In addition, the number of wheels is not limited to this example, and in other embodiments, the vehicle 1 may be another type of vehicle such as a four-wheeled vehicle.

FIG. 2 shows the structure of the connector structure 10 according to the present embodiment before connection. The vertical direction in the figure corresponds to the vertical direction of the vehicle 1. The connector structure 10 includes a male connector 11 and a female connector 12 that can be inserted and removed from each other. In the present embodiment, the female connector 12 is fixed to the vehicle body 2. On the other hand, the male connector 11 is a connector on the ECU side, and is inserted into the female connector 12 from below (in the direction indicated by the arrow in FIG. 2). In the drawing, the female connector 12 is shown in a cross-sectional view for easy understanding of its internal structure.

The male connector 11 has a terminal part 110 extending in the vertical direction and a base part 111 that supports and fixes the terminal part 110 on the lower end side. The function of the ECU is built in the base 111. Although details will be described later, the terminal portion 110 is provided with electrodes E11 to E18, and the base portion 111 is provided with a guide portion 1111 and a water reservoir portion 1112. The male connector 11 further includes a locking claw 112 for realizing fixation between the male connector 11 and the female connector 12 on the side surface portion of the base 111.

The female connector 12 has a terminal insertion portion 120 and a base 121 provided with the terminal insertion portion 120. In the terminal insertion portion 120, electrodes E21 and E23 to E28 are provided. Although details will be described later, the electrode E21 can be in electrical contact with the electrode E11 of the terminal portion 110 by inserting the terminal portion 110 into the terminal insertion portion 120. Similarly, the electrodes E23 to E28 can be electrically contacted with the electrodes E13 to E18 of the terminal portion 110 by inserting the terminal portion 110 into the terminal insertion portion 120, respectively. In addition, a locking hole 122 for realizing fixation between the male connector 11 and the female connector 12 is provided in the side wall portion of the terminal insertion portion 120.

FIG. 3 shows a structure of the connector structure 10 in a connected state, that is, a structure in which the male connector 11 and the female connector 12 are connected to each other (hereinafter, simply referred to as “connector connection state” in this specification). Indicates. In the connector connected state, the upper portion of the base 111 is inserted into the terminal insertion portion 120 together with the terminal portion 110, the locking claw 112 and the locking hole 122 are engaged with each other, and the male connector 11 and the female connector 12 are fixed together. Is done. In the connector connection state, the electrodes E11 and E13 to E18 and the electrodes E21 and E23 to E28 are in surface contact with each other and are electrically connected.

Although details will be described later, the electrodes E11 and E12 and the electrode E21 corresponding to the electrode E11 are detection electrodes for detecting water (water droplets) on the terminal portion 110. The electrodes E11 and E12 are adjacent to each other on the terminal portion 110. The electrode E12 has a pattern P12 that protrudes toward the electrode E11 above the water reservoir 1112 and is provided such that the distance L1 between the electrodes E11 and E12 is relatively short.

The electrodes E13 to E18 and the corresponding electrodes E23 to E28 are electrodes for signal communication, and signal communication is performed between the male connector 11 and the female connector 12 in the connector connection state. For example, the electrodes E13 to E18 and E23 to E28 supply power voltage (electric power) to the ECU in addition to electrodes for transmitting control signals for realizing control commands from the ECU such as clock signals and enable signals. The electrodes may also be included. In the present embodiment, a total of 12 electrodes (6 pairs) of the electrodes E13 to E18 and the corresponding electrodes E23 to E28 are exemplified as the signal communication electrodes. Are arranged as electrodes for signal communication.

As described above, the base 111 is provided with the guide 1111 and the water reservoir 1112. In the present embodiment, the guide portion 1111 is a portion where an inclined surface is formed in the upper portion of the base portion 111. Accordingly, the guide portion 1111 causes water generated in the space S surrounded by the region between the male connector 11 and the female connector 12, in this embodiment, the base portion 111 and the base portion 121, to move downward along the inclined surface. Can be moved. The water reservoir 1112 is a portion where a horizontal plane is formed at a position lower than the guide 1111 in the upper part of the base 111. Thereby, the water reservoir 1112 can store water generated in the space S and guided by the guide 1111.

The female connector 12 further includes a signal generator 123 in the base 121. Although details will be described later, in the connector connection state, the signal generator 123 functions as a determination unit that determines whether or not water wt has accumulated in the water reservoir 1112, and when water wt has accumulated, A detection signal is generated to indicate this.

Referring to the enlarged view of the region surrounded by the alternate long and short dash line in FIG. 3, the water wt adhering on the terminal portion 110 flows downward along the surface of the terminal portion 110 and, as shown by the arrows, guide portions 1111. The water is guided to the water reservoir 1112 through the inclined surface. Here, the detection electrodes E11 and E12 are located closer to the water reservoir 1112 than the guide portion 1111. In the present embodiment, the detection electrodes E11 and E12 are disposed at positions overlapping the water reservoir 1112 in the vertical direction. Therefore, when water wt accumulates across the electrodes E11 and E12 in the water reservoir 1112, a short circuit occurs between the electrodes E11 and E12. In this specification, this short means a state where an unexpected electrical path is formed between the electrodes E11 and E12 by water wt, and the impedance component (resistance component) may not be 0 [Ω].

In the connector connection state, for example, water wt may be generated later in the space S due to changes in the external environment such as temperature and humidity, and may adhere to the terminal portion 110. Alternatively, water wt may enter the space S in a car wash or the like and adhere to the terminal portion 110. According to this embodiment, the water wt generated in the space S in this way can be moved to the water reservoir 1112 by the guide portion 1111.

In the connector connection state, the signal generator 123 is electrically connected to the electrode E11 via the electrode E21. Different voltages are supplied to the electrodes E11 and E12. When water wt is accumulated in the water reservoir 1112 and the electrodes E11 and E12 are short-circuited, the potential of the electrode E11 varies. Therefore, the signal generator 123 can detect that when the electrodes E11 and E12 are short-circuited.

The voltage supplied to the electrodes E11 and E12 may be set so that the potential difference between them increases. For example, two of the two or more power supply voltages used in the ECU may be supplied to the electrodes E11 and E12, respectively, having the largest potential difference.

As an example, consider a case where among the electrodes E13 to E18, the electrodes E16, E17, and E18 supply power supply voltages of 0 [V], +12 [V], and −12 [V] to the ECU, respectively. In this case, +12 [V] and −12 [V] (or −12 [V] and +12 [V]) are preferably supplied to the electrodes E11 and E12, respectively.

As another example, among the electrodes E13 to E18, the electrodes E15, E16, E17, and E18 are respectively supplied with power supply voltages of 0 [V], +12 [V], +24 [V], and −12 [V] to the ECU. Consider the case of supply. In this case, +24 [V] and −12 [V] (or −12 [V] and +24 [V]) are preferably supplied to the electrodes E11 and E12, respectively.

When the voltage supplied to the electrodes E11 and E12 is set so that the potential difference between the electrodes E11 and E12 increases, when water wt accumulates across the electrodes E11 and E12, there is a comparison between the electrodes E11 and E12. Large current flows. As a result, the potential fluctuation of the electrode E11 increases, so that a short circuit between the electrodes E11 and E12 can be easily detected by the signal generator 123.

For example, a comparator is used for the signal generation unit 123, and the signal generation unit 123 detects that water wt has accumulated in the water reservoir 1112 based on whether or not the potential of the electrode E11 is within the reference range. Output a signal. In response to this detection signal, the vehicle 1 notifies the user (driver) that a short circuit has occurred at the terminal portion 110. This notification may be made, for example, by turning on a lamp such as an LED on an indicator. Based on this notification, the user can know that the maintenance of the connector structure 10 is necessary, and after that, the user may remove the water wt by himself or bring the vehicle 1 to the repair shop. Water wt may be removed.

In this embodiment, the signal generator 123 indicates that water wt has accumulated in the water reservoir 1112 based on whether or not the potential of the electrode E11 is within the reference range, specifically, a short circuit between the electrodes E11 and E12. Is detected. Therefore, an electrode (referred to as electrode E22) corresponding to the electrode E12 on the male connector 11 side is not provided on the female connector 12 side. However, the detection method of water wt is not limited to this. For example, as another embodiment, the electrode E22 is also provided on the female connector 12 side, and the signal generator 123 can detect the short circuit based on the potential difference between the electrodes E21-E22.

Further, since the electrode E12 has a pattern P12 protruding toward the electrode E11, the distance L1 between the electrodes E11 and E12 can be made relatively short. This facilitates detection of water wt in the water reservoir 1112. In the present embodiment, the distance L1 is smaller than the distance between any two of the signal communication electrodes E13 to E18. As a result, the electrodes E11 and E12 are short-circuited before a short circuit occurs between any of the electrodes E13 to E18. Therefore, before the abnormality caused by the water wt occurs in the signal communication of the electrodes E13 to E18, for example, the signal generator 123 can output the detection signal, and the user needs to maintain the connector structure 10. Can know.

The pattern P12 is provided above the water reservoir 1112, that is, at a position away from the water reservoir 1112 in the extending direction of the terminal portion 110. Therefore, according to the present embodiment, the allowable amount of water wt that can be stored in the water reservoir 1112 can be set with a relatively simple configuration. For example, as long as a small amount of water wt is accumulated in the water reservoir 1112, the signal communication of the electrodes E 13 to E 18 is appropriately executed, and the water wt may disappear due to evaporation with time. Therefore, for example, the signal generator 123 does not need to output a detection signal immediately because a small amount of water wt has accumulated in the water reservoir 1112. Thereby, according to this embodiment, the convenience of the connector structure 10 can be improved.

In the present embodiment, it has been described that the distance L1 between the pattern P12 of the electrode E12 and the electrode E11 is smaller than the distance between any two of the other electrodes E13 to E18. The configuration for reducing the distance is not limited to this. For example, instead of or in addition to the pattern P12, the electrode E11 may be provided with a pattern protruding to the electrode E12 side (referred to as a pattern P11). As another example, neither the pattern P12 nor the pattern P11 is provided, and the electrodes E11 and E12 are linear, and the distance between them is greater than the distance between any two of the other electrodes E13 to E18. You may extend so that it may become small. The electrodes E13 to E18 may be arranged at regular intervals, but may be arranged at different intervals.

FIG. 4 shows another structure of the male connector 11 as a modification of the first embodiment. In this example, the terminal portion 110 includes two

portions

110A and 110B that are separated from each other. The portion 110 </ b> A is disposed above the water reservoir 1112, i.e., at a position overlapping the water reservoir 1112 in the vertical direction. The portion 110B is disposed above the guide portion 1111, that is, at a position overlapping the guide portion 1111 in the vertical direction. The detection electrodes E11 and E12 are arranged in the portion 110A, and the signal communication electrodes E13 to E18 are arranged in the portion 110B.

According to this example, the portion 110B in which the electrodes E13 to E18 are disposed is located closer to the guide portion 1111 than the water reservoir portion 1112. Therefore, the water wt adhering to the portion 110B is quickly spilled by the guide portion 1111. Guided to the reservoir 1112. Therefore, it is possible to appropriately prevent a short circuit between the electrodes E13 to E18, that is, to reduce the influence of the water wt on the signal communication by the electrodes E13 to E18. On the other hand, the water wt adhering to the portion 110 </ b> A where the electrodes E <b> 11 and E <b> 12 are arranged tends to be accumulated in the water reservoir 1112. Therefore, it is possible to easily generate a short circuit between the electrodes E11 and E12, and it is possible to appropriately detect the water wt by the signal generation unit 123 (see FIG. 3). Therefore, the effect similar to 1st Embodiment is acquired also by this example.

In addition, here, the structure in which the entire portion 110A and the entire portion 110B are separated from each other is illustrated, but the terminal portion 110 may have a shape in which the

portions

110A and 110B are separated at least partially. For example, the

portions

110A and 110B may be connected on the base 111 side.

(Second Embodiment)
In the first embodiment described above, the portion where the horizontal plane is formed is the water reservoir portion 1112. However, the water reservoir portion 1112 may be provided at a position lower than the guide portion 1111 and is not necessarily horizontal. For example, the water reservoir 1112 may have an inclination angle smaller than that of the inclined surface of the guide part 1111, may be larger, or may be the same.

Figure 5 shows the structure of a state after the connection of the connector structure 10 ₂ of the second embodiment. This embodiment is different from the first embodiment mainly in that the guide part 1111 and the water reservoir part 1112 have inclined surfaces having the same inclination angle. That is, there is no distinction between the guide portion 1111 and the water reservoir portion 1112 due to the difference in the shape of the upper portion of the base portion 111.

However, since both the guide part 1111 and the water reservoir part 1112 have an inclined surface, when water wt is generated in the space S, the water wt is accumulated from the lower side. When the water level of the water wt reaches the electrode E12, the electrodes E11 and E12 are short-circuited, and the signal generator 123 (see FIG. 3) generates a detection signal. From this viewpoint, in this embodiment, the inclined surface illustrated on the left side of the electrode E12 can be distinguished from the guide portion 1111 and the inclined surface illustrated on the right side of the electrode E12 can be distinguished from the water reservoir portion 1112.

(Third embodiment)
Figure 6A, the third shows the structure of a connection state before the connector structure ₁₀₃ according to the embodiment, and FIG. 6B shows the structure of a state after the connection of the connector structure 10 _3. This embodiment is mainly different from the first embodiment in the positional relationship between the male connector 11 and the female connector 12. That is, in the present embodiment, the male connector 11 is disposed above the female connector 12. The male connector 11 is fixed to the vehicle body 2. The female connector 12 is a connector on the ECU side (the function of the ECU is built in the base 121), and is inserted into the male connector 11 from below.

In the present embodiment, a guide portion 1211 and a water reservoir 1212 are provided on the base 121 of the female connector 12. Specifically, the guide portion 1211 is a portion where an inclined surface is formed in the bottom surface portion in the terminal insertion portion 120. The water reservoir 1212 is a portion where a horizontal plane is formed at a position lower than the guide portion 1211 in the bottom surface portion in the terminal insertion portion 120.

The terminal portion 110 of the male connector 11 is provided with a notch 110T so that the terminal portion 110 has a shape corresponding to the guide portion 1211. The electrodes E13 to E18 are arranged at positions that overlap the notch 110T in the vertical direction, and the electrodes E11 are arranged at positions that do not overlap the notch 110T. The electrodes E11 and E13 to E18 are extended so that the electrodes E13 to E18 are shorter than the electrode E11 corresponding to the notch 110T of the terminal portion 110. In the present embodiment, the electrode E12 is not provided.

In the terminal insertion part 120, electrodes E21 to E28 are provided in the terminal insertion part 120. Similarly to the electrode E21, the electrode E22 is a detection electrode for detecting water wt, and is disposed adjacent to the electrode E21. The electrode E22 has a pattern P22 protruding toward the electrode E21 side, and the function thereof is the same as the function of the pattern P12 (see FIG. 3) described in the first embodiment. The electrodes E21 to E28 are extended so that the electrodes E23 to E28 are longer than the electrodes E21 and E22. As can be seen from FIG. 6B, in the connector connection state, the electrodes E11 and E13 to E18, and the electrodes E21 and E23 to E28 E28 is in surface contact with each other.

According to the present embodiment, the water generated in the region between the male connector 11 and the female connector 12, that is, the space S surrounded by the base 111 and the base 121 in this embodiment, is guided to the water reservoir 1212 by the guide portion 1211. Can be accumulated. Therefore, the same effects as those of the first embodiment can be obtained by this embodiment. In particular, in the present embodiment, the terminal portion 110 is positioned so as to be close to the guide portion 1211 and the water reservoir portion 1212 in the connector connected state because the notch 110T is provided. Therefore, the water wt adhering to the terminal part 110 falls easily to the guide part 1211 and the water reservoir part 1212 and is easily guided to the water reservoir part 1212.

(Fourth embodiment)
Figure 7A is a fourth shows the structure of a connection state before the connector structure ₁₀₄ according to the embodiment, and FIG 7B shows the structure of a state after the connection of the connector structure 10 _4. This embodiment mainly differs from the first embodiment described above in that the guide part 1111 and the water reservoir part 1112 are provided on the base part 111 side, and the guide part 1211 and the water reservoir part 1212 are provided on the base part 121 side. Different. That is, the base 121 is shaped as indicated by a broken line in FIG. 7A and engages with the shapes of the guide 1111 and the water reservoir 1112 of the base 111. Further, in this embodiment, the locking claw 112 is arranged at the side end of the terminal portion 110, and when the terminal portion 110 is inserted into the terminal insertion portion 120 and is in the connector connection state, the locking claw 112 and the locking claw 112 are engaged. The holes 122 engage with each other to fix the male connector 11 and the female connector 12 to each other. Note that the base 111 is not inserted into the terminal insertion portion 120 in the connector connection state.

According to the present embodiment, the water generated in the space between the male connector 11 and the female connector 12, that is, the space S surrounded by the base 111 and the base 121 in the present embodiment, is stored by the

guide portions

1111 and 1211. And 1212 can be stored. Therefore, the same effects as those of the first embodiment can be obtained by this embodiment. In particular, in this embodiment, the base 111 is provided with a guide 1111 and a water reservoir 1112, and the base 121 is provided with a guide 1211 and a water reservoir 1212, and the

bases

111 and 121 are engaged with each other. Therefore, according to the present embodiment, the correct orientation with respect to the female connector 12 when the male connector 11 is inserted is easy to understand. For example, the user inserts the male connector 11 in the wrong orientation and damages the terminal portion 110. Can also be prevented.

(Other)
As mentioned above, although some suitable aspects were illustrated, this invention is not limited to these examples, The one part may be changed in the range which does not deviate from the meaning of this invention. For example, other elements can be combined with the contents of each embodiment according to the purpose, application, etc., or a part of the contents of another embodiment can be combined with the contents of a certain embodiment. is there. In addition, it is needless to say that each term described in this specification is merely used for the purpose of describing the present invention, and the present invention is not limited to the strict meaning of the term. The equivalent can also be included.

For example, in each embodiment, the water wt that adheres to the terminal portion 110 later is considered, but the same applies to the case where other foreign matters (such as dust) that are not water wt adhere to the terminal portion 110. When a foreign substance enters the space S in the connector connected state, the foreign substance is guided to the water reservoir 1112 by the guide part 1111 due to gravity or vibration during traveling of the vehicle 1. When the foreign matter is conductive, the electrodes E11 and E12 are short-circuited by the foreign matter, so that the detection signal is output from the signal generator 123 as described above. Even when the foreign matter is not conductive, the impedance component (for example, a capacitive component) between the electrodes E11 and E12 changes, and thus the foreign matter can be electrically detected.

In each embodiment, the connector structure 10 for ECU is described. However, the contents of each embodiment can be applied to a connector structure for connecting other electronic components. Other electronic components may be mounted on the vehicle 1, but other electronic components may be used. For example, the contents of each embodiment can be applied to general electronic components that are connected to other terminals or devices and capable of signal communication, such as a display, a speaker, a sensor, and an actuator.

According to the 4th aspect, it is possible to implement | achieve a guide part and a water reservoir part with a comparatively simple structure.

In a fifth aspect, the terminal portion is a detection electrode (for example, for detecting that water has accumulated in the water reservoir portion in the first portion located closer to the water reservoir portion than the guide portion (for example, E11).
According to the fifth aspect, since the detection element is located near the water reservoir, it can be easily detected that water has accumulated in the water reservoir.

In the sixth aspect, a signal generator (for example, 123) that generates a signal for notifying the user of the fact that the detection electrode detects that water has accumulated in the water reservoir. Is further provided.
According to the sixth aspect, the user can know that maintenance of the connector structure is necessary, and can remove water by himself or go to a repair shop and have the water removed.
