Detailed Description

In order to make the technical solutions and advantages of the present invention clearer, the following will describe embodiments of the present invention in further detail with reference to the accompanying drawings.

First, the terms "upper", "top", "lower" and "bottom" of the orientation according to the embodiment of the present invention are defined as follows:

the socket related to the embodiment of the invention comprises a shell, wherein the shell further comprises: backseat and face lid, backseat inside have accommodation space, and this accommodation space is used for holding the plug bush subassembly, and the face lid is connected in order to seal this accommodation space with the backseat to, the face is covered and is had the jack, and the jack corresponds the intercommunication with the slot of plug bush subassembly.

With the directions of the face cover and the rear seat as references, the embodiment of the invention defines the direction of the face cover as "upper" or "top" and the direction of the rear seat as "lower" or "bottom".

The five-hole socket integrates a two-pole socket and a three-pole socket into a whole, and comprises: the shell, be located the inside L utmost point plug bush subassembly of shell, the plug bush subassembly of N utmost point and the plug bush subassembly of E utmost point. Wherein, the utmost point plug bush subassembly of L and the utmost point plug bush subassembly of N all include: the conductive connecting strip, the three-pole plug bush and the two-pole plug bush are respectively connected with two opposite sides of the conductive connecting strip. The dipolar plug bush and the tripolar plug bush all include: the clamping device comprises a first clamping arm, a second clamping arm and an elastic crank arm, wherein two ends of the elastic crank arm are respectively connected with one ends of the first clamping arm and the second clamping arm, so that the first clamping arm and the second clamping arm are matched to form a slot.

In the related art, the first and second clamp arms are closer to the conductive connection bar than the elastic crank arm, that is, the elastic crank arm is closer to the end of the socket housing. In order to make the socket smaller in size, the related art shortens the gap distance (simply referred to as pitch) between the three-pole socket and the two-pole socket as much as possible, for example, to 0 pitch.

In the embodiment of the present invention, the distance between the plug bushes may also be understood as the distance between the insertion holes.

However, when the gap distance between the three-pole plug bush and the two-pole plug bush is too short, the plug cannot be simultaneously inserted into the three-pole plug bush and the two-pole plug bush, which is not favorable for the efficient use of the five-hole socket. At present, in order to improve the product competitiveness and the applicability of the socket and enable the socket to conform to more use scenes, the volume of a socket shell needs to be as small as possible, and the distance between plug bushes needs to be as large as possible. However, in order to reduce the volume of the socket housing based on the current five-hole socket structure, the distance between the plug bushes must be increased, i.e. there is a conflict between the volume of the socket housing and the distance between the plug bushes that cannot be optimized simultaneously.

An embodiment of the present invention provides a sleeve assembly, as shown in fig. 1, including: the conductive connecting strip 1, the two-pole plug bush 21 and the three-pole plug bush 22 are arranged on the same plane, wherein the two-pole plug bush 21 and the three-pole plug bush 22 are respectively connected with two opposite sides of the conductive connecting strip 1.

In particular, the elastic crank arm 203 is closer to the conductive connection strip 1 than the first and second

gripper arms

The number of the two-pole plug bushes 21 and the three-pole plug bushes 22 in the plug bush assembly is one, two, three or more than three, correspondingly, the number of the two-hole + three-hole plug bush combinations 10 is also one, two, three or more than three, and when the number of the two-hole + three-hole plug bush combinations 10 is multiple (i.e., two or more than two), the multiple two-hole + three-hole plug bush combinations 10 are arranged at intervals along the length direction of the socket housing.

The socket assembly provided by the embodiment of the invention uses the elastic crank arm 203 to provide elasticity for the two-pole socket 21 and the three-pole socket 22, and uses the slot to be plugged with a plug. By arranging the elastic crank arm 203, which has no direct contact with the plug, toward the inside of the receptacle, the first and second holding

arms

201 and 202, which have direct contact with the plug, are arranged toward the outside of the receptacle, that is, when the sleeve assembly is used for the receptacle, the insertion groove formed by the first and second holding

arms

201 and 202 is closer to the end (i.e., edge) of the receptacle housing 3, and the elastic crank arm 203 is closer to the center of the housing 3. So set up, can utilize socket housing 3's inner space more rationally, under the prerequisite that does not influence plug bush subassembly basic function, effectively reduce socket housing 3's width, and then reduce socket housing 3's volume. Based on this advantage, when designing the interval between the three-pole socket 22 and the two-pole socket 21, the interval can be increased appropriately compared with the related art, so as to achieve the purpose of increasing the jack interval. This increased jack interval is compensated by the reduced width of socket shell 3 that this plug bush subassembly brought, can make socket shell 3's width compare prior art and keep unchangeable or lower, like this, can reach the purpose that makes jack interval increase and make 3 voluminous reductions of socket shell body simultaneously, is showing improvement socket adaptability and socket competitiveness.

The first gripper arm 201 is connected to the elastic crank arm 202 via a first end 2011; the first clamping arm 201 is connected with the conductive connecting strip 1 through the second end 2012; first end 2011 and second end 2012 are located the same one side of first centre gripping arm 201 to, first end 2011 is located the top of second end 2012, that is to say, first end 2011 is last, and second end 2012 is under, so set up, do benefit to make plug bush and electrically conductive connecting strip connect through the integrated into one piece mode, and do benefit to the structure of simplifying the plug bush subassembly.

In some possible implementations, the first clamping arm 201 of the two-pole socket 21 and the three-pole socket 22 has a flat structure, and further, the top of the first clamping arm 201 has a first bending portion, and the first bending portion is bent in a direction away from the slot.

When applied to a socket, the arrangement angles of the two-pole plug bush 21 and the three-pole plug bush 22 relative to the conductive connecting bar 1 are different, so that the arrangement angles of the first clamping arm 201, the second clamping arm 202 and the elastic crank arm 203 are different, and the axial direction of the first clamping arm 201 of the two-pole plug bush 21 is perpendicular to the axial direction of the conductive connecting bar 1 by the first clamping arm 201 as an example; the axial direction of the first holding arm 201 of the three-pole socket 22 forms an angle with the axial direction of the conductive connecting bar 1, for example, the angle is 45 ° to 60 °.

Further, the top of the second clamping arm 202 has a second bending portion, and the second bending portion is bent along a direction away from the slot. That is, the first bending portion and the second bending portion have opposite bending directions, and both the first bending portion and the second bending portion can provide structural reinforcement.

The wall thickness of the first groove 3221 corresponds to the wall thickness of the first sidewall 322.

The part of the first side wall 322 between the two adjacent groups of two-hole and three-hole plug bush combinations 10 is recessed inwards to form a first groove 3221, the first groove 3221 is located between the two adjacent groups of two-hole and three-hole plug bush combinations 10, the plug bush assemblies are prevented from being affected, and the space of the rear seat 32 is reasonably utilized. By arranging the first connecting piece 41 in the first groove 3221 instead of arranging the first connecting piece 41 on the outer side surface of the first side wall 322, the first connecting piece 41 can be prevented from occupying other spaces except the first side wall 322, which is beneficial to reducing the width of the socket housing 3, and further reducing the volume of the socket.

In some possible implementations, the outer side surface of the first side wall 322 of the rear seat 32 is in contact with the inner side surface of the second connecting member 42 facing the first side wall 322, so that the clamping force between the first connecting member 41 and the second connecting member 42 can be improved, and the reduction of the volume of the socket is facilitated.

Further, the bottom end of the second connecting member 42 has a chamfer to form an operating gap between the bottom end of the second connecting member 42 and the first side wall 322 of the rear seat 32, and the operating gap enables the fingers of the operator to pinch or hook the bottom end of the second connecting member 42 to apply an outward pulling force to the bottom end of the second connecting member 42, so as to release the clamping between the first connecting member 41 and the second connecting member 42, and facilitate the clamping.

In some possible implementations, as shown in fig. 13, the socket provided by the embodiment of the present invention further includes a fixing frame 5, and the fixing frame 5 has a receiving cavity for receiving the rear seat 32. The first side wall 322 of the rear seat 32 has a third connecting part 43, the side wall of the fixing frame 5 has a fourth connecting part 44, and the third connecting part 43 is connected to the fourth connecting part 44, so as to connect the rear seat 32 and the fixing frame 5.

For example, if the rear seat 32 of the socket is rectangular, the fixing frame 5 is a rectangular frame, and the fixing frame 5 can be attached to a wall-mounted bottom case, thereby fixing the socket to the wall.

In some possible implementations, as shown in fig. 12, a first portion of the first side wall 322 of the rear seat 32 between each two-hole insert 1001 and a second portion of the first side wall between each three-hole insert 1002 each have a third groove 3222, the third groove 3222 is recessed toward the receiving space of the rear seat 32, and a bottom wall of the third groove 3222 is connected to the third connecting member 43.

The third groove 3222 is formed by recessing the part of the first side wall 322 between the two-hole plug bush 1001 and the three-hole plug bush 1002 in any two-hole + three-hole plug bush combination 10 to the inner side, and the space of the rear seat 32 is reasonably utilized on the premise of avoiding influence on the plug bush assembly due to the position design of the third groove 3222. By arranging the third connecting element 43 in the third groove 3222 instead of arranging the third connecting element 43 on the outer side surface of the first side wall 322, the third connecting element 43 can be prevented from occupying other space outside the first side wall 322, which is beneficial to reducing the width of the housing 3 of the socket, and further reducing the volume of the socket.

In some possible implementations, the third connector 43 and the fourth connector 44 are connected in a snap-fit manner to facilitate assembly and disassembly, and for example, as shown in fig. 13, the third connector 43 includes: one elastic latch 431 and two first fixed latches 432 connect the elastic latch 431 with the bottom wall of the third groove 3222, and connect the two first fixed latches 432 with the first sidewalls 322 at two sides of the third groove 3222.

The elastic clamping block 431 is in a trapezoid block-shaped structure, the lower end of the elastic clamping block 431 is connected with the bottom wall of the third groove 3222, a gap is formed between the inner side surface of the elastic clamping block 431 facing the bottom wall of the third groove 3222 and the bottom wall of the third groove 3222, and the outer side surface of the elastic clamping block 431 away from the first side wall 322 is obliquely arranged to serve as a guide surface. The first fixing block 432 is a rectangular block, and a clamping groove is formed at the bottom of the first fixing block 432.

The fourth link 44 includes: the second fixing clamping block 442 is arranged in a second clamping hole formed in the side wall of the fixing frame 5 and connected with the side wall of the fixing frame 5, wherein the second clamping hole is configured to be clamped with the elastic clamping block 431, the structure of the second fixing clamping block 442 is matched with that of the clamping groove in the first fixing clamping block 432, and the second fixing clamping block 442 can be embedded into the clamping groove from bottom to top to realize clamping of the first fixing clamping block 432 and the second fixing clamping block 442.

When the fixing bracket is installed, the fixing bracket 5 penetrates through the rear seat 32 from bottom to top, the side wall of the fixing bracket 5 receives the abutting effect of the elastic clamping block 431 and moves upwards along the elastic clamping block 431, and the elastic clamping block 431 has elasticity, and the outer side surface of the elastic clamping block 431 is obliquely arranged (plays a role in guiding), so that the upward movement of the fixing bracket is more labor-saving. When the fixing frame 5 moves upward to the position where the second clamping hole is opposite to the elastic clamping block 431, the elastic clamping block 431 can wholly or partially enter the second clamping hole (for example, the upper part of the elastic clamping block 431 is located in the second clamping hole), and the elastic clamping block 431 is restored to the original position under the elastic action, so that the clamping connection between the elastic clamping block 431 and the second clamping hole of the fourth connecting piece 44 is realized.

Meanwhile, the second fixing latch 442 of the fourth connecting member 44 moves upward along with the fourth connecting member 44 until being inserted into the slot of the first fixing latch 432, so that the first fixing latch 432 and the second fixing latch 442 are fastened together.
