[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the connector terminal block of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0035] Please refer to Figures 1-7 A connector socket, comprising:
[0036] The insulator 100 includes, from top to bottom, an upper seat 110, a connecting seat 120, and a lower seat 130. The insulator 100 has a plurality of vertically connected mounting holes 140. The mounting holes 140 include an upper channel 141 formed in the upper seat 110, a connecting channel 142 formed in the connecting seat 120, and a lower channel 143 formed in the lower seat 130. The upper channel 141 and the lower channel 143 open to the same side. The side wall of the connecting seat 120 has a plurality of glue injection holes 121 that communicate with the connecting channel 142. The inner side of the upper channel 141 is provided with a first nut groove 144, and the inner side of the lower channel 143 is provided with a second nut groove 145.
[0037] A conductive metal busbar 200 is disposed in a mounting hole 140. The conductive metal busbar 200 has a first connection hole 210123 exposed from the side opening of the upper channel 141 and a second connection hole 220123 exposed from the side opening of the lower channel 143.
[0038] The connecting nut 300 includes a first nut disposed in a first nut groove 144 and a second nut disposed in a second nut groove 145;
[0039] The adhesive layer 400 is injected into the connection channel 142 through the injection hole 121 to connect the conductive metal busbar 200 and the insulator 100.
[0040] The insulator 100 uses a mounting hole 140 with vertical conduction, and the conductive metal busbar 200 does not require a 7-shaped bend, making processing convenient and simple. Both the upper channel 141 and the lower channel 143 have openings on the side of the groove. At the same time, the conductive metal busbar 200 has a first connecting hole 210123 and a second connecting hole 220123 that pass through the side, so that it can be fixed with the inner connecting nut 300. The connection through the connecting nut 300 is stable and has high connection strength. Adhesive is injected into the connecting channel 142 through the injection hole 121 to form an adhesive layer 400, which improves the stability of the connection and the sealing performance.
[0041] Please refer to Figure 2 and Figure 5 The mounting hole 140 includes a left hole group 146 on the left and a right hole group 147 on the right. A connecting channel 142 obliquely connects an upper channel 141 and a lower channel 143. The connecting channel 142 in the left hole group 146 is obliquely tilted to the left, and the connecting channel 142 in the right hole group 147 is obliquely tilted to the right. The conductive metal busbar 200 is adapted to the mounting hole 140. This arrangement ensures that the lower ends of the conductive metal busbar 200 in the left hole group 146 and the lower ends of the conductive metal busbar 200 in the right hole group 147 are far apart, increasing the safety distance and preventing short circuits.
[0042] Please refer to Figure 1 , Figure 2 and Figure 5 There is an upper isolation groove 113 between adjacent upper channels 141, and a lower isolation groove 132 between adjacent lower channels 143. The upper isolation groove 113 and the lower isolation groove 132 increase the electrical safety between adjacent conductive metal bars 200 and adapt to high voltage conditions.
[0043] Please refer to Figure 1 The outer wall of the connector 120 has several connecting lugs 122, and each connecting lug 122 has a connecting hole 123. The connecting lugs 122 are provided to facilitate the connection of the connector terminal block to other external components by connecting screws or bolts.
[0044] Please refer to Figure 1 The outer wall of the connector 120 also extends a positioning lug 124, which has a downwardly extending positioning post 125. The positioning post 125 is used for pre-positioning, making installation more convenient.
[0045] Please refer to Figures 1-3 The connecting seat 120 has an upper sealing ring 500 at the upper part of the connecting lug 122 and a lower sealing ring 600 at the lower part. The sealing rings improve the sealing performance.
[0046] Please refer to Figure 1 , Figure 2 and Figure 4 The upper side wall of the connecting seat 120 is provided with an upper mounting groove 111, in which the upper sealing ring 500 is disposed; the lower side wall of the connecting seat 120 is provided with a lower mounting groove 131, in which the lower sealing ring 600 is disposed. The axial movement of the sealing ring is restricted by the mounting grooves to ensure the effectiveness of the sealing ring.
[0047] Please refer to Figure 1 , Figure 2 and Figure 4 The upper mounting groove 111 extends axially with several limiting grooves 112, and the upper sealing ring 500 has limiting protrusions 510 extending into the limiting grooves 112. The limiting grooves 112 and the limiting protrusions 510 prevent the upper sealing ring 500 from rotating or moving.
[0048] Please refer to Figure 1 , Figure 2 and Figure 4 The connecting seat 120 has several limiting posts 126 extending axially downward, and the lower sealing ring 600 is provided with limiting holes 610 that are adapted to the limiting posts 126. The lower sealing ring 600 is prevented from rotating by the cooperation of the limiting posts 126 and the limiting holes 610.
[0049] Preferably, a sealing adhesive layer is provided between the upper sealing ring 500 and the lower sealing ring 600 and the connecting seat 120. The sealing performance is further improved by the sealing adhesive layer.
[0050] Preferably, the conductive metal busbar 200 is a copper busbar.
[0051] Preferably, the adhesive layer 400 is a high-temperature resistant adhesive.
[0052] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0053] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
[0054] In summary, the connector terminal block provided by this utility model features an insulator with vertically connected mounting holes, eliminating the need for a 7-shaped bend in the conductive metal busbar, thus simplifying processing. Both the upper and lower channels have side openings, and a first and second connecting hole are provided on the conductive metal busbar to allow for fixation with an inner connecting nut. This connection via the connecting nut ensures stability and high strength. Adhesive is injected into the connecting channel through the injection hole to form an adhesive layer, improving both connection stability and sealing performance.
