[0031] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0032] Reference Figures 1 to 4 The on-board connector 100 according to a first aspect embodiment of the present invention includes:

[0033] The insulating housing 110 includes an outer shell 111 and a rear cover 112, which are detachably connected and form a cavity between the outer shell 111 and the rear cover 112; the cavity includes a first mounting cavity 113 and two second mounting cavities 114, with the first mounting cavity 113 located between the two second mounting cavities 114.

[0034] The signal terminal assembly 120 includes multiple signal terminal units 121, which are vertically stacked in sequence. Each signal terminal unit 121 includes seven terminals 1211 and a plastic layer 1212 formed by integrally encapsulating the seven terminals. The signal terminal assembly 120 is installed in the first mounting cavity 113.

[0035] The conductive terminal assembly 130 includes two conductive terminal units 131, which are respectively installed in two second mounting cavities 114.

[0036] Understandably, referring to Figure 2 The outer casing 111 has a "7"-shaped side profile. An internal cavity is formed between the outer casing 111 and the rear cover 112. This internal cavity is divided into a first mounting cavity 113 and two second mounting cavities 114. The first mounting cavity 113 is used to mount the signal terminal assembly 120, and the two second mounting cavities 114 are used to mount the two conductive terminal units 131, respectively. It should be noted that the "7"-shaped outer casing 111 can securely hold the signal terminal assembly 120 mounted in the first mounting cavity 113 and the conductive terminal units 131 mounted in the second mounting cavities 114, making the installation more stable and less prone to falling off.

[0037] Understandably, referring to Figure 3 Each signal terminal unit 121 consists of seven tightly integrated terminals 1211, and is covered by an integrally molded plastic layer 1212. Multiple signal terminal units 121 are vertically stacked to form a signal terminal assembly 120, which is installed in the first mounting cavity 113. It should be noted that there is no limitation on the number of terminals 1211 and signal terminal units 121. The number of terminals 1211 and signal terminal units 121 can be other numbers. In one embodiment, there are five signal terminal units 121, which are vertically stacked and tightly arranged to form the signal terminal assembly 120, which is installed in the first mounting cavity 113.

[0038] Understandably, referring to Figure 1 The outer shell 111 and the rear cover 112 are detachably connected, including snap-fit ​​connections, sliding connections, etc. In one embodiment, the outer shell 111 and the rear cover 112 are slidably connected, with the rear cover 112 sliding vertically to achieve a movable connection. Specifically, when the rear cover 112 slides upward vertically, the first protrusion 1121 is engaged in the first groove 1112, and the second protrusion 1122 is engaged in the second groove 1113, achieving a tight connection between the rear cover 112 and the outer shell 111; when the rear cover 112 slides downward vertically, the first protrusion 1121 is separated from the first groove 1112, and the second protrusion 1122 is separated from the second groove 1113, achieving separation between the rear cover 112 and the outer shell 111.

[0039] It is understood that the connector on the circuit board of this embodiment tightly integrates seven signal terminals and integrally encapsulates them with a plastic layer 1212 to form a signal terminal unit 121. Multiple signal terminal units 121 are stacked vertically in sequence to form a signal terminal assembly 120. The signal terminal assembly 120 has a small volume and is installed in the first mounting cavity 113 of the insulating housing 110, which can save space.

[0040] According to some embodiments of the present invention, the outer shell 111 is provided with two first mounting holes, and two conductive terminal units 131 pass through the first mounting holes and are installed in the corresponding second mounting cavities 114, so that the conductive terminal units 131 can be stably installed in the second mounting cavities 114.

[0041] According to some embodiments of the present invention, the conductive terminal unit 131 includes a first conductive part 1311 and a second conductive part 1313, and the first conductive part 1311 and the second conductive part 1313 are fixedly connected.

[0042] It is understood that the fixed connection method includes, but is not limited to, snap-fit ​​connection and threaded connection. In one embodiment, matching threads are provided on the first conductive part 1311 and the second conductive part 1313, and a tight connection is achieved by rotation. It should be noted that the first conductive part 1311 and the second conductive part 1313 can also be integrally formed.

[0043] According to some embodiments of the present invention, the first conductive part 1311 is provided with a second mounting hole 1312, and the second conductive part 1313 is provided with a connector 1314, which is fixedly installed in the second mounting hole 1312.

[0044] Understandably, referring to Figure 4 The connector 1314 and the second conductive part 1313 are integrated into one piece. The size of the connector 1314 matches the size of the second mounting hole 1312. The connector 1314 can be inserted into the second mounting hole 1312 to fix the first conductive part 1311 and the second conductive part 1313 together.

[0045] According to some embodiments of the present invention, a first buckle 1213 is provided on the plastic layer 1212 of the signal terminal unit 121, and the first buckles 1213 of multiple signal terminal units 121 are arranged sequentially to form a buckle unit.

[0046] Understandably, referring to Figure 3Each signal terminal unit 121 has a plastic layer 1212, and each plastic layer 1212 has a first latch 1213 at the same position. Since each signal terminal unit 121 is vertically stacked to form a signal terminal assembly 120, each first latch 1213 is also arranged to form a latch unit. In one embodiment, five first latches 1213 are arranged to form a latch unit, which is engaged in a first latching slot 1111.

[0047] According to some embodiments of the present invention, the outer shell 111 is provided with a first slot 1111, the first slot 1111 is located at the top of the first mounting cavity 113, and the first slot 1111 is engaged with the snap-fit ​​unit so that the signal terminal assembly 120 can be securely installed in the first mounting cavity 113.

[0048] Understandably, referring to Figure 2 The size of the first slot 1111 is not limited; it can be adjusted according to the size of the latching unit. With a fixed size for the first latch 1213, a larger number of first latches 1213 results in a larger latching unit and consequently, a larger first slot 1111. In other words, the size of the first slot 1111 should match the size of the latching unit so that the latching unit can be properly engaged within it.

[0049] According to some embodiments of the present invention, a first groove 1112 is provided on the outer shell 111, and a first protrusion 1121 is provided on the rear cover 112. The first groove 1112 and the first protrusion 1121 are engaged and connected, so that the outer shell 111 and the rear cover 112 can be connected more tightly.

[0050] According to some embodiments of the present invention, a second groove 1113 is provided on the outer shell 111, and a second protrusion 1122 is provided on the rear cover 112. The second groove 1113 and the second protrusion 1122 are engaged and connected.

[0051] Understandably, referring to Figure 2 The second protrusion 1122 is designed with an asymmetrical shape, narrower on one side and wider on the other. When the back cover 112 slides relative to the outer shell 111, the narrower side can more easily pass through the narrow gap between the outer shell 111 and the back cover 112, while the wider side acts as a stable lock after sliding into place, preventing the back cover 112 from accidentally slipping off. Specifically, when the back cover 112 begins to slide, the narrower side will enter the narrow gap first, and as the sliding continues, the wider side will gradually enter the narrow gap. Once the back cover 112 has fully slid into place, the wider part of the second protrusion 1122 will fit tightly with the corresponding part of the second groove 1113, forming a stable locking structure.

[0052] According to some embodiments of the present invention, a first heat dissipation hole 1114 is provided on the outer shell 111.

[0053] According to some embodiments of the present invention, a second heat dissipation hole 1123 is provided on the back cover 112.

[0054] Understandably, referring to Figure 2 By using evenly distributed heat dissipation holes on the outer casing 111 and the rear cover 112, natural convection of air inside and outside the insulating casing 110 is achieved. When heat is generated inside, it is quickly exchanged with the outside cool air through the heat dissipation holes, thereby reducing the internal temperature and preventing performance degradation or even damage caused by overheating. In addition, the design of the heat dissipation holes also takes into account the requirements of solderability. By precisely controlling the position, size and shape of the heat dissipation holes, not only can the problem of obstruction during the soldering process be avoided, but also good ventilation and heat dissipation conditions can be ensured in the soldering area.

[0055] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
