[0001] The present invention relates to a connector connected to a magnet wire configured as an electric wire including a core wire and an enamel coating around the core wire.

Background Art

[0002] Conventionally, as a winding of an electric device such as an electric motor, a magnet wire configured as an electric wire including a core wire and an enamel coating around the core wire has been used. When an electric device such as an electric motor is connected to another device, a connector is connected to the magnet wire. As such a connector connected to a magnet wire, for example, the one disclosed in Patent Document 1 is known.

[0003] The connector disclosed in Patent Document 1 includes a housing (housing 184) and a contact (contact 102) inserted into the housing. The housing is provided with an insertion groove through which a magnet wire (magnet electric wire 103) is inserted, and a contact portion (ledge portion 185) that abuts against the magnet wire inserted into the insertion groove. The contact is configured to be inserted into the housing and press-connected to the magnet wire. This contact is configured to be press-connected to the magnet wire by having a slit blade that cuts through the coating of the magnet wire and bites into the magnet wire.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the connector disclosed in Patent Document 1, when the contact is pressed against the magnet wire, the areas of the contact and the magnet wire that are pressed against each other are exposed to the outside. That is, the areas of the slit blade of the contact and the magnet wire pressed against the slit blade that are pressed against each other are exposed to the outside through the insertion groove of the housing through which the magnet wire is inserted. Therefore, if the connector is used in a high-humidity environment or in an environment where saltwater may be sprayed, electrolytic corrosion will occur in the pressed-together portion of the slit blade of the contact and the magnet wire. Furthermore, if the core wire of the contact and the magnet wire are made of different metals, electrolytic corrosion will be even more likely to occur. If electrolytic corrosion occurs in the pressed-together portion of the contact and the magnet wire, it will lead to poor contact between the contact and the magnet wire.

[0006] Therefore, when connectors are used in harsh environments such as high humidity or environments where saltwater may be sprayed, a secondary treatment is required to prevent electrolytic corrosion by embedding the pressed-together portion of the contact and magnet wire in resin. In other words, after pressing the contact and magnet wire together, a secondary treatment such as resin potting is required to embed the pressed-together portion of the contact and magnet wire in resin. The need for such a secondary treatment increases the labor involved in installing the connector and also increases the cost of installing the connector.

[0007] In view of the above circumstances, the present invention aims to provide a connector that can prevent electrolytic corrosion from occurring in the pressed-together portion between the contact and the magnet wire, and that eliminates the need for a secondary treatment in which the pressed-together portion between the contact and the magnet wire is embedded in resin to prevent electrolytic corrosion. [Means for solving the problem]

[0008] (1) A connector relating to one aspect of the present invention for achieving the above objective relates to a connector connected to a magnet wire which is configured as an electric wire including a core wire and an enamel coating around it. Furthermore, a connector according to one aspect of the present invention comprises a housing provided with a slit-shaped insertion groove through which a magnet wire is inserted and a contact portion that abuts against the magnet wire inserted into the insertion groove; a contact having a slit blade that cuts through the covering and bites into the magnet wire, which is inserted into the housing and pressed against the magnet wire for connection; and a rubber member attached to the contact, wherein the rubber member covers the slit blade on both sides in the longitudinal direction of the magnet wire and has a slit blade cover portion that opens in a slit shape at a position corresponding to the insertion groove and has a slit groove through which the magnet wire is inserted, and in a state in which the contact with the rubber member attached is inserted into the housing and the contact and the magnet wire are pressed against each other, the area in which the contact and the magnet wire are pressed against each other is covered by the edge of the slit groove of the slit blade cover portion and the contact portion of the housing.

[0009] In this configuration, the contact with the rubber component attached is inserted into the housing, and the magnet wire, which is inserted into the insertion groove of the housing, is also inserted into the slit blade of the contact. As a result, the slit blade cuts through the insulation of the magnet wire and bites into it, pressing it against the magnet wire. This pressing contact between the contact and the magnet wire connects the connector to the magnet wire.

[0010] Furthermore, according to the above configuration, the rubber member that is attached to the contact and inserted into the housing together with the contact is provided with a slit blade cover portion. With the magnet wire inserted through the slit groove of the slit blade cover portion, which opens corresponding to the insertion groove of the housing, both sides of the slit blade are covered by the slit blade cover portion. Moreover, when the contact with the rubber member attached is inserted into the housing and the contact and the magnet wire are pressed together, the area where the contact and the magnet wire are pressed together is covered by the edge of the slit groove of the slit blade cover portion and the contact portion of the housing.

[0011] Therefore, with the above configuration, the areas of the contact's slit blade and the magnet wire pressed against the slit blade are covered by the rubber member and the housing, shielding them from exposure to the outside. In other words, the areas of the contact and the magnet wire pressed against each other are shielded by the rubber member and the housing, preventing them from being exposed to the outside through the insertion groove of the housing. For this reason, even when the connector is used in a high-humidity environment or in an environment where saltwater may be sprayed, the pressed-together portions of the contact's slit blade and the magnet wire are covered by the rubber member and the housing, shielding them from the outside. This prevents electrolytic corrosion from occurring in the pressed-together portions of the contact and the magnet wire.

[0012] Furthermore, as described above, with the above configuration, the pressed-together portion between the contact and the magnet wire is covered by the rubber member and housing, shielding it from the outside, and preventing electrolytic corrosion from occurring at the pressed-together portion between the contact and the magnet wire. Therefore, there is no need for a secondary treatment in which the pressed-together portion between the contact and the magnet wire is embedded in resin to prevent electrolytic corrosion. By eliminating the need for such a secondary treatment, the increase in labor during connector installation work can be suppressed, and the increase in connector installation costs can also be suppressed.

[0013] Therefore, according to the above configuration, it is possible to provide a connector that can prevent electrolytic corrosion from occurring in the pressed-together portion between the contact and the magnet wire, and eliminates the need for a secondary treatment in which the pressed-together portion between the contact and the magnet wire is embedded in resin to prevent electrolytic corrosion.

[0014] (2) The contact portion may be provided in the shape of a base on which the magnet wire inserted through the insertion groove is placed and made contact.

[0015] With this configuration, when the magnet wire is inserted into the insertion groove of the housing, the magnet wire can be brought into contact with the contact portion of the housing. Then, in that state, the contact with the rubber member attached is inserted into the housing and pressed against the contact and the magnet wire, and the pressed portion between the contact and the magnet wire can be covered by the slit blade cover portion of the rubber member and the contact portion of the housing. For this reason, the housing into which the contact with the rubber member attached is inserted can be configured as an integrated housing with an insertion groove and a contact portion. Thus, the housing of a connector that can shield the pressed portion between the contact and the magnet wire from the outside by covering it with the rubber member and the housing can be constructed from a single component.

[0016] (3) The slit blade cover portion has cover walls that cover the slit blade on both sides in the longitudinal direction of the magnet wire, and the slit groove may be provided in each of the cover walls that cover the slit blade on both sides in the longitudinal direction of the magnet wire.

[0017] This configuration allows for a simple slit blade cover section, where slit grooves are provided in each of the cover walls that cover both sides of the slit blade, thereby shielding the contacted portion between the contact and the magnet wire from the outside, together with the housing.

[0018] (4) The slit blade cover portion is provided with a bridging portion that bridges the cover wall portion that covers the slit blade on both sides in the longitudinal direction of the magnet wire, and the bridging portion may be provided so as to extend through the space between the slit blades.

[0019] This configuration allows the cover walls that shield the contacted portion between the contact and the magnet wire from the outside on both sides of the slit blade to be integrated with a simple structure consisting only of a bridging section. Furthermore, since the bridging section that integrates the cover walls on both sides of the slit blade is provided so as to penetrate between the slit blades, the cover walls on both sides of the slit blade can be integrated with a compact structure that fits in a small space.

[0020] (5) The rubber member may be provided with an attachment portion that is attached to the outer circumference of the contact in a strip-like manner over the circumferential direction of the contact.

[0021] With this configuration, when attaching the rubber member to the contact, the attachment portion of the rubber member, which extends in a strip shape circumferentially, is first stretched to expand its diameter and positioned along the outer circumference of the contact. After that, the attachment portion is elastically restored, allowing the rubber member to be easily attached to the outer circumference of the contact. Furthermore, because the rubber member is attached to the contact with the attachment portion extending circumferentially along the outer circumference of the contact, the rubber member attached to the contact becomes less likely to come off. As a result, the rubber member can be attached to the contact in a stable state that is less likely to come off.

[0022] (6) The housing comprises a first housing into which the through groove is provided and the contact with the rubber member attached is inserted, and a second housing provided separately from the first housing, which is provided and inserted into and fitted onto the slit blade of the contact when it is inserted into the first housing, wherein the second housing may be configured such that, when fitted onto the slit blade, the contact portion abuts against the magnet wire which is inserted through the through groove of the first housing and the slit groove of the rubber member.

[0023] In this configuration, a contact with a rubber component attached is inserted into the first housing, and the magnet wire is inserted through the insertion groove of the first housing and the slit groove of the rubber component, and the magnet wire is pressed against the slit blade of the contact. Then, a second housing, which is separate from the first housing and has a contact portion, is inserted into the slit blade and fitted into place, so that the contact portion comes into contact with the magnet wire inserted through the insertion groove of the first housing and the slit groove of the rubber component. As a result, the area where the contact and the magnet wire are pressed together is covered by the edge of the slit groove of the slit blade cover and the contact portion of the second housing. Consequently, the pressed-together portion of the contact's slit blade and the magnet wire is covered by the rubber component and the second housing, shielding it from external exposure. Therefore, according to the above configuration, even in the case of a connector in which the operation of inserting the contact into the first housing and pressing the magnet wire against the contact is required, and then inserting and fitting the second housing into the slit blade of the contact, the pressed-together portion of the contact and the magnet wire can be covered by the rubber member and the housing to shield it from the outside. [Effects of the Invention]

[0024] According to the present invention, it is possible to prevent electrolytic corrosion from occurring in the pressed portion between the contact and the magnet wire, and it is also possible to eliminate the need for a secondary treatment of embedding the pressed portion between the contact and the magnet wire in resin for preventing electrolytic corrosion, and a connector can be provided.

[0026] The embodiments for carrying out the present invention will be described below with reference to the drawings. The present invention can be widely applied to various uses as a connector connected to a magnet wire, which is configured as an electric wire including a core wire and an enamel coating around it.

[0027] [First Embodiment] (Overall connector configuration) Figure 1 is a perspective view of connector 1 according to a first embodiment of the present invention, showing the connector connected to a magnet wire 100. Figure 2 is a plan view of connector 1 connected to the magnet wire 100. Figures 3 to 6 are perspective views showing connector 1 connected to the magnet wire 100, including a cross-section.

Figure 6 is a perspective view of connector 1 showing a cross-section at the position indicated by arrow DD in Figure 2.

[0028] Referring to Figures 1 to 6, connector 1 is configured as a connector connected to a magnet wire 100. In this embodiment, connector 1 is configured to connect to a single magnet wire 100. The magnet wire 100 is provided as a winding for an electrical device such as an electric motor, and is configured as an electric wire including a conductor core wire 100a and an enamel coating 100b surrounding it as an insulator. The core wire 100a is made of, for example, copper or aluminum. Connector 1 is connected to the magnet wire 100 at the end of the magnet wire 100 that extends from the electrical device, which is provided as a winding for the electrical device. Connector 1, connected to the magnet wire 100, is connected to a mating connector, which is not shown in the figures. The mating connector to which connector 1 is connected is connected to other devices to which the electric device, such as an electric motor, which uses the magnet wire 100 as a winding, is electrically connected. By connecting connector 1 and the mating connector, the electric device, such as an electric motor, is connected to other devices.

[0029] Connector 1 comprises a housing 11, a contact 12, and a rubber member 13. The housing 11 is made of an insulating synthetic resin material and is configured so that a magnet wire 100 is inserted through it, and a contact 12 with the rubber member 13 attached is inserted into it. The contact 12 is made of a conductive metal material, for example, copper. The contact 12 is inserted into the housing 11 with the rubber member 13 attached and is held within the housing 11. The rubber member 13 is made of a rubber material and is configured to be attached to the contact 12. The rubber member 13, attached to the contact 12, is inserted into the housing 11 together with the contact 12 and is positioned inside the housing 11. Connector 1 is configured such that the magnet wire 100 is first inserted into the housing 11, and then the contact 12 with the rubber member 13 attached is inserted into the housing 11, thereby connecting the contact 12 and the magnet wire 100 by pressure contact.

[0030] The following describes the more detailed configuration of connector 1. In the following description, the front-to-back direction X1, the height direction X2, and the width direction X3 of connector 1 are defined as indicated by the double-ended arrows X1, X2, and X3 in Figures 1 to 6 and the drawings described later. Connector 1 has a roughly rectangular parallelepiped basic shape with mutually orthogonal directions for the front-to-back direction X1, the height direction X2, and the width direction X3. In connector 1, the contacts 12 and rubber members 13 are arranged inside the housing 11, and the roughly rectangular parallelepiped basic shape of the housing 11 constitutes the basic shape of connector 1.

[0031] The front-to-back direction X1 is configured to be parallel to the direction in which the magnet wire 100, which is inserted into the housing 11 of the connector 1, extends within the housing 11. That is, the front-to-back direction X1 is configured to be parallel to the direction in which the magnet wire 100 is inserted into the connector 1. Furthermore, the front-to-back direction X1 is parallel to the longitudinal direction of the magnet wire 100, which is the direction in which the magnet wire 100 extends after being inserted into the housing 11. The height direction X2 is configured to be perpendicular to the front-to-back direction X1 and parallel to the direction in which the contact 12 is inserted into the housing 11. Furthermore, the height direction X2 is configured to be parallel to the direction in which the mating connector (not shown) is fitted and connected to the connector 1 connected to the magnet wire 100. The width direction X3 is configured to be perpendicular to both the front-to-back direction X1 and the height direction X2.

The magnet wire 100 is held in the housing 11 when the contact 12 is inserted into the housing 11 with the magnet wire 100 inserted through it. Also, the rubber member 13 and the contact 12 are held in the housing 11 when the contact 12 with the rubber member 13 attached is inserted into the housing 11. Figures 7 and 8 show the housing 11 in a state where the magnet wire 100 has not been inserted and the contact 12 and rubber member 13 have not been inserted inside.

[0033] The housing 11 is provided in the shape of a rectangular tube with a basic outer shape that is roughly rectangular, and has an opening 21 that opens at one end in the height direction X2. The contact 12, to which the rubber member 13 is attached, is inserted into the inside of the housing 11 through the opening 21 and positioned inside the housing 11. When the connector 1, with the rubber member 13 and contact 12 positioned inside the housing 11 and the magnet wire 100 connected, is connected to a mating connector (not shown), the mating connector is fitted into the opening 21 of the housing 11 and connected to the connector 1.

[0035] The insertion grooves 22 are provided as slit-shaped grooves through which the magnet wire 100 is inserted, and are provided on both sides of the housing 11 in the front-rear direction X1. More specifically, the insertion grooves 22 are provided in one wall portion 24a and the other wall portion 24b of the outer wall of the rectangular tubular housing 11 in the front-rear direction X1. The insertion grooves 22 provided in the wall portions 24a and 24b extend in a slit shape along the height direction X2 and are provided to be open to the outside on the opening 21 side, which is one side in the height direction X2.

[0036] The magnet wire 100 is inserted into the insertion groove 22 from the side of the opening 21 that is open to the outside, along the height direction X2, and is inserted to the far end, which is on the opposite side of the opening 21 in the height direction X2. The magnet wire 100 is inserted into the insertion groove 22 provided in the wall portion 24a and also into the insertion groove 22 provided in the wall portion 24b. When the magnet wire 100 is inserted into the insertion groove 22 of the wall portion 24a and the insertion groove 22 of the wall portion 24b, it is positioned in the housing 11 with the housing 11 inserted along the front-rear direction X1.

[0037] Furthermore, referring to Figures 1 to 3, 7 and 8, the wall portion 24a, which is provided with the insertion groove 22, is provided with a wire support portion 25 that supports the magnet wire 100 which is inserted into the insertion groove 22 of the wall portion 24a and pulled out to the outside of the wall portion 24a. The wire support portion 25 is provided so as to protrude along the front-rear direction X1 toward the outside of the wall portion 24a from a position corresponding to the rear end of the insertion groove 22, which is opposite to the opening 21 side. The wire support portion 25 is provided with a support groove 25a in which a portion of the outer circumference of the magnet wire 100 pulled out from the end of the insertion groove 22 to the outside of the wall portion 24a is positioned. The portion of the magnet wire 100 that is pulled out from the insertion groove 22 of the wall portion 24a to the outside of the wall portion 24a is supported in a state where it is fitted into the support groove 25a of the wire support portion 25. The end of the magnet wire 100 that extends from the wall portion 24a is connected to an electrical device (not shown) such as an electric motor, and constitutes the winding of the electrical device. Note that the wall portion 24b does not have a wire support portion 25, and the end portion of the magnet wire 100 is inserted into the insertion groove 22 of the wall portion 24a.

[0038] Referring to Figures 3 to 8, the contact portion 23 is provided on the inside of the housing 11 and is provided as a portion that contacts the magnet wire 100 inserted through the insertion groove 22. The contact portion 23 is provided in the shape of a base on which the magnet wire 100 inserted through the insertion groove 22 is placed and contacts. In this embodiment, the contact portion 23 is provided as a first contact portion 23a, a second contact portion 23b, and a third contact portion 23c, which are arranged along the front-rear direction X1 on the inside of the housing 11. The first contact portion 23a, the second contact portion 23b, and the third contact portion 23c are all provided on the inside of the housing 11 on the side opposite to the opening 21 in the height direction X2, and are provided in the shape of a base on which the outer circumference of the magnet wire 100 inserted through the insertion groove 22 is placed and contacts.

[0039] The first contact portion 23a is located inside the housing 11, adjacent to and integrally with the wall portion 24a. Furthermore, the first contact portion 23a is located adjacent to the rear end of the insertion groove 22 of the wall portion 24a, on the opposite side from the opening 21, in the front-rear direction X1. The second contact portion 23b is located inside the housing 11, extending along the front-rear direction X1 between the wall portion 24a and the wall portion 24b. The second contact portion 23b is located inside the housing 11, and is positioned so as to rest on and contact the portion of the magnet wire 100 that extends along the front-rear direction X1 within the housing 11, which is inserted into the insertion groove 22 of the wall portion 24a and the insertion groove 22 of the wall portion 24b. The third contact portion 23c is located inside the housing 11, adjacent to and integrally with the wall portion 24b. Furthermore, the third contact portion 23c is provided adjacent to the rear end of the insertion groove 22 of the wall portion 24b, which is on the opposite side from the opening 21, in the front-rear direction X1.

[0040] (contact) Figure 9 shows the contact 12, where Figure 9(A) is a perspective view, Figure 9(B) is a front view, and Figure 9(C) is a side view.

The contact 12 is composed of a main body portion 26 having a first main body wall 26a and a second main body wall 26b that are arranged parallel to each other and integrally connected, and a mating side connection portion 27.

[0041] The mating connector portion 27 is provided as a spring contact portion that connects to the mating contact (not shown) of the mating connector (not shown) when connector 1 is connected to the mating connector (not shown). The mating connector portion 27 is integrally provided with the main body portion 26 and is provided as a leaf spring-like portion integrally connected to the second main body wall 26b of the main body portion 26. The mating connector portion 27 extends bent from the second main body wall 26b and is provided so as to extend cantilevered from the second main body wall 26b in the region between the first main body wall 26a and the second main body wall 26b, which is the inner region of the main body portion 26.

Both the first main body wall 26a and the second main body wall 26b are formed in a plate shape that extends along the height direction X2 and the width direction X3 when the contact 12 is placed inside the housing 11, and are formed to extend longer along the height direction X2 than along the width direction X3. The first main body wall 26a and the second main body wall 26b are arranged parallel to each other, and inside the housing 11, the first main body wall 26a is positioned on one side in the front-rear direction X1, and the second main body wall 26b is positioned on the other side in the front-rear direction X1. Inside the housing 11, the first main body wall 26a is positioned close to the wall portion 24a, and the second main body wall 26b is positioned close to the wall portion 24b.

[0043] Furthermore, the first main wall 26a and the second main wall 26b are integrally connected at one end in the height direction X2 by a pair of connecting portions 26c that extend along the front-rear direction X1. The pair of connecting portions 26c are provided on both sides in the width direction X3. One of the pair of connecting portions 26c connects the one end of the first main wall 26a and the second main wall 26b in the height direction X2 to the one end in the width direction X3. The other of the pair of connecting portions 26c connects the one end of the first main wall 26a and the second main wall 26b in the height direction X2 to the other end in the width direction X3.

[0044] Furthermore, the main body portion 26 is provided with slit blades 28. The slit blades 28 are provided in pairs on the main body portion 26, and are provided on the first main body wall 26a and the second main body wall 26b, respectively. Since the slit blades 28 are provided on the first main body wall 26a and the second main body wall 26b, when the contact 12 is placed inside the housing 11, they are arranged side by side in the front-rear direction X1 within the housing 11. Each slit blade 28 provided on the first main body wall 26a and the second main body wall 26b has a pair of blade portions 28a that extend substantially parallel to each other and face each other via a slit-shaped gap that extends along the height direction X2. The slit-shaped gap between the pair of blade portions 28a in each slit blade 28 is open to the outside of the slit blade 28 on one side in the height direction X2. When the contact 12 is placed inside the housing 11, the slit-shaped gap between the pair of blade portions 28a in each slit blade 28 is open to the outside of the slit blade 28 on the side opposite to the opening 21.

[0045] Each slit blade 28, provided on the first main body wall 26a and the second main body wall 26b of the main body portion 26, is configured to cut through the insulation 100b of the magnet wire 100 with its pair of blade portions 28a, and to bite into the core wire 100a of the magnet wire 100. The contact 12 is configured to be pressed against the magnet wire 100 by the pair of slit blades 28 cutting through the insulation 100b with its pair of blade portions 28a and biting into the core wire 100a, thereby making an electrical and mechanical connection to the magnet wire 100.

[0046] Furthermore, the contact 12 is configured such that each slit blade 28 bites into the magnet wire 100 when it is inserted into the housing 11 and installed. More specifically, first, with the magnet wire 100 inserted into the insertion groove 22 of the housing 11, the contact 12 with the rubber member 13 attached is inserted into the housing 11. When the contact 12 is inserted to the back of the opening 21 of the housing 11, each slit blade 28 of the main body 26, with the magnet wire 100 sandwiched between a pair of blades 28a, cuts through the insulation 100b of the sandwiched portion on both sides of the core wire 100a. Then, as the contact 12 is inserted to the back of the opening 21 of the housing 11, the slit blades 28 displace while cutting through the insulation 100b of the magnet wire 100, and further bite into the core wire 100a of the magnet wire 100. As the slit blade 28 bites into the magnet wire 100 and presses against the core wire 100a, the contact 12 becomes electrically and mechanically connected to the magnet wire 100.

[0047] Furthermore, the pair of slit blades 28 provided on the main body portion 26 are positioned in close proximity to the insertion grooves 22 provided in the walls 24a and 24b of the housing 11, respectively, when the contact 12 is inserted into the housing 11. Specifically, the main body portion 26 is configured such that the slit blade 28 provided on the first main body wall 26a is positioned in close proximity to the insertion groove 22 provided in the wall portion 24a, and the slit blade 28 provided on the second main body wall 26b is positioned in close proximity to the insertion groove 22 provided in the wall portion 24b. For this reason, the slit blade 28 provided on the first main body wall 26a is configured to bite into the magnet wire 100 in the area inside the housing 11 and in the area near the insertion groove 22 of the wall portion 24a. Furthermore, the slit blade 28 provided on the second main body wall 26b is configured to bite into the magnet wire 100 in the area inside the housing 11 and in the vicinity of the insertion groove 22 of the wall portion 24b.

[0048] Referring to Figures 4, 5, and 9, the main body portion 26 is provided with rubber mounting grooves 29. The rubber mounting grooves 29 are provided as grooves into which the mounting portion 31 of the rubber member 13, described later, is fitted and attached when the rubber member 13 is attached to the contact 12. Multiple rubber mounting grooves 29 are provided in each of the first main body wall 26a and the second main body wall 26b. In the first main body wall 26a, rubber mounting grooves 29 are provided on both sides in the width direction X3 and also side by side in the height direction X2, for a total of four grooves. In the second main body wall 26b, rubber mounting grooves 29 are also provided on both sides in the width direction X3 and also side by side in the height direction X2, for a total of four grooves. Furthermore, the four rubber mounting grooves 29 of the first main body wall 26a and the four rubber mounting grooves 29 of the second main body wall 26b are provided at corresponding positions in the height direction X2 and the width direction X3, respectively. In other words, the four rubber mounting grooves 29 of the first main body wall 26a and the four rubber mounting grooves 29 of the second main body wall 26b are located at opposing positions in the front-rear direction X1.

[0049] Referring to Figures 4, 5, and 9, the main body portion 26 is provided with press-fitting protrusions 30. The press-fitting protrusions 30 are provided as protruding parts that press-fit the contact 12 into the inside of the housing 11 when the contact 12 is inserted to the back of the opening 21 of the housing 11. Multiple press-fitting protrusions 30 are provided on the main body portion 26. In this embodiment, the press-fitting protrusions 30 are provided in pairs on the first main body wall 26a, on both sides in the width direction X3 on the first main body wall 26a. In addition, the press-fitting protrusions 30 are also provided in pairs on the second main body wall 26b, on both sides in the width direction X3 on the second main body wall 26b. Therefore, the main body portion 26 is provided with four press-fitting protrusions 30. When the contact 12 is inserted into the housing 11 and positioned inside the housing 11, the contact 12 is locked against the inner wall of the housing 11 by the press-fitting protrusions 30, and is in a press-fitted state. The contact 12, inserted into the housing 11, is held in place by being press-fitted into the inside of the housing 11.

Therefore, the second bridging portion 35b is configured to bridge the second cover wall portion 34b and the third cover wall portion 34c, which cover the slit blade 28 of the second main wall 26b of the contact 12 on both sides in the longitudinal direction of the magnet wire 100, respectively.

[0069] (Connection operation between connector and magnetic wire) Next, the connection operation when the connector 1 and the magnet wire 100 are connected will be described. Figure 15 is a diagram illustrating the operation when connecting the magnet wire 100 and the connector 1. Figure 15(A) shows the state before the magnet wire 100 is inserted into the insertion groove 22 of the housing 11. Figure 15(B) shows the state before the contact 12 with the rubber member 13 attached is inserted into the housing 11. Figure 15(C) shows the state after the contact 12 with the rubber member 13 attached has been inserted into the housing 11. The connection operation between the connector 1 and the magnet wire 100 will be described below with reference to Figures 1 to 14 mentioned above, as well as Figure 15.

[0070] When the connector 1 and the magnet wire 100 are connected, the magnet wire 100 is first positioned in the housing 11 with the magnet wire 100 inserted through it. At this time, as shown in Figure 15(A), the magnet wire 100 is positioned above the insertion groove 22 in the housing 11. Then, the magnet wire 100 is moved along the direction indicated by arrow Y1 in Figure 15(A) and inserted into the insertion groove 22. Once the magnet wire 100 is inserted into the insertion groove 22, as shown in Figure 15(B), the magnet wire 100 is in a state where it is inserted into the insertion groove 22. The magnet wire 100 inserted into the insertion groove 22 is supported on the inside of the housing 11 by the first contact portion 23a, the second contact portion 23b, and the third contact portion 23c.

[0071] Before the contact 12 is inserted into the housing 11, the rubber member 13 is attached to it. When the rubber member 13 is attached to the contact 12, the first mounting portion 31a and the second mounting portion 31b, which extend in a strip shape in the circumferential direction, are each stretched to expand in diameter and positioned along the outer circumference of the main body portion 26 of the contact 12. Then, the expanded first mounting portion 31a and the second mounting portion 31b are elastically restored to their original size and contracted in diameter, so that the first mounting portion 31a and the second mounting portion 31b are fitted into the rubber mounting grooves 29 of the main body portion 26 and attached to the outer circumference of the main body portion 26. With the first mounting portion 31a and the second mounting portion 31b attached to the main body portion 26, the rubber member 13 is attached to the outer circumference of the contact 12, as shown in Figures 12 to 14 and Figure 15(B). Furthermore, when the rubber member 13 is attached to the contact 12, the first cover wall portion 34a and the second cover wall portion 34b, which are provided with slit grooves 33, are positioned adjacent to the slit blades 28 of the first main body wall 26a on both sides in the front-rear direction X1. The second cover wall portion 34b and the third cover wall portion 34c, which are provided with slit grooves 33, are positioned adjacent to the slit blades 28 of the second main body wall 26b on both sides in the front-rear direction X1.

[0072] When the rubber member 13 is attached to the contact 12 and the magnet wire 100 is inserted into the insertion groove 22 of the housing 11, the contact 12 with the rubber member 13 attached is then inserted into the housing 11. At this time, as shown in Figure 15(B), the contact 12 with the rubber member 13 attached is positioned above the housing 11. Then, the contact 12 with the rubber member 13 attached is moved along the direction indicated by the arrow Y2 in Figure 15(B) and inserted into the opening 21 of the housing 11. Then, as shown in Figure 15(C), the contact 12 with the rubber member 13 attached is inserted into the interior of the housing 11 from the opening 21 and positioned inside the housing 11.

[0073] As the contact 12 is inserted into the housing 11 through the opening 21, as shown in Figure 5, each slit blade 28 of the main body 26 sandwiches the magnet wire 100, supported by the contact portion 23, between the pair of blades 28a, and cuts through the insulation 100b on both sides of the core wire 100a. As the contact 12 is inserted further into the opening 21 of the housing 11, the slit blades 28 displace the magnet wire 100 while cutting through the insulation 100b, and further bite into the core wire 100a of the magnet wire 100. As the slit blades 28 bite into the magnet wire 100 and press against the core wire 100a, the contact 12 becomes electrically and mechanically connected to the magnet wire 100. Furthermore, when the contact 12 with the rubber member 13 attached is inserted into the housing 11 and the contact 12 and the magnet wire 100 are pressed together, as shown in Figures 3 to 6, the area where the contact 12 and the magnet wire 100 are pressed together is covered by the edge of the slit groove 33 of the cover wall portion 34 of the slit blade cover portion 32 of the rubber member 13 and the contact portion 23 of the housing 11. Note that the connection operation between the connector 1 and the magnet wire 100 is completed when the contact 12 with the rubber member 13 attached is inserted into the housing 11 and the contact 12 and the magnet wire 100 are pressed together.

[0074] (Operation and effects of this embodiment) In this embodiment of connector 1, the contact 12 with the rubber member 13 attached is inserted into the housing 11, and the magnet wire 100 inserted into the insertion groove 22 of the housing 11 is also inserted into the slit blade 28 of the contact 12. As a result, the slit blade 28 cuts through the coating 100b of the magnet wire 100 and bites into it, pressing it against the magnet wire 100. The contact 12 and the magnet wire 100 are pressed together, and the connector 1 is connected to the magnet wire 100.

[0075] Furthermore, according to connector 1, the rubber member 13, which is attached to the contact 12 and inserted into the housing 11 together with the contact 12, is provided with a slit blade cover portion 32. When the magnet wire 100 is inserted through the slit groove 33 of the slit blade cover portion 32, which opens corresponding to the insertion groove 22 of the housing 11, both sides of the slit blade 28 are covered by the slit blade cover portion 32. Moreover, when the contact 12 with the rubber member 13 attached is inserted into the housing 11 and the contact 12 and the magnet wire 100 are pressed together, the area where the contact 12 and the magnet wire 100 are pressed together is covered by the edge of the slit groove 33 of the slit blade cover portion 32 and the contact portion 23 of the housing 11.

[0076] Furthermore, with connector 1, the areas of the contact blade 28 of contact 12 and the magnet wire 100 pressed against the slit blade 28 are covered by the rubber member 13 and the housing 11, shielding them from exposure to the outside. In other words, the areas of the contact 12 and the magnet wire 100 pressed against each other are shielded by the rubber member 13 and the housing 11, preventing them from being exposed to the outside through the insertion groove 22 of the housing 11. Therefore, even when connector 1 is used in a high-humidity environment or in an environment where saltwater may be sprayed, the pressed-together portions of the contact blade 28 of contact 12 and the magnet wire 100 are covered by the rubber member 13 and the housing 11, shielding them from the outside. This prevents electrolytic corrosion from occurring in the pressed-together portions of contact 12 and the magnet wire 100.

[0077] Furthermore, as described above, with connector 1, the pressed-together portion of the contact 12 and the magnet wire 100 is covered by the rubber member 13 and the housing 11, shielding it from the outside and preventing electrolytic corrosion from occurring at the pressed-together portion of the contact 12 and the magnet wire 100. Therefore, there is no need for a secondary treatment to embed the pressed-together portion of the contact 12 and the magnet wire 100 in resin to prevent electrolytic corrosion. By eliminating the need for such a secondary treatment, the increase in labor during the installation of connector 1 can be suppressed, and the increase in installation costs for connector 1 can also be suppressed.

[0078] Therefore, according to this embodiment, it is possible to provide a connector 1 that can prevent electrolytic corrosion from occurring in the pressed-together portion of the contact 12 and the magnet wire 100, and eliminate the need for a secondary treatment in which the pressed-together portion of the contact 12 and the magnet wire 100 is embedded in resin to prevent electrolytic corrosion.

[0079] Furthermore, with connector 1, when the magnet wire 100 is inserted into the insertion groove 22 of the housing 11, the magnet wire 100 can be brought into contact with the contact portion 23 of the housing 11. In this state, the contact 12 with the rubber member 13 attached is inserted into the housing 11, and the contact 12 and the magnet wire 100 are pressed together, and the pressed-together portion of the contact 12 and the magnet wire 100 can be covered by the slit blade cover portion 32 of the rubber member 13 and the contact portion 23 of the housing 11. For this reason, the housing 11 into which the contact 12 with the rubber member 13 attached is inserted can be configured as an integrated housing 11 with the insertion groove 22 and the contact portion 23 provided. Thus, the housing 11 in connector 1, which can cover the pressed-together portion of the contact 12 and the magnet wire 100 with the rubber member 13 and the housing 11 to shield it from the outside, can be configured as a single component.

[0080] Furthermore, according to connector 1, a slit blade cover portion 32 can be formed that covers the pressed-together portion of the contact 12 and the magnet wire 100 together with the housing 11, shielding it from the outside, with a simple structure in which slit grooves 33 are provided in each of the cover wall portions 34 that cover both sides of the slit blade 28.

[0081] Furthermore, with connector 1, the cover wall portions 34 (first cover wall portion 34a, second cover wall portion 34b, third cover wall portion 34c) that shield the pressed-together portion of the contact 12 and the magnet wire 100 from the outside on both sides of the slit blade 28 can be integrated with a simple structure consisting only of a bridging portion 35 (first bridging portion 35a, second bridging portion 35b). Moreover, since the bridging portion 35 that integrates the cover wall portions 34 on both sides of the slit blade 28 is provided so as to penetrate between the slit blades 28, the cover wall portions 34 on both sides of the slit blade 28 can be integrated with a compact structure that can be provided in a small space.

[0082] Furthermore, according to connector 1, when attaching the rubber member 13 to the contact 12, the mounting portion 31 (first mounting portion 31a, second mounting portion 31b) of the rubber member 13, which extends in a strip shape in the circumferential direction, is temporarily stretched to expand its diameter and positioned along the outer circumference of the contact 12. After that, the mounting portion 31 is elastically restored, allowing the rubber member 13 to be easily attached to the outer circumference of the contact 12. In addition, since the rubber member 13 is attached to the contact 12 with the mounting portion 31 extending in the circumferential direction relative to the outer circumference of the contact 12, the rubber member 13 attached to the contact 12 is less likely to come off. As a result, the rubber member 13 can be attached to the contact 12 in a stable state that is less likely to come off.

[0083] [Second Embodiment] Next, a second embodiment of the present invention will be described. Figure 16 is a plan view of the connector 2 according to the second embodiment of the present invention, showing it connected to the magnet wire 100. Figure 17 shows the connector 2 in an disassembled state. Figure 18(A) is a front view of the contact 12 in the connector 2, and Figure 18(B) is a front view of the rubber member 13 in the connector 2. Figures 19 to 21 are cross-sectional views showing the connector 2 connected to the magnet wire 100. Figure 19 is a cross-sectional view of the connector 2 at the position indicated by the arrow KK in Figure 16. Figure 20 is a cross-sectional view of the connector 2 at the position indicated by the arrow LL in Figure 16. Figure 21 is a cross-sectional view of the connector 2 at the position indicated by the arrow MM in Figure 16. The connector 2 of the second embodiment is configured similarly to the connector 1 of the first embodiment, except for some configurations. In the following description of the second embodiment, the differences from the first embodiment described above will be explained, and for configurations similar to or corresponding to the first embodiment, the same reference numerals will be used in the drawings, or the same reference numerals will be used to omit redundant explanations.

[0084] Referring to Figures 16 to 21, the connector 2 of the second embodiment is configured similarly to the connector 1 of the first embodiment, comprising a housing 11, a contact 12, and a rubber member 13. The housing 11 is provided with a slit-shaped insertion groove 22 through which the magnet wire 100 is inserted, and a contact portion 23 that abuts against the magnet wire 100 inserted into the insertion groove 22. The contact 12 has a slit blade 28 that cuts through the coating 100b of the magnet wire 100 and bites into the magnet wire 100, and is inserted into the housing 11 and pressed against the magnet wire 100 to connect it. The rubber member 13 is provided to be attached to the contact 12. The rubber member 13 covers the slit blade 28 of the contact 12 on both sides in the longitudinal direction of the magnet wire 100, and has a slit blade cover portion 32 that has a slit groove 33 that opens in a slit shape at a position corresponding to the insertion groove 22 through which the magnet wire 100 is inserted. Furthermore, the slit blade cover portion 32 has cover wall portions 34 that cover the slit blade 28 on both sides in the longitudinal direction of the magnet wire 100, and each of the cover wall portions 34 is provided with a slit groove 33. The connector 2 is configured such that, with the contact 12 fitted with the rubber member 13 inserted into the housing 11 and the contact 12 and the magnet wire 100 pressed together, the area where the contact 12 and the magnet wire 100 are pressed together is covered by the edge of the slit groove 33 of the slit blade cover portion 32 and the contact portion 23 of the housing 11. However, the connector 2 differs from the connector 1 of the first embodiment in the configuration of the housing 11. Also, the connector 2 differs from the first embodiment in that the contact 12 fitted with the rubber member 13 is inserted into the housing 11 in the opposite orientation to that of the connector 1 of the first embodiment.

[0085] Referring to Figures 16 to 21, the housing 11 is comprised of a first housing 41 and a second housing 42 provided separately from the first housing 41. The first housing 41 is provided with an insertion groove 22 through which the magnet wire 100 is inserted, and is configured to accommodate a contact 12 with a rubber member 13 attached.

[0086] The contact 12 with the rubber member 13 attached is inserted into the first housing 41 from the opening 21 of the first housing 41 along the height direction X1. However, in connector 2, the contact 12 with the rubber member 13 attached is inserted into the first housing 41 in a position opposite to that of the first embodiment in the height direction X2. Specifically, the contact 12 with the rubber member 13 attached is inserted into the opening 21 of the first housing 41 from the end opposite to the side in the height direction X2 where the slit blade 28 is open to the outside. That is, the contact 12 with the rubber member 13 attached is inserted into the first housing 41 in a position where the slit-shaped gap between the pair of blade portions 28a of each slit blade 28 is open to the opening 21 of the first housing 41. Therefore, when the contact 12 is inserted into the first housing 41 and positioned inside the first housing 41, the slit-shaped gap between the pair of blade portions 28a of each slit blade 28 is open to the outside on the opening 21 side.

[0087] Furthermore, the first housing 41 is configured to connect to a mating connector (not shown) at the end opposite to the end on which the opening 21 in the height direction X2 opens. The first housing 41 is provided with a connection opening (not shown) at the end opposite to the opening 21 in the height direction X2 into which the mating contact (not shown) of the mating connector is inserted. When connecting the connector 2 and the mating connector, the mating contact of the mating connector is inserted into the connection opening of the first housing 41 and makes contact with the mating connection portion 27 of the contact 12 inside the first housing 41, thereby making a connection. The connector 2 and the mating connector are electrically connected when the mating connection portion 27 of the connector 2 and the mating contact of the mating connector make contact and make a connection.

[0088] The second housing 42 is provided as a separate housing element from the first housing 41. The second housing 42 is configured to be inserted and fitted into the slit blades 28 of the contact 12 when it is inserted into the first housing 41. That is, the second housing 42 is inserted into the opening 21 of the first housing 41 when the contact 12 with the rubber member 13 attached is inserted into the first housing 41 and positioned inside the first housing 41, and then inserted and fitted into the slit blades 28 of the contact 12 inside the first housing 41. The second housing 42 is inserted and fitted into both of the pair of slit blades 28 of the contact 12.

[0089] Furthermore, the second housing 42 is provided with a contact portion 23 that abuts against the magnet wire 100 inserted through the insertion groove 22 of the first housing 41. In the second housing 42, the contact portion 23 is provided as a portion of one end in the height direction X2. The second housing 42 is configured such that, when fitted into the slit blade 28, the contact portion 23 abuts against the magnet wire 100 inserted through the insertion groove 22 of the first housing 41 and the slit groove 33 of the rubber member 13.

[0090] When the second housing 42 is inserted into and fitted onto the slit blade 28 of the contact 12, first the contact 12 with the rubber member 13 attached is inserted into and positioned within the first housing 41. Then, the magnet wire 100 is inserted into the insertion groove 22 of the first housing 41, the slit blade 28 of the contact 12, and the slit groove 33 of the rubber member 13. In this state, the second housing 42 is inserted into and fitted onto the slit blade 28 of the contact 12 from the end where the contact portion 23 is provided. As the second housing 42 is inserted into and fitted onto the slit blade 28, the contact portion 23 comes into contact with the magnet wire 100 that has been inserted into the insertion groove 22 of the first housing 41 and the slit groove 33 of the rubber member 13.

[0091] When the second housing 42 is fitted onto the slit blade 28 of the contact 12 and in contact with the magnet wire 100 at the contact portion 23, the slit blade 28 of the contact 12 and the magnet wire 100 are pressed against each other. In this state, the area where the slit blade 28 of the first main body wall 26a of the contact 12 and the magnet wire 100 are pressed against each other is covered from the outside of the main body 26 by the edge of the slit groove 33 of the first cover wall 34a and the contact portion 23 of the second housing 42. Furthermore, the area where the slit blade 28 of the first main body wall 26a and the magnet wire 100 are pressed against each other is also covered from the inside of the main body 26 by the edge of the slit groove 33 of the second cover wall 34b and the contact portion 23 of the second housing 42. Furthermore, the area in which the slit blade 28 of the second main body wall 26b of the contact 12 and the magnet wire 100 are pressed together is covered from the inside of the main body 26 by the edge of the slit groove 33 of the second cover wall 34b and the contact portion 23 of the second housing 42. In addition, the area in which the slit blade 28 of the second main body wall 26b and the magnet wire 100 are pressed together is also covered from the outside of the main body 26 by the edge of the slit groove 33 of the third cover wall 34c and the contact portion 23 of the second housing 42. Thus, the connector 2 is configured such that, when the contact 12 with the rubber member 13 attached is inserted into the housing 11 and the contact 12 and the magnet wire 100 are pressed together, the area in which the contact 12 and the magnet wire 100 are pressed together is covered by the edge of the slit groove 33 of the cover wall 34 of the slit blade cover portion 32 of the rubber member 13 and the contact portion 23 of the second housing 42.

[0092] Alternatively, the magnet wire 100 may be inserted through the slit blade 28 of the contact 12 and pressed against it before the contact 12 with the rubber member 13 attached is inserted into the first housing 41. In this case, the contact 12 with the rubber member 13 attached and the magnet wire 100 pressed against it is inserted into the first housing 41. Then, with the contact 12 with the rubber member 13 attached and the magnet wire 100 pressed against it positioned inside the first housing 41, the second housing 42 is inserted and fitted onto the slit blade 28 of the contact 12.

[0093] Next, the connection operation when the connector 2 and the magnet wire 100 are connected will be described. Figure 22 is a cross-sectional view of the connector 2 to illustrate the operation when connecting the connector 2 and the magnet wire 100. Figure 22(A) shows the state in which the contact 12 with the rubber member 13 attached is inserted into the first housing 41. Figure 22(B) shows the state in which the magnet wire 100 is inserted through the insertion groove 22 of the first housing 41 and also inserted into the slit blade 28 of the contact 12. Figure 22(C) shows the state in which the second housing 42 is inserted into the slit blade 28 of the contact 12. Note that Figure 22 shows a cross-sectional view corresponding to the cross-section at the position indicated by the arrow KK in Figure 16. The connection operation between the connector 2 and the magnet wire 100 will be described below with reference to Figures 16 to 21 mentioned above, as well as Figure 22.

[0094] When the connector 2 and the magnet wire 100 are connected, the rubber member 13 is first attached to the contact 12. When the rubber member 13 is attached to the contact 12, the first mounting portion 31a and the second mounting portion 31b of the rubber member 13 are fitted into the rubber mounting groove 29 of the main body portion 26 and attached to the outer circumference of the main body portion 26. With the first mounting portion 31a and the second mounting portion 31b attached to the main body portion 26, the rubber member 13 is attached to the outer circumference of the contact 12, as shown in Figure 17. In addition, with the rubber member 13 attached to the contact 12, the first cover wall portion 34a and the second cover wall portion 34b, which are provided with slit grooves 33, are positioned adjacent to the slit blade 28 of the first main body wall 26a on both sides in the front-rear direction X1. Furthermore, the second cover wall portion 34b and the third cover wall portion 34c, which are provided with slit grooves 33, are arranged adjacent to the slit blades 28 of the second main body wall 26b on both sides in the front-rear direction X1.

[0095] Once the rubber member 13 is attached to the contact 12, the contact 12 with the rubber member 13 attached is then inserted into the first housing 41. The contact 12 with the rubber member 13 attached is inserted into the first housing 41 from the opening 21. At this time, the contact 12 with the rubber member 13 attached is inserted into the opening 21 of the first housing 41 from the end opposite to the side where the slit blade 28 in the height direction X2 is open to the outside. Once the contact 12 with the rubber member 13 attached is inserted into the first housing 41 and positioned inside the first housing 41, as shown in Figure 22(A), the slit-shaped gap between the pair of blade portions 28a of each slit blade 28 of the contact 12 becomes open to the outside on the opening 21 side.

[0096] When the contact 12 with the rubber member 13 attached is inserted into the first housing 41, the magnet wire 100 is then inserted and pushed into the insertion groove 22 of the first housing 41, the slit blade 28 of the contact 12, and the slit groove 33 of the rubber member 13, as shown in Figure 22(B). This results in the magnet wire 100 being inserted into the insertion groove 22 of the first housing 41, the slit blade 28 of the contact 12, and the slit groove 33 of the rubber member 13. Furthermore, as the magnet wire 100 is pushed and inserted into the slit blade 28 of the contact 12, the insulation 100b of the magnet wire 100, sandwiched between the pair of blade portions 28a of the slit blade 28, is cut through on both sides of the core wire 100a. As the magnet wire 100 is inserted further into the slit blade 28, the slit blade 28 that has cut through the insulation 100b of the magnet wire 100 bites into the core wire 100a of the magnet wire 100. As the slit blade 28 bites into the magnet wire 100 and presses against the core wire 100a, the contact 12 becomes electrically and mechanically connected to the magnet wire 100.

[0097] When the magnet wire 100 is inserted through the insertion groove 22 of the first housing 41, the slit blade 28 of the contact 12, and the slit groove 33 of the rubber member 13, and the contact 12 and the magnet wire 100 are pressed together, the second housing 42 is then inserted and fitted onto the slit blade 28, as shown in Figure 22(C). As the second housing 42 is inserted and fitted onto the slit blade 28, the contact portion 23 comes into contact with the magnet wire 100 which is inserted through the insertion groove 22 of the first housing 41 and the slit groove 33 of the rubber member 13. When the second housing 42 is fitted onto the slit blade 28 pressed against the magnet wire 100, as shown in Figures 19 to 21 and 22(C), the area where the contact 12 and the magnet wire 100 are pressed against each other is covered by the edge of the slit groove 33 of the cover wall portion 34 of the slit blade cover portion 32 of the rubber member 13 and the contact portion 23 of the second housing 42. The connection operation between the connector 2 and the magnet wire 100 is completed when the second housing 42 is fitted onto the slit blade 28 pressed against the magnet wire 100.

[0098] According to the connector 2 of the second embodiment described above, the contact 12 with the rubber member 13 attached is inserted into the first housing 41, and the magnet wire 100 inserted into the insertion groove 22 of the first housing 41 is also inserted into the slit blade 28 of the contact 12. As a result, the slit blade 28 cuts through the coating 100b of the magnet wire 100 and bites into it, pressing it against the magnet wire 100. The contact 12 and the magnet wire 100 are pressed against each other, and the connector 2 is connected to the magnet wire 100.

[0099] Furthermore, according to connector 2, the rubber member 13, which is attached to the contact 12 and inserted into the first housing 41 together with the contact 12, is provided with a slit blade cover portion 32. With the magnet wire 100 inserted through the slit groove 33 of the slit blade cover portion 32, which opens corresponding to the insertion groove 22 of the first housing 41, both sides of the slit blade 28 are covered by the slit blade cover portion 32. Moreover, when the contact 12 with the rubber member 13 attached is inserted into the first housing 41 and the contact 12 and the magnet wire 100 are pressed together, the area where the contact 12 and the magnet wire 100 are pressed together is covered by the edge of the slit groove 33 of the slit blade cover portion 32 and the contact portion 23 of the second housing 42.

[0100] Furthermore, with connector 2, the areas of the contact blade 28 of the contact 12 and the magnet wire 100 pressed against the slit blade 28 are covered by the rubber member 13 and the second housing 42 of the housing 11, shielding them from exposure to the outside. In other words, the areas of the contact 12 and the magnet wire 100 pressed against each other are shielded by the rubber member 13 and the second housing 42, preventing them from being exposed to the outside through the insertion groove 22 of the first housing 41. Therefore, even when connector 2 is used in a high-humidity environment or in an environment where saltwater may be sprayed, the pressed-together portions of the contact blade 28 of the contact 12 and the magnet wire 100 are covered by the rubber member 13 and the second housing 42, shielding them from the outside. This prevents electrolytic corrosion from occurring in the pressed-together portions of the contact 12 and the magnet wire 100.

[0101] Furthermore, as described above, with connector 2, the pressed-together portion of the contact 12 and the magnet wire 100 is covered by the rubber member 13 and the second housing 42 of the housing 11, shielding it from the outside and preventing electrolytic corrosion from occurring at the pressed-together portion of the contact 12 and the magnet wire 100. Therefore, there is no need for a secondary treatment to embed the pressed-together portion of the contact 12 and the magnet wire 100 in resin to prevent electrolytic corrosion. By eliminating the need for such a secondary treatment, the increase in labor during the installation of connector 2 can be suppressed, and the increase in installation costs for connector 2 can also be suppressed.

[0102] Therefore, according to the second embodiment, it is possible to provide a connector 2 that can prevent electrolytic corrosion from occurring in the pressed-together portion of the contact 12 and the magnet wire 100, and eliminate the need for a secondary treatment in which the pressed-together portion of the contact 12 and the magnet wire 100 is embedded in resin to prevent electrolytic corrosion.

[0103] Furthermore, according to the connector 2 of the second embodiment, the contact 12 with the rubber member 13 attached is inserted into the first housing 41, and the magnet wire 100 is inserted through the insertion groove 22 of the first housing 41 and the slit groove 33 of the rubber member 13, and the magnet wire 100 is pressed against the slit blade 28 of the contact 12. Then, the second housing 42, which is separate from the first housing 41 and has a contact portion 23, is inserted into the slit blade 28 and fitted into place, so that the contact portion 23 comes into contact with the magnet wire 100 inserted through the insertion groove 22 of the first housing 41 and the slit groove 33 of the rubber member 13. As a result, the area where the contact 12 and the magnet wire 100 are pressed against is covered by the edge of the slit groove 33 of the slit blade cover portion 32 and the contact portion 23 of the second housing 42. As a result, the pressed-together portion of the contact 12's slit blade 28 and the magnet wire 100 is covered by the rubber member 13 and the second housing 42, shielding it from exposure to the outside. Therefore, according to the second embodiment, even in the case of a connector 2 in which the operation of inserting the contact 12 into the first housing 41 and pressing the magnet wire 100 against the contact 12 is required, and then inserting and fitting the second housing 42 onto the slit blade 28 of the contact 12, the pressed-together portion of the contact 12 and the magnet wire 100 can be covered by the rubber member 13 and the housing 11, shielding it from exposure to the outside.
