Fig. 1-5 are various schematic views of an integrated connector in an embodiment. The integrated connector 10 in one embodiment includes a main body 100 and a signal transmission assembly 200. Wherein the main body 100 is provided with at least two accommodating chambers 110. At least two receiving chambers 110 are provided independently of each other. The number of the signal transmission assemblies 200 is the same as and corresponds to one with the number of the receiving chambers 110 formed on the main body 100. Each signal transmission assembly 200 is independently fixed in the corresponding receiving chamber 110 for independent transmission of signals.

Each signal transmission assembly 200 includes an inner conductor 210, an insulator 220, and a shield 230, see fig. 4 and 5. The insulator 220 is sleeved outside the inner conductor 210, and the shield 230 is sleeved outside the insulator 220. The inner conductor 210 serves as a signal transmission body, the shield 230 serves to prevent interference of external signals to the inner conductor 210, and the insulator 220 serves to secure insulation of the inner conductor 210. One end 202 of each signal transmission assembly 200 is configured to interface with a different signal source device. The other end 204 of each signal transmission assembly 200 is used for being connected with a circuit board of the same target device, so that the electrical connection between different signal source devices and the same target device can be realized through the integrated connector.

In the integrated connector, at least two accommodating cavities 110 independent of each other are formed in the main body 100, and the signal transmission assembly 200 is fixed in each accommodating cavity 110. The signal transmission components 200 are independent of each other, so as to perform independent transmission of signals. One end 202 of each signal transmission component 200 is electrically connected with different signal sources, and the other end 204 is electrically connected with the circuit board of the same target device, so that the different signal sources can simultaneously and independently transmit signals into the target device through the integrated connector, and the space required by product installation is greatly reduced. In addition, the inner conductor 210 of the signal transmission assembly 200 is sleeved with the insulating layer 220, and the insulating layer 220 is sleeved with the shielding layer 230, so that signal transmission between adjacent signal transmission assemblies can be ensured not to be interfered.

Fig. 6a is an enlarged view of the inner conductor 210 of fig. 5, and the inner conductor 210 may be manufactured by a conventional stamping process, which may reduce the cost of the product. Fig. 6b is an enlarged schematic view of the insulating layer 220 in fig. 5. The insulating layer 220 is formed by injection molding, which can also reduce the cost of the product. The shield 230 may be formed from a metallic conductor material. In one embodiment, shield 230 includes a shield body 232 and a connection leg 234, as shown in fig. 6 c. Shield body 232 is connected to connection leg 234. The shielding body 232 and the connecting pins 234 may be integrally formed, or may be connected by a process such as welding after being separately formed. The shielding body 232 is sleeved on the outer surface of the insulator 220 by adopting a closed structure, so that the single weight and the cost of the product can be reduced. The connection pins 234 are used for soldering to a circuit board of a target device to make electrical connection with the circuit board (PCB) of the target device. In the present embodiment, the connection pins 234 are provided with four. Four connection pins 234 are provided at one end of the shielding body 232 at equal intervals. In other embodiments, the number of connection pins 234 may be set as desired.

In one embodiment, the integrated connector further includes stiffener 300. The reinforcement member 300 is fixed to the main body 100 for electrically connecting with a circuit board of a target device to reinforce the connection between the circuit board and the integrated connector. In one embodiment, the reinforcement 300 may also be used as a ground contact. In the present embodiment, the reinforcing members 300 are provided in 2 numbers, respectively provided at the upper and bottom portions of the respective receiving chambers 110. Correspondingly, the shielding body 232 is further provided with a stop portion 236. The stop portion 236 is disposed on a surface of the shielding body 232 connected to the insulator 220 and abuts against the body 100, so as to prevent the signal transmission assembly 200 from sliding off the body 100.

In one embodiment, the body 100 is further provided with a guide post 120. The guide post 120 is used for guiding the integrated connector to be in butt joint with the circuit board of the target device, so that accurate butt joint between the integrated connector and the target device is realized. The number of the guide posts 120 may be set as desired.

Referring to fig. 1 and 2, in the present embodiment, the number of signal transmission assemblies 200 and receiving chambers 110 is four. The four signal transmission components 200 are used to transmit at least one of a radio frequency signal and a differential signal. For example, four signal transmission assemblies 200 may be used to transmit radio frequency signals in the arrangement shown in fig. 7 a. The four signal transmission assemblies 200 may also transmit radio frequency signals using only three or two of them, as shown in fig. 7b and 7c, respectively. Four signal transmission assemblies 200 may also be used for high speed signal transmission in the arrangement shown in fig. 8a and 8 b. In other embodiments, the number of signal transmission assemblies 200 and receiving chambers 110 may be set according to the number of signal source devices to which the target device needs to be connected, to four, five, etc. In an embodiment, the number of signal transmission assemblies 200 may also be set to an even multiple, so as to ensure that the integrated connector can implement transmission of differential signals.

An embodiment of the present invention further provides a terminal device, where the terminal device is used as a target device for the plurality of signal source devices. The terminal device includes the integrated connector of any of the previous embodiments, further including a circuit board connected to the integrated connector. The circuit board includes a substrate 910 and a via unit 920, as shown in fig. 9. The via unit 920 is disposed on the substrate 910. The number of via units 920 is the same as the number of signal transmission components in the integrated connector and is arranged in a one-to-one correspondence. Each via unit 920 includes an inner conductor solder via 922, a shield ground via 924, and an additional via 926. Wherein the shield ground vias 924 and the additional vias 926 are each disposed about the inner conductor solder vias 922, and the additional vias 926 are disposed between adjacent shield ground vias 924. Specifically, the inner conductor welding via 924 is used for welding with an inner conductor of a signal transmission component on a corresponding integrated connector, so as to realize electrical connection between the inner conductor and the circuit board. The shields on the signal transmission assembly are grounded through shield ground vias 924. The additional vias 926 are used to enhance isolation between signals, thereby ensuring that signals between the various signal transmission components are stably and independently transmitted. It will be appreciated that other electronic circuitry for performing the functions of the target device may also be provided on the substrate 910.

In one embodiment, the number of shield-to-ground vias 924 in each via unit 920 is three and the number of additional vias 926 is four. The three shield ground vias 924 are distributed 180 degrees in a fan shape centered on the inner conductor solder vias 922. Optionally, three shield ground vias 924 are disposed perpendicular to each other. At least two of the four accessory vias 926 are disposed adjacent and between adjacent two of the outer conductor ground vias 924 to enhance signal isolation.

In one embodiment, the circuit board further includes a reinforcement pin solder via 930. The stiffener on the integrated connector may be connected to the circuit board through the stiffener pin solder vias 930, thereby strengthening the electrical connection between the integrated connector and the circuit board.

In one embodiment, the circuit board further includes a guide post guide via 940. The guide posts on the integrated connector body are connected to the circuit board through guide post guide vias 940. And further, the precise butt joint of the integrated connector and the circuit board is realized through the connection of the guide post and the guide post guide through hole 940.

The circuit board may be connected in combination as shown in fig. 10a and 10b when the signals transmitted by the integrated connector are one to two pairs of differential signals diff1 and diff 2; when the input signals are one to four paths of radio frequency signals RF 1-RF 4, the connection combination is shown in FIG. 10 c; a pair of differential and one or two rf signals combined is shown in fig. 10 d. When the signals transmitted by the integrated connector are one to two pairs of differential signals, a ground network may be formed in common, as shown in fig. 11a and 11b; when the input signals are one-way to four-way differential signals, the radio frequency signals with the same property can share one ground, the radio frequency signals with different properties need to be separated from the ground of the respective signals, and the ground is split and combined according to actual needs, as shown in fig. 11 c. When the input signals are a pair of differential signals and one or two paths of radio frequency signals, the radio frequency signals with the same property can share one ground, the radio frequency signals with different properties need to be divided into the respective grounds, the grounds are split and combined according to actual needs, and the differential signals share the same ground to form a ground network, as shown in fig. 11 d. The blocks in fig. 11a to 11d represent ground.

By arranging the circuit board correspondingly connected with the integrated connector, the integrated connector can output signals of a plurality of different signal source devices to the circuit board positioned in the target device at the same time, so that the space required by product installation is greatly reduced. For example, when the signal acquisition system has a plurality of signal acquisition terminals, the plurality of signal acquisition terminals need to output the acquired signals to a terminal device (i.e., a target device). The integrated connector can be used for realizing connection between a plurality of signal acquisition terminals and terminal equipment, so that the plurality of signal acquisition terminals can transmit signals to the terminal equipment simultaneously, the convenience of operation can be improved, and the complexity of products is reduced.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
