Description

Technical Field

[0001] The present invention relates to an electrical connector having a housing and a socket having a mounting surface mounted on a substrate, a method for manufacturing the electrical connector, and a method for mounting the electrical connector. Background Technology

[0002] Previously, as electrical connectors for automotive applications, there was a known type of electrical connector with a structure that held the socket inside a housing such as an outer housing.

[0003] Patent Document 1 discloses an electrical connector comprising: a pair of arms for clamping a socket by elastic force; and a locking portion having a locking surface at the top of the arms, wherein the locking surface is parallel to a plane orthogonal to the direction of insertion into the socket. Furthermore, the electrical connector of Patent Document 1 has a pressing surface at the corner formed by the locking surface and the arms, which presses the socket toward the insertion direction when the arms clamp it. This allows the socket to be held in place within the housing without wobbling.

[0004] Furthermore, the electrical connector in Patent Document 1 requires maintaining the flatness (hereinafter referred to as "coplanarity") of the terminal portion of the socket relative to the mounting surface of the substrate. Moreover, the electrical connector in Patent Document 1 requires maintaining coplanarity by taking into account the positional accuracy of the socket's fixed position and the housing's connection position with the substrate. For example, when the terminal spacing of the socket is 0.8 mm, a coplanarity of 0.15 mm or less is required.

[0005] However, in Patent Document 1, the narrower the spacing between the terminals of the socket, the more stringent the required coplanarity becomes. Therefore, it is impossible to meet the required coplanarity by considering the positional accuracy of the socket's fixed position and the connection position of the housing to the substrate. For example, Patent Document 1 has the following problem: when the terminal spacing of the socket is 0.5 mm or less, the required coplanarity of the socket is 0.08 mm or less, thus making it impossible to meet the required coplanarity.

[0008] Patent Document 1: Japanese Patent Application Publication No. 2016-18720 Summary of the Invention

[0009] The problem that the invention aims to solve

[0010] The purpose of this invention is to provide an electrical connector, a method for manufacturing the electrical connector, and a method for installing the electrical connector, which can maintain the coplanarity of the terminals of the socket in a good state even when the spacing between the terminals is narrow.

[0011] Solution for solving the problem

[0012] The electrical connector of the present invention has a housing and a socket mounted on a mounting surface of a substrate. The housing includes: a receiving portion disposed on a bottom surface opposite to the mounting surface, and accommodating the socket in a state in which the socket is exposed to the outside; a retaining portion holding the socket in the receiving portion; an abutting portion abutting against the mounting surface; an inner top wall portion facing the socket above the socket held in the receiving portion by the retaining portion; and a pressing portion protruding downward from the inner top wall portion, and having a gap between the pressing portion and the socket held in the receiving portion by the retaining portion. The socket includes a terminal portion soldered to the mounting surface. When the socket is held in the receiving portion by the retaining portion, the terminal portion is located at the same height as the abutting portion or below the abutting portion, and the socket is movable upward. When the abutting portion has abutted against the mounting surface, the socket is pressed against the mounting surface by the pressing portion.

[0013] The present invention discloses a method for manufacturing an electrical connector having a housing and a socket having a mounting surface mounted on a substrate. The method includes: an insertion step in which the socket is inserted into a receiving portion provided on the bottom surface of the housing opposite to the mounting surface; and a holding step in which the socket, inserted into the receiving portion during the insertion step, is held in the receiving portion with its externally exposed state via a holding portion of the housing, thereby positioning the terminal portion of the socket soldered to the mounting surface at the same height as or below an abutting portion of the housing that abuts the mounting surface, and allowing the socket to move upward. In the holding step, when the abutting portion has abutted the mounting surface, the socket can be pressed against the mounting surface by a pressing portion, wherein the pressing portion protrudes downward from an inner top wall portion of the housing and has a gap between the pressing portion and the socket, and the inner top wall portion faces the socket above the socket held in the receiving portion by the holding portion.

[0014] The present invention provides a method for mounting an electrical connector having a housing and a socket on a mounting surface of a substrate. The socket is held exposed to the outside by a retaining portion of the housing in a receiving portion located on the bottom surface of the housing opposite the mounting surface. This causes the terminal portion of the socket soldered to the mounting surface to be positioned at the same height as or below an abutting portion of the housing that abuts the mounting surface, and allows the socket to move upwards. An inner top wall portion of the housing faces the socket above the socket held in the receiving portion by the retaining portion. A pressing portion protruding downwards from the inner top wall portion has a gap between it and the socket. In this state, when the abutting portion abuts against the mounting surface, the pressing portion presses the socket against the mounting surface, and the terminal portion is soldered to the mounting surface.

[0015] After the terminal portion of the socket abuts against the mounting surface of the substrate, the socket can be moved upward relative to the housing while the abutting portion of the housing abuts against the mounting surface, and the terminal portion of the socket can be soldered to the mounting surface without being affected by the housing.

[0016] Invention Effects

[0017] According to the present invention, even if the spacing between the terminals of the socket is narrow, the coplanarity of the terminals of the socket can be maintained in a good state. Attached Figure Description

[0043] (First Implementation)

[0044] <Structure of Electrical Connectors>

[0045] The following is for reference Figures 1 to 14 The structure of the electrical connector 1 according to the first embodiment of the present invention will be described in detail.

[0046] The electrical connector 1 of this embodiment has a case 2, a hold-down member 3, and a socket 4.

[0047] The housing 2 is formed of an insulating material such as resin, and includes a pressing part 18, a front wall part 19, a protruding wall part 20, a receiving part 21, a locking part 22, an abutting part 23, a fitting part 24, a through part 25, a protruding part 26, a flat part 27, a rear wall part 28, an inner top wall part 29, and an opening part 30. The front wall part 19, the protruding wall part 20, and the locking part 22 are configured to retain the socket 4 in the holding part of the receiving part 21 by restricting the socket 4 received in the receiving part 21 from moving forward, backward, left, right, and downward.

[0048] like Figure 5 As shown, the pressing part 18 protrudes downward from the inner top wall part 29 between the protrusion 412 and the terminal part 422 described later in the socket 4. The pressing part 18 is positioned opposite the socket 4 with a gap between it and the socket 4 held in the receiving part 21. When the housing 2 and the socket 4 are mounted on the mounting surface 100a of the base plate 100, the pressing part 18 abuts against the socket 4.

[0049] The front wall portion 19 is located in front of the receiving portion 21, restricting the forward movement of the socket 4 held in the receiving portion 21.

[0050] The protruding wall portion 20 is located behind the engaging portion 22, restricting the rearward movement of the socket 4 housed in the receiving portion 21.

[0051] The receiving portion 21 is provided on the bottom surface, i.e., the lower surface, of the housing 2 opposite to the mounting surface 100a of the substrate 100, and its rear end communicates with the outside. The receiving portion 21 accommodates the socket 4 in a state where the socket 4 is exposed to the outside.

[0052] A pair of engaging portions 22, serving as elastic parts, are provided on the inner walls of the left and right sides of the receiving portion 21. Each engaging portion 22 has an inwardly protruding locking claw 221 at its lower end. The engaging portions 22 can elastically deform in the left-right direction between the insertion portion 25 and the receiving portion 21. The locking claw 221 of the engaging portion 22 engages with the engaging portion 432 of the cover 43 of the socket 4 (described later) to restrict the downward movement of the socket 4.

[0053] The abutting portion 23 is provided at the lower end of the left and right side walls at the front end of the receiving portion 21. When the housing 2 has been mounted on the mounting surface 100a of the substrate 100, the abutting portion 23 abuts against the mounting surface 100a.

[0054] The fitting part 24 is a cylindrical part provided on the protrusion 26 and its front end is open to the outside, and can be fitted with the opposite connector (not shown).

[0055] The insertion part 25 is a through hole that extends along the vertical direction around the receiving part 21, through which the clamping member 3 is inserted.

[0056] When the housing 2 has been mounted on the mounting surface 100a of the substrate 100, the protrusion 26 protrudes outward and forward from the substrate 100 (see reference). Figure 7 ).

[0057] The flat portion 27 is provided on the upper surface of the rear of the housing 2 and is flat along the front-back direction and the left-right direction.

[0058] The rear wall portion 28 is located at the rear end of the housing 2, and its center in the left-right direction is recessed forward.

[0059] The inner top wall portion 29 is located above the receiving portion 21.

[0060] The opening 30 is provided on the front wall portion 19, so that the receiving portion 21 communicates with the fitting portion 24 (see reference). Figure 5 ).

[0061] The clamping member 3 is formed by punching a metal sheet and then bending the metal sheet. It is a mounting member that is attached to the housing 2 to fix the housing 2 to the base plate 100. The clamping member 3 is inserted into the insertion part 25 of the housing 2 and is assembled to the housing 2. The clamping member 3 has a top part 31, a rear part 32, an inner side part 33, a foot part 34, a front part 35, and an outer side part 36.

[0062] The top part 31 covers the flat part 27.

[0063] The rear surface portion 32 is formed to bend downward from the rear end of the top portion 31, covering the rear wall portion 28.

[0064] The inner side portion 33 is formed to bend rearward from the left and right ends of the front surface portion 35 and is provided on the left and right sides of the top surface portion 31, and inserted into the insertion portion 25. Each inner side portion 33 has a limiting portion 331 near the front foot 34 of one of the pair of feet 34, i.e., above it.

[0065] The limiting part 331 is disposed opposite to the locking claw part 221 on the left and right outer sides of the locking claw part 221. The limiting part 331, on the one hand, restricts the elastic deformation of the engaging part 22 to the left and right outer sides that would cause the socket 4 to detach from the receiving part 21 downwards; on the other hand, it allows the engaging part 22 to elastically deform to the left and right outer sides within a range that will not cause the socket 4 to detach from the receiving part 21 downwards. Here, the left and right outer sides are the directions in which the socket 4 would detach from the receiving part 21 downwards.

[0066] The feet 34, which serve as welding parts, extend downward from the lower ends of the left and right inner side panels 33, respectively. A pair of feet 34 are provided on each inner side panel 33 at intervals in the front-rear direction. The feet 34 protrude downward from the insertion portion 25 and are located above the bottom surface of the housing 2.

[0067] The front surface portion 35 is formed to bend downward from the front end of the top surface portion 31 and insert into the insertion portion 25.

[0068] The outer side portion 36 is formed to bend forward from the left and right ends of the rear surface portion 32, covering the rear end side of the left side face and the rear end side of the right side face of the housing 2.

[0069] The socket 4 has a shielding shell 41, contacts 42, a cover 43 and a housing 44.

[0070] The shielding shell 41 is formed by punching a metal plate using a stamping process and then bending the metal plate. It has a mating portion 411 that opens forward to engage with a connector on the opposite side (not shown). The shielding shell 41 has a protrusion 412 that protrudes downward from the bottom surface and is welded to the mounting surface 100a when the socket 4 is mounted on the mounting surface 100a of the substrate 100.

[0071] like Figure 3 As shown, a protrusion 412 is provided between the terminal portion 422 and the abutment portion 23, and a pair of left and right protrusions 412 are provided at the joint formed when the metal plate constituting the shielding shell 41 is bent. It should be noted that the protrusions 412 are welded to the mounting surface 100a, but are not limited thereto, and may not be welded but simply abut against the mounting surface 100a.

[0072] The contact 42 is formed of a conductive material and is assembled onto the base 44. The contact 42 includes: a connecting portion 421, which connects to a conductive portion of a counterpart connector (not shown); and a terminal portion 422, which is soldered to the mounting surface 100a of the substrate 100. With the locking claw 221 of the engaging portion 22 engaged with the engaging portion 432 of the cover 43, thus holding the socket 4 in the receiving portion 21, the terminal portion 422 is located below the abutting portion 23 (see reference). Figure 14 ).

[0073] The cover 43 is formed by punching a metal sheet using a stamping process and then bending the metal sheet, and is assembled onto the shielding shell 41 in an insulated state from the contact 42. The cover 43 includes: a foot 431, a conductive portion (not shown) connected to the mounting surface 100a of the substrate 100; and a locking portion 432, which engages with the locking claw portion 221 of the locking portion 22. The cross-section of the locking portion 432 has a width equal to the thickness of the metal sheet constituting the cover 43.

[0074] The base 44 is formed of an insulating material such as resin and is covered by a shielding shell 41. The base 44 holds the contact 42 in a state of insulation from the shielding shell 41 and the cover 43.

[0075] The socket 4 with the above structure is positioned opposite the pressing part 18 of the housing 2 in a spaced manner while held in the receiving part 21, thereby allowing it to move upward relative to the housing 2.

[0076] <Manufacturing Method of Electrical Connectors>

[0077] The following is for reference Figures 1 to 13 The manufacturing method of the electrical connector 1 according to the first embodiment of the present invention will be described in detail.

[0078] First, the housing 2 is formed using resin material and injection molding or the like, and the clamping part 3 is formed by stamping a metal sheet. Then, a socket 4 manufactured using existing methods is prepared. At this time, a socket 4 with a number or spacing of terminal portions 422 appropriate to the application can be selected.

[0079] Next, the insertion process is performed to insert the socket 4 into the receiving portion 21 of the housing 2 from the front and bottom of the protruding wall portion 20. At this time, the socket 4 is inserted into the receiving portion 21 while the locking portion 22 of the housing 2 is elastically deformed to the left and right by the cover 43 of the socket 4.

[0080] Next, the following holding process is performed: the socket 4 is inserted into the receiving portion 21 from below until the cover 43 of the socket 4 passes the engaging portion 432. The elastic restoring force of the engaging portion 22 of the housing 2 causes the locking claw 221 of the engaging portion 22 to engage with the engaging portion 432 of the cover 43, thus holding the socket 4 in the receiving portion 21. At this time, the socket 4 is held in the receiving portion 21 in a state where downward movement is restricted by the locking claw 221 of the engaging portion 22, rearward movement is restricted by the protruding wall portion 20, and forward movement is restricted by the front wall portion 19.

[0081] Next, the foot 34 of the clamping member 3 is inserted from above into the insertion part 25 of the housing 2, and then inserted into the inner side part 33 and the front surface part 35.

[0082] Then, the inner side portion 33 and the front surface portion 35 of the clamping member 3 are further inserted into the insertion portion 25, whereby the top portion 31 abuts against and covers the flat portion 27, the rear surface portion 32 covers the rear wall portion 28, and the outer side portion 36 covers the rear end side of the left side portion and the rear end side of the right side portion of the housing 2. Thus, the electrical connector 1 is completed.

[0083] With the electrical connector 1 in the completed state, the locking portion 22 is restricted from elastically deforming to the left and right by the limiting portion 331 of the inner side portion 33, thereby preventing the socket 4 from falling off the receiving portion 21 downwards before the electrical connector 1 is installed on the mounting surface 100a of the substrate 100.

[0084] In particular, the engagement width of the engaged portion 432 that engages with the locking claw portion 221 is only the thickness of the metal plate constituting the cover 43. The locking claw portion 221 and the engaged portion 432 are in a very shallow engagement state. Therefore, without the restriction portion 331 to limit the elastic deformation of the engaged portion 22 to the left and right, when an external force such as an impact is applied to the electrical connector 1 before it is installed on the substrate 100, the engagement between the locking claw portion 221 and the engaged portion 432 is easy to disengage, and the socket 4 will fall off the housing 2.

[0085] In contrast, in this embodiment, the locking portion 22 is restricted from elastically deforming to the left and right sides by the limiting portion 331 of the clamping member 3. Thus, even when the locking claw portion 221 and the locked portion 432 are in a very shallow engagement state, it can prevent the locking portion 22 from elastically deforming to the left and right sides and the socket 4 from falling off the housing 2 when an external force such as an impact is applied to the electrical connector 1.

[0086] <Installation Method of Electrical Connectors>

[0087] The following is for reference Figures 1 to 15 The installation method of the electrical connector 1 according to the first embodiment of the present invention will be described in detail.

[0088] The top surface 31 of the electrical connector 1, manufactured by the above method, is adsorbed using the suction nozzle of an installation machine (not shown), and the electrical connector 1 is transferred to the mounting surface 100a of the substrate 100. At this time, the locking claw 221 of the engaging portion 22 engages with the engaging portion 432 of the cover 43, and the terminal portion 422 of the socket 4 is... Figure 14 The position shown is located at a distance H1 below the contact portion 23 of the housing 2. Furthermore, the socket 4 is positioned opposite the pressing portion 18 protruding downward from the inner top wall portion 29 of the housing 2 with a gap R1.

[0089] Next, the foot 34 of the clamping member 3 of the electrical connector 1 is inserted from above into the through hole 100b of the substrate 100.

[0090] By inserting the foot 34 through the through hole 100b, firstly, the terminal portion 422 of the contact 42 of the socket 4 and the protrusion 412 of the shield 41 abut against the mounting surface 100a, and then the abutting portion 23 of the housing 2 abuts against the mounting surface 100a.

[0091] Before the terminal portion 422 and the protrusion 412 abut against the mounting surface 100a, as Figure 14As shown, the vertical distance H2 between the lower end of the abutment portion 23 and the upper end of the locking claw portion 221 is less than the vertical distance H3 between the lower end of the engaged portion 432 of the socket 4 and the welding surface of the terminal portion 422 (H2 < H3). The welding surface of the terminal portion 422 and the lower end of the protrusion 412 are located H1 below the lower end of the abutment portion 23. In this state, the terminal portion 422 and the protrusion 412 abut against the mounting surface 100a, thereby causing the engaged portion 432 to move upward relative to the locking claw portion 221 and move away from the locking claw portion 221. The socket 4 moves upward relative to the housing 2 within the receiving portion 21 by an amount of distance (H3 - H2 = H1). Thus, the socket 4 becomes a free state unaffected by the housing 2.

[0092] Furthermore, the socket 4 moves upward relative to the housing 2, thereby... Figure 15 As shown, in the vertical direction, the welding surface of the terminal portion 422 and the lower end of the abutment portion 23 are located at approximately the same position (H1≈0). Furthermore, since the interval R1 is approximately the same as the distance H1 (R1≈H1), the socket 4 abuts against the pressing portion 18 (R1=0) by moving upward relative to the housing 2, and is pressed from above by the pressing portion 18 towards the mounting surface 100a.

[0093] It should be noted that, in this invention, before the electrical connector 1 is installed on the substrate 100, the soldering surface of the terminal portion 422 of the socket 4 is located below the lower end of the abutment portion 23 of the housing 2. However, this is not a limitation; it is also possible that the soldering surface of the terminal portion 422 and the lower end of the abutment portion 23 are at the same height in the vertical direction (H1 = 0 and H2 = H3). In this case, even after the terminal portion 422 and the protrusion 412 abut against the substrate 100, if the locking claw portion 221 is not completely separated from the engaged portion 432, as long as the weight of the socket 4 is not applied to the locking claw portion 221 through the engaged portion 432, the socket 4 will also be in a free state unaffected by the housing 2.

[0094] Furthermore, the limiting portion 331 of the clamping member 3 allows the engaging portion 22 to elastically deform to the left and right outside within a range that will not cause the socket 4 to fall off the receiving portion 21 downwards. Therefore, the terminal portion 422 can be reliably abutted against the welding position of the mounting surface 100a while adjusting the position of the terminal portion 422 in the left and right direction relative to the welding position of the mounting surface 100a.

[0095] Next, the terminal portion 422 and protrusion 412 of the socket 4 are soldered to a conductive portion (not shown) on the mounting surface 100a of the substrate 100, and the foot portion 34 of the clamping member 3 is soldered to a conductive portion (not shown) on the through hole 100b of the substrate 100, thereby completing the installation of the electrical connector with the substrate 100. At this time, as described above, the socket 4 is in a state where the engagement between the engaging portion 432 and the locking claw portion 221 has been released, so 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 the influence of the housing 2.

[0096] Furthermore, the socket 4 is pressed against the mounting surface 100a from above by the pressing part 18, thus preventing the terminal part 422 and the protrusion 412 from lifting off the mounting surface 100a. At this time, the socket 4 is pressed against the mounting surface 100a from above by the pressing part 18 between the terminal part 422 abutting against the mounting surface 100a and the protrusion 412 abutting against the mounting surface 100a, so that it can be installed in a parallel state relative to the mounting surface 100a without tilting in the front-to-back direction.

[0097] The electrical connector 1, which is installed on the substrate 100 using the above-described mounting method, is as follows: Figure 7 As shown, the protrusion 26 of the housing 2 protrudes outward from the base plate 100. In this state, by providing the clamping member 3, the electrical connector 1, when viewed from above ( Figure 7 In the state shown, the portion overlapping with the substrate 100 has a center of gravity position. As a result, the electrical connector 1 can be mounted on the substrate 100 in a stable state.

[0098] Furthermore, by providing a limiting part 331 above the foot 34 of the conductive part soldered to the through hole 100b, even when the limiting part 331 is pressed to the left and right by the engaging part 22, the elastic deformation of the engaging part 22 to the left and right can be reliably limited by the limiting part 331 when the electrical connector 1 is mounted on the mounting surface 100a of the substrate 100.

[0099] Thus, according to this embodiment, in the electrical connector 1 having a housing 2 and a socket 4 mounted on a mounting surface 100a of a substrate 100, the housing 2 includes: a receiving portion 21 provided on the bottom surface opposite to the mounting surface 100a, which receives the socket 4 in a state where the socket 4 is exposed to the outside; a front wall portion 19, a protruding wall portion 20, and a locking portion 22, which hold the socket 4 in the receiving portion 21; and an abutting portion 23 abutting against the mounting surface 100a. The socket 4 has terminal portions 422 soldered to the mounting surface 100a. When the socket 4 is held in the receiving portion 21 by the front wall portion 19, the protruding wall portion 20, and the locking portion 22, the terminal portions 422 are located at the same height as the abutting portion 23 or below the abutting portion 23, and the socket 4 can move upward. Therefore, even if the spacing of the terminal portions 422 of the socket 4 is narrow, the coplanarity of the terminal portions 422 of the socket 4 can be maintained in a good state.

[0100] Furthermore, according to this embodiment, the device includes: a housing 2, mounted on a mounting surface 100a of a substrate 100; a socket 4, mounted on the mounting surface 100a in a state of being accommodated in the housing 2; and a clamping member 3, attached to the housing 2. The housing 2 includes: a receiving portion 21 for accommodating the socket 4; and a front wall portion 19, a protruding wall portion 20, and a locking portion 22 for holding the socket 4 in the receiving portion 21. The holding portion includes: a locking portion 22 for holding the socket 4 in the receiving portion 21 by elastic force and being elastically deformable; and a clamping member 3 for limiting the locking portion 22 from elastically deforming in the direction that causes the socket 4 to fall off the receiving portion 21, thereby preventing the socket 4 from falling off the housing 2.

[0101] Furthermore, according to this embodiment, by fixing the housing 2 to the base plate 100 with a clamping member 3, the elastic deformation of the engaging portion 22 in the direction that causes the socket 4 to detach from the receiving portion 21 is restricted. Thus, the clamping member 3 can serve as both a member for fixing the housing 2 to the base plate 100 and a member for restricting the elastic deformation of the engaging portion 22 in the direction that causes the socket 4 to detach from the receiving portion 21, thereby suppressing the increase in the number of parts.

[0102] It should be noted that in this embodiment, the clamping member 3 is used to limit the elastic deformation of the engaging portion 22 in the direction that causes the socket 4 to fall off from the receiving portion 21. However, it is not limited to this. Alternatively, a mounting member other than the clamping member 3 can be mounted on the housing 2, and the mounting member can be used to limit the elastic deformation of the engaging portion 22 in the direction that causes the socket 4 to fall off from the receiving portion 21.

[0103] (Second Implementation)

[0104] <Structure of Electrical Connectors>

[0105] The following is for reference Figures 16 to 19 The structure of the electrical connector 11 according to the second embodiment of the present invention will be described in detail.

[0106] It should be noted that, in Figures 16 to 19 In the middle, to and Figures 1 to 15 Parts with the same structure are labeled with the same reference numerals, and their descriptions are omitted.

[0107] The electrical connector 11 of this embodiment has a socket 4, a housing 5, and a clamping member 6.

[0108] The housing 5 is formed of an insulating material such as resin, and includes a front wall portion 19, a protruding wall portion 20, a receiving portion 21, a locking portion 22, a contact portion 23, a fitting portion 24, a through portion 25, a protruding portion 26, an inner top wall portion 29, an opening portion 30, a spring portion 51, a movable portion 52, and a rear wall portion 53. The spring portion 51 and the movable portion 52 constitute a press spring portion.

[0109] The receiving part 21 is recessed on the bottom surface, i.e. the lower surface, of the housing 5, and its rear end is connected to the outside.

[0110] The insertion part 25 is a through hole that extends along the vertical direction around the receiving part 21, through which the clamping member 6 is inserted.

[0111] When the housing 5 has been mounted on the mounting surface 100a of the substrate 100, the protrusion 26 protrudes outward and forward from the substrate 100.

[0112] The inner top wall portion 29 is located above the receiving portion 21 and is positioned opposite the socket 4 held in the receiving portion 21 in a spaced manner.

[0113] The spring part 51 connects the movable part 52 and the rear wall part 53. When the movable part 52 is pressed downward, the spring part 51 elastically deforms to allow the movable part 52 to move downward, and when the downward pressing force on the movable part 52 is released, the movable part 52 moves upward by elastic restoring force.

[0114] The movable part 52 is provided above the receiving part 21 and is positioned opposite the socket 4 held in the receiving part 21 at a distance. When the movable part 52 is pressed downward, it moves downward to press the socket 4 held in the receiving part 21 downward, and when the downward pressing force is released, it moves upward to release the downward pressing of the socket 4 held in the receiving part 21.

[0115] The rear wall portion 53 is located at the rear end of the housing 5, on the left and right sides of the movable portion 52, and is recessed forward toward the movable portion 52.

[0116] The clamping member 6 is formed by bending a metal sheet after punching it using a stamping process. It is a mounting member that is attached to the housing 5 to fix the housing 5 to the base plate 100. The clamping member 6 is inserted into the insertion part 25 of the housing 5 and is assembled to the housing 5. The clamping member 6 has a rear surface part 32, an inner side part 33, a foot part 34, a front surface part 35, a top part 61, and a window part 62.

[0117] The rear surface portion 32 is formed to bend downward from the rear end of the top portion 61, covering the rear end of the movable portion 52 and the rear wall portion 53.

[0118] The inner side portion 33 is formed to bend backward from the left and right ends of the front surface portion 35 and is provided on the left and right sides of the top surface portion 61, and is inserted into the insertion portion 25.

[0119] The foot 34 protrudes downward from the insertion part 25 and is located above the bottom surface of the housing 5.

[0120] The front surface portion 35 is formed to bend downward from the front end of the top surface portion 61 and insert into the insertion portion 25.

[0121] The top part 61 covers the upper end of the spring part 51 and the movable part 52.

[0122] The window portion 62 is a through hole located approximately in the center of the top portion 61, extending along the thickness direction of the plate, so that a portion of the movable portion 52 is exposed to the outside.

[0123] In the electrical connector 11 with the above structure, the locking portion 22 is restricted from elastically deforming to the left and right outward by the limiting portion 331 of the inner side portion 33, thereby preventing the socket 4 from falling off the receiving portion 21 downward before the electrical connector 11 is installed on the substrate 100.

[0124] It should be noted that the manufacturing method of the electrical connector 11 in this embodiment is the same as the manufacturing method of the electrical connector 1, so its description is omitted.

[0125] <Installation Method of Electrical Connectors>

[0126] The following is for reference Figures 16 to 19 The installation method of the electrical connector 11 according to the second embodiment of the present invention will be described in detail.

[0127] The suction nozzle 200 of the mounting machine is used to suction the upper surface of the movable part 52 of the housing 5, which protrudes from the window 62 of the clamping member 6 of the electrical connector 11, and the electrical connector 11 is transferred to the mounting surface 100a of the substrate 100. At this time, the locking claw 221 of the locking part 22 engages with the locking part 432 of the cover 43, and the terminal part 422 of the socket 4 is located below the abutting part 23 of the housing 5. In addition, the socket 4 is positioned at a distance from the inner top wall part 29 and the movable part 52 of the housing 5.

[0128] Next, the foot 34 of the clamping member 6 of the electrical connector 11 is inserted from above into the through hole 100b of the substrate 100.

[0129] By inserting the foot 34 through the through hole 100b, firstly, the terminal portion 422 of the contact 42 of the socket 4 and the protrusion 412 of the shield 41 abut against the mounting surface 100a, and then, the abutting portion 23 of the housing 5 abuts against the mounting surface 100a.

[0130] Before the terminal portion 422 and the protrusion 412 abut against the mounting surface 100a, the vertical distance between the lower end of the abutting portion 23 and the upper end of the locking claw portion 221 is smaller than the vertical distance between the lower end of the engaged portion 432 of the socket 4 and the welding surface of the terminal portion 422. The welding surface of the terminal portion 422 and the lower end of the protrusion 412 are located below the lower end of the abutting portion 23. By abutting the terminal portion 422 and the protrusion 412 against the mounting surface 100a in this state, the engaged portion 432 moves upward relative to the locking claw portion 221, thereby moving away from the locking claw portion 221, and the socket 4 moves upward relative to the housing 5 within the receiving portion 21. Thus, the socket 4 becomes a free state unaffected by the housing 5.

[0131] Furthermore, by moving the socket 4 upward relative to the housing 5, the terminal portion 422 of the socket 4 is positioned approximately at the same location as the abutment portion 23 of the housing 5 in the vertical direction. Additionally, by moving the socket 4 upward relative to the housing 5, it is positioned opposite the inner top wall portion 29 and the movable portion 52 of the housing 5, closer to them than before it was mounted on the mounting surface 100a.

[0132] It should be noted that, in this invention, the soldering surface of the terminal portion 422 of the socket 4 is located below the lower end of the abutment portion 23 of the housing 5 before the electrical connector 11 is installed on the substrate 100. However, this is not a limitation; the soldering surface of the terminal portion 422 and the lower end of the abutment portion 23 may also be at the same height in the vertical direction. In this case, even if the locking claw portion 221 and the engaged portion 432 are not completely separated after the terminal portion 422 abuts against the substrate 100, the socket 4 will remain in a free state unaffected by the housing 5, as long as the weight of the socket 4 is not exerted on the locking claw portion 221 via the engaged portion 432.

[0133] Furthermore, the limiting portion 331 of the clamping member 6 allows the engaging portion 22 to elastically deform to the left and right outside within a range that will not cause the socket 4 to fall off the receiving portion 21 downwards. Therefore, the terminal portion 422 can be reliably abutted against the welding position of the mounting surface 100a while adjusting the position of the terminal portion 422 in the left and right direction relative to the welding position of the mounting surface 100a.

[0134] Next, the movable part 52 of the housing 5 is pressed downward by the suction nozzle 200, thereby causing the spring part 51 to elastically deform and move downward, pressing the socket 4 downward. As a result, the terminal part 422 of the socket 4 is pressed against the conductive part (not shown) of the mounting surface 100a of the substrate 100, thus enabling a stable connection to the conductive part.

[0135] Next, the terminal portion 422 and protrusion 412 of the socket 4 are soldered to a conductive portion (not shown) on the mounting surface 100a of the substrate 100, and the foot portion 34 of the clamping member 6 is soldered to a conductive portion (not shown) on the through hole 100b of the substrate 100, thereby completing the installation of the electrical connector 11 with the substrate 100. At this time, as described above, the socket 4 is in a free state relative to the housing 5, so the coplanarity of the terminal portion 422 relative to the mounting surface 100a of the substrate 100 can be maintained in a good state without being affected by the housing 5.

[0136] The electrical connector 11, which is installed on the substrate 100 using the above mounting method, is as follows: Figure 18 As shown, the protrusion 26 of the housing 5 protrudes outward from the base plate 100. In this state, by providing the clamping member 6, the electrical connector 11, when viewed from above ( Figure 18 In the state shown, the portion overlapping with the substrate 100 has a center of gravity position. As a result, the electrical connector 11 can be mounted on the substrate 100 in a stable state.

[0137] Furthermore, by providing a limiting part 331 above the foot 34 of the conductive part soldered to the through hole 100b, when the electrical connector 11 is mounted on the mounting surface 100a of the substrate 100, the limiting part 331 can reliably limit the elastic deformation of the engaging part 22 to the left and right sides.

[0138] Thus, according to this embodiment, the housing 5 has a spring portion 51 and a movable portion 52 provided above the receiving portion 21 and capable of pressing the socket 4 held in the receiving portion 21 by the engaging portion 22 downward through elastic deformation. This not only achieves the effect of the first embodiment described above, but also stably mounts the socket 4 to the mounting surface 100a of the substrate 100.

[0139] It should be noted that in this embodiment, when the electrical connector 11 is installed on the mounting surface 100a, the movable part 52 is pressed downward by the suction nozzle 200. However, it is not limited to this, the movable part 52 can also be pressed downward by a clamp or other means other than the suction nozzle 200.

[0140] Furthermore, in this embodiment, a structure is adopted in which the outer side portion 36 is not provided in the clamping member 6, but it is not limited to this, and the outer side portion 36 may also be provided in the clamping member 6.

[0141] Furthermore, in this embodiment, the clamping member 6 is used to limit the elastic deformation of the engaging portion 22 in the direction that causes the socket 4 to detach from the receiving portion 21. However, it is not limited to this. Alternatively, a mounting member other than the clamping member 6 can be attached to the housing 5, and the mounting member can be used to limit the elastic deformation of the engaging portion 22 in the direction that causes the socket 4 to detach from the receiving portion 21.

[0142] (Third Implementation)

[0143] <Structure of Electrical Connectors>

[0144] The following is for reference Figures 20 to 22 The structure of the electrical connector 12 according to the third embodiment of the present invention will be described in detail.

[0145] It should be noted that, in Figures 20 to 22 In the middle, to and Figures 1 to 15 Parts with the same structure are labeled with the same reference numerals, and their descriptions are omitted.

[0146] The electrical connector 12 of this embodiment has a socket 4, a housing 7, a clamping member 8, and a sliding member 9.

[0147] The housing 7 is formed of an insulating material such as resin, and includes a front wall portion 19, a protruding wall portion 20, a receiving portion 21, a locking portion 22, a contact portion 23, a fitting portion 24, a through portion 25, a protruding portion 26, a rear wall portion 28, an inner top wall portion 29, an opening portion 30, a connecting hole 71, and a flat portion 72.

[0148] The receiving part 21 is recessed on the bottom surface, i.e. the lower surface, of the housing 7, and its rear end is connected to the outside.

[0149] When the housing 7 has been mounted on the mounting surface 100a of the substrate 100, the abutting part 23 abuts against the mounting surface 100a.

[0150] The insertion part 25 is a through hole that extends along the vertical direction around the receiving part 21, through which the clamping member 8 is inserted.

[0151] When the housing 7 has been mounted on the mounting surface 100a of the substrate 100, the protrusion 26 protrudes outward and forward from the substrate 100 (see reference). Figure 17 ).

[0152] The rear wall portion 28 is located at the rear end of the housing 7, and its center in the left-right direction is recessed forward.

[0153] The inner top wall portion 29 is located above the receiving portion 21 and is positioned opposite the socket 4 held in the receiving portion 21 in a spaced manner.

[0154] The connecting hole 71 extends upward from the receiving portion 21, with its upper end opening outward, and the connecting hole 71 holds the slider 9 so that it can move in the vertical direction.

[0155] The flat portion 72 is provided around the connecting hole 71 on the upper surface of the rear of the housing 7, and is flat along the front-back direction and the left-right direction.

[0156] The clamping member 8 is formed by bending a metal sheet after punching it using a stamping process. It is a mounting member that is attached to the housing 7 to fix the housing 7 to the base plate 100. The clamping member 8 is inserted into the insertion portion 25 of the housing 7 and is assembled to the housing 7. The clamping member 8 has a rear surface portion 32, an inner side portion 33, a foot portion 34, a front surface portion 35, a top portion 81, and a window portion 82.

[0157] The rear surface portion 32 is formed to bend downward from the rear end of the top portion 81, covering the rear wall portion 28.

[0158] The inner side portion 33 is formed to bend backward from the left and right ends of the front surface portion 35 and is provided on the left and right sides of the top surface portion 81, and is inserted into the insertion portion 25.

[0159] The foot 34 protrudes downward from the insertion part 25 and is located above the bottom surface of the housing 7.

[0160] The front surface portion 35 is formed to bend downward from the front end of the top surface portion 81 and insert into the insertion portion 25.

[0161] The top part 81 covers the flat part 72.

[0162] The window opening 82 is a through hole located approximately in the center of the top surface 81 and extending along the thickness direction, so that the upper end of the sliding member 9 held in the connecting hole 71 is exposed to the outside.

[0163] The slider 9 is cylindrical and is held in the connecting hole 71 in a manner that allows it to move freely in the vertical direction. The slider 9 can press the socket 4 downward by moving downward.

[0164] <Manufacturing Method of Electrical Connectors>

[0165] The following is for reference Figures 16 to 18 The manufacturing method of the electrical connector 12 according to the third embodiment of the present invention will be described in detail.

[0166] First, the housing 7 is formed using resin material and injection molding, etc., and the clamping part 8 is formed by stamping a metal sheet. In addition, the socket 4, manufactured using existing methods, is prepared.

[0167] Next, an insertion process is performed in which the slider 9 is inserted from below into the communicating hole 71 of the housing 7, and then the socket 4 is inserted from the front of the protruding wall portion 20 and from below into the receiving portion 21 of the housing 7. At this time, the socket 4 is inserted into the receiving portion 21 while the engaging portion 22 of the housing 7 is elastically deformed outward by the cover 43 of the socket 4. It should be noted that the subsequent manufacturing method is the same as the manufacturing method of the electrical connector 1, therefore its description is omitted.

[0168] With the electrical connector 12 in the completed state, the locking portion 22 is restricted from elastically deforming to the left and right by the limiting portion 331 of the inner side portion 33, thereby preventing the socket 4 from falling off the receiving portion 21 downwards before the electrical connector 12 is installed on the substrate 100.

[0169] <Installation Method of Electrical Connectors>

[0170] The following is for reference Figures 16 to 18 The installation method of the electrical connector 12 according to the third embodiment of the present invention will be described in detail.

[0171] The suction nozzle 200 of the mounting machine is used to suction the sliding member 9 of the electrical connector 12 manufactured by the above-described method, which protrudes from the window 82 of the clamping member 8, and the electrical connector 12 is transferred to the mounting surface 100a of the substrate 100. At this time, the terminal portion 422 of the socket 4 is located below the abutting portion 23 of the housing 7 by the engaging claw portion 221 of the engaging portion 22 engaging with the engaging portion 432 of the cover 43. Furthermore, the socket 4 is positioned opposite the inner top wall portion 29 of the housing 7 with a gap.

[0172] Next, the foot 34 of the clamping member 8 of the electrical connector 12 is inserted from above into the through hole 100b of the substrate 100.

[0173] By inserting the foot 34 through the through hole 100b, firstly, the terminal portion 422 of the contact 42 of the socket 4 and the protrusion 412 of the shield 41 abut against the mounting surface 100a, and then the abutting portion 23 of the housing 7 abuts against the mounting surface 100a.

[0174] Before the terminal portion 422 and the protrusion 412 abut against the mounting surface 100a, the vertical distance between the lower end of the abutting portion 23 and the upper end of the locking claw portion 221 is smaller than the vertical distance between the lower end of the engaged portion 432 of the socket 4 and the welding surface of the terminal portion 422. The welding surface of the terminal portion 422 and the lower end of the protrusion 412 are located below the lower end of the abutting portion 23. By abutting the terminal portion 422 and the protrusion 412 against the mounting surface 100a in this state, the engaged portion 432 moves upward relative to the locking claw portion 221, thereby moving away from the locking claw portion 221, and the socket 4 moves upward relative to the housing 7 within the receiving portion 21. Thus, the socket 4 becomes a free state unaffected by the housing 7.

[0175] Furthermore, by moving the socket 4 upward relative to the housing 7, the terminal portion 422 of the socket 4 is positioned approximately at the same location as the abutment portion 23 of the housing 7 in the vertical direction. Additionally, by moving the socket 4 upward relative to the housing 7, it is positioned opposite the inner top wall portion 29 of the housing 7, closer to it than before it was installed on the mounting surface 100a, and the sliding member 9 is pushed upward.

[0176] It should be noted that, in this invention, the soldering surface of the terminal portion 422 of the socket 4 is located below the lower end of the abutment portion 23 of the housing 7 before the electrical connector 12 is installed on the substrate 100. However, this is not a limitation; the soldering surface of the terminal portion 422 and the lower end of the abutment portion 23 may also be at the same height in the vertical direction. In this case, even if the locking claw portion 221 and the engaged portion 432 are not completely separated after the terminal portion 422 abuts against the substrate 100, the socket 4 will remain in a free state unaffected by the housing 7, as long as the weight of the socket 4 is not exerted on the locking claw portion 221 via the engaged portion 432.

[0177] Furthermore, the limiting portion 331 of the clamping member 8 allows the engaging portion 22 to elastically deform to the left and right outside within a range that will not cause the socket 4 to fall off the receiving portion 21 downwards. Therefore, the terminal portion 422 can be reliably abutted against the welding position of the mounting surface 100a while the position of the terminal portion 422 is adjusted in the left and right direction relative to the welding position of the mounting surface 100a.

[0178] Next, the slider 9 is pressed downward by the suction nozzle 200, thereby moving downward within the connecting hole 71 to press 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 substrate 100, thus enabling a stable connection to the conductive portion.

[0179] Next, the terminal portion 422 and protrusion 412 of the socket 4 are soldered to a conductive portion (not shown) on the mounting surface 100a of the substrate 100, and the foot portion 34 of the clamping member 8 is soldered to a conductive portion (not shown) on the through hole 100b of the substrate 100, thereby completing the installation of the electrical connector 12 with the substrate 100. At this time, as described above, the socket 4 is in a free state relative to the housing 7, so the coplanarity of the terminal portion 422 relative to the mounting surface 100a of the substrate 100 can be maintained in a good state without being affected by the housing 7.

[0180] The electrical connector 12, which is installed on the substrate 100 using the above mounting method, is as follows: Figure 21 As shown, the protrusion 26 of the housing 7 protrudes outward from the base plate 100. In this state, by providing the clamping member 8, the electrical connector 12, when viewed from above ( Figure 21 In the state shown, the portion overlapping with the substrate 100 has a center of gravity position. As a result, the electrical connector 12 can be mounted on the substrate 100 in a stable state.

[0181] Furthermore, by providing a limiting part 331 above the foot 34 of the conductive part soldered to the through hole 100b, when the electrical connector 12 is mounted on the mounting surface 100a of the substrate 100, the limiting part 331 can reliably limit the elastic deformation of the engaging part 22 to the left and right sides.

[0182] Thus, according to this embodiment, the housing 7 includes a communicating hole 71 extending upward from the receiving portion 21, with its upper end opening outward. The communicating hole 71 holds the slider 9 so that it can move in the vertical direction. The slider 9 can move downward within the communicating hole 71 to press the socket 4 held in the receiving portion 21 by the engaging portion 22 downward. This not only achieves the effect of the first embodiment described above, but also stably mounts the socket 4 to the mounting surface 100a of the substrate 100.

[0183] It should be noted that in this embodiment, when the electrical connector 12 is installed on the mounting surface 100a, the sliding member 9 is pressed downward by the suction nozzle 200. However, it is not limited to this, the sliding member 9 can also be pressed downward by a clamp or other means other than the suction nozzle 200.

[0184] Furthermore, in this embodiment, the clamping member 8 is used to limit the elastic deformation of the engaging portion 22 in the direction that causes the socket 4 to detach from the receiving portion 21. However, it is not limited to this. Alternatively, a mounting member other than the clamping member 8 may be attached to the housing 7, and the engaging portion 22 may be limited in the direction that causes the socket 4 to detach from the receiving portion 21 by the mounting member.

[0185] The types, configurations, and numbers of components of the present invention are not limited to the above-described embodiments. Of course, appropriate changes can be made within the scope of the invention, such as appropriately replacing the components with components that can achieve the same effect.

[0186] Specifically, in the first to third embodiments described above, the socket 4 is held in the receiving portion 21, but it is not limited to this, and a connector with a different structure from the socket 4 may also be held in the receiving portion 21.

[0187] Furthermore, in the first to third embodiments described above, the socket 4 held in the receiving portion 21 can move in the upward and left-right directions, but is not limited to this. It is also possible that the socket 4 held in the receiving portion 21 can move not only in the upward and left-right directions, but also in the front-back direction. In this case, the socket 4 held in the receiving portion 21 can self-align inside the housing 2, housing 5, or housing 7.

[0188] Furthermore, in the first to third embodiments described above, the limiting part 311 is provided above the foot 34, but it is not limited thereto. The limiting part 311 can be provided near the foot 34 other than above the foot 34, such as between a pair of feet 34. In this case, the limiting part 311 can also reliably limit the elastic deformation of the engaging part 22 to the left and right sides.

Claims

1. An electrical connector comprising a housing and a socket mounted on a mounting surface of a substrate, characterized in that, The housing includes: a receiving portion disposed on a bottom surface facing the mounting surface, which receives the socket in a state in which the socket is exposed to the outside; and a retaining portion that retains the socket in the receiving portion; A contact portion abuts against the mounting surface; an inner top wall portion faces the socket above the socket held in the receiving portion by the retaining portion; and a pressing portion protrudes downward from the inner top wall portion, and has a gap between the pressing portion and the socket held in the receiving portion by the retaining portion. The socket has a terminal portion soldered to the mounting surface. When the socket is held in the receiving portion by the retaining portion, the terminal portion is located at the same height as the abutting portion or below the abutting portion, and the socket can move upward. When the abutting portion has abutted against the mounting surface, the socket is pressed against the mounting surface by the pressing portion.

2. The electrical connector according to claim 1, characterized in that, The socket has a protrusion that protrudes downward between the terminal portion and the abutting portion and abuts against the mounting surface. The pressing part is located between the terminal part and the protrusion.

3. The electrical connector according to claim 1 or 2, characterized in that, The housing has a protrusion that protrudes from the substrate when the electrical connector is mounted on the mounting surface. When the electrical connector is installed on the mounting surface, when viewed from above, the electrical connector has a center of gravity position in the portion that overlaps with the substrate.

4. A method for manufacturing an electrical connector, comprising a housing and a socket having a mounting surface mounted on a substrate, characterized in that, have: The insertion process involves inserting the socket into a receiving portion located on the bottom surface of the housing, facing the mounting surface; and In the holding process, the socket, which was inserted into the receiving portion during the insertion process, is held in the receiving portion in a state of being exposed to the outside through the holding portion of the housing. This causes the terminal portion of the socket soldered to the mounting surface to be located at the same height as or below the abutment portion of the housing that abuts the mounting surface, and allows the socket to move upwards. During the holding process, when the abutting part has abutted against the mounting surface, the pressing part can press the socket toward the mounting surface, wherein the pressing part protrudes downward from the inner top wall of the housing and has a gap between the pressing part and the socket, and the inner top wall is above the socket held in the receiving part by the holding part and opposite the socket.

5. A method for mounting an electrical connector, comprising mounting an electrical connector having a housing and a socket onto a mounting surface of a substrate, characterized in that, The socket is held in an exposed state in a receiving portion on the bottom surface of the housing opposite the mounting surface by the retaining portion of the housing. This causes the terminal portion of the socket soldered to the mounting surface to be located at the same height as or below the abutting portion of the housing that abuts against the mounting surface, and allows the socket to move upward. The inner top wall of the housing is above the socket held in the receiving portion by the retaining portion and faces the socket. A pressing portion protruding downward from the inner top wall has a gap between it and the socket. In this state, when the abutting portion abuts against the mounting surface, the pressing portion presses the socket against the mounting surface, and the terminal portion is soldered to the mounting surface.
