Description

[Technical Field]

[0001] The present invention relates to an electrical connection device, and more particularly to an electrical connection device that can be modularized. [Background technology]

[0002] All systems and devices related to electrical signals must take into consideration signal transmission characteristics, such as frequency, speed, distance, etc. During system development, connection devices that match the signal characteristics must be selected according to the application. The transmission mode can be, for example, single-ended transmission or differential transmission.

[0003] In single-ended transmission, a signal has one signal end and one reference end, and the reference end is generally a ground end, so the signal is transmitted only through a single signal end. Single-ended transmission has the advantages of low cost and is less affected by space constraints in the application environment, but has the disadvantage of being easily interfered with.

[0004] Unlike single-ended transmission, which has one signal end and one reference end, differential transmission uses two signal lines to transmit signals, with the two signals having the same amplitude but opposite phase. Its advantages include high interference resistance, effective electromagnetic interference suppression, and precise timing positioning. However, the use of differential signal line pairs has the disadvantages of being expensive and requiring a large amount of space on the terminal circuit board.

[0005] As described above, single-ended and differential signal transmission modes each have their advantages and disadvantages, and single-ended and / or differential signal transmission can be selected depending on the application during system development. In particular, since different signal transmission modes must be selected depending on the application in test equipment, it is important to repeatedly test various signal transmission modes and / or wire materials during the testing stage.

[0006] Currently, the media used for signal transmission are connected via electrical connection devices using cables. These electrical connection devices generally have fixed specifications tailored to specific requirements, and some of their components cannot be changed to meet testing requirements. Furthermore, even in electronic products or system devices used for purposes other than testing, if some components of the electrical connection device connected to the cable are damaged, the entire device must be replaced; repairs cannot be made by simply replacing the components.

[0007] As mentioned above, existing electrical connection devices have fixed specifications and cannot meet the diverse requirements that arise during testing, and cannot be repaired if components are damaged during normal use. Therefore, further investigation was required to find a feasible solution. Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention has been made in view of the above-mentioned problems, and aims to provide a modularized electrical connection device, and by modularizing its components, it is possible to replace some of the components according to the requirements of testing or repair. [Means for solving the problem]

[0009] The main technical means for achieving the above object is that the modularized electrical connection device includes a connector, the connector including a hollow outer shell having a mounting groove penetrating in the front-rear direction, and a cable module mainly having a plurality of cable terminals detachably mounted on a fixing seat, the fixing seat having a shape corresponding to the mounting groove of the outer shell and detachably mounted in the mounting groove of the outer shell, the fixing seat having a plurality of terminal holes, each cable terminal having a terminal head and a coaxial cable, the terminal head having a connecting end and a tangential end, the connecting end being inserted into the terminal hole of the fixing seat, and the tangential end being connected to the coaxial cable. [Effects of the Invention]

[0010] The present invention utilizes the modular design described above to allow the main components of the connector to be replaced according to needs, including the outer shell, cable module, and the fixing base and cable terminal that make up the cable module, among which the cable terminal can be further replaced with coaxial cables of different resistances and lengths according to the requirements of the terminal in use, thereby meeting the requirements of actual use. The modular design is not only applicable to test equipment with different performance requirements, but also to general electronic products and systems. When the electrical connection device itself is damaged or the performance requirements change, the requirements can be met by simply replacing some components. [Brief explanation of the drawings]

[0012] The present invention provides a modularized electrical connection device, the main component of which is a connector, the connector having a cable module removably disposed in a mounting groove of an outer shell, the cable module having a plurality of wire terminals removably mounted in a fixing seat, the fixing seat having a shape corresponding to the mounting groove of the outer shell, removably mounted in the mounting groove of the outer shell, and a plurality of terminal holes, each cable terminal having a terminal head and a coaxial cable, the terminal head having a connecting end and a tangential end, the connecting end being inserted into the terminal hole of the fixing seat, and the tangential end being connected to the coaxial cable.

[0013] The connector can be applied to a female connector and / or a male connector. First, Fig. 1 discloses a female connector F and a male connector M that can be connected to each other, and a preferred embodiment of the female connector F includes a female-end housing 10 and a female-end cable module 20, as shown in Fig. 2. The female-end housing 10 in this embodiment is a hollow rectangular frame that is mainly composed of a top, a bottom, and two side sections and penetrates in the front-to-rear direction. An annular frame 11 is provided inside the female-end housing 10, dividing the interior of the female-end housing 10 into an inside and an outside. A mounting groove 12 for mounting the female-end cable module 20 is formed on the inside, and a connection groove 13 for connecting to the male connector M is formed on the outside.

[0014] In this embodiment, the inner walls of the two sides of the female-end housing 10 are respectively formed with wedge blocks 14 that protrude from the mounting groove 12, thereby further fixing the female-end cable module 20 that is mounted in the mounting groove 12. Furthermore, the outer surfaces of the two sides of the female-end housing 10 are respectively formed with coupling seats 15, and fixing holes are formed in the coupling seats 15, so that the female-end housing 10 can be fixed to a circuit board or other carrier.

[0015] Furthermore, to facilitate easier connection between the female connector F and the male connector M, alignment pillars 16 are formed on each of the two sides of the female end housing 10, extending in the connection direction, and the ends of the alignment pillars 16 are tapered.

[0016] In addition, in order to securely fix the female end cable module 20 in the mounting groove 12 of the female end housing 10, one or more wedge holes 17 are formed on the top and bottom of the female end housing 10, and wedge posts 18 are provided in each of the wedge holes 17. The wedge posts 18 are inserted into the mounting groove 12 to secure the female end cable module 20 in the mounting groove 12.

[0017] 2 and 3, the female-end cable module 20 includes a female-end fixing seat 21 and a plurality of female-end cable terminals 22, and the plurality of female-end cable terminals 22 are provided on the female-end fixing seat 21. The female-end fixing seat 21 corresponds in shape to the mounting groove 12 of the female-end housing 10, and is removably attached to the mounting groove 12 of the female-end housing 10.

[0018] In this embodiment, the female end fixing seat 21 is constructed by combining a front seat 211 and a rear seat 212, of which the front seat 211 has a plurality of terminal holes 213 formed therein, and the rear seat 212 has a plurality of wire holes 214 formed therein, each wire hole 214 corresponding to the terminal hole 213 of the front seat 211, and the front seat 211 and the rear seat 212 use their respective terminal holes 213 and wire holes 214 to fix each female end cable terminal 22.

[0019] Each female end cable terminal 22 includes a first terminal head 221 and a coaxial cable 222. The first terminal head 221 has a connecting end and a tangential end. The connecting end is inserted into the terminal hole 213 of the front seat 211, and the tangential end is joined to the coaxial cable 222. The coaxial cable 222 is pulled out from the wire hole 214 of the rear seat 212.

[0020] In this embodiment, wedge grooves 215, 216 are formed on both side edges of the front seat 211 and the rear seat 212, respectively, and these wedge grooves 215, 216 correspond to the wedge blocks 14 in the female end housing 10. When the female end fixing seat 21 is attached to the female end housing 10, these wedge blocks 14 fit into the wedge grooves 215, 216, strengthening the fixation of the female end fixing seat 21 to the female end housing 10. In addition, one or more recesses 218 are formed on the upper and lower surfaces of the rear seat 212, respectively, and these recesses 218 correspond to the wedge holes 17 of the female end housing 10, allowing the insertion of wedge posts 18, thereby enabling even stronger fixation.

[0021] The coaxial cable 222 can be selected with different resistance characteristics and lengths depending on the application and actual needs.

[0022] 4 shows the layout of each female-end cable terminal 22. This layout can be changed depending on the signal transmission method. In this embodiment, each female-end cable terminal 22 is divided into an upper and lower section, and each section includes a differential pair terminal group and a shunt terminal group. The differential pair terminal group includes one or more single-ended or differential pair terminals and one or more ground terminals, which are arranged alternately in the horizontal direction.

[0023] With this configuration, since the characteristics differ depending on the signal transmission method adopted, the layout of each female end cable terminal 22 can be adjusted according to the differences in characteristics, and this layout is realized by changing the positions of the terminal hole 213 in the front seat 211 and the wire hole in the rear seat 212.

[0024] 1 and 5 show a specific embodiment of a male connector M of the present invention. The male connector M includes a male-end housing 30 and a male-end cable module 40. In this embodiment, the male-end housing 30 is a hollow rectangular frame that is mainly composed of a top, a bottom, and two side sections and penetrates in the front-to-rear direction. One end of the male-end housing 30 in the connection direction is formed with an annular frame 31, and an attachment groove 32 is formed inside the frame 31, allowing the male-end cable module 40 to be attached.

[0025] Furthermore, alignment grooves 33 are formed on the outer surfaces of the two sides of the male end housing 30, and these alignment grooves 33 correspond to alignment posts 16 on the two sides of the female end housing 10, making it easier to insert the male end housing 30 into the connecting groove 13 of the female end housing 10 by guiding it with the alignment grooves 33.

[0026] In addition, one or more wedge holes 34 are formed at the top and bottom of the male end housing 30, and wedge posts 35 are provided in the wedge holes 34. The wedge posts 35 are inserted into the mounting grooves 32 to fix the male end cable module 40 provided in the mounting grooves 32.

[0027] The male end cable module 40 includes a male end fixing base 41 and a plurality of male end cable terminals 42, with the male end fixing base 41 provided with the plurality of male end cable terminals 42. The male end fixing base 41 corresponds in shape to the mounting groove 32 of the male end housing 30 and is detachably mounted in the mounting groove 32 of the male end housing 30. In this embodiment, the male end fixing base 41 is formed by combining a front base 411 and a rear base 412, with a plurality of terminal holes 413 formed in the front base 411 and a plurality of wire holes 414 formed in the rear base 412, each corresponding to the terminal hole 413 of the front base 411, and the front base 411 and rear base 412 using their respective terminal holes 413 and wire holes 414 to fix the male end cable terminals 42.

[0028] Each male end cable terminal 42 includes a second terminal head 421 and a coaxial cable 422, and the second terminal head 421 has a connecting end and a tangential end, the connecting end being inserted into the terminal hole 413 of the front seat 411, and the tangential end being joined to the coaxial cable 422, which is pulled out from the wire hole 414 of the rear seat 412 (see Figure 6).

[0029] In addition, one or more recesses 416 are formed on the upper and lower surfaces of the back seat 412, respectively, and these recesses 416 correspond to the wedge holes 34 of the male end housing 30, allowing the wedge posts 35 to be inserted, thereby enabling even stronger fixation.

[0030] As with the female connector F, the layout of the male cable terminals 42 can be changed depending on the signal transmission method. In this embodiment, each male cable terminal 42 corresponds to a female cable terminal 22 and is divided into an upper and lower section. Each section includes a differential pair terminal group and a shunt terminal group. The differential pair terminal group includes one or more single-ended or differential pair terminals and one or more ground terminals, which are arranged alternately in the horizontal direction.

[0031] 5, in order to easily secure the male connector M, a locking outer shell 50 is further provided on the male connector M, the locking outer shell 50 being a hollow rectangular frame whose internal shape and size correspond to the exterior of the male-end housing 30, so that it is attached to the male-end housing 30. In addition, in order to more firmly engage the male-end housing 30 and the locking outer shell 50, an engagement mass 36 is formed on the rear side of the top surface of the male-end housing 30, and a complementary engagement groove 51 is formed in the locking outer shell 50 at a position corresponding to the engagement mass 36, enabling them to engage with each other.

[0032] The locking shell 50 has one or more locking seats 52 formed on each side thereof, and the locking seats 52 have locking holes formed therein, so that the locking shell 50 can be fixed to another carrier using screws or other locking members.

[0033] From the above description, it is possible to grasp specific embodiments of the female connector F and male connector M of the present invention. Fig. 7 shows the external appearance after the female connector F and male connector M have been connected, and Fig. 8 shows the state in which the male-end housing 30 of the male connector M has been inserted into the connecting groove 13 of the female-end housing 10 by matching the shape of the male-end housing 30 with the connecting groove 13 of the female-end housing 10, in which case the connecting end of the second terminal head 421 of the male-end cable terminal 42 in the male-end housing 30 is electrically connected to the first terminal head 221 of the female-end cable terminal 22 in the female-end housing 10.

[0034] In the present invention, a coaxial cable is directly used as a signal transmission medium in an electrical connection device, and the coaxial cable can be connected to a terminal by soldering the other end of the coaxial cable directly to a printed circuit board or by connecting via a pogo pin provided on the terminal. Taking female connector F as an example, as shown in Figure 9, the upper and lower female end cable terminals 22 connect a coaxial cable 222 to the terminal via pogo pins 60, respectively.

[0035] The modular design allows all of the main components of the female connector F and male connector M to be separated and detached. This means that if any component is damaged or needs to be changed to meet specific requirements, they can be replaced as needed. For example, the female-end cable module 20 and male-end cable module 40, which are the main transmission signal media, as well as the female-end fixing base 21, female-end cable terminal 22, male-end fixing base 41, and male-end cable terminal 42, and even the terminal heads and coaxial cables that make up the female-end cable terminal 22 and male-end cable terminal 42, can all be individually replaced according to repair or specific requirements.
