The technical solution of the present invention will be further described below by way of specific embodiments and in conjunction with the accompanying drawings. The description of the various embodiments of the present invention is intended to be illustrative of the present invention, and is not to be construed as limiting.

1A and 1B illustrate an embodiment of an electrical connector 1000 in accordance with the present invention. In one example, electrical connector 1000 can be a female or receptacle type power connector that mates with a mating connector, such as a male connector or a plug connector, to power an electronic device.

As shown, the electrical connector 1000 includes a housing 1100 and a pair of contacts 1200 disposed within the housing 1100. The pair of contacts can be electrically connected to a substrate 1500 (see FIG. 2B), such as It is fixed to the electronic device by screws. Each contact 1200 includes a resilient terminal 1210 that is configured to electrically contact an insertion terminal FT (shown in Figures 3 and 7B) of a mating connector (not shown). The electrical connector also includes a separation device 1300 that is configured to be movable between a first position and a second position in which the separation device 1300 flexes two of the pair of contacts 1200 The terminals 1210 are separated so that the insertion terminal FT is inserted between the two elastic terminals 1210, and in the second position, the separating device 1300 is withdrawn from between the two elastic terminals 1210, so that the two elastic terminals 1210 can be close to each other. To clamp the insertion terminal FT. Generally, the housing 1100 is made of an insulating material such as plastic, for example, by injection molding, and the elastic terminal 1210 is provided by A resilient conductive material such as a metal sheet is made, for example, by molding.

2A-2C illustrate the electrical connector 1000 in an initial state with the separation device 1300 in a first position. In the initial state, the two resilient terminals 1210 of the electrical connector are separated by a separating device 1300 to form an accommodation space for the insertion terminal that is ready to receive the mating connector. In one example, as shown in FIGS. 2A and 2B, each contact 1200 includes a first U-shaped portion 1220 that includes a first arm 1221 and a second arm 1222, a first arm. 1221 extends downwardly to electrically connect to the substrate 1500, and each of the elastic terminals 1210 is in a direction opposite to an insertion direction R (shown in FIG. 3) along which the insertion terminal FT is inserted into the electrical connector 1000. A second arm 1222 extends. The two resilient terminals 1210 are opposite each other, relying on their own resilience, or as shown below, with a clamping device 1400 having a tendency to approach each other to maintain good electrical contact with the insertion terminals.

As shown in Figures 2A through 2C, a separation device 1300 in accordance with one embodiment of the present invention includes a first separation portion 1310 that is configured to be in a first position (as shown in Figure 2C). Or, when the separating device moves from the second position (the position shown in FIGS. 7B and 7C) to the first position, the two elastic terminals 1210 are separated to reduce the insertion of the insertion terminal of the mating connector. The insertion force, for example, can reduce the insertion force to 10 Lbs to 15 Lbs, thereby avoiding problems such as component damage, circuit failure, and the like due to a large insertion force in a conventional connector.

Further, according to the present invention, since the separating device 1300 is provided, it is ensured that the distance between the two elastic terminals 1210 is sufficiently large, even if the insertion terminal of the mating connector is caused by the tolerance existing in the manufacturing, assembly process, or the like. The insertion direction is offset with respect to the central axis between the two elastic terminals 1210 (ie, misalignment), and the insertion terminal of the mating connector can also be inserted into the two elastic terminals 1210 of the electrical connector 1000 of the present invention. Between the two connectors is achieved. In other words, the electrical connector 1000 of the present invention provides a floating space for accommodating the insertion terminal of the mating connector by providing the separating device 1300, for example, an offset distance of about ±1.4 mm can be achieved.

In one embodiment, the separation device 1300 can also include a body portion 1330, for example, in a generally plate shape. The first separating portion 1310 extends from one end of the body portion 1330 in a direction opposite to the insertion direction R of the insertion terminal, and may have a tip end to facilitate insertion between the two elastic terminals 1210. A pressing portion 1320 may be provided at the other end of the body portion opposite to the first separating portion 1310, by means of which the separating device 1300 can be pushed to move between the first position and the second position. As will be described below, the push portion 1320 can be configured to prevent the separation device 1300 from moving further in a direction opposite the insertion direction when the separation device 1300 is in the first position.

As noted above, the electrical connector 1000 of the present invention can also be provided with a clamping device 1400, as shown in Figure 2B, which includes a pair of clamping arms 1430 that are configured to be clamped Two resilient terminals 1210 are provided to maintain electrical contact between the two resilient terminals 1210 and the insertion terminal FT. In this embodiment, even if the insertion terminal of the mating connector is not centered into the electrical connector 1000 due to tolerances or the like, the two connectors can be realized by the clamping device 1400 clamping the two elastic terminals 1210. A good electrical connection between the two. As shown in FIG. 6A, a plurality of sliding grooves 1211 may be formed on the outer surface of each of the elastic terminals 1210. The end portions of the corresponding clamping arms 1430 may be formed with corresponding plurality of protrusions 1431, and the protrusions 1431 are joined to each other. The sliding slot 1211 can slide in the sliding slot 1211 during the separation and approach of the two elastic terminals 1210, so that the clamping device 1400 can always maintain the clamping of the two elastic terminals 1210, and even can be compliantly connected. The offset of the insertion terminal of the device clamps the two elastic terminals 1210.

The body portion 1330 can be provided with a second separating portion 1331 configured to push the pair of clamping arms 1430 of the clamping device 1400 away from each other in the first position, thereby further reducing the insertion terminal of the insertion mating connector The required insertion force. As shown in FIG. 2C, the body portion 1330 may have a substantially rectangular plate shape, and a shoulder portion is formed at a portion of the first separating portion 1310 extending from the body portion 1330 to constitute a second separating portion 1331.

According to an embodiment of the present invention, the second separating portion 1331 may be configured to be separated When the device 1300 is moved from the second position to the first position, the pair of clamping arms 1430 are pushed away from each other before the first separating portion 1310 separates the two elastic terminals 1210 to reduce the resistance to separate the two elastic terminals. Of course, those skilled in the art can understand that when the separating device 1300 is moved from the second position to the first position, the pushing of the clamping arm 1430 by the second separating portion 1331 can be opposite to the first separating portion 1310 by the two elastic terminals 1210. The two are synchronized separately or after the first separating portion 1310 starts to separate the two elastic terminals 1210.

Further, the first separation portion 1310 may be configured to urge the pair of clamping arms 1430 away from each other before the second separation portion 1331 contacts the pair of clamping arms 1430 when the separation device 1300 is moved from the second position to the first position. For example, the second separation portion 1331 may have a larger dimension in one direction perpendicular to the insertion direction R than the first separation portion 1310. In this case, during the return of the electrical connector 1000 from the state in which the two elastic terminals 1210 are closed (see FIG. 7C) to the initial state (see FIG. 7A), the push separating device 1300 is in the opposite direction to the insertion direction R. When moving, the smaller first separating portion 1310 first contacts and pushes the pair of clamping arms 1430 of the clamping device 1400 away from each other, and then the second separating portion 1331 pushes the pair of clamping arms 1430 further away from each other and by the first A separating portion 1310 pushes the two resilient terminals 1210 apart from each other to be ready to receive the insertion terminal FT of the mating connector.

Referring again to FIG. 2B, the clamping device 1300 can be generally U-shaped as a whole, and can also include a second U-shaped portion 1410 and a pair of constrictions between the second U-shaped portion 1410 and the pair of clamping arms 1430. a narrow portion 1420, the second U-shaped portion 1410 includes a pair of side walls and a rear wall 1411 between the pair of side walls, and each narrowing portion 1420 tapers from a side wall toward a corresponding one of the clamping arms 1430 extend. The clamping device 1300 is also disposed within the housing 1100 and can surround a substantial portion of the pair of contacts 1200 to effect clamping of its resilient terminals.

In one embodiment of the present invention, a second opening or slit 1412 may be disposed in the rear wall 1411 of the second U-shaped portion 1410, and the body portion 1330 of the separating device is inserted through the first opening 1412 to be in the separating device 1300. The first opening 1412 is partially moved during movement between the first position and the second position. In this case, the pressing portion 1320 of the separating device can It is configured to abut against an outer surface of the rear wall 1411 when the separation device 1300 is in the first position to prevent the separation device 1300 from moving further in a direction opposite to the insertion direction R. For example, the pressing portion 1320 may be a portion extending from the body portion 1330 in a direction substantially parallel to the outer surface of the rear wall 1411 to form a substantially L-shape with the body portion 1330.

In one example, as shown in FIG. 2C, the body portion 1330 can also be provided with a stop member 1340 that is configured to abut against one of the rear walls 1411 when the separation device 1300 is in the second position. On the inner surface, the separation device 1300 is prevented from further moving in the insertion direction R, which prevents the separation device 1300 from falling from the clamping device 1400. For example, the stop 1340 can be a protruding portion on the surface of the body portion 1330.

As shown in Figures 4D and 6B, a second opening or slit 1223 can be formed in the second arm 1222 of each contact member 1200, as the separation device 1300 moves between the first position and the second position. The body portion 1330 and the separation portion 1310 are at least partially moved through the second opening 1223 to facilitate separation or clamping of the two resilient terminals 1210. In an example, the second opening 1223 can be formed in a portion of the first U-shaped portion 1220 other than the first arm 1221 to facilitate smooth movement of the separation device. The first opening 1412 of the clamping device 1400 and the second opening 1223 of the contact member 1200 are in the same plane, so that the pair can be contacted by the separating device 1300 and the clamping device 1400 extending through the first and second openings. The clamping force of the piece 1200 supports the clamping device 1400 on the pair of contacts 1200.

Illustrative examples of the structure and shape of the electrical connector 100 in accordance with the present invention have been described above, but those skilled in the art will appreciate that the invention is not limited thereto. Hereinafter, the fitting operation between the electrical connector of the present invention and the mating connector will be described with reference to the drawings.

1A through 2C and 7A illustrate an electrical connector 1000 in an initial state in accordance with one embodiment of the present invention. As shown, in the initial state of the electrical connector 1000, the separating device 1300 has been pushed into the first position by the pressing portion 1320, at which time the two elastic terminals 1210 of the electrical connector 1000 have been separated. The first separating portion 1310 of the device 1300 is separated, and the second separating portion 1331 pushes the two clamping arms 1430 of the clamping device 1400 to each other. Further, it is possible to reduce the insertion force required to insert the insertion terminal FT of the mating connector, and the pressing portion 1320 abuts against the rear wall 1411 of the holding device to prevent the insertion device 1300 from being inserted in the insertion direction FT with the insertion terminal FT. The opposite direction moves further.

3 to 4D and 7B show the mated state after the insertion terminal FT of the mating connector is inserted into the electrical connector 1000 of the present invention. During the transition of the electrical connector 1000 from its initial state to the mated state, the insertion terminal FT of the mating connector is inserted between the two separate resilient terminals 1210 in the insertion direction R and further pushes the separation device 1300, such as against the first The tip end of the separating portion 1310 is moved in the insertion direction R. At this time, the first separating portion 1310 is moved or retracted in the insertion direction R to be out of contact with the two elastic terminals 1210, so that the two elastic terminals 1210 are slightly close to each other for contact insertion. The terminal FT, and the second separating portion 1331 slides on the inner surface of the gripping arm 1430 in the insertion direction R. During the pulling of the separating device 1300, the first separating portion 1310 and the body portion 1330 including the second separating portion 1331 partially move through the second opening 1223 so as not to block the two elastic terminals 1210 from approaching each other and not interfering with the clamping arm. The holding of the two elastic terminals 1210 is 1430.

In the mated state as shown in FIG. 7B, the two elastic terminals 1210 closely contact the insertion terminal FT by the clamping of the clamping arm 1430 to form an electrical connection between the electrical connector 1000 and the mating connector; the separating device 1300 The first separating portion 1310 may be partially located between the pair of clamping arms 1430 or between the two second arms 1222 of the pair of contacts 1200 without applying a separate force to the contacts; the separating device 1300 The second separating portion 1331 also no longer applies a force to the clamping device to separate the clamping arms 1430, for example, between the narrowing portions 1420 or the second U-shaped portion 1410; the pressing portion 1320 of the separating device 1300 is far away The device rear wall 1411 is clamped while its stop 1340 abuts against the inner surface of the rear wall 1411 to prevent further movement of the separation device 1300 in the insertion direction R.

5 to 6C and 7C show the state after the insertion terminal of the mating connector is separated from the electrical connector 1000. In this state, the separation device 1300 remains in the second position, and there is no longer a barrier between the two resilient terminals 1210 of the contact, thus the clamping arm 1430 They are brought into contact with each other under gripping, for example, the front ends of the two elastic terminals 1210 cross each other to avoid inadvertent insertion of the insertion terminals of the mating connector. At this time, the first separating portion 1310 and the body portion 1330 including the second separating portion 1331 partially move through the second opening 1223 so as not to block the two elastic terminals 1210 from approaching each other and not disturbing the clamping arm 1430 to the two The clamping of the elastic terminal 1210. Moreover, the second separating portion 1331 of the separating device 1300 also does not apply a force to separate the pair of gripping arms 1430 to the gripping device, and in the example shown in Figure 7C, the first separating portion 1310 can be partially located in the pair of clips The arms 1430 are held between the arms 1430 so that when the electrical connector 1000 needs to be restored to its original state, the first separating portion 1310 first pushes the pair of clamping arms 1430 first, thereby separating the two resilient terminals 1210.

Contrary to the above operational sequence, when the electrical connector 1000 is restored from the state shown in FIG. 7C to the initial state as shown in FIG. 7A, that is, when the separation device 1300 is moved from the second position to the first position, As described above, the push separation device 1300 moves in a direction opposite to the insertion direction R, and the first separation portion 1310 first contacts and pushes the pair of clamp arms 1430 of the clamp device 1400 away from each other, and then is pushed by the second separation portion 1331. The pair of clamping arms 1430 are further apart from each other and the two resilient terminals 1210 are pushed apart from each other by the first separating portion 1310 to be ready to receive the insertion terminal FT of the mating connector.

As described above, the electrical connector according to the present invention is provided with a separating means for separating the two elastic terminals thereof to reduce the insertion force required to be inserted into the insertion terminal of the mating connector, for example, the insertion force can be reduced to 10 Lbs to 15Lbs, which can avoid problems such as component damage and circuit failure caused by the large insertion force in the conventional connector. Moreover, since the separating means is provided, it is ensured that the distance between the two elastic terminals is sufficiently large, even if the insertion terminal of the mating connector is inserted in a direction relative to the two due to tolerances existing in manufacturing, assembly processes, and the like. The center axis between the elastic terminals is offset (ie, misaligned), and the insertion terminal of the mating connector can also be inserted between the two elastic terminals of the electrical connector of the present invention to realize the two connectors Cooperation. In other words, the electrical connector of the present invention provides an insertion terminal for accommodating a mating connector by providing a separating device. The larger floating insertion space, for example, can achieve an offset distance of about ±1.4 mm.
