Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a plug-in conductive terminal and a plug-in floating connector. Background Art

[0002] In various electronic systems, electrical connectors are the link that enables electrical connections between devices or systems and are essential components for a complete system. However, in actual use, the devices that secure plugs and sockets often shift due to manufacturing or mating errors. This can cause the connectors to not engage correctly or not engage properly, ultimately leading to damage to the connectors or a lack of reliable electrical contact.

[0003] Currently, board-to-board connectors connect two circuit boards via their respective soldered connectors to transmit current or signals. Currently, this type of connector requires that the positions of the two mating connectors be completely aligned to achieve signal connection between the two circuit boards. If there is a deviation in the relative positions of the two connectors, the connectors will not be able to connect properly, and the signal transmission efficiency within the current connector is relatively low.

The serial connector 4 includes a sheet body and a plurality of elastic arms 42 connected to the sheet body 41.

[0037] like Figure 1 and Figure 2 As shown, both ends of the insulating shell 1 are connected to an outer partition 12 a and an outer partition 12 b respectively, and the outer side of the insulating shell 1 is connected to an inner partition 13 .

[0038] Specifically, the plug-in floating connector includes: an insulating shell 1 and a plurality of plug-in conductive terminals 2; the insulating shell 11 is defined with mutually perpendicular plug-in directions S, length directions L and width directions W; wherein, the insulating shell 1 is recessed along the plug-in direction S to form a slot 11 from one side thereof; a plurality of plug-in conductive terminals 2 are arranged in two rows parallel to the length direction L, and the plug-in conductive terminals 2 in any row face the plug-in conductive terminals 2 in the width direction W respectively; wherein, any plug-in conductive terminal 2 is an integrally formed single-piece structure and includes a contact section 21, a fixed section 22 and a buffer section 23; the contact section 21 is inserted into the insulating shell 1, and a portion of the contact section 21 is located in the slot 11; the fixed section 22 is used to be fixed to an external component (not shown); the two ends of the buffer section 23 are respectively connected to the contact section 21 and the fixed section 22, and the long axis direction D23 of the buffer section is parallel to the fixed section 22.

[0039] like Figure 2 As shown, the buffer section 23 includes a first section 231 connected to the contact section 21 and a second section 232 connected to the fixed section 22, and one end of the two impedance matching sections 233 is connected to the first section 231, while the other end of the two impedance matching sections 233 is connected to the second section 232; the two impedance matching sections 233 of the buffer section 23 are arranged in a mirror-symmetrical manner relative to the buffer hole 234; the fixed section 22 and the buffer section 23 are exposed outside the insulating shell 1; and the two rows of plug-in conductive terminals 2 are arranged in a mirror-symmetrical manner relative to the slot 111.

[0040] In the present invention, the insulating housing 1 is formed with a plurality of through-holes 113 connected to the slot 111, and the plurality of plug-in conductive terminals 2 are respectively defined as a plurality of signal terminals and a plurality of ground terminals. That is, the plug-in conductive terminals 2 can be used as signal terminals or ground terminals, and the positions of the contact sections 21 correspond to the plurality of through-holes 113 respectively; two serial connectors 4 are connected to opposite sides of the insulating housing 1, and each serial connector 4 includes a plurality of elastic arms 42 arranged at intervals, and the plurality of elastic arms 42 of the two serial connectors 4 are respectively passed through the plurality of through-holes 113 and respectively abut against the contact sections 21.

[0041] In the present invention, by forming a buffer section 23 with a specific structural design (e.g., two impedance matching portions 233 surrounding a buffer hole 234, a numerical limitation of the first angle α1, and a relative relationship between the first angle α1 and the second angle α2), the plug-in conductive terminal 2 can simultaneously have a buffering (or shockproof) function and a signal conditioning function, thereby enabling the plug-in floating connector to be used for high-frequency (or high-speed) signal transmission through the plug-in conductive terminal 2.

[0042] The present invention can also be equipped with multiple power terminals 3 as required to meet different design requirements, and the plug-in floating connector can also be equipped with two serial connectors 4 electrically coupled to multiple ground terminals to effectively improve the common grounding effect of the plug-in floating connector.

[0043] The present invention provides an embodiment that can be plugged into an object connector (not shown) along a plugging direction S and used on a mobile object (e.g., a vehicle). When the embodiment and the object connector move relative to each other, the embodiment can stably maintain an electrical connection with the object connector.

[0044] like Figures 1 to 9 As shown, this embodiment includes an insulating shell 1, a plurality of plug-in conductive terminals 2 inserted into the above-mentioned insulating shell 1, a plurality of power terminals 3 inserted into the above-mentioned insulating shell 1 and located on one side of the plurality of plug-in conductive terminals 2, and two serial connectors 4 installed on the outer surface of the insulating shell 1; wherein, for the convenience of explaining this embodiment, the insulating shell 1 is defined with a length direction L and a width direction W perpendicular to the plug-in direction S and perpendicular to each other; that is, the length direction L is parallel to the long axis direction of the above-mentioned insulating shell 1.

[0045] In this embodiment, the plug-in floating connector is provided with a plurality of power terminals 3 and two serial connectors 4 , but is not limited thereto. For example, the plug-in floating connector may also be selectively provided with power terminals 3 and serial connectors 4 according to design requirements.

[0046] In this embodiment, the insulating housing 1 includes an elongated plug-in cavity 11, two outer partitions 12a and 12b connected to the two ends of the plug-in cavity 11, and an inner partition 13 connected to the plug-in cavity 11 and located between the two outer partitions 12a and 12b. The insulating housing 1 has a slot 111 and a power slot 112 recessed along one side thereof along the plug-in direction S, spaced apart from each other. The insulating housing 1 also has a plurality of through-holes 113 connected to the slot 111. The slot 111 is longer than the power slot 112 in the longitudinal direction L. The plurality of through-holes 113 are located on opposite sides of the slot 111 and arranged in two rows parallel to the longitudinal direction L. The two outer partitions 12a and 12b and the inner partition 13 are positioned corresponding to the lower half of the plug-in cavity 11 and perpendicular to the longitudinal direction L. The slot 111 corresponds to the area between the inner partition 13 and one of the outer partitions 12 a along the plug-in direction S, and the power slot 112 corresponds to the area between the inner partition 13 and the other of the outer partitions 12 b along the plug-in direction S.

[0047] In this embodiment, a plurality of plug-in conductive terminals 2 are mounted on the insulating housing 1, and a plurality of power terminals 3 are also mounted on the insulating housing 1 (e.g., in the portion of the plug-in cavity 11 corresponding to the power slot 112). An inner partition 13 separates the plurality of plug-in conductive terminals 2 from the plurality of power terminals 3. The plurality of plug-in conductive terminals 2 are arranged in two rows parallel to the length direction L, with the plug-in conductive terminals 2 in each row facing the plug-in conductive terminals 2 in the other row along the width direction W. The two rows of plug-in conductive terminals 2 are arranged in a mirror-symmetrical manner relative to the slot 111, but this is not limiting. For example, the two rows of plug-in conductive terminals 2 may also be arranged in a non-mirror-symmetrical manner.

[0048] In this embodiment, the plug-in conductive terminal 2 is a one-piece, integrally formed structure comprising a contact segment 21, a fixed segment 22, and a buffer segment 23 connected at both ends to the contact segment 21 and the fixed segment 22, respectively. The contact segment 21 is generally elongated and inserted into the insulating housing 1; the fixed segment 22 and the buffer segment 23 are exposed outside the insulating housing 1 and are generally located between the inner partition 13 and the outer partition 12a. The front portion 211 of the contact segment 21 is resilient and positioned within the slot 111 (i.e., the front portion 211 of the contact segment 21 is preferably not in contact with the insulating housing 1). The middle portion 212 of the contact segment 21 is secured to the plug cavity 11 to support the swinging motion of the front portion 211. The rear portion 213 of the contact segment 21 is bent from the bottom edge of the plug cavity 11 and is generally parallel to the width direction W.

[0049] In this embodiment, the fixing section 22 is generally elongated, and the long axis direction D22 of the fixing section 22 is generally parallel to the plug-in direction S, and is also generally parallel to the long axis direction D212 of the front section 211 and the middle section 212 of the contact section 21; wherein, the fixing section 22 (the tail end) is used to be fixed to an external component (such as a circuit board), and the tail end of the fixing section 22 in this embodiment is a structure suitable for surface mounting technology (SMT) welding, but is not limited thereto.

[0050] In this embodiment, the buffer section 23 extends obliquely from the rear portion 213 of the contact section 21 away from the plug cavity 11 at an angle greater than 90 degrees. The long axis D23 of the buffer section 23 forms a first angle α1 less than 90 degrees with the long axis D22 of the fixed section 22. The first angle α1 is preferably between 15 and 75 degrees, but is not limited thereto. In this embodiment, the buffer section 23 includes a first section 231 connected to (the rear portion 213 of) the contact section 21, a second section 232 connected to the fixed section 22, and two impedance matching sections 233. The two impedance matching sections 233 each surround a buffer hole 234, with one end of each impedance matching section 233 connected to the first section 231 and the other end of each impedance matching section 233 connected to the second section 232. Furthermore, in other embodiments not shown, the buffer segment 23 may include only two impedance matching portions 233, with one end of each impedance matching portion 233 connected to the contact segment 21 and the other end of each impedance matching portion 233 connected to the fixed segment 22. The two impedance matching portions 233 of the buffer segment 23 are arranged in mirror-symmetric fashion relative to the buffer hole 234. The buffer hole 234 may be elongated, with the long axis D234 of the buffer hole 234 and the long axis D22 of the fixed segment 22 forming a second angle α2 that is less than 90 degrees, and the difference between the second angle α2 and the first angle α1 is within 10 degrees. Preferably, the long axis D234 of the buffer hole 234 overlaps the long axis D23 of the buffer segment 23, that is, the second angle α2 is equal to the first angle α1, but this is not limited to the above.

[0051] In this embodiment, the buffering section 23 is configured to allow current to flow through, thereby generating a capacitive effect on the two impedance matching sections 233. That is, according to the formula: the square of the characteristic impedance multiplied by the capacitance value equals the inductance value (R2C=L), and the inductance value changes with the length of the plug-in conductive terminal 2. Therefore, the plug-in conductive terminal 2 can adjust (or reduce) the characteristic impedance in response to the length change of the plug-in conductive terminal 2 through the capacitive effect generated by the two impedance matching sections 233. The bottom edge of each plug-in conductive terminal 2 (e.g., the bottom edge of the fixing section 22) and the bottom edge of each power terminal 3 protrude beyond the bottom edge of the insulating housing 1. When the bottom edges of the plug-in conductive terminals 2 and the bottom edges of the power terminals 3 are fixed to an external object (e.g., a circuit board), the insulating housing 1 can move relative to the fixing sections 22 of the plug-in conductive terminals 2, thereby compressing the buffering sections 23 and providing a restoring force to the insulating housing 1.

[0052] In this embodiment, the plug-in conductive terminal 2 is formed with a buffer section 23 of a specific structural design (e.g., two impedance matching portions 233 surrounding the buffer hole 234 and the first angle α1 being less than 90 degrees) so that the plug-in conductive terminal 2 can simultaneously have a buffering (or shockproof) function and a signal conditioning function, thereby enabling the plug-in floating connector to be used for high-frequency (or high-speed) signal transmission through the plug-in conductive terminal 2.

[0053] In this embodiment, two serial connectors 4 are respectively installed on opposite sides of the above-mentioned insulating shell 1, and each serial connector 4 includes a sheet 41 and a plurality of elastic arms 42 extending from the long edge of the sheet 41 and arranged at intervals; wherein, each serial connector 4 is fixed to the outer surface of the plug-in cavity 11 of the above-mentioned insulating shell 1 through its sheet 41, and the plurality of elastic arms 42 of the two serial connectors 4 are respectively penetrated through the plurality of through-holes 113 and respectively abut against the contact section 21.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
