The present invention relates to an OBD connector protective cover used as a cover that protects an OBD connector provided for a vehicle, and more specifically to the OBD connector with an enhanced abuse prevention effect.
Vehicles with a self-fault diagnostic function using a computer are provided with an OBD (On-board diagnostics) connector connected to the computer as means for acquiring a diagnosis result using the function. An OBD connector protective cover described in Japanese Patent Publication No. 5083924 is well-known as means for preventing illegal access to this type of OBD connector.
The OBD connector protective cover of Patent Literature 1 can accommodate the entire OBD connector in a body (102) from an opening (103), and closes the opening (103) with a key cylinder (120) and a slide cover (110) so as to prevent illegal access (abuse) to the OBD connector.
However, since the above-described OBD connector protective cover according to Patent Literature 1 is configured such that the key cylinder (120) is placed on a side thereof (see FIG. 1 and FIG. 2 of Patent Literature 1), the key cylinder (120) does not have much of a presence and the presence of the key cylinder (120) cannot be said to have a great effect of preventing the abuse of the OBD connector such as threatening an abuser of the OBD connector.
In addition, when the width dimension and depth dimension of the OBD connector are compared with those of an existing OBD connector, the width dimension is apparently longer (see width L2 and depth L3 of the OBD connector 100 shown in
The symbols in parentheses are reference numerals used in Japanese Patent Publication No. 5083924.
The present invention has been implemented to solve the above-described problems and it is an object of the present invention to provide an OBD connector with an enhanced abuse prevention effect and further provide a compact OBD connector protective cover also applicable to an OBD connector installed in a narrow space.
In order to attain the above object, the present invention provides an OBD connector protective cover to protect an OBD connector provided for a vehicle, including a body case that has an opening and can accommodate the entire OBD connector from the opening, a slide cover that is slidably attached to the body case and opens/closes the opening by sliding thereof, and a lock mechanism that includes a key cylinder placed on a forefront of the slide cover in a visually observable manner and locks the slide cover through operation of the key cylinder.
In the present invention, the body case may be structured to accommodate the OBD connector along a direction orthogonal to the width direction.
Moreover, in the present invention, the slide cover may include lugs that are functionally equivalent to lugs provided on both sides of an existing OBD connector or a joint that is functionally equivalent to a joint provided for the existing OBD connector.
In the present invention, the lock mechanism may include the key cylinder, a key plate that engages with a plate insertion hole of the slide cover and a plate engagement groove in the body case to thereby set the slide cover in a non-slidable state, and a lock pin that is inserted into a lock hole of the key plate from the key cylinder through operation of the key cylinder to thereby lock the slide cover set in a non-slidable state.
As a specific configuration of the OBD connector protective cover, the present invention is configured to place a key cylinder on a forefront of the slide cover in a visually observable manner so that anybody can recognize the presence of the key cylinder at a glance, having strong appeal of the presence of the key cylinder to the abuser of the OBD connector in particular, consequently causing the abuser to give up the intention of abusing the OBD connector, and can thereby provide an OBD connector protective cover with an enhanced abuse prevention effect.
As described above, the present invention provides the key cylinder on the forefront of the slide cover, and thereby has an advantage that the key cylinder can be easily operated when access to the OBD connector is necessary on occasions of automobile inspection or vehicle overhaul or the like.
Moreover, as a specific configuration of the body case in the OBD connector protective cover, the present invention adopts a configuration of the body case such that the entire OBD connector is accommodated along a direction orthogonal to a width direction thereof (longitudinal accommodation). For this reason, it is possible to reduce the width dimension of the body case in accordance with the depth dimension of the OBD connector which is by far shorter than the width dimension of the OBD connector, downsize the entire OBD connector protective cover in the width direction, provide a compact OBD connector protective cover applicable to an OBD connector installed in a narrow space, and obtain advantageous operations and effects such as increasing the number of types of vehicles in which the OBD connector protective cover can be installed. Since the entire OBD connector is accommodated in a longitudinal position as described above, it is more difficult to visually observe the back side of the OBD connector and more difficult to identify the harness (bundle of electric wires) on the back side of the connector. Thus, there is also an effect of making it difficult to make illegal access from the back side of the OBD connector such as connecting an illegal device to the harness on the back side of the OBD connector to illegally access a vehicle-mounted computer.

Hereinafter, a best mode for carrying out the present invention will be described in detail with reference to the accompanying drawings.
<<Overview of OBD Connector Protective Cover>>
The OBD connector protective cover 1 in
More specifically, the lock mechanism 6 has a structure provided with (A) the key cylinder 5, (B) a key plate 9 in
Referring to
<<Detailed Configuration of Body Case 3>>
Referring to
The connector chamber 13 has a shape whose top surface is open to function as the opening 2 to accommodate the entire OBD connector 100 and is provided behind the lock chamber 14. When the OBD connector 100 is accommodated in this connector chamber, the OBD connector 100 may be accommodated using a connector accommodation adapter frame 15 in
A connection terminal portion 101 of an existing OBD connector 100 has a standardized outside shape and dimension, but parts other than the connection terminal portion 101 of the existing OBD connector 100 such as a fitting 102 of the OBD connector 100 to attach the OBD connector 100 to the vehicle have varying outside shapes and dimensions depending on the type of vehicle or the like.
For this reason, when the existing OBD connector 100 is accommodated directly in the connector chamber 13 as is, an excessively large gap may be produced between the accommodated OBD connector 100 and the connector chamber 13, which may produce backlash of the OBD connector 100 due to vibration of the vehicle or the like, causing the OBD connector 100 to be accommodated unstably.
Use of the connector accommodation adapter frame 15 is effective as means for avoiding the above-described problem (unstable accommodation of the OBD connector 100). The connector accommodation adapter frame 15 is formed as a frame in size and shape so as to close fit into the connector chamber 13, and has a structure in which the connection terminal portion 101 of the OBD connector 100 can be fitted in the frame. For this reason, use of the connector accommodation adapter frame 15 allows the existing OBD connector provided for any vehicle to be firmly accommodated in the connector chamber 13 without backlash.
Furthermore, since the connector accommodation adapter frame 15 is fitted into a concave portion 13A (see
Referring to
Furthermore, in the lock chamber 14, a pair of plate engagement grooves 8 are formed as grooves with which both sides of the key plate 9 inserted in the lock chamber 14 engage. In the OBD connector protective cover 1 in
Although the mode of arrangement of the OBD connector 100 in the body case 3 (more specifically, inside of the connector chamber 13) is not shown in the drawings, for example, there can be a mode in which the OBD connector 100 is accommodated along the width L1 (see
When a width L2 of the existing OBD connector 100 is compared to a depth L3 as shown in
On the other hand, in the case of the aforementioned portrait accommodation, the width L1 of the body case 3 can be decreased in accordance with the depth L3 of the OBD connector 100, and it is thereby possible to downsize the OBD connector protective cover 1 in the width direction compared to the landscape accommodation and increase the number of types of vehicle in which the OBD connector protective cover 1 can be installed.

Two holes 22 formed in the rear surface of the body case 3 in
Such a configuration not only reduces deflection or backlash of the slide cover 4 but also makes it difficult to perform an illegal operation from the rear edge of the slide cover 4 such as inserting a sharp protrusion such as a flathead screwdriver into a tiny gap between the rear edge of the slide cover 4 and the body case 3, prying open the slide cover 4 and then illegally accessing the OBD connector 100 inside the body case 3, thus provides a high abuse prevention effect for the OBD connector 100.
A through hole 24 formed in the bottom surface of the body case 3, more specifically, in the bottom surface of the lock chamber 14 in
<<Detailed Configuration of Slide Cover 4>>
Referring to
The side plate 27 of the slide cover 4 is provided with a plurality of (two in the example in
The bottom edge of the side plate 27 of this slide cover 4 has an inwardly folded cross-sectional shape and the folded distal end portion is configured so as to slidably engage with the slide guide groove 20 in the outside bottom surface of the body case 3 as the slide guide rail 30.
In such a configuration, since the bottom edge of the side plate 27 of the slide cover 4 is hidden in the slide groove 20 in the outside bottom surface of the body case 3 without being exposed on the surface, the configuration makes it impossible to perform an illegal operation from the side plate bottom edge of the slide cover 4 such as inserting a sharp protrusion such as a flathead screwdriver into a tiny gap between the bottom edge of the side plate 27 and the body case 3, prying open the slide cover 4 and then illegally accessing the OBD connector 100 inside the body case 3, thus provides a high abuse prevention effect for the OBD connector 100.
As described above, since the respective slide guide grooves 20 and 29 and their corresponding slide guide rails 19 and 30 slidably engage with each other, the slide cover 4 is slidably attached to the body case 3 and sliding of the slide cover 4 allows the opening of the body case 3 (the opening 2 in the top surface of the connector chamber 13 and the opening 16 in the top surface of the lock chamber 14) to be opened/closed.
The top plate 26 of the slide cover 4 is configured in size and shape corresponding to the opening of the body case 3 (the opening 2 in the top surface of the connector chamber 13 and the opening 16 in the top surface of the lock chamber 14) and the top plate 26 of the slide cover 4 is placed over the opening of the body case 3, and in this way, the opening of the body case 3 is configured to be securely closed with the top plate 26.

Note that in the accommodation operation, the entire slide cover 4 need not always be removed from the body case 3 as shown in
When the accommodation operation of the OBD connector 100 is completed as described above, next, the slide cover 4 is made to slide from the front to back side of the body case 3 so that the opening of the body case 3 (the opening 2 in the top surface of the connector chamber 13 and the opening 16 in the top surface of the lock chamber 14) is closed with the slide cover 4 as shown in
Then, the key plate 9 is inserted from the plate insertion hole 7 of the slide cover 4 into the plate engagement groove 8 of the body case 3 (see
As described above, in the stage in which the slide cover 4 is set in a non-slidable state, the key plate 9 can be removed from the plate insertion hole 7 and locking of the slide cover 4 is not completed yet.
To complete the locking of the slide cover 4, a predetermined key operation is performed such as inserting the key into the key hole 12 of the key cylinder 5 and turning the key. The lock pin 11 then pops out from the rear surface 5a of the key cylinder 5 and is inserted into the lock hole 10 of the key plate 9 so that the key plate 9 cannot be removed from the plate insertion hole 7, and the locking of the slide cover 4 is thereby completed. The slide cover 4 is not allowed to slide in any direction unless the key plate 9 is removed.
The operation of accommodating the OBD connector 100 in the body case 3 of the OBD connector protective cover 1 in
The OBD connector 100 accommodated in the body case 3 of the OBD connector protective cover 1 as described above can be replaced in the original position before the accommodation, for example, by attaching it to a connector mounting plate P of the vehicle using the lugs 33 of the slide cover 4 as shown in
As a specific configuration of the above-described OBD connector protective cover 1 in
