Connectors

Abstract

A connector comprises a housing, a locking member, two lever members and a pulling member. The locking member has a body arranged on the housing and extending in a left-right direction, and two locking arms extending forward from the two ends of the body in a front-to-back direction, each locking arm having a locking portion located at the front end, wherein the locking member has two pushed portions. The two lever members are pivotally arranged on the housing and each lever member has a pushing portion. When the pulling member is pulled backward, the two lever members are linked and the pushing portions of the two lever members push the two pushed portions of the locking member, thereby driving the locking portions of the two locking arms of the locking member to move downward. The present invention can avoid the deflection of the locking member due to its excessive size, which makes it impossible for the two locking arms to descend completely, thereby preventing the problem of incomplete unlocking or unlocking failure.

Description

Technical Field

[0001] The present invention relates to a connector, and in particular to a connector with a locking component. Background Art

[0002] Both U.S. Patent Publication No. US10547142B1 and Chinese Utility Model Publication No. CN211351144U disclose a connector comprising a housing, a locking member disposed on the housing, and a pull-to-unlock member for pressing against the locking member. The locking member comprises a transversely extending body and two locking arms extending forward from opposite ends of the body. When the pull-to-unlock member is pulled rearward, its downwardly protruding active portion presses against the middle section of the body, causing the body and the two locking arms to elastically descend, thereby unlocking the connector. However, when the connector is relatively wide, the longer body of the locking member is susceptible to bending during the unlocking process. This prevents the active portion of the pull-to-unlock member, which presses against the middle section of the body, from fully descending the two locking arms connected to the opposite ends of the body, resulting in incomplete or impossible unlocking.

In detail, the lower shell 11 of the housing 1 also has two snap holes 118 connected to the accommodating space 117 and located on the left and right sides, and a plurality of dovetail grooves 110 connected to the accommodating space 117. The fixing block 23 has two snap protrusions 231 snapped into the two snap holes 118, and a plurality of dovetail blocks 232 corresponding to the plurality of dovetail grooves 110. The snap holes 118 and the snap protrusions 231 cooperate to enable the fixing block 23 to be assembled to the lower shell 11, and the dovetail grooves 110 and the dovetail blocks 232 cooperate to enhance the holding force between the fixing block 23 and the lower shell 11 in the up and down direction D2. When the connector 100 is docked with a docking connector, the docking board 114 of the connector 100 is inserted into a metal shell (not shown) of the docking connector, and the circuit board 21 of the connector 100 is inserted into a plug-in slot (not shown) of the docking connector and mechanically and electrically contacts the terminals (not shown) in the plug-in slot.

[0102] See Figures 1 to 5 The locking member 3 is made of metal, for example, and comprises a fixing section 31 disposed on the housing 1, an elastic section 32 extending forward from the fixing section 31 along the front-to-back direction D1, and a locking section 33 connected to the elastic section 32. The fixing section 31 has two fixing portions 311 arranged side by side on the left and right sides. The elastic section 32 has two elastic portions 321 extending forward from the two fixing portions 311, respectively. Each fixing portion 311 has an inserting tab 311a extending forward, and a connecting tab 311b extending forward from the rear end of the inserting tab 311a and connected to the corresponding elastic portion 321. The connecting tab 311b has a through hole 311c formed therein. The lower shell 11 of the housing 1 has two slots 151 formed forward from the rear end surface 112 to respectively accommodate the two inserting tabs 311a, and two insertion holes 152 corresponding to the two through holes 311c. The upper shell 12 of the housing 1 has two inserting posts 153. The inserting piece 311a is inserted into the slot 151 facing forward, and the inserting post 153 is inserted into the insertion hole 152 through the through hole 311c, thereby firmly fixing the fixing section 31 of the locking member 3 to the housing 1.

[0103] See Figures 2 to 5The locking section 33 has a main body 331 connected to the elastic section 32 and extending along the left-right direction D3, and two locking arms 333 extending forward from the two ends of the main body 331. The locking section 33 also has two mating ends 332 located at the rear sections of the two locking arms 333. Each of the mating ends 332 has a recessed portion 332a, and an inclined portion 332b adjacent to the recessed portion 332a and extending forward and upward. In this embodiment, the inclined portion 332b has a first inclined surface 332c adjacent to the recessed portion 332a, and a second inclined surface 332d extending forward from the first inclined surface 332c. The slopes of the first inclined surface 332c and the second inclined surface 332d are different. It should be noted that in other embodiments, the first inclined surface 332c and the second inclined surface 332d can also be integrated into a single inclined surface, which is not limited to this embodiment. In addition, the recess 332a may be omitted in other embodiments and is not limited to this embodiment. Each locking arm 333 has a locking portion 333a at its front end. The locking portion 333a of each locking arm 333 is an upwardly extending hook structure. The locking portions 333a of the two locking arms 333 are disposed in the two extending cavities 113a extending from the accommodating cavity 113 to the docking plate 114. The elastic force provided by the elastic section 32 of the locking member 3 enables the locking member 3 to move up and down between a locked position and an unlocked position. In the locked position, the locking portions 333a of the two locking arms 333 of the locking member 3 extend upward from the docking plate 114 outside the two extended cavity portions 113a of the accommodating cavity 113 and can be snapped into the two locking holes (not shown) of the metal shell 1 of the docking connector, so that the connector 100 and the docking connector are locked to each other; in the unlocked position, the locking portions 333a of the two locking arms 333 of the locking member 3 sink downward into the two extended cavity portions 113a of the accommodating cavity 113 to escape from the two locking holes of the metal shell 1 of the docking connector, so that the connector 100 and the docking connector are unlocked from each other.

[0104] See Figures 2 to 4 and Figures 8 and 9The two lever members 4 are arranged in a left-right arrangement and are pivotally mounted on the housing 1. The two lever members 4 correspond to the two mating ends 332 on the two locking arms 333, respectively. Each lever member 4 has a rod body 41 extending generally along the left-right direction D3, and a shaft portion 42 formed on the rod body 41 and pivotally connected to the housing 1. The rod body 41 has a first end 411 located on the inside and a second end 412 located on the outside, a driven portion 411a located on the first end 411, and a protrusion 412a located on the second end 412 and protruding downward to mate with the concave portion 332a of the corresponding mating end 332. The housing 1 has an axial hole 16 corresponding to the pivotal connection to the shaft portion 42. In this embodiment, each of the lever members 4 forms the shaft portion 42 by protruding upward and downward from the rod body 41. The housing 1 has four axial holes 16, and two of the four axial holes 16 form two groups. The two axial holes 16 in each group of axial holes 16 are distributed up and down and formed in the upper shell 12 and the lower shell 11 respectively. The two groups of axial holes 16 respectively accommodate the shaft portions 42 of the two lever members 4 so that the two lever members 4 can pivot relative to the housing 1.

[0105] The pulling member 5 includes a frame 51 disposed within the housing 1 and a pull strap 52 connected to the frame 51. The frame 51 has a front rod 511 located within the accommodating cavity 113, a rear rod 512 located outside the accommodating cavity 113, two side rods 513 connected between the front rod 511 and the rear rod 512, and two driving portions 514 formed on the outer sides of the two side rods 513 adjacent to the front rod 511 and respectively linked to the driven portions 411a of the two lever members 4. The lower housing 11 also has two sliding slots 119 extending forward and backward and arranged side by side. The two sliding slots 119 extend rearward from the accommodating cavity 113. Each of the side rods 513 of the frame 51 of the pulling member 5 has a sliding block 513a protruding downward and extending along the front-to-back direction D1. The sliding blocks 513 a of the two side rods 513 are slidably disposed in the two sliding slots 119 , thereby enabling the frame 51 of the pulling member 5 to stably move forward and backward relative to the housing 1 .

[0106] In this embodiment, each driving portion 514 of the pulling member 5 has a groove 514a, and each driven portion 411a of the lever member 4 has a protrusion 411b that is relatively rotatably disposed within the groove 514a of the driving portion 514. The engagement of the groove 514a with the protrusion 411b enables the two lever members 4 to be linked to the pulling member 5. However, it should be noted that the driving portion 514 of the pulling member 5 and the driven portions 411a of the two lever members 4 may also have other matching structures that can achieve a linked action. For example, each driving portion 514 of the pulling member 5 may also have a protrusion structure, and each driven portion 411a of the lever member 4 may also have a groove structure that matches the protrusion structure. Therefore, the present invention should not be limited to this embodiment.

[0107] The front end of the pull strap 52 is rotatably mounted on the rear rod 512 of the frame 51 , and the rear end of the pull strap 52 is wider for the user to hold and pull.

[0108] See Figures 10 and 11 When the pulling member 5 is pulled backward, the driving portion 514 of the pulling member 5 cooperates with the follower portions 411a of the two lever members 4, thereby linking the first ends 411 of the two lever members 4 to move backward and the second ends 412 to move forward, and causing the protrusions 412a of the two lever members 4 to disengage from the recesses 332a of the two mating ends 332, and pushing the inclined portions 332b of the two mating ends 332 on the two locking arms 333 forward, so that the locking member 3 moves from the locked position to the unlocked position, thereby driving the locking portions 333a of the two locking arms 333 of the locking member 3 to move downward, thereby unlocking the connector 100 and the docking connector.

[0109] It should be noted that, in this embodiment, the protrusions 412a of the two lever members 4 serve as the two pushing portions, and the inclined portions 332b of the two mating ends 332 on the latch arm 333 of the latch member 3 serve as the two pushed portions. However, in other embodiments, the inclined portions 332b of the two mating ends 332 of the latch member 3 (the two pushed portions) may also be constructed at other positions on the left and right sides of the latch member 3. For example, in a variant embodiment, the inclined portions 332b of the two mating ends 332 of the latch member 3 (the two pushed portions) may also be constructed at other positions on the left and right sides of the latch member 3. Figure 12 The inclined surface portions 332 b (the two pushed portions) of the two mating end portions 332 of the locking member 3 may also be constructed on the left and right ends of the main body 331 of the locking member 3 .

[0110] In summary, the present invention can prevent the locking member 3 from being bent due to its excessive length, which causes the two locking arms 333 to be unable to descend completely, by directly interacting with the two pushed portions 332b of the locking member 3 through the two lever members 4 linked by the pulling member 5, thereby preventing the problem of incomplete or impossible unlocking between the connector 100 and the docking connector.

[0111] However, the above is merely an embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. All simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the patent of the present invention.
