Plug Connector Glue Blocks Eliminate Injection Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug connector designs require injection holes for low-pressure injection of inner films, increasing manufacturing complexity and costs due to the need for additional processing steps.
Innovation Solution
A plug connector design featuring a housing with a printed circuit board and cable connection protected by glue blocks, where the printed circuit board is received in a dual-housing structure with ribs and recessed holes for easy assembly and reduced manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If injection holes are provided for low-pressure injection of inner films, then the inner film can cover all welding points, but the manufacturing process complexity and costs increase
Solution Approach 1:
The patent removes the injection holes and inner film injection process entirely. Instead, it uses a pre-formed protective block that is directly placed over the soldering points, eliminating the complex injection molding process while still achieving protection of the welding points.
Solution Approach 2:
The protective block is made as a simple, inexpensive component that can be easily manufactured and applied. It serves its protective function and can be replaced if needed, rather than using a complex permanent injection-molded inner film structure.
2Reliability
If injection holes are provided for low-pressure injection of inner films, then the inner film can cover all welding points, but manufacturing costs increase
Solution Approach 1:
The patent eliminates the expensive inner film injection process by removing the injection holes. The protective function is achieved through a simpler protective block that does not require complex injection molding equipment or multi-step processes.
Solution Approach 2:
The protective block is designed as a simple, low-cost component that can be manufactured economically and applied directly, replacing the expensive injection-molded inner film solution.
3Ease of manufacture
If a dual-housing structure with ribs and recessed holes is used, then assembly is simplified and manufacturing costs are reduced, but the structure becomes more complex
Solution Approach 1:
The housing is divided into two separate parts (first housing and second housing) that can be manufactured independently and then assembled together. The ribs and recessed holes provide alignment features that simplify the assembly process, making the complex structure manageable through modular construction.
Solution Approach 2:
The ribs and recessed holes create a self-aligning assembly system where the components guide themselves into proper position during assembly, reducing the need for complex alignment procedures or additional fastening steps.

AI summary
A plug connector used to mate with the socket connector includes: a housing; a printed circuit board received in the housing, the circuit print board having plural soldering points; and a cable electrically connected to the soldering points of the printed circuit board, wherein the soldering points are provided with glue blocks to protect a connection between the printed circuit board and the cable.
