Description

TECHNICAL FIELD

[0001] The present disclosure relates to an electrical connection assembly, and particularly to an electrical connection assembly with a bridge connector. BACKGROUND

[0002] To achieve electrical connection between different electronic devices, various forms of electrical connectors have existed. Electrical connectors can be distinguished by the location where they are arranged, such as line end connectors and board end connectors. The line end connectors are located at one end of a cable and are used to adaptively couple with the board end connectors, while the board end connectors are arranged on a circuit board. With the continuous progress and constant innovation of various electronic products, the performance of new electronic products has been greatly improved, and the types of electrical signals tend to be more diverse and require more bandwidth. Therefore, the demand for high-speed connectors is also increasing to meet high-speed and high-frequency connections.

[0003] However, in order to meet the large amount of data transmission, the transmission bandwidth of the electrical connector needs to be improved, and at the same time of improving the transmission bandwidth, the frequency of the transmitted electronic signal must be increased. When the height of the combined electrical connectors is higher, it means that the length of the transmitted signal terminal is also lengthened, and the use of high-frequency signals is prone to crosstalk phenomenon, thereby affecting the transmission of signals. In addition, for the setting environment of the electrical connector, the traditional two pairs of electrical connectors have a limit on the height of the connection. SUMMARY

[0004] A technical aspect of the present disclosure is an electrical connection assembly.

[0005] According to some embodiments of the present disclosure, an electrical connection assembly includes two electrical connectors and a bridge connector. The two electrical connectors each include a plurality of terminals and an insulating housing accommodating the terminals. The bridge connector is located between the two electrical connectors. The bridge connector includes an insulating body, a conductive plastic, a plurality of signal terminals, and a plurality of ground terminals. The conductive plastic is covered by the insulating body. The ground terminals and the signal terminals of the bridge connector are arranged in a spaced manner. The ground terminals of the bridge connector are in electrical contact with the conductive plastic.

[0006] In some embodiments, the conductive plastic is an I-shaped or a W-shaped.

[0007] In some embodiments, when the opposite sides of the insulating body are coupled by the two electrical connectors to surround, the ground terminals of the bridge connector are located between the conductive plastic and the terminals of the two electrical connectors.

[0008] In some embodiments, the conductive plastic has a main body portion and a plurality of finger portions protruding from the main body portion, and the ground terminals of the bridge connector are respectively located on the finger portions.

[0009] In some embodiments, the finger portions are symmetrically arranged along the opposite sides of the main body portion.

[0010] In some embodiments, each of the above-mentioned finger portions has a step difference between a side thereof distal to the body portion and the body portion.

[0011] In some embodiments, the length direction of the above-mentioned finger portions of the conductive plastic is the same as the length direction of the ground terminals of the bridge connector.

[0012] In some embodiments, the distance between two adjacent ones of the above-mentioned finger portions of the conductive plastic is greater than the distance between two adjacent ones of the signal terminals.

[0013] In some embodiments, each of the terminals of the above-mentioned two electrical connectors comprises a contact portion, a fixing portion and a soldering portion connected in sequence. The soldering portion extends from a surface distal to the bridge connector. When the opposite sides of the insulating body are respectively surrounded by the two electrical connectors coupled, the contact portion electrically contacts one of the ground terminals of the bridge connector.

[0014] In some embodiments, each of the above-mentioned two electrical connectors has a receiving groove. The insulating body of the bridge connector has two opposite protrusions configured to be respectively inserted into the two receiving grooves of the two electrical connectors, and the ground terminals of the bridge connector extend from one of the two protrusions to the other.

[0015] In some embodiments, the insulating body of the above-mentioned bridge connector has a blocking portion surrounding the two protrusions. When the two protrusions are configured to be respectively inserted into the two receiving grooves of the two electrical connectors, the opposite sides of the blocking portion respectively abut the two electrical connectors.

[0016] In some embodiments, the signal terminals of the above-mentioned bridge connector are separate from the conductive plastic.

[0017] In the above-mentioned embodiments of the present disclosure, since the bridge connector of the electrical connection assembly has the conductive plastic, the signal terminals and the ground terminals, and the ground terminals of the bridge connector electrically contact the conductive plastic, when the opposite sides of the insulating body of the electrical connection assembly are respectively surrounded by the two electrical connectors coupled, the ground terminals of the bridge connector can respectively electrically contact the terminals of the two electrical connectors. Through the above design, when coupled with the two electrical connectors, the bridge connector can make the terminals of the two electrical connectors conductive through the ground terminals and the conductive plastic of the bridge connector, avoiding the crosstalk problem between the signal differential pairs generated when the signal is transmitted at high speed, thus meeting the high-frequency signal transmission, being beneficial to the improvement of the transmission bandwidth and the increase of the electronic signal frequency, and being suitable for a large amount of data transmission requirements. In addition, the electrical connection assembly can change the docking height (e.g., increase) between the two electrical connectors of different devices by changing (e.g., increasing) the height of the bridge connector, which is not only beneficial to the flexibility of design but also can improve the transmission rate.

[0028] Figure 1 An exploded view of an electrical connection assembly 300 according to an embodiment of the present disclosure is shown. As shown, the electrical connection assembly 300 includes two electrical connectors 200 and a bridge connector 100. The bridge connector 100 is configured to couple the two electrical connectors 200. The electrical connectors 200 can be disposed on a circuit board as board-mount connectors, or connected with cables as cable-mount connectors. In some embodiments, the electrical connection assembly 300 can be applied to servers and workstations, but is not intended to limit the present disclosure. Each of the two electrical connectors 200 includes a plurality of terminals and an insulative housing 210 that houses the terminals. For example, the electrical connector 200 can include a plurality of signal terminals 220 and a plurality of ground terminals 230. The signal terminals 220 and the ground terminals 230 are disposed in receiving slots S of the insulative housing 210, and the ground terminals 230 and the signal terminals 220 are arranged in an alternating manner, for example, in parallel along the X-axis direction. In the present embodiment, any two adjacent signal terminals 220 are disposed between any two ground terminals 230, for example, in the order of a ground terminal 230, a signal terminal 220, a signal terminal 220, and a ground terminal 230. With such an arrangement, the two adjacent signal terminals 220 can be differential pair signal terminals.

[0029] When the two electrical connectors 200 and the bridge connector 100 of the electrical connection assembly 300 are combined, the bridge connector 100 is disposed between the two electrical connectors 200. In the present embodiment, the insulative housing 210 of the electrical connector 200 has a receiving slot S for the bridge connector 100 to be inserted. The insulative body 110 of the bridge connector 100 has two protruding portions 112a, 112b opposite to each other, and has a blocking portion 114 surrounding the two protruding portions 112a, 112b. For example, the two protruding portions 112a, 112b of the insulative body 110 extend upward and downward, respectively. The two protruding portions 112a, 112b are configured to be inserted into the two receiving slots S of the two electrical connectors 200, respectively. With the above design, when the two protruding portions 112a, 112b of the insulative body 110 of the bridge connector 100 are inserted into the two receiving slots S of the two electrical connectors 200, respectively, the two opposite sides (e.g., the top and bottom surfaces) of the blocking portion 114 can abut against the two insulative housings 210 of the two electrical connectors 200, respectively.

[0030] Figure 2 Draw Figure 1 A perspective view of the bridging connector 100 with the insulating body 110 omitted. See also... Figure 1 and Figure 2 The bridging connector 100 includes an insulating body 110, a plurality of signal terminals 120, a plurality of ground terminals 130, and conductive plastic 140. The conductive plastic 140 is covered by the insulating body 110. The ground terminals 130 and signal terminals 120 of the bridging connector 100 are arranged at intervals, for example, parallel to each other along the X-axis. In this embodiment, any two adjacent signal terminals 120 are located between two of the ground terminals 130, for example, arranged in the order of ground terminal 130, signal terminal 120, signal terminal 120, and ground terminal 130. With this configuration, two adjacent signal terminals 120 of the bridging connector 100 can be used to couple to the signal terminals 220 of the electrical connector 200 to transmit differential signals. Furthermore, the ground terminals 130 of the bridging connector 100 are in electrical contact with the conductive plastic 140, while the signal terminals 120 are separate from the conductive plastic 140 and are not conductive.

[0031] In this embodiment, the conductive plastic 140 can be H-shaped or T-shaped. The conductive plastic 140 has a main body 142 and a plurality of fingers 144 protruding from the main body 142. The grounding terminal 130 of the bridging connector 100 is located on these fingers 144 respectively. The length direction of the fingers 144 of the conductive plastic 140 is the same as the length direction of the grounding terminal 130, for example, both are in direction D.

[0032] In some implementations... Figure 2 The structure can be formed by compression molding or injection molding processes. Figure 1 The insulating body 110 positions the signal terminal 120 and the ground terminal 130. The ground terminal 130 and signal terminal 120 of the bridging connector 100 extend from one protrusion 112a to the other protrusion 112b of the insulating body 110. The insulating body 110 may be made of plastic, the signal terminal 120 and ground terminal 130 may be made of metal (e.g., copper), and the conductive plastic 140 may be made of plastic and conductive materials doped with the plastic (e.g., gold, silver, or copper). With this design, the resistance of the conductive plastic 140 is greater than the resistance of the ground terminal 130 but less than the resistance of the insulating body 110.

[0033] The following description will explain the state of the ground terminals 130 and 230 and the signal terminals 120 and 220 after the electrical connector 200 is coupled to the bridge connector 100.

[0034] Figure 3 Draw Figure 1 A perspective view of the electrical connector 200 of the electrical connection assembly 300 coupled with the bridge connector 100.Figure 4 FIG. 4 shows a cross-sectional view of the electrical connection assembly 300 along line 4-4. Also refer to Figure 3 FIG. 5 shows a cross-sectional view of the electrical connection assembly 300 along line 5-5. Also refer to Figure 3 FIG. 6 shows a cross-sectional view of the electrical connection assembly 300 along line 6-6. Also refer to Figure 4 In particular, since the bridge connector 100 of the electrical connection assembly 300 has the conductive plastic 140, the signal terminal 120 and the ground terminal 130, and the ground terminal 130 of the bridge connector 100 is in electrical contact with the conductive plastic 140, when the opposite sides of the insulating body 110 of the bridge connector 100 are respectively coupled by two electrical connectors 200, the ground terminal 130 of the bridge connector 100 can respectively electrically contact the ground terminals 230 of the two electrical connectors 200. Through the above design, when coupled with the two electrical connectors 200, the bridge connector 100 can make the ground terminals 230 of the two electrical connectors 200 conductive through the ground terminal 130 and the conductive plastic 140 of the bridge connector 100, avoiding the crosstalk problem between the signal differential pairs when the signal is transmitted at high speed, thus meeting the high-frequency signal transmission, being beneficial to the improvement of transmission bandwidth and the increase of electronic signal frequency, and being suitable for a large amount of data transmission requirements. In addition, the electrical connection assembly 300 can change the docking height (e.g., increase) between the two electrical connectors 200 of different devices by changing (e.g., increasing) the height of the bridge connector 100, which is not only beneficial to the flexibility of design but also can improve the transmission rate.

[0035] The ground terminal 230 of the electrical connector 200 includes a contact portion 232, a fixing portion 234 and a soldering portion 236 connected in sequence. The soldering portion 236 extends from the surface of the insulating shell 210 away from the bridge connector 100. When the opposite sides of the insulating body 110 of the bridge connector 100 are respectively coupled by two electrical connectors 200, the contact portion 232 of the ground terminal 230 of the electrical connector 200 is in electrical contact with the ground terminal 130 of the bridge connector 100. In this state, the ground terminal 130 of the bridge connector 100 is located between the finger portion 144 of the conductive plastic 140 (see also Figure 2 ) and the ground terminal 230 of the electrical connector 200. The fixing portion 234 of the ground terminal 230 of the electrical connector 200 can be positioned in the inner wall of the insulating shell 210, and the soldering portion 236 of the ground terminal 230 can be used to be soldered on the circuit board.

[0036] Figure 5 FIG. 4 shows a cross-sectional view of the electrical connection assembly 300 along line 4-4. Also refer to Figure 3 FIG. 5 shows a cross-sectional view of the electrical connection assembly 300 along line 5-5. Also refer to Figure 3 FIG. 6 shows a cross-sectional view of the electrical connection assembly 300 along line 6-6. Also refer to Figure 5The signal terminal 220 of the electrical connector 200 has a contact portion 222, a fixing portion 224, and a soldering portion 226 connected in sequence. When the insulating body 110 of the bridging connector 100 is coupled and surrounded by two electrical connectors 200 on opposite sides, the contact portion 222 of the signal terminal 220 of the electrical connector 200 electrically contacts the signal terminal 120 of the bridging connector 100. In this state, the signal terminal 120 of the bridging connector 100 is located between the insulating body 110 and the signal terminal 220 of the electrical connector 200. Furthermore, the fixing portion 224 of the signal terminal 220 of the electrical connector 200 can be positioned on the inner wall of the insulating housing 210, and the soldering portion 226 of the signal terminal 220 can be soldered onto a circuit board.

[0037] When the bridging connector 100 is inserted into the receiving slot S of the insulating housing 210 of the electrical connector 200 (see...) Figure 1 When the signal terminals 220 of the electrical connector 200 are electrically connected to the signal terminals 120 of the bridge connector 100 respectively, they can transmit signals. In this state, the signal terminals 120 of the two electrical connectors 200 located on the upper and lower sides of the bridge connector 100 at two corresponding positions can transmit signals through one of the signal terminals 120 of the bridge connector 100.

[0038] It should be understood that the component connections, materials, and functions already described will not be repeated, but will be stated in advance. In the following description, a more detailed configuration of the grounding terminal 130 and conductive plastic 140 of the bridging connector 100 will be explained.

See also... Figure 6 and Figure 7 The conductive plastic 140 has fingers 144 symmetrically arranged on opposite sides of the main body 142. There is a step difference d between the side of the fingers 144 away from the main body 142 and the main body 142. Through this design, the conductive plastic 140 can be H-shaped or T-shaped. The grounding terminal 130 on the fingers 144 can electrically contact the grounding terminal 230 of the electrical connector 200 (see also...). Figure 4 The signal terminal 120, which is separate from the conductive plastic 140, can electrically contact the signal terminal 220 of the electrical connector 200 (see also...). Figure 5 ).

[0040] In addition, the distance between adjacent two of the fingers 144 of the conductive plastic 140 is greater than the distance between adjacent two of the signal terminals 120. With such design, it can be ensured that the signal terminals 120 will not contact the fingers 144 of the conductive plastic 140 or the ground terminals 130 in the X-axis direction, causing signal abnormality and structural interference.
