Description

Electric connector, manufacturing method of electric connector and mounting method of electric connector

Technical Field

The present invention relates to an electrical connector having a housing and a receptacle mounted on a mounting surface of a substrate, a method of manufacturing the electrical connector, and a method of mounting the electrical connector.

Background

Conventionally, as an electrical connector used for in-vehicle use and the like, an electrical connector having a structure in which a receptacle is held inside a housing such as an outer housing (outer housing) is known.

Patent document 1 discloses an electrical connector having: a pair of arm portions for holding the socket by elastic force; and a locking portion having a locking surface and provided at a tip end of the arm portion, wherein the locking surface is parallel to a plane orthogonal to a direction in which the socket is fitted. The electrical connector of patent document 1 has a pressing surface at a corner formed by the locking surface and the arm portion, the pressing surface pressing the socket in the fitting direction when the arm portion clamps the socket. This makes it possible to hold the socket in the outer case without rattling.

In addition, the electrical connector of patent document 1 needs to maintain flatness (hereinafter, referred to as "coplanarity") of the terminal portion of the socket with respect to the mounting surface of the substrate. Furthermore, the electrical connector of patent document 1 needs to maintain coplanarity in consideration of the positional accuracy of the fixing position of the socket and the housing and the connecting position of the housing and the substrate. For example, when the terminal pitch of the socket is 0.8mm, coplanarity of 0.15mm or less is required.

However, in patent document 1, the narrower the pitch of the terminal portions of the socket is, the more severe the required coplanarity is, and therefore there is a problem that the required coplanarity cannot be handled by taking into consideration the position accuracy of the fixing position of the socket and the housing and the connecting position of the housing and the substrate. For example, patent document 1 has the following problems: when the terminal pitch of the socket is 0.5mm or less, the coplanarity required for the socket is 0.08mm or less, and thus the required coplanarity cannot be satisfied.

(first embodiment)

Structure of electric connector

The structure of the electrical connector 1 according to the first embodiment of the present invention will be described in detail with reference to fig. 1 to 14.

The electrical connector 1 of the present embodiment has a housing (case) 2, a hold down (hold down) 3, and a receptacle 4.

The housing 2 is made of an insulating material such as resin, and includes a pressing portion 18, a front wall portion 19, a protruding wall portion 20, a housing portion 21, an engaging portion 22, an abutting portion 23, a fitting portion 24, an insertion portion 25, a protruding portion 26, a flat portion 27, a rear wall portion 28, an inner top wall portion 29, and an opening portion 30. The front wall 19, the protruding wall 20, and the engaging portion 22 constitute a holding portion that holds the receptacle 4 in the housing portion 21 so as to restrict the receptacle 4 accommodated in the housing portion 21 from moving forward, backward, leftward, rightward, and downward.

As shown in fig. 5, the pressing portion 18 protrudes downward from the inner ceiling wall 29 between a protruding portion 412, which will be described later, of the receptacle 4 and the terminal portion 422. The pressing portion 18 faces the receptacle 4 with a gap between the pressing portion 18 and the receptacle 4 held in the housing 21, and the pressing portion 18 abuts against the receptacle 4 when the housing 2 and the receptacle 4 are mounted on the mounting surface 100a of the board 100.

The front wall 19 is provided in front of the housing 21, and restricts forward movement of the receptacle 4 held in the housing 21.

The protruding wall 20 is provided behind the engaging portion 22, and restricts rearward movement of the receptacle 4 accommodated in the accommodating portion 21.

The housing 21 is provided on a lower surface, which is a bottom surface of the case 2 facing the mounting surface 100a of the substrate 100, and communicates with the outside at its rear end. The housing 21 houses the socket 4 in a state where the socket 4 is exposed to the outside.

A pair of engaging portions 22 as elastic portions are provided on the inner walls of the left and right sides of the housing portion 21. The engaging portion 22 includes an inwardly protruding engaging claw 221 at a lower end. The engagement portion 22 is elastically deformable in the left-right direction between the insertion portion 25 and the accommodating portion 21. The engaging claw 221 of the engaging portion 22 engages with an engaged portion 432 of a cover 43 described later of the receptacle 4 to restrict downward movement of the receptacle 4.

The abutment portion 23 is provided at the front end of the accommodating portion 21 at the lower ends of the left and right side walls. When the housing 2 has been mounted on the mounting surface 100a of the board 100, the abutting portion 23 abuts on the mounting surface 100a.

The fitting portion 24 is formed in a tubular shape provided in the protruding portion 26 and having a distal end thereof opened to the outside, and is capable of fitting with a counterpart connector not shown.

The insertion portion 25 is a through hole penetrating in the vertical direction around the housing portion 21, and is configured to allow the pressing tool 3 to be inserted therethrough.

When the housing 2 has been mounted on the mounting surface 100a of the board 100, the protruding portion 26 protrudes outward and forward from the board 100 (see fig. 7).

The flat portion 27 is provided on the rear upper surface of the housing 2 and is flat in the front-rear direction and the left-right direction.

The rear wall 28 is provided at the rear end of the housing 2, and the center in the lateral direction thereof is recessed forward.

The inner top wall portion 29 is provided above the accommodating portion 21.

The opening 30 is provided in the front wall 19, and communicates the accommodating portion 21 with the fitting portion 24 (see fig. 5).

The pressing member 3 is formed by bending a metal plate after punching the metal plate by press working, and is an attaching member attached to the housing 2 so as to fix the housing 2 to the substrate 100. The pressing tool 3 is inserted into the insertion portion 25 of the housing 2 and is mounted to the housing 2. The pressing tool 3 includes a top surface portion 31, a rear surface portion 32, an inner side surface portion 33, a leg portion 34, a front surface portion 35, and an outer side surface portion 36.

The top surface portion 31 covers the flat portion 27.

The rear surface portion 32 is formed to be bent downward from the rear end of the top surface portion 31 and to cover the rear wall portion 28.

The inner side surface portion 33 is formed to be bent rearward from the left and right ends of the front surface portion 35, is provided on the left and right sides of the top surface portion 31, and is inserted into the insertion portion 25. The inner side surface portions 33 each include a restricting portion 331 near, i.e., above, the front leg portion 34 of the pair of leg portions 34.

The restricting portion 331 is provided opposite the locking claw 221 on the left and right outer sides of the locking claw 221. The restricting portion 33 restricts the elastic deformation of the engaging portion 22 to the left and right outside, which causes the socket 4 to drop downward from the accommodating portion 21, and allows the engaging portion 22 to be elastically deformed to the left and right outside within a range where the socket 4 does not drop downward from the accommodating portion 21. Here, the left and right outer sides are directions in which the receptacle 4 is separated downward from the housing 21.

The leg portions 34 as welding portions extend downward from lower ends of the left and right inner side surface portions 33. Each of the inner side surface portions 33 is provided with a pair of legs 34 at intervals in the front-rear direction. The leg 34 protrudes downward from the insertion portion 25 and is located above the bottom surface of the housing 2.

The front surface portion 35 is formed to be bent downward from the front end of the top surface portion 31 and inserted into the insertion portion 25.

The outer side surface 36 is formed to be bent forward from the left and right ends of the rear surface 32, and covers the rear end side of the left and right side surface of the housing 2.

The receptacle 4 includes a shield shell 41, contacts 42, a cover 43, and a housing (housing) 44.

The shield case 41 is formed by punching a metal plate by press working and bending the metal plate, and includes a fitting portion 411 that opens forward to fit into a mating connector, not shown. The shield shell 41 includes a protruding portion 412, and the protruding portion 412 protrudes downward from the bottom surface and is welded so as to abut against the mounting surface 100a when the receptacle 4 has been mounted on the mounting surface 100a of the board 100.

As shown in fig. 3, the protruding portion 412 is provided between the terminal portion 422 and the contact portion 23, and a pair of left and right protruding portions 412 are provided across a joint formed when the metal plates constituting the shield case 41 are bent. The protruding portion 412 is welded to the mounting surface 100a, but is not limited thereto, and may be in contact with only the mounting surface 100a without being welded.

The contact 42 is formed of a conductive material and is mounted on the housing 44. The contact 42 includes: a connection portion 421 connected to a conductive portion of a counterpart connector, not shown; and a terminal portion 422 welded to the mounting surface 100a of the board 100. In a state in which the engagement claw 221 of the engagement portion 22 engages with the engaged portion 432 of the cover 43 and the receptacle 4 is held in the accommodating portion 21, the terminal portion 422 is positioned below the abutment portion 23 (see fig. 14).

The cover 43 is formed by bending a metal plate after punching the metal plate by press working, and is mounted to the shield case 41 in an insulated state from the contacts 42. The cover 43 includes: a leg 431 connected to a conductive portion, not shown, of the mounting surface 100a of the board 100; and an engaged portion 432 engaged with the locking claw portion 221 of the locking portion 22. The section of the engaged portion 432 has a width of the metal plate constituting the cover 43 at the plate thickness level.

The base 44 is made of an insulating material such as resin, and is covered with the shield case 41. The housing 44 holds the contacts 42 in an insulated state from the shield shell 41 and the cover 43.

The socket 4 having the above-described structure is opposed to the pressing portion 18 of the housing 2 with a space therebetween in a state of being held in the accommodating portion 21, and is thereby relatively movable upward with respect to the housing 2.

Method for manufacturing electric connector

Hereinafter, a method of manufacturing the electrical connector 1 according to the first embodiment of the present invention will be described in detail with reference to fig. 1 to 13.

First, the housing 2 is formed in advance using a resin material by injection molding or the like, and the metal plate is subjected to press working to form the press 3. In addition, the socket 4 manufactured by the existing method is ready. At this time, the socket 4 having the terminal portions 422 of the number or pitch corresponding to the purpose may be selected.

Next, an insertion step of inserting the receptacle 4 into the accommodating portion 21 of the housing 2 from the front and from the bottom of the protruding wall portion 20 is performed. At this time, the socket 4 is inserted into the accommodating portion 21 while elastically deforming the engaging portion 22 of the housing 2 to the left and right outer sides by the cover 43 of the socket 4.

Next, the following holding process is performed: by inserting the receptacle 4 into the accommodating portion 21 from below until the cover 43 of the receptacle 4 passes the engaged portion 432, the engaging claw 221 of the engaging portion 22 is engaged with the engaged portion 432 of the cover 43 by the elastic restoring force of the engaging portion 22 of the housing 2, and the receptacle 4 is held in the accommodating portion 21. At this time, the receptacle 4 is held in the housing 21 in a state in which downward movement is regulated by the locking claw 221 of the locking portion 22, rearward movement is regulated by the protruding wall portion 20, and forward movement is regulated by the front wall portion 19.

Then, the leg portion 34 of the pressing tool 3 is inserted into the insertion portion 25 of the housing 2 from above, and then inserted into the inner side surface portion 33 and the front surface portion 35.

Then, the inner side surface portion 33 and the front surface portion 35 of the pressing member 3 are further inserted into the insertion portion 25, whereby the top surface portion 31 abuts against the flat portion 27 to cover the flat portion 27, the rear surface portion 32 covers the rear wall portion 28, and the outer side surface portion 36 covers the rear end sides of the left side surface portion and the right side surface portion of the housing 2. Thereby, the electrical connector 1 is completed.

In the completed state of the electrical connector 1, the engaging portion 22 is restricted from being elastically deformed outward and leftward by the restricting portion 331 of the inner side portion 33, whereby the receptacle 4 can be prevented from falling downward from the housing portion 21 before the electrical connector 1 is mounted on the mounting surface 100a of the substrate 100.

In particular, since the engagement width of the engaged portion 432 with the engagement claw portion 221 is only the plate thickness of the metal plate constituting the cover 43, the engagement between the engagement claw portion 221 and the engaged portion 432 is in an extremely shallow engaged state, and therefore, when an external force such as an impact is applied to the electrical connector 1 before the electrical connector 1 is mounted on the substrate 100 without restricting the elastic deformation of the engagement portion 22 to the left and right by the restricting portion 331, the engagement between the engagement claw portion 221 and the engaged portion 432 is easily released, and the receptacle 4 is disengaged from the housing 2.

In contrast, in the present embodiment, the engaging portion 22 is restricted from being elastically deformed outward and leftward by the restricting portion 331 of the pressing member 3, and therefore, even in a case where the engaging claw portion 221 and the engaged portion 432 are in an extremely shallow engaged state, the engaging portion 22 is prevented from being elastically deformed outward and leftward when an external force such as an impact is applied to the electrical connector 1, and the receptacle 4 is prevented from falling off the housing 2.

Mounting method of electric connector

Hereinafter, a method of mounting the electrical connector 1 according to the first embodiment of the present invention will be described in detail with reference to fig. 1 to 15.

The top surface 31 of the electrical connector 1 manufactured by the above-described manufacturing method is sucked by a suction nozzle of a mounting machine, not shown, and the electrical connector 1 is transferred to the mounting surface 100a of the board 100. At this time, the engagement claw 221 of the engagement portion 22 engages with the engaged portion 432 of the cover 43, whereby the terminal portion 422 of the receptacle 4 is positioned below the contact portion 23 of the housing 2 by a distance H1 as shown in fig. 14. The socket 4 is opposed to the pressing portion 18 of the housing 2 protruding downward from the inner ceiling wall 29 with a gap R1 therebetween.

Then, the leg portion 34 of the pressing member 3 of the electrical connector 1 is inserted into the through hole 100b of the substrate 100 from above.

By inserting the leg 34 into the through hole 100b, first, the terminal portion 422 of the contact 42 of the receptacle 4 and the protruding portion 412 of the shield shell 41 are brought into contact with the mounting surface 100a, and then the contact portion 23 of the housing 2 is brought into contact with the mounting surface 100a.

Before the terminal portion 422 and the protruding portion 412 are brought into contact with the mounting surface 100a, as shown in fig. 14, a vertical interval H2 between the lower end portion of the contact portion 23 and the upper end portion of the locking claw portion 221 is smaller than a vertical interval H3 (H2 < H3) between the lower end portion of the engaged portion 432 of the socket 4 and the welding surface of the terminal portion 422, and the welding surface of the terminal portion 422 and the lower end portion of the protruding portion 412 are located below the lower end portion of the contact portion 23 by H1. In this state, the terminal portion 422 and the protruding portion 412 are in contact with the mounting surface 100a, and thus the engaged portion 432 moves upward relative to the locking claw portion 221 so as to be away from the locking claw portion 221, and the receptacle 4 moves upward relative to the housing 2 by an amount of a gap (h3—h2=h1) in the accommodating portion 21. Thereby, the socket 4 is free from the housing 2.

Further, by moving the socket 4 upward relative to the housing 2, the soldered surface of the terminal portion 422 and the lower end portion of the contact portion 23 are located at substantially the same position (h1≡0) in the up-down direction as shown in fig. 15. Since the interval R1 is substantially the same as the distance H1 (r1≡h1), the socket 4 is relatively moved upward with respect to the housing 2, and is brought into contact with the pressing portion 18 (r1=0), and is pressed against the mounting surface 100a from above by the pressing portion 18.

The present invention is configured such that the soldering surface of the terminal portion 422 of the receptacle 4 is located below the lower end portion of the contact portion 23 of the housing 2 before the electrical connector 1 is mounted on the substrate 100, but the present invention is not limited thereto, and the soldering surface of the terminal portion 422 and the lower end portion of the contact portion 23 may be located at the same height (h1=0 and h2=h3) in the vertical direction. In this case, even after the terminal portion 422 and the protruding portion 412 are brought into contact with the substrate 100, the locking claw portion 221 is not completely separated from the engaged portion 432, and the receptacle 4 is similarly free from the influence of the housing 2 as long as the self weight of the receptacle 4 is not applied to the locking claw portion 221 via the engaged portion 432.

Further, the restricting portion 331 of the pressing member 3 allows the engaging portion 22 to be elastically deformed to the left and right outside within a range that the socket 4 does not fall downward from the accommodating portion 21, so that the terminal portion 422 can be reliably brought into contact with the soldering position of the mounting surface 100a while adjusting the position of the terminal portion 422 in the left and right directions with respect to the soldering position of the mounting surface 100a.

Next, the terminal portion 422 and the protruding portion 412 of the socket 4 are soldered to the conductive portion, not shown, of the mounting surface 100a of the substrate 100, and the leg portion 34 of the pressing member 3 is soldered to the conductive portion, not shown, of the through hole 100b of the substrate 100, whereby the mounting of the electrical connector and the substrate 100 is completed. At this time, since the socket 4 is in the state in which the engagement between the engaged portion 432 and the engagement claw portion 221 has been released as described above, the coplanarity of the terminal portion 422 with respect to the mounting surface 100a of the substrate 100 can be maintained in a good state without being affected by the housing 2.

Further, since the socket 4 is pressed against the mounting surface 100a from above by the pressing portion 18, the terminal portion 422 and the protruding portion 412 can be prevented from tilting from the mounting surface 100 a. At this time, the socket 4 is pressed against the mounting surface 100a from above by the pressing portion 18 between the terminal portion 422 that abuts against the mounting surface 100a and the protruding portion 412 that abuts against the mounting surface 100a, and therefore can be mounted in a parallel state without being inclined in the front-rear direction with respect to the mounting surface 100 a.

As shown in fig. 7, the electrical connector 1 mounted on the substrate 100 by the above-described mounting method has the protruding portion 26 of the housing 2 protruding outward from the substrate 100. In this state, by providing the pressing member 3, the portion of the electrical connector 1 that overlaps the substrate 100 when viewed from above (in the state shown in fig. 7) has a center of gravity position. Thus, the electrical connector 1 can be mounted on the substrate 100 in a stable state.

Further, by providing the restricting portion 331 above the leg portion 34 soldered to the conductive portion of the through hole 100b, even when the restricting portion 331 is pressed to the left and right outer sides by the engaging portion 22 in the state where the electrical connector 1 is mounted on the mounting surface 100a of the substrate 100, the engaging portion 22 can be reliably restricted from being elastically deformed to the left and right outer sides by the restricting portion 331.

As described above, according to the present embodiment, in the electrical connector 1 having the housing 2 mounted on the mounting surface 100a of the substrate 100 and the receptacle 4, the housing 2 includes: a housing portion 21 provided on a bottom surface facing the mounting surface 100a and configured to house the receptacle 4 in a state in which the receptacle 4 is exposed to the outside; a front wall 19, a protruding wall 20, and an engaging portion 22 for holding the receptacle 4 in the accommodating portion 21; and an abutting portion 23 abutting against the mounting surface 100a, wherein the socket 4 is provided with a terminal portion 422 welded to the mounting surface 100a, and the terminal portion 422 is positioned at the same height as the abutting portion 23 or below the abutting portion 23 in a state in which the socket 4 is held by the front wall portion 19, the protruding wall portion 20, and the engaging portion 22 in the housing portion 21, and the socket 4 is movable upward, whereby the coplanarity of the terminal portions 422 of the socket 4 can be maintained in a good state even if the pitch of the terminal portions 422 of the socket 4 is narrow.

Further, according to the present embodiment, there is provided: a housing 2 mounted on the mounting surface 100a of the substrate 100; the socket 4 is mounted on the mounting surface 100a in a state of being accommodated in the housing 2; and a pressing member 3 attached to the housing 2, the housing 2 including: a housing portion 21 that houses the receptacle 4; and a front wall 19, a protruding wall 20, and an engaging portion 22 for holding the receptacle 4 in the housing 21, the holding portion including: the engaging portion 22 holds the socket 4 in the housing portion 21 by an elastic force, and is elastically deformable, and the pressing member 3 includes a restricting portion 331 that restricts the engaging portion 22 from being elastically deformed in a direction in which the socket 4 is separated from the housing portion 21, thereby preventing the socket 4 from being separated from the housing 2.

Further, according to the present embodiment, the pressing tool 3 for fixing the housing 2 to the substrate 100 restricts the elastic deformation of the engaging portion 22 in the direction in which the receptacle 4 is separated from the accommodating portion 21, so that the pressing tool 3 can serve as both the member for fixing the housing 2 to the substrate 100 and the member for restricting the elastic deformation of the engaging portion 22 in the direction in which the receptacle 4 is separated from the accommodating portion 21, thereby suppressing an increase in the number of components.

(second embodiment)

Structure of electric connector

The structure of the electrical connector 11 according to the second embodiment of the present invention will be described in detail below with reference to fig. 16 to 19.

In fig. 16 to 19, the same reference numerals are given to the same components as those in fig. 1 to 15, and the description thereof is omitted.

The electrical connector 11 of the present embodiment has a socket 4, a housing 5, and a pressing member 6.

The housing 5 is made of an insulating material such as resin, and includes a front wall 19, a protruding wall 20, a housing 21, an engaging portion 22, an abutting portion 23, a fitting portion 24, an insertion portion 25, a protruding portion 26, an inner top wall 29, an opening 30, a spring portion 51, a movable portion 52, and a rear wall 53. The spring portion 51 and the movable portion 52 constitute a pressing spring portion.

The receiving portion 21 is concavely provided on the bottom surface, i.e., the lower surface, of the housing 5, and the rear end thereof communicates with the outside.

The insertion portion 25 is a through hole penetrating in the vertical direction around the housing portion 21, and is configured to allow the pressing tool 6 to be inserted therethrough.

When the housing 5 has been mounted on the mounting surface 100a of the board 100, the protruding portion 26 protrudes outward and forward from the board 100.

The inner top wall 29 is provided above the housing 21 and faces the receptacle 4 held in the housing 21 with a space therebetween.

The spring portion 51 connects the movable portion 52 and the rear wall portion 53. The spring portion 51 elastically deforms when the movable portion 52 is pressed downward to allow the movable portion 52 to move downward, and moves the movable portion 52 upward by an elastic restoring force when the downward pressing force against the movable portion 52 is released.

The movable portion 52 is provided above the housing portion 21 and faces the receptacle 4 held in the housing portion 21 with a space therebetween. The movable portion 52 moves downward when pressed downward to press the socket 4 held in the housing portion 21 downward, and moves upward when the downward pressing force is released to release the downward pressing of the socket 4 held in the housing portion 21.

The rear wall portion 53 is provided on the right and left sides of the movable portion 52 at the rear end of the housing 5, and is recessed forward toward the movable portion 52.

The pressing piece 6 is formed by bending a metal plate after punching the metal plate by press working, and is an attaching member attached to the housing 5 so as to fix the housing 5 to the substrate 100. The pressing tool 6 is inserted into the insertion portion 25 of the housing 5 and is mounted to the housing 5. The presser 6 includes a rear surface portion 32, an inner side surface portion 33, a leg portion 34, a front surface portion 35, a top surface portion 61, and a window portion 62.

The rear surface portion 32 is formed to be bent downward from the rear end of the top surface portion 61, and covers the rear end of the movable portion 52 and the rear wall portion 53.

The inner side surface portion 33 is formed to be bent rearward from the left and right ends of the front surface portion 35, is provided on the left and right sides of the top surface portion 61, and is inserted into the insertion portion 25.

The leg 34 protrudes downward from the insertion portion 25 and is located above the bottom surface of the housing 5.

The front surface portion 35 is formed to be bent downward from the front end of the top surface portion 61 and inserted into the insertion portion 25.

The top surface portion 61 covers the upper ends of the spring portion 51 and the movable portion 52.

The window 62 is a through hole penetrating in the plate thickness direction provided in the substantially center of the top surface 61, and exposes a part of the movable portion 52 to the outside.

In the electrical connector 11 having the above-described configuration, the engaging portion 22 is restrained from being elastically deformed laterally outward by the restraining portion 331 of the inner side portion 33, so that the receptacle 4 can be prevented from falling downward from the housing portion 21 before the electrical connector 11 is mounted on the substrate 100.

The method of manufacturing the electrical connector 11 according to the present embodiment is the same as the method of manufacturing the electrical connector 1, and therefore, the description thereof is omitted.

Mounting method of electric connector

Hereinafter, a method of mounting the electrical connector 11 according to the second embodiment of the present invention will be described in detail with reference to fig. 16 to 19.

The suction nozzle 200 of the mounter sucks the upper surface of the movable portion 52 of the housing 5 exposed to the outside from the window 62 of the pressing member 6 of the electrical connector 11, and transfers the electrical connector 11 to the mounting surface 100a of the board 100. At this time, the engagement claw 221 of the engagement portion 22 engages with the engaged portion 432 of the cover 43, whereby the terminal portion 422 of the receptacle 4 is positioned below the contact portion 23 of the housing 5. The socket 4 is opposed to the inner ceiling wall 29 and the movable portion 52 of the housing 5 with a space therebetween.

Then, the leg portion 34 of the pressing member 6 of the electrical connector 11 is inserted into the through hole 100b of the substrate 100 from above.

By inserting the leg 34 into the through hole 100b, the terminal portion 422 of the contact 42 of the receptacle 4 and the protruding portion 412 of the shield shell 41 are first brought into contact with the mounting surface 100a, and then the contact portion 23 of the housing 5 is brought into contact with the mounting surface 100a.

Before the terminal portion 422 and the protruding portion 412 are brought into contact with the mounting surface 100a, the interval in the up-down direction between the lower end portion of the contact portion 23 and the upper end portion of the locking claw 221 is smaller than the interval in the up-down direction between the lower end portion of the engaged portion 432 of the receptacle 4 and the welding surface of the terminal portion 422, and the welding surface of the terminal portion 422 and the lower end portion of the protruding portion 412 are located below the lower end portion of the contact portion 23. In this state, the terminal portion 422 and the protruding portion 412 are brought into contact with the mounting surface 100a, so that the engaged portion 432 moves upward relative to the locking claw portion 221 and moves away from the locking claw portion 221, and the receptacle 4 moves upward relative to the housing 5 in the accommodating portion 21. Thereby, the socket 4 is free from the housing 5.

Further, by relatively moving the socket 4 upward with respect to the housing 5, the terminal portion 422 of the socket 4 is located at substantially the same position as the contact portion 23 of the housing 5 in the up-down direction. Further, the socket 4 is moved upward relative to the housing 5, and thus, is opposed to the inner ceiling wall 29 and the movable portion 52 so as to be closer to the inner ceiling wall 29 and the movable portion 52 of the housing 5 than before being attached to the attachment surface 100 a.

The present invention is configured such that the soldering surface of the terminal portion 422 of the receptacle 4 is located below the lower end portion of the contact portion 23 of the housing 5 before the electrical connector 11 is mounted on the substrate 100, but the present invention is not limited thereto, and the soldering surface of the terminal portion 422 and the lower end portion of the contact portion 23 may be located at the same height in the vertical direction. In this case, even after the terminal portion 422 is brought into contact with the substrate 100, the locking claw portion 221 is not completely separated from the engaged portion 432, and the receptacle 4 is similarly free from the influence of the housing 5 as long as the self weight of the receptacle 4 is not applied to the locking claw portion 221 via the engaged portion 432.

Further, the restricting portion 331 of the pressing member 6 allows the engaging portion 22 to be elastically deformed to the left and right outside within a range that the socket 4 does not fall downward from the accommodating portion 21, so that the terminal portion 422 can be reliably brought into contact with the soldering position of the mounting surface 100a while adjusting the position of the terminal portion 422 in the left and right directions with respect to the soldering position of the mounting surface 100 a.

Then, the movable portion 52 of the housing 5 is pressed downward by the suction nozzle 200, and the spring portion 51 is elastically deformed to move downward, thereby pressing the socket 4 downward. As a result, the terminal portion 422 of the socket 4 is pressed against the conductive portion, not shown, of the mounting surface 100a of the board 100, and thus can be stably connected to the conductive portion.

Next, the terminal portions 422 and the protruding portions 412 of the socket 4 are soldered to the conductive portions, not shown, of the mounting surface 100a of the substrate 100, and the leg portions 34 of the pressing members 6 are soldered to the conductive portions, not shown, of the through holes 100b of the substrate 100, whereby the mounting of the electrical connector 11 and the substrate 100 is completed. At this time, since the socket 4 is free from the housing 5 as described above, the coplanarity of the terminal portion 422 with respect to the mounting surface 100a of the board 100 can be maintained in a good state without being affected by the housing 5.

As shown in fig. 18, the electrical connector 11 mounted on the substrate 100 by the above-described mounting method has the protruding portion 26 of the housing 5 protruding outward from the substrate 100. In this state, by providing the pressing member 6, the portion of the electrical connector 11 that overlaps the substrate 100 when viewed from above (in the state shown in fig. 18) has a center of gravity position. Thus, the electrical connector 11 can be mounted on the substrate 100 in a stable state.

Further, by providing the restricting portion 331 above the leg portion 34 soldered to the conductive portion of the through hole 100b, the engaging portion 22 can be reliably restricted from being elastically deformed to the left and right outside by the restricting portion 331 in a state where the electrical connector 11 is mounted on the mounting surface 100a of the substrate 100.

As described above, according to the present embodiment, the housing 5 includes the spring portion 51 and the movable portion 52 provided above the accommodating portion 21 and capable of pressing the socket 4 held by the engaging portion 22 in the accommodating portion 21 downward by elastic deformation, and thus, the effect of the first embodiment can be obtained, and the socket 4 can be stably mounted on the mounting surface 100a of the board 100.

In the present embodiment, when the electrical connector 11 is mounted on the mounting surface 100a, the movable portion 52 is pressed downward by the suction nozzle 200, but the present invention is not limited thereto, and the movable portion 52 may be pressed downward by a jig or the like other than the suction nozzle 200.

In the present embodiment, the pressing tool 6 is not provided with the outer side surface portion 36, but the present invention is not limited thereto, and the pressing tool 6 may be provided with the outer side surface portion 36.

In the present embodiment, the engaging portion 22 is restricted from being elastically deformed in the direction in which the receptacle 4 is detached from the accommodating portion 21 by the pressing tool 6, but the present invention is not limited thereto, and an attachment member other than the pressing tool 6 may be attached to the housing 5, and the engaging portion 22 may be restricted from being elastically deformed in the direction in which the receptacle 4 is detached from the accommodating portion 21 by the attachment member.

The electrical connector 12 of the present embodiment has a socket 4, a housing 7, a pressing member 8, and a slider 9.

The housing 7 is made of an insulating material such as resin, and includes a front wall 19, a protruding wall 20, a housing 21, an engaging portion 22, an abutting portion 23, a fitting portion 24, an insertion portion 25, a protruding portion 26, a rear wall 28, an inner top wall 29, an opening 30, a communication hole 71, and a flat portion 72.

The receiving portion 21 is concavely provided on the bottom surface, i.e., the lower surface, of the housing 7, and the rear end thereof communicates with the outside.

When the housing 7 has been mounted on the mounting surface 100a of the board 100, the abutment portion 23 abuts on the mounting surface 100a.

The insertion portion 25 is a through hole penetrating in the vertical direction around the housing portion 21, and is configured to allow the pressing tool 8 to be inserted therethrough.

When the housing 7 has been mounted on the mounting surface 100a of the board 100, the protruding portion 26 protrudes outward and forward from the board 100 (see fig. 17).

The rear wall 28 is provided at the rear end of the housing 7, and its center in the lateral direction is recessed forward.

The inner top wall 29 is provided above the housing 21 and faces the receptacle 4 held in the housing 21 with a space therebetween.

A communication hole 71 is provided to extend upward from the housing portion 21, an upper end of the communication hole 71 is opened to the outside, and the communication hole 71 holds the slider 9 movable in the up-down direction.

The flat portion 72 is provided around the communication hole 71 on the rear upper surface of the housing 7, and is flat in the front-rear direction and the left-right direction.

The pressing piece 8 is formed by bending a metal plate after punching the metal plate by press working, and is an attaching member attached to the housing 7 so as to fix the housing 7 to the substrate 100. The pressing tool 8 is inserted into the insertion portion 25 of the housing 7 and is mounted to the housing 7. The presser 8 includes a rear surface portion 32, an inner side surface portion 33, a leg portion 34, a front surface portion 35, a top surface portion 81, and a window 82.

The rear surface portion 32 is formed to be bent downward from the rear end of the top surface portion 81, and covers the rear wall portion 28.

The inner side surface portion 33 is formed to be bent rearward from the left and right ends of the front surface portion 35, is provided on the left and right sides of the top surface portion 81, and is inserted into the insertion portion 25.

The leg 34 protrudes downward from the insertion portion 25 and is located above the bottom surface of the case 7.

The front surface portion 35 is formed to be bent downward from the front end of the top surface portion 81 and inserted into the insertion portion 25.

The top surface portion 81 covers the flat portion 72.

The window 82 is a through hole provided in the substantially center of the top surface 81 and penetrating in the plate thickness direction, and exposes the upper end of the slider 9 held in the communication hole 71 to the outside.

The slider 9 is cylindrical and is held by the communication hole 71 so as to be movable in the up-down direction. The slider 9 can press the socket 4 downward by moving downward.

Method for manufacturing electric connector

Hereinafter, a method of manufacturing the electrical connector 12 according to the third embodiment of the present invention will be described in detail with reference to fig. 16 to 18.

First, the housing 7 is formed in advance using a resin material by injection molding or the like, and the metal plate is subjected to press working to form the pressing piece 8. In addition, the socket 4 manufactured by the existing method is ready.

Next, an insertion step of inserting the slider 9 into the communication hole 71 of the housing 7 from below and then inserting the socket 4 into the accommodating portion 21 of the housing 7 from the front of the protruding wall portion 20 from below is performed. At this time, the socket 4 is inserted into the accommodating portion 21 while the engaging portion 22 of the housing 7 is elastically deformed outward by the cover 43 of the socket 4. The following manufacturing method is the same as the manufacturing method of the electrical connector 1, and therefore, the description thereof is omitted.

In the completed state of the electrical connector 12, the engaging portion 22 is restricted from being elastically deformed outward and leftward by the restricting portion 331 of the inner side portion 33, whereby the receptacle 4 can be prevented from falling downward from the housing portion 21 before the electrical connector 12 is mounted on the substrate 100.

Mounting method of electric connector

Hereinafter, a method of mounting the electrical connector 12 according to the third embodiment of the present invention will be described in detail with reference to fig. 16 to 18.

The slider 9 of the electrical connector 12 manufactured by the above manufacturing method, which is exposed to the outside from the window 82 of the pressing member 8, is sucked by the suction nozzle 200 of the mounter, and the electrical connector 12 is transferred to the mounting surface 100a of the substrate 100. At this time, the engagement claw 221 of the engagement portion 22 engages with the engaged portion 432 of the cover 43, whereby the terminal portion 422 of the receptacle 4 is positioned below the contact portion 23 of the housing 7. The socket 4 is opposed to the inner ceiling wall 29 of the housing 7 with a space therebetween.

Then, the leg portion 34 of the pressing member 8 of the electrical connector 12 is inserted into the through hole 100b of the substrate 100 from above.

By inserting the leg 34 into the through hole 100b, first, the terminal portion 422 of the contact 42 of the receptacle 4 and the protruding portion 412 of the shield shell 41 are brought into contact with the mounting surface 100a, and then the contact portion 23 of the housing 7 is brought into contact with the mounting surface 100a.

Before the terminal portion 422 and the protruding portion 412 are brought into contact with the mounting surface 100a, the interval in the up-down direction between the lower end portion of the contact portion 23 and the upper end portion of the locking claw 221 is smaller than the interval in the up-down direction between the lower end portion of the engaged portion 432 of the receptacle 4 and the welding surface of the terminal portion 422, and the welding surface of the terminal portion 422 and the lower end portion of the protruding portion 412 are located below the lower end portion of the contact portion 23. In this state, the terminal portion 422 and the protruding portion 412 are brought into contact with the mounting surface 100a, so that the engaged portion 432 moves upward relative to the locking claw portion 221 and moves away from the locking claw portion 221, and the receptacle 4 moves upward relative to the housing 7 in the accommodating portion 21. Thereby, the socket 4 is free from the housing 7.

Further, by relatively moving the socket 4 upward with respect to the housing 7, the terminal portion 422 of the socket 4 is located at substantially the same position as the contact portion 23 of the housing 7 in the up-down direction. Further, the socket 4 moves upward relative to the housing 7, thereby being opposed to the inner wall 29 of the housing 7 so as to be closer to the inner wall 29 than before being attached to the attachment surface 100a, and pushing up the slider 9.

The present invention is configured such that the soldering surface of the terminal portion 422 of the receptacle 4 is located below the lower end portion of the contact portion 23 of the housing 7 before the electrical connector 12 is mounted on the substrate 100, but the present invention is not limited thereto, and the soldering surface of the terminal portion 422 and the lower end portion of the contact portion 23 may be located at the same height in the vertical direction. In this case, even after the terminal portion 422 is brought into contact with the substrate 100, the locking claw portion 221 is not completely separated from the engaged portion 432, and the receptacle 4 is similarly free from the influence of the housing 7 as long as the self weight of the receptacle 4 is not applied to the locking claw portion 221 via the engaged portion 432.

Further, the restricting portion 331 of the pressing member 8 allows the engaging portion 22 to be elastically deformed to the left and right outside within a range that the socket 4 does not fall downward from the accommodating portion 21, so that the terminal portion 422 can be reliably brought into contact with the soldering position of the mounting surface 100a while adjusting the position of the terminal portion 422 in the left and right directions with respect to the soldering position of the mounting surface 100 a.

Then, the slider 9 is pushed downward by the suction nozzle 200, and thereby moves downward in the communication hole 71 to push the socket 4 downward. As a result, the terminal portion 422 of the socket 4 is pressed against the conductive portion, not shown, of the mounting surface 100a of the board 100, and thus can be stably connected to the conductive portion.

Next, the terminal portions 422 and the protruding portions 412 of the socket 4 are soldered to the conductive portions, not shown, of the mounting surface 100a of the substrate 100, and the leg portions 34 of the pressing members 8 are soldered to the conductive portions, not shown, of the through holes 100b of the substrate 100, whereby the mounting of the electrical connector 12 and the substrate 100 is completed. At this time, since the socket 4 is in a free state with respect to the housing 7 as described above, the coplanarity of the terminal portion 422 with respect to the mounting surface 100a of the board 100 can be maintained in a good state without being affected by the housing 7.

As shown in fig. 21, the electrical connector 12 mounted on the substrate 100 by the above-described mounting method has the protruding portion 26 of the housing 7 protruding outward from the substrate 100. In this state, by providing the pressing member 8, the portion of the electrical connector 12 that overlaps the substrate 100 when viewed from above (in the state shown in fig. 21) has a center of gravity position. Thus, the electrical connector 12 can be mounted on the substrate 100 in a stable state.

Further, by providing the restricting portion 331 above the leg portion 34 soldered to the conductive portion of the through hole 100b, the engaging portion 22 can be reliably restricted from being elastically deformed to the left and right outside by the restricting portion 331 in a state where the electrical connector 12 is mounted on the mounting surface 100a of the substrate 100.

As described above, according to the present embodiment, the housing 7 includes: the communication hole 71 is provided so as to extend upward from the housing portion 21, the upper end of the communication hole 71 is opened to the outside, and the communication hole 71 holds the slider 9 so as to be movable in the up-down direction, and the slider 9 is movable downward in the communication hole 71 to press down the socket 4 held by the engaging portion 22 in the housing portion 21, whereby the effect of the first embodiment described above can be obtained, and the socket 4 can be stably attached to the attachment surface 100a of the board 100.

In the present embodiment, when the electrical connector 12 is mounted on the mounting surface 100a, the slider 9 is pressed downward by the suction nozzle 200, but the present invention is not limited thereto, and the slider 9 may be pressed downward by a jig or the like other than the suction nozzle 200.

In the present embodiment, the engaging portion 22 is restricted from being elastically deformed in the direction in which the receptacle 4 is detached from the accommodating portion 21 by the pressing tool 8, but the present invention is not limited thereto, and an attachment member other than the pressing tool 8 may be attached to the housing 7, and the engaging portion 22 may be restricted from being elastically deformed in the direction in which the receptacle 4 is detached from the accommodating portion 21 by the attachment member.

The kind, arrangement, number, and the like of the members of the present invention are not limited to the above-described embodiments, and of course, the constituent elements thereof may be appropriately replaced with constituent elements that can exert equivalent effects, and the like, without departing from the scope of the present invention.

Specifically, in the first to third embodiments described above, the receptacle 4 is held in the housing 21, but the present invention is not limited to this, and a connector having a different structure from the receptacle 4 may be held in the housing 21.

In the first to third embodiments, the receptacle 4 held in the housing 21 is movable in the up-and-down direction, but the present invention is not limited thereto, and the receptacle 4 held in the housing 21 may be movable not only in the up-and-down direction but also in the front-and-rear direction. In this case, the receptacle 4 held in the housing 21 can be self-aligned inside the housing 2, the housing 5, or the housing 7.

In the first to third embodiments, the restricting portion 311 is provided above the leg portion 34, but the present invention is not limited thereto, and the restricting portion 311 may be provided in the vicinity of the leg portion 34 other than above the leg portion 34, such as between the pair of leg portions 34. In this case, the engaging portion 22 can be reliably restrained from being elastically deformed outward and leftward by the restricting portion 331.
