Description

Technical Field

[0001] The present invention relates to an electrical connector, particularly an electrical connector having a sequence structure in which each contact is connected to a contact of a mating connector in order with a time difference when mating with the mating connector.

Background Art

[0002] In recent years, batteries are built into miniaturized portable electronic devices such as notebook computers, tablet computers, digital cameras, mobile phones, etc. In order to connect this battery power supply to a circuit board mounted on the above-mentioned electronic device, an extremely small so-called chip size package type wire-to-board connector is used.

[0003] For example, Patent Document 1 below discloses a base connector provided with a ground contact, a power supply contact, and a plurality of signal contacts arranged in parallel between these ground contacts and power supply contacts in a rectangular parallelepiped housing.

Summary of the Invention

Problems to be Solved by the Invention

[0005] As described above, in the base connector of Patent Document 1, the ground contact and the power contact have substantially the same shape, and their lengths in the mating direction are also substantially the same. Therefore, since the effective length of the ground contact and the power contact that contacts the ground contact and power contact of the mating connector are the same, the timing at which conductivity begins to occur to the ground contact and power contact of the mating connector is the same.

[0006] Here, there is a market demand for a so-called sequence structure in which the ground contact makes contact with the ground contact of the mating connector before the power contacts make contact with each other, and then, after a time delay, the power contacts make contact with the power contacts of the mating connector.

[0007] However, in the case of wire-to-board connectors, if the mating length of the ground contact is made longer than that of the power contact to satisfy the above requirement, the tip of the ground contact will interfere with the core wire crimping portion of the ground contact of the mating connector.

[0008] Therefore, in order to increase the length of the ground contact in the mating direction and avoid interference with the core wire crimping portion of the mating connector's ground contact, it becomes necessary to increase the length of the mating connector's ground contact. Alternatively, it may be necessary to increase the vertical dimension perpendicular to the mating direction of the mating connector so that the core wire crimping portion does not interfere with the ground contact. However, such measures have the problem of increasing the overall size of the connector.

[0009] Therefore, the object of the present invention is to provide an electrical connector in which, in a wire-to-board connector, the ground contact can make contact with the contacts of the mating connector before the power contact, without changing the overall size of the connector. [Means for solving the problem]

[0010] To solve the above problems, one aspect of the present invention is: It has a ground contact and a power contact, The length of the ground contact in the mating direction is longer than the length of the power contact in the mating direction. The aforementioned electrical connector has a shape in which the ground contact has a sloping shape in which the height in the vertical direction perpendicular to the mating direction gradually increases from the tip portion in the mating direction toward the opposite side.

[0011] Furthermore, in one embodiment of the present invention, the length of the ground contact in the mating direction is such that the tip portion of the ground contact extends beyond the tip portion in the mating direction of the core wire crimping portion of the ground contact of the mating connector when mated with the mating connector.

[0012] Furthermore, in one embodiment of the present invention, the power supply contact does not have an inclined shape.

[0013] Furthermore, in one embodiment of the present invention, the electrical connector further comprises a signal contact, wherein the length of the ground contact in the mating direction is longer than the length of the signal contact in the mating direction.

[0014] Furthermore, in one embodiment of the present invention, the length of the signal contact in the mating direction is shorter than that of the power contact.

[0015] Furthermore, in one embodiment of the present invention, a housing is provided which houses the ground contact, the power contact, and the signal contact inside. The housing has a mating end that abuts against the housing of the mating connector, the tip portion of the ground contact in the mating direction extends to the vicinity of the mating end, and the tip portion of the power contact in the mating direction is located at a predetermined distance from the mating end on the opposite side of the mating side in the mating direction. [Effects of the Invention]

[0016] According to one aspect of the present invention, in a wire-to-board connector, an electrical connector can be provided in which the ground contact can contact the contact of the mating connector before the power contact without changing the overall size of the connector.

[0017] Also, according to one aspect of the present invention, when the length of the ground contact in the fitting direction does not interfere with the core wire crimping portion of the ground contact of the mating connector during fitting with the mating connector, the ground contact can be made to contact the ground contact of the mating connector earlier.

[0018] Also, according to one aspect of the present invention, the ground contact can contact the contact of the mating connector before the power contact and the signal contact.

[0019] Also, according to one aspect of the present invention, when fitting with the mating connector, contact with the contacts of the mating connector can be started in the order of the ground contact, the power contact, and the signal contact.

[0020] Also, according to one aspect of the present invention, when fitting with the mating connector, the start of conduction between the signal contact and the corresponding signal contact of the mating connector can be delayed compared to the start of conduction between the power contacts.

[0021] Also, according to one aspect of the present invention, when the fitting between the housing and the housing of the mating connector is started, it becomes possible to start contact between the ground contact extending to the vicinity of the fitting end of the housing and the ground contact of the mating connector.

MODE FOR CARRYING OUT THE INVENTION

[0023] The electrical connector 10 of the embodiment will be described with reference to the drawings. The embodiment described below is an example of the electrical connector of the present invention, but the present invention is not limited thereto. The present invention should be equally applicable to electrical connectors of other forms described in the claims.

[0024] As shown in Figure 1, the electrical connector 10 includes a base connector 20 and a socket connector 30. The base connector 20 is surface-mounted on a printed circuit board 40. Electrical wires 50 are connected to the socket connector 30. In this embodiment, an example is described in which the base connector 20 incorporates so-called male type contacts, while the socket connector 30 incorporates so-called female type contacts.

[0025] As shown in Figure 2, the base connector 20 comprises a rectangular base housing 202, a male ground terminal 204, a male power terminal 206, and a male signal terminal 208. The male ground terminal 204, the male power terminal 206, and the male signal terminal 208 are arranged and supported in the base housing 202 parallel to the width direction.

[0026] The base housing 202 has a rectangular parallelepiped shape and comprises an upper plate 210, a bottom plate 212, side plates 214 and 216, a rear plate 218, and a mating end 220 that abuts against the socket housing 302 of the mating connector, the socket connector 30. The mating end 220 opens forward in the mating direction, and a mating opening 222 is formed extending from this opening toward the rear in the mating direction into which the header portion 310, which is the mating projection of the socket connector 30, is inserted.

[0027] In this description of the embodiment, the direction in which the base connector 20 and the socket connector 30 are mated together will be referred to as the mating direction. The direction perpendicular to this mating direction, in which the male ground terminal 204, the male power terminal 206, and the male signal terminal 208 are arranged in approximately a straight line, will be referred to as the width direction, and the direction perpendicular to both the mating direction and the width direction will be referred to as the up and down direction. Furthermore, within the mating direction, the side of the base connector 20 that mats with the socket connector 30 will be referred to as the mating direction front, or simply front, and the opposite side will be referred to as the mating direction rear, or simply rear.

[0028] As shown in Figure 3(A), the male ground terminal 204 is made of a conductive material and includes a male ground contact blade 224 and a first plate 226 arranged parallel to each other. The rear upper ends of the male ground contact blade 224 and the first plate 226 are connected to each other by a connecting portion 228, resulting in the male ground terminal 204 having an overall U-shape.

[0029] The male ground contact blade 224 is a flat plate-shaped body that is particularly elongated in the front-to-back direction within a virtual plane extending in the vertical and front-to-back directions, and as a ground contact, it connects to the contact portion 324a of the female ground terminal 304 of the socket connector 30 when mated. The length of this male ground contact blade 224 in the mating direction is longer than the length of the corresponding male power contact blade 236 of the male power terminal 206, i.e., the power contact, in the mating direction. Furthermore, the length of the male ground contact blade 224 in the mating direction is longer than the length of the male signal contact 246 of the male signal terminal 208, i.e., in the mating direction. In addition, the shape of this male ground contact blade 224 has an inclined shape 232 in which the height in the vertical direction gradually increases from the front end 230 in the mating direction toward the rear.

[0030] Furthermore, the front end 230 of the male ground contact blade 224 extends to the vicinity of the mating end 220 of the base housing 202 (see Figure 5(C)). Here, the vicinity of the mating end 220 of the base housing 202 includes the position at the same position as the mating end 220 in the front-rear direction, or a position set back by the amount of the manufacturing tolerance.

[0031] The first plate 226 is a flat plate positioned parallel to the male ground contact blade 224 and is embedded and supported within the base housing 202 by insert molding. The length of the first plate 226 in the fitting direction is shorter than the length of the male ground contact blade 224 in the fitting direction, but it may be the same length as the male ground contact blade 224. Furthermore, the lower end of the first plate 226 is provided with a ground contact 234 for substrate mounting, which is exposed from the lower surface of the bottom plate 212 of the base housing 202 when it is fixed within the base housing 202.

[0032] The male ground contact blade 224 and the first plate body 226 may be configured such that their rear ends are connected, or their rear lower ends are connected, instead of their rear upper ends being connected by the connecting portion 228.

[0033] As shown in Figure 5(B), the male power terminal 206 is made of a conductive material and includes a male power contact blade 236 and a second plate 238 arranged parallel to each other. The rear upper ends of the male power contact blade 236 and the second plate 238 are connected to each other by a connecting portion 240, resulting in the male power terminal 206 having an overall U-shape. The male power contact blade 236 acts as a power contact and connects to the power contact 306 of the socket connector 30 when mated.

[0034] The male power terminal 206 has a shape similar to the male ground terminal 204, but the length of the male power contact blade 236 in the mating direction is shorter than the length of the male ground contact blade 224 in the mating direction. Furthermore, the mating-direction tip portion of the male power contact blade 236, i.e., the front end 242, does not have an inclined shape 232 like the male ground contact blade 224. That is, the front end 242 is a straight end face that extends perpendicularly to the front-rear direction and the width direction.

[0035] Furthermore, the front end 242 of the male power contact blade 236 is positioned to be set back a predetermined distance from the mating end 220 of the base housing 202 (see Figure 5(B)). For example, the front end 242 of the male power contact blade 236 is positioned to be set back 1 mm or more from both or either the mating end 220 of the base housing 202 and the front end 230 of the male ground contact blade 224.

[0036] The second plate 238 is a flat plate positioned parallel to the male power contact blade 236 and is embedded and supported within the base housing 202 by insert molding. The length of the second plate 238 in the mating direction is shorter than the length of the male power contact blade 236 in the mating direction, but it may be the same length as the male power contact blade 236. Furthermore, a power contact 244 for board mounting is provided at the lower end of the second plate 238, which is exposed from the lower surface of the bottom plate 212 of the base housing 202 when it is fixed within the base housing 202.

[0037] As shown in Figure 2, in this embodiment, seven male signal terminals 208 are arranged between the male ground terminal 204 and the male power terminal 206. Since the seven male signal terminals 208 have the same shape, only one will be described as a representative example. The male signal terminal 208 has a male signal contact 246 that is exposed within the mating opening 222 of the base housing 202 and extends forward, and a board mounting signal contact 248 that is exposed from the lower surface of the bottom plate 212 of the base housing 202 and extends rearward.

[0038] The male signal contact 246 is a pin shape extending in the front-to-back direction, but it may also be a blade shape formed from a long flat plate in the front-to-back direction. The rear ends of the male signal contact 246 and the board mounting signal contact 248 are connected by a connector 250. The connector 250 is embedded and supported in the rear plate 218 of the base housing 202 by insert molding.

[0039] The mating length of the male signal contact 246 is shorter than the mating length of the male power contact blade 236, which is the power contact. Furthermore, the front end 252 of the male signal contact 246 is positioned behind the front end 242 of the male power contact blade 236.

[0040] Next, the socket connector 30 will be described with reference to Figure 4. As shown in Figure 4, the socket connector 30 comprises a socket housing 302, a female ground terminal 304, a female power terminal 306, and a female signal terminal 308. The female ground terminal 304, the female power terminal 306, and the female signal terminal 308 are arranged and supported in the socket housing 302 parallel to the width direction.

[0041] The socket housing 302 includes a header portion 310 and a frame portion 312. The header portion 310 is a rectangular parallelepiped with a width and vertical thickness that are inserted into and fitted into the mating opening 222 of the base housing 202, and the female ground terminal 304, female power terminal 306, and female signal terminal 308 described above are arranged inside. The frame portion 312 is located on the front side of the header portion 310 and has a flange shape that protrudes significantly more in the width and upward than the header portion 310. The front surface 314 of the frame portion 312 has openings for the ground terminal 316, a power terminal 318, and a signal terminal 320. The female ground terminal 304 and the ground wire 502 connected to this female ground terminal 304 are inserted into the ground terminal opening 316. Similarly, the female power terminal 306 and the power wire 504 to which this female power terminal 306 is connected are inserted into the power terminal opening 318. A female signal terminal 308 and a signal wire 506 connected to this female signal terminal 308 are inserted into the signal terminal opening 320.

[0042] The female gland terminal 304 has a gland wire crimping section 322 and a female gland contact 324. The gland wire crimping section 322 is the part of the female gland terminal 304 on the front side in the mating direction, and has an insulating coating gripping section 322a and a core wire crimping section 322b, both of which are U-shaped and have two gripping pieces. The insulating coating gripping section 322a receives the insulating coating of the gland wire 502 between the two gripping pieces and crimps it. The core wire crimping section 322b receives the core wire of the gland wire 502 between the two gripping pieces and crimps it.

[0043] The female ground contact 324 has a contact portion 324a on its rear end side, which has an Ω-shaped cross-section in a virtual plane extending vertically and horizontally, and a guide portion 324b on the ground wire crimping portion 322 side, which is U-shaped and open at the bottom. The male ground contact blade 224 of the male ground terminal 204 is inserted into the contact portion 324a, and an electrical connection is established when the contact portion 324a grips the male ground contact blade 224. The guide portion 324b is held and fixed within the ground terminal opening 316 of the socket housing 302.

[0044] The female power terminal 306 has the same structure as the female ground terminal 304, except that its position within the power terminal opening 318 is different from that of the female ground terminal 304 within the ground terminal opening 316 (see Figure 7).

[0045] The female power terminal 306 has a power wire crimping section 326 and a female power contact 328. The power wire crimping section 326 is the part of the female power terminal 306 on the front side in the mating direction, and has an insulating coating gripping section 326a and a core wire crimping section 326b, both of which are U-shaped and have two gripping pieces. The insulating coating gripping section 326a receives the insulating coating of the power wire 504 between the two gripping pieces and crimps it. The core wire crimping section 326b receives the core wire of the power wire 504 between the two gripping pieces and crimps it.

[0046] The female power contact 328 has a contact portion 328a on its rear end side, which has an Ω-shaped cross-section in a virtual plane extending vertically and horizontally, and a guide portion 328b on the power wire crimping portion 326 side, which is U-shaped and open at the bottom. The male power contact blade 236 of the male power terminal 206 is inserted into the contact portion 328a, and an electrical connection is established when the contact portion 328a grips the male power contact blade 236. The guide portion 328b is held and fixed within the power terminal opening 318 of the socket housing 302.

[0047] As is clear from Figure 7, the female ground terminal 304 and the female power terminal 306 are configured such that, within the socket housing 302, the contact portion 324a of the female ground terminal 304 is positioned further rearward in the mating direction than the contact portion 328a of the female power terminal 306.

[0048] The female signal terminal 308 has a signal wire crimping section 330 and a female signal contact 332. The signal wire crimping section 330 is the front part of the female signal terminal 308 and has an insulating coating gripping section 330a and a core wire crimping section 330b, each with a U-shape and two gripping pieces. The insulating coating gripping section 330a receives and grips the insulating coating of the signal wire 506 between the two gripping pieces. The core wire crimping section 330b receives the core wire of the signal wire 506 between the two gripping pieces and crimps it.

[0049] The female signal contact 332 has a contact portion 332a on its rear end side, which has a U-shaped cross-section in a virtual plane extending in the vertical and width directions. The male signal contact 246 of the male signal terminal 208 is inserted into the contact portion 332a, and an electrical connection is established when the contact portion 332a clamps the male signal contact 246. The bottom of the contact portion 332a is held and fixed within the signal terminal opening 320 of the socket housing 302.

[0050] The assembly and operation of the electrical connector 10 described above will now be explained. As described above, the male ground terminal 204, male power terminal 206, and male signal terminal 208 are embedded and fixed into the base housing 202 by insert molding. As a result, the male ground contact blade 224, male power contact blade 236, and male signal contact 246 protrude forward from the rear plate 218 into the mating opening 222.

[0051] In this configuration, the mating length of the male ground contact blade 224 is longer than the mating length of the male power contact blade 236, and the front end 230 of the male ground contact blade 224 is located further forward in the mating direction than the front end 242 of the male power contact blade 236. Furthermore, the front end 230 of the male ground contact blade 224 extends to the vicinity of the mating end 220 of the base housing 202. On the other hand, the front end 242 of the male power contact blade 236 is located a predetermined distance backward in the mating direction from the mating end 220 of the base housing 202 (see Figures 5(B) and 5(C)).

[0052] Furthermore, the ground wire 502 is connected to the ground wire crimping section 322 of the female ground terminal 304, the power wire 504 is connected to the power wire crimping section 326 of the female power terminal 306, and the signal wire 506 is connected to the signal wire crimping section 330 of the female signal terminal 308. Then, the female ground terminal 304, female power terminal 306, and female signal terminal 308, to which the electric wires 50 are connected, are inserted into the ground terminal opening 316, power terminal opening 318, and signal terminal opening 320 of the socket housing 302 and secured.

[0053] In this case, as shown in Figure 7, within the socket housing 302, the rear end of the contact portion 324a of the female ground terminal 304 in the mating direction is located further rear than the rear end of the contact portion 328a of the female power terminal 306 in the mating direction.

[0054] Next, the base housing 202 is mounted onto the printed circuit board 40. The ground contact 234, power contact 244, and signal contact 248 for board mounting, which are exposed on the underside of the bottom plate 212 of the base housing 202, are soldered to the patterns on the printed circuit board 40, thereby establishing electrical and mechanical connections.

[0055] Figures 5(A) and 5(C) show the base connector 20 and socket connector 30 before mating. As described above and as is clear from comparing Figures 5(B) and 5(C), the front end 230 of the male ground contact blade 224 is located further forward in the mating direction than the front end 242 of the male power contact blade 236. Also, the front end 230 of the male ground contact blade 224 is in approximately the same position as the mating end 220 of the base housing 202. On the other hand, the front end 242 of the male power contact blade 236 is located a predetermined distance backward from the mating end 220 of the base housing 202.

[0056] Next, the mating of the base connector 20 and the socket connector 30 is initiated. When mating begins, as shown in Figures 6(A)-6(C) and 7, the rear portion of the header portion 310 of the socket housing 302 in the mating direction is inserted into the mating opening 222 of the base housing 202. At this time, the male ground contact blade 224 is inserted into and clamped by the contact portion 324a of the female ground contact 324 of the female ground terminal 304 almost simultaneously with the start of mating, and electrical conductivity begins. This is because the front end 230 of the male ground contact blade 224 is located further forward in the mating direction than the front end 242 of the male power contact blade 236. On the other hand, at this point, the front end 242 of the male power contact blade 236 has not yet reached the contact portion 328a of the female power terminal 306, and electrical conductivity has not yet begun.

[0057] When the base connector 20 and the socket connector 30 are moved further relative to each other in the mating direction, the male power contact blade 236 is inserted into and clamped by the contact portion 328a of the female power contact 328 of the female power terminal 306, and electrical conductivity begins. That is, electrical conductivity between the male power contact blade 236 and the female power contact 328 begins with a time delay compared to electrical conductivity between the male ground contact blade 224 and the female ground contact 324.

[0058] Next, when the base connector 20 and the socket connector 30 are moved further relative to each other in the mating direction, they reach the fully mated state shown in Figures 8(A)-8(C). At this time, the male signal contact 246 is inserted into and held by the contact portion 332a of the female signal contact 332, and electrical conduction begins. As is clear from Figure 7, the front end 252 of the male signal contact 246 is positioned further back in the mating direction than the front end 230 of the male ground contact blade 224 and the front end 242 of the male power contact blade 236. Therefore, electrical conduction between the male signal contact 246 and the female signal contact 332 begins with a time delay compared to electrical conduction between the male power contact blade 236 and the female power contact 328.

[0059] Furthermore, at this time, the front end 230 of the male ground contact blade 224 extends beyond the rear end portion in the mating direction of the core wire crimping portion 322b of the female ground terminal 304 towards the socket connector 30. However, because the male ground contact blade 224 has an inclined shape 232 that gradually rises from the front end 230 toward the rear, the male ground contact blade 224 does not interfere with the core wire crimping portion 322b.

[0060] In the above embodiment, an example was described in which the mating opening 222 of the base connector 20 opens in a direction parallel to the printed circuit board 40, i.e., towards the front, and the socket connector 30 is mated in a direction parallel to the printed circuit board 40. However, this disclosure is not limited to the above embodiment. The mating opening of the base connector may open in a direction perpendicular to the printed circuit board 40, and the socket connector 30 may be mated perpendicular to the printed circuit board 40.

[0061] Furthermore, the above embodiment describes an example in which the base connector 20 is surface-mounted on the printed circuit board 40. However, this disclosure is not limited to the above embodiment. The male ground terminal 204, male power terminal 206, and male signal terminal 208 may each be provided with downward-projecting pin contacts instead of board mounting contacts, and these may be inserted into through-holes of the printed circuit board 40 and soldered.

[0062] Furthermore, the configuration may be modified by swapping the left and right sides of the above embodiment or reversing the top and bottom. In addition, in the above embodiment, an example was described in which so-called male type contacts are incorporated into the base connector 20, while so-called female type contacts are incorporated into the socket connector 30. However, these functions may be swapped so that female type contacts are incorporated into the base connector 20 mounted on the printed circuit board 40, and male type contacts are incorporated into the socket connector 30 facing it.
