[0035] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0036] Reference Figures 1 to 6 The wire harness connector 100 according to a first aspect embodiment of the present invention includes:
[0037] The insulating housing 110 includes a main housing 111. The main housing 111 is provided with a signal terminal slot 112 and two conductive terminal slots 113. The signal terminal slot 112 is located between the two conductive terminal slots 113. The main housing 111 is provided with a first pin hole 114, a lock hole 115 and a pull strap hole 116.
[0038] Signal terminal assembly 120 is installed in signal terminal slot 112;
[0039] The conductive terminal assembly 130 includes two conductive terminal units 131, which are respectively installed in two conductive terminal slots 113;
[0040] The pin 140 includes a pin body 141, a fixing groove 142 is provided in the middle of the pin body 141, and insert arms 143 extend from both sides of the fixing groove 142 respectively; the pin 140 passes through the first pin hole 114 and is fixedly connected to the insulating shell 110; the fixing groove 142 engages with the signal terminal assembly 120; a cavity is formed between the insert arms 143 and the inner wall of the conductive terminal groove 113; the cavity limits and fixes the conductive terminal unit 131.
[0041] The unlocking component 150 includes a spring 153, a latch 151, and a pull strap 152. The spring 153 includes a fixed end and a movable end. The latch 151 includes a fastening part, a rotating part, a spring connecting part, and a pull strap connecting part. The fastening part is fastened to the insulating shell 110, the rotating part is rotatably connected to the insulating shell 110, the spring connecting part is fixedly connected to the fixed end of the spring 153, and the pull strap connecting part is fixedly connected to the pull strap 152. The movable end of the spring 153 is engaged in the lock hole 115. The pull strap passes through the pull strap hole 116 to lock the latch 151.
[0042] Understandably, referring to Figure 1 and Figure 3 Insert arms 143 extend from both sides of the fixing groove 142 in the pin 140, and the pin 140 passes through the first pin hole 114 and is fixedly connected to the insulating shell 110. Correspondingly, on the back side of the first pin hole 114, the insulating shell 110 is provided with two insertion arm 143 holes to accommodate the insertion arms 143 of the pin 140, so that the entire pin 140 is embedded in the insulating shell 110, achieving a stable connection.

[0044] Understandably, referring to Figure 6 Both the locking hole 115 and the pull strap hole 116 are located on the same side of the main housing 111 and are on the same axis. The locking hole 115 is used to fix the spring 153. When the spring 153 is subjected to pressure, it undergoes compression deformation, thereby driving the rotating part to rotate and ultimately separating the fastening part from the main housing 111.

When unlocking is required, the user can activate the unlocking mechanism by directly pressing the spring fixing part or the area near the pull strap connection part. When external force is applied, the spring 153 is compressed, causing elastic deformation, and the rotating part rotates at an angle. As the rotating part moves, the latching part gradually separates from the latching surface of the insulating housing 110, ultimately unlocking the device.
[0046] Understandably, referring to Figure 2By installing the signal terminal assembly 120 in the signal terminal slot 112 and the conductive terminal assembly 130 in the conductive terminal slot 113, and using the pin 141, fixing slot 142 and insert arm 143 of the pin 140 to fix the insulating shell 110, the signal terminal assembly 120 and the conductive terminal assembly 130 to the same location, the internal structure is compact and not easy to loosen, and the size is small. At the same time, an unlocking device is adopted, which uses the elasticity of the spring 153 to drive the unlocking, so that the wire harness connector 100 can be easily unlocked in a confined space.
[0047] According to some embodiments of the present invention, the signal terminal assembly 120 includes a plurality of signal terminal units 121, which are arranged in a stacked manner.
[0048] According to some embodiments of the present invention, each signal terminal unit 121 includes five horizontally closely arranged signal terminals 1211 and a plastic layer 1212 formed by integrally encapsulating the five signal terminals 1211.
[0049] Understandably, referring to Figure 4 In one embodiment, five signal terminals are arranged horizontally and closely, and the five signal terminals 1211 are integrally encapsulated to form a plastic layer 1212. Multiple signal terminal units 121 are arranged in a stacked manner to form a signal terminal assembly 120. It should be noted that the number of signal terminals 1211 in this embodiment is merely illustrative and not a limitation on the number of signal terminals 1211. In practical applications, the number of signal terminals can be adjusted according to specific needs, for example, it can be two, three, four, or any other arbitrary number of signal terminals. After several signal terminals are arranged horizontally and closely, an integral encapsulation is performed to form a plastic layer.
[0050] Understandably, referring to Figure 4 In one embodiment, five signal terminals 1211 constitute a signal terminal unit 121, and seven signal terminal units 121 are horizontally stacked to form a signal terminal assembly 120. It should be noted that the number of signal terminal units 121 is not limited here, and the number of signal terminal units can be adjusted according to actual needs. However, the number of signal terminal units 121 should match the number of slots in the signal terminal slots 112 and the fixing block 122 to achieve a stable connection.
[0051] According to some embodiments of the present invention, the signal terminal assembly 120 further includes a fixing block 122, which has a plurality of slots. Each signal terminal unit 121 is fixedly installed in each slot, so that the signal terminal unit 121 can be stably installed on the fixing block 122 and installed into the signal terminal slot 112.
[0052] According to some embodiments of the present invention, a first slot 117 is provided on the main housing 111, and the first slot 117 is located on the inner wall of the top of the signal terminal slot 112.
[0053] According to some embodiments of the present invention, a first buckle 1221 is provided on the fixing block 122, and the first buckle 1221 and the first slot 117 are connected.
[0054] Understandably, referring to Figure 3 and Figure 4 The main housing 111 has a first slot 117 on the inner top wall of the signal terminal slot 112, and a corresponding first buckle 1221 on the fixing block 122. A reliable connection is achieved through the engagement of the buckle and the slot. In one embodiment, two first slots 117 are symmetrically positioned on the inner wall of the signal terminal slot 112, and two symmetrically distributed first buckles 1221 are provided on the corresponding positions of the fixing block 122. This symmetrical snap-fit structure design allows the fixing block 122 to be evenly stressed, ensuring it is securely locked in the signal terminal slot 112, and also ensuring the accurate positioning and secure installation of the conductive terminal unit 131 in the conductive terminal slot 113.
[0055] According to some embodiments of the present invention, the inner wall of the conductive terminal groove 113 is provided with a mounting hole, and the conductive terminal unit 131 is installed in the conductive terminal groove 113 through the mounting hole. The mounting hole is used to position and fix the conductive terminal unit 131.
[0056] Understandably, referring to Figure 5 The inner diameter of the mounting hole should be smaller than the maximum outer diameter of the conductive terminal 1311 to ensure that the conductive terminal assembly 130 is fixedly positioned within the cavity formed by the conductive terminal slot 113 and the insert arm 143. Specifically, the inner diameter of the mounting hole is slightly smaller than the maximum outer diameter of the conductive terminal 1311, ensuring that the conductive terminal unit 131 can pass tightly through the mounting hole and be firmly fixed within the conductive terminal slot 113. After the conductive terminal unit 131 is installed in place, it forms an interference fit with the inner wall of the mounting hole, which, together with the closed cavity formed by the insert arm 143 structure, achieves the positioning and fixing of the conductive terminal assembly 130.
[0057] According to some embodiments of the present invention, the conductive terminal unit 131 includes a conductive terminal 1311 and a positioning pad 1312. The positioning pad 1312 is provided with a positioning hole 1313 to limit the range of motion of the elastic abutment 144 and prevent it from shifting or falling off.
[0058] According to some embodiments of the present invention, an elastic abutment 144 is provided on the insert arm 143 for abutting and fixing the conductive terminal 1311. The elastic abutment 144 passes through the positioning hole 1313 and abuts and fixes with the conductive terminal 1311.
[0059] Understandably, referring to Figure 5 The positioning pad 1312 and the elastic abutment 144 cooperate with each other. When the pin 140 is installed in place, the elastic abutment 144 abuts against the positioning hole 1313 of the positioning pad 1312, which restricts the range of motion of the elastic abutment 144 and prevents the pin 140 from shifting, so that the insulating shell, signal terminal assembly 120 and conductive terminal assembly 130 can be connected more securely.
[0060] According to some embodiments of the present invention, the main housing 111 of the insulating housing 110 is provided with a first connecting hole, and the latch 151 of the unlocking component 150 is provided with a second connecting hole. The connector passes through the first connecting hole and the second connecting hole to connect the main housing 111 and the latch 151.
[0061] Understandably, referring to Figure 6 The insulating shell 110 and the latch 151 are connected by a rotatable connection. In one embodiment, a bolt is passed through the first connecting hole and the second connecting hole to achieve a rotatable connection. It should be noted that the rotatable connection also includes ball joint hinge connection, magnetic rotatable connection, etc. In one example, a ball socket is provided on the main shell 111, and a ball head is provided on the latch 151. The ball head is embedded in the ball socket to achieve multi-degree-of-freedom rotation.
