Solution Overview
Problem
Conventional lamp connectors have a complex structural design and assembly process, leading to poor engagement and shorter service life due to reliance on elastic force, which can result in loose connections and susceptibility to electromagnetic interference.
Innovation Solution
A lamp connector design featuring a connector body with slots and elastic members, including barbs with guide slopes, that securely position contacts within the body, enhancing assembly convenience and stability, and a separation wall to reduce electromagnetic interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a barb structure is used to engage the contact and body, then the engagement mechanism is achieved, but the structural design becomes more complicated and the assembly process becomes more troublesome
Solution Approach 1:
The patent changes the geometric parameters of the barb structure by adding a guide slope to the front surface of the barb. This parameter modification allows the contact to be guided during insertion, enabling self-positioning and self-centering without requiring complex additional structures, thus resolving the contradiction between engagement reliability and structural complexity
Solution Approach 2:
Instead of making the contact fit into the body, the patent inverts the approach by having the barb structure with guide slope actively guide the contact into proper position. The guide slope on the barb front surface allows the contact to ride up and position itself automatically, reversing the traditional fit direction and simplifying the overall structure
2Ease of manufacture
If the engagement relies on the elastic force of the front portions of the contacts, then the assembly is simple, but the connection is more likely to loosen and the service life is shorter
Solution Approach 1:
The guide slope on the barb front surface performs preliminary action by guiding and positioning the contact during insertion before the final engagement occurs. This preliminary guidance ensures proper alignment and positioning, preventing future loosening and extending service life while maintaining assembly simplicity
Solution Approach 2:
The barb structure with guide slope enables self-service functionality where the contact automatically positions and centers itself during insertion without requiring external alignment tools or complex assembly procedures. The elastic force combined with the guide slope creates a self-aligning mechanism that maintains connection stability
3Volume of moving object
If the positive contact and the negative contact are disposed in a common accommodation space, then the structure is compact, but they are more likely to be affected by electromagnetic interference
Solution Approach 1:
The patent applies segmentation by dividing the accommodation space into separate regions for positive and negative contacts. The body structure includes separate accommodating spaces or at least separate positioning regions for each contact type, physically isolating them to reduce electromagnetic interference while maintaining overall structural compactness

AI summary
A lamp connector comprises a contact and a connector body having an accommodation space accommodating the contact. The contact has a positioning hole. The connector body has a slot extending along an insertion direction of the contact and confining the contact thereinside. The accommodation space has a elastic member with a barb that corresponds to the positioning hole and has a guide slope. The contact can easily overcome elastic force of the elastic member, overpass the guide slope to go into the accommodation space and is longitudinally confined to the slot. Then, elastic force springs the barb into the positioning hole. Thus, the contact is transversely positioned in the plastic body. Thereby, the contact can be assembled to the plastic body faster, more conveniently and more firmly; the electric connection of the male plug and the female socket is more stable and more resistant to electromagnetic interference.
