Description

Technical Field

[0001] This utility model relates to the field of mechanical and electronic engineering, and more specifically to a connector. Background Technology

[0002] Connector assemblies are devices used to connect two active devices to transmit current or signals. Connector assemblies simplify the assembly and mass production processes of electronic products. They are easy to maintain; if an electronic component fails, it can be quickly replaced when a connector assembly is installed. With technological advancements, electronic products equipped with connector assemblies can have their electronic components updated, replacing older, higher-performance components, facilitating upgrades. Connector assemblies also enhance the flexibility of product design when designing and integrating new products and when assembling systems from electronic components.

[0037] See Figures 1 to 9 The present invention discloses a connector 1000, which includes a housing 100 and an operating element 200.

[0038] The housing 100 is provided with a channel 110 extending in the longitudinal direction DL and a mounting member 120 disposed around the channel 110 on the outside of the channel 110. The mounting member 120 is provided with a stop groove 1211 extending in the longitudinal direction DL on its opposite side wall 121. The end wall 12111 of the stop groove 1211 opposite to the inlet 111 of the channel 110 is configured to be inclined relative to the longitudinal direction DL (see [link]). Figure 2 , 3 6 and 7).

[0039] The operating component 200 includes two operating arms 210 rotatably mounted on opposite sidewalls 121 of the mounting component 120 (see [link]). Figure 1 , 5 (6) and a connecting arm 220 connected between the two operating arms 210 and directly operated by the user. The user operates the connecting arm 220 to rotate the operating member 200 between a first position and a second position. The operating arm 210 has a protruding rib 211 on its side facing the mounting member 120, one end 2111 of which is configured to have an inclined end face 21111 (see 6). Figure 5 and 7 When the operating member 200 is in the first position, the protruding rib 211 is accommodated in the stop groove 1211 such that the inclined end face 21111 interferes with the end wall 12111 (see...). Figure 6 For clarity Figure 6 (The end face 21111 is not marked) to prevent the operating member 200 from moving along the first direction R1 (although) Figure 1 The first direction R1 is shown as clockwise, but those skilled in the art should understand that the present invention is not limited thereto. In other embodiments according to the present invention, the first direction R1 can also be counterclockwise. Rotating away from the first position, that is, the interference fit between the inclined end face 21111 and the end wall 12111 provides a large holding force, so that the operating arm 210 is held in the first position in preparation for the mating housing 300 to be assembled into the housing 100 as described below. Therefore, this state in which the operating arm 210 of the connector 1000 is held in the first position is also called the "pre-assembled state". Accordingly, the holding force provided by the interference fit between the end face 21111 and the end wall 12111 can be changed by changing the inclination angle of the end face 21111. For example, see... Figure 10When the inclined end face 21111 interferes with the end wall 12111 (not shown in the figure for clarity), the normal N of the inclined end face 21111 is configured to be in the direction of the tangent of the arc trajectory S along which the inclined end face 21111 rotates with the operating arm 210 (i.e., the normal N is also the tangent of the arc trajectory S). Therefore, the normal of the end wall 12111 (not shown in the figure for clarity) that interferes with the end face 21111 is also in the direction of the tangent of the arc trajectory S, which makes the holding force have a maximum value.

[0040] Because the connector 1000 is held in a pre-assembled state by the large holding force provided by the interference fit, the connector 1000 can be assembled on the spot. This simplifies the steps of assembling the connector in the prior art by first setting the connector in a pre-assembled state and then assembling it. It also overcomes the shortcomings of the existing connectors, which provide a small holding force and cannot reliably keep the connector in a pre-assembled state, and greatly improves the assembly efficiency of the connector.

[0041] See Figure 1 , 5 And 6, the operating arm 210 is also provided with: a flexible arm 212, and the protruding rib 211 is provided on the flexible arm 212 (see 6). Figure 5 This causes the other end 2112 of the protruding rib 211 to be close to the free end 2121 of the elastic arm 212. When the operating member 200 is in the first position, the elastic arm 212 and the protruding rib 211 are parallel to the longitudinal direction DL. When the operating member 200 is in the second position, the elastic arm 212 and the protruding rib 211 are perpendicular to the longitudinal direction DL, and the free end 2121 of the elastic arm 212 is close to the free end 2121 of the elastic arm 212. Figure 5 The middle finger points upwards (this situation is not shown in the diagram for simplicity). See also Figure 5 The elastic arm 212 is provided with a through hole 2122. One side wall 21221 of the through hole 2122 is coplanar with the inclined end face 21111, so that the user can easily observe the interference fit between the end face 21111 and the end wall 12111 through the through hole 2122.

[0042] See Figure 5 and 8 The operating arm 210 has a protruding stop 214 on the side opposite to the free end 2121 of the elastic arm 212. When the operating member 200 is in the first position, the stop 214 abuts against the side of the mounting member 120 opposite to the entrance 111 of the channel 110 to prevent the operating member 200 from rotating away from the first position in the second direction R2 (i.e., counterclockwise) opposite to the first direction R1, thereby limiting the operating member 200.

[0043] See Figures 1 to 3The mounting member 120 has a rotating shaft 1213 extending in the transverse direction DT, which is orthogonal to the longitudinal direction DL, on its opposite side wall. The operating arm 210 has a shaft hole 215 suitable for rotatably mounting the rotating shaft 1213 therein. The rotating shaft 1213 has a first tenon 12131 and a second tenon 12132 on its radially opposite sides.

[0044] See Figure 1 and 9 The shaft hole 215 is provided with a first boss 2151 and a second boss 2152 that are radially opposite each other. When the operating member 200 is in the first position, the first tenon 12131 abuts against the first boss 2151 and the second tenon 12132 abuts against the second boss 2152 to prevent the operating member 200 from rotating away from the first position along the second direction R2. When the operating member 200 rotates along the first direction R1 to and is in the second position, the first tenon 12131 abuts against the second boss 2152 and the second tenon 12132 abuts against the first boss 2151 to prevent the operating member 200 from rotating further along the first direction R1, thereby limiting the operation member 200.

[0045] See also Figure 9 The shaft hole 215 has a hole wall 2153 on the side of the first boss 2151 and the second boss 2152 facing the mounting member 120, which facilitates the movement of the first tenon 12131 and the second tenon 12132 thereon. The hole wall 2153 has an assembly opening 21531 that matches the shape of the rotating shaft 1213, the first tenon 12131 and the second tenon 12132 (see Figure 5 This facilitates the mounting of the operating arm 210 onto the rotating shaft 1213 via the mounting port 21531. The structural arrangement of the housing 100 and the operating member 200 according to the embodiment of the present invention greatly simplifies the assembly between the housing 100 and the operating member 200, which is beneficial for the miniaturization and integrated application of the connector 1000.

[0046] See Figure 1 , 2 In addition to 4, the connector 1000 further includes: a mating housing 300 having an unlocking ridge 310 extending in the longitudinal direction DL on its side wall 301, the unlocking ridge 310 being configured to abut against the other end 2112 of the rib 211 when the mating housing 300 is inserted into the housing 100 in the longitudinal direction DL, causing the rib 211 to deflect in the transverse direction DT orthogonal to the longitudinal direction DL and disengage from the stop groove 1211 (see 4). Figure 7The operating member 200 is unlocked, at which point the inclined end face 21111 and the end wall 12111 are no longer in interference engagement and there is no longer a holding force to keep the operating arm 210 in the first position, so that the operating member 200 can rotate away from the first position along the first direction R1, so that the connector 1000 is no longer in the pre-assembled state.

[0047] See Figure 4 and 7 The unlocking ridge 310 has one end 311 facing the rib 211 that is tapered and has a raised portion 3111. The other end 2112 of the rib 211 is configured as a hook that can interfere with the raised portion 3111 to prevent the mating housing 300 inserted into the housing 100 from moving along the insertion direction (i.e., due to user misoperation) along the insertion direction. Figure 7 The direction opposite to the longitudinal direction DL (i.e., Figure 7 The connector detaches from the housing 100 along the longitudinal direction (DL in the rearward direction), further improving the reliability of the connection and the assembly efficiency of the connector 1000.

[0048] See Figure 4 The mating housing 300 is further provided with guide posts 320 extending in a transverse direction DT orthogonal to the longitudinal direction DL on its side wall, and the mounting member 120 is further provided with guide grooves 1212 extending in the longitudinal direction DL on its opposite side wall (see Figure 2 and 3 The guide post 320 is configured to move in the guide groove 1212 when the mating housing 300 is inserted into the housing 100 in the longitudinal direction DL, thereby defining the trajectory of the displacement of the mating housing 300 relative to the housing 10 in the longitudinal direction DL, avoiding the mating housing 300 being inserted into the housing 10 with deviation relative to the housing 10 and the resulting unreliable connection between the mating housing 300 and the housing 10.

[0049] See Figure 1 , 5 In addition to the above, the operating arm 210 is also provided with a limiting groove 213, which is arc-shaped and has a first end 2131 and a second end 2132. The guide post 320 is configured to move in the limiting groove 213 when the mating housing 300 is inserted into the housing 100 in the longitudinal direction DL. At the same time, the operating member 200 rotates in the first direction R1, such that when the operating member 200 is in the first position, the guide post 320 is located at the first end 2131 and the mating housing 300 begins to be inserted into the housing 100. When the operating member 200 rotates in the first direction R1 to the second position, the guide post 320 is located at the second end 2132 and the mating housing 300 is fully inserted into the housing 100, thereby completing the assembly of the connector 1000.

[0050] See Figures 1 to 4 6. The mounting member 120 is provided with a flange 122 near the entrance 111 of the channel 110. The mating housing 300 is provided with a mating flange 330 at its end opposite to the housing 100. When the mating housing 300 is fully inserted into the housing 100, the mating flange 330 abuts against the flange 122 to prevent the mating housing 300 from being over-inserted into the housing 100 and to limit the mating housing 300. At least one of the guide groove 1212 and the stop groove 1211 extends to the flange 122, thereby facilitating the movement and timely operation of the guide post 320 in the guide groove 1212 when the mating housing 300 begins to be inserted into the housing 100 and / or facilitating the movement and timely operation of the unlocking ridge 310 in the stop groove 1211 when the mating housing 300 begins to be inserted into the housing 100.

[0051] See Figure 4 The mating housing 300 has a guide ridge 340 extending in the longitudinal direction DL on at least one of its top and bottom walls, and the mounting member 120 has a corresponding ridge groove 123 extending in the longitudinal direction DL on at least one of its top and bottom walls (see...). Figure 3 This allows the guide ridge 340 to move in the ridge groove 123 when the mating housing 300 is inserted into the housing 100 in the longitudinal direction DL, thereby further defining the trajectory of the displacement of the mating housing 300 relative to the housing 100 in the longitudinal direction DL, avoiding the mating housing 300 being inserted into the housing 100 in a deviated manner relative to the housing 10 and the resulting unreliable connection between the mating housing 300 and the housing 10.

[0052] As described above, the structural arrangement of the housing 100 and mating housing 300 according to the embodiments of the present invention greatly simplifies the assembly between the housing 100 and the mating housing 300, which is beneficial to the miniaturization and integrated application of the connector 1000.
