according to the present invention, the heat in the accommodation space generated from the movable portion of the terminals can be dissipated to the outside.

The first housing has a wall portion that surrounds the accommodation space, and the wall portion can be configured to have a window portion that communicates the accommodation space with the external space.

The wall portion of the first housing of the present invention configured to surround the accommodation space has a window portion that communicates the accommodation space with the external space. Therefore, by supplying air from the external space to the accommodation space using the window portion as an air supply port, it is possible to create an air flow from the accommodation space to the external space via the heat dissipation portion. Therefore, according to the present invention, the heat in the accommodation space can be dissipated to the outside by utilizing the air supply from the window portion.

The second engaging portion can be configured to extend along the extending direction of the movable portion.

The second engaging portion of the present invention extends along the extending direction of the movable portion. Therefore, it is not necessary to form the second engaging portion so as to extend in the movable portion, that is, the arrangement direction of the terminals. Therefore, the movable connector can be miniaturized in the terminal arrangement direction. Further, the second engaging portion extends longer in the extending direction of the movable portion than in other directions. Therefore, according to the present invention, a longer engagement allowance can be secured between the first engaging portion and the second engaging portion, and the second engaging portion displaced in the extraction direction side is the first. It is possible to disperse the stress when it comes into contact with the engaging portion of.

According to the present invention, the heat in the accommodation space can be dissipated to the outside of the movable connector through the heat radiating portion.

As shown in FIG. 1 and the like, the socket connector 1 includes a fixed housing 2 as a "first housing", a movable housing 3 as a "second housing", and a plurality of terminals 4. The socket connector 1 is mounted on the upper surface P2 as a "board surface" which is one surface of the circuit board P1 arranged along the X direction and the Y direction. The socket connector 1 is configured such that the movable housing 3 can be displaced with respect to the fixed housing 2. The plug connector is configured to be fitted from above the socket connector 1 with the downward direction in the Z direction approaching the upper surface P2 of the circuit board P1 as the fitting direction with the socket connector 1 so that the contacts are electrically connected to each other. Has been done.

Fixed housing 2

The fixed housing 2 is made of a resin molded body. As shown in FIG. 1 and the like, the fixed housing 2 is formed in a hollow rectangular parallelepiped shape which is the shortest in the Z direction and slightly longer in the X direction than in the Y direction. The fixed housing 2 is arranged on the upper surface P2 of the circuit board P1. Then, the fixed housing 2 is fixed to the circuit board P1 by the L-shaped fixing bracket 5 when the plate piece is folded in half and viewed from the front. The fixed housing 2 has fixing bracket mounting portions 2b extending in a groove shape in the Z direction at four corners in a plan view. Then, the fixing bracket 5 is fixed to the fixed housing 2 by press-fitting the L-shaped one side plate piece from the lower end side of the fixing bracket mounting portion 2b, and the L-shaped other side plate piece is soldered or the like. It is configured to be fixed to the circuit board P1.

The hollow fixed housing 2 has an accommodation space 2a between the hollow fixed housing 2 and the upper surface P2 of the circuit board P1 and is attached to the circuit board P1. The movable housing 3 and the terminal 4 are accommodated in the accommodation space 2a. As will be described later, the movable housing 3 has a movable side engaging portion 3a as a "second engaging portion", and the movable side engaging portion 3a is formed with a heat radiating portion 3b. (See FIGS. 5 and 6). Then, as will be described later, the terminal 4 has a movable portion 4c that is accommodated in the accommodation space 2a and supports the movable housing 3 in a displaceable manner with respect to the fixed housing 2 (see FIG. 3 and the like).

The fixed housing 2 constitutes a hollow rectangular parallelepiped exterior and surrounds the accommodation space 2a. The fixed housing 2 has a front wall portion 2c as a flat plate-shaped “wall portion”, a rear wall portion 2d as a “wall portion”, and “ It has side wall portions 2e and 2e as "wall portions" and upper wall portions 2f and 2f as "wall portions". The front wall portion 2c located in the front in the Y direction and the rear wall portion 2d located in the rear in the Y direction are both along the X direction and the Z direction. The lateral wall portions 2e and 2e located on both the left and right outer sides in the X direction are both along the Y direction and the Z direction, and connect the front wall portion 2c and the rear wall portion 2d. The upper wall portions 2f and 2f located in the front and the rear in the Y direction are connected to the upper end of the front wall portion 2c and the upper end of the rear wall portion 2d, respectively. The upper wall portions 2f and 2f are both along the X direction and the Y direction, and both are connected to the left and right side wall portions 2e and 2e.

An upper surface opening 2g having a rectangular peripheral edge in a plan view is formed on the upper surface of the fixed housing 2. The peripheral edge of the upper surface opening 2g is composed of front and rear upper wall portions 2f and 2f and left and right lateral wall portions 2e and 2e. The upper portion of the movable housing 3 housed in the storage space 2a is exposed to the outside from the upper surface opening 2g. In the fixed housing 2, the displacement of the movable housing 3 in the Y direction is regulated by the front and rear upper wall portions 2f and 2f forming the peripheral edge of the upper surface opening 2g, and the left and right lateral walls forming the peripheral edge of the upper surface opening 2g. The parts 2e and 2e regulate the displacement of the movable housing 3 in the X direction.

The upper wall portions 2f and 2f also function as "first engaging portions". That is, the fixed housing 2 has upper wall portions 2f and 2f extending in the X direction and the Y direction as intersection directions with respect to the fitting direction of the plug connector. The upper wall portions 2f and 2f come into contact with the movable side engaging portion 3a of the movable housing 3 and face upward in the Z direction of the movable housing 3 with respect to the fixed housing 2, that is, a plug in a direction opposite to the fitting direction of the plug connector. It has a function to regulate the displacement of the connector in the removal direction.

The fixed housing 2 has exposed portions 2h on the upper wall portions 2f and 2f that communicate with the heat radiating portion 3b of the movable housing 3 and expose the heat radiating portion 3b to the outside of the fixed housing 2. Here, the heat radiating portion 3b is displaced according to the displacement of the movable housing 3 with respect to the fixed housing 2. On the other hand, the socket connector 1 is formed so that at least a part of the exposed portion 2h overlaps with the heat radiating portion 3b in a plan view, no matter how the heat radiating portion 3b is displaced within the movable range of the movable housing 3 with respect to the fixed housing 2. Has been done. Therefore, in the socket connector 1, the movable housing 3 is displaced with respect to the fixed housing 2, so that the entire region of the heat radiating portion 3b is not covered by the fixed housing 2. Therefore, according to the present embodiment, the heat in the accommodation space 2a can be dissipated to the outside of the socket connector 1 through the heat radiating portion 3b regardless of the displacement position of the movable housing 3 with respect to the fixed housing 2.

For example, as shown in FIG. 5, the socket connector 1 of the present embodiment has two exposed portions 2h and two heat radiating portions 3b on the front side and the rear side thereof, respectively. When the movable housing 3 is not displaced with respect to the fixed housing 2, the inner regions of the exposed portions 2h in the Y direction overlap with the outer regions of the heat radiating portions 3b in the Y direction.

On the other hand, as shown in FIG. 6, when the movable housing 3 is displaced to the maximum in the movable range in the X direction and the Y direction with respect to the fixed housing 2, the two exposed portions 2h and the heat radiating portion 3b on the front side However, neither of them overlaps. However, the two exposed portions 2h on the rear side both overlap with the heat radiating portion 3b.

In this way, no matter how the movable housing 3 moves with respect to the fixed housing 2, the socket connector 1 is configured so that the heat radiating portion 3b is exposed in at least a part of the exposed portion 2h in a plan view. There is. Therefore, according to the present embodiment, the heat in the accommodation space 2a can be dissipated to the outside of the socket connector 1 through the heat radiating portion 3b regardless of the displacement position of the movable housing 3 with respect to the fixed housing 2.

More specifically, the exposed portion 2h is composed of exposed holes 2i penetrating the upper wall portions 2f and 2f in the Z direction. A partition wall 2j as an "erroneous insertion prevention portion" is formed in the exposed portion 2h so as to extend in the Y direction. That is, the exposed portion 2h both has an exposed hole 2i extending in the Y direction and a partition wall 2j. The partition wall 2j has a function of partially covering the exposed portion 2h to prevent erroneous insertion of the plug connector. The partition wall 2j divides the exposed portion 2h, for example, and makes the cross-sectional area of each of the exposed exposed holes 2i divided smaller than the cross-sectional area of the tip of the plug connector. Therefore, the plug connector does not pass through the exposed portion 2h, and erroneous insertion into the socket connector 1 is prevented.

Each of the "wall portions" that constitute the exterior of the fixed housing 2 and surround the accommodation space 2a may have a "window portion" that communicates the accommodation space 2a with the external space. In the present embodiment, the front wall portion 2c and the upper wall portion 2f, the rear wall portion 2d and the upper wall portion 2f have an extension direction side window portion 2k as a "window portion", and the lateral wall portion 2e is ". It has a window portion 2l on the array direction side as a "window portion".

The extension direction side window portion 2k on the front wall portion 2c side extends forward continuously along the Y direction from the exposed hole 2i formed in the front wall portion 2f, and extends from the upper end of the front wall portion 2c. It extends downward along the Z direction. The extension direction side window portion 2k on the side of the rear wall portion 2d extends rearward along the Y direction continuously from the exposed hole 2i formed in the upper wall portion 2f on the rear side, and the upper end of the rear wall portion 2d. It extends downward along the Z direction from. The extension direction side window portion 2k has a length of about 70% of the total height of the front wall portion 2c and the rear wall portion 2d.

The extension direction side window portion 2k is provided on the front wall portion 2c and the rear wall portion 2d, which are close to the terminal 4. Therefore, in the extension direction side window portion 2k, air can be supplied from the vicinity of the individual terminals 4. In the extension direction side window portion 2k, outside air can be directly introduced particularly toward the terminal 4 located on the central side in the X direction. Then, by introducing outside air having a relatively low temperature near the terminal 4 which is a heat generation source, a temperature difference is created inside the accommodation space 2a with the air warmed by the heat of the terminal 4. , Natural convection can easily occur. Therefore, by providing the extension direction side window portion 2k on at least one of the front wall portion 2c and the rear wall portion 2d, the heat in the accommodation space 2a is transferred to the outside by utilizing the air supply from the extension direction side window portion 2k. Can dissipate.

The arrangement direction side window portion 2l extends upward from the lower end of the side wall portion 2e along the Z direction. The arrangement direction side window portion 2l has a length of about 60% of the total height of the lateral wall portion 2e. The arrangement direction side window portion 2l has a width of about 2.5 times that of the extension direction side window portion 2k. The arrangement direction side window portion 2l is formed on the lateral wall portion 2e that is relatively distant from the terminal 4. Therefore, it is unlikely that a finger, a jig, or the like will come into contact with the terminal 4 from the outside through the array direction side window portion 2l formed on the side wall portion 2e. Therefore, the side window portion 2l in the arrangement direction can be formed in the lateral wall portion 2e with a large cross-sectional area, and the outside air can be introduced from the external space into the accommodation space 2a at a large flow rate. Therefore, by providing the arrangement direction side window portion 2l on at least one of the side wall portions 2e and 2e, the heat in the accommodation space 2a can be dissipated to the outside by utilizing the air supply from the arrangement direction side window portion 2l. it can.

As described above, the front wall portion 2c and the upper wall portion 2f, the rear wall portion 2d and the upper wall portion 2f have the extension direction side window portion 2k, and the side wall portion 2e has the arrangement direction side window portion 2l. Have. Therefore, by supplying air from the external space to the accommodation space 2a by using at least one of the extension direction side window portion 2k and the arrangement direction side window portion 2l as an air supply port, the accommodation space 2a is transferred to the external space via the heat dissipation portion 3b. And can create a flow of air. Therefore, according to the present invention, the heat in the accommodation space 2a can be dissipated to the outside more efficiently.

On the inner surface (accommodation space 2a) side of the front wall portion 2c and the rear wall portion 2d, a fixed side terminal holding portion 2m formed of a groove extending upward from the lower end in the Z direction is formed along the X direction. The fixed side terminal holding portion 2m has a function of holding the terminal 4.

The lower ends of the front wall portion 2c and the rear wall portion 2d are separated from the upper surface P2 of the circuit board P1 in the region where the fixed side terminal holding portion 2m is formed. That is, the external space and the accommodation space 2a communicate with each other below the fixed side terminal holding portion 2m. Therefore, in the socket connector 1, for example, even if the extension direction side window portion 2k and the arrangement direction side window portion 2l are not formed, the accommodation space 2a is formed from the gap between the fixed side terminal holding portion 2m and the upper surface P2. Outside air can be introduced.

A plurality of such fixed-side terminal holding portions 2m are formed side by side along the X direction for each of the front wall portion 2c and the rear wall portion 2d. In the present embodiment, since the socket connector 1 has two terminals 4 in the front and rear, two fixed side terminal holding portions 2m are also formed in the front wall portion 2c and the rear wall portion 2d, respectively.

Movable housing 3

The movable housing 3 is made of a resin molded body. As shown in FIGS. 1, 7, and the like, the movable housing 3 is formed in a hollow rectangular parallelepiped shape that corresponds to the fixed housing 2 and is longer in the X direction than in other directions.

The upper portions of the front wall 3c, the back wall 3d, and the side walls 3e and 3e project upward from the upper surface opening 2g formed on the upper surface of the fixed housing 2. Then, the front wall 3c and the back wall 3d come into contact with the front and rear upper wall portions 2f and 2f forming the peripheral edge of the upper surface opening 2g, respectively, so that the movable housing 3 is excessively displaced in the Y direction with respect to the fixed housing 2. It is regulated. Similarly, when the side wall portions 3e and 3e come into contact with the left and right side wall portions 2e and 2e forming the peripheral edge of the upper surface opening 2g, respectively, excessive displacement of the movable housing 3 with respect to the fixed housing 2 in the X direction is regulated. ing.

Further, the movable housing 3 of the present embodiment has a partition wall 3g extending in the Y direction and the Z direction so as to connect the front wall 3c and the back wall 3d facing each other. A fitting chamber 3h for the plug connector is formed inside the movable housing 3 (see FIG. 3 and the like), and an opening formed at the upper end of the fitting chamber 3h is an insertion port 3i for the plug connector. .. In the present embodiment, the partition wall 3g divides the internal space of the movable housing 3 into two at the center in the X direction, and the movable housing 3 has two fitting chambers 3h and two insertion ports 3i along the X direction. ing.

An insertion guide surface 3j, which is an inverted quadrangular pyramid-shaped inclined surface, is formed between the upper ends of both the top wall 3f and the partition wall 3g and the lower ends (insertion ports 3i) of both the top wall 3f and the partition wall 3g. There is. The insertion guide surface 3j is a portion that guides the plug connector that fits into the movable housing 3 toward the insertion port 3i and drops it into the fitting chamber 3h.

As shown in FIG. 3, the movable housing 3 has a movable side engaging portion 3a as a “second engaging portion”. The movable side engaging portion 3a has a function of restricting the displacement of the movable housing 3 with respect to the fixed housing 2 in the Z direction, that is, in the withdrawal direction of the plug connector, by coming into contact with the upper wall portion 2f of the fixed housing 2. doing. The movable side engaging portion 3a is arranged in the accommodation space 2a because it comes into contact with the lower surface side of the upper wall portion 2f located at the front portion and the rear portion of the fixed housing 2 in the Y direction. Therefore, the movable side engaging portion 3a is formed, for example, in front of the front wall 3c of the movable housing 3 and behind the back wall 3d.

As shown in FIG. 3, the movable side engaging portion 3a is located above the movable portion 4c of the terminal 4 in the Z direction. The movable side engaging portion 3a is arranged close to the upper wall portion 2f. Therefore, the movable side engaging portion 3a is located between the movable portion 4c and the external space of the socket connector 1, and tends to be a barrier when air flows from the accommodation space 2a to the external space. As described above, the socket connector 1 accommodates the movable portion 4c in the case where the movable side engaging portion 3a acts as a barrier between the movable portion 4c of the terminal 4 and the external space of the socket connector 1. The heat generated from the terminal 4 is likely to be trapped in the accommodation space 2a.

On the other hand, the movable side engaging portion 3a has a heat radiating portion 3b in which the heat in the accommodation space 2a is convected to the external space. As a result, not only the heat in the accommodation space 2a is transferred to and from the external space by heat conduction, but also the air having heat in the accommodation space 2a is directly transferred to the external space by convection through the heat radiating portion 3b. Therefore, according to the present embodiment, the heat in the accommodation space 2a can be dissipated to the outside of the socket connector 1 through the heat radiating unit 3b.

For example, the heat radiating portion 3b can be formed of a through hole that penetrates the flat plate-shaped movable side engaging portion 3a in the plate thickness direction (Z direction). In this case, the heat radiating portion 3b can be easily formed, and the heat radiating property of the socket connector 1 can be improved even though the structure is relatively simple. The hole surface of the heat radiating portion 3b viewed from the Z direction may be a circular shape or a polygonal shape such as a quadrangle. The heat radiating portions 3b may be one or a plurality.

As shown in FIG. 7, the movable side engaging portion 3a is composed of, for example, a plurality of engaging protrusions 3k. The engaging protrusions 3k extend forward from the front wall 3c in the Y direction and from the back wall 3d to the rear in the Y direction above the center of the movable housing 3 in the Z direction. As described above, the engaging projection 3k of the present embodiment extends along the Y direction, which is the extending direction of the movable portion 4c. Therefore, it is not necessary to form the engaging projection 3k so as to extend in the movable portion 4c, that is, in the X direction, which is the arrangement direction of the terminals 4. Therefore, the socket connector 1 can be miniaturized in the X direction.

Further, the engaging protrusions 3k are formed in a square columnar shape that is longer in the Y direction than in other directions, and as shown in FIG. 5, the movable housing 3 itself is in the Y direction in a state where the movable housing 3 is not displaced. More than half has a length that overlaps with the upper wall portion 2f. According to such a socket connector 1, a longer engagement allowance can be secured between the upper wall portion 2f and the engaging protrusion 3k, and the engaging protrusion 3k that is displaced upward in the Z direction is the upper wall portion 2f. The stress at the time of contact can be dispersed.

Three engaging protrusions 3k are formed in the front and rear in the Y direction. The three engaging protrusions 3k are arranged on both outer sides of the movable housing 3 in the X direction and at the center in the X direction. The outer surfaces of the engaging projections 3k on both outer sides in the X direction are formed flush with the side wall 3e. As a result, when the movable housing 3 is largely displaced in the X direction with respect to the fixed housing 2, the engaging projection 3k and the side wall 3e hit the side wall portion 2e. Therefore, the engaging projection 3k can disperse the pressure of the movable housing 3 that hits the side wall portion 2e without hindering the regulation of excessive displacement of the movable housing 3.

The upper surface of the engaging protrusion 3k is connected perpendicularly to the movable housing 3 in a side view. As a result, even if the movable housing 3 is largely displaced upward in the Z direction or in the Y direction, the upper wall portion 2f of the fixed housing 2 receives it on the surface and disperses the pressure of the movable housing 3 that hits the upper wall portion 2f. Can be done. On the other hand, the lower surface of the engaging protrusion 3k is connected to the movable housing 3 via a quadrangular curve in a side view. As a result, the connecting base of the engaging protrusion 3k to the movable housing 3 becomes thick, and the strength of the engaging protrusion 3k can be sufficiently ensured.

In the movable housing 3 of the present embodiment, as shown in FIG. 7 and the like, the heat in the accommodation space 2a is externally generated between the engaging projections 3k and 3k that form the movable side engaging portion 3a and are adjacent to each other in the X direction. It has a heat radiating portion 3b that convects into the space. As shown in FIG. 3, the heat radiating portion 3b is formed so as to extend the gap between the adjacent engaging protrusions 3k and 3k along the Z direction. The heat radiating portion 3b serves as a flow path for air that is heated in the accommodation space 2a and moves to the upper part. The heat of the accommodation space 2a is carried to the external space by convection passing through the heat radiating unit 3b. According to such a socket connector 1, the heat in the accommodation space 2a can be dissipated to the outside through the flow path formed between the engaging protrusions 3k and 3k.

In the movable housing 3, the amount of resin used as a material is reduced by the amount of the heat radiation portion 3b formed, as compared with the case where the movable side engaging portion 3a is, for example, a large single engaging piece. Therefore, the movable housing 3 can be reduced in weight by having the heat radiating portion 3b.

As shown in FIG. 7 and the like, the movable housing 3 of the present embodiment has an engaging projection connecting portion 3l that connects the engaging projections 3k adjacent to each other in the X direction. The engaging projection connecting portion 3l is formed in a square columnar shape that is longer in the X direction than in other directions. The engaging projection connecting portion 3l connects the tips of the engaging projections 3k and 3k and extends along the X direction. The engaging projection connecting portion 3l is formed so that its upper surface and lower surface are flush with the upper surface and lower surface of the engaging projection 3k, respectively. The engaging protrusion connecting portion 3l connects the tips of the engaging protrusions 3k and 3k to each other while leaving the heat radiating portion 3b in the movable housing 3. The hole surface of the heat radiating portion 3b has a quadrangular shape with rounded corners on the side of the engaging projection connecting portion 3l. According to such a socket connector 1, the heat in the accommodation space 2a can be dissipated to the outside while reinforcing the structure of the engaging projection 3k.

On the inner surface (fitting chamber 3h) side of the front wall 3c and the back wall 3d, a movable side terminal holding portion 3m formed of a groove extending upward from the lower end in the Z direction is formed along the X direction. The movable side terminal holding portion 3m has a function of holding the terminal 4.

A plurality of such movable side terminal holding portions 3m are formed side by side along the X direction for each of the front wall 3c and the back wall 3d. In the present embodiment, since the socket connector 1 has two terminals 4 in the front and rear, two movable side terminal holding portions 3m are also formed on the front wall 3c and the back wall 3d, respectively.

Terminal 4

As shown in FIGS. 2-4 and the like, the socket connector 1 of the present embodiment has two terminals 4 in the front and rear, respectively. And these four terminals 4 all have the same shape. Each of the four terminals 4 is arranged line-symmetrically with respect to the center line in the X direction of the socket connector 1 and is also arranged line-symmetrically with the center line in the Y direction as the axis. Then, as shown in FIG. 3, these plurality of terminals 4 are all attached to the socket connector 1 so that the plate width direction is the X direction and the plate surface is along the Y direction and the Z direction. Therefore, the plurality of terminals 4 are all arranged in the X direction and extend mainly in the Y direction. Here, one terminal 4 arranged on the rear side of the socket connector 1 will be described. The terminal 4 arranged on the front side of the socket connector 1 is the same as the terminal 4 arranged on the rear side except that the front and rear positional relationships are opposite.

As shown in FIG. 3 and the like, the terminal 4 has a substrate connecting portion 4a, a fixed side held portion 4b, a movable portion 4c, and a movable side held in this order from one end to the other end. It has a portion 4d and a contact portion 4e. The terminal 4 of the present embodiment is an electric conductor formed as a punched terminal obtained by punching a conductive metal piece of a flat plate by press working. Each functional portion of the terminal 4 and its shape are integrally formed by bending a punched conductive metal piece. That is, the terminal 4 of this embodiment is formed as a single component.

The board connection portion 4a is a portion for conductively connecting and fixing the terminal 4 to the circuit board P1. The board connection portion 4a is located below the other portion of the terminal 4 in the Z direction. The board connection portion 4a is fixed to the circuit board P1 by soldering or the like (see FIG. 3). Each of the terminals 4 of the present embodiment has five substrate connecting portions 4a having a square columnar shape that is longer in the Y direction than in other directions. Each of the five substrate connecting portions 4a is arranged at equal intervals along the X direction, and all extend along the Y direction.

The movable portion 4c is formed in a lateral S shape in a side view. The five movable portions 4c extending at equal intervals along the X direction all have the same shape.

The movable portion 4c extends forward from the upper end of the fixed-side held portion 4b in the Y direction and upward in the Z direction. The movable portion 4c has a folded-back portion 4f that changes the direction of the terminal 4 extending upward from the fixed-side held portion 4b in the upper region in the Z direction. The folded-back portion 4f is located at the upper end in the movable portion 4c.

The folded-back portion 4f may be positioned offset from the heat-dissipating portion 3b of the movable housing 3 from the viewpoint from the fitting direction, that is, in a plan view. As shown in FIGS. 2 and 3, the folded-back portion 4f of the present embodiment is positioned so as to overlap the engaging projection connecting portion 3l in a plan view. Therefore, the folded-back portion 4f is not exposed through the heat radiating portion 3b in a plan view. Therefore, according to the socket connector 1 having such a configuration, even if a foreign substance or the like passes through the heat radiating portion 3b, it does not hit the folded portion 4f, so that the movable portion 4c can be prevented from being damaged. ..

As shown in FIG. 3, the terminal 4 is formed in a tapered shape in a side view by being bent twice in the downward direction in the Z direction from the folded-back portion 4f to the movable side held portion 4d. The terminal 4 extends along the Y direction in the region from the folded-back portion 4f to the movable side held portion 4d, and as shown in FIG. 2, crosses the heat radiating portion 3b extending longer in the X direction in a plan view. There is. As described above, at least a part of the movable portion 4c is positioned so as to overlap the heat radiating portion 3b in a plan view. Therefore, there is nothing that hinders heat convection between a part of the movable portion 4c and the heat radiating portion 3b. Therefore, according to such a socket connector 1, the heat in the accommodation space 2a generated from the movable portion 4c among the terminals 4 can be quickly dissipated to the outside.

The movable side held portion 4d is a portion held by the movable side terminal holding portion 3m of the movable housing 3. The movable side held portion 4d is connected to the movable portion 4c and is located on the front side of the movable portion 4c. The movable side held portion 4d extends along the XZ plane and is formed in a flat plate shape that is longer in the X direction than in other directions. The movable side held portion 4d is composed of a single rectangular portion when viewed from the front. From one movable side held portion 4d, five movable portions 4c extend downward at equal intervals along the X direction, and three contact portions 4e extend upward at equal intervals along the X direction. It is extending to.

The contact portion 4e is housed in the fitting chamber 3h of the movable housing 3 as the movable side held portion 4d is inserted into the movable side terminal holding portion 3m, and is electrically connected to the plug connector. The contact portion 4e extends upward from the movable side held portion 4d. The contact portion 4e has an elastic piece 4e1 and a sickle blade-shaped contact piece 4e2.

The elastic piece 4e1 is configured such that the upper portion thereof is easily displaced in the front-rear direction with the lower portion of the elastic piece 4e1 connected to the movable side held portion 4d as an axis. The sickle blade-shaped contact piece 4e2 is connected to the upper end of the elastic piece 4e1 and is displaceably supported by the elastic piece 4e1. The sickle blade-shaped contact piece 4e2 is formed so as to project forward. The sickle blade-shaped contact piece 4e2 is configured to make a pressing contact with the plug connector from the rear to the front in the "contact direction with the connection object", which is the direction intersecting the terminal arrangement direction. ing.

The contact portion 4e of the present embodiment has a different shape between the two outer contact portions 4e in the X direction and the central contact portion 4e in the X direction. That is, the two outer contact portions 4e have an elastic piece 4e1 that is longer than the central contact portion 4e. Therefore, the sickle-shaped contact piece 4e2 of the two outer contact portions 4e is located above the sickle-blade-shaped contact piece 4e2 of the central contact portion 4e.

As described above, the movable side engaging portion 3a in the socket connector 1 of the present embodiment has a heat radiating portion 3b in which the heat in the accommodation space 2a is convected to the external space. Therefore, according to the present embodiment, the heat in the accommodation space 2a can be dissipated to the outside of the socket connector 1 through the heat radiating unit 3b.

Second Embodiment [FIGS. 8-9]

Hereinafter, the socket connector 21 as the second embodiment of the “movable connector” of the present invention will be mainly described with reference to the drawings, and a portion having a configuration different from that of the socket connector 1 described above will be described. That is, unless otherwise specified, the socket connector 21 can have the same effect as the socket connector 1 described above.

Configuration of Socket Connector 21 [FIGS. 8-9]

The socket connector 21 of the present embodiment includes a fixed housing 22 as a "first housing", a movable housing 23 as a "second housing", and a plurality of terminals 4. The terminal 4 is the same for the socket connector 1 and the socket connector 21.

Fixed housing 22

The fixed housing 22 of the present embodiment includes a front wall portion 22c as a "wall portion", a rear wall portion 22d as a "wall portion", side wall portions 22e and 22e as a "wall portion", and a "wall portion". It has upper wall portions 22f and 22f. Further, in the present embodiment, the front wall portion 22c and the upper wall portion 22f and the rear wall portion 22d and the upper wall portion 22f are a plurality of adjacent windows in the X direction with respect to the extension direction side window portion 22k as the “window portion”. It has a heat radiation plate 22n on the extension direction side. Then, in the present embodiment, the lateral wall portion 22e has a plurality of array direction side heat radiating plates 22o extending in the Z direction so as to divide the array direction side window portion 22l as the “window portion”. The fixed housing 22 is configured in the same manner as the fixed housing 2 except for the above.

The heat radiating plate 22n on the extension direction is a fin shape that projects outward from the lower end of the front wall portion 22c to the rear end of the upper wall portion 22f, one size larger than the outer surfaces of the front wall portion 22c and the upper wall portion 22f. It is formed in a flat plate shape). This also applies to the heat radiating plate 22n on the extension direction side formed on the side of the rear wall portion 22d. All of the heat radiating plates 22n on the extension direction extend along the YZ plane. The extension direction side window portion 22k is formed between the extension direction side heat radiating plates 22n and 22n adjacent to each other in the X direction. The heat radiating plate 22n on the extension direction side is formed on the partition wall 2j in the region where the partition wall 2j of the upper wall portion 22f is formed. The heat radiating plate 22n on the extension direction side is integrated with the partition wall 2j.

The heat radiating plate 22o on the arrangement direction side is formed in a fin shape (flat plate shape) extending outward from the upper end to the lower end of the side wall portion 22e, which is one size larger than the outer surfaces of the side wall portion 22e and the upper wall portion 2f. .. The heat radiating plates 22o on the array direction side all extend along the XZ plane. The arrangement direction side window portion 22l is formed between the arrangement direction side heat radiating plates 22o and 22o adjacent to each other in the Y direction.

The fixed housing 22 is configured to transfer heat in the accommodation space 2a to the heat radiating plate 22n on the extension direction side and the heat radiating plate 22o on the arrangement direction side by heat conduction, and exchange heat with the outside. By having the heat radiating plate 22n on the extension direction side and the heat radiating plate 22o on the arrangement direction side, the fixed housing 22 can more efficiently dissipate the heat in the accommodation space 2a to the outside.

The heat radiating plate 22o on the arrangement direction side can secure the strength of the side wall portion 22e. Therefore, the arrangement direction side window portion 22l is formed larger in the Y direction than the arrangement direction side window portion 2l. Therefore, since the side wall portion 2e has the heat radiating plate 22o on the arrangement direction side, the window portion 22l on the arrangement direction side can be formed with a larger cross-sectional area, and outside air can be introduced from the external space to the accommodation space 2a at a larger flow rate. Can be done. Therefore, when the fixed housing 22 has such a window portion 22l on the side in the arrangement direction, the heat in the accommodation space 2a can be dissipated to the outside in the flow path having a large cross-sectional area.

The heat radiating plate 22n on the extension direction side and the heat radiating plate 22o on the arrangement direction side of the present embodiment are integrally formed of the same resin material as the front wall portion 22c, the rear wall portion 22d, the side wall portions 22e and 22e, and the upper wall portions 22f and 22f. Has been done. However, the heat radiating plate 22n on the extension direction side and the heat radiating plate 22o on the arrangement direction side are not limited to the resin material, and another material having high thermal conductivity may be used.

Movable housing 23

The movable housing 23 of the present embodiment has a front wall 23c, a back wall 23d, side walls 23e and 23e, and a top wall 3f. Further, in the present embodiment, the front wall 23c has a front opening 23n, the back wall 23d has a back opening 23o, and the side walls 23e and 23e have side openings 23p and 23p, respectively. ing. The movable housing 23 is configured in the same manner as the movable housing 3 except for the above.

The front opening 23n is a through hole that penetrates the front wall 23c in the Y direction. The front opening 23n is formed in a region between the movable side terminal holding portion 3m (see FIG. 3 and the like) and the movable side engaging portion 3a in the Z direction. The front opening 23n is formed corresponding to the terminal 4. Therefore, two front openings 23n are arranged side by side along the X direction. Since the front wall 23c has the front opening 23n, the lower region of the contact portion 4e is exposed in the front view, and the heat generated in the contact portion 4e can be dissipated to the accommodation space 2a. The back opening 23o is the same as the front opening 23n except that the front-rear directions are different.

The side opening 23p is a through hole that penetrates the side wall 23e in the X direction. The side opening 23p extends upward from the lower end of the side wall 23e along the Z direction. The side opening 23p has a length of about 50% of the total height of the side wall 23e. Since the side wall 23e has the side opening 23p, the outside air introduced from the heat radiating plate 22o on the arrangement direction side of the fixed housing 22 can be supplied to the fitting chamber 3h, and the heat generated in the contact portion 4e is accommodated. It can dissipate into space 2a.

As described above, in the present embodiment, the heat in the accommodation space 2a can be dissipated to the outside of the socket connector 21 by the heat conduction by the fin structure and the convection by the “window portion”.

A gap is formed between the plurality of engaging protrusions 33k and 33k. In the present embodiment, the heat radiating portion 33b is not formed by a through hole, but a flow path is formed by a gap between the engaging projections 33k and 33k. Therefore, in the present embodiment, the weight can be reduced as compared with the case where the movable side engaging portion 33a has, for example, a large single engaging piece or the engaging protrusion connecting portion 3l. In the present embodiment, the heat in the accommodation space can be dissipated to the outside from the heat radiating portion 33b formed between the adjacent engaging projections 33k and 33k.

As described above, in the present embodiment, the heat in the accommodation space 2a can be dissipated to the outside of the socket connector 31 through the heat radiating portion 33b formed between the engaging projections 33k and 33k.
