Description

Technical Field

[0001] The invention relates to a connector, in particular to a connecting device. Background Art

[0002] Coaxial cable is a transmission line used to transmit low-loss and high-frequency signals. It is mostly used for telephone, network, cable TV signal cables, antenna connections, etc. Unlike other isolated cables, in order to operate effectively, the shape and size of coaxial cables and their connectors are limited, and most of them are currently achieved through dedicated circular connectors. In addition, in recent years, in response to the vigorous development of various miniaturized intelligent devices, the relevant industry has generally used the advantages of thin printed circuit boards and mature processes to form the main circuits in the device. Therefore, when coaxial cables have their transmission advantages and printed circuit boards are frequently used in today's industry, there is bound to be a need for coaxial cables to be interconnected with the circuits on the printed circuit boards. However, the existing standardized circular connectors dedicated to coaxial cables, because their appearance is roughly the same diameter as the wire of the coaxial cable, if they are directly set on the printed circuit board, it will affect the original intention of making the circuit thinner, and when the circular connector has its standardized shell, it is also difficult to integrate with the structure of the printed circuit board, so it cannot be an ideal solution for connecting coaxial cables and printed circuit boards.

[0028] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0029] See also Figure 1 , is a first embodiment of the connection device of the present invention, the first embodiment comprises an integration unit 1, and a connection unit 2 connected to the integration unit 1. In the first embodiment, the case of connecting to a driving board 9 made in the form of a printed circuit board is described.

[0030] See also Figure 1 and Figure 2The integrated unit 1 includes a package body 11 defining a setting space 101 having an opening 109 and a channel 102 communicating between the setting space 101 and the outside, a printed circuit module 12 arranged in the setting space 101, two coaxial cables 13 passing through the channel 102 and connected to the printed circuit module 12, a fixing member 14 passing through the package body 11 and the printed circuit module 12 and used to fix the printed circuit module 12, and two alignment pins 15 ( Figure 2 Only one of them can be seen due to the viewing angle). Specifically, the package body 11 is a shell for installing the printed circuit module 12 and the coaxial cable 13, so the setting space 101 is in accordance with the form of the printed circuit module 12. In order to facilitate connection, each coaxial cable 13 has a length at the end where the outer protective layer is stripped off, thereby exposing a part of the internal core wire. The channel 102 is in accordance with the coaxial cable 13, so that the end of the coaxial cable 13 with the exposed core wire is inserted into the channel 102 for a distance of preferably at least 3.7 mm, so that the core wire is extended to a position where it can be connected to the printed circuit module 12, and the coaxial cable 13 is prevented from falling off from the package body 11.

[0031] See also Figure 3 And cooperate Figure 2 The printed circuit module 12 has an insulating substrate 120, four first connecting members 121 ( Figure 3 Only one is visible due to the viewing angle), four second connecting members 122 formed on the insulating substrate 120 and facing the opening 109, and four third connecting members 123 ( Figure 3 The first connecting member 121 is shown in the figure, and a grounding member 125 formed on the insulating substrate 120. The grounding member 125 is located together with the second connecting member 122 on the side of the insulating substrate 120 opposite to the first connecting member 121, and can preferably be directly formed on the insulating substrate 120 by a printing process. Figure 3 As shown, the grounding member 125 defines two isolated areas S that are not connected to each other, and the four second connecting members 122 are respectively disposed in pairs in the isolated areas S, thereby forming a shield on a plane parallel to the insulating substrate 120 .

[0032] See also Figure 4, each coaxial cable 13 includes two signal lines 131 connected to the first connector 121, and a grounding line 132 connected to the grounding member 125. In the case where the package 11 is adapted to accommodate two coaxial cables 13, the four signal lines 131 of the coaxial cable 13 are respectively connected to the four first connectors 121. Then, through the third connector 123, the signal transmitted by the coaxial cable 13 can be conducted from the first connector 121 to the third connector 123, and then transmitted to the second connector 122. In addition, one of the grounding lines 132 in the coaxial cable 13 must be connected to the grounding member 125 to achieve a grounding effect. Therefore, in the first embodiment, the grounding member 125 has an extension 129 that penetrates the insulating substrate 120 and corresponds to the position of the grounding line 132, so that at least one of the grounding lines 132 can be connected to the grounding member 125.

[0033] Continue reading Figure 4 And cooperate Figure 2 The conductive unit 2 includes a shell 21 surrounding and defining a mounting groove 210, and a conductive module 22 installed in the mounting groove 210 and connected to the second connecting member 122 of the printed circuit module 12. The conductive module 22 has a plurality of insulating partitions 221, and a plurality of transmission members 222 disposed between adjacent insulating partitions 221 and spaced from each other. Specifically, the transmission member 222 between two adjacent insulating partitions 221 can be formed on a single-layer structure through a semiconductor process. In response to the form of the second connecting member 122 and the grounding member 125, the transmission member 222 can form a contact point that contacts the second connecting member 122 and the grounding member 125. After the transmission member 222 is connected to the printed circuit module 12, a plurality of contacts corresponding to the driving board 9 will also be formed on the side of the transmission member 222 opposite to the integration unit 1, thereby preparing to contact the driving board 9 to achieve connection.

[0034] The fixing member 14 is provided through the package body 11 and the printed circuit module 12, and is used to fix the printed circuit module 12, so that the printed circuit module 12 and the coaxial cable 13 are in a desired relative position. Figure 5 ) is simultaneously provided through the packaging body 11, the printed circuit module 12, and the shell 21 of the conductive unit 2, thereby fixing the relative position between the printed circuit module 12 and the conductive module 22, ensuring that the printed circuit module 12 and the conductive module 22 are securely connected and stably transmit signals.

[0035] See also Figure 5 And cooperate Figure 2 and Figure 4 In the first embodiment, the coaxial cable 13 is first connected to the printed circuit module 12 through the integration unit 1, and then the printed circuit module 12 is further connected to the conductive unit 2 through the opening 109. The conductive unit 2 is advantageously used to give full play to its characteristic of easy design of diversified contacts through the conductive module 22, thereby directly contacting and connecting the conductive module 22 with the printed circuit board to be connected (the driving board 9 in the first embodiment) in response to various contact forms formed on the printed circuit board, thereby meeting the need for the coaxial cable 13 to be connected to the printed circuit board.

[0036] See also Figures 6 to 8 , which is a second embodiment of the connection device of the present invention. The difference between the second embodiment and the first embodiment is that the printed circuit module 12 of the integrated unit 1 has a first insulating plate 120a, a second insulating plate 120b spaced apart from the first insulating plate 120a, four first connecting members 121 formed on the first insulating plate 120a and facing the channel 102, four second connecting members 122 formed on the second insulating plate 120b and facing the opening 109, and four third connecting members 123 respectively connected between the first connecting member 121 and the second connecting member 122 ( Figure 7 The first and second connecting members 121 and 122 are respectively formed on the first and second insulating plates 120a and 120b on opposite sides of the first and second insulating plates 120a and 120b away from the grounding member 125, and the grounding point 124 is formed on the side of the second insulating plate 120b away from the grounding member 125, that is, it is located on the same plane as the second connecting member 122.

[0037] In the second embodiment, the areas of the first insulating plate 120a and the second insulating plate 120b are different. The second insulating plate 120b is designed to be shorter than the first insulating plate 120a along a length parallel to the coaxial cable 13, so that a portion of the grounding member 125 attached to the first insulating plate 120a can be directly exposed to the outside. The grounding wire 132 of the coaxial cable 13 can directly contact the exposed portion of the grounding member 125, thereby connecting the grounding wire 132 to the grounding member 125.

[0038] In order to achieve a shielding effect on the transmitted signal through the grounding member 125, the grounding member 125 has a plurality of through holes H ( Figure 7 Only one is shown in the figure, by allowing the third connecting member 123 connected between the first connecting member 121 and the second connecting member 122 to pass through the through hole H respectively, the transmitted signal can be shielded on the same plane as the grounding member 125, thereby optimizing the signal transmission quality transmitted from the coaxial cable 13 to the conductive unit 2.

[0039] The signal transmitted by the coaxial cable 13 is transmitted to the second connector 122 through the first connector 121. When the conductive unit 2 can be properly connected to the printed circuit module 12 through the second connector 122 and the grounding contact 124, the signal of the coaxial cable 13 can be surely transmitted to the printed circuit board as long as the conductive module 22 and the contact of the printed circuit board to be connected correspond to each other. Therefore, compared with the first embodiment, in addition to forming the first connector 121 directly on the first insulating plate 120a and properly connecting the grounding wire 132 of the coaxial cable 13 through the grounding member 125, the second embodiment substantially achieves the same effect of making the coaxial cable 13 and the printed circuit board simply and stably connected as in the first embodiment.
