Description

Technical Field

[0001] This utility model belongs to the field of electrical connectors, and particularly relates to an electrical connector and connector assembly. Background Technology

[0002] With the increasing miniaturization and integration of electronic devices, the design optimization of electrical connectors, as core components of electrical connections, is crucial. To address the inconvenience of unlocking existing locking mechanisms, a pull-tap method has been adopted for unlocking. In traditional pull-tap unlocking designs, the pull strap often needs to pass through the connector housing to function, or a special structure needs to be added to the housing for it to pass through.

[0003] Meanwhile, in existing electrical connectors, the locking mechanism has a very limited function, merely serving to limit the movement of conductive terminals. Within the limited internal space of an electrical connector, this single-function component fails to fully realize its potential value or effectively integrate with other functional requirements. In the current pursuit of higher integration and space utilization, the limitations of traditional locking mechanisms and pull-through methods are becoming increasingly apparent, unable to meet the stringent requirements of electronic devices for electrical connectors in terms of performance, structural compactness, and other aspects. Utility Model Content

[0004] The purpose of this invention is to provide an electrical connector and connector assembly to overcome at least one of the aforementioned defects in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The present invention provides an electrical connector comprising a housing, a locking member, conductive terminals, a fastening member, and a pull strap. The housing contains a plurality of conductive terminals, each having a limiting portion. The locking member is installed in the housing and is inserted into the housing and abuts against and / or close to the end wall of the limiting portion to hold the conductive terminals in the desired position. At least one side wall of the housing has a fastening member, and the pull strap passes through the locking member and is connected to the fastening member.

[0007] Preferably, the conductive terminals include two rows of terminal blocks spaced apart, each row of terminal blocks including several conductive terminals spaced apart along the length of the housing, and two locking members that cooperate with the upper and lower rows of terminal blocks respectively.

[0008] Preferably, the locking member near the latch has a protruding extension that extends through the housing, with the end of the extension positioned away from the housing relative to the end of the latch.

[0010] Preferably, the locking member includes a base, a stop arm, and a first locking part. One end wall of the base has a plurality of stop arms, which are disposed against and / or close to the end wall of the limiting part. At least one side wall of the base has at least one first locking part, and the interior of the housing has a second locking part that engages with the first locking part.

[0011] Preferably, the extension protrudes outward from the base.

[0012] Preferably, the extension has a third locking portion, and the housing has a fourth locking portion that cooperates with the third locking portion.

[0013] Preferably, it also includes a cable, one end of which is electrically connected to a conductive terminal, and the cable exits from one side of the housing.

[0014] Preferably, the locking element has a channel for the cable to pass through.

[0033] Example 1:

[0034] like Figures 1 to 6As shown, this embodiment provides an electrical connector, specifically a power connector, including a housing 1, a locking member 2, conductive terminals 3, a locking fastener 4, a pull strap 5, and a cable 6. The housing 1 contains several conductive terminals 3, each with a limiting portion 31. In this embodiment, the locking member 2 is installed in the housing 1 and inserted into the housing 1 close to the rear end wall of the limiting portion 31, specifically located on the right side of the right end wall of the limiting portion 31, to hold the conductive terminals 3 in the desired position. The upper side wall of the housing 1 has a locking fastener 4. The pull strap 5 passes through the locking member 2 and connects to the locking fastener 4. The left end of the cable 6 is electrically connected to the conductive terminals 3, and the cable 6 exits from the right side of the housing 1. In other embodiments, both the upper and lower side walls of the housing 1 may have locking fasteners 4.

[0035] In terms of structural design and stability, by installing the locking member 2 on the housing 1 and having it cooperate with the limiting part 31 of the conductive terminal 3, the conductive terminal 3 can be accurately and securely held in the required position. This design provides reliable limiting support for the conductive terminal 3, effectively reducing the risk of displacement of the conductive terminal 3 due to external forces such as vibration and impact during operation, thereby ensuring the stability and reliability of electrical signal transmission and significantly improving the overall performance of the electrical connector.

[0036] From the perspective of space utilization and structural simplification, the ingenious design of the pull strap 5 passing through the locking member 2 and connecting to the fastener 4 avoids the need for an additional complex pull strap 5 passage structure on the housing 1. This not only maintains the integrity of the housing 1 and enhances its protection of internal components, but also greatly simplifies the overall structure of the electrical connector. Reducing unnecessary structural design allows for a more compact and rational internal space layout, providing strong support for the miniaturization and integration of electrical connectors and meeting the stringent requirements of modern electronic devices for component size and functional integration.

[0037] In terms of functional integration and expansion, the locking element 2 is no longer limited to limiting the conductive terminal 3, but also takes on the new responsibility of providing a path for the pull strap 5 to pass through. This functional integration design fully taps into the potential value of the locking element 2, enabling the electrical connector to achieve the coordinated operation of multiple functions within a limited space.

[0038] The conductive terminals 3 include two rows of terminal blocks spaced apart, each row of terminal blocks including several conductive terminals 3 spaced apart along the length of the housing 1. There are two locking members 2, arranged vertically and respectively, cooperating with the upper and lower rows of terminal blocks. The locking member 2 near the latching member 4 has a protruding extension 21 that passes through the housing 1, with its end positioned away from the housing 1 relative to the end of the latching member 4. In this embodiment, the upper latching member 4 has an upwardly protruding extension 21, with its top end positioned above the top end of the latching member 4. The extension 21 prevents other components from accidentally locking the latching member 4.

[0039] The extension 21 has a through hole 22, the fastener 4 has a connecting hole 41, the pull strap 5 passes through the through hole 22 and connects to the connecting hole 41, the connecting hole 41 and the through hole 22 are offset, and the through hole 22 is positioned relative to the connecting hole 41 and close to the housing 1. In this embodiment, the connecting hole 41 is located to the upper left of the through hole 22.

[0040] Through its unique structural design, this electrical connector allows for quick unlocking and removal in a single operation. To unlock, simply pull the pull strap 5 to the right. Due to the carefully designed positional relationship between the through-hole 22 and the connecting hole 41 through which the pull strap 5 passes, the pull strap 5 is positioned at an angle between these two holes. As the pull strap 5 is pulled to the right, it applies a downward and rightward force to the locking element 4. According to the principle of force decomposition, this force can be divided into two components: a downward force presses down on the locking element 4, easily unlocking the connector; while the rightward force acts directly on the electrical connector, helping to smoothly remove it from the mating connector. This ingenious design greatly enhances the ease of use and efficiency of the electrical connector in practical applications.

[0041] The locking component 2 includes a base 23, a stop arm 24, and a first locking part 25. The left end wall of the base 23 has several stop arms 24, which are positioned close to the right end wall of the limiting part 31. Each of the front and rear side walls of the base 23 has a first locking part 25, and each of the front and rear side walls of the upper side wall of the base 23 has a first locking part 25. The interior of the housing 1 has a second locking part 11 that engages with the first locking parts 25. In this embodiment, the first locking part 25 is a locking block, and the second locking part 11 is a locking hole. In other embodiments, the first locking part 25 can be a locking hole, and the second locking part 11 can be a locking block. The locking component 2 is installed through the first locking part 25 and the second locking part 11, and this interlocking installation method greatly simplifies the assembly process. Furthermore, the first locking part 25 and the second locking part 11 cooperate with each other to provide stable support and limitation for the locking component 2 from multiple directions.

[0042] The extension 21 extends outward from the base 23, which makes the extension 21 and the base 23 form a continuous integral structure with higher structural strength.

[0043] The extension 21 has a third locking part 211, and the housing 1 has a fourth locking part 12 that cooperates with the third locking part 211. In this embodiment, the third locking part 211 is a locking block, and the fourth locking part 12 is a locking groove. In other embodiments, the third locking part 211 may be a locking groove, and the fourth locking part 12 may be a locking block. This improves the assembly stability between the extension 21 and the housing 1.

[0044] The locking element 2 has a channel 26 through which the cable 6 passes, which not only protects the cable 6, but also facilitates wiring and enhances the stability of the cable 6.

[0046] This embodiment also provides a connector assembly, including the electrical connector of Embodiment 1 and a mating connector (not shown) that mates with the electrical connector.
