Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an electrical connector. Background Art

[0002] An electrical connector is also often referred to as a circuit connector or an electronic connector, which can be used to bridge two electrical components on a circuit, so that current or signal can flow from one electrical component to another. Since electrical connectors are easy to be made into standardized components and have high electrical connection reliability, they are especially suitable for modular components.

[0003] Many electrical devices are controlled by a printed circuit board (PCB) and / or powered by a printed circuit board. For example, in an automobile, an electrical connector can be used to connect an LED lamp to a PCB to control and / or power the LED lamp. Such a connector may include electrical terminals configured to be crimped to a conductive wire (e.g., a wire of a cable connected to the LED lamp) and / or contact pins configured to be soldered to the PCB. There has been a trend to miniaturize components in many fields. This continuously requires electrical connectors with high signal density. In addition, improved vibration resistance is needed. For example, in automotive applications, it is desirable to prevent two mating connectors from becoming disengaged due to vibrations in the operating environment.

[0004] In the related art, an electrical connector generally includes a wire-end assembly (connector male head) and a board-end assembly (connector female socket). The wire-end assembly is used to be plugged into the board-end assembly to achieve electrical connection. Among them, the wire-end assembly and the board-end assembly usually need a position guarantee mechanism to ensure that the wire-end assembly and the board-end assembly can be stably connected and have certain vibration resistance. The existing position guarantee mechanism connects the wire-end assembly housing and the board-end assembly housing through a buckle. In some vibration environments, the buckle is easy to disengage, resulting in connection instability. Through multiple reinforcement structures, the buckle can be prevented from falling off, but it will greatly increase the volume of the electrical connector. Summary of the Invention

The term "and / or" as used herein includes any and all combinations of one or more of the related listed items.

[0036] Reference Figures 1 to 10 As shown, this utility model discloses an electrical connector 10, which includes a board-end component 12, a wire-end component 11, an elastic clamping structure 112, and a locking member 13. Among them, the board-end component 12 includes a board-end housing 121 with an opening 1212 on one side. A board-end terminal is arranged inside the board-end housing 121. On the side wall of the board-end housing 121, such as Figure 1 the upper wall surface in, there is a connection hole 1211. The connection hole 1211 is a rectangular hole, which communicates the inside and outside of the board-end housing 121, and the hole wall of the connection hole 1211 is a plane. The wire-end component 11 includes an extending end 111. The front end of the extending end 111 is a wire-end terminal 114. The front end of the extending end 111 is inserted into the board-end housing 121 through the opening 1212 of the board-end housing 121, so that the board-end terminal is cooperatively connected with the wire-end terminal 114 to realize the electrical connection between the board-end component 12 and the wire-end component 11, so as to realize the circulation of current and data information. An elastic clamping structure 112 is arranged on the upper side wall of the extending end 111. The elastic clamping structure 112 is arranged between the inner wall of the board-end housing 121 and the side wall of the wire-end extending end 111. When the extending end 111 is inserted into the wire-end housing, the inner wall of the wire-end housing applies an extrusion force to the elastic clamping structure 112, and the elastic clamping structure 112 simultaneously applies an elastic force to the inner wall of the board-end housing 121 and the extending end 111 of the wire-end component 11 to increase the connection strength between the extending end 111 and the board-end housing 121. At the same time, a part of the elastic clamping structure 112 is clamped into the connection hole 1211 to fix the relative positions of the board-end housing 121 and the wire-end component 11. A locking member 13 is provided corresponding to the elastic clamping structure 112. The locking member 13 includes an elastic support structure 131. The elastic support structure 131 is adapted to the elastic clamping structure 112, and the elastic support structure 131 applies an elastic support force to the elastic clamping structure 112 to increase the clamping force of the elastic clamping structure 112 clamped into the connection hole 1211.

[0037] Reference Figures 1 to 3As shown, the elastic snap - fit structure 112 includes an elastic cantilever 1121. The elastic cantilever 1121 extends backward from the front end of the protruding end 111 to the rear of the convex - line - end assembly 11. The elastic cantilever 1121 includes a fixed end 1122 and a cantilever end 1123. The fixed end 1122 is fixed to the front end of the protruding end 111, and the cantilever end 1123 extends backward to the outside of the opening 1212 of the board - end housing 121; the elastic cantilever 1121 bounces upward and can move downward by pressing. The elastic cantilever 1121 is a rigid member. Since the fixed end 1122 is fixed to the protruding end 111, when the cantilever end 1123 is pressed downward, the rigid cantilever end 1123 generates an upward elastic force. Inside the board - end housing 121, the cantilever end 1123 abuts against the inner wall of the board - end housing 121 upward, and the fixed end 1122 is fixed to the side wall of the line - end assembly 11, so that the line - end assembly 11 is tightly connected to the board - end assembly 12. On the upper wall of the elastic cantilever 1121, a positioning snap - convex 1124 protrudes. The positioning snap - convex 1124 is connected to the front end of the elastic cantilever 1121 through an inclined surface to reduce the resistance of the positioning snap - convex 1124 when it snaps into the connection hole 1211. When the protruding end 111 is inserted into the board - end housing 121, the positioning snap - convex 1124 snaps into the connection hole 1211, and the size of the positioning snap - convex 1124 is adapted to the connection hole 1211, so that the positioning snap - convex 1124 can accurately fix the relative position of the line - end assembly 11 and the board - end assembly 12.

[0038] Reference Figure 1 、 Figure 2 and Figure 7 As shown in, in one embodiment, the elastic cantilever 1121 further includes a limit stop rod 1125. The limit stop rod 1125 is connected to the elastic cantilever 1121. Pressing the limit stop rod 1125 can drive the elastic cantilever 1121 to move. The limit stop rod 1125 is inclined upward. At the opening 1212 of the board - end housing 121, the limit stop plate is inclined upward and its upper surface is arc - shaped. In the locked position, the limit stop rod 1125 abuts against the inner wall of the board - end housing 121, and the arc - shaped surface abuts against the edge at the opening 1212 of the board - end housing 121. When the protruding end 111 is inserted into the board - end housing 121, since the rear end of the arc - shaped limit stop rod 1125 is higher than the front end, therefore, the upper surface of the arc - shaped stop rod exerts a forward thrust on the board - end housing 121, making the board - end housing 121 tend to move forward relative to the protruding end 111. At this time, the positioning snap - convex 1124 contacts the hole wall of the connection hole 1211 and exerts a backward thrust on the connection hole 1211, so that the board - end housing 121 is tightly connected to the line - end protruding end 111.

[0039] Reference Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 and Figure 8As shown, the elastic cantilever 1121 includes at least two cantilevers. The two cantilevers are parallel to each other and spaced apart in the left-right direction. The positioning clamping protrusion 1124 connects two adjacent cantilevers. The elastic support structure 131 includes an elastic support arm 132. The gap between the two cantilevers is adapted to the outer diameter of the elastic support arm 132. The elastic support arm 132 is inserted between two adjacent cantilevers from the rear to the front. The front end of the elastic support arm 132 corresponds to the positioning clamping protrusion 1124. In the locked position, the front end of the elastic support arm 132 abuts against the lower end of the positioning clamping protrusion 1124, preventing the positioning clamping protrusion 1124 from moving downward, so that the positioning clamping protrusion 1124 can be kept inserted into the connection hole 1211 to ensure the relative position between the board end assembly 12 and the wire end assembly 11.

[0040] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the elastic support structure 131 further includes a locking clamping protrusion 136. The locking clamping protrusion 136 is provided at the front end of the elastic support arm 132. In the locked position, the locking clamping protrusion 136 corresponds to the connection hole 1211 and is inserted into the gap between the front end of the positioning clamping protrusion 1124 and the hole wall of the connection hole 1211. The elastic clamping structure 112 includes an elastic cantilever 1121 and strip-shaped sliders 133 located on the left and right sides of the elastic cantilever 1121. The sliders 133 and the elastic cantilever 1121 both extend in the front-rear direction and are parallel to each other. The number of elastic cantilevers 1121 is at least two and they are parallel to each other. An insertion channel is formed between the two elastic cantilevers 1121. The elastic support arm 132 is inserted into the insertion channel from the rear to the front until the front end of the elastic support arm 132 corresponds to the connection hole 1211. Since the elastic support arm 132 bulges upward in the direction from the rear to the front, in the locked position, the locking clamping protrusion 136 at the front end of the elastic support arm 132 moves to the position corresponding to the connection hole 1211 and is inserted into the gap between the hole wall of the connection hole 1211 and the positioning clamping protrusion 1124 from the bottom to the top, further increasing the connection strength between the elastic cantilever 1121 and the connection hole 1211.

[0041] Reference Figures 1 to 6As shown, the locking projection 136 includes a first plane 1361, a second plane 1362, and a third plane 1363 that are adjacent to each other in sequence. During the process of inserting the elastic support arm 132 between two adjacent cantilevers, the positioning projection 1124 contacts the first plane 1361, the second plane 1362, and the third plane 1363 in sequence. Transition surfaces are provided between the first plane 1361 and the second plane 1362 and between the second plane 1362 and the third plane 1363. On both sides of the elastic cantilever 1121 are chutes 1126, and between adjacent elastic cantilevers 1121 is an insertion channel, which is parallel to the chutes 1126. The locking member 13 includes an elastic support arm 132 in the middle and sliders 133 on both sides. The sliders 133 are correspondingly inserted into the chutes 1126, and the elastic support arm 132 is correspondingly inserted into the insertion channel. The elastic support arm 132 is inclined upward in the direction from back to front. During the insertion process, the first plane 1361 at the front end of the elastic support arm 132 first contacts the positioning projection 1124, and the positioning projection 1124 presses down the front end of the elastic support arm 132. As the insertion depth increases, the positioning projection 1124 crosses the first plane 1361 and contacts the second plane 1362 and gets stuck at the transition surface to indicate the insertion process. Then it crosses the second plane 1362 and contacts the third plane 1363, getting stuck again. At this time, the locking projection 136 is snapped into the connection hole 1211, and the connection is in place.

[0042] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the elastic clamping structure 112 is provided with a sliding groove 1126 in the front-rear direction. The locking member 13 is provided with a sliding block 133 corresponding to the sliding groove 1126. The front end of the sliding block 133 is provided with an outward barb 1331, and the barb 1331 corresponds to the front end of the sliding groove 1126 to prevent the locking member 13 from disengaging from the elastic clamping structure 112 backward. When the wire end assembly 11 is not inserted into the board end assembly 12, the locking member 13 does not need to be locked. At this time, to prevent the locking member 13 from falling, the locking member 13 is first inserted and connected to the elastic clamping structure 112. The locking member 13 includes sliding blocks 133 on both sides of the elastic support arm 132. The sliding blocks 133 slide into the sliding groove 1126 of the elastic clamping structure 112, and the length of the sliding blocks 133 is less than the length of the elastic support arm 132, so that the front end of the elastic support arm 132 is located in front of the front end of the sliding block 133. The front end of the sliding groove 1126 is located behind the positioning clamping protrusion 1124. Before the front end of the elastic support arm 132 contacts the rear end of the positioning clamping protrusion 1124, the barb 1331 of the sliding block 133 passes through the sliding groove 1126 and abuts against the front end of the sliding groove 1126, which can ensure that the locking member 13 does not disengage from the wire end assembly 11 before the elastic support arm 132 is clamped with the positioning clamping protrusion 1124. After the wire end assembly 11 is inserted and connected to the board end assembly 12, the locking member 13 is pushed forward again so that the locking clamping protrusion 136 of the locking member 13 is clamped between the positioning clamping protrusion 1124 and the hole wall of the connection hole 1211, playing a locking role, thereby improving the supporting performance of the elastic support arm 132 for the elastic cantilever 1121 and preventing the elastic cantilever 1121 from moving downward and disengaging from the connection hole 1211. To increase the connection stability between the wire end assembly 11 and the board end assembly 12.

[0043] Reference Figures 4 to 5 As shown, the side walls of the sliding block 133 and the elastic support arm 132 are both provided with reinforcing ribs 1332. The reinforcing ribs 1332 are strip-shaped ribs extending in the front-rear direction and are provided on the lower wall surfaces of the sliding block 133 and the elastic support arm 132 to increase the rigidity of the sliding block 133 and the elastic support arm 132. In some embodiments, the width of the rib on the lower surface of the elastic support arm 132 is greater than the width of the rib of the sliding block 133.

[0044] Reference Figure 6 and Figure 8 As shown, the locking member 13 further includes a support platform 134. The support platform 134 is correspondingly provided below the cantilever end 1123. In the locking position, the upper end of the support platform 134 abuts against the lower end of the cantilever end 1123. When the elastic support structure 131 includes a plurality of elastic cantilevers 1121, the number of support platforms 134 is multiple and corresponds to the elastic cantilevers 1121 one by one.

[0045] In some embodiments, the table surface of the support platform 134 is inclined forward from top to bottom, and the inclination angle of the lower wall surface of the cantilever end 1123 corresponds to the table surface of the support platform 134, so that in the locking position, the lower wall surface of the cantilever end 1123 fits with the table surface of the support platform 134.

[0046] Reference Figure 6 and Figure 8 As shown, the locking member 13 further includes a thrust baffle 135. The lower end of the thrust baffle 135 is connected to the support platform 134, and the front end of the thrust baffle 135 corresponds to the rear end of the cantilever end 1123. In the locked position, the surface of the thrust baffle 135 is in contact with the rear end surface of the cantilever end 1123. The thrust baffle 135 and the support platform 134 cooperate with each other to limit the movement of the cantilever end 1123.

[0047] Reference Figure 1 、 Figure 9 and Figure 10 As shown, the electrical connector 10 includes a wire-end assembly 11 and a board-end assembly 12. The wire-end assembly 11 and the board-end assembly 12 are connected by plugging. The wire-end assembly 11 is provided with wire-end terminals 114, and the board-end assembly 12 is provided with board-end terminals. When the wire-end assembly 11 and the board-end assembly 12 are plugged and connected, the board-end terminals and the wire-end terminals 114 are adaptively connected to achieve the electrical connection between the wire-end assembly 11 and the board-end assembly 12. In some embodiments, the wire-end assembly 11 includes a terminal fixing member 113 for fixing the positions of the wire-end terminals 114 to ensure accurate contact connection with the board-end terminals. The wire-end terminals 114 are arranged in rows at intervals and are divided into two rows in the up-down direction. The upper row of wire-end terminals 114 and the lower row of wire-end terminals 114 are arranged in a staggered manner. The terminal fixing member 113 includes a plurality of protrusions, and grooves are formed between adjacent protrusions. Among them, the protrusions are fixedly connected to the upper row of wire-end terminals 114 in a corresponding manner, and the grooves are fixedly connected to the lower row of terminals in a corresponding manner. The positions of the wire-end terminals 114 are accurately fixed by the terminal fixing member 113 to increase the plugging accuracy between the wire-end assembly 11 and the board-end assembly 12. At the same time, in a vibrating environment, the stability of the wire-end terminals 114 can be ensured, thereby ensuring the stability of the electrical connector 10.

[0048] In some embodiments, the terminal fixing member 113 can also be used to fix the board-end terminals to make the positions of the board-end terminals accurate, thereby increasing the connection stability and vibration resistance between the wire-end assembly 11 and the board-end assembly 12.
