The present application provides a board-to-board connector and a male connector thereof for solving the problems of the conventional board-to-board connector that the assembling is difficult and the electrical connection stability is poor when the assembling deviation occurs, and the present application will be described more fully with reference to the related drawings.

Referring to fig. 1, the male connector 1000 includes a male housing 1100, a floating member 1200 and a male terminal 1300, and referring to fig. 2, the male terminal 1300 includes a first connecting portion 1350 and a second connecting portion 1340, the first connecting portion 1350 and the second connecting portion 1340 are arranged at an interval, the first connecting portion 1350 is fixedly connected to the male housing 1100, the second connecting portion 1340 is fixedly connected to the floating member 1200, and the floating member 1200 is elastically connected to the inside of the male housing 1100.

The male housing 1100 of the male connector 1000 is elastically connected to the floating member 1200, and the floating member 1200 is disposed inside the male housing 1100, so that when the floating member 1200 is not subjected to a force (except for gravity), the floating member 1200 is located at an exact position inside the male housing 1100, when the floating member 1200 is subjected to a force, the floating member 1200 floats in the male housing 1100 along with the force, and when the force disappears, the floating member 1200 returns to the exact position. The male socket terminal 1300 is a conductor, and the first connecting portion 1350 and the second connecting portion 1340 of the male socket terminal 1300 are respectively connected to the male socket housing 1100 and the floating member 1200, thereby achieving the electrical connection of the male socket housing 1100 and the floating member 1200. And the first and second connection portions 1350 and 1340 are spaced apart such that the float member 1200 has a space to float with respect to the male housing 1100. With the above arrangement, when the floating member 1200 is forced to float, the male housing 1100 can still be kept still, and the floating member 1200 and the male housing 1100 still have stable electrical connection.

The floating member 1200 is used to connect to the female connector 2000 and establish electrical connection with the female connector 2000. When the female connector 2000 is connected to the floating member 1200, if the female connector 2000 floats with respect to the male connector 1000, a force is transmitted to the floating member 1200, so that the floating member 1200 floats following the female connector 2000. With the above arrangement, when the female connector 2000 is forced to float, the male housing 1100 can still be kept still, and the female connector 2000 and the male housing 1100 still have stable electrical connection.

In one embodiment, referring to fig. 1, the male socket terminal 1300 has elasticity, and the floating member 1200 is elastically connected in the male socket housing 1100 through the male socket terminal 1300. Since the male socket terminal 1300 is a conductor, and the common conductor is metal, the metal also has elasticity, so that the male socket terminal 1300 as metal is used as an elastic member for connecting the floating member 1200 and the male socket housing 1100, the space in the male socket housing 1100 can be saved, the structure of the male socket connector 1000 can be simplified, and the cost can be saved.

In one embodiment not shown in the figures, the float 1200 is resiliently coupled to the male housing 1100 by a spring. The spring is used as a standard elastic device and has stronger elastic force and service life, so that the spring is used as an elastic member for connecting the floating member 1200 and the male socket housing 1100, on one hand, the service life of the male socket connector 1000 is prolonged, on the other hand, the electrical connection between the floating member 1200 and the male socket housing 1100 has better flexibility, for example, the floating member 1200 and the male socket housing 1100 are connected by using a better flexible wire, and further, the floating flexibility of the floating member 1200 relative to the male socket housing 1100 is improved.

In one embodiment, referring to fig. 2, a deformation portion 1370 is disposed between the first connecting portion 1350 and the second connecting portion 1340 of the male socket terminal 1300, and the deformation portion 1370 is easily deformed by a force. Referring to fig. 2 in conjunction with fig. 1, the first connecting portion 1350 is fixedly connected to the male housing 1200, and the male housing 1200 is regarded as stationary, so that the first connecting portion 1350 is also stationary. Meanwhile, the second connection portion 1340 connected to the floating member 1200 floats following the floating member 1200.

Therefore, when the second connecting portion 1340 floats with respect to the first connecting portion 1350, as shown in fig. 2, when the second connecting portion 1340 floats up and down, the first deformation point 1310 between the second connecting portion 1340 and the deformation portion 1370 is bent, and at the same time, the second deformation point 1320 between the deformation portion 1370 and the first connecting portion 1350 is bent, so that the second connecting portion 1340 is floated up and down with respect to the first connecting portion 1350. When the second connecting portion 1340 floats in and out of the plane of the picture, the first deformation point 1310 between the second connecting portion 1340 and the deformation portion 1370 is bent, and meanwhile, the second deformation point 1320 between the deformation portion 1370 and the first connecting portion 1350 is bent, so that the second connecting portion 1340 floats up and down relative to the first connecting portion 1350.

In one embodiment, referring to fig. 2, a buffering portion 1330 is disposed between the first connecting portion 1350 and the second connecting portion 1340 of the male socket terminal 1300, and the buffering portion 1330 is bent in an S-shape. When the second connecting portion 1340 floats in only one direction with respect to the first connecting portion 1350, a distance between the first connecting portion 1350 and the second connecting portion 1340 is increased. If a straight line is formed between the first connecting portion 1350 and the second connecting portion 1340, the distance between the first connecting portion 1350 and the second connecting portion 1340 is kept constant along with the left and right floating of the second connecting portion 1340 with respect to the first connecting portion 1350 when the second connecting portion 1340 floats up and down with respect to the first connecting portion 1350. The S-shaped buffer portion 1330 is disposed between the first connecting portion 1350 and the second connecting portion 1340, which is beneficial for the S-shaped area of the buffer portion 1330 to be elongated when the distance between the first connecting portion 1350 and the second connecting portion 1340 is increased, thereby ensuring that the second connecting portion 1340 does not generate an additional offset relative to the first connecting portion 1350.

Referring to fig. 1, when the female connector 2000 is connected to the floating member 1200, if the female connector 2000 floats up and down according to the view angle of fig. 1, the floating member 1200 does not float left and right under the condition that the buffer portion 1330 is bent to have an S-shape, so that the relative positions of the female connector 2000 and the floating member 1200 are always stable, and further, the electrical connection between the female connector 2000 and the floating member 1200 is always stable.

Optionally, a buffer 1330 is disposed between the first connecting portion 1350 and the second connecting portion 1340 of the male socket terminal 1300, and the buffer 1330 is curved in a spiral shape. For the same reason as the above embodiment, the electrical connection between the socket connector 2000 and the floating member 1200 can be ensured to be stable by the above arrangement.

In one embodiment, referring to fig. 2, the deformation portion 1370 includes a buffer portion 1330, in other words, the buffer portion 1330 is a portion of the deformation portion 1370.

In one embodiment, referring to fig. 1, the floating member 1200 includes a base 1210 and a pressing portion 1220 connected to the base 1210, the base 1210 is provided with a terminal groove 1240 for receiving the male socket terminal 1300, and the pressing portion 1220 presses the male socket terminal 1300 in the terminal groove 1240 in the middle of the base 1210. The floating member 1200 needs to be stably connected with the male socket terminal 1300 to establish stable electrical connection with the male socket housing 1100, and therefore, a pressing portion 1220 is provided, and the pressing portion 1220 is used for pressing the male socket terminal 1300 which needs to be connected with the floating member 1200, so as to enhance the stability of the connection between the male socket terminal 1300 and the floating member 1200. Meanwhile, the base body 1210 is provided with a terminal groove 1240 used for accommodating the male socket terminal 1300, the male socket terminal 1300 is placed in the terminal groove 1240, on one hand, the pressing part 1220 is convenient to press the male socket terminal 1300, on the other hand, the arrangement and the trend of the male socket terminal 1300 on the floating piece 1200 are fixed, the repeated plugging and unplugging between the female socket connector 2000 and the floating piece 1200 are avoided, and the electrical connection between the female socket connector 2000 and the floating piece 1200 is kept stable.

In one embodiment, referring to fig. 1 and 2, the floating member 1200 includes a wedge portion 1230, the wedge portion 1230 is located between the first connecting portion 1350 and the second connecting portion 1340 of the male socket terminal 1300, and the tip of the wedge portion 1230 is far away from the second connecting portion 1340. With the above design satisfied, when the floating member 1200 floats relative to the male housing 1100, the deformation angle between the second connecting portion 1340 and the deformation portion 1370 is limited to a certain range, i.e., a space range between the adjacent wedge portions 1230, so as to prevent the male housing terminal 1300 from being damaged due to excessive deformation.

Specifically, the wedge portion 1230 includes a first wedge portion 1231 and a second wedge portion 1232, and the slopes of the first wedge portion 1231 and the second wedge portion 1232 are perpendicular to each other. In other words, the second wedge 1232 is provided in the direction in which the floating member 1200 floats up and down in order to limit the up and down deformation angle between the second connecting portion 1340 and the deformation portion 1370; the first wedge 1231 is provided in a direction in which the floating member 1200 floats toward the inside and outside of the paper surface to limit a deformation angle toward the inside and outside of the paper surface between the second connecting portion 1340 and the deformation portion 1370.

In one embodiment, the male housing 1100 is provided with a mounting groove 1110, and the first connecting portion 1350 is snapped into the mounting groove 1110. When the first connecting portion 1350 is engaged in the mounting groove 1110, the first connecting portion 1350 is not dragged by the floating of the second connecting portion 1340. Through the above arrangement, the connection stability of the first connection part 1350 can be ensured, and the electrical connection stability of the male connector 1000 can be further ensured.

In one embodiment, referring to fig. 1, an end of the base body 1210 of the floating member 1200 away from the first connecting portion 1350 is wedge-shaped, that is, the thickness of the base body 1210 gradually increases from the end to the middle of the base body 1210. With the above arrangement, the base body 1210 of the float 1200 is more easily inserted into the female connector 2000.

In one embodiment, referring to fig. 1, two opposite side surfaces of the floating member 1200 are respectively connected with a plurality of male socket terminals 1300, and the male socket terminals 1300 located at the two opposite side surfaces of the floating member 1200 are mirror-symmetrical. The above arrangement ensures that the spring force received by the floating member 1200 is more stable on the one hand, and the other hand is required for the symmetry of the male socket terminal 1300.

In one embodiment, referring to fig. 2, a matching portion 1380 is further disposed between the second deformation point 1320 and the first connection portion 1350 on the male socket terminal 1300, and the matching portion 1380 and the first connection portion 1350 form a certain included angle, so that the first connection portion 1350 and the second connection portion 1340 are not on the same straight line. The floating member 1200 is disposed inside the male housing 1100, the first connecting portion 1350 is connected to the male housing 1100, and the second connecting portion 1340 is connected to the floating member 1200, so that the first connecting portion 1350 and the second connecting portion 1340 cannot be aligned, and the deformation portion 1370 between the first connecting portion 1350 and the second connecting portion 1340 is in a stress environment for a long time. In order to prevent the deformation portion 1370 between the first connecting portion 1350 and the second connecting portion 1340 from being in a large stress environment for a long time and causing unstable connection or damage to the male socket terminal 1300, a matching portion 1380 is provided to reduce the stress of the deformation portion 1370 between the first connecting portion 1350 and the second connecting portion 1340 under a normal state, that is, the stress of the floating member 1200 without stress.

Referring to fig. 3a to 3c, the floating state of the female connector 2000 to both sides of the male connector 1000 before and after the male connector 1000 is connected to the female connector 2000 will be further described.

Referring to fig. 3b in the middle, the operation status of each component in the male connector 1000 is schematically illustrated when the female connector 2000 is not floating. When the female connector 2000 is not floated, the floating member 1200 is in an unstressed state, so that the male connector terminal 1300 is not deformed, and the electrical connection state between the female connector 2000 and the male connector 1000 is maintained.

Please refer to fig. 3a, which is a schematic diagram illustrating the operation status of each component in the male connector 1000 when the female connector 2000 floats toward the left side of the male connector 1000. The female connector 2000 floats to the left with respect to the male connector 1000 and gives a leftward force to the floating member 1200 of the male connector 1000, so that the floating member 1200 follows the leftward floating. At this time, the male socket terminal 1300 is deformed at the first deformation point 1310 and the second deformation point 1320, so that the deformation portion 1370 of the male socket terminal 1300 is bent relative to the floating member 1200. Therefore, when the floating member 1200 floats to the left side of the male connector 1000, the male connector housing 1100 can still be kept stationary, and only the deformation portion 1370 is elastically deformed in the male connector 1000, so that the electrical connection state between the female connector 2000 and the male connector 1000 is maintained.

Please refer to fig. 3c, which is a schematic diagram illustrating the operation status of each component in the male connector 1000 when the female connector 2000 floats towards the right side of the male connector 1000. The female connector 2000 floats to the right with respect to the male connector 1000 and gives a force to the floating member 1200 of the male connector 1000 to the right, so that the floating member 1200 follows the floating to the right. At this time, the male socket terminal 1300 is deformed at the first deformation point 1310 and the second deformation point 1320, so that the deformation portion 1370 of the male socket terminal 1300 is bent relative to the floating member 1200. Therefore, when the floating member 1200 floats to the right side of the male connector 1000, the male connector housing 1100 can still be kept stationary, and only the deformation portion 1370 of the male connector 1000 is elastically deformed, so that the electrical connection state between the female connector 2000 and the male connector 1000 is maintained.

To sum up, when the female connector 2000 floats to both sides of the male connector 1000, only the deformation portion 1370 of the male connector 1000 is elastically deformed, so that the electrical connection state between the female connector 2000 and the male connector 1000 is maintained.

Referring to fig. 4a to 4c, the state before and after the female connector 2000 floats to the insertion depth of the male connector 1000 when the male connector 1000 is connected to the female connector 2000 will be further described.

Referring to fig. 4b in the middle, the operation status of each component in the male connector 1000 is schematically illustrated when the female connector 2000 is not floating. The female connector 2000 includes female socket terminals 2200, and the female socket terminals 2200 are electrically connected to the male socket terminals 1300 in a contact manner. The male socket terminal 1300 further includes an internal conductive portion 1360, the internal conductive portion 1360 is exposed on the surface of the floating member 1200, is located at an end portion of the male socket terminal 1300 close to the pressing portion 1220, and abuts against the female socket terminal 2200, and establishes an electrical connection with the female socket terminal 2200. When the female connector 2000 does not float, the female socket terminal 2200 is almost abutted against the middle of the internal conductive portion 1360, and the female socket terminal 2200 and the internal conductive portion 1360 are stably electrically connected.

Fig. 4a is a schematic view showing the working states of the components in the male connector 1000 when the female connector 2000 is inserted into the male connector 1000 to a deep floating position. When the female connector 2000 is inserted deeper into the male connector 1000, the female connector 2000 approaches the pressing portion 1220 more and the female socket terminal 2200 is substantially abutted against the end of the inner conductive portion 1360 near the pressing portion 1220, so that the female socket terminal 2200 and the inner conductive portion 1360 are electrically connected stably.

Fig. 4c is a schematic view showing the working states of the components in the male connector 1000 when the female connector 2000 is slightly floated when inserted into the male connector 1000. When the female connector 2000 is inserted into the male connector 1000 more shallowly, the female connector 2000 is away from the pressing portion 1220, and the female socket terminal 2200 is substantially abutted against an end of the inner conductive portion 1360 away from the pressing portion 1220, so that the female socket terminal 2200 and the inner conductive portion 1360 have stable electrical connection.

In summary, when the female connector 2000 is floated in the depth of insertion into the male connector 1000, the female socket terminal 2200 establishes a stable electrical connection with the inner conductive portion 1360.

Referring to fig. 5 a-5 b, a state in which the female connector 2000 floats toward both sides of the male connector 1000 when the male connector 1000 is connected to the female connector 2000 will be further described.

Fig. 5a is a schematic view showing the working states of the components in the male connector 1000 when the female connector 2000 floats to the right of the male connector 1000. The female connector 2000 floats to the right with respect to the male connector 1000 and gives a right force to the floating member 1200 of the male connector 1000, so that the floating member 1200 follows the floating to the right. At this time, the deformation 1370 of the male socket terminal 1300 bends relative to the floating member 1200, and the male socket terminal 1300 is offset from the female socket terminal 2200 by a distance D3, leaving a gap D1 between the left side of the floating member 1200 and the male connector 1000. Therefore, when the floating member 1200 floats to the right of the male connector 1000, the male connector housing 1100 can still be kept stationary, and only the deformation portion 1370 of the male connector 1000 is elastically deformed, so that the electrical connection state between the female connector 2000 and the male connector 1000 is maintained.

In one embodiment, D1 is 2mm and D3 is 1 mm. Wherein D3 is equal to one-half of D1, when D1 and D3 are too small, the floating range of the female connector 2000 is not enough, and when D1 and D3 are too large, the floating member 1200 is not stable enough, and it is easy to cause the male connector 1300 to be deformed too much and damage.

Fig. 5b is a schematic view showing the working states of the components in the male connector 1000 when the female connector 2000 floats to the left of the male connector 1000. The female connector 2000 floats to the left with respect to the male connector 1000 and gives a leftward force to the floating member 1200 of the male connector 1000, so that the floating member 1200 follows the leftward floating. At this time, the deformation 1370 of the male socket terminal 1300 bends relative to the floating member 1200, and the male socket terminal 1300 is offset from the female socket terminal 2200 by a distance D4, leaving a gap D2 between the left side of the floating member 1200 and the male connector 1000. Therefore, when the floating member 1200 floats to the left of the male connector 1000, the male connector housing 1100 can still be kept stationary, and only the deformation portion 1370 of the male connector 1000 is elastically deformed, so that the electrical connection state between the female connector 2000 and the male connector 1000 is maintained.

In summary, when the female connector 2000 floats in any direction within a certain range with respect to the male connector 1000, the electrical connection state between the female connector 2000 and the male connector 1000 can be maintained stably.

In one embodiment, D2 is 2mm and D4 is 1 mm. Wherein D4 is equal to one-half of D2, when D4 and D2 are too small, the floating range of the female connector 2000 is not enough, and when D4 and D2 are too large, the floating member 1200 is not stable enough, and it is easy to cause the male connector 1300 to be deformed too much and damage.

The present application further provides a board-to-board connector, please refer to fig. 1, including a female connector 2000 and any one of the above-mentioned male connector 1000, where the female connector 2000 includes a female socket terminal 2200 and a port 2100 for inserting the floating element 1200, and one end of the female socket terminal 2200 is connected in the port 2100 and abuts against the male socket terminal 1300 to establish a stable electrical connection with the male socket terminal 1300.

In one embodiment, the female connector 2000 further includes an abutting portion 2110, the end of the female connector 2200 abutting the male connector 1300 is bent, and the side of the bent portion protruding abuts the male connector 1300, and the end of the female connector 2200 abutting the male connector 1300 abuts the abutting portion 2110. The end of the female socket terminal 2200 abutting the male socket terminal 1300 is bent, so that the female socket terminal 2200 has an elastic force pressing against the male socket terminal 1300, thereby enhancing the stability of the electrical connection between the female socket terminal 2200 and the male socket terminal 1300. When the female socket terminal 2200 abuts on the male socket terminal 1300, the bent portion of the female socket terminal 2200 deforms and extends towards two ends of the bent portion, so that one end of the bent portion abuts against the abutting portion 2110, which is beneficial to restricting the extending direction of the bent portion and preventing the female socket terminal 2200 from stabbing the male socket connector 1000 or being stuck in the male socket connector 1000.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
