Description

Method for manufacturing electric connector, electric connector and electronic device

The present invention is a divisional application of the invention with application number 201911017052.9 entitled "electrical connector and electronic device".

Technical Field

The present invention relates generally to an electrical connector and an electronic apparatus including the same, and more particularly, to an electrical connector which can be attached to a case of an electronic apparatus through a fitting hole formed in the case of the electronic apparatus and which can liquid-tightly seal a space between the electrical connector and the electronic apparatus with a waterproof sealing member, and an electronic apparatus including the same.

Background

Conventionally, an electrical connector is used to electrically connect an electronic device and another electronic device. In order to obtain electrical connection between an electronic device and another electronic device, two types of electrical connectors, a receptacle connector that is mounted on a circuit board provided in a housing of the electronic device and has an insertion opening exposed to the outside of the electronic device through a through hole provided in the housing of the electronic device, and a plug connector that is inserted into the insertion opening of the receptacle connector, are used in combination.

As such an electronic connector, a usb (universal Serial bus) connector and the like are widely used. For example, patent document 1 discloses a receptacle connector that is mounted on a circuit board provided in a casing of an electronic device (for example, a personal computer, a game machine, a mobile phone, or a smart phone), and an insertion port of the receptacle connector is exposed to the outside of the electronic device through a through hole provided in the casing of the electronic device. By inserting the corresponding plug connector into the insertion opening of the receptacle connector exposed to the outside of the electronic device, electrical connection between the electronic device and another electronic device can be provided.

In addition, the above-described receptacle connector is widely used also in portable devices such as mobile phones and smart phones. Assume a case where a user rains and the portable device gets wet with water, and a case where the portable device is inadvertently dropped into water while the user carries the portable device with him or her. In order to prevent water from entering the inside of the housing of the electronic device through the gap between the receptacle connector and the housing of the electronic device, an electrical connector 800 with a waterproof function as shown in fig. 1 and 2 is known, which includes a waterproof sealing member (a gasket or the like made of an elastic material) 820 provided at the front end portion of the outer periphery of a housing 810 (see, for example, patent document 2).

As shown in fig. 2, the electrical connector 800 is inserted into a fitting hole 910 formed in a housing 900 of an electronic device and attached to the housing 900 of the electronic device. When the electrical connector 800 is attached to the case 900 of the electronic device, a gap between the electrical connector 800 and the case 900 of the electronic device is liquid-tightly sealed by a waterproof sealing member 820 provided at a front end portion of an outer periphery of the housing 810 of the electrical connector 800. With this configuration, water is prevented from entering the inside of the case 900 of the electronic apparatus through the gap between the electrical connector 800 and the case 900 of the electronic apparatus.

However, the waterproof sealing member 820 is made of an elastic material such as a soft resin material, a silicon material, or rubber, and thus has low strength. Therefore, when the electrical connector 800 is inserted into the fitting hole 910 of the housing 900 of the electronic device, the entire outer peripheral region of the waterproof sealing member 820 is inserted while being in contact with the entire inner side surface region of the fitting hole 910 of the housing 900 of the electronic device, but in this case, it is difficult to equalize the frictional force between the waterproof sealing member 820 and the inner side surface of the fitting hole 910 due to variations in the insertion angle or the like, and hence, wrinkles, twists, or curls of the waterproof sealing member 820 are likely to occur. If such wrinkles, twists, or curls of the waterproof sealing member 820 are generated, the waterproof function of the electrical connector 800 cannot be provided.

In response to such a problem, a method (for example, LIM) of directly Molding the waterproof sealing member 820 on the outer periphery of the housing 810 of the electrical connector 800 is sometimes used. However, such a method increases the manufacturing time of the electrical connector 800, and as a result, the productivity of the electrical connector 800 deteriorates, and the manufacturing cost of the electrical connector 800 increases.

Fig. 17 is a vertical cross-sectional view showing a state in which the electrical connector shown in fig. 3 is attached to a housing of an electronic apparatus.

As shown in fig. 17, the electrical connector 1 according to the first embodiment of the present invention shown in fig. 3 to 6 is mounted as a receptacle connector on a circuit board (not shown) provided in a housing 100 of an electronic device. The electrical connector 1 is inserted into a fitting hole 110 formed in the housing 100 of the electronic device from the inside of the housing 100 of the electronic device and having a shape corresponding to the outer shape of the electrical connector 1, and is attached to the housing 100 of the electronic device.

In a state where the electrical connector 1 is attached to the housing 100 of the electronic device, the insertion opening 211 on the front end side of the housing 2 of the electrical connector 1 is exposed to the outside through the fitting hole 110 of the housing 100 of the electronic device. The electrical connector 1 is configured to provide electrical connection between the electrical connector 1 and an object-side connector when the object-side connector (plug connector) is inserted into the insertion port 211 of the electrical connector 1 exposed to the outside.

As shown in fig. 3 to 6, the electrical connector 1 includes: a metal housing 2 including a cylindrical main body portion 21 and an annular engaging portion 22 formed at a distal end of an outer periphery of the main body portion 21 so as to protrude outward from the main body portion 21; a shield member 3 provided so as to cover the outer periphery of the body portion 21 of the housing 2 except for a front end portion 213 (see fig. 7) of the outer periphery of the body portion 21 of the housing 2; an inner structure 4 including a plurality of contacts 41 that contact a plurality of contacts of an object-side connector, a ground plate 42 that is arranged parallel to a plane in which the plurality of contacts 41 are arranged, and an insulator 43 that holds the plurality of contacts 41 and the ground plate 42; and a waterproof sealing member 5 which is provided so as to cover the distal end portion 213 of the outer periphery of the body portion 21 of the housing 2 which is not covered with the shield member 3, and which is held between the locking portion 22 of the housing 2 and the end surface 311 on the distal end side of the shield member 3.

The outer case 2 is a cylindrical member made of a metal material, and covers the inner structure 4 from the outside. The housing 2 accommodates the internal structure 4 therein in a state of covering the internal structure 4 except for the distal end side and the proximal end side in the fitting direction (Z-axis direction in the drawings) of the electrical connector 1. As shown in fig. 5 and 6, the housing 2 includes: a cylindrical body portion 21; an annular locking portion 22 formed to protrude outward from a front end of an outer periphery of the body portion 21; an engagement recess 23 formed in a region adjacent to a proximal end of the annular locking portion 22 at a distal end 213 of the outer periphery of the body portion 21; and a pair of notches 24 for receiving the pair of housing pressing portions 33 of the shield member 3 in a state where the electrical connector 1 is assembled.

The main body 21 of the housing 2 has a flat cylindrical shape as shown in fig. 5. The internal structure 4 is housed in a space defined by the cylindrical inner surface of the main body 21. An insertion port 211 for receiving the target-side connector is formed on the distal end side of the main body 21. On the other hand, a base end opening 212 is formed on the base end side of the body portion 21, and the base end opening 212 is used to guide the plurality of contacts 41 and the ground plate 42 of the internal structure 4 housed in the housing 2 to the circuit board of the electronic device.

In the assembled state of the electrical connector 1, the internal structure 4 is housed inside the main body 21. The plurality of contacts 41 and the ground plate 42 of the inner structure 4 extend from the base-end opening 212 of the main body 21 toward the circuit board of the electronic device, and the plurality of contacts 41 and the ground plate 42 of the inner structure 4 are connected to the circuit board of the electronic device via the board connection portions 413 and 422 (see fig. 10 to 12), whereby the electrical connector 1 is mounted on the circuit board of the electronic device.

In the assembled state of the electrical connector 1, if the subject-side connector is inserted into the insertion opening 211 of the housing 2 from the distal end side, the plurality of contacts of the subject-side connector come into contact with the plurality of contacts 41 of the internal structure 4 housed inside the main body portion 21, respectively, whereby the electrical connection between the subject-side connector inserted from the distal end side and the electrical connector 1 can be provided. Then, the ground terminal of the object-side connector is brought into contact with the ground plate 42, whereby the ground potentials of the object-side connector and the electrical connector 1 are equalized.

The locking portion 22 of the housing 2 has a function of locking the waterproof seal member 5 provided to cover the distal end portion 213 of the outer periphery of the body portion 21 from the distal end side. The locking portion 22 is an annular portion formed to protrude outward from the front end of the outer periphery of the body portion 21. Therefore, in the housing 2, the outer diameter of the portion where the locking portion 22 is formed (the outer shape of the locking portion 22) is larger than the outer shape of the portion where the locking portion 22 is not formed (the outer shape of the body portion 21).

The height of the locking portion 22 is preferably 0.05 to 0.5mm, and more preferably 0.1 to 0.3 mm. If the height of the locking portion 22 is lower than the lower limit value, the waterproof sealing member 5 may not be locked reliably from the distal end side, and the waterproof sealing member 5 may not be prevented from being wrinkled, twisted, or curled when the electrical connector 1 is inserted into the fitting hole 110 of the housing 100 of the electronic device. On the other hand, if the height of the locking portion 22 exceeds the upper limit value, the gap between the electrical connector 1 and the housing 100 of the electronic device when the electrical connector 1 is inserted into the housing 100 of the electronic device becomes large, and there is a case where the waterproof function provided by the electrical connector 1 cannot be sufficiently provided.

The body portion 21 and the locking portion 22 may be formed as separate members, and the locking portion 22 may be attached to the body portion 21 by welding or the like, but in the present embodiment, the body portion 21 and the locking portion 22 are integrally molded.

An engagement recess 23 is formed in a region adjacent to the proximal end of the locking portion 22 at the distal end 213 of the outer periphery of the body portion 21 of the housing 2. The engaging recess 23 is formed so as to surround the outer periphery of the main body portion 21 of the housing 2. When the waterproof sealing member 5 is attached to the distal end portion 213 of the outer periphery of the main body 21, the engagement concave portion 23 engages with the engagement convex portion 523 (see fig. 15) of the waterproof sealing member 5 to fix the waterproof sealing member 5. The engaging recess 23 has a depth corresponding to the amount of protrusion of the engaging projection 523 of the waterproof sealing member 5.

The pair of notches 24 are formed at the base end of the upper surface of the main body portion 21 of the housing 2 at positions corresponding to a pair of housing pressing portions 33 of the shield member 3 described later. The notches 24 are respectively formed by two concave portions formed at the base end of the upper surface of the main body portion 21 of the housing 2. In the assembled state of the electrical connector 1, the main body portion 21 of the housing 2 is pressed from the base end side by the pair of housing pressing portions 33 of the shield member 3 by the engagement of the pair of notches 24 and the pair of housing pressing portions 33 of the shield member 3, and the housing 2 is fixedly held inside the shield member 3.

The shield member 3 covers the housing 2 and the plurality of contacts 41 and the ground plate 42 of the inner structure 4 from the outside, thereby having a function of electromagnetically shielding (EMC) the plurality of contacts 41 and the ground plate 42 of the housing 2 and the inner structure 4. The shield member 3 has a function of fixing the electrical connector 1 to a circuit board provided in the housing 100 of the electronic device.

The shield member 3 is made of a metal material and has a cylindrical shape corresponding to the housing 2. The shield member 3 includes: a cylindrical body portion 31; two pairs of engaging projections 32 extending downward from the base end sides of both side surfaces of the body 31; a pair of housing pressing portions 33 which protrude downward from the upper surface of the body portion 31 and press the end surface of the housing 2 on the base end side of the body portion 21; and an internal structure pressing portion 34 that extends downward from the base end of the main body portion 31 and presses the end surface of the internal structure 4 on the base end side of the insulator 43 housed inside the main body portion 21 of the housing 2.

The main body portion 31 of the shield member 3 has a cylindrical shape having an inner diameter larger than the outer diameter of the cylindrical shape of the main body portion 21 of the housing 2 and smaller than the outer diameter of the locking portion 22 of the housing 2. As shown in fig. 7, the body 31 covers the body 21 of the housing 2 from the outside except for at least the front end 213 of the outer periphery of the body 21 of the housing 2. In the present embodiment, the body 31 covers the body 21 of the housing 2 from the outside except for the front end 213 of the outer periphery of the body 21 of the housing 2 and a part of the bottom surface and both side surfaces of the body 21 of the housing 2.

As shown in fig. 7, a recess along the circumferential direction for receiving and holding the waterproof sealing member 5 is formed by the distal end portion 213 of the outer periphery of the main body portion 21 of the housing 2 not covered with the main body portion 31 of the shield member 3, the locking portion 22 formed at the distal end of the main body portion 21 of the housing 2, and the end surface 311 of the shield member 3 on the distal end side of the main body portion 31.

The two pairs of engagement projections 32 are used to fix the electrical connector 1 to a circuit board of an electronic device. One of the two pairs of engaging projections 32 is formed to project downward from the base end side of both side surfaces of the body portion 31 of the shield member 3, and the other pair is formed to project downward from substantially the center portion of both side surfaces of the body portion 31 of the shield member 3. In a state where the electrical connector 1 is assembled, the two pairs of engaging projections 32 of the shield member 3 are inserted into engaging holes formed in the circuit board of the electronic device, and the electrical connector 1 is fixed to the circuit board of the electronic device.

The pair of housing pressing portions 33 are for pressing the body portion 21 of the housing 2 from the base end side in the assembled state of the electrical connector 1, and fixedly hold the housing 2 inside the body portion 31 of the shield member 3. The housing pressing portions 33 are each a U-shaped member integrally formed with the upper surface of the body portion 31 and protruding downward. Two portions corresponding to the sides of the U-shape are engaged with two recesses of the notch 24 of the housing 2, respectively. The pair of housing pressing portions 33 do not have a U shape protruding downward at a stage before the electrical connector 1 is assembled. When the electrical connector 1 is assembled, the housing 2 is positioned at a predetermined position inside the body portion 31 of the shield member 3, and then the housing pressing portions 33 are bent so as to protrude downward, thereby forming a U-shape and engaging with the notches 24 of the housing 2.

The internal structure pressing portion 34 is used to press the insulator 43 of the internal structure 4 housed inside the housing 2 from the base end side in a state where the electrical connector 1 is assembled, and fixedly hold the housing 2 and the internal structure 4. The inner structure pressing portion 34 is a flat plate-like member extending downward from the base end of the upper surface of the main body portion 31. In the assembled state of the electrical connector 1, the internal structure pressing portion 34 presses the insulator 43 of the internal structure 4 housed inside the housing 2 from the base end side. The inner structure pressing portion 34 extends rearward (in the negative direction of the Z axis in the drawing) from the base end of the upper surface of the main body portion 31 at a stage before the electrical connector 1 is assembled. When assembling the electrical connector 1, the housing 2 accommodating the internal structure 4 is positioned at a predetermined position inside the body portion 31 of the shield member 3, and then the internal structure pressing portion 34 is bent downward to press the insulator 43 of the internal structure 4 from the base end side.

The respective components of the shield member 3 (the main body portion 31, the two pairs of engagement protrusions 32, the housing pressing portion 33, and the internal structure pressing portion 34) may be configured as separate members and joined to each other by welding or the like, but in the present embodiment, the respective components of the shield member 3 are integrally molded.

In the electrical connector 1 of the present invention, the housing 2 is covered from the outside by the shield member 3 and electromagnetically shielded. As shown in fig. 7, a recess for receiving and holding the waterproof sealing member 5 is formed by the distal end portion 213 of the outer periphery of the main body portion 21 of the housing 2 which is not covered with the main body portion 31 of the shielding member 3, the distal end locking portion 22 formed on the main body portion 21 of the housing 2, and the end surface 311 of the shielding member 3 on the distal end side of the main body portion 31.

As shown in fig. 8, the internal structure 4 includes: a plurality of contacts 41 which provide electrical connection between the object side connector and the electrical connector 1 by being in contact with a plurality of contacts of the object side connector, respectively; a ground plate 42 arranged parallel to a plane on which the plurality of contacts 41 are arranged; an insulator 43 for holding the plurality of contacts 41 and the ground plate 42; and an inner waterproof sealing member 44 attached to the outer periphery of the insulator 43 so as to liquid-tightly seal the space inside the main body portion 21 of the housing 2.

As shown in fig. 9, the insulator 43 is made of an insulating material and has a function of holding the plurality of contacts 41 and the ground plate 42 while insulating the plurality of contacts 41 and the ground plate 42 from each other. The insulator 43 holds the plurality of contacts 41 and the ground plate 42 such that the plurality of contacts 41 can be brought into contact with the plurality of contacts of the mating connector and the ground plate 42 can be brought into contact with the ground terminal of the mating connector when the mating connector is inserted into the insertion port 211 of the housing 2 from the front end side in the assembled state of the electrical connector 1.

The insulator 43 includes: a base portion 431 which is press-fitted into the base end side opening 212 of the main body portion 21 of the housing 2 in order to fix the internal structure 4 to the main body portion 21 of the housing 2; and a tongue portion 432 extending from the base portion 431 toward the leading end side.

The base 431 is a member having a shape corresponding to the base end side opening 212 of the body portion 21 of the housing 2 in the XY plane, and the internal structure 4 is fixedly housed inside the body portion 21 of the housing 2 by pressing the base 431 into the base end side opening 212 of the body portion 21 of the housing 2. The fixing portions 412 (see fig. 10 and 11) of the plurality of contacts 41 and the ground plate 42 are embedded in the base 431 in a separated state, and the plurality of contacts 41 and the ground plate 42 are held by the insulator 43 in an insulated state.

As shown in fig. 8, the contact portion 411 of each of the plurality of contacts 41 protrudes from the front end side of the base 431 toward the front end side. On the other hand, as shown in fig. 6, the board connection portion 413 (see fig. 10 and 11) of each of the plurality of contacts 41 and the board connection portion 422 (see fig. 12) of the ground plate 42 protrude from the base end side of the base 431 toward the base end side.

Returning to fig. 9, a recess 433 is formed on the outer periphery of the base end side of the base 431. When the electrical connector 1 is assembled, the inner waterproof sealing member 44 is attached to the recess 433, and the gap between the inside of the main body portion 21 of the housing 2 and the outer periphery of the insulator 43 is liquid-tightly sealed by the inner waterproof sealing member 44, thereby providing a waterproof function for the inside of the main body portion 21 of the housing 2.

The tongue portion 432 of the insulator 43 is a flat plate-like member extending from the base portion 431 toward the distal end side, and is used for placing the plurality of contacts 41 and holding the ground plate 42 therein. A plurality of contact receiving portions 434 for mounting each of the plurality of contacts 41 shown in fig. 10 and 11 are formed on the upper surface and the lower surface of the tongue portion 432. An opening 435 for exposing the ground plate 42 is formed in the front end surface and the side surface of the tongue 432.

A plurality of contacts 41 are housed in a plurality of contact receiving portions 434 formed on the upper surface of the tongue-shaped portion 432, respectively, and a first group 41U of the plurality of contacts 41 shown in fig. 10 is configured. A plurality of contacts 41 are housed in a plurality of contact receiving portions 434 formed on the lower surface of the tongue-shaped portion 432, respectively, and a second group 41L of the plurality of contacts 41 shown in fig. 11 is constituted. In addition, the ground plate 42 is embedded in the tongue 432, and some portions of the ground plate 42 are exposed to the outside through the opening 435.

As shown in fig. 10, the first group 41U of the plurality of contacts 41 is constituted by a plurality of contacts 41 arranged in parallel to each other in the X-axis direction on the same plane (upper contact arrangement plane) and placed in a plurality of contact receiving portions 434 formed on the upper surfaces of the tongue-shaped portions 432, respectively. Similarly, the second group 41L of the plurality of contacts 41 is constituted by the plurality of contacts 41 arranged in parallel with each other in the X-axis direction on the same plane (lower contact arrangement plane) and placed in the plurality of contact receiving portions 434 formed on the lower surface of the tongue-shaped portion 432, respectively.

Each of the plurality of contacts 41 has a rod shape linearly extending in the Z-axis direction. Each of the plurality of contacts 41 includes a contact portion 411 on the tip end side that contacts the contact of the target-side connector, a fixing portion 412 embedded in the base portion 431 of the insulator 43, and a board connection portion 413 extending outward from the base portion 431 of the insulator 43 and connected to the circuit board of the electronic device.

When the mating connector is inserted from the distal end side through the insertion opening 211 of the main body 21 of the housing 2 in a state where the electrical connector 1 is assembled, the contact portion 411 of the contact 41 comes into contact with a corresponding contact of the mating connector. At this time, the mating connector and the electrical connector 1 are in a fitted state, and electrical connection between the mating connector and the electrical connector 1 is provided.

The fixing portions 412 of the contacts 41 extend in the same direction as the extending direction of the contact portions 411. The fixing portion 412 is fitted into the base portion 431 of the insulator 43, and the contact 41 is fixedly held by the insulator 43.

The substrate connection portion 413 of the contact 41 extends from the base end of the fixing portion 412 in the same direction as the extending direction of the fixing portion 412, and extends from the base portion 431 of the insulator 43 toward the outside. The substrate connection portion 413 is connected to a circuit substrate of the electronic apparatus.

The plurality of contacts 41 constituting the first group 41U include a plurality of signal contacts 41A for transmitting signals to and from the subject-side connector and a plurality of non-signal contacts 41B for purposes other than signal transmission. Similarly, the plurality of contacts 41 constituting the second group 41L include a plurality of signal contacts 41A for transmitting signals to and from the subject-side connector and a plurality of non-signal contacts 41B for purposes other than signal transmission (for example, power supply purposes). The number and arrangement of the signal contacts 41A and the non-signal contacts 41B of the first group 41U and the second group 41L are not particularly limited, and the electrical connector 1 is appropriately set according to the specification of the electrical connector.

As shown in fig. 12, the ground plate 42 is a flat plate-like member made of a metal material and embedded in the tongue-shaped portion 432 of the insulator 43. The ground plate 42 includes a flat plate-like body portion 421 and a pair of substrate connection portions 422 extending downward from a proximal end portion of the body portion 421 and exposed to the outside of the insulator 43.

The body 421 of the ground plate 42 is embedded in the tongue 432 of the insulator 43 so as to be parallel to the plane (upper contact arrangement plane and lower contact arrangement plane) in which the plurality of contacts 41 are arranged.

As shown in fig. 5, 6, and the like, portions of the main body 421 of the ground plate 42 are exposed to the outside through the openings 435 of the tongue portions 432 of the insulators 43. In the assembled state of the electrical connector 1, if the mating connector is inserted into the insertion port 211 of the body 21 of the housing 2, some portions of the body 421 of the ground plate 42 exposed to the outside through the openings 435 of the tongue-shaped portions 432 of the insulators 43 come into contact with the ground terminal of the mating connector.

The pair of substrate connection portions 422 of the ground plate 42 extend from both ends of the base end portion of the body 421, and extend outward from the base end side of the insulator 43. The pair of substrate connection portions 422 are connected to a circuit substrate of the electronic apparatus.

The inner waterproof sealing member 44 has a function of sealing the inside of the main body portion 21 of the housing 2 in a liquid-tight manner. The inner waterproof sealing member 44 is an annular elastic member (O-ring) made of an elastic material generally used for gaskets, such as a soft resin material, rubber, or silicon material. The inner waterproof seal member 44 is attached to a recess 433 formed on the outer periphery of the base 431 of the insulator 43. In the assembled state of the electrical connector 1, the inner waterproof sealing member 44 liquid-tightly seals the gap between the inside of the main body portion 21 of the housing 2 and the outer periphery of the insulator 43, providing a waterproof function of the inside of the main body portion 21 of the housing 2.

The waterproof sealing member 5 shown in fig. 13 to 15 has the following functions: when the electrical connector 1 is attached to the housing of the electronic device, a gap between the housing 100 of the electronic device and the electrical connector 1 is sealed in a liquid-tight manner, and the housing 100 of the electronic device and the electrical connector 1 are waterproofed. As shown in fig. 7, the waterproof sealing member 5 is provided to cover the distal end portion 213 of the outer periphery of the main body portion 21 of the housing 2 which is not covered with the shield member 3.

More specifically, the waterproof seal member 5 is held between the locking portion 22 of the housing 2 and the end surface 311 of the shielding member 3 on the distal end side of the body portion 31, and is positioned in a recess formed by the distal end portion 213 of the outer periphery of the body portion 21 of the housing 2 not covered with the body portion 31 of the shielding member 3, the locking portion 22 formed at the distal end of the body portion 21 of the housing 2, and the end surface 311 of the shielding member 3 on the distal end side of the body portion 31.

As shown in fig. 14 and 15, the waterproof sealing member 5 includes: a core 51 made of a hard material; and an elastic portion 52 formed to cover the core 51 so that at least the end surface 511 on the base end side of the core 51 is exposed.

The core 51 is made of a hard material such as stainless steel, a hard resin material, or a metal material. In the present embodiment, the core 51 has a cylindrical shape covering the distal end 213 of the outer periphery of the body 21 of the housing 2 not covered by the body 31 of the shield member 3. As shown in fig. 13 and 14, in the present embodiment, the core 51 has a flat cylindrical shape corresponding to the outer periphery of the body portion 21 of the housing 2, and the length of the core 51 in the width direction (Z-axis direction) of the electrical connector 1 is longer than the length of the core 51 in the height direction (Y-axis direction) of the electrical connector 1 in the cross-sectional shape of the core 51. The shape of the core 51 is not limited to the illustrated form, and is not particularly limited as long as it can cover the distal end 213 of the outer periphery of the body 21 of the housing 2.

As described above, in the waterproof sealing member 5 of the present invention, the core 51 made of a hard material is embedded in the elastic portion 52, and therefore the strength of the waterproof sealing member 5 is improved. Therefore, the waterproof sealing member 5 can be prevented from being wrinkled, twisted, or curled when the electrical connector 1 is inserted into the fitting hole 110 formed in the housing 100 of the electronic device.

The thickness of the core 51 is preferably 0.05 to 0.3mm, and more preferably 0.1 to 0.2 mm. If the thickness of the core 51 is less than the lower limit value, the strength of the core 51 may be insufficient, and it may be impossible to prevent the occurrence of wrinkles, twists, and curls of the waterproof sealing member 5 when the electrical connector 1 is inserted into the fitting hole 110 formed in the housing 100 of the electronic device. On the other hand, if the thickness of the core 51 exceeds the above upper limit value, the thickness of the waterproof sealing member 5 increases more than necessary, and there is a case where it is difficult to stably hold the waterproof sealing member 5. Further, the width of the core 51 in the Z-axis direction is preferably 0.1 to 5 mm.

As shown in fig. 15, an end surface 511 on the proximal end side of the core 51 is exposed from the elastic portion 52. Therefore, as shown in the vertical sectional view of fig. 16, in the assembled state of the electrical connector 1, the end surface 511 on the base end side of the core 51 is in contact with the end surface 311 on the tip end side of the body 31 of the shield member 3. In this way, the waterproof sealing member 5 is held between the locking portion 22 of the housing 2 and the end surface 311 of the main body portion 31 of the shield member 3 on the distal end side in a state where the end surface 511 of the core portion 51 on the proximal end side is in contact with the end surface 311 of the main body portion 31 of the shield member 3 on the distal end side. With such a configuration, the waterproof sealing member 5 can be stably held from the proximal end side to the end surface 311 on the distal end side of the body portion 31 of the shield member 3, and the waterproof sealing member 5 can be more reliably prevented from being wrinkled, twisted, or curled.

The elastic portion 52 has a function of sealing a space between the housing 100 of the electronic device and the electrical connector 1 in a liquid-tight manner. The elastic portion 52 is formed of an elastic material generally used for a gasket. Examples of such elastic materials include soft resin materials, rubbers, and silicon materials. The elastic portion 52 is formed to cover the core 51 so that at least the end surface 511 on the proximal end side of the core 51 is exposed.

As shown in fig. 15, in the present embodiment, the elastic portion 52 includes: a cylindrical body 521 covering the core 51 except for the end surface 511 on the proximal end side; an annular protrusion 522 protruding outward from the distal end of the body 521; and an annular engaging projection 523 projecting inward from the front end of the main body 521.

As shown in fig. 16, the thickness of the body 521 is larger than the thickness of the body 31 of the shield member 3 and the height of the locking portion 22 of the housing 2. The protrusion 522 is an annular portion formed to protrude outward from the distal end of the body 521, and when the electrical connector 1 is inserted into the fitting hole 110 formed in the case 100 of the electronic device, the protrusion 522 liquid-tightly seals a gap between the case 100 of the electronic device and the electrical connector 1, thereby providing a waterproof function between the case 100 of the electronic device and the electrical connector 1. The protrusion 522 has a tapered shape whose height decreases (monotonically decreases) from the base end side toward the tip end side. Therefore, when the electrical connector 1 is inserted into the fitting hole 110 formed in the housing 100 of the electronic device, the housing 100 of the electronic device comes into contact with the tapered surface of the protrusion 522, and the housing 100 of the electronic device slides on the tapered surface of the protrusion 522, so that resistance when the electrical connector 1 is inserted into the fitting hole 110 formed in the housing 100 of the electronic device is reduced.

In the tapered shape of the protrusion 522, the height of the proximal end portion having the largest height is preferably 0.2 to 1mm, and more preferably 0.3 to 0.7 mm. If the height of the base end portion of the projection 522 is lower than the lower limit value, the projection 522 may not be able to liquid-tightly seal the gap between the housing 100 of the electronic apparatus and the electrical connector 1. On the other hand, if the height of the base end portion of the protrusion 522 exceeds the upper limit value, resistance when the electrical connector 1 is inserted into the fitting hole 110 formed in the housing 100 of the electronic device becomes large, and the difficulty of the step of attaching the electrical connector 1 to the housing 100 of the electronic device may increase.

The engaging protrusion 523 is an annular protrusion formed to protrude inward from the front end of the main body 521, and engages with the engaging recess 23 of the housing 2 when the waterproof sealing member 5 is attached to the outer periphery of the main body 21 of the housing 2. With this configuration, the waterproof sealing member 5 can be more stably attached to the distal end portion 213 of the outer periphery of the main body portion 21 of the housing 2. The protruding amount of the engaging protrusion 523 is preferably 0.01 to 0.3mm, and more preferably 0.02 to 0.2 mm. If the amount of protrusion of the engaging projection 523 is less than the lower limit value, the engagement between the engaging recess 23 of the housing 2 and the engaging projection 523 becomes weak, and the waterproof sealing member 5 may not be stably attached to the outer periphery of the main body portion 21. On the other hand, if the protruding amount of the engaging protrusion 523 exceeds the above upper limit value, resistance when the body portion 21 of the housing 2 is inserted into the central opening portion of the waterproof sealing member 5 becomes large, and it may be difficult to attach the waterproof sealing member 5.

In the present embodiment, the body 521 covers the lower surface of the core 51. The inner diameter of the body 521 is larger than the outer diameter of the body 21 of the housing 2 and smaller than the outer diameter of the body 31 of the shield member 3. Therefore, the waterproof sealing member 5 can be easily attached to the distal end portion 213 of the outer periphery of the main body portion 21 of the housing 2 in the following procedure. First, the waterproof sealing member 5 is attached from the proximal end side, and the waterproof sealing member 5 is advanced until the engagement protrusion 523 of the waterproof sealing member 5 engages with the engagement recess 23 formed in the outer periphery of the main body portion 21 of the housing 2. Thereafter, the shield member 3 is attached to the body portion 21 of the housing 2 from the proximal end side, and the shield member 3 is advanced until the proximal end side end surface 511 of the core portion 51 of the waterproof sealing member 5 and the distal end side end surface 311 of the body portion 31 of the shield member 3 come into contact with each other. Thereby, the waterproof sealing member 5 can be provided to cover the distal end portion 213 of the outer periphery of the main body portion 21 of the housing 2 not covered by the shield member 3. As described above, in the present invention, the waterproof sealing member 5 can be easily attached so as to cover the outer peripheral front end portion 213 of the main body portion 21 of the housing 2 without using an additional member.

Fig. 16 shows a longitudinal section of the electrical connector 1. As is apparent from fig. 16, the waterproof sealing member 5 is held between the locking portion 22 of the housing 2 and the end surface 311 of the shielding member 3 on the distal end side of the body portion 31, and the end surface 511 of the waterproof sealing member 5 on the proximal end side of the core portion 51 is in contact with the end surface 311 of the shielding member 3 on the distal end side of the body portion 31.

Fig. 17 is a longitudinal sectional view of the electrical connector 1 and the housing 100 of the electronic device in a state where the electrical connector 1 of the present invention having the above-described configuration is mounted on the housing 100 of the electronic device. As shown in fig. 17, a gap between the case 100 of the electronic apparatus and the electrical connector 1 is liquid-tightly sealed by the waterproof sealing member 5. In the interior of the main body portion 21 of the housing 2 of the electrical connector 1, a gap between the inner surface of the main body portion 21 of the housing 2 and the insulator 43 of the internal structure 4 is liquid-tightly sealed by an inner waterproof sealing member 44. With such a configuration, a waterproof function between the housing 100 of the electronic device and the electrical connector 1 and a waterproof function inside the electrical connector 1 can be provided.

As described above, in the electrical connector 1 according to the present invention, since the core 51 made of a hard material is embedded in the elastic portion 52 of the waterproof sealing member 5, the strength of the waterproof sealing member 5 is improved, and the waterproof sealing member 5 is less likely to be wrinkled, twisted, or curled. Therefore, the waterproof sealing member 5 can be prevented from being wrinkled, twisted, or curled when the electrical connector 1 of the present invention is inserted into the fitting hole 110 formed in the housing 100 of the electronic device, and the waterproof function between the housing 100 of the electronic device and the electrical connector 1 can be reliably provided.

In the electrical connector 1 of the present invention, the waterproof sealing member 5 is held between the locking portion 22 of the housing 2 and the end surface 311 of the shielding member 3 on the distal end side of the body portion 31, and the end surface 511 of the waterproof sealing member 5 on the proximal end side of the core portion 51 is in contact with the end surface 311 of the shielding member 3 on the distal end side of the body portion 31. With this configuration, the waterproof sealing member 5 can be held more stably on the outer periphery of the main body portion 21 of the housing 2. As a result, the waterproof sealing member 5 can be more reliably prevented from being wrinkled, twisted, or curled, and the waterproof function between the housing 100 of the electronic device and the electrical connector 1 can be more reliably provided.

< second embodiment >

Next, an electrical connector according to a second embodiment of the present invention will be described in detail with reference to fig. 18 and 19. Fig. 18 is a side view showing a waterproof sealing member of an electrical connector according to a second embodiment of the present invention. Fig. 19 is a partially enlarged view of a cross-sectional view of the waterproof sealing member shown in fig. 18.

Hereinafter, the electrical connector 1 of the second embodiment will be described mainly with differences from the electrical connector 1 of the first embodiment, and the description of the same matters will be omitted. The electrical connector 1 of the present embodiment has the same configuration as the electrical connector 1, except that the configuration of the waterproof sealing member 5 is changed.

As shown in fig. 18 and 19, in the present embodiment, the elastic portion 52 of the waterproof sealing member 5 is formed so as to cover the core 51 so that the end surface 511 on the proximal end side of the core 51 and the proximal end portion 512 on the outer periphery of the core 51 are exposed.

In the present embodiment, in the assembled state of the electrical connector 1, the proximal end portion 512 of the outer periphery of the core portion 51 of the waterproof sealing member 5 is not covered with the elastic portion 52, but is exposed to the outside. Therefore, the exposed proximal end portion 512 of the outer periphery of the core 51 and the distal end portion of the main body portion 31 of the shield member 3 can be joined by welding or the like.

By joining the exposed proximal end portion 512 of the outer periphery of the core portion 51 and the distal end portion of the body portion 31 of the shield member 3 by welding or the like, the waterproof seal member 5 can be held more stably between the locking portion 22 of the housing 2 and the end surface 311 of the body portion 31 of the shield member 3.

While the electrical connector 1 of the present invention has been described above based on the illustrated embodiment, an electronic device including the electrical connector 1 of the present invention as described above is also within the scope of the present invention. As shown in fig. 17, the electronic device of the present invention includes a housing 100, a circuit board (not shown) provided in the housing 100, and the electrical connector 1 mounted on the circuit board.

The electrical connector and the electronic device according to the present invention have been described above based on the illustrated embodiments, but the present invention is not limited thereto. The respective configurations of the present invention may be replaced with any configurations that can exhibit the same function, or any configurations may be added to the respective configurations of the present invention.

For example, in each embodiment of the electrical connector 1, the locking portion 22 of the housing 2 has an annular shape formed around the front end of the outer periphery of the body portion 21, but the shape of the locking portion 22 is not limited to this as long as the locking portion 22 can provide a function of locking the waterproof seal member 5 from the front end side. For example, the locking portion 22 may have a discontinuous annular shape with a plurality of notches formed therein, and the locking portion 22 may be formed of one or more protruding portions formed to protrude outward from the outer periphery of the body portion 21.

In each embodiment of the electrical connector 1, the core 51 of the waterproof sealing member 5 has an annular shape covering the outer periphery of the body 21 of the housing 2, but the shape of the core 51 is not limited to this as long as the core 51 can function as a core of the waterproof sealing member 5 for preventing wrinkles, twists, and curls of the waterproof sealing member 5. For example, the core 51 may have a discontinuous annular shape with a part cut away, or may be formed of a plurality of hard plates embedded in the elastic portion 52 so as to be separated from each other to form a discontinuous annular shape surrounding the outer periphery of the main body portion 21 of the outer shell 2.

In each embodiment of the electrical connector 1, the plurality of contacts 41 of the inner structure 4 form the first group 41U and the second group 41L that face each other with the tongue 432 of the insulator 43 and the ground plate 42 embedded in the tongue 432 interposed therebetween, but the present invention is not limited to this. For example, a configuration in which the plurality of contacts 41 form only one of the first group 41U and the second group 41L, and a configuration in which the plurality of contacts 41 form one or more additional groups in addition to the first group 41U and the second group 41L are also within the scope of the present invention.

A person skilled in the art can change the configuration of the authentication apparatus of the present invention described without intentionally departing from the principle, concept, and scope of the present invention, and an authentication apparatus having a changed configuration is also within the scope of the present invention. For example, any combination of the electrical connectors according to the first and second embodiments is also within the scope of the present invention.

The number and types of components of the electrical connector shown in fig. 3 to 19 are merely illustrative, and the present invention is not limited thereto. It is also within the scope of the present invention to add or combine any of the components or to delete any of the components without departing from the principle and intent of the present invention.
