Description

connector

The present invention relates to a connector capable of connecting circuit boards and taking measures against noise.

Electronic devices and electrical devices such as desktop PCs (personal computers), notebook PCs, and tablet PCs generally have a circuit board on which electronic components are mounted and another circuit board on which other electronic components are mounted. Built-in.

The connector of patent document 1 is a connector for connecting these two circuit boards, and a receptacle connector mounted on a circuit board (first circuit board, rigid board) and another circuit board (second circuit board). A plug connector mounted on a rigid board).
The receptacle connector includes a receptacle insulator and a plurality of receptacle contacts. The receptacle insulator includes an annular outer peripheral wall and a fitting recess formed inside the outer peripheral wall. The plurality of receptacle contacts are supported by the receptacle insulator in a state where they are aligned in the longitudinal direction of the receptacle connector. Each receptacle contact includes a tail piece mounted on a circuit pattern formed on the mounting surface of the first circuit board, and a contact piece located in the fitting recess of the receptacle insulator.

On the other hand, the plug connector includes a plug insulator and a plurality of plug contacts. The plug insulator includes an annular fitting convex portion that can be fitted into the fitting concave portion. Each plug contact includes a tail piece mounted on the circuit pattern on the mounting surface of the second circuit board, and a contact piece integrated with the fitting convex portion of the plug insulator.

When the mating convex portion of the plug connector is fitted (connected) to the mating concave portion of the receptacle connector, the contact piece of each plug contact comes into contact with the contact piece of each receptacle contact, and the first circuit board and the second Two circuit boards are parallel. The electronic component mounted on the first circuit board and the electronic component mounted on the second circuit board are electrically connected to each other.

In recent electronic devices and electrical devices, an increase in information volume and a speed-up of communication speed are remarkably advanced, and thus noise countermeasures in the devices are an important issue. For this reason, there is a strong demand for improvement in noise resistance and suppression of noise emitted to the periphery of the connector.
Therefore, in the receptacle connector of Patent Document 1, a metal conductive member (shield member) covering the outer peripheral surface is attached to the outer peripheral surface of the receptacle insulator.
This conductive member is electrically connected to the ground pattern formed on the first circuit board. Therefore, it is possible to reduce external noise from entering into the receptacle contacts (and plug contacts) of the receptacle connector and leakage of noise from the receptacle contacts (and plug contacts) to the outside.

JP 2013-140755 A

In recent years, as the thickness of electronic devices and electrical devices has been reduced, the thickness of connectors has been reduced, so that the distance between the opposing surfaces of the first circuit board and the second circuit board has become shorter. Therefore, the distance from the conductive member to the first circuit board and the second circuit board and the distance from the conductive member to the tail piece of the receptacle contact are shortened.
Therefore, if the tail piece of the receptacle contact and the mounting surface of the first circuit board are soldered, or if foreign matter such as fine dust adheres to the mounting surface or tail piece, There is a possibility that (electrical) short circuit may occur between the conductive member and the first circuit board and the second circuit board (circuit pattern thereof) and between the conductive member and the tail piece of the receptacle contact. .

Further, before connecting the receptacle connector and the plug connector, the metal member on the plug connector side (for example, a fixing bracket for fixing the plug insulator to the second circuit board) is brought into contact with the conductive member, so that In some cases, static electricity flowing from the conductive member to the plug connector may be intentionally passed from the conductive member to the first circuit board (ground pattern) side. In this way, it is possible to prevent static electricity from flowing into the receptacle contact and the circuit pattern of the first circuit board, and electronic components connected to the first circuit board (and the second circuit board) from being electrostatically damaged by static electricity. .
However, when the distance from the conductive member to the tail piece of the receptacle contact is short, a discharge occurs between the conductive member and the tail piece of the receptacle contact, and the static electricity flows to the receptacle contact and the circuit pattern of the first circuit board. There is a fear.

In recent years, when the receptacle connector and the plug connector are connected, the distance between the first circuit board and the second circuit board (the fitting height of the connector) is 1 mm or less (the distance between the conductive member and the tail piece is also The possibility of the above problems ("short circuit" and "electrostatic breakdown by discharge") is high.

The present invention effectively prevents a short circuit or a discharge from occurring between the conductive member and the circuit board or contact when the first connector and the second connector are connected, even when the entire connector is low-profile. A connector that can be reduced is provided.

A connector of the present invention includes a first insulator having an annular outer peripheral wall and a fitting recess formed inside the outer peripheral wall, a first contact piece located in the fitting recess, and a circuit of a first circuit board A plurality of first contacts supported by the first insulator, and a first connector having a conductive member supported by the first insulator; A second insulator having a ring-shaped fitting projection that can be mated, and a circuit pattern of a second circuit board supported by the second insulator, and the fitting projection can be fitted into the fitting recess. A second connector comprising a plurality of second contacts comprising a second contact piece that contacts the first contact piece when the first contact is provided on the first circuit board. When mounted on the circuit pattern and the second contact is mounted on the circuit pattern of the second circuit board, the conductive member is located between the first circuit board and the second circuit board, The outer peripheral wall has a conductive member shielding part located between the first circuit board and the tail piece and the conductive member, and / or between the second circuit board and the conductive member. It is characterized by that.

The conductive member shielding part is located between the first circuit board and the tail piece and the conductive member, and between the second circuit board and the conductive member. You may have a 2nd shielding part.

The conductive member may include an outer peripheral shielding portion that covers the outer peripheral surface of the outer peripheral wall.

After the tail piece of the first contact of the first connector is mounted on the first circuit board (the circuit pattern thereof) and the second contact of the second connector is mounted on the second circuit board (the circuit pattern thereof), the second insulator is mounted. When the fitting convex portion is fitted into the fitting concave portion of the first insulator, the first contact and the second contact are electrically connected to each other.
When the connector has a low-profile structure, the distance from the conductive member to the first circuit board and the tail piece and the distance from the conductive member to the second circuit board (at least one) are shortened.
However, the outer peripheral wall of the first insulator includes a conductive member shielding portion located between the first circuit board and the tail piece and the conductive member and / or between the second circuit board and the conductive member. Therefore, when the first connector and the second connector are connected, it is possible to effectively reduce the possibility of a short circuit or discharge occurring between the first circuit board, the second circuit board, the tail piece, and the conductive member. .

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In the following description, front and rear, left and right, and up and down directions are based on the arrow direction in the figure.
The connector 10 of this embodiment includes a plug connector 15 and a receptacle connector 35.

First, the detailed structure of the plug connector 15 (second connector) will be described with reference mainly to FIGS.
The plug connector 15 includes a plug insulator 16 as a large component, a large number of plug contacts 25 (second contacts), and two fixing brackets 28.
The plug insulator 16 is a plate-like member extending in the left-right direction in which an insulating and heat-resistant synthetic resin material is injection-molded. The plug insulator 16 includes a ceiling plate portion 17 constituting an upper end portion, and a fitting convex portion 18 formed of an annular wall projecting downward from the entire peripheral portion of the lower surface of the ceiling plate portion 17. A space formed by the ceiling plate portion 17 and the fitting convex portion 18 constitutes an engaging concave portion 19. A large number of contact mounting grooves 21 having a substantially U-shaped cross-section straddling the front and rear surfaces and the lower surface are arranged in the front wall and the rear wall of the fitting projection 18 in the left-right direction (see FIG. 7). Further, the fitting mounting recesses 22 that are recessed downward are respectively provided on the upper surfaces of the left and right walls of the fitting protrusion 18 (see FIG. 9).

Each plug contact 25 is formed by stamping a thin plate of a copper alloy (for example, phosphor bronze, beryllium copper, titanium copper, corson copper) having spring elasticity so as to have the illustrated shape, and gold, tin, or the like on the surface. Has been plated. The plug contact 25 includes a contact piece 26 (second contact piece) extending in the vertical direction constituting an inner portion of the main body portion having a substantially U-shaped cross section, and a tail piece 27 extending substantially horizontally from the upper end of the outer portion of the main body portion. ,have.
Each plug contact 25 is fixed to the plug insulator 16 by fitting (press-fitting) into each contact mounting groove 21 from below (see FIGS. 1, 2, 7, etc.).
Each fixing bracket 28 is formed by stamping a metal plate into the illustrated shape, and a pair of substantially horizontal tail pieces 29 is formed at the upper end portion thereof.
Each fixing bracket 28 is press-fitted in a fixed state with respect to each bracket mounting recess 22 from above, and each tail piece 29 protrudes upward from the upper surface of the plug insulator 16.
The plug connector 15 having the above structure is mounted on a mounting surface formed on one surface of a circuit board 31 (rigid board; second circuit board; see FIGS. 1 and 7 to 9). Specifically, the tail piece 27 of each plug contact 25 is soldered to a circuit pattern (not shown) formed on the mounting surface (lower surface) of the circuit board 31 and the tail piece 29 of each fixing bracket 28 is soldered. Are soldered to a ground pattern (not shown) formed on the mounting surface (so-called straight (ST) connection). Electronic components other than the plug connector 15 (for example, high-function modules, semiconductors, large-capacity memories, etc.) are mounted on the mounting surface of the circuit board 31.

Next, the detailed structure of the receptacle connector 35 (first connector) will be described with reference mainly to FIGS.
The receptacle connector 35 includes a receptacle insulator 36 (first insulator), a large number of receptacle contacts 50 (first contacts), and two shells 55 (conductive members) as large components.
The receptacle insulator 36 is a member extending in the left-right direction obtained by injection molding (specifically, insert molding as will be described later) of an insulating and heat-resistant synthetic resin material. The receptacle insulator 36 includes a bottom plate portion 37 constituting a lower portion, an outer peripheral wall 38 formed of an annular wall protruding upward from the entire peripheral portion of the upper surface of the bottom plate portion 37, and an engaging protrusion protruding upward from the upper surface of the bottom plate portion 37. Part 39. The engaging convex part 39 spaced apart from the outer peripheral wall 38 to the inner peripheral side extends linearly in the left-right direction. A space formed between the outer peripheral wall 38 and the engaging convex portion 39 constitutes an annular fitting concave portion 40.
The portions of the outer peripheral wall 38 excluding the front and rear left and right ends are constituted by a front wall 38a and a rear wall 38b. As shown in the drawing, the front surface of the front wall 38a is positioned one step behind the parts located on the left and right sides of the front wall 38a, and the rear surface of the rear wall 38b is compared with the parts located on the left and right sides of the rear wall 38b. Located one step ahead. A large number of contact mounting grooves 42 extending in the vertical direction are formed in the rear surface of the front wall 38a and the front surface of the rear wall 38b in the horizontal direction (the same number as the plug contacts 25). Further, in a portion straddling the bottom surface of the bottom plate portion 37 positioned immediately before the engaging convex portion 39 and the front surface of the engaging convex portion 39, a deformation allowing groove 43 continuous with the contact mounting groove 42 of the corresponding front wall 38a is recessed. Similarly, in a portion straddling the bottom surface of the bottom plate portion 37 located immediately after the engaging convex portion 39 and the rear surface of the engaging convex portion 39, the contact mounting groove 42 of the corresponding rear wall 38b is continuous. The deformation allowable groove 43 is recessed (see FIGS. 5 and 7).

Each receptacle contact 50 is formed by the same material and the same procedure as the plug contact 25, and includes a substantially horizontal tail piece 51, a fixed piece 52 extending upward from the inner end of the tail piece 51, and the fixed piece 52. A substantially S-shaped elastic contact piece 53 (first contact piece) continuous to the upper end portion.
Each receptacle contact 50 is inserted into each contact mounting groove 42 and each deformation allowance groove 43 from below the receptacle insulator 36, and a fixing piece 52 is press-fitted (fixed) into the contact mounting groove 42. When the receptacle contact 50 (fixed piece 52) is fixed to the receptacle insulator 36 (contact mounting groove 42), the elastic contact piece 53 is separated from the inner surface of the deformation allowable groove 43, so that the elastic contact piece 53 is elastic in the deformation allowable groove 43. It can be deformed (see FIG. 7). Further, the tail piece 51 of each receptacle contact 50 is located below the lower surface of the bottom plate portion 37 (see FIGS. 1 to 3 and the like).

The pair of front and rear shells 55 are symmetrical with each other. Each shell 55 is formed by press-molding a metal plate (conductive material), and includes a flat plate-shaped outer peripheral shielding portion 56 that extends in the left-right direction and has the same length as the front wall 38a and the rear wall 38b. Yes. Fixing portions 57 that are substantially L-shaped in plan view and wider in the vertical direction than the outer shielding portion 56 are provided at both left and right ends of the outer shielding portion 56. A tail piece 58 positioned below the lower surface of the outer peripheral side shielding portion 56 is formed at the lower end portion of each fixing portion 57.
Portions of the fixing portion 57 of the front and rear shells 55 other than the outer surface of the outer peripheral side shielding portion 56 are embedded in the receptacle insulator 36. That is, the receptacle insulator 36 and the respective shells 55 are integrated by insert-molding the receptacle insulator 36 into the shell 55. On the other hand, the outer peripheral side shielding portions 56 of the front and rear shells 55 are placed on the front surface of the front wall 38a and the rear surface of the rear wall 38b (in contact with the front wall 38a and the rear wall 38b).
When insert-molding (injection molding) the receptacle insulator 36, an upper shielding portion 38a1 (conductive member shielding portion) (second shielding portion) projecting forward is formed on the upper and lower edges of the front wall 38a. A lower shielding part 38a2 (conductive member shielding part) (first shielding part) is formed over the entire length of the front wall 38a. Similarly, when the receptacle insulator 36 is insert-molded (injection-molded), an upper shielding portion 38b1 (conductive member shielding portion) (second shielding member) protruding rearward is formed on the upper and lower edges of the rear surface of the rear wall 38b. Part) and a lower shielding part 38b2 (conductive member shielding part) (first shielding part) are formed over the entire length of the rear wall 38b. As shown in FIGS. 3, 7, and 8, the upper shielding portion 38 a 1 and the lower shielding portion 38 a 2 are respectively positioned (contacted) on the upper and lower surfaces of the outer circumferential side shielding portion 56 of the front shell 55, and the rear shell The upper shielding part 38b1 and the lower shielding part 38b2 are respectively positioned (contacted) on the upper and lower surfaces of the outer peripheral side shielding part 56. Further, the lower shielding portion 38a2 is located immediately above the tail piece 51 of the front receptacle contact 50, and the lower shielding portion 38b2 is located immediately above the tail piece 51 of the rear receptacle contact 50.

The receptacle connector 35 having the above-described structure corresponds to a circuit pattern (not shown) formed on the mounting surface of the circuit board 60 (rigid board, first circuit board) which is a plate material parallel to (including substantially parallel to) the circuit board 31. Then, the tail piece 51 of each receptacle contact 50 is soldered, and the tail piece 58 is soldered to the ground pattern formed on the mounting surface, thereby fixing (mounting) to the circuit board 60 (see FIG. 7—See FIG. 9) (so-called straight (ST) connection). Electronic components (for example, CPU, controller, memory, etc.) different from the receptacle connector 35 are mounted on the mounting surface of the circuit board 60.

The plug connector 15 and the receptacle connector 35 configured as described above are connected in the following manner.
First, as shown in FIGS. 1 and 2, the plug connector 15 and the receptacle connector 35 are opposed to each other in the vertical direction while matching the front and rear positions and the left and right positions. Then, the plug connector 15 is moved downward to fit the fitting convex portion 18 into the fitting concave portion 40, and the engaging concave portion 19 is fitted into the engaging convex portion 39 (see FIGS. 7 to 9). Then, the contact piece 26 of each plug contact 25 comes into contact with the elastic contact piece 53 while elastically deforming the corresponding elastic contact piece 53 of the receptacle contact 50, so that the circuit board 31 is interposed via the plug contact 25 and the receptacle contact 50. And the circuit board 60 can be electrically connected.

Further, the outer peripheral side shielding portion 56 and the fixing portion 57 of the front and rear shells 55 are positioned on the outer peripheral side of each plug contact 25 and each receptacle contact 50. For this reason, the front and rear shells 55 can effectively prevent external noise from entering the plug contacts 25 and the receptacle contacts 50 and the leakage of noise from the plug contacts 25 and the receptacle contacts 50 to the outside (the shell 55 is effective). Exhibits the shielding function). Accordingly, a large amount of electronic components (for example, high-function modules, semiconductors, large-capacity memories, etc.) mounted on the circuit board 31 and the electronic components (for example, CPU, controller, memory, etc.) mounted on the circuit board 60 (large amount). B) High-speed communication of information becomes possible.
Further, since the upper shielding portions 38a1 and 38b1 are formed in the receptacle insulator 36, the upper surface of the outer peripheral shielding portion 56 is not exposed. For this reason, when the plug connector 15 is fitted to the receptacle connector 35, the plug contact 25 and the fitting convex portion 18 do not come into contact with the outer peripheral side shielding portion 56. There is no fear of being damaged by the side shielding part 56 or being caught by the outer side shielding part 56. Therefore, the connector 10 can smoothly fit and insert the plug connector 15 and the receptacle connector 35 while exhibiting the shielding function by the shell 55.

Since the connector 10 (the plug connector 15 and the receptacle connector 35) of this embodiment has a low-profile structure, when the plug connector 15 and the receptacle connector 35 are connected, the distance between the opposing surfaces of the circuit board 31 and the circuit board 60 (vertical distance). The distance from the outer peripheral side shielding portion 56 of the shell 55 to the lower surface of the circuit board 31 and the distance from the outer peripheral side shielding portion 56 of the shell 55 to the upper surface of the circuit board 60 and the upper surface of the tail piece 51 of the receptacle contact 50 are reduced. Both become shorter. Specifically, when the distance between the opposing surfaces of the circuit boards 31 and 60 (fitting height of the connector 10) is 0.6 mm and the thickness (vertical dimension) of the outer peripheral shielding portion 56 is 0.28 mm, the shell The distance from the outer peripheral side shielding portion 56 of 55 to the lower surface of the circuit board 31 is 0.16 mm, the distance from the outer peripheral side shielding portion 56 of the shell 55 to the upper surface of the circuit board 60 is 0.16 mm, and the outer peripheral side shielding portion of the shell 55 The distance between 56 and the tail piece 51 of the receptacle contact 50 is 0.1 mm, and the thicknesses of the lower shielding part 38a2 and the lower shielding part 38b2 are set to 0.05 mm.
However, the receptacle insulator 36 is located between the circuit board 31 and the outer shield part 56 and between the upper shield part 38a1 and the upper shield part 38b1, and between the circuit board 60 and the tail piece 51 and the outer shield part 56. The lower shielding part 38a2 and the lower shielding part 38b2 are provided. For this reason, the outer peripheral side shielding part 56, the circuit board 31 and the circuit board 60 (of the circuit board 60) are connected via the solder applied to the tail piece 51, the mounting surface of the

circuit boards

31 and 60, and foreign matters such as fine dust attached to the tail piece 51. (Electrical) short circuit between the outer peripheral side shielding portion 56 and the tail piece 51 of the receptacle contact 50 is hardly caused.

Further, when the plug connector 15 and the receptacle connector 35 are connected, the fixing metal 28 of the plug connector 15 is brought into contact with the outer peripheral side shielding portion 56 so that static electricity flowing from the operator's hand or the like to the plug connector 15 is shielded on the outer peripheral side. In some cases, the portion 56 is intentionally flowed to the ground pattern side of the circuit board 60.
As described above, in this embodiment, the distance from the outer peripheral side shielding portion 56 of the shell 55 to the tail piece 51 of the receptacle contact 50 is short. However, since the receptacle insulator 36 includes the lower shielding part 38a2 and the lower shielding part 38b2 positioned between the tail piece 51 and the outer shielding part 56, the static electricity that has flowed from the plug connector 15 to the outer shielding part 56. Is less likely to be discharged from the outer shielding part 56 to the tail piece 51.
For this reason, static electricity transmitted to the outer peripheral side shielding portion 56 flows into the receptacle contact 50 (and the circuit pattern of the circuit board 60) due to discharge, and the electronic components and the like connected to the circuit board 60 (and the circuit board 31) are electrostatically damaged. The fear is small.

As mentioned above, although this invention was demonstrated based on said each embodiment, this invention is not limited to the said embodiment, It can implement, giving various deformation | transformation.
For example, the upper shielding portions 38a1 and 38b1 are omitted from the receptacle insulator 36 as in the first modification shown in FIG. 10A, or the receptacle insulator 36 is used as in the second modification shown in FIG. The lower shielding portions 38a2 and 38b2 may be omitted.
Further, as in the third modified example shown in FIG. 11, the shell 55 ′ may be constituted by two members (or three or more members) of a split shell member 55A and a split shell member 55B separated in the left-right direction. Further, although not shown, the shell 55 may be composed of a plurality of members separated in the vertical direction.
Further, one of the front and rear shells 55 (55 ′) may be omitted.
Further, the outer peripheral side shielding portion 56 may be embedded in the receptacle insulator 36.

Further, a shell (conductive member) is provided on the plug insulator 16 (first insulator) of the plug connector 15 (first connector), and a shell is provided on the receptacle insulator 36 (second insulator) of the receptacle connector 35 (second connector). (In this modification, the circuit board 31 is the “first circuit board”, the circuit board 60 is the “second circuit board”, the upper shielding part 38a1 is the “first shielding part”, and the lower shielding part 38a2 is not provided. "Second shielding part"). In this case, the plug insulator 16 is provided with an outer peripheral wall positioned on the outer peripheral side of the fitting convex portion 18, and the front and rear width (between the front surface and the rear surface) of the outer peripheral wall is made wider than the receptacle insulator 36. The outer peripheral wall 38 of the receptacle insulator 36 (corresponding to the “fitting convex portion” in the claims) is fitted into the fitting concave portion formed between the fitting convex portion 18 and the outer peripheral wall, and The shell provided on the plug insulator 16 is preferably positioned on the outer peripheral side of each plug contact 25 (first contact) and each receptacle contact 50 (second contact). That is, in the fitting state of the plug connector 15 and the receptacle connector 35 (the contact piece 26 that is the “first contact piece” contacts the elastic contact piece 53 that is the “second contact piece”), the plug contact 25 and the receptacle contact 50. It is important that the shell is surrounded from the outer peripheral side (the plug contact 25 and the receptacle contact 50 are positioned inside the shell).
Further, the base material of the shell may be made of resin, and the surface of the base material (resin) may be plated or coated with a conductive material.
One of the plug connector 15 and the receptacle connector 35 may be connected to the corresponding circuit board in a so-called right angle (RA) manner. In this case, a shell is positioned on the outer peripheral side of the other of the plug connector 15 and the receptacle connector 35 (connected to the corresponding circuit board in a straight (ST) manner), and this shell and the circuit on the other connector side are located. The board is brought close to the thickness direction of the circuit board.
Further, a first circuit board and a second circuit board (for example, FPC (flexible printed circuit board)) other than the rigid board may be connected to the plug connector 15 or the receptacle connector 35.

The connector of the present invention has the effect of causing a short circuit or a discharge between the conductive member and the circuit board or contact when the first connector and the second connector are connected even when the entire connector is low-profile. Can be reduced.
