An electrical connector (1) includes an insulative housing (2) and at least one contact (3) received in the housing. The housing defines a receiving cavity (23) therein, at least one receiving groove (216) communicating with the receiving cavity, a recessing groove (219) recessing outwards from an inner face (2161) of the at least one receiving groove and a locking hole (218) recessing outwards from an inner face (2190) of the recessing groove. The at least one contact defines a base portion (31) received in the receiving groove and an elastic arm (32) extending from the base portion and projecting into the receiving cavity, and the base portion defines an elastic locking portion (312) passing through the recessing groove and projecting into the locking hole in an elastic deformation manner to lock with the locking hole.

A cable assembly comprises an insulative housing having a body portion and a mating portion extending forward from a front side of the body portion along a mating direction. The body portion forms a supporting portion protruding rearward and extending along a transversal direction thereof. A plurality of contacts are disposed in the insulative housing with front contacting sections exposed in the mating section and rear tails opposite to the front contacting sections. A printed circuit board stands within the supporting portion and electrically and mechanically connects with the tails of the contact. A cable connects with a free end of the printed circuit board and a cover is assembled onto the insulative housing to enclose said printed circuit board and the cable therein. The configuration of the cable assembly is compact and meets the low profile demand.

An electrical connector assembly includes an insulative housing (10) having a forward mating port (100) in a suspension manner, a plurality of recesses (112), arranged in a matrix manner, formed in the housing (10) under the mating port (100) so as to form a plurality of corresponding partitions (111) among the recesses (112) for support of the mating port (10). The matrix array of recesses (112) is arranged to strengthen the rigid of the housing (10) under the mating port (100) so as to prevent the deformation of the mating port (100), which is influenced from the insert force under a condition when the electrical connector mates with a complementary connector.

A battery connector comprises a terminal block and a first and second terminal received in the terminal block. The terminal block comprises a base, a first protecting wall and a second protecting wall. The base, the first and second protecting wall together defines a receiving chamber. The first protecting wall defines at least a flange; the second protecting wall defines at least a resilient retaining arm relative to the flange. Under the cooperation of the flange and the resilient retaining arm, a reliable electrical connection is established between the first terminal, the second terminal and a coin battery.

An electrical connector assembly includes an insulative housing (10) including a forwardly protruding mating port in a suspension manner. A plurality of contacts (30) is disposed in the housing each defining an L-shaped base portion (302) including a horizontal section and a vertical section. A cover (20) is attached onto the insulative housing and includes a vertical plate (201) for covering the vertical section of each contact (30), the vertical plate (201) defining a plurality of through slots (211) for heat dissipation. This configuration of the cover has the capability of providing good heat dissipation for the electrical connector.

Systems and methods to assist wireless telecom service providers to determine the optimal core network evolution plan in a network planning time period. Total cost of ownership of wireless core networks is generally modeled to include capital expenditure, customer acquisition and retention cost, network operational cost and staffing and engineering cost. The total cost of ownership model is used to determine the optimal core network evolution plan at different layers of the core networks, which are modeled as a number of abstract networks in mathematical terms. A core network evolution optimization algorithm determines the optimal number of core network configurations and when to deploy the configurations in the planning period in order to minimize the total cost of ownership. A multi-level serving area optimization algorithm determines an optimal core network configuration at a given point of time.

An electrical connector comprises a terminal block, a terminal received in the terminal block and an elastic connecting portion electrically connecting with the terminal. The terminal block defines a first receiving cavity, a second receiving cavity opposite to the first receiving cavity and a spaced portion spacing the first receiving cavity and the second receiving cavity. The spaced portion defines a receiving channel and a inserting slot communicating with the receiving channel. The elastic connecting portion is received in the second receiving cavity and electrically connects with the terminal.
