Description

  The present invention relates to an opening and closing object that opens and closes an opening of a vehicle body, such as a sliding door that moves back and forth of a vehicle body such as a wagon car and a one-box car, a sunroof, and the like. The present invention relates to a protector with a sensor in which a sensor for detecting the presence of a foreign object is output by outputting a corresponding signal when a foreign object such as a finger is sandwiched therebetween.

  As shown in FIG. 9, a car that opens and closes the opening of the vehicle body by a sliding door 1 (or back door) such as a wagon car, or a car that opens and closes the opening of a vehicle body by a sunroof 2 as shown in FIG. The sensor-equipped protectors 10 and 20 are attached.

For example, a protector 10 with a sensor that protrudes toward the front side of the vehicle body and extends vertically as shown in FIG. 11 is attached to the front end surface of the slide door 1.
As shown in FIGS. 12 and 13, the sensor-equipped protector 10 is attached to the front end surface of the slide door 1, and includes a mounting base portion 11 having a substantially U-shaped cross section including a vehicle inner side wall 11 a, a vehicle outer side wall 11 b and a connecting wall 11 c. A hollow portion 12 formed integrally therewith is provided. In the hollow portion 12, a part of a human body (finger or limb) is provided between the slide door 1 and a body side opening (in some cases, a front door (side door)). A sensor (pressure-sensitive sensor) S that detects the pinching and outputs a corresponding electric signal when a foreign object such as a pinch is pinched is attached (for example, see Patent Documents 1 to 4).
In addition, in the lower part of the protector 10 with the sensor, a channel portion 13 having a C-shaped cross section is integrally formed on the side of the vehicle interior side wall 11a of the mounting base 11, and the wire harness W connected to the pressure sensor S is held. . A plurality of holding lips 14, 14 are provided inside the mounting base 11, and a core 15 having a substantially U-shaped cross section is embedded in the mounting base 11 in order to increase rigidity. Further, a decorative lip 16 is provided on the vehicle outer side wall 11 b of the mounting base 11.

  The sensor (pressure sensor) S has two core wires (electrode wires) 31 and 32 extending in the vertical direction (longitudinal direction) provided on conductive rubber-like elastic bodies 34 and 35 provided through a space 33. The hollow portion 12 is fixed in the hollow portion 12 so as to be buried. When a foreign object is sandwiched between the slide door 1 and the body side opening when the slide door 1 is closed, the hollow portion 12 is partially pressed. The rubber-like elastic bodies 34 and 35 come into contact with each other and the two core wires 31 and 32 are short-circuited. The change in the electrical signal is transmitted to the control device 40 connected to the lead wire 36 connected to the two core wires 31 and 32 at the lower end portion of the protector 10 with the sensor, thereby detecting the presence of foreign matter. Is done. The lead wire 36 is bundled with a wire harness W in a state of being covered with an insulator, but the tip is a bare wire exposed from the covering portion 37.

In the lower end portion of the protector 10 with the sensor, as shown in FIG. 14, the lead wire 36 is superimposed on the two core wires 31 and 32 drawn in the longitudinal direction (left direction in FIG. 14), and resistance welding is performed. As shown in FIG. 15, the wire is connected by soldering (FIG. 14 (b)) and the space 33 is exposed at the end so that it is closed by the insert 25 (FIG. 14 (c)). By molding, a part of the connection part M, the insert 25 and the wire harness W is buried in the mold so as not to be exposed. The reason why the space portion 33 is blocked by the insert 25 is to prevent the molding material from flowing into the space portion 33 during mold molding and preventing the sensor function from being impaired.
Also, in the upper terminal portion of the protector with sensor 10, as shown in FIG. 16, the legs of the resistor 39 overlap the two core wires 31 and 32 drawn in the longitudinal direction (right direction in FIG. 16). In addition to being connected by resistance welding or soldering, the space portion 33 is closed by the insert 26, and then molding is performed so that the connection portion M, the insert 26, and the resistor 39 are buried inside the mold so as not to be exposed. Yes.
In FIGS. 15 and 16, the part of the mold forming is indicated by a dotted line.

JP 2010-15696 A Japanese Patent No. 3291233 JP 2005-114395 A JP 2001-297842 A

However, since the connection part M and the resistor 39 are affected by the injection molding pressure when embedded in the mold, the lower side of the protector with sensor 10 is not exposed from the mold part or the line is not damaged. In the terminal portion, it is necessary to firmly position the connecting portion M and the lead wire 36 on the surface of the insert 25 with an adhesive, and the connecting portion M and the resistor 39 are also inserted in the upper end portion of the protector 10 with the sensor. It was necessary to firmly fix the surface of 26 with an adhesive and position it.
For this reason, there has been a problem that a new bonding process is required and that the use of an adhesive increases the cause of bonding failure. Further, the use of the adhesive is likely to vary, and it is difficult to fix the connection part M and the resistor 39 in a stable state. Further, the fixing with an adhesive has a problem that once it is attached, it cannot be easily removed at the time of repair or replacement.
In addition, when variations occur in the connection work between the two core wires 31 and 32 and the lead wire 36 or the connection work between the two core wires 31 and 32 and the resistor 39, the lead wire 36 and the resistor There is also a problem that 39 feet jump out of the surface of the terminal portion.

On the other hand, Patent Document 1 describes that an end cap is inserted so that the resin does not enter the hollow part when the terminal part is molded, and no particular adhesive is used. In this case, there is no description about fixing the connecting portion.
In addition, Patent Document 2 describes using a metal piece that can be caulked and fixed to the connection portion of the cord, but it is troublesome because it is fixed by welding, and the structure is complicated. It does not describe the point of preventing the molding material from flowing into the hollow part during molding.
Furthermore, Patent Document 3 describes a method of simply molding a terminal portion by a process that can be easily automated. However, the method does not mold at one time but molds in multiple times.
Patent Document 4 describes that a pinch sensor and an electric wire terminal are electrically connected by a connector, but the connector has two terminals apart from an insertion connecting portion to be inserted into a hollow portion of the pinch sensor. Since it protrudes toward the pinch sensor, the structure is complicated. In addition, it is necessary to insert the two terminals while positioning them well so that they contact the lower edge of the metal electrode provided on the pinch sensor. Therefore, there is a problem that it takes time to assemble.

  Therefore, an object of the present invention is to provide a protector with a sensor that can easily fix a connection portion to an insert for preventing a molding material from flowing in without relying only on an adhesive.

In order to achieve the above object, the sensor-equipped protector according to the present invention includes a peripheral edge of an opening / closing object that opens and closes an opening of a vehicle body, such as an automobile door (1) and a sunroof (2), and the opening of the opening.

The presence of the foreign matter is detected by the change in the electrical signal, and at the terminal portion, the core wires (31, 32) are electrically connected to the control device (40) or the lead wires (36, 39a, 39b) connected to the electrical components. Connected to the So as to close the serial space (33), a insert with sensors protector whose one end is formed by molding in a state of being pressed in (50) (10),
The insert (50) has a structure in which a central plate (50C) made of a non-conductive material is sandwiched between upper and lower plates (50A, 50B) made of a conductive material at one end thereof, and the insert (50) is press-fitted Then, the upper and lower plates (50A, 50B) are brought into contact with the conductive materials (34, 35) covering the two core wires (31, 32), respectively, and the lead wires (50A, 50B) are connected to the lead wires (50A, 50B). 36, 39a, 39b) are respectively fixed ,
In addition, wiring grooves (53a, 53b) for receiving the lead wires (36, 39a, 39b) are formed on the surfaces of the upper and lower plates (50A, 50B), and the wiring grooves (53a, 53b). Holding members (54a, 39b) which abut against the lead wires (36, 39a, 39b) and restrict the floating of the lead wires (36, 39a, 39b) received from the upper and lower plates (50A, 50B). 54b) is provided .
Here, the “change in electrical signal” includes a change due to a short circuit between two core wires and a change in capacitance.

The present invention also provides a peripheral edge of an opening / closing object that opens and closes an opening of a vehicle body, such as an automobile door (1) and a sunroof (2), and a mounting base (11) attached to the peripheral edge of the opening, A hollow portion (12) is formed integrally with the mounting base portion (11), and two core wires (31, 32) each covered with a conductive material (34, 35) are provided via a space portion (33). When the hollow portion (12) is pressed and crushed by a foreign matter sandwiched between the opening and closing portion and the opening when the opening and closing member is closed, the presence of the foreign matter is detected by a change in the corresponding electrical signal. In the terminal portion, the core wires (31, 32) are electrically connected to the control device (40) or the lead wires (36, 39a, 39b) connected to the electrical components, and the space portion (33). So as to block the insert (50) A sensor with protector whose one end is formed by molding in a state of being press-fitted (10),
The insert (50) has a structure in which a central plate (50C) made of a non-conductive material is sandwiched between upper and lower plates (50A, 50B) made of a conductive material at one end thereof, and the insert (50) is press-fitted Then, the upper and lower plates (50A, 50B) are brought into contact with the conductive materials (34, 35) covering the two core wires (31, 32), respectively, and the lead wires (50A, 50B) are connected to the lead wires (50A, 50B). 36, 39a, 39b) are respectively fixed,
In addition, holes (55a, 55b) into which the lead wires (36, 39a, 39b) are respectively inserted are formed on the surfaces of the upper and lower plates (50A, 50B).

The present invention also provides a peripheral edge of an opening / closing object that opens and closes an opening of a vehicle body, such as an automobile door (1) and a sunroof (2), and a mounting base (11) attached to the peripheral edge of the opening, A hollow portion (12) is formed integrally with the mounting base portion (11), and two core wires (31, 32) each covered with a conductive material (34, 35) are provided via a space portion (33). When the hollow part (12) is pressed and crushed by a foreign object sandwiched between the opening and closing object and the opening when the opening / closing object is closed, the presence of the foreign object is detected by a change in the corresponding electrical signal. In the terminal portion, the core wires (31, 32) are electrically connected to the control device (40) or the lead wires (36, 39a, 39b) connected to the electrical components, and the space portion (33). So as to block the insert (50) A sensor with protector whose one end is formed by molding in a state of being press-fitted (10),
One end of the insert (50) has a plate-like structure made of a non-conductive material, and the lead wires (36, 39a, 39b) are fixed so as to protrude from the upper and lower surfaces, respectively, and the insert (50 ) Are press-fitted, and the fixed lead wires (36, 39a, 39b) are brought into contact with the conductive materials (34, 35) covering the two core wires (31, 32), respectively. To do.

  Further, the present invention is characterized in that a return member (56) for holding the insert (50) in a press-fitted state is provided on the surface on one end side of the insert (50).

  Note that symbols in parentheses indicate corresponding elements or corresponding matters described in the drawings and modes for carrying out the invention described later.

According to the protector with a sensor of the present invention, when molding the terminal portion, one end side of the insert has a structure in which a central plate made of a non-conductive material is sandwiched between upper and lower plates made of a conductive material, and lead wires are placed on the upper and lower plates. Since the upper and lower plates are respectively brought into contact with the conductive material covering the two core wires only by press-fitting the insert into the space between the two core wires covered with the conductive material, Even if the tips of the lead wires are not directly connected to each other, and are not overlapped, they are electrically connected.
Therefore, as shown in the conventional example, no adhesive is particularly used, and connection by resistance welding or soldering is unnecessary. As a result, there is no need for an extra step and there is no adhesion failure, and even after it is once attached, it can be easily removed by simply pulling out the insert when repairing or replacing.

  Further, in the present invention, a configuration is provided in which a wiring groove portion is formed on each surface of the upper and lower plates, and a holding member that abuts the lead wires to restrict the stored lead wires from floating on the surfaces of the upper and lower plates. Alternatively, since the holes into which the lead wires are respectively inserted are formed on the surfaces of the upper and lower plates, it is possible to easily fix the tip of the lead wire to the upper and lower plates on one end side of the insert.

  Further, according to the present invention, the lead wire is fixed so that one end side of the insert has a plate-like structure made of a non-conductive material and protrudes from the upper and lower surfaces thereof, and the lead wire itself is fixed when the insert is press-fitted. Can be brought into direct contact with the conductive material covering the two core wires. Also in this case, no adhesive is used, and connection by resistance welding or soldering is unnecessary. And it can simplify very much so that the one end side of insert may be made into the plate-shaped structure which consists of nonelectroconductive materials.

  Further, in the present invention, since a return member is provided on the surface on one end side of the insert to keep the insert press-fitted, the insert is inserted once into the space between the two core wires covered with the conductive material. Is prevented from easily coming off or shifting.

A protector with a sensor according to an embodiment of the present invention will be described with reference to the drawings.
The sensor-equipped protector 10 according to the embodiment of the present invention protrudes toward the front side of the vehicle body on the front end surface of the slide door 1 in an automobile in which the opening of the vehicle body is opened and closed by the slide door 1 as shown in FIG. When a foreign object such as a part of the human body (finger or limb) is caught between the sliding door 1 and the body side opening (which may be a front door (side door)) A sensor (pressure-sensitive sensor) S that outputs a corresponding electric signal is attached, and the parts shown in FIGS. 11 to 13 have the same configuration as that shown in the conventional example. The structure is different from the insert 25 shown in the conventional example, and as shown in FIGS. 1 to 3, the core wires (electrode wires) 31 and 32 and the legs 39a and 39b of the resistor 39 are electrically connected. As shown in FIG. 4, the lead wire 36 connected to the control device 40 for determining the presence of foreign matter from the core wires (electrode wires) 31 and 32 and the change in the electrical signal, as shown in FIG. The structure of the part which electrically connects is different. The same parts as those in the conventional example are denoted by the same reference numerals. Here, the “change in electrical signal” includes a change due to a short circuit between the two core wires 31 and 32 and a change in capacitance.

The sensor-equipped protector 10 is directly attached to a flange (not shown) formed on the slide door 21 and is integrally formed with the attachment base 11. The front end surface of the slide door 1 is closed when the slide door 1 is closed. If there is a foreign object such as a finger between the front end face and the body side opening, the hollow part 12 elastically contacts the foreign object, and the corresponding foreign signal is detected by detecting the foreign object incorporated in the hollow part 12 The sensor (pressure sensor) S includes two core wires (electrode wires (including twisted wires)) 31 and 32 extending in the vertical direction (longitudinal direction). It is fixed in the hollow portion 12 so as to be embedded in conductive rubber-like elastic bodies 34 and 35 provided through 33.
And in the upper terminal part of the protector 10 with a sensor, as shown in FIG. 1, the space part 33 of the hollow part 12 opened in the upper terminal part by the insert 50 is closed.

The insert 50 has a plate-like structure in which a central plate 50C made of a nonconductive material is sandwiched between an upper plate 50A and a lower plate 50B made of a conductive material, and one end side is press-fitted into the space portion 33 in the hollow portion 12. The other end side is a protruding portion 52 exposed to the outside from the hollow portion 12. The center plate 50C is made of, for example, olefin-based TPO or styrene-based TPS among polypropylene, polyethylene, polyethylene terephthalate, nylon, 6 nylon, 6-6 nylon, various thermoplastic elastomers (TPE), and TPE. Here, although the center plate 50C is sandwiched between the upper and lower plates 50A and 50B for the entire insert 50, only the insertion portion 51 may have a three-layer structure.
Although not particularly limited, here, the step portion 51S is provided by making the lateral width of the protruding portion 52 smaller than the lateral width of the insertion portion 51, and the contact portion with respect to the molding material covering these is increased.
The insertion part 51 closes the space part 33 without a gap with a cross-sectional shape substantially the same as or slightly larger than the space part 33 so as to be press-fitted into the space part 33 of the hollow part 12, so that the molding material can be used during subsequent molding. This prevents the sensor function from flowing into the space 33.

  In addition, on the surfaces of the upper and lower plates 50A and 50B, wiring groove portions 53a and 53b in which the tip ends of the legs 39a and 39b of the resistor 39 are respectively accommodated are formed. The wiring groove portions 53a and 53b are grooves which are gradually deepened from the protruding portion 52 to the insertion portion 51 side, so that the legs 39a and 39b of the resistor 39 are obliquely accommodated, thereby inserting the legs 39a and 39b of the resistor 39. Good. The groove depths of the wiring groove portions 53a and 53b are substantially the same or smaller than the diameters of the feet 39a and 39b of the resistor 39, and the feet 39a and 39b of the resistor 39 housed in the wiring groove portions 53a and 53b It protrudes from the surfaces of 50A and 50B. At this time, the tips of the legs 39a and 39b of the resistor 39 housed in the wiring grooves 53a and 53b are not in contact with each other.

  Further, the upper and lower plates 50A and 50B are in contact with the legs 39a and 39b of the resistor 39 accommodated in the wiring grooves 53a and 53b, so that the feet 39a and 39b of the resistor 39 are the surfaces of the upper and lower plates 50A and 50B. Holding members 54a and 54b are provided for restricting the air from rising from the bottom. The shape of the pressing members 54a and 54b is not particularly limited, but here is a semi-ring-shaped member straddling the wiring groove portions 53a and 53b, and is fixed while pressing the legs 39a and 39b of the resistor 39. Further, although the pressing members 54a and 54b are provided one by one on the surfaces of the upper and lower plates 50A and 50B, a plurality of pressing members 54a and 54b may be provided. Further, the material of the holding members 54a and 54b may be made of a non-conductive material as long as the legs 39a and 39b of the resistor 39 are always in contact with part of the upper and lower plates 50A and 50B made of a conductive material. Here, a metal (conductive material) was used.

  In the state where the insertion portion 51 of the insert 50 is press-fitted into the space portion 33 of the hollow portion 12, the upper and lower plates 50A and 50B are brought into contact with the conductive materials 34 and 35 covering the two core wires 31 and 32, respectively. . Here, since the legs 39a and 39b of the resistor 39 housed in the wiring grooves 53a and 53b protrude from the surfaces of the upper and lower plates 50A and 50B, when the insert 50 is press-fitted, at least the legs 39a and 39b of the resistor 39 are inserted. 39b is directly brought into contact with the conductive materials 34 and 35 covering the two core wires 31 and 32, respectively.

  The main body of the resistor 39 is fitted into a recess 52a provided at the end of the protrusion 52 and is held in a stable state.

As described above, the insertion portion 51 of the insert 50 is press-fitted into the space portion 33 of the hollow portion 12 opened at the upper end portion, so that the opened portion is closed and the legs 39a and 39b of the resistor 39 are made of a conductive material. The front surfaces (the upper plate 50A and the lower plate 50B) of the insertion portion 51 to which the tips of the wires are fixed contact the conductive materials 34 and 35 covering the two core wires 31 and 32, and the core wires 31 and 32 and the resistor 39 are electrically connected. Connected.
Thereafter, the upper end portion of the protector 10 with the sensor is molded, and the insert 50 and the resistor 39 are buried in the mold so as not to be exposed.

According to such a sensor-equipped protector 10, when the terminal portion is molded, the insert 50 has a structure in which a center plate 50C made of a non-conductive material is sandwiched between upper and lower plates 50A and 50B made of a conductive material, and the upper and lower plates 50A. , 50B, the tips of the legs 39a, 39b of the resistor 39 are fixed, and the upper and lower plates are simply press-fitted into the space between the two core wires 31, 32 covered with the conductive materials 34, 35. 50A and 50B are in contact with the conductive materials 34 and 35 covering the two core wires 31 and 32, respectively, so that the tips of the core wires 31 and 32 and the tips of the legs 39a and 39b of the resistor 39 are not directly connected to each other. However, both are electrically connected even if they are not overlapped.
Therefore, as shown in the conventional example, no adhesive is particularly used, and connection by resistance welding or soldering is unnecessary. As a result, there is no need for an extra step and there is no adhesion failure, and even after being attached, it can be easily removed by simply pulling out the insert 50 for repair or replacement.

  In addition, wiring grooves 53a and 53b are formed on the surfaces of the upper and lower plates 50A and 50B, respectively, and the legs 39a and 39b of the resistors 39 are accommodated in the surfaces of the upper and lower plates 50A and 50B. Since the holding members 54a and 54b that abut against the feet 39a and 39b of the resistor 39 to restrict the floating from the resistor 39 are provided, the feet 39a and 39b of the resistor 39 with respect to the upper and lower plates 50A and 50B on one end of the insert 50 are provided. The tip can be easily fixed.

In the embodiment of the present invention, the case where the insertion portion 51 of the insert 50 is press-fitted and closed in the space portion 33 of the hollow portion 12 opened in the upper end portion of the protector with sensor 10 has been described, but as shown in FIG. In addition, the present invention can be applied to a case in which the insertion portion 51 of the insert 50 is press-fitted and closed in the space portion 33 of the hollow portion 12 opened in the lower end portion of the protector with sensor 10.
At this time, the two lead wires 36 connected to the control device 40 are accommodated in the wiring groove portions 53a and 53b formed in the upper and lower plates 50A and 50B in a state of being exposed from the covering portion 37, and the pressing members 54a and 54b. Is fixed by contacting. Then, the lead wires 36 projecting from the surfaces of the upper and lower plates 50A and 50B by the press-fitting of the insert 50 directly come into contact with the conductive materials 34 and 35 covering the two core wires 31 and 32, respectively.
Thereby, even if it does not connect the front-end | tip of the core wires 31 and 32 and the front-end | tip of the lead wire 36 directly, and both do not overlap, both are electrically connected.

In the embodiment of the present invention, the legs 39a and 39b of the resistor 39 and the lead wires 36 are accommodated in the wiring grooves 53a and 53b formed in the upper and lower plates 50A and 50B. As shown in FIG. It may be inserted into holes 55a and 55b formed in the upper and lower plates 50A and 50B and fixed by pressing members 54a and 54b.
At this time, since the legs 39a, 39b of the resistor 39 do not protrude from the surface, the legs 39a, 39b of the resistor 39 directly contact the conductive materials 34, 35 covering the two core wires 31, 32 by the press-fitting of the insert 50. Although not in contact with each other, the resistor 39 and the two core wires 31 and 32 are electrically connected by the portions of the upper and lower plates 50A and 50B coming into contact with the conductive materials 34 and 35, respectively. . Further, the resistor 39 is well fixed to the insert 50. And when press-fitting into the space portion 33 of the hollow portion 12, the end portions of the legs 39 a and 39 b of the resistor 39 are caught or damaged by the conductive materials 34 and 35 covering the two core wires 31 and 32. There is nothing. The holes 55a and 55b may be formed in advance, or may be formed by inserting and filling the legs 39a and 39b of the resistor 39 into the upper and lower plates 50A and 50B.

Further, in the embodiment of the present invention, the entire insert 50 has a three-layer structure in which the center plate 50C is sandwiched between the upper and lower plates 50A and 50B. It is not limited to.
Further, as shown in FIG. 6, the entire insert 50 (may be only on the insertion portion 51 side) is formed as a plate-like structure made of a non-conductive material so that the resistor 39 protrudes from the upper and lower surfaces thereof. The legs 39a and 39b are fixed, and when the insert 50 is press-fitted, the fixed legs 39a and 39b of the resistor 39 are directly brought into contact with the conductive materials 34 and 35 covering the two core wires 31 and 32, respectively. May be. Wiring grooves 53a and 53b may be formed on the upper and lower surfaces of the insert 50, and the legs 39a and 39b of the resistor 39 may be placed in the wiring grooves 53a and 53b so that parts of the legs 39a and 39b of the resistor 39 protrude. However, here, the legs 39a and 39b of the resistor 39 are fixed as they are to the upper and lower surfaces of the insert 50 without forming the wiring groove portions 53a and 53b.

Further, as shown in FIG. 7, a plurality of return members 56 may be provided on the surfaces of the upper and lower plates 50 </ b> A and 50 </ b> B of the insert 50 to hold the state where the insert 50 is press-fitted.
