Description

Technical Field

[0001] The present invention relates to the technical field of electrical connectors, and particularly to an electrical connector with adjustable insertion height. Background Art

[0002] An electrical connector refers to a connecting device between wires or conductor lines in a device, which is used to achieve smooth flow of current, connect two sub-electronic systems, and complete electrical connection. The electrical connector is also called a circuit connector or an electrical connector, which is a subdivision field of electronic components and is mainly used for connecting between circuits. The metal terminal pieces are contact-connected through two mutually matching connectors to achieve electrical connection and conduction.

[0003] The utility model with the publication number CN212626269U discloses a power socket adapter with adjustable height, which solves the problem that the power socket cannot be used because the user's hand cannot reach into the gap between the power socket and the bed or desk. There is basically no obstruction at the bottom of the socket strip, which does not affect the bottom heat dissipation. In addition, the present invention has no scattered power cords, so it has good safety performance and is convenient to use. Moreover, the height of the present invention can be adjusted, and the card seat is clamped on the power socket, having the effect of dust and water prevention.

[0004] The utility model with the publication number CN107369931B discloses an interface connector with adjustable height, which realizes nine-level different height adjustments, and sets the multi-stage fixing unit of the connecting elastic piece and the multi-stage limiting unit of the supporting part to be engaged with each other for fixing in the horizontal direction to realize the first adjustment of height. According to the cooperation between the multi-stage supporting units on the supporting part and the circuit board, the second height determination is realized, effectively maintaining the contact area between each stage of the supporting unit and the circuit board.

[0005] However, the above electrical connectors with adjustable height still have the following problems in actual use: Although the plug-in connection in different situations is realized through the connector with variable height, such connectors need to rely on the bearing element when adjusting the height, and the use height can be positioned only through the positioning realized by the bearing element. At the same time, the metal terminals inside such connectors can only extend the wires, and the stability and locking positioning of the connection cannot be guaranteed during the contact conduction process, and it is easy to fall off and separate under external force after adjusting the height.

[0006] Therefore, we propose an electrical connector with adjustable insertion height to solve the problems raised above. Summary of the Invention

[0007] The object of the present invention is to provide an electrical connector with adjustable insertion height. To solve the problem that in the prior art, a connector with variable height is used to achieve insertion connection in different situations. However, when adjusting the height of such a connector, it needs to rely on a bearing element, and the positioning can only be achieved through the bearing element to position the use height. At the same time, the metal terminals inside such a connector can only extend the wire, and the stability and locking positioning of the connection cannot be guaranteed during the contact conduction process, and it is easy to fall off and separate under external force after adjusting the height.

[0008] To achieve the above object, the present invention provides the following technical solution: An electrical connector with adjustable insertion height, including a main connector body and a sub-connector body that are inserted into each other in an up-and-down manner, and mounting brackets are fixedly arranged at the left ends of both the main connector body and the sub-connector body; further comprising:

[0010] A contact mechanism is arranged inside the main connector body, and the contact mechanism includes a main contact metal sheet and a sub-contact metal sheet, and the main contact metal sheets are equidistantly installed inside the main connector body in a front-back symmetric manner.

[0011] Preferably, the adaptation mechanism includes folding elastic pieces, and the folding elastic pieces are fixedly installed on both the left and right sides inside the adaptation frame, and the top ends of the unlocking brackets included in the adaptation mechanism slidably penetrate through the outer surface of the top surface of the adaptation frame.

[0012] Preferably, the inner ends of the folding elastic pieces included in the adaptation mechanism are fixedly connected to the middle outer walls of the unlocking brackets, and the symmetrically arranged unlocking brackets are distributed in an "L" - shaped structure with opposite directions, and the unlocking brackets in the initial state are close to the inner side of the adaptation frame.

[0013] Preferably, the contact mechanism includes a sliding contact piece, and the sliding contact piece is in sliding contact with the outer side of the bottom end of the main contact metal sheet, and a limiting sliding groove is opened at one end of the sliding contact piece close to the main contact metal sheet.

[0014] Preferably, the contact mechanism includes a limiting sliding bar, and the limiting sliding bar is fixedly installed on the side of the main contact metal sheet close to the sliding contact piece, and the limiting sliding bar is slidably arranged inside the limiting sliding groove, and the height adjustment of the sliding contact piece is realized through the connection between the limiting sliding bar and the limiting sliding groove.

[0015] Preferably, the contact mechanism includes clamping bumps, and the clamping bumps are fixedly installed at the upper and lower ends inside the sliding contact piece, and the inner sides of the symmetrically arranged clamping bumps are both engaged with a resisting cross plate, and at the same time, the resisting cross plate elastically slides on the front and rear sides of the bottom end of the adapter frame.

[0016] Preferably, the secondary contact metal pieces included in the contact mechanism are equidistantly installed inside the secondary connector body in a front-back symmetric manner, and the secondary contact metal pieces and the primary contact metal pieces are connected up and down in a state with opposite directions, and the primary contact metal piece realizes connection conduction with the secondary contact metal piece at different heights through the sliding contact piece attached to the bottom end.

[0017] Preferably, a connection mechanism is provided at the bottom end of the main connector body, and the connection mechanism includes a support sliding plate, and the support sliding plate is slidably arranged on the front and rear sides of the bottom end of the main connector body, and the left and right sides of the top ends of the symmetrically arranged support sliding plates are both fixedly provided with the bottom ends of positioning sliding rods.

[0018] Preferably, the top end of the positioning sliding rod included in the connection mechanism is fixedly connected to the outer end of the adapter frame, and the positioning sliding rod and the main connector body are positioned through static friction, and the positioning sliding rod is used to limit the support sliding plate outside the main connector body, and then the length of the main connector body is changed through the support sliding plate.

[0019] Preferably, the connection mechanism includes locking positioning blocks, and the locking positioning blocks are symmetrically slidably arranged on the left and right sides of the bottom surface of the adapter frame, and the symmetrically arranged locking positioning blocks are fixedly connected to the bottom surface of the unlocking bracket, and the connection mechanism includes locking positioning grooves, and at the same time, the locking positioning grooves are symmetrically opened inside the top end of the secondary connector body, and the sliding insertion between the locking positioning grooves and the locking positioning blocks realizes the connection and unlocking of the secondary connector body and the main connector body.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: for the electrical connector with adjustable insertion height, the adapter frame drives the support sliding plate, the positioning sliding rod that is positioned with the main connector body through static friction ensures the height of the adapter frame, the sliding contact piece realizes the connection between the primary contact metal piece and the secondary contact metal piece, and the main connector body and the secondary connector body are locked to prevent loosening and disconnection under the action of external force. The specific content is as follows:

[0021] 1. By grasping the main connector body and pressing the adapter frame to move, the positioning sliding rod fixedly connected to the adapter frame slides through the main connector body, and at the same time, its connection with the main connector body is ensured through static friction, and then the height of the adapter frame is positioned through the positioning sliding rod after being adjusted to the required height.

[0022] Further, during the subsequent processing of the main connector body (such as overmolding, encapsulation, etc.), only a certain length of hollow position needs to be reserved at the movable space of the adaptation framework. The position of the adaptation framework can be adjusted by sliding the positioning slide bars on both sides thereof to adjust the use height of the main connector body, thus not affecting the processing such as overmolding of the main contact metal sheet.

[0023] 2. The movable adaptation framework is clamped between the upper and lower clamping bumps through the abutting cross plate. Thus, when the adaptation framework moves up and down to adjust the adaptation height, the sliding contact piece engaged is driven to descend by the abutting cross plate at its bottom end, thereby changing the use length of the main contact metal sheet. The main contact metal sheet and the sub-contact metal sheet can achieve stable contact connection through the conduction of the sliding contact piece.

[0024] The main contact metal sheet passes through the limiting slide bar through the limiting slide groove at the inner end of the sliding contact piece. Thus, when the sliding contact piece moves up and down, the limiting slide bar and the limiting slide groove connected in a "T" - shaped structure can ensure stability, improving the continuity during conduction with the sub-contact metal sheet.

[0025] 3. Slide the unlocking bracket inside the adaptation framework outwards, so that the locking positioning block at its bottom end moves synchronously, so that the locking positioning block is inserted into the locking positioning groove and slides inwards, realizing the locking connection between the main connector body and the sub-connector body through the adaptation framework, and avoiding the situation of loosening and disconnection under the action of external force.

[0039] See also Figures 1 - 11 , the present invention provides the following technical solutions:

[0040] Embodiment 1: In order to solve the problems existing in the use of existing electrical connectors, this embodiment adopts the following technical scheme: an electrical connector with adjustable plug-in height, including a main connector body 1 and a sub-connector body 2 that are plugged into each other in an up-and-down manner, and the left ends of the main connector body 1 and the sub-connector body 2 are fixedly provided with mounting brackets 3; an adapter mechanism is provided inside the main connector body 1, and the adapter mechanism includes an adapter frame 4, and unlocking brackets 5 are slidably provided on the left and right sides of the inside of the adapter frame 4.

[0041] A connecting mechanism is provided at the bottom end of the main connector body 1, and the connecting mechanism includes a supporting slide 14, and the supporting slide 14 is slidably provided on the front and rear sides of the bottom end of the main connector body 1, and the bottom ends of the positioning slide rods 15 are fixedly provided on the left and right sides of the top of the symmetrically provided supporting slide 14.

[0042] The top end of the positioning slide bar 15 included in the connecting mechanism is fixedly connected to the outer end of the adapter frame 4, and the positioning slide bar 15 is positioned with the main connector body 1 through static friction. Moreover, the positioning slide bar 15 is used to limit the support slide plate 14 outside the main connector body 1, and then change the length of the main connector body 1 through the support slide plate 14.

[0043] As Figures 1 - 2 , Figure 11 shown, when the main connector body 1 needs to be used for plugging with the sub-connector body 2 of different heights, after manually grasping the main connector body 1, press the adapter frame 4 slidably connected inside it to move. The positioning slide bar 15 fixedly connected to the adapter frame 4 slides through the main connector body 1. At the same time, its connection with the main connector body 1 is ensured through static friction. Furthermore, after adjusting to the required height, the height of the adapter frame 4 is positioned through the positioning slide bar 15.

[0044] The adapter frame 4 provided inside the main connector body 1 adjusts its height during the sliding process. At the same time, the positioning slide bar 15 drives the support slide plate 14 at the bottom to move, so that the support slide plate 14 changes its position on the front and back sides of the main connector body 1. Furthermore, the connection between the main connector body 1 and the sub-connector body 2 is realized through the support slide plate 14 instead of the main connector body 1, and at the same time, the length of the main connector body 1 is increased.

[0045] Embodiment 2: In order to solve the problems existing in the existing electrical connectors during use, therefore, in this embodiment, through the following technical solutions, a contact mechanism is provided inside the main connector body 1, and the contact mechanism includes a main contact metal sheet 6 and a sub-contact metal sheet 7.

Moreover, the limiting slide bar 11 is slidably arranged inside the limiting chute 10. Moreover, the height adjustment of the sliding contact piece 9 is realized through the connection between the limiting slide bar 11 and the limiting chute 10; the contact mechanism includes a clamping convex block 12, and the clamping convex blocks 12 are fixedly installed at the upper and lower ends of the inner side of the sliding contact piece 9. Moreover, a resisting cross plate 13 is clamped and arranged inside the symmetrically arranged clamping convex blocks 12. At the same time, the resisting cross plate 13 elastically slides on the front and back sides of the bottom end of the adapter frame 4.

[0047] The auxiliary contact metal sheet 7 included in the contact mechanism is equidistantly installed inside the auxiliary connector body 2 in a front-back symmetric manner, and the auxiliary contact metal sheet 7 is connected to the main contact metal sheet 6 in an up-down manner with opposite directions, and the main contact metal sheet 6 realizes the connection and conduction with the auxiliary contact metal sheet 7 at different heights through the sliding contact sheet 9 attached to the bottom end.

[0048] As Figures 5 - 8 shown, when the main contact metal sheet 6 arranged inside the main connector body 1 is adjusted in height by driving the adapter frame 4, the contact cross plates 13 elastically connected to the front and rear sides of the bottom end of the adapter frame 4 slide inwards, so that the adapter frame 4 is adjusted to be between the clamping bumps 12 at the upper and lower ends of the inner side of the sliding contact sheet 9. After the elastically connected contact cross plates 13 are reset, they are clamped between the clamping bumps 12 at the upper and lower ends. Furthermore, when the adapter frame 4 moves up and down to adjust the adaptation height, the clamped sliding contact sheet 9 is driven to descend through the contact cross plate 13 at its bottom end, thereby changing the usage length of the main contact metal sheet 6, and the main contact metal sheet 6 and the auxiliary contact metal sheet 7 can achieve stable contact connection through the conduction of the sliding contact sheet 9.

[0049] Furthermore, the main contact metal sheet 6 passes through the limit sliding groove 10 at the inner end of the sliding contact sheet 9 through the limit sliding bar 11. Furthermore, when the sliding contact sheet 9 moves up and down, the stability can be ensured through the limit sliding bar 11 and the limit sliding groove 10 connected in a "T" - shaped structure, improving the continuity during conduction with the auxiliary contact metal sheet 7.

[0050] Embodiment 3: In order to solve the problems existing in the existing electrical connectors during use, therefore, in this embodiment, through the following technical solutions, the adaptation mechanism includes a folding elastic sheet 8, and the folding elastic sheet 8 is fixedly installed on the left and right sides inside the adapter frame 4, and the top end of the unlocking bracket 5 included in the adaptation mechanism slides through the outer surface of the top surface of the adapter frame 4; the inner end of the folding elastic sheet 8 included in the adaptation mechanism is fixedly connected to the middle outer wall of the unlocking bracket 5, and the symmetrically arranged unlocking brackets 5 are distributed in an "L" - shaped structure with opposite directions, and the unlocking bracket 5 in the initial state is close to the inner side of the adapter frame 4.
