Description

Technical Field

[0001] The utility model relates to the technical field of electrical connection, and more specifically to a connector. Background Art

[0002] For high-voltage connectors, the working voltage often exceeds the safe voltage that the human body can withstand. In order to prevent people from accidentally touching and getting electric shock, the high-voltage terminals in the connector should meet the IPXXB hand-proof level requirements. It is necessary to ensure that when the connector is not mated, fingers cannot touch the internal conductive terminals.

[0003] At the same time, in order to ensure that the terminal is inserted into place and to improve the holding force of the terminal in the plastic shell, a locking mechanism is often added to the terminal. Generally, a separate locking mechanism is provided to prevent the terminal from detaching from the shell, which makes the entire connector structure complicated.

[0004] In summary, how to effectively solve the problem of complex structure and inconvenient operation of current connectors is an urgent problem that technicians in this field need to solve. Utility Model Content

[0039] In some embodiments, the present embodiment provides a connector, which only or at least includes a housing 1 , a terminal 3 and an anti-hand-touch structure 2 .

[0040] The terminal 3 is inserted into the housing 1 along the first direction to be fixed and protected by the housing 1. The terminal 3 is generally a sheet-shaped terminal, which serves as an electrical connection structure. The shapes of the housing 1 and the terminal 3 can be specifically set according to specific needs. In order to facilitate plugging, a socket 16 is provided on one side of the housing 1 in the first direction to match the terminal 3.

[0041] The housing 1 has a window on one side along the second direction so that other electrical connection structures can be inserted into the window. It should be noted that the second direction and the first direction are two intersecting directions, such as two perpendicular directions or two nearly perpendicular directions.

[0042] The anti-touch structure 2 is plugged into the housing 1 along the second direction, and covers the terminal 3 on the window side to achieve an anti-touch effect. The anti-touch structure 2 and the housing 1 are matched by a multi-stage elastic snap-in to prevent the anti-touch structure 2 from being separated from the housing 1. The multi-stage elastic snap-in refers to a structure with multiple snap-in positions in the second direction, such as at least a primary snap-in position and a secondary snap-in position. When the anti-touch structure 2 is in the primary snap-in position or the secondary snap-in position relative to the housing 1, it can maintain the current position to form a relative fixation between the two to avoid separation. To enter the secondary snap-in position from the primary snap-in position, it needs to be further subjected to external force. When there are only primary snap-in positions and secondary snap-in positions, the multi-stage elastic snap-in can also be called a secondary elastic snap-in.

[0043] A locking structure is provided between the anti-touch structure 2 and the terminal 3 to prevent the terminal 3 from being separated from the housing when entering the locking position, that is, to prevent the terminal 3 from being separated from the housing along the plugging direction, so as to be constrained in the plugging direction. The locking structure generally includes a protrusion and a bayonet that are plugged in the second direction, and the two side walls of the bayonet in the first direction limit the protrusion located therein to perform locking.

[0044] Specifically, when the anti-hand-touch structure 2 moves to the multi-level elastic buckle in the first-level locking position, the locking structure disengages from the locking position, that is, it has not yet entered the locking position, that is, the corresponding latch has not yet entered the latch mouth. At this time, the locking structure does not constrain the terminal 3 and the housing 1. In the absence of other constraints, the terminal 3 can be freely plugged in and out of the housing 1.

[0045] When the anti-hand-touch structure 2 moves along the second direction to the multi-stage elastic buckle in the secondary snap-in position, the locking structure enters the locking position, that is, the corresponding snap-in protrusion enters the corresponding snap-in slot. At this time, the locking structure constrains the terminal 3 and the housing 1 to prevent the terminal 3 from detaching from the housing 1, thereby achieving the predetermined locking.

[0046] When in use, before inserting the terminal 3, the anti-touch structure 2 and the housing 1 can be assembled in advance. At this time, the anti-touch structure 2 moves to the multi-stage elastic buckle and is located at the first-stage clamping position. At this time, the anti-touch structure 2 and the housing 1 form an assembly part and will not be separated. Then insert the terminal 3 into the housing 1, and then further push the anti-touch structure 2 so that the anti-touch structure 2 moves to the multi-stage elastic buckle and is located at the second-stage clamping position. At this time, the anti-touch structure 2 and the housing 1 are kept in the current position by the multi-stage elastic buckle, and the locking structure enters the locking position to constrain the terminal 3 and the housing 1 to prevent the terminal 3 from being separated from the housing 1. In the above connector, the locking structure is integrated on the anti-touch structure 2, and at the same time, through the multi-stage elastic buckle, it can be ensured that the assembly between the anti-touch structure 2 and the housing 1 meets the requirements before the terminal 3 is inserted, and the above overall structure is convenient and simple to operate. In summary, the connector can effectively solve the problems of complex structure and inconvenient operation of the current connector.

[0047] In some embodiments, further, the housing 1 and the terminal 3 can be connected by a pre-locking elastic buckle to prevent the terminal 3 from detaching from the housing 1. At this time, the pre-locking elastic buckle is a primary lock, and the above-mentioned locking structure is a secondary lock, so that the locking between the housing 1 and the terminal 3 can better meet the requirements. During installation, when the terminal 3 is pushed in, the terminal 3 is inserted into place, that is, the pre-locking elastic buckle is in the locking position, at which time the position of the terminal 3 and the housing 1 can be ensured, and then the anti-touch structure 2 is further pushed to ensure the accuracy of the connection.

[0048] In some embodiments, the multi-stage elastic buckle has a multi-stage snap-in position, which can be realized by a bayonet with multiple elastic convexities, or by a elastic convexity with multiple bayonet ports. Specifically, the multi-stage elastic buckle can include a first elastic convexity 21 and multiple first bayonet ports 11. The elastic convexity refers to a convexity connected to an elastic structure, such as the elastic handle as shown in the figure. When entering the bayonet, under the action of external force, the convexity is subjected to force, which is transmitted to the elastic structure, causing the elastic structure to deform, and then the convexity is displaced to avoid the blocking structure until it enters the bayonet, and then the elastic structure is reset to ensure that the convexity is located in the bayonet.

[0049] Specifically, the first elastic protrusion 21 can be arranged on the anti-touch structure 2, and the plurality of first bayonet holes 11 can be arranged in parallel along the second direction and arranged on the housing 1. Of course, the arrangement can also be reversed. When a plurality of multi-stage elastic buckles are arranged, the arrangement methods of different multi-stage elastic buckles can be different. It is more convenient to arrange the first elastic protrusion 21 on the anti-touch structure 2.

[0050] In some embodiments, in order to facilitate the plugging between the anti-touch structure 2 and the housing 1, the anti-touch structure 2 preferably includes a covering portion 22 for covering the terminal 3 and plugging protrusions 23 arranged at both ends of the covering portion 22 in the first direction. Correspondingly, the inner cavity of the housing 1 is provided with slots 12 matching the plugging protrusions 23 at both ends in the first direction, so that the anti-touch structure 2 and the housing 1 are plugged in at both ends in the first direction through the plugging protrusions 23 and the slots 12. Of course, the plugging protrusions 23 can also be arranged on the housing 1, and the slots 12 can be correspondingly arranged on the anti-touch structure 2, or multiple groups of plugging protrusions 23 and slots 12 can be cross-arranged on the housing 1 and the anti-touch structure 2.

[0051] In some embodiments, a first snap-in 11 can be provided on the outer side of the slot wall of the slot 12. In this case, a gap is formed between the first elastic snap-in protrusion 21 and the insertion protrusion 23 to avoid the slot wall of the slot 12. At the same time, the first elastic snap-in protrusion 21 is conveniently provided with an elastic handle so as to have a better elastic space.

[0052] In some embodiments, as described above, only one set of multi-stage elastic buckles may be provided, but in order to improve the uniformity of the overall force, the anti-touch structure 2 may be provided with first elastic clips 21 at both ends in the first direction, that is, correspondingly, the housing 1 may be provided with multiple sets of first clips 11.

[0053] Furthermore, the anti-touch structure 2 may have first elastic protrusions 21 arranged oppositely or oppositely at one or both ends in the first direction and on both sides in the third direction, so as to be uniformly constrained in the third direction; wherein the third direction is perpendicular to both the first direction and the second direction. As shown in the accompanying drawings, the anti-touch structure 2 is provided with two first elastic protrusions 21 at both ends in the first direction, and at either end, the two first elastic protrusions 21 are located on both sides of the insertion protrusion 23 in the third direction, and the protrusions of the two first elastic protrusions 21 are arranged oppositely. That is, the anti-touch structure 2 is provided with four first elastic protrusions 21 in total.

[0054] Specifically, an assembly structure may be provided between the two insertion protrusions 23 , and the assembly structure has an assembly groove 25 matched with the terminal 3 .

[0055] In some embodiments, generally, a plurality of terminals 3 are provided to fit on the housing 1. Specifically, two terminals 3 are provided, the two terminals 3 are arranged side by side along the third direction and are respectively plugged into the housing 1, and the two anti-touch structures 2 are respectively used to cover the two terminals 3 and are respectively connected to the housing 1 to avoid mutual interference. Specifically, a partition 15 can be provided in the inner cavity of the housing 1 to form two cavities, each of which is provided with a terminal 3 and a corresponding anti-touch structure 2.

[0056] In some embodiments, the locking structure may include a locking bayonet 31 located on the terminal 3 and a locking protrusion 24 disposed on the anti-touch structure 2, wherein the locking protrusion 24 moves relative to the locking bayonet 31 along the second direction so that the locking structure enters and exits the locking position, that is, the locking protrusion 24 enters the locking bayonet 31, and the locking structure enters the locking position, while the locking protrusion 24 does not enter the locking bayonet 31, and the locking structure does not enter the locking position. One or more groups of locking structures may be provided. The locking protrusion 24 is arranged on the anti-touch structure 2, which can avoid having a protruding structure on the terminal 3 to facilitate the plug-in fit between the terminal 3 and the housing 1.

[0057] In some embodiments, the pre-locking elastic buckle can include a second elastic protrusion 13 provided on the housing 1 and a second bayonet 32 ​​provided on the terminal 3. Since the terminal 3 is generally a metal part, it is inconvenient to arrange the second elastic protrusion 13.

[0058] In some embodiments, the housing 1 may be provided with a mounting groove 14 that is arranged opposite to the cover portion 22 of the anti-touch structure 2 to match the terminal 3, that is, the cover portion 22 and the mounting groove 14 respectively match the two sides of the terminal 3 in the second direction. A second elastic protrusion 13 is provided on the groove wall of one side of the mounting groove 14, so that the second elastic protrusion 13 is conveniently arranged.

[0059] It should be noted that the housing 1 and the finger-protection structure 2 are both integrally formed parts, such as integrally formed plastic parts, and the terminal 3 is generally a metal part.

[0060] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0061] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
