[0060] Please refer to Figures 1 to 3 . Figure 1 It is a three-dimensional schematic diagram of a connector 100 according to an embodiment of the present invention. Figure 2 for Figure 1 A three-dimensional schematic diagram of the connector 100 from another viewing angle. Figure 3 For along Figure 1 1 to 3, a connector 100 includes a housing 110, an insulating portion 120, at least one first probe 130, and a plurality of second probes 140. The insulating portion 120 is at least partially disposed in the housing 110, and the insulating portion 120 is, for example, plastic steel, but the present invention is not limited thereto. The first probe 130 passes through the insulating portion 120, and the first probe 130 has a first end 130a and a second end 130b opposite to each other, and the first end 130a and the second end 130b protrude from the insulating portion 120 respectively, and the first end 130a is located in the housing 110 and is configured to make a signal connection with a device to be tested (not shown), and the second end 130b is located outside the housing 110 and is configured to make a signal connection with a test equipment (not shown). The second probes 140 pass through the insulating portion 120, and each of the second probes 140 has a third end 140a and a fourth end 140b opposite to each other, and the third end 140a and the fourth end 140b protrude from the insulating portion 120 and are located outside the housing 110, wherein the third end 140a is configured to be electrically connected to the device to be tested, and the fourth end 140b is configured to be electrically connected to the test equipment. In practical applications, the first probe 130 is used to transmit high-speed signals, such as 5G signals, and the second probe 140 is used to transmit power.

[0061] Since the connector 100 can be connected between the device to be tested and the testing equipment through the first probe 130 and the second probe 140 , the use of wires can be avoided, thereby helping to reduce the cost of consumables.

[0062] In addition, since the insulating portion 120 is disposed in the shell 110, and the first probe 130 passes through the insulating portion 120 and the first end 130a of the first probe 130 is located in the shell 110, the shell 110 can provide a good shielding effect for the first probe 130, which helps to reduce the chance of the first probe 130 being interfered with when transmitting high-speed signals.

[0063] Furthermore, in order to improve the shielding effect of the housing 110 , a gold-plated layer may be disposed on the inner and outer surfaces of the housing 110 , and the thickness of the gold-plated layer may be in a range between 1 micron and 2 microns.

[0064] In addition, to improve the stability of the first probe 130 in transmitting high-speed signals, a gold-plated layer may be provided on the surface of the first probe 130, and the thickness of the gold-plated layer may range between 1 micron and 2 microns. Similarly, to improve the stability of the second probe 140 in transmitting power, a gold-plated layer may also be provided on the surface of the second probe 140, and the thickness of the gold-plated layer may range between 1 micron and 2 microns.

[0065] More specifically, in this embodiment, if Figures 1 to 3 As shown, the housing 110 includes a first sub-housing 111, a second sub-housing 112 and a plurality of positioning pins 113. The second sub-housing 112 is connected to the first sub-housing 111, and the positioning pins 113 are connected to a side of the first sub-housing 111 away from the second sub-housing 112, that is, the first sub-housing 111 is connected between the second sub-housing 112 and the positioning pins 113. For example, the first sub-housing 111, the second sub-housing 112 and the positioning pins 113 can be an integrally formed metal structure, that is, the housing 110 is milled from a single piece of metal material. However, please note that the shapes of the first sub-housing 111 and the second sub-housing 112 shown in the accompanying drawings of the present case, as well as the number and arrangement of the positioning pins 113, do not limit the present invention. In practical applications, the positioning pins 113 can be engaged with the plate of the test equipment to fix the connector 100 and the test equipment to each other. Furthermore, as Figure 3 As shown, the insulating portion 120 is at least partially disposed in the first sub-housing 111 , and the first end 130 a of the first probe 130 is located in the second sub-housing 112 .

[0066] Furthermore, in this embodiment, the insulating portion 120 includes a body 121, a first protruding portion 122, and a second protruding portion 123. Figure 3As shown, the body 121 of the insulating part 120 is located in the first sub-shell 111, and the second end 130b of the first probe 130 and the fourth end 140b of the second probe 140 both protrude from the body 121. The first protrusion 122 of the insulating part 120 is connected to the body 121 and is located in the second sub-shell 112 of the shell 110, and the first end 130a of the first probe 130 protrudes from the first protrusion 122. The second protrusion 123 of the insulating part 120 is connected to the body 121, and the second protrusion 123 is located outside the first sub-shell 111 of the shell 110 and is separated from the first protrusion 122, and the third end 140a of the second probe 140 protrudes from the second protrusion 123.

[0067] On the other hand, in this embodiment, if Figure 3 As shown, the first probe 130 includes a first contact portion 131, a first needle body 132 and a second needle body 133. The first contact portion 131 defines a first end 130a and has a first outer diameter D1. The first needle body 132 is exposed outside the first protrusion 122 of the insulating portion 120 and has a second outer diameter D2. The first outer diameter D1 of the first contact portion 131 is greater than the second outer diameter D2 of the first needle body 132. The first needle body 132 is connected between the first contact portion 131 and the second needle body 133. The second needle body 133 is located in the first protrusion 122 and the body 121 and protrudes from the body 121. The second needle body 133 defines a second end 130b.

[0068] Furthermore, in practical applications, the second needle body 133 has a third outer diameter D3, which is greater than the second outer diameter D2 of the first needle body 132 and smaller than the first outer diameter D1 of the first contact portion 131. According to actual conditions, the third outer diameter D3 of the second needle body 133 may also be equal to the first outer diameter D1 of the first contact portion 131.

[0069] Similarly, in this embodiment, if Figure 3 As shown, each of the second probes 140 includes a second contact portion 141, a third needle body 142, and a fourth needle body 143. The second contact portion 141 defines a third end 140a and has a fourth outer diameter D4. The third needle body 142 is exposed outside the second protruding portion 123 of the insulating portion 120 and has a fifth outer diameter D5, and the fourth outer diameter D4 of the second contact portion 141 is greater than the fifth outer diameter D5 of the third needle body 142. The third needle body 142 is connected between the second contact portion 141 and the fourth needle body 143, the fourth needle body 143 is located in the second protruding portion 123 and the body 121 and protrudes from the body 121, and the fourth needle body 143 defines a fourth end 140b.

[0070] Furthermore, in practical applications, the fourth needle body 143 has a sixth outer diameter D6, which is greater than the fifth outer diameter D5 of the third needle body 142 and less than the fourth outer diameter D4 of the second contact portion 141. According to actual conditions, the sixth outer diameter D6 of the fourth needle body 143 may also be equal to the fourth outer diameter D4 of the second contact portion 141.

[0071] Please refer to Figure 4 . Figure 4 for Figure 1 3-4, the first contact portion 131 of the first probe 130 has a first recessed surface 131S, and the first recessed surface 131S is located on a side of the first contact portion 131 away from the first needle body 132. The first recessed surface 131S is suitable for contacting the signal connection portion of the device under test so that the signal of the device under test is connected to the test equipment.

[0072] Similarly, Figures 3-4 As shown, the second contact portion 141 of the second probe 140 has a second recessed surface 141S, which is located on a side of the second contact portion 141 away from the third needle body 142. The second recessed surface 141S is suitable for contacting the electrical connection portion of the device under test to allow the device under test to be electrically connected to the test equipment.

[0073] It is worth noting that, since the first probe 130 contacts the device under test with the first recessed surface 131S of the first contact portion 131, and the second probe 140 contacts the device under test with the second recessed surface 141S of the second contact portion 141, when the connector 100 is connected to the device under test, the housing 110 of the connector 100 is fixed to the device under test, and the device under test will not touch the side surfaces of the first probe 130 and the second probe 140. Therefore, even if the device under test and the connector 100 are assembled and disassembled multiple times, the side surfaces of the first probe 130 and the second probe 140 will not generate friction with the device under test to form scratches, which also avoids the generation of tiny particles.

[0074] In practical applications, as shown in FIGS. 1 to 4 , the connector 100 further includes at least one first sleeve 150 and a plurality of second sleeves 160. The first sleeve 150 is sleeved outside the second needle body 133 of the first probe 130 to improve the stability of the first probe 130 in transmitting high-speed signals. The second sleeves 160 are respectively sleeved outside the fourth needle body 143 of the second probe 140 to improve the stability of the second probe 140 in transmitting power.

[0075] Furthermore, to further improve the stability of the first probe 130 in transmitting high-speed signals, a gold-plated layer may be provided on the inner and outer surfaces of the first sleeve 150, and the thickness of the gold-plated layer may range between 1 micron and 2 microns. Similarly, to further improve the stability of the second probe 140 in transmitting power, a gold-plated layer may also be provided on the inner and outer surfaces of the second sleeve 160, and the thickness of the gold-plated layer may range between 1 micron and 2 microns.

[0076] In summary, the technical solution disclosed in the above embodiments of the present invention has at least the following advantages:

[0077] (1) Since the insulating portion is disposed in the housing, and the first probe passes through the insulating portion and the first end of the first probe is located in the housing, the housing can provide a good shielding effect for the first probe, thereby helping to reduce the chance of the first probe being interfered with when transmitting high-speed signals.

[0078] (2) Since the connector can be connected between the device to be tested and the test equipment through the first probe and the second probe, the use of wires can be avoided, thereby helping to reduce the cost of consumables.

[0079] (3) Since the first probe contacts the device to be tested with the first concave surface of the first contact portion, and the second probe contacts the device to be tested with the second concave surface of the second contact portion, when the connector is connected to the device to be tested, the housing of the connector will be fixed to the device to be tested, and the device to be tested will not touch the side surfaces of the first probe and the second probe. Therefore, even if the device to be tested and the connector are assembled and disassembled multiple times, the side surfaces of the first probe and the second probe will not rub against the device to be tested to form scratches, which also avoids the generation of microparticles.

[0080] Although the present invention has been disclosed as above in the form of an implementation method, it is not intended to limit the present invention. Anyone skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of the attached patent application.
