Description

[Technical Field]

[0001] This utility model relates to a pickup cover for an electrical connector. [Background Technology]

[0002] For prior art, please refer to patent CN113054504B, which discloses an electrical connector with a pickup cover. To ensure the pickup cover can be securely fastened to the connector, multiple latches extend downwards from the outer periphery of the pickup cover. The side wall of the connector's base has multiple slots that mate with the latches. Due to structural limitations, this type of latch cannot achieve a large holding force. Therefore, when the number of latches is small, the holding stability is poor. However, if the number of latches is large, alignment between the pickup cover and the base becomes difficult during mating.

[0003] Therefore, it is necessary to provide an improved pickup cover to solve the above problems. [Utility Model Content]

[0004] The main purpose of this invention is to provide a pickup cover that is easy to hold and has good holding performance.

[0006] Preferably, the latching arm includes a connecting portion integrally connected to the corresponding end wall and an upwardly extending operating portion, wherein the upper surface of the operating portion is lower than the upper surface of the substrate.

[0007] Preferably, the connecting parts are connected to both sides of the buckle arm.

[0008] Preferably, the slot is formed by recessing upward from the lower surface of the insulator.

[0009] Preferably, the two ends of the insulator extend outward beyond the corresponding end walls, and the lower surface of the end walls abuts against the upper surface of the insulator.

[0010] Preferably, the latching arm is disposed adjacent to the end face of the insulator.

[0011] Preferably, the pickup cover includes a plurality of stop plates extending downward from the two side walls respectively, the stop plates covering the outer sides of the two sides of the insulator.

[0012] Preferably, the thickness of the stop piece is less than the thickness of the sidewall, and the lower surface portion of the sidewall abuts against the upper surface of the insulator.

[0013] Preferably, the insulator includes positioning posts disposed adjacent to its two ends, the positioning posts extending downward from the lower surface of the insulator.

[0014] To solve the above technical problems, the present invention can adopt the following technical solution: a pickup cover for an electrical connector, the pickup cover including a longitudinally elongated substrate, end walls located at both ends of the longitudinal length of the substrate, side walls located on both sides of the substrate, and a latching arm connected to each of the end walls and spaced apart from the end walls, the latching arm including a latching head extending downward beyond the lower surface of the end wall and an operating part extending upward.

[0015] Preferably, each of the sidewalls extends downward to form a plurality of stop pieces, the thickness of the stop pieces being less than the thickness of the sidewall, and the outer surface of the sidewall being coplanar with the outer surface of the stop pieces.

Detailed Implementation Methods

[0035] See Figures 1-4 As shown, the electrical connector assembly 100 of this utility model includes an electrical connector 10 and a pickup cover 20. The electrical connector 10 can be used to electrically connect a chip (not shown) to a circuit board (not shown). The electrical connector 10 includes an insulator 11 and a plurality of terminals 12. This embodiment only schematically shows two rows of partial terminals and does not show all the terminals. However, in actual products, the insulator 11 can be provided with hundreds or thousands of terminals 12 arranged in a matrix. The pickup cover 20 is placed on the electrical connector 10, which can prevent dust, water, etc. from entering the electrical connector 10. The electrical connector assembly 100 can also be moved by using a jig to act on the pickup cover 20. In this embodiment, the pickup cover 20 includes a base plate 21, two end walls 22 extending downward from both ends of the base plate 21 in the lateral direction, two side walls 23 extending downward from both sides of the base plate 21 in the front-rear direction and connecting the two end walls 22, and a latching arm 24 disposed on each end wall 22. Each latching arm 24 includes a latching head 241 disposed at its lower end and an operating part 242 disposed at its upper end. Preferably, the insulator 11 is plate-shaped and has a latching groove 111. The latching groove 111 is recessed upward from the lower surface of both ends of the insulator 11 in the lateral direction and penetrates the corresponding end faces of the insulator 11 at both ends. That is, the latching groove 111 is downward and open to both ends to facilitate the latching head 241 entering the latching groove 111 during latching.

[0036] Further integration Figures 5-6In this embodiment, to facilitate the removal of the latch head 241 from the slot 111 when operating the operating part 242, such as along... Figure 6 Pressing the operating part 242 inward in the direction of arrow M1 causes the latching head 242 to exit the slot 111 in the direction of arrow M2. The latching arm 24 is connected to the corresponding end wall 22 via two connecting parts 243 located on both sides. The latching arm 24 can be spaced apart from the end wall 22 as needed. The operating part 242 has sufficient space to deform towards the end wall 22, thereby causing the latching head 242 to deform outward and exit the slot 111 under the action of the operating part 242. Preferably, in this embodiment, the latching head 242 is a hook. In addition, in this example, the upper surface of the substrate 21 of the pickup cover 20 is preferably a smooth surface, which facilitates the adsorption of the pickup cover 20 by the fixture to achieve the movement of the electrical connector 10. To prevent the operating part 242 from interfering with the fixture when operating the fixture, the upper surface of the operating part 242 is lower than the upper surface of the substrate 21.

[0037] See Figure 1 and Figure 5 In this embodiment, the two ends of the insulator 11 extend laterally and exceed the corresponding end walls 22. That is, the two ends of the insulator 11 are exposed outside the pickup cover 20. When the pickup cover 20 is placed on the insulator 11, the lower surface of the end wall 22 abuts against the upper surface of the insulator 11, and the inner surface of the latching arm 24 is disposed close to the end face of the insulator 11. That is, the latching arm 24 is disposed close to the end face of the insulator 11, so that the insulator 11 extends laterally... Figure 3 The lateral X-direction limit is located between the two latching arms 24. Further integration Figure 4 and Figure 8In this embodiment, the pickup cover 20 also includes a plurality of stop pieces 231 extending downward from the two side walls 23 respectively, and the outer surface of the stop piece 231 is coplanar with the outer surface of the side wall. When the pickup cover 20 is placed on the insulator 11, the stop piece 231 covers the outer side of the two sides of the insulator 11. As long as the stop piece 231 can cover the outer side of the two sides of the insulator 11, it does not need to be precisely aligned as the buckle arm 24 and the slot 111 cooperate. Therefore, the installation of the pickup cover 20 is more convenient than the previous one. To ensure the pickup cover 20 can be stably placed on the insulator 11, the thickness of the stop piece 231 is less than the thickness of the side wall 23. Specifically, a portion of the side wall 23 extends downwards along its thickness direction (the outer portion) to form the stop piece 231 and covers the outer sides of both sides of the insulator 11; the other portion (the inner portion) does not extend to form the stop piece 231. For this portion of the side wall 23 where the stop piece is not extended, its lower surface abuts against the upper surface of the insulator 11. That is, the portion of the side wall located inside the stop piece 231 abuts downwards against the upper surface of the insulator 11. The outer surface of the stop piece 231 is coplanar with the outer surface of the side wall 23. To facilitate the placement of the pickup cover 20 on the insulator 11, the stop piece 231 also includes a guide surface 232 located near its lower end. To enable better positioning of the electrical connector 10, the insulator 11 also includes positioning posts 112 disposed adjacent to its two ends, the positioning posts 112 extending downward from the lower surface of the insulator 11.

[0038] Combination Figure 3 In this embodiment, when the pickup cover 20 is placed on the insulator 11, along the transverse X direction, the insulator 11 is limited by two latching arms 24 located at its two ends. Because there is a certain gap between the latching arms 24 and the end wall 22, the latching arms 24 can undergo a certain degree of elastic deformation, thus the insulator 11 can be tightly clamped between the two latching arms 24 along the transverse direction. Along the front-back direction Y, perpendicular to the transverse X, the insulator 11 is clamped between the stop pieces 231 of the two side walls 23. Along the up-down direction perpendicular to both the X and Y directions, downwards, the end wall 22 abuts against the upper surface of the insulator 11, and the lower portion of the side wall 23 abuts against the upper surface of the insulator 11; upwards, the latching arms 24 abut against the inner bottom surface of the slot 111 via the latching head 242. Therefore, the pickup cover 20 can be tightly fastened to the electrical connector 10, effectively preventing the pickup cover 20 from easily falling off.

[0039] This is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention should still fall within the scope of the present invention patent.
