DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the purpose, technical scheme and advantages of the present disclosure more clear, the following is a detailed explanation of the present disclosure, combined with specific embodiments and referring to the attached drawings.

[0021] However, it should be understood that these descriptions are only illustrative and not intended to limit the scope of the present disclosure. In the following detailed description, for ease of interpretation, many specific details are elaborated to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is evident that one or more embodiments may also be implemented without these specific details. In addition, in the following explanation, the description of the well-known technology is omitted to avoid unnecessary confusion with the concept of the present disclosure.

[0022] The terms used here are only for describing specific embodiments and are not intended to limit the present disclosure. The term comprising used here indicates the existence of features, steps and operations, but does not exclude the existence or addition of one or more other features.

[0023] In the case of using expressions such as at least one of A, B, and C, etc. or the like, it should generally be interpreted in accordance with the meaning of the expressions that those skilled in the art usually understand (for example, a system with at least one of A, B, and C should comprise but not be limited to a system with only A, a system with only B, a system with only C, a system with A and B, a system with A and C, a system with B and C, and/or a system with A, B, C, etc.).

[0024] All terms used here (comprising technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used here should be interpreted as having a meaning consistent with the context of this specification, and should not be interpreted in an idealized or overly rigid manner.

[0025] Referring to FIGS. 1-8, a connector 1000 according to an embodiment of the present disclosure is shown. The connector 1000 comprises: a first fastener 100 and a housing 200 made of metal. The first fastener 100 is provided on the housing 200 to secure the wire (see FIG. 9, i.e. the wire connected to a bus 600) between the housing 200 and the first fastener 100.

[0026] The housing 200 comprises two opposite side walls 210 and six fingers 220 extending from ends 211 of the side walls 210 towards a circuit board 2000, wherein, each of the side walls 210 is provided with three fingers 220 extending from its end 211. The circuit board 2000 is provided with a connecting area 2100 and six through holes 2200 provided in the connecting area (see FIG. 2). Each of the side walls 210 is provided with at least one shoulder 212, which is configured for withstanding an external force applied so as to crimp the six fingers 220 to the corresponding through holes 2200 of the circuit board 2000 respectively, so that each of the fingers 220 passes through the corresponding one of the through holes 2200 and is exposed from the through hole 2200 (see FIGS. 3-5). Therefore, the wire is electrically connected to a circuit on the circuit board 2000 through the fingers 220 of the housing 200 and the through holes 2200 where are inserted by the fingers 220.

[0027] A height H (see FIG. 2) from the shoulder 212 to the end 211 (more specifically, where the three fingers 220 and the side wall 210 are connected to each other) of the side wall 210 is selected so as to ensure that the housing 200 does not deform during the crimping process, greatly improving a reliability of the connector 1000.

[0028] More specifically, the housing 200 further comprises a top wall 230 connected between the two opposite side walls 210. The arrangement of shoulder 212 avoids the external force being applied to the top wall 230 of the housing 200, greatly reducing a height from a part of the housing 200 which is subject to the external force to the circuit board 2000, effectively reducing or even eliminating a risk of deformation of the housing 200 and damage to the connector 1000 due to the external force applied to the housing 200 being excessive during the process of crimping the fingers 220 into the through holes 2200 of the circuit board 2000. According to an expected magnitude of the external force, the height H from the shoulder 212 to the end 211 of the side wall 210 may be adjusted. For example, when the applied external force is larger, a magnitude of the height H may be set to be smaller, and when the applied external force is smaller, the magnitude of the height H may be set to be larger, greatly expanding an applicability of the connector 1000.

[0029] The first fastener 100 is provided on the top wall 230 and configured to extend through the top wall 230.

[0030] Referring to FIGS. 2 and 5-8, the connector 1000 further comprises a second fastener 300, a shielding member 400, and a gasket 500. The second fastener 300 is provided below the top wall 230 between the two side walls 210 and is matched with the first fastener 100 so as to secure the wire. The first fastener 100 is configured as a bolt, the second fastener 300 is configured as a nut, and the gasket 500 is abutted against below a head of the bolt so as to secure the wire between the top wall 230 of the housing 200 and the gasket 500.

[0031] The shielding member 400 is provided between the two side walls 210 so as to at least partially wrap or completely wrap the second fastener 300 and a portion of the first fastener 100 passing through the top wall 230 together with the housing 200, so that there is no gap between the second fastener 300 and the housing 200. An absence of the gap between the second fastener 300 and the housing 200 not only greatly eliminates a signal distortion, such as passive intermodulation, caused by this gap, improves a signal integrity of the connector 1000, but also makes the second fastener 300 more firmly installed in the housing 200 and less prone to falling, further improving the reliability of the connector 1000.

[0032] Referring to FIGS. 2 and 4-8, the shielding member 400 is provided with a groove 410 and an accommodating hole 420. The groove 410 configured as a bracket shape is located at one end 401 (i.e., an upper end) of the shielding member 400 abutting against the top wall 230 so as to accommodate the second fastener 300. The accommodating hole 420 is communicated to a bottom side 411 of the groove 410 so as to accommodate a portion of the first fastener 100 passing through the second fastener 300. In the illustrated embodiment, two opposite sides of the groove 410 are both open (see FIGS. 2 and 6-8), that is, the bracket-shaped groove 410 is configured to have two openings to expose two opposite sides of the second fastener 300, so that the exposed opposite sides of the second fastener 300 are abutted against the opposite side walls 210, respectively, and the second fastener 300 is completely wrapped by the two side walls 210 and the top wall 230 of the housing 200, and the shielding member 400 together. However, the present disclosure is not limited to this, and the opposite sides of the groove 410 may also be constructed as closed, so that the shielding member 400 may wrap the second fastener 300 along an entire circumference of the second fastener 300. The groove 410 may also be constructed to be any other suitable shape that may completely wrap the second fastener 300 together with the housing 200.

[0033] Referring to FIGS. 1-3, each of the two side walls 210 is provided with a connecting hole 213. The shielding member 400 is provided with a protrusion 430 on each of its two opposite sides, which is configured to be inserted into the connection hole 213 when the shielding member 400 is inserted into the housing 200 in an insertion direction D (i.e., a direction from bottom to top in FIG. 2), so that the shielding member 400 may be installed in place and fixed in the housing 200, thereby separating the other end 402 (i.e., the lower end) of the shielding member 400 facing away from the top wall 230 from the connecting area 2100 of the circuit board 2000.

[0034] In one embodiment of the present disclosure shown in FIGS. 2 and 6, the shielding member 400 is further provided with an elastic arm 440 on each of its two opposite sides, which extends from a main body of the shielding member 400 towards the other end 402 thereof and may be movable in a direction orthogonal to the insertion direction D. The protrusion 430 is provided on the elastic arm 440. The arrangement of the elastic arm 440 greatly facilitates installing the shielding member 400 in place in the housing 200 and fixing the shielding member 400 in the housing 200. Each of the two openings 412 of the bracket-shaped groove 410 is located on the same side of the shielding member 400 as the corresponding one of the protrusions 430 (see FIGS. 2 and 6-8).

[0035] Referring to FIG. 9, the present disclosure also includes a connector assembly 3000. The connector assembly 3000 comprises: a bus 600; a first pair of connectors 700, a second pair of connectors 800 and a third pair of connectors 900 electrically connected to one end of the bus 600; a first pair of mating connectors 700, a second pair of mating connectors 800 and a third pair of mating connectors 900 electrically connected to the other end of the bus 600. According to practical use, the bus 600 is selected from one of a thick copper bar, a thin copper bar, and a cable. A fixing point 610 is provided on a main body of the bus 600 so as to fix the bus 600 to a corresponding position on the circuit board.

[0036] For clarity, only parts of the circuit board connected to the three pairs of connectors 700, 800, 900, and the three pairs of mating connectors 700, 800, 900 are shown in FIG. 9. Each of the three pairs of connectors 700, 800, 900, and the three pairs of mating connectors 700, 800, 900 is configured to have a structure identical to that of the aforementioned connector 1000. Each of the connectors is correspondingly installed in a connecting area 2100 on the circuit board 2000, allowing the bus 600 to be connected between the three pairs of connectors 700, 800, 900, and the three pairs of mating connectors 700, 800, 900 in a bridging manner.

[0037] The first pair of connectors 700 is configured to transmit a control signal, and the first pair of mating connectors 700 is configured to receive the control signal. The second pair of connectors 800 is configured to transmit a power signal, and the third pair of connectors 900 is configured to transmit another power signal. The second pair of mating connectors 800 is configured to receive the power signal, and the third pair of mating connectors 900 is configured to receive the another power signal.
