A double-pressure terminal connector

Abstract

This application relates to the technical field of connectors, and discloses a double-press terminal connector, which includes a male plug and a female plug. A receiving hole for inserting the male plug is provided on the female plug. A connecting strip is provided on the male plug, and an elastic first limiting strip and a second limiting strip are provided on the connecting strip. The first limiting strip and the second limiting strip are distributed along the insertion direction of the wiring part. Both the first limiting strip and the second limiting strip are bent towards the direction of the male plug. The wiring part is located between the bending part of the first limiting strip and the male plug. In this application, since both the first limiting strip and the second limiting strip are elastic, when the wiring part is inserted between the bending part of the first limiting strip and the male plug, the wiring part can drive the first limiting strip to deform. At this time, the distance between the first limiting strip and the male plug can change, and it is easier for the wiring part to push the first limiting strip to deform. The force applied to the wiring part is smaller than that in the background technology, so that the wiring part can be inserted into the male plug more easily.

Description

Technical Field

[0001] This application relates to the technical field of connectors, and in particular to a double-press terminal connector. Background Art

[0002] A connector is an electromechanical component used to connect a conductor to an appropriate mating component to achieve the connection and disconnection of a circuit. The connector includes a male plug and a female plug. The male plug is inserted into the female plug, and both the male plug and the female plug are connected to a wiring portion to achieve the connection of the circuit.

[0003] In the related art, the connector includes a male plug and a female plug. Two U-shaped strips are bent on the male plug. The U-shaped strips are bent towards the male plug, and the bent positions of the U-shaped strips abut against the wiring portion to fix the wiring portion and the male plug. A receiving hole is provided on the female plug for the male plug to be inserted. A limiting block is provided on the receiving hole to limit the male plug from being taken out of the receiving hole.

[0004] After the male plug and the female plug are assembled, the wiring portion needs to be inserted between the male plug and the bent portion of the U-shaped strip. Since the U-shaped strip is directly bent and formed, it is difficult to change the distance between the U-shaped strip and the male plug. Therefore, the staff needs to apply a relatively large force to insert the wiring portion. Summary of the Invention

[0005] In order to improve the problem that the wiring portion is difficult to insert into the male plug, this application provides a double-press terminal connector.

[0006] A double-press terminal connector provided by this application adopts the following technical solutions:

[0007] A double-press terminal connector includes a male plug and a female plug. A receiving hole for the male plug to be inserted is provided on the female plug. A connecting strip is provided on the male plug. An elastic first limiting strip and a second limiting strip are provided on the connecting strip. The first limiting strip and the second limiting strip are distributed along the insertion direction of the wiring portion. Both the first limiting strip and the second limiting strip are bent towards the male plug. The wiring portion is located between the bent portion of the first limiting strip and the male plug.

[0008] By adopting the above technical solution, since both the first limiting strip and the second limiting strip are elastic, when the wiring part is inserted between the bent part of the first limiting strip and the male plug, the wiring part can drive the first limiting strip to deform. At this time, the distance between the first limiting strip and the male plug can be changed, and the first limiting strip and the second limiting strip are distributed along the insertion direction of the wiring part. The wiring part can more easily push the first limiting strip to deform, and the acting force applied to the wiring part is smaller than that in the background technology, so that the wiring part can be more easily inserted into the male plug; because the first limiting strip and the second limiting strip are distributed along the insertion direction of the wiring part, during the insertion process of the wiring part, the wiring part first abuts against the first limiting strip, and then the wiring part abuts against the second limiting strip, so that the staff can feel two-stage limiting during the insertion process of the wiring part, making it difficult for the wiring part to be pulled out of the male plug.

[0009] Optionally, a relief strip is bent on the first limiting strip, and the distance between the relief strip and the male plug gradually increases along the direction from the connecting strip to the first limiting strip.

[0010] By adopting the above technical solution, since the distance between the relief strip and the male plug gradually increases along the direction from the connecting strip to the first limiting strip, during the insertion process of the wiring part, the wiring part can abut against the relief strip, so that the wiring part drives the first limiting strip to deform through the relief strip, so as to facilitate the first limiting strip to limit the wiring part, making the first limiting strip better adapt to the wiring part with a larger thickness.

[0011] Optionally, a limiting block is bent on the second limiting strip, and the distance between the limiting block and the male plug gradually increases along the direction from the connecting strip to the second limiting strip. During the insertion process of the wiring part into the male plug, the wiring part abuts against the first limiting strip first and then abuts against the second limiting strip.

[0012] By adopting the above technical solution, since the distance between the limiting block and the male plug gradually increases along the direction from the connecting strip to the second limiting strip, the wiring part abuts against the limiting block and the bent part of the second limiting strip, making the bent part of the second limiting strip and the limiting block smoother, reducing the wear of the bent part of the second limiting strip and the limiting block on the wiring part.

[0013] Optionally, a convex block is provided on the male plug, and the convex block is located on the insertion path of the wiring part. When the wiring part abuts against the convex block, the wiring part abuts against the first limiting strip and the second limiting strip.

[0014] By adopting the above technical solution, since the convex block is located on the insertion path of the wiring part, the convex block restricts the wiring part from continuing to move, thereby fixing the insertion position of the wiring part and making the connection between the wiring part and the male plug more stable.

[0015] Optionally, one side opening of the receiving hole is an entrance for inserting a male plug. Elastic strips are provided on the inner wall of the receiving hole, and the elastic strips are bent in the direction of the male plug. The elastic strips are located on the moving path of the male plug. When the male plug is inserted into the receiving hole, the male plug is located on the side of the elastic strips away from the entrance of the receiving hole.

[0016] By adopting the above technical solution, when the male plug is inserted into the receiving groove, the male plug drives the elastic strips to deform, so that the elastic strips do not restrict the insertion of the male plug. When the male plug is inserted in place, the male plug does not abut against the elastic strips. At this time, due to elastic reset, the elastic strips are located on the moving path of the male plug. Moreover, since the male plug is located on the side of the elastic strips away from the entrance of the receiving hole, the elastic strips restrict the movement of the male plug, realizing that the male plug is stably located in the female plug.

[0017] Optionally, an elastic fixing spring piece is provided on the female plug, and the fixing spring piece is deformed in the direction of the first limiting strip; when the male plug is inserted into the receiving hole, the fixing spring piece drives the first limiting strip to deform in the direction of the male plug.

[0018] By adopting the above technical solution, the fixing spring piece deforms in the direction of the first limiting strip, so that the fixing spring piece drives the first limiting strip to move, enabling the first limiting strip to deform in the direction of the male plug, further strengthening the limitation of the first limiting strip on the male plug, and making it difficult for the male plug to disengage from the first limiting strip.

[0019] Optionally, a placement groove is provided on the female plug, and a placement strip is detachably connected in the placement groove. A placement elastic block is provided on the placement strip; when the placement strip is located in the placement groove, the placement elastic block drives the fixing spring piece to abut against the first limiting strip.

[0020] By adopting the above technical solution, the staff installs the placement strip in the placement groove, so that the placement strip drives the fixing spring piece to move through the placement elastic block, increasing the acting force of the fixing spring piece on the first limiting strip, thereby enabling the first limiting strip to increase the restrictive effect on the male plug; when the staff inserts the wrong wiring part into the male plug, the staff removes the placement strip from the placement groove, releasing the acting force of the placement strip on the fixing spring piece, reducing the acting force of the fixing spring piece on the first limiting strip, and enabling the wiring part to be taken out from the first limiting strip; through the installation or removal of the placement strip, the connector has a locked state or a pre-fixed state.

[0021] Optionally, a U-shaped strip is provided on the female plug. One end of the U-shaped strip is located on the side of the fixing spring piece facing the first limiting strip, and the other end of the U-shaped strip is located on the side of the placement strip away from the fixing spring piece; when the fixing spring piece deforms towards the first limiting strip, the end of the U-shaped strip close to the first limiting strip drives the other end of the U-shaped strip to abut against the placement strip.

[0022] By adopting the above technical solution, when the fixing elastic piece deforms towards the direction of the first limiting strip, one end of the U-shaped strip is driven to move by the fixing elastic piece. At this time, the other end of the U-shaped strip also moves in the same direction, so that the U-shaped strip can abut against the placing strip, making the placing strip not easy to move in the female plug due to the restriction of the U-shaped strip, and making the placing strip not easy to disengage from the placing groove, further strengthening the mutual fixing effect between the placing strip and the female plug.

[0023] Optionally, a first stop strip is provided on the first limiting strip, and the distance between the first stop strip and the connecting strip gradually increases along the direction from the first limiting strip to the connecting strip; when the wiring part abuts against the first limiting strip, the first stop strip can abut against the wiring part.

[0024] By adopting the above technical solution, when the wiring part abuts against the first limiting strip, the first limiting strip deforms in the direction away from the male plug, so that the first limiting strip drives the first stop strip to deform in the direction of the male plug, and the acting force between the first stop strip and the wiring part increases, making the wiring part not easy to disengage from the first limiting strip.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Since both the first limiting strip and the second limiting strip are elastic, when the wiring part is inserted between the bent part of the first limiting strip and the male plug, the wiring part can drive the first limiting strip to deform. At this time, the distance between the first limiting strip and the male plug can be changed, and the acting force applied to the wiring part is smaller than that in the background technology, so that the wiring part can be inserted into the male plug more easily; since the first limiting strip and the second limiting strip are distributed along the insertion direction of the wiring part, during the insertion process of the wiring part, the wiring part first abuts against the first limiting strip, and then the wiring part abuts against the second limiting strip, so that the staff can feel two-stage limiting during the insertion process of the wiring part, making the wiring part not easy to be pulled out of the male plug.

[0027] 2. When the fixing elastic piece deforms towards the direction of the first limiting strip, one end of the U-shaped strip is driven to move by the fixing elastic piece. At this time, the other end of the U-shaped strip also moves in the same direction, so that the U-shaped strip can abut against the placing strip, making the placing strip not easy to move in the female plug due to the restriction of the U-shaped strip, and making the placing strip not easy to disengage from the placing groove, further strengthening the mutual fixing effect between the placing strip and the female plug.

Detailed implementation manners

[0035] The following further elaborates on this application in conjunction with the Figures 1-6 accompanying drawings.

[0036] Embodiment 1

[0037] This embodiment discloses a double-press terminal connector. Referring to Figure 1 , a double-press terminal connector includes a male plug 1 and a female plug 2. A receiving hole 21 for inserting the male plug 1 is formed on the female plug 2. One side opening of the receiving hole 21 is an inlet, and the other side opening of the receiving hole 21 is an outlet. The inlet is for inserting the male plug 1 to achieve the assembly of the male plug 1 and the female plug 2, and the outlet is for inserting a wiring part into the male plug 1 to achieve the assembly of the wiring part and the male plug 1.

[0038] Referring to Figure 1 and Figure 2 , two connecting plates 11 are integrally formed on the male plug 1, and the two connecting plates 11 are respectively located on both sides of the male plug 1. Both connecting plates 11 are perpendicular to the male plug 1, and a wiring part can be inserted between the two connecting plates 11.

[0039] Referring to Figure 2 , a connecting strip 12 is integrally formed on the connecting plate 11, and the connecting strip 12 extends towards the other connecting plate 11. A first limiting strip 13 and a second limiting strip 14 are integrally formed on the surface of the connecting strip 12. The first limiting strip 13 and the second limiting strip 14 are respectively located on different sides of the connecting strip 12, and the first limiting strip 13 is located on the side of the second limiting strip 14 closer to the outlet.

[0040] Referring to Figure 2, the distance between the first limiting strip 13 and the male plug 1 gradually increases along the direction from the first limiting strip 13 to the second limiting strip 14. A relief strip 131 is integrally formed on the first limiting strip 13. The distance between the relief strip 131 and the male plug 1 gradually decreases along the direction from the first limiting strip 13 to the second limiting strip 14, and the relief strip 131 is located on the side of the first limiting strip 13 away from the connecting strip 12. When the wiring part is inserted into the male plug 1, the wiring part abuts against the bent part of the first limiting strip 13 and the relief strip 131.

[0041] Refer to Figure 2 , the distance between the second limiting strip 14 and the male plug 1 gradually decreases along the direction from the first limiting strip 13 to the second limiting strip 14. A limiting block 141 is integrally formed on the second limiting strip 14. The distance between the limiting block 141 and the male plug 1 gradually increases along the direction from the first limiting strip 13 to the second limiting strip 14, and the limiting block 141 is located on the side of the second limiting strip 14 away from the connecting strip 12. When the wiring part is inserted into the male plug 1, the wiring part abuts against the bent part of the second limiting strip 14 and the limiting block 141.

[0042] Refer to Figure 1 and Figure 3 , two elastic strips 22 are fixedly connected to the hole wall of the receiving hole 21. The elastic strips 22 have the ability of elastic deformation. The elastic strips 22 deform towards the male plug 1, and both of the two elastic strips 22 are on the path of the overall insertion of the male plug 1. Two stop blocks 23 are fixedly connected to the hole wall of the receiving hole 21. The two stop blocks 23 are located at the outlet of the receiving hole 21. When the male plug 1 abuts against the stop blocks 23, the stop blocks 23 restrict the male plug 1 from detaching from the female plug 2 at the outlet. At this time, the elastic strips 22 reset, and the elastic strips 22 are located on the side of the connecting strip 12 close to the inlet, and the elastic strips 22 restrict the male plug 1 from detaching from the female plug 2 at the inlet.

[0043] Refer to Figure 1 and Figure 3 , when the male plug 1 is inserted into the female plug 2 from the inlet, the connecting strip 12 drives the elastic strips 22 to move, causing the elastic strips 22 to deform without restricting the movement of the male plug 1 until the male plug 1 abuts against the stop blocks 23. At this time, the elastic strips 22 reset, and the elastic strips 22 restrict the movement of the connecting strip 12, fixing the male plug 1 in the female plug 2.

[0044] Refer to Figure 3 , a convex block 24 is formed by stamping on the male plug 1. The convex block 24 is on the insertion path of the wiring part. When the wiring part is inserted into the male plug 1, the wiring part abuts against the first limiting strip 13 and the second limiting strip 14 until the wiring part abuts against the convex block 24, realizing the assembly of the wiring part and the male plug 1. A convex rib 241 is formed by stamping on the male plug 1. The convex rib 241 protrudes towards the connecting strip 12. When the wiring part abuts against the convex rib 241, the wiring part can abut against the first limiting strip 13.

[0045] The implementation principle of Example 1 is as follows: the staff first inserts the male plug 1 into the accommodating hole 21, allowing the connecting strip 12 to drive the elastic strip 22 to deform until the male plug 1 abuts against the stop block 23. At this time, the elastic strip 22 is reset, and the elastic strip 22 limits the movement of the male plug 1. Then the staff inserts the wiring part, allowing the wiring part to abut against the first limiting strip 13, the second limiting strip 14, the convex strip 241 and the convex block 24, so as to achieve mutual fixation of the wiring part and the male plug 1.

[0046] Example 2

[0047] Reference Figure 4 and Figure 5 The difference between this embodiment and the first embodiment is that two fixing springs 25 are fixedly connected to the female plug 2, and the fixing springs 25 have elastic deformation capability. The fixing springs 25 are deformed toward the male plug 1, and the fixing springs 25 can abut against the bending of the first limit strip 13 and the yield strip 131.

[0048] Reference Figure 6 The surface of the female plug 2 where the outlet is provided is provided with a placement groove 26 connected to the receiving hole 21, and a placement bar 261 is detachably connected in the placement groove 26, and a placement spring block 262 is fixedly connected to the surface of the placement bar 261, and the placement spring block 262 has elastic deformation capability. When the placement bar 261 is installed in the placement groove 26, the placement spring block 262 abuts against the fixed spring sheet 25, and at this time, the placement bar 261 drives the fixed spring sheet 25 to deform toward the direction of the male plug 1 through the placement spring block 262, so that the first limit bar 13 abuts against the wiring part, thereby improving the connection strength between the first limit bar 13 and the wiring part.

[0049] Reference Figure 6 The female plug 2 is provided with an operation hole 27 connected to the placement groove 26, and there are two operation holes 27. A U-shaped bar 28 is fixedly connected to the female plug 2, and the U-shaped bar 28 has elastic deformation capability. A groove 263 for inserting the U-shaped bar 28 is provided on the surface of the placement bar 261 away from the fixed spring sheet 25, and the groove 263 penetrates to the side of the placement bar 261. One end of the U-shaped bar 28 is located on the side of the placement bar 261 close to the first limiting bar 13, and the other end of the U-shaped bar 28 is located in the groove 263.

[0050] Reference Figure 6, when the placement bar 261 is inserted into the placement groove 26, the placement spring block 262 drives the fixed elastic piece 25 to deform in the direction of the male plug 1. At this time, the fixed elastic piece 25 drives one end of the U-shaped bar 28 close to the male plug 1 to tilt in the direction of the male plug 1, and the other end of the U-shaped bar 28 far from the male plug 1 tilts in the direction of the male plug 1. Since the U-shaped bar 28 is inserted into the groove 263, the U-shaped bar 28 drives the placement bar 261 to abut in the direction of the male plug 1, so that the placement bar 261 can be stably located in the placement groove 26. The staff drives the U-shaped bar 28 to move through the operation hole 27, so that the U-shaped bar 28 is separated from the groove 263, and the placement bar 261 is taken out from the placement groove 26.

[0051] Refer to Figure 5 and Figure 6 , a first stop bar 15 is integrally formed on the first limit bar 13, and the distance between the first stop bar 15 and the male plug 1 gradually decreases along the direction from the first limit bar 13 to the connecting bar 12. When the wiring part is inserted into the male plug 1, the wiring part drives the first limit bar 13 to deform in the direction away from the male plug 1, and the first limit bar 13 drives the first stop bar 15 to deform in the direction close to the male plug 1, strengthening the acting force of the first stop bar 15 on the wiring part, so that the wiring part can abut against the first stop bar 15 more stably. At this time, the deformation degree of the first stop bar 15 is greater than that of the second limit bar 14.

[0052] The implementation principle of Embodiment 2 is as follows: The staff first inserts the wiring part to make the wiring part abut against the first limit bar 13, the second limit bar 14 and the first stop bar 15. Then the staff slides the placement bar 261 to insert the U-shaped bar 28 into the groove 263, so that the U-shaped bar 28 restricts the movement of the placement bar 261 in the placement groove 26, and the placement spring block 262 drives the placement elastic piece to abut against the first limit bar 13, strengthening the restricting effect of the first limit bar 13 on the wiring part.
