In order to respond to this, a connection port device (in-vehicle connection device) capable of connecting an external device such as a portable device is provided on the console in the vehicle (Patent Document 1). When a portable device is connected to the connection port device, the portable device is connected to an in-vehicle system such as a car navigation system. And the function of a portable apparatus can be utilized via the monitor and speaker with which a vehicle-mounted system is provided.

JP 2011-29906 A

For example, as shown in FIG. 11A, the connection port device is assembled to the holding housing 62 that holds the connector 61 connected to the portable device, the cover panel 63 (FIG. 11B), and the holding housing 62. And an exterior housing 64 exposed on the front side of the cover panel 63.
As shown in FIG. 11A, the holding housing 62 and the outer housing 64 are assembled so that the locking beam 641 of the outer housing 64 is locked to the lock protrusion 621 of the holding housing 62.
Further, as shown in FIG. 11B, when the assembly of the holding housing 62 and the exterior housing 64 is inserted into the opening 630 of the cover panel 63 from the front side of the panel and attached to the cover panel 63, the assembly is completed.
And the terminal of a portable apparatus is connected to the fitting part 610 of the connector 61 exposed outside from the port hole 640 of the exterior housing 64 directly or via a cable.

As described above, the holding housing 62 and the outer housing 64 are separated. Although the holding housing 62 and the exterior housing 64 are integrated by locking the lock beam 641 to the lock protrusion 621, if an excessive load is applied to the connector 61 when inserting or removing a portable device, the lock beam 641 641 is separated from the lock protrusion 621 and separated.
In order to avoid separation of the holding housing 62 and the outer housing 64, the structure becomes larger if the lock beam 641 is thickened or the lock projection 621 is made high so that the lock beam 641 does not come off the lock projection 621.
Further, if the holding housing 62 and the exterior housing 64 are fixed by screwing, the number of parts and work processes increase, so the cost increases.

  An object of the present invention is to provide a connection port device capable of preventing parts from being separated while suppressing cost without causing an increase in size of the structure based on the above-described problems.

The present invention is a connection port device provided with a connector to which an external device is connected, a holding housing holding the connector, a cover panel having an opening through which the holding housing is passed, a cover housing and a cover housing. And an exterior housing partly exposed on the front side of the panel.
A lock beam formed on one of the holding housing and the outer housing is locked to a lock portion formed on the other, whereby the holding housing and the outer housing are locked.
In the present invention, at least one of a panel protrusion protruding from the inner periphery of the opening of the cover panel toward the lock beam and a beam protrusion protruding from the lock beam toward the inner periphery of the opening is formed. Features.

According to the present invention, one or both of the panel protrusions and the beam protrusions restricts the lock beam from being bent and detached from the lock portion. Therefore, even if a force in a direction separating the holding housing and the exterior housing is applied, the lock beam does not come off the lock portion, and the holding housing and the exterior housing are kept locked by the lock beam and the lock portion. .
Here, if the panel protrusion is not formed, the panel protrusion is located within a gap formed between the inner peripheral portion of the opening of the cover panel and the lock beam. The same applies to beam protrusions. Therefore, the formation of these protrusions does not cause an increase in the size of the connection port device.
If the lock beam is made thick so that the lock beam does not come off the lock part, the lock beam is improved in rigidity, and a large force is required to assemble the holding housing and exterior housing by bending the lock beam. However, according to the present invention, the assemblability does not deteriorate.
In addition, the panel projection that can be formed integrally with the cover panel and the beam projection that can be formed integrally with the exterior housing can prevent separation of the holding housing and the cover panel. Costs can be reduced without increasing the number of parts and work processes.
Therefore, according to the present invention, the holding housing and the exterior housing can be reliably held in a state where they are assembled to each other without increasing the size of the structure and suppressing the cost.

In the connection port device of the present invention, it is preferable that the front end of the panel projection is abutted against the proximal end side of the lock beam.
Then, since the front end of the panel protrusion supports the base end side of the lock beam, the support end of the lock beam moves toward the front end side by the amount of the panel protrusion. As a result, the effective length of the lock beam becomes shorter than the actual length of the lock beam, and the rigidity of the lock beam is increased, so that the lock beam is hardly bent. For this reason, detachment of the lock beam from the lock portion can be more sufficiently prevented.

In the connection port device of the present invention, it is preferable that the size of the panel protrusion in the thickness direction of the cover panel is larger than the thickness of the other part of the cover panel.
As a result, the range in which the bending of the lock beam is restricted by the panel protrusion is expanded in the length direction of the lock beam, so that the lock beam can be more sufficiently prevented from being detached from the lock portion.

In the connection port device of the present invention, the exterior housing has an exposed portion that is superimposed on the outside of the opening of the cover panel from the front side of the cover panel, and between the exposed portion and the panel lock portion formed on the outer periphery of the holding housing. It is preferable that the cover panel, the holding housing, and the exterior housing are integrated by sandwiching and locking the cover panel.
According to the above configuration, the holding housing and the outer housing can be stably attached to the cover panel by sandwiching the cover panel between the exposed portion and the panel lock portion of the holding housing. And the cover panel will be separated.
However, since the lock beam is prevented from being detached from the lock portion by the panel lock portion, the holding housing and the outer housing are not separated, and the cover panel is held between the holding housing and the outer housing.
That is, the holding housing and the exterior housing can be stably attached to the cover panel, and the holding housing, the exterior housing, and the cover panel can be maintained in an integrated state.

[First Embodiment]
The connection port device 10 of the first embodiment shown in FIG. 1 and FIG. 2 is an interface device provided in an in-vehicle system such as a navigation system and a music / video viewing system mounted in an automobile, and is provided on the console of the automobile.
The connection port device 10 has four connection ports P (FIG. 2B). The connection port device 10 can connect a maximum of four external devices connected to the connection port P to the in-vehicle system.
Typical examples of the external device include portable devices such as a music player, a DVD player, a digital camera, a PDA, and a game device.
The number of connection ports P is arbitrary, and the connection port device 10 may have only one connection port P.

  The connection port device 10 includes a cover panel 11, a holding housing 20 that holds a connector 12 (FIG. 3) connected to an external device, and a part of the connecting port device 10 that is assembled to the holding housing 20 and exposed to the front side of the cover panel 11. The exterior housing 30 is provided.

The cover panel 11 covers the inside of the connection port device 10. The holding housing 20 and the exterior housing 30 are attached to the cover panel 11.
The cover panel 11 can also be formed integrally with a panel that covers the internal structure of instruments and operation switches provided on the console.
The cover panel 11 can be formed by injection molding using a resin. The cover panel 11 can also be formed by punching a metal plate.

A substantially rectangular opening 110 is formed in the cover panel 11 (FIG. 2B).
A plurality of panel projections 111 for maintaining the holding housing 20 and the exterior housing 30 in an assembled state are formed on the inner peripheral portion 110 </ b> A of the opening 110.
In the present embodiment, there are four panel protrusions 111, all of which protrude from the inner periphery 110 </ b> A in a direction to narrow the opening 110. More specifically, each panel protrusion 111 protrudes from one of the pair of long sides of the opening 110 toward the other. Each position of the panel protrusion 111 corresponds to a position of a lock beam 32 of the exterior housing 30 described later.

In addition to the panel protrusion 111, the inner periphery 110 </ b> A of the opening 110 is also formed with a protrusion 112 for preventing an orientation error when the assembly of the holding housing 20 and the exterior housing 30 is attached to the cover panel 11. . One protrusion 112 is disposed on each of the pair of long sides of the opening 110.
In the present embodiment, the entire cover panel 11 including the panel protrusion 111 and the protrusion 112 is formed with a constant thickness.

The connector 12 (FIG. 3) mediates the connection between the external device and the in-vehicle system by being connected to the terminal. The illustration of the specific structure of the connector 12 is omitted.
The connector 12 may be provided with a circuit board for converting a signal transmitted / received between the external device and the in-vehicle system and adjusting the potential. In that case, the connector 12 has a connection part for connecting the terminal of the external device and the circuit board, and a connection part for connecting the terminal of the in-vehicle system and the circuit board.

As shown in FIG. 1, the holding housing 20 includes four receiving portions 21 that respectively receive the connectors 12.
The four receiving portions 21 are arranged in a row and are integrally formed.
Each receiving portion 21 is formed in a cylindrical shape having a rectangular cross section.
Inside the receiving portion 21, a guide groove 21A for guiding the connector 12 and a locking portion 21B for locking the received connector 12 are formed.

The holding housing 20 can be formed by injection molding using a resin. The same applies to the exterior housing 30.
The holding housing 20 is passed through the opening 110 of the cover panel 11.

A plurality of locking protrusions 22 for locking the exterior housing 30 and the holding housing 20 are provided on the outer periphery of the holding housing 20.
In the present embodiment, the lock protrusions 22 are formed in four places in total at the upper left and right ends of the holding housing 20 and the lower left and right ends.
The lock protrusion 22 is formed from a pair of ribs extending in the front-rear direction.
As shown in FIG. 3, an inclined surface 22 </ b> A that is inclined with respect to the outer peripheral surface 20 </ b> A of the holding housing 20 is formed on the front side of the lock protrusion 22.
On the rear side of the lock protrusion 22, a corner portion 22 </ b> B is formed that descends from the top surface continuing to the inclined surface 22 </ b> A toward the outer peripheral surface 20 </ b> A.

  Further, as shown in FIGS. 1 and 2A, panel lock beams 24 for locking the cover panel 11 and the holding housing 20 are formed at the left end and the right end of the holding housing 20.

Next, as shown in FIGS. 2A and 2B, the exterior housing 30 is integrally provided with a rectangular plate 31 and four lock beams 32 formed on the back surface of the plate 31. The exterior housing 30 and the holding housing 20 can be formed of the same resin or different resins.
The plate 31 is larger than the size of the opening 110 (FIG. 2B) of the cover panel 11. The outer peripheral portion of the back surface of the plate 31 is overlaid on the outside of the opening 110 of the cover panel 11.

Four port holes 310 are formed through the plate 31 in the thickness direction. The fitting port of the connector 12 held by the receiving portion 21 of the holding housing 20 is exposed to the outside through each port hole 310 (FIG. 3). A fitting port of the connector 12 indicated by hatching in FIG.
On the surface of the plate 31, a display indicating an external device connectable to each connection port P is attached.

As shown in FIGS. 2A and 3, the lock beam 32 is engaged with each of the lock protrusions 22 of the holding housing 20. As a result, the outer housing 30 and the holding housing 20 are locked so as not to be separated.
The lock beam 32 rises vertically at a position slightly inside from the outer peripheral edge of the back surface of the plate 31 and is formed in a thin plate shape.
A rectangular opening 32A (FIG. 2A) is formed over a range from the base end (support end) of the lock beam 32 to the front end (free end).

Next, an example of a procedure for assembling the connection port device 10 will be described.
First, as shown in FIG. 4A, the holding housing 20 is disposed on the back side of the plate 31 of the exterior housing 30, and the front end of the lock beam 32 of the exterior housing 30 is supported by the inclined surface 22A (FIG. 3) of the lock protrusion 22. It is assumed that
Then, the outer housing 30 and the holding housing 20 are brought closer to each other so as to receive the holding housing 20 inside the four locking beams 32 while guiding the locking beam 32 by the inclined surface 22A.
Then, the lock beam 32 bends and the tip 32B of the lock beam 32 gets over the lock projection 22 and is locked to the corner portion 22B of the lock projection 22 as shown in FIG. The lock protrusion 22 is inserted inside the opening 32 </ b> A of the lock beam 32. Further, the front end surface 20 </ b> B of the holding housing 20 is abutted against the back surface of the plate 31.
As described above, the holding housing 20 and the outer housing 30 are assembled.

Next, the assembly 23 of the holding housing 20 and the exterior housing 30 is attached to the cover panel 11.
As shown in FIG. 4B, the assembly 23 disposed on the front side of the cover panel 11 is inserted into the opening 110. At this time, if the vertical direction of the assembly 23 is wrong, the protrusion 112 (FIG. 1) interferes with the outer peripheral portion of the holding housing 20, and thus it can be seen that the vertical direction of the assembly 23 is incorrect. In that case, the assembly 23 is inserted into the opening 110 after the orientation 23 is corrected.
When the assembly 23 is inserted into the opening 110, the outer periphery of the holding housing 20 and the lock beam 32 pass through the inside of the four panel protrusions 111 formed on the inner peripheral portion 110 </ b> A of the opening 110. When the assembly 23 is inserted into the opening 110 until the back surface of the plate 31 abuts against the surface of the cover panel 11, the cover panel 11 is interposed between the back surface of the plate 31 and the panel lock beam 24 of the holding housing 20. It is pinched and locked. As a result, the assembly 23 of the holding housing 20 and the exterior housing 30 is attached to the cover panel 11.
Thereafter, when the connector 12 connected to the in-vehicle system is inserted inside each receiving portion 21 of the holding housing 20 and locked by the locking portion 21B, the connection port device 10 is completed (FIG. 3).

The procedure for assembling the connection port device 10 is not limited to the above.
It is also possible to connect the connector 12 to the in-vehicle system after the connector 12 is assembled to the holding housing 20 and the assembly 23 of the holding housing 20 and the exterior housing 30 is attached to the cover panel 11.

Now, with reference to FIG. 5A, the operation and effect of the lock beam 32, the lock protrusion 22, and the cover panel 11 will be described.
A broken line shown in FIG. 5A is the inner peripheral portion 110 </ b> A of the opening 110. Since the front end of the panel protrusion 111 protruding from the inner peripheral portion 110A is abutted against the proximal end side of the lock beam 32, the lock beam 32 is restricted from being bent (see a two-dot chain line).
Therefore, even when a force F is applied to pull out the outer housing 30 from the holding housing 20 when an external device is pulled out from the connector 12, the lock beam 32 is prevented from being detached from the lock protrusion 22.
Further, since the panel protrusion 111 supports the proximal end side of the lock beam 32, the support end of the lock beam 32 moves toward the distal end side by the amount of the panel protrusion 111. As a result, the effective length of the lock beam 32 becomes shorter than the actual length of the lock beam 32, and the lock beam 32 becomes difficult to bend. This also contributes to preventing the lock beam 32 from being detached from the lock protrusion 22.

As described above, the lock beam 32 is prevented from being detached from the lock protrusion 22, so that the holding housing 20 and the outer housing 30 against the external force that attempts to separate the holding housing 20 and the outer housing 30. Keep locked.
Here, as shown in FIG. 5B, a slight gap S <b> 1 may be provided between the tip of the panel protrusion 111 and the lock beam 32. Even in this case, the protrusion of the panel protrusion 111 from the inner peripheral portion 110A restricts the bending of the lock beam 32. Therefore, the lock beam 32 does not separate from the lock protrusion 22, and the holding housing 20 and the exterior housing 30 is kept locked. The clearance S1 is allowed as long as the dimension does not exceed the amount of displacement of the lock beam 32 when it is bent to the maximum.

  By holding the holding housing 20 and the outer housing 30 in a locked state, the cover panel 11 is also sandwiched and locked between the plate 31 of the outer housing 30 and the panel lock beam 24 of the holding housing 20. Kept in a state.

In this embodiment, the panel protrusion 111 used for holding the holding housing 20 and the exterior housing 30 is a gap S2 formed between the inner peripheral portion 110A and the lock beam 32 unless the panel protrusion 111 is formed (see FIG. 5 (a)). For this reason, the connection port device 10 is not enlarged by forming the panel protrusion 111.
Moreover, since the separation of the holding housing 20 and the exterior housing 30 can be prevented by using the cover panel 11 in which the panel protrusions 111 are integrally formed, unlike the case of using screws or the like to prevent the separation of both, Costs can be reduced without increasing the number of parts and work processes.
Therefore, according to the present embodiment, the holding housing 20 and the exterior housing 30 can be reliably held in a state where they are assembled to each other while suppressing the cost without increasing the size of the structure.

By the way, in this embodiment, the holding housing 20 and the exterior housing 30 can be stably attached to the cover panel 11 by sandwiching the cover panel 11 between the plate 31 and the panel lock beam 24, while the holding housing When 20 and the exterior housing 30 are separated, the cover panel 11 is also separated.
However, since the panel protrusion 111 prevents the lock beam 32 from being detached from the lock protrusion 22, the holding housing 20 and the outer housing 30 are not separated, and the cover panel 11 is held between the holding housing 20 and the outer housing 30. Is done.
That is, according to the present embodiment, the holding housing 20 and the exterior housing 30 can be stably attached to the cover panel 11, and the three of the holding housing 20, the exterior housing 30, and the cover panel 11 are integrated. Can keep.

  In this embodiment, the panel protrusion 111 corresponding to each of the four lock beams 32 is formed. However, in the present invention, the panel protrusion 111 faces only a part of the lock beams 32 instead of all of the plurality of lock beams 32. However, the case where the bending of the lock beam 32 is restricted by the panel protrusion 111 is also allowed. Even in this case, separation of the holding housing 20 and the exterior housing 30 can be prevented.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.
The connection port device 40 of the second embodiment shown in FIG. 6 is different from the connection port device 10 of the first embodiment only in the form of the panel protrusion of the cover panel 11.
Hereinafter, differences from the first embodiment will be described. The same code | symbol is attached | subjected to the structure similar to 1st Embodiment.

The cover panel 11 includes four rectangular parallelepiped blocks 15 formed on the inner periphery 110 </ b> A of the opening 110.
The block 15 protrudes toward the back surface 11 </ b> A side of the cover panel 11 and is formed thicker than other portions of the cover panel 11.
Each of the blocks 15 has a panel protrusion 151 that protrudes from the inner peripheral portion 110 </ b> A of the opening 110 in a direction to narrow the opening 110.

When the panel protrusion 151 is thicker than the thickness of the other part of the cover panel 11, the area where the tip of the panel protrusion 151 contacts the lock beam 32 is in the length direction of the lock beam 32 as shown in FIG. Enlarged.
As a result, the support end of the lock beam 32 moves further to the tip side than in the first embodiment, and the effective length of the lock beam 32 is further shortened. Therefore, the lock beam 32 can be more sufficiently prevented from being detached from the lock protrusion 22.

  Here, as shown in FIG. 7B, a gap S <b> 1 is allowed between the tip of the panel protrusion 151 and the lock beam 32. Even if there is a gap S <b> 1, if the lock beam 32 bends, it interferes with the panel protrusion 151, so that the lock beam 32 can be more sufficiently restricted from being detached from the lock protrusion 22.

  Since the block 15 of this embodiment is provided across the inside of the opening 110 and the outside of the opening 110, the panel protrusion 151 occupying the inside of the opening 110 is reinforced by a portion outside the opening 110. For this reason, the force which the panel protrusion 151 controls the bending of the lock beam 32 can be ensured more sufficiently.

[Modification of Second Embodiment]
FIG. 8 shows a modification of the second embodiment.
An annular thick portion 16 is formed along the inner peripheral portion 110 </ b> A of the cover panel 11.
The thick portion 16 integrally includes a block 15 that is locally formed in the inner peripheral portion 110A in the second embodiment and a portion 161 that connects the blocks 15 to each other.
The panel projection 151 of the block 15 provides the same effect as described in the second embodiment, and the strength of the inner peripheral portion 110A of the opening 110 can be improved by the annular thick portion 16.

In addition to the above, as long as the gist of the present invention is not deviated, the configuration described in the above embodiment can be selected or changed to another configuration as appropriate.
If a projection or the like that engages the cover panel 11 is formed on at least one of the holding housing 20 and the exterior housing 30, the panel lock beam 24 is formed on the holding housing 20 as described above, and the plate 31 and the panel lock beam 24 are formed. It is not necessary to sandwich and lock the cover panel 11 therebetween.
In other words, in the present invention, it is sufficient if the cover panel 11 is installed at a position where the panel protrusion protruding toward the lock beam 32 can be formed on the inner peripheral portion 110 </ b> A of the opening 110. It is not necessary to be locked to one or both of the housing 20 and the exterior housing 30.

The panel protrusion in the present invention is not limited to the form in each of the above embodiments, and can be modified to various forms.
For example, by extending the dimensions of the panel protrusions 111 and 151 in the thickness direction of the cover panel 11 to the position of the lock protrusion 22, it is possible to more reliably prevent the lock beam 32 from being detached from the lock protrusion 22.
Further, the number of panel protrusions 111 and the number of panel protrusions 115 are not limited. It is also possible to prevent the adjacent lock beams 32 from being separated by one panel protrusion.
The cover panel on which the panel protrusions are formed is not limited to a flat plate, but may be curved or have an uneven shape.

Further, the lock beam and the lock portion can be modified into various forms.
The opening 32A of the lock beam 32 may not be formed. In that case, a locking portion to be locked to the lock protrusion 22 can be formed in the lock beam 32.

  The lock beam and the lock portion can be provided at any location in the circumferential direction of the holding housing 20 and the exterior housing 30. And what is necessary is just to form the panel protrusion which protrudes toward a lock beam in the cover panel 11. FIG.

Furthermore, contrary to the above-described embodiments, the holding housing may include a lock beam, and the exterior housing may include a lock portion.
Specifically, for example, as shown in FIG. 9, the holding housing 20 is provided with a lock beam 25, a protruding piece 34 for receiving the locking beam 25 is provided on the exterior housing 30, and a locking protrusion 35 is formed on the protruding piece 34. To do.
Then, the bending of the front end side of the lock beam 25 where the lock protrusion 35 is located can be restricted by the panel protrusion 111 of the cover panel 11, and thus the lock beam 25 can be sufficiently prevented from being detached from the lock protrusion 35. .
A gap is allowed between the tip of the panel protrusion 111 and the lock beam 25.

By the way, instead of the panel protrusion formed on the cover panel 11 as described above, it is possible to prevent the lock beam from being bent and detached from the lock protrusion by the beam protrusion formed on the lock beam.
As shown in FIG. 10A, the lock beam 32 is formed with a beam protrusion 32 </ b> C that protrudes toward the inner peripheral portion 110 </ b> A of the opening 110 of the cover panel 11.
Since the beam protrusion 32C restricts the lock beam 32 from being bent and detached from the lock protrusion 22, the same effect as the first embodiment in which the panel protrusion 111 (FIG. 5A) is formed is obtained. It is done.
A gap is allowed between the tip of the beam protrusion 32C and the inner peripheral portion 110A of the cover panel 11.

FIG. 10B shows an example in which both the panel protrusion 111 and the beam protrusion 32C are formed. Since the panel projection 111 and the beam projection 32C restrict the flex beam 32 from being bent and detached from the lock projection 22, the same effects as those of the first embodiment can be obtained.
A gap is allowed between the tip of the beam projection 32C and the tip of the panel projection 111.
